    Nonarteritic ischemic optic neuropathy is characterized by sudden and painless loss of vision in one eye, accompanied by pallid swelling of the optic disc. Although various medical interventions, such as corticosteroids and phenytoin sodium, have been used to treat nonarteritic ischemic optic neuropathy, no therapy has been proven effective. The objective of this review is to assess the safety and efficacy of surgical treatment compared with other treatment or usual care in people with nonarteritic ischemic optic neuropathy. We searched the Cochrane Controlled Trials Register - Central and MEDLINE. The most recent searches were performed in December 1997. We included randomized trials comparing surgery to no surgery in people with nonarteritic ischemic optic neuropathy. We obtained full copies of all potentially relevant articles. Only one article described a randomized trial of surgery and it was eligible for inclusion. No formal assessment of quality was done. One reviewer extracted data. No synthesis was required, as there was only one trial. The one trial identified randomized 258 patients. The only published report with outcomes data for that trial presents preliminary results from 244 patients who had achieved six months of follow-up at the time of the report. Participants assigned to surgery did no better than participants assigned to careful follow-up regarding improved visual acuity of three or more lines of vision at six months: 32.6% of the surgery group improved compared with 42.7% of the careful follow-up group. The adjusted odds ratio (OR), adjusted for baseline visual acuity and diabetes, comparing the two groups for three or more lines improvement was 0.74 (95% confidence interval (CI) 0.39 to 1. 38) (surgery group improvement was worse than careful follow-up). In addition, participants receiving surgery had a significantly greater risk of losing three or more lines of vision at six months: 23.9% in the surgery group worsened compared with 12.4% in

    Nonarteritic anterior ischemic optic neuropathy (NAION) is the most common cause of an acute optic neuropathy over the age 50 with an annual incidence of 2-10/100 000. Most patients are left with a permanent decrease in visual acuity and visual field loss. No approved treatment has conclusively reversed the process or prevented a second event that typically involves the previously unaffected eye. Many medical and surgical treatments have been proposed with conflicting results. The goal of this review is to present current data in order to permit clinicians and patients to make an educated decision about treatment. Recently, there has been a flurry of case reports, small clinical trials and testing in animal models of NAION for various treatments for NAION and this review attempts to present the data concisely with the authors' opinions about the reliability of the data. To date, there is no class I evidence of benefit for the treatment of NAION; however, the aphorism attributed to Carl Sagan, PhD aptly applies: 'Absence of evidence is not evidence of absence'.

    Full Text Available We report the first case of nonarteritic anterior ischemic neuropathy (NAION associated with double thrombophilia: protein S deficiency and prothrombin G20210A mutation. A 58-year-old man is presented including the clinical and laboratory findings, cardiovascular profile and thrombophilia screening. The patient presented with 3/10 vision and an inferior altitudinal defect in the right eye. Funduscopic examination of the right eye revealed a hyperemic optic disk with blurred superior optic disk border and sectoral nerve fiber layer edema. Complete blood count, erythrocyte sedimentation rate and C-reactive protein were normal, suggesting a NAION. A workup of cardiovascular risk factors revealed hyperlipidemia, arterial hypertension and high-risk asymptomatic coronary artery disease. Due to the family history of deep vein thrombosis in the patient’s daughter, a thrombophilia screening was additionally performed. The results revealed a double thrombophilic defect, namely congenital protein S deficiency and heterozygosity for prothrombin G20210A mutation, which were also identified in the patient’s daughter. Anticoagulant warfarin therapy was initiated and the patient underwent a triple bypass surgery. At three-month follow-up, the right optic disk edema had resolved, leaving a pale superior optic nerve head. Visual acuity in the right eye had slightly improved to 4/10; however, the dense inferior altitudinal field defect had remained unchanged. The patient is currently treated with warfarin, atorvastatin, irbesartan and metoprolol. This case suggests that the first line of investigation in all patients with NAION involves assessment of cardiovascular risk factors. However, careful history taking will identify NAION patients who are eligible for additional thrombophilia screening: young patients without vasculopathic risk factors, bilateral or recurrent NAION, idiopathic or recurrent venous thromboembolism (VTE, positive family history of VTE

    Full Text Available Purpose. To describe a patient who developed bilateral, simultaneous nonarteritic anterior ischemic optic neuropathy (NAION after ingestion of Sildenafil citrate (Viagra for erectile dysfunction. Methods. Observational case report. Results. A 60-year-old diabetic man noted sudden decrease of vision in both eyes 16 hours after his third consecutive 50 mg daily Sildenafil ingestion. A diagnosis of bilateral NAION was made and he was treated for three days with methylprednisolone 1 g/d intravenously, followed by oral prednisone 75 mg/d. Final visual acuity was 20/50 right eye (OD and 20/20 left eye (OS. He had preexisting diabetes. Conclusion. This is the first reported case of simultaneous bilateral NAION occurred in a diabetic patient early after Sildenafil intake. Patients with predisposing conditions such as diabetes have to be warned against the use of PDE inhibitors.

    We present an interesting case with nonarteritic anterior ischemic optic neuropathy (NAION) accompanied by Buerger's disease. A 43-year-old man was referred to our neuro-ophthalmology clinic with a complaint of visual deterioration in the left eye that started 5 days ago. He suffered from Buerger's disease, and he had acute pain in the right lower limb below the knee. His best corrected visual acuity was 10/10 in the right eye and 2/10 in the left eye by Snellen chart. There was a relative afferent pupil defect in the left eye. The right optic disc was normal on fundus examination, and blurring, hemorrhagic swelling was found at the left optic disc. Inferior altitudinal visual field defect was observed in the left eye. Neurological examination was normal. Computed tomography angiography scan revealed occlusion in the right posterior tibial artery. Brain imaging and laboratory tests such as blood analyses, genetic screening, coagulation, and lipid panels were unremarkable. NAION may occur in patients with Buerger's disease, but it is extremely rare. Therefore, clinicians should be aware of this rare association.

    To describe changes of the retinal peripapillary microvasculature on optical coherence tomography angiography (OCT-A) in non-arteritic anterior ischemic optic (NAION) neuropathy. Observational study of 10 patients at the acute phase of NAION. OCT-A was performed using a 3mm×3mm square centered on the optic disc (Cirrus HD-OCT with Angioplex, Carl Zeiss Meditec, Dublin, CA). A qualitative comparison was made with the healthy fellow eye of each patient. All patients had a fluorescein angiography (HRA2, Heidelberg, Germany) and a visual field examination (Octopus 101 ® , Haag-Streit, USA). In the affected eyes, OCT-A showed clear modifications in the radial peripapillary network. In all these eyes, a focal disappearance of the superficial capillary radial pattern was present, twisted and irregular. In 8 eyes, there was also a lack of vascularization in some focal areas, appearing as dark areas. No correlation was found between the topography of the vascular alteration shown on OCT-A and visual field pattern defects. OCT-A is a new imaging technology able to demonstrate easily and safely the changes in the peripapillary capillary network during the acute phase of NAION. These changes are likely related to a decrease of the prelaminar optic nerve blood flow during the acute phase of NAION. Visual field defects are not correlated with OCT-A images, suggesting that they may be due mainly to disturbances in posterior ciliary artery blood flow. Copyright © 2016 Elsevier Masson SAS.

    To determine whether genetic or acquired thrombophilias and other risk factors are associated with nonarteritic anterior ischemic optic neuropathy (NAION). Retrospective case-control study. Sixty-one patients with NAION diagnosed between 1984 and 1997. Ninety consecutive patients who visited the Eye Institute made up the control group. Protein C, protein S, antithrombin III, lupus anticoagulant, and three recently described prothrombotic polymorphisms (i.e., factor V G1691A, factor II G20210A, and methylenetetrahydrofolate reductase [MTHFR] C677T) were analyzed. In addition, risk factors for arteriosclerotic vascular disease were assessed. Parameters of thrombophilia. None of the thrombophilic markers (genetic and acquired) constituted a significant risk factor for NAION. Ischemic heart disease, hypercholesterolemia, and diabetes mellitus were discerned as risk factors for NAION with odds ratios of 2.9 (95% confidence interval [CI], 1.3-6.4), 2.6 (95% CI, 1.2-5.5), and 2.3 (95% CI, 1.1-4.8), respectively. Multiple logistic regression analysis indicated that ischemic heart disease and hypercholesterolemia exerted an additive risk for NAION with a combined odds ratio of 4.5 (95% CI, 1.4-14.5). However, none of these risk factors statistically predicted second eye involvement. NAION was not found to be associated with thrombophilic risk factors, yet it was related to ischemic heart disease, hypercholesterolemia, and diabetes mellitus.

    Non-arteritic anterior ischemic optic neuropathy (N-AION) is caused by acute ischemic infarction of the optic nerve head, supplied by the posterior ciliary arteries. Thrombophilia is the tendency/predisposition to vascular thromboses of arteries and veins, and the existence of thrombophilic risk factors leads to blood hypercoagulability and potentially increased risk for thromboses. To investigate whether there is an association between N-AION and a wide spectrum of thrombophilic risk factors. Seventy-seven consecutive cases of confirmed N-AION and 60 age- and sex-matched consecutive controls constituted the study group. Fibrinogen levels, deficiency of proteins C, S, ATIII, lupus anticoagulant, activated protein C resistance, factor V Leiden, factor V H1299R, factor II G20210A, MTHFR C677T, MTHFR A1298C, GPIIIa A1/A2, and ACE I/D polymorphisms were analysed. Statistical analysis of the plasma proteins in our study demonstrated that the only significant difference was the one concerning protein S levels. In particular, the mean value for N-AION patients was 78.8% +/- 21.2, and for the control group the mean value was 88% +/- 21.2 (p = 0.013). Despite the above-mentioned result, there was not any statistical difference between the two subgroups regarding actual protein S deficiency, as 9/77 (11.7%) patients and 4/60 (6.7%) controls had protein S levels below 60% (p = 0.32). In our study sample, homozygosity for MTHFR C677T polymorphism in the study group as a whole, and the presence of at least one A2 allele of GPIIIa in the subgroup of male patients as compared to healthy male controls, proved to be the most significant thrombophilic risk factors, with odds ratios of 16.78 (95% C.I 0.96-294.42, p = 0.054) and 4.6 (95% C.I 1.52-13.88, p = 0.007) respectively. Screening for these polymorphisms would probably constitute a valuable procedure in N-AION patients, as they may have an important contribution to the pathogenesis of the disease.

    Full Text Available To compare the deep optic nerve head (ONH structure between normal-tension glaucoma (NTG and nonarteritic anterior ischemic optic neuropathy (NAION and also in healthy subjects as a control using enhanced depth imaging (EDI spectral-domain optical coherence tomography (SD-OCT.This prospective cross-sectional study included 21 NAION patients who had been diagnosed as NAION at least 6 months prior to study entry, and 42 NTG patients and 42 healthy controls who were matched with NAION patients in terms of age, intraocular pressure (IOP, and optic disc area. The retinal nerve fiber layer (RNFL thickness in the affected sector was also matched between NAION and NTG patients. The ONH was imaged using SD-OCT with the EDI technique. The anterior lamina cribrosa surface depth (LCD and average prelaminar tissue (PT thickness were measured in a sector of interest in each eye and compared among the three groups.In the sector-matched comparison, LCD was largest in NTG patients, followed by NAION patients, while PT was thinner in NTG patients than in NAION patients (all P < 0.001. NAION patients had a comparable LCD and a thinner PT relative to normal controls (P = 0.170 and < 0.001, respectively.The deep ONH configuration is strikingly different between NTG and NAION. The differing features provide comparative insight into the pathophysiology of the two diseases, and may be useful for differential diagnosis.

    Glucose-6-phosphate dehydrogenase (G6PD) deficiency is one of the most common human genetic abnormalities, with a high prevalence in Sardinia, Italy. Evidence indicates that G6PD-deficient patients are protected against ischemic heart and cerebrovascular disease and retinal vein occlusion. The purpose of this study was to assess the frequency of G6PD deficiency in Sardinian patients with nonarteritic anterior ischemic optic neuropathy (NAION) and ascertain whether G6PD deficiency may offer protection against NAION. Erythrocyte G6PD activity was determined by using a quantitative assay in 140 patients with NAION and 280 age- and gender-matched comparison patients. Conditional logistic regression models were used to investigate the association between G6PD deficiency and NAION. G6PD deficiency was found in 7 (5%) patients with NAION and 34 (12.1%) control subjects. Differences between cases and controls were statistically significant (P = 0.02). Conditional logistic regression analysis, including as covariates G6PD deficiency, hypertension, diabetes, and hypercholesterolemia, revealed that G6PD deficiency was significantly associated with decreased risk for NAION (odds ratio [OR] = 0.4, 95% confidence interval [CI] = 0.17-0.94, P = 0.035). Conditional logistic regression analyses, including systolic or diastolic blood pressure and plasma glucose and cholesterol levels confirmed that G6PD deficiency was associated with a decreased risk for NAION, but the ORs were not significant at the 0.05 significance level (P = 0.085 and P = 0.071). Models including gender x G6PD deficiency interaction disclosed that gender was not an effect modifier of G6PD deficiency (P > 0.20). The frequency of G6PD deficiency in patients with NAION was significantly lower than expected. Results suggest that G6PD-deficient patients in the Sardinian population have a significantly decreased risk of having NAION.

    Full Text Available Background: Non-arteritic anterior ischemic optic neuropathy (NAION is the most common acute optic neuropathy in patients over the age of 50 and is the second most common cause of permanent optic nerve-related visual loss in adults after glaucoma. Although the precise cause of NAION remains elusive, the etiology of NAION is believed to be multifactorial. Aims: To evaluate the utility of neutrophil-to-lymphocyte ratio (NLR as a simple and readily available prognostic factor for clinical disease activity in patients with NAION. Study Design: Case-control study. Methods: Forty-five patients with the diagnosis of NAION and 50 age- and sex-matched controls with/without any systemic or ocular diseases except cataract were retrospectively enrolled in the study. Demographic characteristics and laboratory findings including complete blood count of all patients and control subjects were obtained from the electronic medical record. The neutrophil and lymphocyte counts were recorded and the NLR was calculated. Results: White blood cell, neutrophil, NLR and platelet values of the NAION patients were significantly higher than those of the controls (p<0.001, p<0.001, p=0.004, p=0.037, respectively. Initial NLR values were negatively correlated with initial and the third month best corrected visual acuity levels in the study group. The optimum NLR cut-off point for NAION was 1.94. Conclusion: NLR could be considered as a new inflammatory marker for assessment of the severity of inflammation in NAION patients with its quick, cheap, easily measurable property with routine complete blood count analysis.

    Scanning laser polarimetry (SLP) reveals abnormal retardance of birefringence in locations of the edematous peripapillary retinal nerve fiber layer (RNFL), which appear thickened by optical coherence tomography (OCT), in nonarteritic anterior ischemic optic neuropathy (NAION). We hypothesize initial sector SLP RNFL abnormalities will correlate with long-term regional visual field loss due to ischemic injury. We prospectively performed automated perimetry, SLP, and high definition OCT (HD-OCT) of the RNFL in 25 eyes with acute NAION. We grouped visual field threshold and RNFL values into Garway-Heath inferior/superior disc sectors and corresponding superior/inferior field regions. We compared sector SLP RNFL thickness with corresponding visual field values at presentation and at >3 months. At presentation, 12 eyes had superior sector SLP reduction, 11 of which had inferior field loss. Six eyes, all with superior field loss, had inferior sector SLP reduction. No eyes had reduced OCT-derived RNFL acutely. Eyes with abnormal field regions had corresponding SLP sectors thinner (P = 0.003) than for sectors with normal field regions. During the acute phase, the SLP-derived sector correlated with presentation (r = 0.59, P = 0.02) and with >3-month after presentation (r = 0.44, P = 0.02) corresponding superior and inferior field thresholds. Abnormal RNFL birefringence occurs in sectors corresponding to regional visual field loss during acute NAION when OCT-derived RNFL shows thickening. Since the visual field deficits show no significant recovery, SLP can be an early marker for axonal injury, which may be used to assess recovery potential at RNFL locations with respect to new treatments for acute NAION.

    To report on the correlation of structural damage to the axons of the optic nerve and visual outcome following bilateral non-arteritic anterior ischemic optic neuropathy. A retrospective review of the medical records of 25 patients with bilateral sequential non-arteritic anterior ischemic optic neuropathy was performed. Outcome measures were peripapillary retinal nerve fiber layer thickness measured with the Stratus optical coherence tomography scanner, visual acuity and visual field loss. Median peripapillary retinal nerve fiber layer (RNFL) thickness, mean deviation (MD) of visual field, and visual acuity of initially involved NAION eyes (54.00 µm, -17.77 decibels (dB), 0.4, respectively) were comparable to the same parameters measured following development of second NAION event in the other eye (53.70 µm, p = 0.740; -16.83 dB, p = 0.692; 0.4, p = 0.942, respectively). In patients with bilateral NAION, there was a significant correlation of peripapillary RNFL thickness (r = 0.583, p = 0.002) and MD of the visual field (r = 0.457, p = 0.042) for the pairs of affected eyes, whereas a poor correlation was found in visual acuity of these eyes (r = 0.279, p = 0.176). Peripapillary RNFL thickness following NAION was positively correlated with MD of visual field (r = 0.312, p = 0.043) and negatively correlated with logMAR visual acuity (r = -0.365, p = 0.009). In patients who experience bilateral NAION, the magnitude of RNFL loss is similar in each eye. There is a greater similarity in visual field loss than in visual acuity between the two affected eyes with NAION of the same individual.

    Ciliary neurotrophic factor (CNTF) has been shown to protect retinal ganglion cells (RGCs) in traumatic optic nerve injury. We sought to evaluate this neuroprotective effect of CNTF after an ischaemic event using rodent anterior ischaemic optic neuropathy (rAION), a mouse model of non-arteritic anterior ischaemic optic neuropathy (NAION). We induced rAION in Thy1-cyan fluorescent protein (CFP) transgenic mice by exposing the optic nerve to frequency doubled neodymium yttrium aluminium garnet laser pulses following intravenous rose bengal injection. One day after rAION induction, an intravitreal injection of 0.75 μg CNTF or vehicle (sham injection) was given. Animals were euthanised on day 15 after induction, tissues isolated and CFP cells in the RGC layer were counted using stereology in flat-mounted retina. The average number of CFP-positive (CFP+) cells was determined for each study group and the percentages of RGC loss were compared between the different groups. Two weeks after rAION induction, significantly more (CFP+) cells were preserved in CNTF-treated eyes than in sham-injected controls. Sham-treated animals showed a 58% loss of CFP+ cells. In contrast, CFP+ cell density in CNTF-treated eyes decreased by only 10%, when compared with untreated control eyes. This increased survival was statistically significant (pCNTF exerts a neuroprotective effect in ischaemic optic nerve injury and promotes RGC survival, suggesting that CNTF may be effective in the clinical treatment of human NAION.

    The purpose of the study was to examine the brain and the visual pathway of patients with non-arteritic anterior ischaemic optic neuropathy (NAION) by using conventional MRI (cMRI) and volumetric magnetisation transfer imaging (MTI). Thirty NAION patients, aged 67.5 {+-} 8.14 years, and 28 age- and gender-matched controls were studied. MTI was used to measure the magnetisation transfer ratio (MTR) of the chiasm and for MTR histograms of the brain. The presence of areas of white matter hyperintensity (WMH) was evaluated on fluid-attenuated inversion recovery (FLAIR) images. Area of the optic nerves (ONs) and volume of the chiasm were assessed, as were coronal short-tau inversion recovery (STIR) and MTI images, respectively. More areas of WMH were observed in patients (total 419; mean 14.4; SD 19) than in controls (total 127; mean 4.7; SD 5.7), P < 0.001. Area (in square millimetres) of the affected ONs, volume(in cubic millimetres) and MTR (in percent) of the chiasm (10.7 {+-} 4.6), (75.8 {+-} 20.2), (56.4 {+-} 6.5), respectively, were lower in patients than in controls (13.6 {+-} 4.3), (158.2 {+-} 75.3) (62.1 {+-} 6.2), respectively, P < 0.05. Mean MTR of brain histograms was lower in patients (53.0 {+-} 8.0) than in controls (58.0 {+-} 5.6), P < 0.05. NAION is characterised by decreased ON and chiasmatic size. The low MTR of the chiasm and brain associated with increased areas of WMH may be suggestive of demyelination and axonal damage due to generalised cerebral vascular disease. (orig.)

  1. Cataract Surgery in Anterior Megalophthalmos: A Review

    Science.gov (United States)

    GALVIS, Virgilio; TELLO, Alejandro; M. RANGEL, Carlos

    2015-01-01

    Anterior megalophthalmos is characterized by megalocornea associated with a very broad anterior chamber and ciliary ring elongation. It is also called X-linked megalocornea. It is accompanied by early development of cataracts, zonular anomalies, and, rarely, vitreoretinal disorders. Subluxation of a cataract can occur in cataract surgery because of zonular weakness. In addition, in most patients, standard intraocular lens (IOL) decentration is a risk because of the enlarged sulcus and capsular bag. These unique circumstances make cataract surgery challenging. To date, several approaches have been developed. Implantation of a retropupillary iris-claw aphakic intraocular lens may be a good option because it is easier than suturing the IOL and can have better and more stable anatomic and visual outcomes, compared to other techniques.

    Full Text Available Improving the outcomes in reconstructive surgery of the anterior cruciate ligament (ACL requires a rigorous and permanent assessment of specific parameters. Therefore, we can increase the degree of reproducibility of the procedure and identify particular aspects in order to achieve an adequate and individualized therapeutic approach for each case. In order to accomplish this goal, the use of complex means (scores of quantifying results is required. That includes objective means of verifying the parameters in knee surgery, and a subjective evaluation of the patient in order to compare the results.

    Full Text Available Successful anterior cruciate ligament (ACL reconstruction with tendon graft requires extensive tendon-to-bone healing in the bone tunnels and progressive graft ligamentization for biological, structural, and functional recovery of the ACL. Improvement in graft-to-bone healing is crucial for facilitating early, aggressive rehabilitation after surgery to ensure an early return to pre-injury activity levels. The use of various biomaterials for enhancing the healing of tendon grafts in bone tunnels has been developed. With the biological enhancement of tendon-to-bone healing, biological fixation of the tendon graft in the tunnel can be achieved in ACL reconstruction.

    Anterior eye segment surgeries are usually video-recorded. If we are able to efficiently analyze surgical videos in real-time, new decision support tools will emerge. The main anatomical landmarks in these videos are the pupil boundaries and the limbus, but segmenting them is challenging due to the variety of colors and textures in the pupil, the iris, the sclera and the lids. In this paper, we present a solution to reliably normalize the center and the scale in videos, without explicitly segmenting these landmarks. First, a robust solution to track the pupil center is presented: it uses the fact that the pupil boundaries, the limbus and the sclera / lid interface are concentric. Second, a solution to estimate the zoom level is presented: it relies on the illumination pattern reflected on the cornea. The proposed solution was assessed in a dataset of 186 real-live cataract surgery videos. The distance between the true and estimated pupil centers was equal to 8.0 ± 6.9% of the limbus radius. The correlation between the estimated zoom level and the true limbus size in images was high: R = 0.834.

    2014-04-01

    Full Text Available Purpose: The aim of this study was to investigate possible predictive factors related to anterior chamber fibrin formation after vitreoretinal surgery in a large series of patients. Methods: The data of 185 eyes of 185 patients submitted to vitreoretinal surgery was reviewed. The following variables were evaluated: the postoperatively presence of fibrin, age, diabetes mellitus, the vitrectomy system gauge (20, 23 or 25 gauge, the type of vitreous substitute, the influence of prior surgical procedures and the combination with cataract extraction. To evaluate predictive factors for anterior chamber fibrin formation, univariate analysis was performed. A multivariate stepwise logistic regression model was adjusted to investigate factors associated with fibrin formation (p<0.05. Results: Fibrinoid anterior chamber reaction was found in 12 (6.4% patients. For multivariate logistic regression analysis, balanced salt solution (BSS, the chance of fibrin occurrence was 5 times greater (odds ratio 4.83, CI 95% 1.302 - 17.892; p=0.019, while combination with phacoemulsification increased the chance of fibrin formation by 20 times (odds ratio 20, CI 95% 2.480 - 161.347; p=0.005. No significant difference was found regarding other variables. Conclusion: Anterior chamber fibrin formation is an unwanted complication after vitreoretinal surgery. Factors such as combined performance of phacoemulsification and the use of balanced salt solution as a vitreous substitute may predispose the occurrence of this complication.

    2010-02-01

    The human eye is a favored target for laser surgery due to its accessibility via the optically transparent ocular tissue. Femtosecond lasers with confined tissue effects and minimized collateral tissue damage are primary candidates for high precision intraocular surgery. The advent of compact diode-pumped femtosecond lasers, coupled with computer controlled beam delivery devices, enabled the development of high precision femtosecond laser for ophthalmic surgery. In this article, anterior segment femtosecond laser applications currently in clinical practice and investigation are reviewed. Corneal procedures evolved first and remain dominant due to easy targeting referenced from a contact surface, such as applanation lenses placed on the eye. Adding a high precision imaging technique, such as optical coherence tomography (OCT), can enable accurate targeting of tissue beyond the cornea, such as the crystalline lens. Initial clinical results of femtosecond laser cataract surgery are discussed in detail in the latter portion part of the article.

    The anterior cruciate ligament is the most commonly disrupted ligament in the knee in high-performance athletes. Most recently, advancements in surgical technique and graft fixation have enabled athletes to participate in early postoperative rehabilitation, focusing on range of motion and progressing to patellar mobilization, strengthening, and neuromuscular control. Several rehabilitation protocols exist with variations in specific exercises, progression through phases, and key components. The ultimate goal of rehabilitation is to return the athlete to preinjury performance level, including motion and strength, without injuring or elongating the graft. Each athlete is unique; thus, safe return to play should be individualized rather than follow a particular postoperative month or time line. This article provides an overview of the application and the scientific basis for formulating a rehabilitation protocol prior to and following anterior cruciate ligament surgery.

    1998-01-01

    Full Text Available Anterior chamber aspirate cultures were done for 66 patients who underwent either an uncomplicated intracapsular cataract extraction, extracapsular cataract extraction with posterior-chamber intraocular lens implantation, or phacoemulsification with posterior-chamber intraocular lens implantation. The aspirate was obtained at the time of wound closure. The aspirates were immediately transferred to the microbiology laboratory where one drop of the aspirate was placed on a glass slide for gram stain, and the remainder was unequally divided and inoculated into blood agar, chocolate agar and thioglycolate broth. The cultures were incubated at 37° C with 5% CO2 and held for 5 days. Of 66 patients 4 (6%, had smear-positive anterior chamber aspirates. None of the aspirates showed any growth on any of the 3 culture media used. None of the eyes in the study developed endophthalmitis. This study concludes that there is no contamination of the anterior chamber by viable bacteria after cataract surgery, irrespective of the mode of intervention.

    To study postoperative complications of arthroscopic anterior cruciate ligament (ACL) reconstruction performed as an outpatient compared with same surgery performed as a regular admission (inpatient). A study was conducted on a historical cohort of 342 patients (115 outpatients vs 227 inpatients) who underwent arthroscopic ACL primary ligamentoplasty (2004-2012). A review was performed on the demographic, surgical and hospital variables. A study was made of early complications (60 days postoperative) including visits to emergency department and readmissions. A descriptive and bivariate distribution analysis was performed between groups, with the grouping criterion: performing of the surgery with or without admission. The Chi-square test was used for qualitative variables and Mann-Whitney U test for quantitative. Limit significance p<0.05. Overall, there were 13.2% emergency department visits (mean of 1.24 visits) with an average delay of 8.22 days after discharge. pain not controlled with analgesia (6.7%), hemarthrosis that required arthrocentesis (4.4%), fever (3.2%), deep vein thrombosis (0.6%), cellulitis (0.6%), septic arthritis that required arthroscopic debridement (0.3%), and others (1.2%) including problems with immobilization. The hospital readmissions (2.3%) were for surveillance and monitoring of the surgical wound. In the bivariate analysis no statistically significant differences were found between groups as regards the sociodemographic characteristics of the patients or the complications recorded. The most frequent complications recorded were acute pain, hemarthrosis and fever. Serious complications (deep vein thrombosis, septic arthritis or need for hospital readmission) were rare. Outpatient arthroscopic ACL repair is a common technique that can be performed safely by surgery without admission, with an overall low complication rate with no differences between outpatients and inpatients.

  12. Orthodontic treatment of anterior open bite: a review article--is surgery always necessary?

    Science.gov (United States)

    Reichert, Isabelle; Figel, Philipp; Winchester, Lindsay

    2014-09-01

    Anterior open bite cases are very difficult to treat satisfactorily because of their multifactorial aetiology and their very high relapse rate. Dependent on the origin of the anterior open bite malocclusion and the patient's age, there are several treatment possibilities ranging from deterrent appliances, high-pull headgear, fixed appliances with and without extractions to orthognathic surgery, and skeletal anchorage with miniplates or miniscrews. The gold standard treatment of skeletal anterior open bite cases is the combined approach of orthodontic treatment with fixed appliances and orthognathic surgery. In recent years, temporary anchorage devices (TAD) have been developed to correct anterior open bites orthodontically. With the introduction of TAD as an effective treatment modality, orthognathic surgery may be avoidable in selected anterior open bite cases. This is a relatively new technique and to date there remains a lack of evidence of long-term stability of anterior open bite closure with TAD.

    Full Text Available Objective. The purpose of this study was to evaluate a new questionnaire to assess outcomes related to the midline anterior lumbar approach and to identify risk factors for negative patient responses. Methods. A retrospective review of 58 patients who underwent anterior lumbar surgery at a single institution for either degenerative disc disease or spondylolisthesis in 2009 was performed. The outcome measures included our newly developed Anterior Lumbar Surgery Questionnaire (ALSQ, ODI, and EQ-5D. Results. There were 58 patients available for followup, 27 women and 31 men. The average age at surgery was 50.8 years, with an average followup of 2.92 years. The average change in ODI was 34.94 (22.7 and EQ-5D was 0.28 (0.29. The rate of complications with the anterior approach was 10.3% and there was one male patient (3.2% with retrograde ejaculation. Determination of the effectiveness of the new ALSQ revealed that it significantly correlated to the EQ-5D and ODI (P<0.05. Smoking was associated with a negative response on thirteen questions. BMP use was not associated with a negative response on any sexual function questions. Conclusions. Our new Anterior Lumbar Surgery Questionnaire determines patient perceived complications related to the midline anterior lumbar surgical approach.

    The anterior cruciate ligament (ACL) is one of the more studied structures in the knee joint. It is not a tubular structure, but is much narrower in its midsubstance and broader at its ends, producing an hourglass shape. The ACL is composed of 2 functional bundles, the anteromedial and posterolateral bundles, that are named for their location of insertion on the anterior surface of the tibial plateau. Although the relative contribution in terms of total cross-sectional area of the ACL has been noted to be equal in regards to each bundle, dynamically these bundles demonstrate different properties for knee function.

    A retrospective study. Anterior cervical fusion surgery is widely used procedure in cervical spondylosis. When considering the blood reinfusion strategies of cervical fusion surgery, the amount of blood loss is one of the key elements. We usually calculate the blood loss according to the surgical bleeding plus the postoperative drainage; however, this method ignores the possibility that there may be hidden blood loss (HBL). We performed a retrospective study to determine the risk factors for HBL in patients who underwent anterior cervical fusion surgery for degenerative spine from 2013 to 2016. The Pearson correlation, Spearman correlation, and multivariate liner analysis were used to find association between patient characteristics and HBL. A total of 107 consecutive patients who underwent anterior cervical fusion surgery for degenerative spine in our hospital were reviewed. The amount of HBL was 261 mL, or 50% of the total blood loss. According to the model of multiple linear regression analysis, patient sex (P = 0.028) and American Society of Anesthesiologists physical status classification (P = 0.029) were independent risk factors contributing to HBL, but preoperative hematocrit was not (P = 0.741). We concluded that sex and American Society of Anesthesiologists physical status classification were independent risk factors of HBL in anterior cervical fusion surgery. In addition, there was a high proportion of HBL in anterior cervical fusion. When considering the strategies of transfusion, we should pay attention to the risk factors for HBL.

    Multicenter retrospective case series and review of the literature. To determine the rate of esophageal perforations following anterior cervical spine surgery. As part of an AOSpine series on rare complications, a retrospective cohort study was conducted among 21 high-volume surgical centers to identify esophageal perforations following anterior cervical spine surgery. Staff at each center abstracted data from patients' charts and created case report forms for each event identified. Case report forms were then sent to the AOSpine North America Clinical Research Network Methodological Core for data processing and analysis. The records of 9591 patients who underwent anterior cervical spine surgery were reviewed. Two (0.02%) were found to have esophageal perforations following anterior cervical spine surgery. Both cases were detected and treated in the acute postoperative period. One patient was successfully treated with primary repair and debridement. One patient underwent multiple debridement attempts and expired. Esophageal perforation following anterior cervical spine surgery is a relatively rare occurrence. Prompt recognition and treatment of these injuries is critical to minimizing morbidity and mortality.

    2014-04-01

    Background Improved treatment and survival of patients with skull base tumors has made the assessment of quality-of-life (QoL) in this population increasingly important. This article provides a comprehensive systematic review pertaining to QoL assessment in adults undergoing anterior skull base surgery. Methods We performed a literature search using the electronic databases of Ovid Medline and Embase. Additional articles were identified through a search using the phrase anterior skull base. Further articles were sought through hand-searching relevant journals and reference lists of identified articles. Results Our search strategy identified 29 articles for inclusion in our systematic review, with considerable variation between studies in population characteristics, methodological design and quality, follow-up length, and outcome assessment. The most commonly used QoL tools were the Karnofsky Performance Status and the Anterior Skull Base Questionnaire. QoL following anterior skull base surgery appears to improve beyond preoperative levels in the months after surgery. For patients undergoing endoscopic skull base surgery, the gain in QoL appears to be greater and may manifest earlier, with no clear long-term deleterious effect on sinonasal outcomes compared with open surgery. Conclusions QoL after anterior skull base surgery in adults appears to improve within several months of surgery, but earlier and to a larger extent if the endoscopic approach is used. Given the relative paucity and heterogeneity of anterior skull base tumors, large-scale prospective multicentre studies utilizing valid and reliable multidimensional QoL tools are required. This may result in improved patient care, by understanding patients' needs better and facilitating the provision of reliable outcome data for clinical trials.

    retrospective review. to determine if Anterior/Posterior Combined approach spine surgery is associated with an increased risk of pulmonary embolism (PE) compared to Posterior Only approach surgery. combined anterior/posterior approach spine surgery is associated with a significantly increased risk for PE. However, it is uncertain if there is any difference in risk between combined approaches versus a posterior-only approach. a prospective cohort of patients who underwent anterior/posterior combined approach spine surgery from January 2002 to January 2006 was compared to a retrospective cohort of consecutive patients who underwent posterior only approach spine surgery from September2007 to September 2008. Patient demographics, medical history, body-mass indexes, type of surgery, length of surgery, transfusions, and instrumented vertebral levels were collected from hospital and office records. Hospital records were used to identify patients who developed PE based on diagnosis by spiral CT scan. CT scans were only performed when a patient's clinical picture raised suspicion of PE. Fisher exact test for significance, χ test and odds ratios were used for analysis. a total of 119 patients were included in the study: 63 patients underwent posterior approach spine surgery and 66 patients underwent combined anterior/posterior approach surgery. One patient (1.6%) developed PE after posterior approach surgery while 5 patients (7.5%) developed PE in the combined approach group. Those undergoing combined approaches were 5.08 times more likely to suffer from PE, but this increase was not significant (P = 0.208). Overall, increased risk for PE was associated with the number of levels fused (P = 0.006), total blood loss (P = 0.029), and number of units transfused (P = 0.030). The combined approach was associated with older age (P spine surgery is associated with an increased risk for pulmonary embolism compared to posterior only approaches.

A total of 86 patients with multi-segmental cervical spondylosis were treated by anterior cervical surgery procedure. Among them, 62 and 24 cases were involved in three and four gap, respectively. Each patient underwent the surgery of long or segmented anterior cervical decompression and fixation. Preoperative and postoperative cervical curvature change, internal fixation stability, fusion rate and nerve function were evaluated. All patients were successfully completed the operation, segmented surgery showed better cervical lordosis recovery, but there were no significant difference between long and segmented anterior cervical surgery in blood loss and recovery of neurological function (P> 0.05). The segmented anterior cervical surgery has advantages in the treatment of multisegmental cervical spondylosis.

    PURPOSE: To study changes in anterior segment morphometry after uneventful phacoemulsification cataract surgery, and to investigate whether there is a relationship between any observed changes and intraocular pressure (IOP) reduction after the procedure. METHODS: The anterior chamber depth (ACD), anterior chamber volume (ACV), anterior chamber angle (ACA), central corneal thickness (CCT), and IOP were measured in 101 non-glaucomatous eyes before and after uneventful phacoemulsification cataract surgery. RESULTS: After cataract surgery, the mean ACD, ACV, and ACA values increased by 1.08 mm, 54.4 mm(3), and 13.1 degrees , respectively, and the mean IOP (corrected for CCT) decreased by 3.2 mm Hg. The predictive value of a previously described index (preoperative ACD\\/preoperative IOP (corrected for CCT) or CPD ratio) for IOP (corrected for CCT) reduction after cataract surgery was confirmed, reflected in an r(2) value of 23.3% between these two parameters (P<0.001). Other indices predictive of IOP reduction after cataract surgery were also identified, including preoperative IOP\\/preoperative ACV and preoperative IOP\\/preoperative ACA, reflected in r(2) values of 13.7 and 13.7%, respectively (P<0.001 and P<0.001, respectively). CONCLUSIONS: Our study confirms the predictive value of the CPD ratio for IOP reduction after cataract surgery, and may contribute to the decision-making process in patients with glaucoma or ocular hypertension. Furthermore, two novel indices of preoperative parameters that are predictive for IOP reduction after cataract surgery were identified, and enhance our understanding of the mechanisms underlying IOP changes after this procedure.

METHODS: Subjects were randomly assigned, preoperatively, to the small intestine submucosa graft (n = 29 or traditional colporrhaphy (n = 27 treatment group. Postoperative outcomes were analyzed at 12 months. The Female Sexual Function Index questionnaire was used to assess sexual function. Data were compared with independent samples or a paired Student's t-test. RESULTS: In the small intestine submucosa group, the total mean Female Sexual Function Index score increased from 15.5±7.2 to 24.4±7.5 (p<0.001. In the traditional colporrhaphy group, the total mean Female Sexual Function Index score increased from 15.3±6.8 to 24.2±7.0 (p<0.001. Improvements were noted in the domains of desire, arousal, lubrication, orgasm, satisfaction, and pain. There were no differences between the two groups at the 12-month follow-up. CONCLUSIONS: Small intestine submucosa repair and traditional colporrhaphy both improved sexual function postoperatively. However, no differences were observed between the two techniques.

Tertiary referral center. In 12 patients with AN, persistent cerebellar dysfunction developed after AN removal. Each case demonstrated abnormality in the ipsilateral cerebellar peduncle on postoperative magnetic resonance imaging. Cerebellar function and ambulatory status over the first postoperative year. On magnetic resonance imaging scans, the extent of cerebellar peduncle infarcts was variable. It ranged from focal brain injury (2 cm) spanning the full thickness of the peduncle. Peduncular infarcts were associated with large tumor size (average 3.8 cm, range 2.0-5.5 cm diameter). The long-term functional outcomes (>1 yr) varied. Dysmetria was unchanged or improved in over half of the patients (6 of 11 patients). Gait recovered to normal or to preoperative levels in 5 patients. In the 6 patients with persistent impaired mobility, 2 had mild gait disturbance, 3 required regular use of a cane, and 1 has been dependent on a walker. One patient had sustained mild motor weakness. Three of 11 patients remained dependent on others for activities of daily living. Peduncle injury most likely stems from interruption of distal branches of the anterior inferior cerebellar artery (AICA). These small vessels are intimately related to the capsule of the tumor and may supply both the neoplasm and the brain parenchyma. It has long been recognized that interruption of the proximal segment of the AICA results in severe injury to the pons, with devastating neurologic sequelae. A limited AICA syndrome caused by loss of its distal ramifications seems a more plausible explanation for peduncular infarction than either venous insufficiency or direct surgical trauma.

    Full Text Available A 22-year-old man presented to our ophthalmology department with photophobia. On ophthalmic examination, iridodialysis secondary to blunt trauma that occurred 5 years ago was diagnosed. During iridodialysis repair surgery, long curved double-armed needle of 10-0 polypropylene suture (PC-9 inserted into the 19 gauge side port turned down inadvertently by its own weight, resulting in crystalline lens anterior capsule perforation. Postoperative clinical observation revealed no lens opacification affecting visual acuity. This case report showed that lens aspiration surgery should be postponed if the capsule injury is small.(Turk J Ophthalmol 2013; 43: 61-3

    To evaluate the anterior cruciate ligament graft failure rate in a population of 1376 patients submitted to single-bundle anterior cruciate ligament reconstruction procedure. It was hypothesized that the younger the patient, the greater the chance of a new anterior cruciate ligament graft ligament injury. A retrospective chart review was performed on patients who had SB anterior cruciate ligament reconstruction between the years, 2001 and 2016, with a minimum post-operative follow-up period of 6 months. The patient population was divided into three groups, according to age: group 1-under 16 years old; group 2-between 16 and 18 years old; and group 3-older than 18 years old. Data collected included sex, laterality and graft choice data. In group 1 (under 16 years old), there were 61 primary ACL surgeries performed and 15 (24.6%) revision ACL surgeries. In group 2 (between 16 and 18 years old), there was 57 primary ACL procedures, of which 10 (17.5%) were revisions. In the group 3 (older than 18 years of age), 1258 surgeries were done with 116 (9.2%) revisions. The rate of ACL revision surgery in patients under 16 years of age was significantly higher than that found in patients older than 18 years old. When compared to the population between 16 and 18 years old, there were a higher number of failure cases, however, statistically non-significant. IV.

    Anterior cervical spine procedures have been associated with satisfactory outcomes. However, the occurrence of troublesome complications, although uncommon, needs to be taken into consideration. The purpose of our study was to assess the actual incidence of anterior cervical spine procedure-associated complications and identify any predisposing factors. A total of 114 patients undergoing anterior cervical procedures over a 6-year period were included in our retrospective, case-control study. The diagnosis was cervical radiculopathy, and/or myelopathy due to degenerative disc disease, cervical spondylosis, or traumatic cervical spine injury. All our participants underwent surgical treatment, and complications were recorded. The most commonly performed procedure (79%) was anterior cervical discectomy and fusion (ACDF). Fourteen patients (12.3%) underwent anterior cervical corpectomy and interbody fusion, seven (6.1%) ACDF with plating, two (1.7%) odontoid screw fixation, and one anterior removal of osteophytes for severe Forestier's disease. Mean follow-up time was 42.5 months (range, 6-78 months). The overall complication rate was 13.2%. Specifically, we encountered adjacent intervertebral disc degeneration in 2.7% of our cases, dysphagia in 1.7%, postoperative soft tissue swelling and hematoma in 1.7%, and dural penetration in 1.7%. Additionally, esophageal perforation was observed in 0.9%, aggravation of preexisting myelopathy in 0.9%, symptomatic recurrent laryngeal nerve palsy in 0.9%, mechanical failure in 0.9%, and superficial wound infection in 0.9%. In the vast majority anterior cervical spine surgery-associated complications are minor, requiring no further intervention. Awareness, early recognition, and appropriate management, are of paramount importance for improving the patients' overall functional outcome.

    A retrospective multicenter case-series study; case report and review of the literature. The anatomy and function of the superior laryngeal nerve (SLN) are well described; however, the consequences of SLN injury remain variable and poorly defined. The prevalence of SLN injury as a consequence of cervical spine surgery is difficult to discern as its clinical manifestations are often inconstant and frequently of a subclinical degree. A multicenter study was performed to better delineate the risk factors, prevalence, and outcomes of SLN injury. A retrospective multicenter case-series study involving 21 high-volume surgical centers from the AO Spine North America Clinical Research Network. Medical records for 17 625 patients who received subaxial cervical spine surgery from 2005 to 2011 were reviewed to identify occurrence of 21 predefined treatment complications. Descriptive statistics were provided for baseline patient characteristics. A retrospective review of the neurosurgical literature on SLN injury was also performed. A total of 8887 patients who underwent anterior cervical spine surgery at the participating institutions were screened, and 1 case of SLN palsy was identified. The prevalence ranged from 0% to 1.25% across all centers. The patient identified underwent a C4 corpectomy. The SLN injury was identified after the patient demonstrated difficulty swallowing postoperatively. He underwent placement of a percutaneous gastrostomy tube and his SLN palsy resolved by 6 weeks. This multicenter study demonstrates that identification of SLN injury occurs very infrequently. Symptomatic SLN injury is an exceedingly rare complication of anterior cervical spine surgery. The SLN is particularly vulnerable when exposing the more rostral levels of the cervical spine. Careful dissection and retraction of the longus coli may decrease the risk of SLN injury during anterior cervical surgery.

    Male genital dysfunction was recognized as a complication following anterior approach lumbar surgery. Disruption of efferent sympathetic pathways such as the abdominal aortic plexus (AAP) and superior hypogastric plexus (SHP) which lied pre-abdominal aorta and iliac artery had been thought as the main reason. Though there were some clinical reports of retrograde ejaculation, the applied anatomic study of the autonomic nerve anterior to the lumbar was little. The purpose was to find out a lumbar surgery approach which was ejaculation preservation through the detailed study of the anatomy and histology observation of the autonomic nerve anterior to the lumbar vertebrae. The lumbar region of ten male cadavers was dissected and analyzed. We investigated the relationship between the peritoneum and abdominal aorta, iliac artery and sacral promontory fascia, as well as the trend and distribution of the autonomic nerve and SHP anterior to the L5-S1. We also observed the distribution of autonomic nerve at retroperitoneum through hematoxylin and eosin (HE)-stained tissues pre-aorta, para-aorta, and pre-vertebrae sacrales. Superior hypogastric plexus, which deviated to left, located in a triangle formed by the common iliac arteries and its bilateral branches, its truck sited anterior to the lumbarsacral space in seven cases (70%), and anterior to sacrum in three cases (30%); at the aortic bifurcation, SHP strided over left iliac artery from left-hand side, then located in front of sacrum in four cases (40%), and sifted to the left at the lumbar sacral promontory in six cases (60%); from both anatomic and histological view, the autonomic nerve plexus lying in an fascia layer of retroperitoneum. At the anterior approach lumbar surgery of trans-peritoneum, we should choose the right-hand side incision; the SHP should be pushed aside carefully from right to left along intervertebral disc. The accurate surgical plane was at the deeper layer of autonomical nerve fascia; we also

    Patient satisfaction is becoming an increasing common proxy for surgical quality; however, the correlation between patient satisfaction and surgical outcomes 2 and 5 years after anterior cervical surgery has not been evaluated. The study aimed to determine if patient satisfaction is predicted by improvement in patient-reported outcomes (PRO) 2 and 5 years after anterior cervical spine surgery. This is a retrospective analysis of prospectively collected data. The sample included patients enrolled in the Food and Drug Administration investigational device exemption clinical trial comparing total disc replacement with Mobi-C cervical artificial disc and anterior cervical discectomy and fusion. The outcome measures were visual analog scale (VAS) neck pain score, Neck Disability Index (NDI), and Short-Form 12-Item scores, as well as patient satisfaction. Receiver operating characteristic curves were used to determine if improvement in different PRO metrics can accurately identify patient satisfaction. Additionally, a logistic regression analysis was performed on the results at 24 months and 60 months to identify independent predictors of patient satisfaction. This research was supported by LDR (Zimmer Biomet) 13785 Research Boulevard - Suite 200 Austin, TX 78750. Data were available for 512 patients at 60 months. At 24 months postoperatively, NDI score improvement (area under the curve [AUC]=0.806), absolute NDI score (AUC=0.823), and absolute VAS neck pain score (AUC=0.808) were all excellent predictors of patient satisfaction. At 60 months postoperatively, NDI score improvement (AUC=0.815), absolute NDI score (AUC=0.839), VAS neck pain score improvement (AUC=0.803), and absolute VAS neck pain score (AUC=0.861) were all excellent predictors of patient satisfaction. In patients undergoing one- and two-level anterior cervical spine surgery, between 2 and 5 years postoperatively, patient satisfaction is significantly predicted by PROs, including the VAS neck score and the

    Prospective cohort study. Prospectively compare patient-reported as well as clinical and radiologic outcomes after anterior or posterior surgery for right thoracic adolescent idiopathic scoliosis (AIS) in a single center by the same surgeons. Anterior and posterior spinal instrumentation and arthrodesis are both well-established treatments of thoracic AIS. The majority of studies comparing the 2 approaches have focused on radiographic outcomes. There remains a paucity of prospectively gathered patient-reported outcomes comparing surgical approaches. Forty-two consecutive patients with right thoracic AIS were treated in a single center by one of 2 surgeons with either anterior (n=18) or posterior (n=24) approaches and followed up for over 2 years. Radiographic, clinical, and patient-reported outcomes of the Modified Scoliosis Research Society Outcome Instrument were gathered and analyzed by an independent surgeon. Patients reported significant improvements in all areas of the Modified Scoliosis Research Society Outcome Instrument, especially pain and self-image domains. There were no significant differences in the degree of improvement in any domains between the groups. Posterior and anterior surgery corrected rib hump by 53% and 61%, respectively (P=0.4). The Main thoracic curve Cobb angle was corrected from 69 to 26 degrees (62%) by posterior surgery and 61 to 23 degrees (64%) by anterior surgery (P=0.6). Posterior surgery significantly reduced kyphosis and lumbosacral lordosis. Anterior surgery had no overall affect of sagittal alignment but seemed able to correct those hypokyphotic preoperatively. Complications differed and were largely approach-related--intrathoracic in anterior and wound-related in posterior surgery. Patients with right thoracic AIS of differing curve types but otherwise similar preoperatively demonstrated that anterior and posterior surgery are largely equivalent. Patient-reported outcomes are improved similarly by either approach. Both offer

    Three dimensional (3D) image guidance has been used to improve the safety of complex spine surgeries, but its use has been limited in anterior cervical spine approaches. Twenty-two patients underwent complex anterior cervical spine surgeries in which 3D image guidance provided intraoperative assistance with the dissection, decompression and implant placement. One of two paired systems, the BrainLAB (BrainLAB, Westchester, Illinois) system, or Stealth (Medtronic Inc., Littleton, Massachusetts) system was used for 3D image guidance in this study. Image guidance was able to reliably locate pertinent anatomical structures in complex anterior cervical spine surgery involving re-exploration, dissection around vertebral arteries or deformity correction. No complications occurred, and no patients required a revision anterior surgery. This technical note describes the setup and technique for the use of cone beam computed tomography (cbCT)-based, 3D image guidance in subaxial anterior cervical surgery. The authors have found this technique to be a useful adjunct in revision anterior cervical procedures, as well as anterior cervical procedures involving corpectomy or tumor removal.

    To describe our experience in treating esophageal and pharyngeal perforation after anterior cervical spine surgery. Six patients with esophageal injury and one patient with pharyngeal injury after anterior cervical spinal surgery, managed at our department between 2000 and 2015, were analyzed retrospectively. During the study period, 7 patients (6 male and 1 female; mean age, 45 years) presented with esophageal perforation. The original anterior cervical spinal surgery was performed due to trauma in 2 patients and because of a degenerative cervical disorder in 5. Early esophageal perforation was diagnosed in 2 patients, and delayed esophageal injury due to chronic irritation with the cervical implants was noted in 5. Three of the five delayed perforation cases were related to cervical instrument displacement. Two patients showed no definite signs of infection, whereas 5 patients had various symptoms, including fever, neck pain, odynophagia, neck swelling, and upper extremity weakness. Two patients with a large defect underwent surgical repair and three with minimal perforation due to chronic irritation from the implants underwent instrument removal without direct repair of defect. Two asymptomatic patients received no intervention. Six patients with infection completely recovered from esophageal injury after treatment for a mean duration of 5.2 weeks (range, 4-8 weeks). One patient died because of postoperative pneumonia and sepsis after implant removal. Esophageal and pharyngeal injury after cervical spinal surgery may occur either directly due to spinal trauma and vigorous intraoperative retraction or due to chronic irritation with cervical implants. In cases of perforation associated with infection, various surgical modalities, including primary closure and reinforcement with a flap, could be considered depending on factors such as esophageal defect size, infection severity, and timing of recognition of injury.

    Delphi Panel expert panel consensus and narrative literature review. To obtain expert consensus on best practices for patient selection and perioperative decision making for outpatient anterior cervical surgery (anterior cervical disc fusion (ACDF) and cervical total disc replacement (CTDR)). Spine surgery in ambulatory settings is becoming a preferred option for both patients and providers. The transition from traditional inpatient environments has been enabled by innovation in anesthesia protocols and surgical technique, as well as favorable economics. Studies have demonstrated that anterior cervical surgery (ACDF and CTDR) can be performed safely on an outpatient basis. However, practice guidelines and evidence-based protocols to inform best practices for the safe and efficient performance of these procedures in same-day, ambulatory settings are lacking. A panel of five neurosurgeons, three anesthesiologists, one orthopedic spine surgeon, and a registered nurse was convened to comprise a multidisciplinary expert panel. A three-round modified-Delphi method was used to generate best-practice statements. Predetermined consensus was set at 70% for each best-practice statement. A total of 94 consensus statements were reviewed by the panel. After three rounds of review, there was consensus for 83 best-practice statements, while 11 statements failed to achieve consensus. All statements within several perioperative categories (and subcategories) achieved consensus, including preoperative assessment (n = 8), home-care/follow-up (n = 2), second-stage recovery (n = 18), provider economics (n = 8), patient education (n = 14), discharge criteria (n = 4), and hypothermia prevention (n = 6). This study obtained expert-panel consensus on best practices for patient selection and perioperative decision making for outpatient anterior cervical surgery (ACDF/CTDR). Given a paucity of guidelines and a lack of established care pathways for ACDF/CTDR in same

    OBJECTIVE: Our objectives were to describe the preoperative mood levels and psychological readiness levels of patients undergoing primary reconstruction of the anterior cruciate ligament (ACL) and to examine differences between adolescent and adult sports medicine patients relative to psychological readiness for ACL surgery. DESIGN AND SETTING: Subjects prospectively completed assessments of preoperative mood and psychological readiness for ACL surgery and rehabilitation. SUBJECTS: The sample consisted of subjects (N = 121) involved, on average, in sport or exercise participation 12.5 h/wk (SD = 7.5); subgroups included adolescents (15-19 years of age, n = 67) and adults (>/=30 years of age, n = 32). MEASUREMENTS: Subjects preoperatively provided self-reported assessments of demographics, mood disturbances, 10 psychological processes of change (consciousness raising, dramatic relief, environmental reevaluation, social liberation, self-reevaluation, counterconditioning, helping relationships, reinforcement management, stimulus control, and self-liberation), decisional balance (pros versus cons of surgery), and self-efficacy. RESULTS: Relative to the first objective, subjects reported more pros than cons associated with surgery and relatively high levels of self-efficacy. Relative to the second objective, a significant main effect was noted (Wilks lambda = 0.58, P <.01), with 42% of the variance in the dependent variables being attributed to differences among adolescents as compared with adults. Follow-up analyses indicated that, as compared with adults, adolescents reported higher mood disturbances, more pros associated with surgery, and greater use of dramatic relief, environmental reevaluation, social liberation, helping relationships, and self-liberation. CONCLUSIONS: It may be advantageous to screen patients preoperatively relative to their psychological readiness for surgery and rehabilitation. Also, adolescents reported higher preoperative mood

    Full Text Available AIM: To investigate the change of anterior chamber angle morphology and intraocular pressure (IOP reduction after cataract surgery in patients with normal-tension glaucoma (NTG using swept-source optical coherence tomography (SS-OCT. METHODS: This prospective, comparative, observational study recruited patients into two groups. Group 1 was the control group including normal subjects except those with cataracts (cataract group, n=67 eyes of 67 patients, and group 2 was NTG group including patients who were diagnosed with NTG and cataracts (n=43 eyes of 43 patients, which were treated with phacoemulsification and intraocular lens implantation. Before surgery, and at postoperative 1 and 6mo, anterior chamber angles were evaluated by SS-OCT under dark conditions using three-dimensional angle analysis scan protocol. Angle opening distance (AOD, angle recess area (ARA, and trabecular-iris surface area (TISA at four quadrants (temporal, nasal, superior, and inferior were calculated automatically by SS-OCT, after the observer marked scleral spurs. RESULTS: A total of 106 patients (54 males and 52 females were enrolled in the study. Angle parameters, AOD, ARA, and TISA were increased after surgery in both groups. However, changes of angle parameters were only significant in group 2. In group 2, preoperative IOP was 13.2±2.9 mm Hg, and postoperative IOP at 1 and 6mo were 10.5±3.0 and 10.7±2.8 mm Hg, respectively. In group 1, preoperative IOP was 12.4±2.8 mm Hg, and postoperative IOP at 1 and 6mo were 11.6±2.5 and 12.0±2.8 mm Hg, respectively. After cataract surgery, angle parameters changed significantly while IOP significantly reduced and was maintained in group 2 (P<0.001. The changes in angle parameters (ΔAOD500, ΔTISA500 at temporal; ΔAOD500, ΔARA500 at nasal were linearly correlated with postoperative IOP changes. CONCLUSION: Cataract surgery may have improved anterior chamber angle parameters and decreased IOP in NTG patients.

    Full Text Available Background Context. Percutaneous balloon kyphoplasty is an established minimally invasive technique to treat painful vertebral compression fractures, especially in the context of osteoporosis with a minor complication rate. Purpose. To describe the heparin anticoagulation treatment of paraplegia following balloon kyphoplasty. Study Design. We report the first case of an anterior spinal artery syndrome with a postoperative reversible paraplegia following a minimally invasive spine surgery (balloon kyphoplasty without cement leakage. Methods. A 75-year-old female patient underwent balloon kyphoplasty for a fresh fracture of the first vertebra. Results. Postoperatively, the patient developed an acute anterior spinal artery syndrome with motor paraplegia of the lower extremities as well as loss of pain and temperature sensation with retained proprioception and vibratory sensation. Complete recovery occurred six hours after bolus therapy with 15.000 IU low-molecular heparin. Conclusion. Spine surgeons should consider vascular complications in patients with incomplete spinal cord syndromes after balloon kyphoplasty, not only after more invasive spine surgery. High-dose low-molecular heparin might help to reperfuse the Adamkiewicz artery.

    Up to two-thirds of athletes may not return to their preinjury level of sport by 12 months after anterior cruciate ligament (ACL) reconstruction surgery, despite being physically recovered. This has led to questions about what other factors may influence return to sport. To determine whether psychological factors predicted return to preinjury level of sport by 12 months after ACL reconstruction surgery. Case control study; Level of evidence, 3. Recreational and competitive-level athletes seen at a private orthopaedic clinic with an ACL injury were consecutively recruited. The primary outcome was return to the preinjury level of sports participation. The psychological factors evaluated were psychological readiness to return to sport, fear of reinjury, mood, emotions, sport locus of control, and recovery expectations. Participants were followed up preoperatively and at 4 and 12 months postoperatively. In total, 187 athletes participated. At 12 months, 56 athletes (31%) had returned to their preinjury level of sports participation. Significant independent contributions to returning to the preinjury level by 12 months after surgery were made by psychological readiness to return to sport, fear of reinjury, sport locus of control, and the athlete's estimate of the number of months it would take to return to sport, as measured preoperatively (χ(2) 2 = 18.3, P Psychological responses before surgery and in early recovery were associated with returning to preinjury level of sport at 12 months, suggesting that attention to psychological recovery in addition to physical recovery after ACL injury and reconstruction surgery may be warranted. Clinical screening for maladaptive psychological responses in athletes before and soon after surgery may help clinicians identify athletes at risk of not returning to their preinjury level of sport by 12 months.

    Full Text Available Context : Pediatric cataract surgery is traditionally done with the aid of high-molecular-weight viscoelastics which are expensive. It needs to be determined if low-cost substitutes are just as successful. Aims : The study aims to determine the success rates for anterior and posterior capsulorrhexis and intraocular lens (IOL implantation in the bag for pediatric cataract surgery performed with the aid of a low-molecular-weight viscoelastic. Settings and Design : Nonrandomized observational study. Materials and Methods: Children less than 6 years of age who underwent cataract surgery with IOL implantation in the period May 2008-May 2009 were included. The surgeries were done by pediatric ophthalmology fellows. A standard procedure of anterior capsulorrhexis, lens aspiration with primary posterior capsulorrhexis, anterior vitrectomy, and IOL implantation was followed. Three parameters were studied: successful completion of anterior and posterior capsulorrhexis and IOL implantation in the bag. Results: 33 eyes of 28 children were studied. The success rate for completion was 66.7% and 88.2 % for anterior and posterior capsulorrhexis, respectively. IOL implantation in the bag was successful in 87.9%. Conclusions: 2% hydroxypropylmethylcellulose is a viable low-cost alternative to more expensive options similar to high-molecular-weight viscoelastics. This is of great relevance to hospitals in developing countries.

    We evaluated the health-related quality of life (QOL) of patients undergoing anterior skull base tumor resection. The Anterior Skull Base Surgery QOL questionnaire, a disease-specific multidimensional instrument dedicated to this population, was used to collect and prospectively analyze demographic, medical, and QOL data on 48 patients. Thirty-nine patients completed the questionnaire preoperatively and at 6 and 12 months postoperatively. Seventeen patients (44%) had malignant histology and 22 (56%) had benign tumors. The overall QOL score decreased significantly at 6 months postoperatively (p base tumor resection returns to baseline by 1 year after surgery. Histology and radiotherapy are significant predictors of health-related QOL in this population.

    Intraoperative use of the mobile Siremobil Iso-C3D C-arm (Siemens AG, Medical Solutions, Erlangen) considerably improves the information available during cervical spine surgery. We report our experiences with the Iso-C3D fluoroscopic unit during anterior decompressive surgery of the cervical spine. We used the mobile Siremobil Iso-C3D C-arm during decompressive cervical spine surgery. The study included 25 patients (22 males, 3 females) with degenerative cervical stenosis. Mean age was 55.9 years (42-73 years). Eighteen patients were surgically treated for one-level, six for two-level and one for three-level disease. Intraoperative 3D imaging was performed to evaluate the extent of bony decompression and to assist correct positioning of the cages when the surgeon believed that sufficient decompression had been achieved. Visualization of the extent of bone removal was good in all patients. In 3 patients, insufficient bony decompression with persisting dorsal osteophytic spurs was noticed on sagittal and axial images. In these patients, surgery had to be continued. Successful decompression was proved thereafter by a second scan. The quality of the images of the cervical spine was sufficient, although slightly inferior to that of a CT scan. The Siremobil Iso-C3D provides intraoperative 3D images of bony structures of the cervical spine. Although the imagine quality is inferior to that of a CT, in our series surgical revisions could be avoided in 12.5% of the patients on the basis of these intraoperative images of incomplete bony decompression. This means a reduction of additional costs which would arise with surgical revision.

    Anterior cruciate ligament (ACL) injuries occur most commonly in individuals between 18 and 29 years of age and are strongly correlated with sporting activity, with female athletes being at higher risk of ACL rupture than their male counterparts. ACL reconstruction is one of the most frequently performed procedures in orthopaedic surgery, having a reported incidence of 85 per 100,000 head of population in the at-risk age group. Subsequent graft failure is most commonly caused by recurrent trauma, followed by tunnel malpositioning, although the choice of graft type does not appear to affect outcome. The Danish ACL registry reported that ACL revisions accounted for 7.5% of all ACL reconstruction surgery performed between 2005 and 2008. Revision of ACL reconstruction is recognized to carry a worse outcome than primary reconstruction. Preoperative imaging has become a crucial part of surgical planning in these patients, with great reliance placed on computed tomography (CT). The radiologist should be able to recognize the types of primary repair and must be able to assess for the complications of primary surgery, such as tunnel malpositioning, tunnel widening, and fixation device failure. Revision is commonly a two-stage procedure with bone grafting of the tunnels prior to the definitive ligament repair. The radiologist should be able to asses for adequate bone graft incorporation. The purpose of this article is to present a review of the use of CT in the management of ACL revision surgery with examples of commonly used fixation devices; complications, such as tunnel widening and tunnel malpositioning; and bone graft incorporation

    The International Council of Ophthalmology (ICO) is currently developing a series of standardized, internationally validated, teaching tools for key ophthalmic surgical procedures called the Ophthalmology Surgical Competency Assessment Rubrics (OSCARs). This study aims to develop an OSCAR for anterior approach ptosis surgery. An international panel of content experts, representing Australia, India, Iran, Italy, Turkey, UK, and the USA was established and worked to develop the rubric using a range of online collaboration tools. The team used the standardised OSCAR template as a baseline, developing explicit behavioural descriptors (the behaviour and performance expected for each step) that were reviewed and modified with successive models. Learners were scored a modified 4-point Dreyfus scale of skill acquisition (novice, beginner, advanced beginner, competent) with the removal of the expert domain. The final OSCAR ptosis tool was developed in alignment with the ICO-OSCAR standard. Seventeen agreed and weighted stems were produced. Domains such as communication and postoperative complications were removed from this rubric as they are evaluated in other spheres of residency training. Specific comments with regard to the parameters and wording were incorporated to formulate the final rubric, which was internationally agreed and demonstrated face and content validity. The OSCAR for anterior approach ptosis is skill and behaviour-based, has ICO agreed standards for assessment and provides learners with specific targets for improvement. Although the OSCAR ptosis tool has face and content validity, further development could better elucidate its precise role.

Tyndallization and fibrin fibers were positive in all eyes. In four eyes, hypopyon formation developed. These reactions diminished on the third day and fully resolved 1 week after the operations with the use of intensive topical steroid and mydriatic therapy. To determine the etiology of TASS, infusion fluid, viscoelastics, and intracameral antibiotic agent were changed respectively. After changing intracameral antibiotic agent from cefuroxime axetile to moxifloxacin no new cases of TASS were diagnosed.Conclusion: All agents injected into the anterior chamber can cause TASS. Ophthalmologists and operating room staff need to pay careful attention to all drugs and irrigating solutions.Keywords: phacoemulsification, fibrin reaction, drug toxicity

    The purpose of the study was to evaluate the position of the subscapular nerves relative to surgical landmarks during exposure and to analyze the pattern of innervation of the subscapularis to avoid injury during anterior shoulder surgery. 20 embalmed human cadaveric shoulder specimens were used in the study. The muscular insertions of the subscapular nerves were marked and their closest branches to the musculotendinous junction and the coracoid process were measured in horizontal and vertical distances. In addition, the innervation pattern of each specimen was documented. 14/20 specimens showed an innervation of the subscapularis with an upper, middle and lower subscapular nerve branch. Even though the nerve branches were in average more than 2 cm medial to the musculotendinous junction, minimal distances of 1.1-1.3 cm were found. The mean vertical distance as measured from the medial base of the coracoid to the nerve innervation point into the muscle was 0.7 cm for the upper nerve branch, 2.2 cm for the middle nerve branch and 4.4 cm for the lower nerve branch. The subscapularis has a variable nerve supply, which increases the risk of muscle denervation during open shoulder surgery. Dissection or release should be avoided at the anterior aspect of the subscapularis muscle more than 1 cm medial to the musculotendinous junction. In approaches with a horizontal incision of the subscapularis, splitting should be performed at a vertical distance of 3.2-3.6 cm to the coracoid base to avoid iatrogenic subscapular nerve injuries.

    Toxic anterior segment syndrome (TASS), a complication of cataract surgery, is a sterile inflammation of the anterior chamber of the eye. An outbreak of TASS was recognized at an outpatient surgical center and its affiliated hospital in December 2002. Medical records of patients who underwent cataract surgery during the outbreak were reviewed, and surgical team members who participated in the operations were interviewed. Potential causes of TASS were identified and eliminated. Feedwater from autoclave steam generators and steam condensates were analyzed by use of spectroscopy and ion chromatography. During the outbreak, 8 (38%) of 21 cataract operations were complicated by TASS, compared with 2 (0.07%) of 2,713 operations performed from January 1996 through November 2002. Results of an initial investigation suggested that cataract surgical equipment may have been contaminated by suboptimal equipment reprocessing or as a result of personnel changes. The frequency of TASS decreased (1 of 44 cataract operations) after reassignment of personnel and revision of equipment reprocessing procedures. Further investigation identified the presence of impurities (eg, sulfates, copper, zinc, nickel, and silica) in autoclave steam moisture, which was attributed to improper maintenance of the autoclave steam generator in the outpatient surgical center. When impurities in autoclave steam moisture were eliminated, no cases of TASS were observed after more than 1,000 cataract operations. Suboptimal reprocessing of cataract surgical equipment may evolve over time in busy, multidisciplinary surgical centers. Clinically significant contamination of surgical equipment may result from inappropriate maintenance of steam sterilization systems. Standardization of protocols for reprocessing of cataract surgical equipment may prevent outbreaks of TASS and may be of assistance during outbreak investigations.

    Anterior inferior cerebellar artery (AICA) aneurysms are very rare. We carried out four direct operations for AICA aneurysms including two distal AICA aneurysms using lateral suboccipital retrosigmoid approaches (LSRA). We successfully performed the clipping by LSRA. but hearing loss occurred except in one of our cases which involved a chronic term operation in in our cases, In a 72 years old female with a ruptured dissecting aneurysm of the AICA anterior pontine segment, we performed the OA-PICA anastomosis first because of its being an AICA-PICA type, and then we continued to carry out the trapping operation of dissecting artery on day 0. She left our hospital cheerfully but hearing loss persisted on the operated side. Four examples of the dissecting aneurysm of AICA anterior pontine segment have been reported, but only our case involved the trapping with revascularization in acute stage. At the moment, there is no clinical or useful classification for distal AICA aneurysm because it is extremely rare. We will now propose a new classification. This classification is divided into two groups, (1) P (pons) -group and (2) C (cerebellum) -group. The P-group consists of pA (AICA anterior pontine segment). pL (lateral branch on the pons to the meatal loop) and pM (medial branch on the pons). C-group consists of m-loop (meatal loop), cL (lateral branch post meatal loop) and cM (medial branch on the cerebellum). From results of case reports (75 distal AICA aneurysms), we found that pA: 5 (6.7%), pL: 2 (2.8%), pM: 0, m-loop: 54 (72%), cL: 8 (11%), cM: 6 (8.3%). The followings factors were also found. (1) Occlusion of the parent artery of P-group without revascularization of peripheral circulation may entail the risk of death. (2) On the other hand, as for the C-group, the parent artery was able to be occluded without severe consequences, but hearing loss and/or cerebellar infarction occurred. We believe that this classification is simple and very useful for therapeutic

    Full Text Available A 59-year-old man with a history of longstanding systemic hypotension developed asymmetric non-arteritic anterior ischemic optic neuropathy (NAION apparently precipitated by bilateral sequential acute primary angle closure. NAION is very rarely reported in association with raised intraocular pressure. In contrast to optical coherence tomography, the failure of scanning laser polarimetry to detect axonal swelling was another interesting finding. Possible reasoning for these observations is discussed.

    Full Text Available AIM: To analyze and compare five different variables over one year follow-up (1wk, 1, 3, 6 and 12mo: anterior capsule (AC, and posterior capsule (PC area densitometry values, AC and PC linear densitometry values, and AC opening area reduction ratio after femtosecond laser-assisted cataract surgery. METHODS: This was a prospective comparative study. Seventy-one patients underwent femtosecond laser-assisted cataract surgery on single eye between June 2014 and December 2015. A 5.0 mm diameter laser assisted anterior capsulotomy was performed on all eyes. In every post-surgery evaluation, AC opacificaction (ACO and PC opacification (PCO density levels were provided by Oculus Pentacam®HR using area and linear densitometry methods. Digital images were captured with a slit-lamp Topcon photographic camera and IMAGEnet® 5 software. The AC opening area on the digital images was measured using the Sketchandcalc area calculator and converted to reduction ratio levels. RESULTS: Using Pearson correlation coefficient (PCC, we found no correlation (r=-0.091, P=0.46 in the twelfth month assessment between the evolution of ACO area densitometry values and PCO area densitometry values considered as independent variables. We found no correlation, using PCC (r=-0.096, P=0.43 between the evolution of ACO linear densitometry values and PCO linear densitometry values, in the twelfth month visit, working both as independent variables. AC linear densitometry levels and AC area densitometry levels continued to grow strongly from sixth to twelfth months. Analysis of the values of AC opening area reduction ratio (1wk, 1, 3, 6, 12mo revealed statistically significant differences between the values of successive examinations but the magnitude of the change decreased. In the final period of monitoring between six and twelve months the magnitude of change was low. CONCLUSION: Our results show strong increases of Scheimpflug ACO densitometry values from the sixth to the

    The purpose of this observational study of social media in sports medicine was to investigate and analyze the presence and shared content of anterior cruciate ligament (ACL) patients, sports surgeons, and top orthopaedic hospitals on popular social media streams. A search of 2 public domains (Instagram and Twitter) was performed over a 6-month period. ACL surgery ("#aclsurgery") was selected for the Instagram-based patient analysis after exclusion of veterinary ACL operations. A binary scoring system was used for media format, time (preoperatively or postoperatively), perioperative period (within 1 week of surgery), tone (positive or negative), return-to-work reference, return-to-play reference, rehabilitation reference, surgical-site reference, satisfaction reference, and dissatisfaction reference; perspective of the media was noted as well. A sample of 97 National Football League team surgeons was used for analysis of physician use in social media outlets and quantified by the number of posts. Hospital analysis categorized a sample of the top 50 orthopaedic hospitals by average number of posts and monthly posting rates with regard to orthopaedics, research, education, and personnel focus. In the patient analysis, 3,145 public posts of human subjects were shared on Instagram. Of these, 92% were personal recovery stories, with an emphasis on postoperative photographs (93%) with a positive tone (88%) more than 1 week after surgery (73%). Posts focused on surgical site (25%), return to play (30%), and postoperative rehabilitation (37%). Of the physicians, 16% had Twitter accounts, with an average of 94 posts per surgeon; none had Instagram accounts. Of the hospitals, 96% had Twitter accounts and 32% had Instagram accounts. Most of the hospital-based Instagram content in the sample was centered on patients or celebrities. Orthopaedic surgery has a large social media presence. Patients emphasize wound appearance, the rehabilitation process, and return to play

    Iatrogenic vertebral artery injury (VAI) during anterior cervical surgery is rare but potentially catastrophic. Causes, presentation, diagnosis, management, prognosis, and prevention of VAI were reviewed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. English language studies and case reports published from 1980 to 2017 were retrieved. Data on diagnosis, surgical procedures and approach, site and cause of VAI, management, outcomes, and vertebral artery (VA) status were extracted. In 25 articles including 54 patients, VAI was diagnosed during or after surgery commonly indicated for cervical degenerative diseases (64%), tumors (14%), and trauma (9%). The incidence of VAI for each side was similar regardless of approach. Common presentations were unexpected copious surgical bleeding, delayed hemorrhage of pseudoaneurysm with neck swelling, dyspnea, hypotension, and cervical bruits caused by arteriovenous fistula. Causes included drilling (61%), instrumentation (16%), and soft tissue retraction (8%). Direct exposure or angiography confirmed VAI. Ten patients had VA anomalies; collateral status was verified in 9 before definitive treatment. Tamponade was adopted for urgent hemostasis in most cases but with a high incidence of pseudoaneurysm (48%). Unknown VA status increased occlusion risk and neurologic sequelae (41%). VA repair and stent placement had excellent outcomes. Extensive lateral decompression, loss of landmarks, and anatomic variations or pathologic status of VA increased VAI risk. Evaluation of collateral vessels before definitive treatment helped determine appropriate management and avoid neurologic sequelae. Tamponade was not recommended as definitive treatment. Meticulous preoperative evaluation, cautious intraoperative manipulation, and real-time radiographic guidance reduced VAI risk. Copyright © 2017 Elsevier Inc. All rights reserved.

    Unusual anatomical segmentectomies are technically demanding procedures that require a deep knowledge of intralobar anatomy and surgical skill. In the other hand, these procedures preserve more normal lung parenchyma for lesions located in specific anatomical segments, and are indicated for benign lesions, metastasis and also early stage adenocarcinomas without nodal involvement. A 32-year-old woman was diagnosed of a benign pneumocytoma in the anterior segment of the left-lower lobe (S8, LLL), so we performed a single-incision video-assisted thoracoscopic surgery (SI-VATS) anatomical S8 segmentectomy in 140 minutes under intercostal block. There were no intraoperative neither postoperative complications, the chest tube was removed at 24 hours and the patient discharged at 5 th postoperative day with low pain on the visual analogue scale (VAS). Final pathologic exam reported a benign sclerosant pneumocytoma with free margins. The patient has recovered her normal activities at 3 months completely with radiological normal controls at 1 and 3 months.

    The present study aimed to re-evaluate the incidence of early dysphonia after anterior cervical spine surgery (ACSS) and to determine the related risk factors. Patients underwent ACSS between January 2011 and December 2013 at two sites were identified retrospectively from hospital's patient databases. A total of 233 cases were included in this study. Dysphonia developed 1 month postoperatively was recorded. Follow-up was conducted in all positive-response patients. Those reporting severe or persistent voice symptoms were referred to otolaryngologists for further assessments and (or) treatments. Pre and intraoperative factors were collected to determine their relationships with dysphonia one month postoperatively. 45 patients developed dysphonia at one month, including 23 males and 22 females, yielding to an incidence of 19.3%. 34 cases resolved themselves in 3 months, leaving the remaining 11 patients considered to be severe or persistent cases. However, 10 of them recovered spontaneously in the next 9 months, while the last case received vocal cord medialization and returned to almost normal speech function at 18 months. In univariate analysis, only approaching level involving C6-C7 or (and) C7-T1 was significantly associated with postoperative dysphonia (Pdysphonia following ACSS was relatively high and approaching at lower cervical levels was an independent predictive factor.

    Eighty-two patients operated on in our Department between 1989 and 1995 with an anterior cervical approach for soft and hard cervical disc herniations and cervical stenosis were included in this study. In 41 cases a heterologous intersomatic bovine graft (Surgibone) was used. Another 41 patients underwent surgery with a biocompatible osteoconductive polymer (BOP) as intervertebral graft. Both groups were retrospectively reviewed and compared with the objectives of evaluating the biodynamic behaviour of the grafts in the intersomatic space, the complications which appeared (specially those related to the grafts), the bone fusion rate achieved and the clinical outcome of the patients. The results of our study show that the BOP group presented a higher tendency to intersomatic space collapse 6 months after discectomy. There were no differences in the general surgical complications between both groups, but those related directly to the graft were significantly higher in the BOP group. The vast majority of the graft complications recorded had no clinical correlation. Without a strict radiological follow-up such complications would never have been discovered. Bone fusion in the BOP group was significantly slower and worse. Finally, the clinical outcome in both groups did not show any significant difference.

    We investigate the anatomy of the lumbosacral anterior great vessels using computer tomography (CT) angiography before L5/S1 anterior interbody surgery. Sixty-two adult patients were selected. The location of the abdominal aortic bifurcation and common iliac venous confluence in the lumbar vertebrae and the anatomic parameters of the iliac vascular space (e.g., distances from the included angle vertex of the iliac vascular space to the median sagittal plane and to the inferior boundary of L5 and distances between the left and right iliac vessels on the inferior boundary of L5 and on the superior boundary of S1) were analysed. Overall, 67.73% of the 62 cases had an abdominal aortic bifurcation located at L4 and L4/5 intervertebral disc; 61.29%, the common iliac venous confluence located at L5. The four distances mentioned above were 0.98 cm ± 0.38 cm, 2.01 cm ± 1.26 cm, 3.11 cm ± 1.35 cm and 4.34 cm ± 1.10 cm, respectively. A classification system of types A, B and C was developed. The calculated L5/S1 intervertebral space exposure percentages of types A, B and C were 32.21%, 82.58% and 54.68%, respectively. During L5/S1 anterior interbody surgery, type B intervertebral discs can be exposed conveniently, preventing injury of the iliac vessels, which was also observed in 54.68% and 32.21% of the type C and type A discs, respectively. Because the type A intervertebral disc has minimal exposure, the risk of iliac vascular injury is relatively high in these patients.

    Full Text Available Background Anterior cruciate ligament (ACL is a Strengthener ligament of the knee. About 50 persons per 100,000 annually counter ACL rupture. Based on studies, the majority of people who have high mobility jobs, and had reconstruction surgery after ACL rupture, have returned to pre-injury level of activity. Aims We compared two methods of surgery (aperfix and endobutton in this article. We want to answer these two main questions in this study:1 is the effectiveness of surgical methods (aperfix and endobutton in patients with anterior cruciate ligament rupture, the same?.2 Are the aspects of the knee function, in two surgical methods (aperfix and endobutton after ACL reconstruction surgery, the same? Methods This study is a prospective clinical trial on patients who had complete ACL rupture in an isolated trauma, who were nominated for ACL reconstruction surgery. We excluded the cases that had underlying disease or other damages from the study. 100 patients were randomly divided into two groups of 50 individuals. Then each group underwent surgery. The femoral fixations were by the two common methods of ";;;;;;;;;;;Aperfix";;;;;;;;;;; or ";;;;;;;;;;;Endobutton";;;;;;;;;;;. We followed up, the cases one year after surgery and evaluated them by lysholm score as well as with IKDC score. Results The mean lysholm score and IKDC score do not have statistically significant difference in the two groups. (Mean lysholm score in Aperfix group=95.66 vs. 94.56 in Endobutton group (p=0.057 and IKDC score=92.32 in Aperfix group vs 92.20 in Endobutton group (p=0.28. However, in some aspects of knee function, such as locking, Swelling, and climbing stairs, patients who had undergone Aperfix approach, had better results. Conclusion Surgical methods have little difference however due to better results in some aspects of knee functions in this study and due to other studies, it can be said Aperfix method slightly has more benefits.

    With its inception nearly half a century ago through the pioneering work of Dandy, McLean, and Smith, anterior skull base (ASB) surgery is a relatively young discipline. It became a distinct entity in 1963 when Ketcham popularized the combined transcranial transfacial approach for en bloc resection of tumors of the paranasal sinuses extending into the anterior cranial fossa. However, because these procedures resulted in major morbidities and mortalities, alternative modes of treatment were sought. Since the 1970s, the introduction and promotion of the surgical endoscope by Messerklinger, Stammberger, and Kennedy, commenced the era of endoscopic sinus surgery. Thaler and colleagues described the utility of the endoscope for ASB surgery at the turn of the century. This allowed direct visualization and safer, more accurate removal of tumors. In 2001, Casiano reported the first purely endoscopic endonasal ASB resection, a novel technique that has been adopted by major skull base centers. The success of ASB surgery can be attributed to both the development of the skull base team as well as improvements in surgical techniques, instrumentation, and visualization technology. In this article, we review the historical evolution of ASB surgery as we approach the 50th anniversary since its recognition as a distinct entity.

    To gain a better understanding of the precise anatomy of the lateral ligaments of the ankle through a systematic review of published cadaveric studies in order to improve anatomical minimally invasive surgery (MIS) for treatment of chronic ankle instability (CAI). A systematic review of the literature was performed using the PubMed, EMBASE, Cochrane databases and Web of Science on June 2015 with the two search concepts: "lateral ligament of the ankle" and "anatomy". Anatomical studies that reported gross anatomy of the anterior talar fibular ligament (ATFL) and calcaneal fibular ligament (CFL) in English were included to assess the morphology and origins and insertions of the ligaments. All records found in the literature search were screened by title and abstract. Potentially relevant articles were selected for full-text review. Each of the identified articles was reviewed and included in qualitative synthesis. The following data were abstracted from the included articles: authors, date of publication, sample size, mean age, the length and the width of the each ligament, number of bundle of the ATFL and the location and the footprint of the origins and insertions for the ATFL and CFL. Sixteen studies were identified indicating the length of the ATFL and CFL was 12-24.8 and 18.5-35.8 mm, respectively, while the width was 5-11.1 and 4.6-7.6 mm, respectively. Fibular origins of the ATFL and CFL were located on the anterior border of distal fibula at a distance of 10-13.8 and 5.3-8.5 mm proximal to the tip of the fibula, respectively. The talar insertion of the ATFL was located 14.2-18.1 mm to the subtalar joint or 11.3-14.8 mm to the anterolateral corner of the talar body. The calcaneal insertion of the CFL was located 12.1-13 mm to the subtalar joint or 13.2-27.1 mm to the peroneal tubercle on the lateral wall of calcaneus. Systematic review of the literature of the research for the ATFL and CFL has identified the morphology of the ligaments and their

    Background Knees undergoing revision anterior cruciate ligament (ACL) reconstruction typically have more intra-articular injuries than do knees undergoing primary reconstruction. Hypothesis Previous partial meniscectomy (PM) is associated with a higher rate of chondral lesions at revision ACL reconstruction, whereas previous meniscal repair (MR) is not associated with a higher rate of chondral lesions at revision ACL reconstruction, compared with knees undergoing revision ACL with no previous meniscal surgery. Study design Cohort study (Prevalence); Level of evidence, 2. Methods Data from a multicenter cohort was reviewed to determine the history of prior meniscal surgery (PM/MR) and the presence of grade II/III/IV chondral lesions at revision ACL reconstruction. The association between previous meniscal surgery and the incidence of chondral lesions was examined. Patient age was included as a covariate to determine if surgery type contributes predictive information independent of patient age. Results The cohort included 725 ACL revision surgeries. Chondrosis was associated with patient age (P meniscal surgery (P meniscal surgery (P meniscal surgery and knees with previous MR (P = .7). Previous partial meniscectomy was associated with a higher rate of chondrosis in the same compartment compared with knees without previous meniscal surgery (P meniscal surgery independent of the effect of patient age. Previous partial meniscectomy is associated with a higher incidence of articular cartilage lesions, whereas previous meniscal repair is not. Although this association may reflect underlying differences in the knee at the time of prior surgery, it does suggest that meniscal repair is preferable when possible at the time of ACL reconstruction.

    There is limited information on clinical outcomes after anterior lumbar interbody fusion (ALIF) based on the indications for surgery. To compare the clinical and radiological outcomes of ALIF for each surgical indication. This prospective clinical study included 125 patients who underwent ALIF over a 2-year period. The patients were evaluated preoperatively and postoperatively. Outcome measures included the Short Form-12, Oswestry Disability Index, Visual Analog Scale, and Patient Satisfaction Index. After a mean follow-up of 20 months, the clinical condition of the patients was significantly better than their preoperative status across all indications. A total of 108 patients had a Patient Satisfaction Index score of 1 or 2, indicating a successful clinical outcome in 86%. Patients with degenerative disk disease (with and without radiculopathy), spondylolisthesis, and scoliosis had the best clinical response to ALIF, with statistically significant improvement in the Short Form-12, Oswestry Disability Index, and Visual Analog Scale. Failed posterior fusion and adjacent segment disease showed statistically significant improvement in all of these clinical outcome scores, although the mean changes in the Short Form-12 Mental Component Summary, Oswestry Disability Index, and Visual Analog Scale (back pain) were lower. The overall radiological fusion rate was 94.4%. Superior radiological outcomes (fusion >90%) were observed in patients with degenerative disk disease (with and without radiculopathy), spondylolisthesis, and failed posterior fusion, whereas in adjacent segment disease, it was 80%. ALIF is an effective treatment for degenerative disk disease (with and without radiculopathy) and spondylolisthesis. Although results were promising for scoliosis, failed posterior fusion, and adjacent segment disease, further studies are necessary to establish the effectiveness of ALIF in these conditions.

    The purpose of this study is to compare the efficacy and safety of anterior cervical discectomy and fusion (ACDF) and cervical total disc replacement (CTDR) as revision surgeries for symptomatic adjacent segment degeneration (ASD) in cases with previous ACDF. Between 2010 and 2014, 41 patients with previous cervical fusion surgery underwent ACDF or CTDR for symptomatic ASD. Twenty-two patients in the ACDF group underwent 26 ACDFs, and 19 patients in the CTDR group underwent 25 arthroplasties for symptomatic ASD. Clinical outcomes were assessed by a visual analogue scale (VAS) for arm pain, the neck disability index (NDI) and Odom's criteria. Radiological evaluations were performed preoperatively and postoperatively to measure changes in the range of motion (ROM) of the cervical spine and adjacent segments and arthroplasty level. The radiological change of ASD was assessed in radiographs. Clinical outcomes as assessed with VAS for arm pain and Odom's criteria were significantly improved in both groups. The CTDR group showed better NDI improvement after surgery (Padjacent segment between the ACDF and CTDR groups (Padjacent segment compared with the CTDR group (Padjacent segment, and a lower incidence of adjacent segment degeneration than did the ACDF group.

    Postoperative malalignment of the cervical spine may alter cervical spine mechanics and put patients at risk for clinical adjacent segment pathology requiring surgery. To investigate whether a relationship exists between cervical spine sagittal alignment and clinical adjacent segment pathology requiring surgery (CASP-S) following anterior cervical fusion (ACF). Retrospective matched study. A total of 122 patients undergoing ACF between 1996 and 2008 were identified, with a minimum of 2 years of follow-up. Radiographs were reviewed to measure the sagittal alignment using C2 and C7 sagittal plumb lines, distance from the fusion mass plumb line to the C2 and C7 plumb lines, the alignment of the fusion mass, caudally adjacent disc angle, the sagittal slope angle of the superior end plate of the vertebra caudally adjacent to the fusion mass, T1 sagittal angle, overall cervical sagittal alignment, and curve patterns by Katsuura classification. A total of 122 patients undergoing ACF between 1996 and 2008 were identified, with a minimum of 1 year of follow-up. Patients were divided into groups according to the development of CASP (control/CASP-S) and by number/location of levels fused. Radiographs were reviewed to measure the sagittal alignment using C2 and C7 sagittal plumb lines, distance from the fusion mass plumb line to the C2 and C7 plumb lines, the alignment of the fusion mass, caudally adjacent disc angle, the sagittal slope angle of the superior end plate of the vertebra caudally adjacent to the fusion mass, T1 sagittal angle, overall cervical sagittal alignment, and curve patterns by Katsuura classification. Appropriate statistical tests were performed to calculate relationships between the variables and the development of CASP-S. No funds were received in support of this work. No benefits in any form have been or will be received from a commercial party related directly or indirectly to the subject of this article. The groups were similar with regard to

    Progress in microneurosurgical techniques, neuroanesthesiology, and intraoperative imaging enables surgery using small incisions and craniotomy, in accordance with the keyhole surgery concept. Supraorbital craniotomy is the most widespread minimally invasive approach. There are a number of supraorbital craniotomy modifications, regarding different soft tissue incisions and the extent of craniotomy. We present the first results of using mini-orbitozygomatic craniotomy for aneurysms of the anterior circle of Willis and space-occupying lesions of the anterior and middle cranial fossae performed through an eyebrow incision. Forty five patients were operated on using mini-orbitozygomatic (MOZ) craniotomy in the period between March 2014 and December 2015. Fifteen supratentorial aneurysms were clipped, and 30 space-occupying lesions were resected. Most patients had unruptured aneurysms (10 patients). Five patients had a history of SAH. The aneurysm localization was as follows: 8 anterior communicating artery aneurysms, 4 aneurysms of the internal carotid artery in the area of the posterior communicating artery orifice, and 3 ophthalmic aneurysms. The Hunt-Hess scale was used to evaluate the patients' condition, and the Fisher scale was used to quantify SAH volume. Surgery was performed 14 days after SAH, on average. Contrast-enhanced MRI of the brain was the diagnostic method of choice in a group of patients with space-occupying lesions within the anterior and middle cranial fossae. In some cases, patients underwent CT with reconstruction for assessment of the skull base bone structures. The mean age of patients was 58.3 years. All aneurysms were completely excluded from the cerebral blood flow. No serious complications and deaths in a group of aneurysm patients occurred. Complete tumor removal was performed in 28 patients. Two patients having pituitary macroadenomas with supra- and parasellar spread underwent subtotal resection due to adenoma invasion into the cavernous

    To determine the suitability of amniotic membrane an bovine bone xenografts for the use in spinal surgery and anterior cranial for a generations. Fifteen patients with anterior cranial fossa defects and spinal bone fractures received bovine bone xenografts and 10 patients with meningomyeloceles received amniotic membranes (produced by the Malaysian National Tissue Bank) were analysed retrospectively. Clinical criterias like fever, signs of inflammation, breakdown of graft implant, non specific reaction to the nervous tissue were analysed haematological and radiologically. All patients who received the bovine grafts and amniotic membranes did not show any evidence of inflammation or fever. There were no graft implant breakdowns. There was no radiological or clinical evidence of specific or non specific reaction to the nervous tissue after 12-36 months followup Amniotic membranes and bovine xenografts may be used in the healing and reconstruction of spinal and cranial defects. Despite no evidence of rejection and infection after 36 months, a long term followup is still needed

    Football puts athletes at risk for knee injuries such meniscus and anterior cruciate ligament (ACL) tears, which are associated with the development of osteoarthritis (OA). Previous knee surgery, player position, and body mass index (BMI) may be associated with knee OA. In elite football players undergoing knee magnetic resonance imaging at the National Football League's Invitational Combine, the prevalence of knee OA is associated with previous knee surgery and BMI. Retrospective cohort. Level 4. A retrospective review was performed of all participants of the National Football League Combine from 2005 to 2009 who underwent magnetic resonance imaging of the knee because of prior knee injury, surgery, or knee-related symptoms or concerning examination findings. Imaging studies were reviewed for evidence of OA. History of previous knee surgery-including ACL reconstruction, meniscal procedures, and articular cartilage surgery-and position were recorded for each athlete. BMI was calculated based on height and weight. There was a higher prevalence of OA in knees with a history of previous knee surgery (23% vs 4.0%, P 30 kg/m 2 was also associated with a higher risk of OA ( P = 0.007) but player position was not associated with knee OA. Previous knee surgery, particularly ACL reconstruction and partial meniscectomy, and elevated BMI are associated with knee OA in elite football players. Future research should investigate ways to minimize the risk of OA after knee surgery in these athletes. Treatment of knee injuries in football athletes should consider chondroprotection, including meniscal preservation and cartilage repair, when possible.

    Indocyanine green videoangiography (ICG-VA) is an important intraoperative adjunct for saccular aneurysm surgery, but its efficacy in surgery for dissecting aneurysms has rarely been reported. The authors describe the usefulness of preclipping ICG-VA in a rare case of a ruptured dissecting aneurysm located at the precommunicating (A1) segment of the anterior cerebral artery. A 52-year-old woman, with no history of connective tissue diseases or vascular disorders, presented with sudden headache and convulsion. The CT scan showed that the patient had subarachnoid hemorrhage. Angiography showed a dissecting aneurysm in the left A1 segment of the anterior cerebral artery. Thus, the patient underwent trapping of the dissecting aneurysm. ICG-VA was used as an intraoperative adjunct before and after clipping. The preclipping ICG-VA showed the heterogeneously bright dissecting aneurysm and branching arteries even in the presence of hematoma. Preclipping ICG-VA may enhance the advantage of direct surgery for dissecting aneurysm by allowing visualization of the extent of the dissected vascular wall and the related branching arteries. ICG-VA can be an indispensable adjunct to minimize the compromise from the surgical treatment for intracranial dissecting aneurysms. Copyright © 2017 by the Congress of Neurological Surgeons

    A 49-year-old woman with painless reduction in visual acuity in her left eye was found to have nonarteritic anterior ischemic optic neuropathy (NAION). Fluorescein angiography revealed optic disc capillary leakage consistent with "luxury perfusion." Contrast-enhanced FLAIR magnetic resonance imaging (MRI) showed marked enhancement of the left optic disc. Resolution of the optic disc edema and the MRI abnormalities followed a similar time course. This report appears unique in documenting the MRI findings of luxury perfusion in NAION.

    To translate into Spanish and validate the Urethral Stricture Surgery Patient-Reported Outcome Measure (USS-PROM) questionnaire, assessing its psychometric properties and determining its suitability for clinical use in our community. We also assessed the potential changes in ejaculatory function using the Male Sexual Health Questionnaire-Ejaculatory Dysfunction (MSHQ-EjD). A systematic translation of the British version was performed. Patients scheduled for anterior urethral stricture surgery between September 2014 and September 2015 were prospectively included in the study. All patients completed the questionnaire before and after the surgery. We conducted an in-depth psychometric study of the questionnaire. We assessed the responses of a total of 40 patients. The questionnaire showed its validity, presenting an excellent negative correlation between the voiding symptom scores and the maximum flow (r=-0.6, P<.001), and also showed significant improvement in the EQ5D-VAS (visual analogue scale) and the time trade-off. For internal consistency, the Cronbach's alpha was 0.701. For the test-retest reliability, the overall intraclass correlation coefficient (ICC) was 0.974, and the ICC for each item separately ranged from 0.799 to 0.980. We observed significant improvement in all items regarding urinary symptoms and health-related quality of life (P<.001), thereby demonstrating the response capacity to changing the questionnaire. There were no significant changes in the MSHQ-EjD. The Spanish version of the USS-PROM questionnaire is a valid instrument for quantifying changes in voiding symptoms and the health-related quality of life of patients undergoing anterior urethral surgery.

    To report the outcomes of the use of intracameral bevacizumab for iris neovascularization occurring after silicone oil (SO) removal in eyes undergoing vitreoretinal surgery (VRS). This study included 12 eyes that had iris neovascularization after SO removal. The clinical outcomes of 12 eyes after intravitreal bevacizumab injection were reviewed. There were eight men and four women with an average age of 41.58+/-12.68 years. All eyes had VRS for various vitreoretinal diseases. After the mean follow-up period of 9.7+/-5.3 months, SO removal was performed. Then, the patients were followed for more than 2 months and detailed retinal examinations and intraocular pressure (IOP) were normal during this period, but rubeosis iridis (RI) developed. RI was treated with 1 dose of 1.25 mg bevacizumab into the anterior chamber. After a mean follow-up period of 4.8+/-2.2 months, the regression of iris neovacularization was detected and IOP was below 21 mmHg in all eyes. Anterior segment neovascularization (ASNV) may develop through various mechanisms in patients with VRS after SO removal, and anterior chamber injection of bevacizumab may lead to regression of ASNV.

    To understand the location characteristics of the lumbosacral autonomic nerve plexus and the morphological changes so as to provide the anatomic theoretical basis for the protection of autonomic nerve during the lower lumbar anterior approach operation. A random anatomic investigation was carried out on 19 formalin-treated adult cadavers (15 males and 4 females; aged 44-78 years, mean 64 years). The anterior median line (connection of suprasternal fossa point and the midpoint of the symphysis pubis) was determined, and the characteristics of abdominal aortic plexus (AAP), inferior mesenteric plexus (IMP), and superior hypogastric plexus (SHP) were observed. The relationship between the autonomic nerve and the anterior median line was measured and recorded. APP and IMP were found to be located chiefly in front of the abdominal aorta in a reticular pattern, and the nerve fibers of the two nerve plexuses were more densely at the left side of abdominal aorta than at the right side. Superior hypogastric plexus showed more distinct main vessel variations, including 4 types. The main vessel length of the SHP was (59.38 ± 12.86) mm, and the width was (11.25 ± 2.92) mm. The main vessels of SHP were mainly located at the left side of the ventral median line (10, 52.6%) and anterior lumbar vertebra (13, 68.4%). The main vessels extended down to form the left and right hypogastric nerves. It is applicable to expose the nerve from the right side of centrum and move the autonomic nerve and blood vessel as a whole during anterior lower lumbar operation. In this way, the dissection to separate nerve plexus is not needed, thus nerve injury can be avoided to the largest extent.

    Full Text Available Spinal metastasis of differentiated thyroid cancer can have a favorable prognosis if radical surgery is performed. We encountered a case of spinal metastasis involving three anterior vertebral bodies at the posterior element fusion level and successfully achieved adequate stability by radical surgery involving only the anterior elements. A 67-year-old woman who had numbness and muscle weakness in the lower limbs caused by metastatic spinal tumor at the posterior element fusion level of L1–L3 vertebrae was treated with radical surgery of only the anterior element to gain stability. Similar situations may occur in cases involving other malignant tumor metastases or spinal primary tumors. If such a case occurs, this method could be useful in preventing metastasis to the posterior element.

    The authors put-forth this technical report to establish the feasibility of performing an anterior cervical corpectomy and fusion (ACCF) and a two-level anterior cervical discectomy and fusion (ACDF) using a minimally invasive approach with tubular retractors. First case: cervical spondylotic myelopathy secondary to a large postero-inferiorly migrated disc treated with corpectomy and reconstruction with a mesh cage and locking plate. Second case: cervical disc herniation with radiculopathy treated with a two-level ACDF. Both cases were operated with minimally invasive approach with tubular retractor using a single incision. Technical aspects and clinical outcomes have been reported. No intra or post-operative complications were encountered. Intra-operative blood loss was negligible. The patients had a cosmetic scar on healing. Standard procedure of placement of tubular retractors is sufficient for adequate surgical exposure with minimal invasiveness. Minimally invasive approach to anterior cervical spine with tubular retractors is feasible. This is the first report on use of minimally invasive approach for ACCF and two-level ACDF.

    To evaluate the clinical results of using end plate rings in preventing subsidence of titanium cage in anterior cervical corpectomy and fusion (ACCF) surgery. The clinical data of 71 patients with cervical spondylotic myelopathy underwent ACCF in single segment from February 2008 to February 2011 were retrospectively analyzed. There were 38 males and 33 females, aged from 39 to 74 years old with a mean of 53.8 years. Thirty-three were used end plate rings and thirty-eight were not used (end plate rings group and no end plate ring group, respectively). The Japanese Orthopaedic Association (JOA) score, Odom's scale, imaging data were used to evaluate the clinical effects. Imaging data including Cobb angle of fusion segment, intervertebral height of anterior border (Da) and posterior border (Dp), the mean intervertebral height (Dm). All patients were followed up from 13 to 34 months with an average of 19.5 months. Between two groups, there was no significant difference in Cobb angle of fusion segment and the mean intervertebral height (Dm) before surgery and one week after surgery. Whereas, one year after surgery, the Cobb angle of end plate ring group was (9.4 ± 3.8) degrees, and contral group was (7.5 ± 3.9) degrees, which was significantly lower than that of end plate ring group. Meanwhile, the Dm of end plate ring group was (57.3 ± 2.2) mm, and no end ring group was (55.2 ± 2.6) mm which was significantly lower than that of end plate ring group. The subsidence in end plate ring group was 57.6%, and was 78.9% in no end plate ring group. There was no significant difference in JOA score before and after surgery between two groups. At 1 year after operation, 90.9% (30/33) got excellent or good results in end plate ring group, 89.5% (33/38) got excellent or good results in contral group. The use of end plate rings could not completely prevent the subsidence of titanium cage, however, which can decrease the occurrence rate of the subsidence and lessen its degree.

    In view of conflicting neuroimaging results regarding autonomic-specific activity within the anterior cingulate cortex (ACC), we investigated autonomic responses to direct brain stimulation during stereotactic limbic surgery. Skin conductance activity and accelerative heart rate responses to multi-voltage stimulation of the ACC (n = 7) and paralimbic subcaudate (n = 5) regions were recorded during bilateral anterior cingulotomy and bilateral subcaudate tractotomy (in patients that had previously received an adequate lesion in the ACC), respectively. Stimulations in both groups were accompanied by increased autonomic arousal. Skin conductance activity was significantly increased during ACC stimulations compared with paralimbic targets at 2 V (2.34 +/- .68 [score in microSiemens +/- SE] vs. .34 +/- .09, p = .013) and 3 V (3.52 +/- .86 vs. 1.12 +/- .37, p = .036), exhibiting a strong "voltage-response" relationship between stimulus magnitude and response amplitude (difference from 1 to 3 V = 1.15 +/- .90 vs. 3.52 +/- .86, p = .041). Heart rate response was less indicative of between-group differences. This is the first study of its kind aiming at seeking novel insights into the mechanisms responsible for central autonomic modulation. It supports a concept that interregional interactions account for the coordination of autonomic arousal.

    AIM: To evaluate the functional outcomes of the Bristow-Latarjet procedure in patients with recurrent anterior glenohumeral instability. PATIENTS AND METHODS: Personal clinical records of 42 patients with 45 operated shoulders were reviewed retrospectively. Patient age at time of first dislocation, injury mechanism, and number of recurring dislocations before surgery were recorded. The overall function and stability of the shoulder was evaluated. RESULTS: Thirty five (78%) of the scapulohumeral humeral instabilities were caused by trauma. The mean number of recurring dislocations was 9 (95% confidence interval [CI], 0–18); one patient had had 17 recurrences. Mean follow-up 46 months (95% CI, 16-88). No dislocation happened postoperatively. Four patients have fibrous union (9%). Only two had clinical sign of pain and discomfort. One of them was reoperated for screw removal with very good post-operative result. The overall functional outcome was good, with a mean Rowe score of 88 points (95% CI, 78–100). Scores of 27 (64%) of the patients were excellent, 9 (22%) were good, 4 (9.5%) were fair, and 2 (4.5%) were poor. CONCLUSION: The Bristow-Latarjet procedure is a very good surgical treatment for recurrent anterior-inferior instability of the glenohumeral joint. It must not be used for multidirectional instability or psychogenic habitual dislocations. PMID:27275242

A reduced visual analog scale on back pain (from 8.2 to 2.2 and Oswestry disability index (from 67.1% to 25.6% were found at the 2-year follow-up. All patients had achieved resolution of spinal infection with reduced average erythrocyte sedimentation rate (from 83.9 to 14.1 mm/hr and average C-reactive protein (from 54.4 to 4.8 mg/dL. Average kyphotic angle correction was 10.5° (range, 8.4°–12.6° postoperatively and 8.5° (range, 6.9°–10.1° after 2 years. In conclusion, the current iCT-guided navigation approach has been demonstrated to be an alternative method during simultaneous minimally invasive anterior and posterior surgery for infectious spondylitis. It can provide a good intraoperative orientation and visualization of anatomic structures and also a high pedicle screw placement accuracy in patient’s lateral decubitus position.

    The objectives were to evaluate a technique, outcome and complications following anterior greater trochanteric with gluteus medius muscle pedicle bone graft (AMG) procedure in the treatment of adolescent and active adult hip disorders. 20 patients (20 hips) with a mean age of 22.7 ± 15.6 (range 10.0-63.5) years who had undergone AMG and been followed up more than 12 months postoperative were retrospectively enrolled in our study. The AMG procedure was performed in conjunction with subcapital osteotomy for slipped capital femoral epiphysis in 12 and open reduction for fracture/dislocation in 8 hips. At the most recent evaluation, patient functional status was rated by the Harris Hip Score (HHS) and radiographic changes were graded according to Tönnis criteria. Complications were defined as Tönnis grade >2 or hip requiring further surgery. Univariate analysis was used to explore factors associated with complications. Spearman's rank correlation coefficient was calculated between HHS and Tönnis grading. At mean follow-up of 4.4 ± 2.6 (range 1.1-9.5) years, mean HHS was 87.4. Tönnis grading was rated as 0 in 10 hips, 1 in 5 hips, 2 in 2 hips, and 3 in 3 hips. Avascular necrosis of the femoral head as a complication developed in 3 hips (15%). Clinical parameters including age at surgery, duration of follow-up and diagnosis were not significantly associated with postoperative complications. A negative correlation between HHS and Tönnis grade was shown by Spearman's rank correlation (rs = -0.49, p = 0.03). The AMG can be safely recommended as an adjunct bone graft procedure when performing anterior open reduction of adolescent and active adult hip disorders.

    A 62-year-old blind man with severe ossification of posterior longitudinal ligament was presented. The patient received posterior laminectomy and fixation. After surgery, the patient was not satisfied with the recovery of upper limbs although the JOA score increased from 9 to 12 points. Because the tactile sensation of his hands is especially important to his daily life, the patient asked for further treatment after 6 months. The paper is to report the novel revision surgery we invented and the outcome of the patient after the novel surgery. We performed the revision surgery using anteriorly approach from C3-7 with a novel technique, which named anterior controllable antedisplacement and fusion (ACAF). The patient was followed up for 6 months. The clinical data including JOA score and radiological images were collected and analyzed. After the revision surgery, the patient had improvement release of numbness of both hands and the JOA score was increased to 14 points. Satisfactory decompression was assessed by MRI post-operation. Bone fusion was confirmed by CT 3 months post-operation. No specific complications related to this surgery was observed. The application of such operative procedure in revision surgery for OPLL has not been reported and might be an alternative choice for patients with unsatisfied outcome from previous posterior surgery.

    Adjacent segment disease (ASD) is one of the problematic complications following anterior cervical decompression and fusion (ACDF). The impact of additional surgery with instruments is still unknown. The objective of this study was to investigate the surgical outcomes of additional ACDF with instruments for symptomatic ASD after an initial ACDF using autogenous iliac grafts without instruments. A total of 56 patients who underwent an additional ACDF with instruments for symptomatic new radicular or myelopathic symptoms from ASD between 2006 and 2012. In this study, subjects were 30 men and 26 women with a mean age of 59.2 ± 9.7 years (range, 50-70 years) at revision surgery. Clinical evaluations were performed preoperatively and repeated at 3 years after operation. There were no cases of intraoperative complications, major neurological or vascular, pseudoarthrosis or wound complications. All of them reported significant improvements in JOA, NDI and VAS on arm pain and neck pain from the preoperative means (P< 0.05). According to our study, additional ACDF with instruments had achieved favorable clinical results on patients who underwent initial ACDF using autogenous iliac grafts without instruments for symptomatic new radiculopathy or myelopathy.

    Secondary orbital implantation surgery can be complex due to scarring of the orbital tissues and can be complicated by implant exposure and extrusion. To evaluate the incidence and risk factors of implant exposure and extrusion following secondary alloplastic orbital implantation surgery in anophthalmic patients. Retrospective analysis of a consecutive series of patients who underwent secondary placement of an alloplastic orbital implant by one surgeon between 2001 and 2016 in the Rotterdam Eye Hospital. implant exposure or extrusion. Other complications. Sixty-three patients underwent secondary orbital placement of scleral-wrapped acrylic (60) or silicone (three) spherical implants. A subset of 25 patients had undergone earlier secondary orbital implant placement (by other surgeons) with exposure/extrusion necessitating additional implant surgery. Two patients were excluded due to lack of follow-up (Implant exposure or extrusion occurred in six of 18 (33%) patients in whom no muscle had been reattached during secondary orbital implantation and in five of 43 (12%) patients in whom the extraocular recti muscles had been attached, but the follow-up time was shorter for the latter group. Surgical treatment for implant exposure/extrusion was required in eleven of 61 patients (18%). Other complications included postoperative volume deficiency despite optimal prosthesis (five of 61, 8%), inclusion cysts (four of 61, 7%) and conjunctivitis sicca (two of 61, 3%). Seven of 61 (11%) patients required fornix deepening and seven (11%) blepharoptosis correction. Secondary orbital implantation of sclera-wrapped alloplastic implants was complicated by implant extrusion or exposure in 12% of cases in which the extraocular muscles were attached to the implant. © 2017 Acta Ophthalmologica Scandinavica Foundation.

    To evaluate the clinical and radiological outcomes of artificial cervical disc replacement (Prodisc-C), dynamic cervical implant and anterior cervical discectomy and fusion (ACDF) in the treatment of cervical spondylosis. From May 2011 to May 2013, a total of 44 cervical spondylosis patients that received cervical disc arthroplasty (Prodisc-C), dynamic cervical implant (DCI) or ACDF were retrospectively reviewed in Orthopedics Department, Beijing Chaoyang Hospital, Capital Medical University.The patients were divided into three groups by surgical methods.Parameters as gender, age, the operation time, blood loss and average hospital stay of three groups were compared.The patients were followed 3 months, 6 months, 12 months and 24 months postoperatively.Neck disability index (NDI), Japanese Orthopaedic Association (JOA) Score and Visual Analogue Scale (VAS) were used to evaluate the clinical outcomes of the three groups.We also measured the cervical lordosis, range of motion of surgical segment and adjacent segment and height of disc at pre-op and post-op. All the patients were got at least 24 months follow-up.The differences between postoperative JOA, NDI and VAS scores and preoperative scores were of statistical significance (P0.05) among three groups.But the operative time and intraoperative blood loss were statistically different (P0.05). There was no statistically significant difference between pre-and postoperative ROM of upper and lower levels among three groups (P>0.05), but had statistically difference in operative levels [(7.0±1.0) mm, (9.2±1.5) mm, (6.8±1.4) mm, Pfusion surgery and ACDF have received good clinical effects in the treatment of spondylotic myelopathy or radicular spondylosis.The artificial cervical disc replacement and dynamic cervical implant can not only recover cervical lordosis and keep the range of motion and stability of the surgical segment, but also reduce the incidence of compensatory motion at adjacent segments and will prevent

    We present a case report on a 53-year-old transsexual woman who developed acute painless vision loss in both eyes during cross-sex hormone treatment. After 10 months of cross-sex hormone treatment, she experienced total vision loss of the right eye and, 6 months later, vision loss to 20/63 in the left eye. After a full ophthalmic exam, bilateral sequential non-arteritic ischemic optic neuropathy (NA-ION) was diagnosed. Extensive etiological work-up revealed no cardiac abnormalities or inherited blood-clotting disorders. A manifest self-administered overdose of transdermal estrogen treatment with serum estradiol levels of 5,765 pg/ml was possibly related to the sequential bilateral NA-ION resulting in nearly total vision loss in this transsexual woman.

    The aim of the study was to find predictive parameters for a successful resumption of pre-injury level of sport 6 months post anterior cruciate ligament (ACL) reconstruction. In a prospective study, 40 patients with a ruptured ACL were surgically treated with semitendinosus tendon autograft. Six months after surgery, strength of knee extensors and flexors, four single-leg hop tests, Anterior Cruciate Ligament-Return to Sport after Injury Scale (ACL-RSI), subjective International Knee Documentation Committee (IKDC) 2000 and the Tampa Scale of Kinesiophobia-11 (TSK-11) were assessed. Seven months post-operatively, a standardized interview was conducted to identify "return to sport" (RS) and "non-return to sport" (nRS) patients. Logistic regression and "Receiver Operating Characteristic" (ROC) analyses were used to determine predictive parameters. No significant differences could be detected between RS and nRS patients concerning socio-demographic data, muscle tests, square hop and TSK-11. In nRS patients, the Limb Symmetry Index (LSI) of single hop for distance (p = 0.005), crossover hop (p = 0.008) and triple hop (p = 0.001) were significantly lower, in addition to the ACL-RSI (p = 0.013) and IKDC 2000 (p = 0.037). The cut-off points for LSI single hop for distance were 75.4 % (sensitivity 0.74; specificity 0.88), and for ACL-RSI 51.3 points (sensitivity 0.97; specificity 0.63). Logistic regression distinguished between RS and nRS subjects (sensitivity 0.97; specificity 0.63). The single hop for distance and ACL-RSI were found to be the strongest predictive parameters, assessing both the objective functional and the subjective psychological aspects of returning to sport. Both tests may help to identify patients at risk of not returning to pre-injury sport. II.

    To evaluate the integrity of the subscapularis tendon by strength, function and magnetic resonance imaging after deltopectoralis access for anterior shoulder instability. 20 patients with anterior shoulder instability have been evaluated. Minimum follow-up was 12 months, with a mean of 40 months. Only male patients were included, with a mean of age of 29 years (20 - 42 years). The patients have been submitted to physical examinations of mobility, muscular strength, Belly Test and Gerber Test. The isokinetic strength in internal and external rotation, in angular speeds of 60(0)/s and 180(0)/s, for both shoulders was measured using a dynamometer. In 15 patients magnetic resonance imaging (MRI) was carried out on both shoulders for evaluating the thickness, cross-sectional area and atrophy of the subscapularis muscle. A significant difference was found between torque peaks at the speed of 60(0)/s for internal (p=0.036) and external (p=0.008) rotation. However, at 180(0)/s the opposite happens (internal rotation: p=0.133; external rotation: p=0.393). Subscapularis muscle thickness and area are significantly smaller than the normal side, with a deficit of 19% and 23%, respectively. According to Rowe and UCLA scores, we find excellent and good results for the majority of patients, with a mean of 88 and 31.6 points, respectively. Despite of the good functional results, open surgery can limit strength and reduce the thickness and the cross-sectional area of subscapularis muscle. However, the best results were found in the patients who had the dominant side operated.

    Dysphonia and dysphagia are common complications of anterior cervical discectomy (ACD). We sought to determine the relationship between dysphagia and in-hospital mortality, complications, speech therapy/dysphagia training, length of hospitalization, and costs associated with ACD. Discharge data from the Nationwide Inpatient Sample for 1,649,871 patients who underwent ACD of fewer than four vertebrae for benign acquired disease between 2001 and 2010 were analyzed using cross-tabulations and multivariate regression modeling. Dysphagia was reported in 32,922 cases (2.0 %). Speech therapy/dysphagia training was reported in less than 0.1 % of all cases and in only 0.2 % of patients with dysphagia. Dysphagia was significantly associated with age ≥65 years (OR = 1.5 [95 % CI 1.4-1.7], P Dysphagia was a significant predictor of aspiration pneumonia (OR = 8.6 [6.7-10.9], P dysphagia training (OR = 32.0 [15.4-66.4], P Dysphagia, vocal cord paralysis, and aspiration pneumonia were significant predictors of increased length of hospitalization and hospital-related costs, with aspiration pneumonia having the single largest impact on length of hospitalization and costs. Dysphagia is significantly associated with increased morbidity, length of hospitalization, and hospital-related costs in ACD patients. Despite the known risk of dysphagia in ACD patients and an established role for the speech-language pathologist in dysphagia management, speech-language pathology intervention appears underutilized in this population.

    Full Text Available A 34-year-old woman presented with pain during menstruation and was diagnosed with endometriosis of the lower rectum. Despite treatment with an LH-RH agonist, she was unable to become pregnant and surgical removal of her endometriosis was recommended. Preoperative magnetic resonance imaging revealed endometriosis localized between the neck of the uterus and rectum with indentation and scuffing. Laparoscopically assisted low anterior resection was performed. Exfoliation was started from the right side of the rectum to the presacral and retrorectal space, and the rectococcygeus ligament was transected. Exfoliation of the retrorectal space was continued to the levator ani muscle and mobilization of the right side of the rectum was performed. In front of the rectum, exfoliation was started posterior to the wall of the vagina, but layers became unclear near the tumor as the tissue was solid in this region. The left hypogastric nerve close to the tumor was inflamed and it was cut. The layer of the exfoliation was connected to the right side of the rectum, the tumor was isolated from the vagina, and the lower rectum was transected at a point 1 cm distal to the tumor with a 60-mm linear stapler. Reconstruction with a 31-mm circular stapler was performed using the double stapling technique. Operative time was 520 min with a blood loss of 320 ml. On the 9th post operative day, a rectovaginal fistula occurred, and ileostomy was performed. The patient was discharged from the hospital on the 25th postoperative day, and 4 months later, stoma closure was performed.

    Systematic review. The primary aim of this review was to evaluate clinical and radiographic outcomes in studies of anterior cervical discectomy and fusion (ACDF) using allograft versus ACDF with autograft, ACDF with cage devices, and cervical disc arthroplasty for the treatment of symptomatic cervical disc disease. ACDF remains the standard of care for patients with cervical radiculopathy who are unresponsive to conservative medical care. However, no known study has compared patient outcomes after ACDF with allograft, ACDF with autograft, ACDF with cage, and disc arthroplasty. After applying strict inclusion criteria, 21 comparisons from 20 studies formed the basis for this review. Patient outcomes included neck and arm pain, neck disability index (NDI), physical component summary (PCS), and mental component summary (MCS) scores from the SF-36, radiographic fusion rate, and select adverse events (e.g., wound infection, dysphagia, and adjacent segment degeneration). The four treatment groups included ACDF with allograft (allograft, n = 1341), ACDF with autograft (autograft, n = 568), ACDF with cage (cage, n = 87), and cervical disc arthroplasty (arthroplasty, n = 603). Neck pain was reduced similarly by 63% to 69% in all groups. Comparable improvements were realized in arm pain after ACDF with allograft (75%) or arthroplasty (73%) that were greater than other treatment groups (62-68%). There was notable improvement in neck disability (61-65%) with allograft and arthroplasty after treatment. PCS scores improved with allograft (42%) and arthroplasty (44%). MCS scores improved modestly (16-21%) with allograft and arthroplasty. Fusion rates were 91% for allograft and autograft and 97% for cage. Adverse events were uncommon in all groups. ACDF with allograft, ACDF with autograft, ACDF with cage, and cervical disc arthroplasty show similar improvements in pain, function, and quality of life with correspondingly low adverse event rates. All ACDF procedures result in high

  18. Iliac crest autograft versus alternative constructs for anterior cervical spine surgery: Pros, cons, and costs

    2012-01-01

    Background: Grafting choices available for performing anterior cervical diskectomy/fusion (ACDF) procedures have become a major concern for spinal surgeons, and their institutions. The “gold standard”, iliac crest autograft, may still be the best and least expensive grafting option; it deserves to be reassessed along with the pros, cons, and costs for alternative grafts/spacers. Methods: Although single or multilevel ACDF have utilized iliac crest autograft for decades, the implant industry now offers multiple alternative grafting and spacer devices; (allografts, cages, polyether-etherketone (PEEK) amongst others). While most studies have focused on fusion rates and clinical outcomes following ACDF, few have analyzed the “value-added” of these various constructs (e.g. safety/efficacy, risks/complications, costs). Results: The majority of studies document 95%-100% fusion rates when iliac crest autograft is utilized to perform single level ACDF (X-ray or CT confirmed at 6-12 postoperative months). Although many allograft studies similarly quote 90%-100% fusion rates (X-ray alone confirmed at 6-12 postoperative months), a recent “post hoc analysis of data from a prospective multicenter trial” (Riew KD et. al., CSRS Abstract Dec. 2011; unpublished) revealed a much higher delayed fusion rate using allografts at one year 55.7%, 2 years 87%, and four years 92%. Conclusion: Iliac crest autograft utilized for single or multilevel ACDF is associated with the highest fusion, lowest complication rates, and significantly lower costs compared with allograft, cages, PEEK, or other grafts. As spinal surgeons and institutions become more cost conscious, we will have to account for the “value added” of these increasingly expensive graft constructs. PMID:22905321

    A multicenter, retrospective cohort study. To evaluate clinical outcomes in patients with reintubation after anterior cervical spine surgery. A total of 8887 patients undergoing anterior cervical spine surgery were enrolled in the AOSpine North America Rare Complications of Cervical Spine Surgery study. Patients with or without complications after surgery were included. Demographic and surgical information were collected for patients with reintubation. Patients were evaluated using a variety of assessment tools, including the modified Japanese Orthopedic Association scale, Nurick score, Neck Disability Index, and Short Form-36 Health Survey. Nine cases of postoperative reintubation were identified. The total prevalence of this complication was 0.10% and ranged from 0% to 0.59% across participating institutions. The time to development of airway symptoms after surgery was within 24 hours in 6 patients and between 5 and 7 days in 3 patients. Although 8 patients recovered, 1 patient died. At final follow-up, patients with reintubation did not exhibit significant and meaningful improvements in pain, functional status, or quality of life. Although the prevalence of reintubation was very low, this complication was associated with adverse clinical outcomes. Clinicians should identify their high-risk patients and carefully observe them for up to 2 weeks after surgery.

    With the aging of population, the number of Total Hip Replacement Surgeries (THR) increased year by year. In THR, inaccurate position of the implanted prosthesis may lead to the failure of the operation. In order to reduce the failure rate and acquire the real-time pose of Anterior Pelvic Plane (APP), we propose a measurement system in this paper. The measurement system includes two parts: Initial Pose Measurement Instrument (IPMI) and Real-time Pose Measurement Instrument (RPMI). IPMI is used to acquire the initial pose of the APP, and RPMI is used to estimate the real-time pose of the APP. Both are composed of an Inertial Measurement Unit (IMU) and magnetometer sensors. To estimate the attitude of the measurement system, the Extended Kalman Filter (EKF) is adopted in this paper. The real-time pose of the APP could be acquired together with the algorithm designed in the paper. The experiment results show that the Root Mean Square Error (RMSE) is within 1.6 degrees, which meets the requirement of THR operations.

    To explore a new method of whole-process digital esthetic prosthodontic rehabilitation combined with periodontic surgery for complicated anterior teeth esthetic defects accompanied by soft tissue morphology, to provide an alternative choice for solving this problem under the guidance of three-dimensional (3D) printing digital dental model and surgical guide, thus completing periodontic surgery and digital esthetic rehabilitation of anterior teeth. In this study, 12 patients with complicated esthetic problems accompanied by soft tissue morphology in their anterior teeth were included. The dentition and facial images were obtained by intra-oral scanning and three-dimensional (3D) facial scanning and then calibrated. Two esthetic designs and prosthodontic outcome predictions were created by computer aided design /computer aided manufacturing (CAD/CAM) software combined with digital photography, including consideration of white esthetics and comprehensive consideration of pink-white esthetics. The predictive design of prostheses and the facial appearances of the two designs were evaluated by the patients. If the patients chose the design of comprehensive consideration of pink-white esthetics, they would choose whether they would receive periodontic surgery before esthetic rehabilitation. The dentition design cast of those who chose periodontic surgery would be 3D printed for the guide of periodontic surgery accordingly. In light of the two digital designs based on intra-oral scanning, facing scanning and digital photography, the satisfaction rate of the patients was significantly higher for the comprehensive consideration of pink-white esthetic design (P3D printed digital dental model and surgical guide provided significant instructions for periodontic surgery, and achieved success transfer from digital design to clinical application. The prostheses were fabricated by CAD/CAM, thus realizing the whole-process digital esthetic rehabilitation. The new method for esthetic

    A case of left anterior and middle cerebral arterial occlusion with angiographic features similar to Moyamoya disease was reported. IMP SPECT of the patient revealed the success of bypass surgery clearly. The patient complained of transient right hemiparesis with aphasia 4 times. The cerebral arteriography disclosed occlusions of left anterior and middle cerebral arteries at their proximal portions. Right internal carotid and its branches were normal. I-123 IMP SPECT study showed hypoperfusion in left temporal lobe, basal ganglia with incomplete reperfusion on the delayed (4 hours after injection) SPECT images. After the superficial temporal-middle cerebral artery anastomosis, I-123 IMP SPECT showed improvement of the brain blood flow. I-123 IMP SPECT was very useful in detecting the ischemic areas and evaluating the revascularizing surgery in this case. (author)

    Retrospective, single-center analysis of multilevel anterior fusion rates and health-related quality-of-life outcomes of mineralized collagen and bone marrow aspirate (BMA) in anterior interbody fusion cages for spine fusion surgery. To determine the ability and effectiveness of mineralized collagen and BMA to achieve multilevel anterior spinal fusion in adult spinal deformity patients when placed in carbon fiber reinforced polymer cages. High rates of postoperative pain and nonunion can result from spine fusion procedures. Factors that affect the success of fusion include patient comorbidities, position of implant, and mechanical and biological deficiencies, as well as the choice of bone graft replacement. Analysis of radiographic images and health-related quality-of-life outcomes was performed for a consecutive series of 22 prospectively enrolled adult spinal deformity patients with 104 total anterior fusion levels. Fusions were graded by 3 blinded surgeons not involved in the operative procedure; each fusion was graded on a 1-4 scale based on fusion mass appearance. Levels with an average fusion grade of 1-2.4 were classified as fused; levels with an average grade >2.5 were classified as not fused. The mean patient age was 51.5 years (range, 38-61) with 21 females. A total of 95% of anterior operative levels were graded as fused based on flexion/extension and full-length biplane radiographs at 1 year. Computed tomography grading showed a reduced fusion rate at 87% overall. There was a statistically significant improvement in the Oswestry Disability Index and Scoliosis Research Society 22-item questionnaire scores at 1 and 2 years after index surgery. Fusion rates in multilevel anterior spinal fusion using mineralized collagen and BMA are relatively low compared with fusion rates of 95% or more reported in the existing literature on long fusions with bone morphogenetic protein.

    Infection is an uncommon complication of anterior cervical spine surgery. Most deep postoperative infections are thought to be related to occult esophageal perforation. Direct inoculation from the oropharynx has not been previously reported in the literature. The purpose of this study is to report a case of recurrent infection after anterior cervical decompression and fusion suspected to have resulted from direct communication between the oropharynx and deep neck space. This study is a case report. This study included longitudinal clinical and radiological follow-up. A 48-year-old woman who underwent anterior cervical corpectomy and fusion from C3 to C6 and posterior spinal fusion from C3 to C7 presented at 2 weeks and 5 months postoperatively with a deep neck space infection. She underwent surgical debridement each time. Workup of the second infection found a subtle cortical breach in the mandible at the site of prior invasive dental work. This case describes the workup and management of a patient who presented with recurrent deep neck space infection following anterior cervical spine surgery. This is the first report of a postoperative infection related to direct communication between the oropharynx and deep neck space via a cortical breach of the mandible. Copyright © 2016.

    Observational study using a retrospective single-institute database. To investigate the prevalence of a medial loop (ML) of the vertebral artery (VA) and internal carotid artery (ICA), which might be an anatomical risk factor for arterial injury in anterior cervical surgeries. Anterior cervical spine surgeries are generally considered to be safe and effective. VA injury is one of the most serious complications during anterior procedures. Several articles have reported this complication, which might be because of the anomalous course of VA at V2 segment. The prevalence and anatomical features of those high-risk cases were, however, not investigated. Consecutive Japanese subjects, who underwent contrast-enhanced computed tomography (CT) or computed tomographic angiography (CTA) for reasons other than evaluation of cervical artery disease from November 2011 to October 2012 in our institution, were reviewed. Exclusion criteria included poor images, past surgery, and endovascular intervention of cervical spine and its vessels. The definition of ML was set as the course of VA and ICA extended medially inside the uncovertebral joint. We also investigated whether those anomalous courses were detectable by plain CT. A total of 1251 subjects with age ranging from 14 to 93 years with a mean of 56.1 years were surveyed. Among them, 1054 subjects were eligible and the others were excluded. A total of 421 subjects were male, and 633 were female. There were 10 cases (1%) with an ML of the VA, and 2 (0.2%) cases with a medial loop of internal carotid artery. Five of the 10 cases with a medial loop of vertebral artery were aberrant into the vertebral body, which were detectable by plain CT. Importantly, the other five cases could not be seen on the CT. One percent of all subjects showed higher anatomical risk for VA and ICA injury during anterior surgery, half of which were undetectable by plain CT. Preoperative evaluation for vascular anatomy may be necessary for safer surgical

    There is inadequate evidence to determine when to perform surgery on anterior cruciate ligament-deficient knees. To study the association between timing of anterior cruciate ligament reconstruction and the risk of having meniscal tears and cartilage lesions. Cohort study (prognosis); Level of evidence, 2. All patients registered in the Norwegian National Knee Ligament Registry who had undergone primary anterior cruciate ligament reconstruction from 2004 and throughout 2006 were reviewed. Logistic regression analyses were used to estimate the relationship between time from injury until anterior cruciate ligament surgery and the risk of meniscal tears or cartilage lesions. Of a total of 3475 patients, there were 909 patients (26%) with cartilage lesions, 1638 patients (47%) with meniscal tears, and 527 patients (15%) with both cartilage and meniscal lesions. The odds of a cartilage lesion in the adult knee (>16 years) increased by 1.006 (95% confidence interval, 1.003-1.010) for each month that elapsed from injury to surgery. The cartilage in young adults (17-40 years) deteriorated further with an increase in odds of 1.03 (95% confidence interval, 1.02-1.05) related to the aging in years of the patient. The odds for meniscal tears in young adults increased by 1.004 (95% confidence interval, 1.002-1.006) for each month that elapsed since injury. The presence of 1 degenerative lesion increased the odds of having the other degenerative lesion by between 1.6 and 2.0 in all patient groups. The odds of a cartilage lesion in the adult knee increased by nearly 1% for each month that elapsed from the injury date until the surgery date and that of cartilage lesions were nearly twice as frequent if there was a meniscal tear, and vice versa.

    Laryngeal anterior commissure (AC) cancer has been the subject of much controversy. Our study was aimed at pathologically evaluating the tendency of AC cancer to invade the thyroid cartilage and analyzing the role of thyroid cartilage invasion by tumor cells at the AC as an anatomic cause for irradiation failure. Our study included 36 patients with glottic cancer involving AC. Patients with recurrent or persistent disease after radiotherapy underwent salvage surgery. Surgical specimens from 22 patients who had open surgery, either as primary or salvage surgery, were available for pathologic examination to identify the presence of cartilage invasion. We found microscopic invasion of the thyroid cartilage in 40.9% of the studied tumors. Only 21.4% of patients who had open salvage surgery showed evidence of cartilage invasion at the AC. We concluded that laryngeal AC cancers are more likely to invade the cartilage, and that anatomic risk factors are not the main cause of irradiation failure.

    Prospective study of 29 patients who underwent anterior cervical (AC) or posterior lumbar (PL) spinal surgery. A validated measure of dysphagia, the Swallowing-Quality of Life (SWAL-QOL) survey, was used to assess the degree of postoperative dysphagia. To determine the degree of dysphagia preoperatively and postoperatively in patients undergoing AC surgery compared with a control group that underwent PL surgery. Dysphagia is a well-known complication of AC spine surgery and has been shown to persist for up to 24 months or longer. A total of 18 AC patients and a control group of 11 PL patients were prospectively enrolled in this study and were assessed preoperatively and at 3 weeks and 1.5 years postoperatively using a 14-item questionnaire from the SWAL-QOL survey to determine degree of dysphagia. Other patient factors and anesthesia records were examined to evaluate their relationship to dysphagia. There were no significant differences between the AC and PL groups with respect to age, sex, body mass index, or length of surgery. The SWAL-QOL scores at 3 weeks were significantly lower for the AC group than for the PL group (76 vs. 96; P = 0.001), but there were no differences between the groups preoperatively or at final follow-up. Smokers, patients with chronic obstructive pulmonary disease, and women had lower SWAL-QOL scores at one or more time point. Patients undergoing AC surgery had a significant increase in the degree of dysphagia 3 weeks after surgery compared with patients undergoing PL surgery. By final follow-up, swallowing in the AC group recovered to a level similar to preoperative and comparable to that in patients undergoing lumbar surgery at 1.5 years. Smoking, chronic obstructive pulmonary disease, and female sex are possible factors in the development of postoperative dysphagia.

    To evaluate the morbidity of ambulatory repair of anterior hypospadias with a transurethral vesical catheter (TUVC) draining the urine between 2 diapers. 34 children divided into two comparable groups were operated for anterior hypospadias. Group A comprised 17 children operated by ambulatory surgery, with catheter drainage of urine between 2 diapers. Group B consisted of 17 children operated by a conventional inpatient procedure, with the catheter connected to a urine collector. Postoperative complications and the results of a satisfaction questionnaire sent to the parents of children in group A are reported. In group A, one case of TUVC dysfunction was reported and 13 parents declared to be satisfied. One urethral fistula occurred in group B. Ambulatory repair of anterior hypospadias with TUVC draining urine between 2 diapers does not induce a higher complication rate than when repair is performed by conventional hospitalisation with the TUVC connected to a urine collector. Urine drainage by TUVC is not a contraindication to ambulatory surgical repair of anterior hypospadias in children.

    Multicenter analysis of 2 groups of patients surgically treated for Lenke 5C adolescent idiopathic scoliosis (AIS). Compare patients with Lenke 5C scoliosis surgically treated with anterior spinal fusion with dual rod instrumentation and anterior column support with patients surgically treated with posterior release and pedicle screw instrumentation. Treatment of single, structural, lumbar, and thoracolumbar curves in patients with AIS has been the subject of some debate. Advocates of the anterior approach assert that their technique spares posterior musculature and may save distal fusion levels, and that with dual rods and anterior column support the issues with nonunion and kyphosis have been obviated. Advocates of the posterior approach assert that with the change to posterior pedicle screw based instrumentation that correction and levels are equivalent, and the posterior approach avoids the issues with nonunion and kyphosis. This report directly compares the results of posterior versus anterior instrumented fusions in the operative treatment of adolescent idiopathic Lenke 5C curves. We analyzed 62 patients with Lenke 5C based on radiographic and clinical data at 2 institutions: 31 patients treated with posterior, pedicle-screw instrumented fusions at 1 institution (group PSF); and 31 patients with anterior, dual-rod instrumented fusions at another institution (group ASF). Multiple clinical and radiographic parameters were evaluated and compared. The mean age, preoperative major curve magnitude, and preoperative lowest instrumented vertebral (LIV) tilt were similar in both groups (age: PSF = 15.5 years, ASF = 15.6 years; curve size: PSF = 50.3 degrees +/- 7.0 degrees , ASF = 49.0 degrees +/- 6.6 degrees ; LIV tilt: PSF = 27.5 degrees +/- 6.5 degrees , ASF = 27.8 degrees +/- 6.2 degrees ). After surgery, the major curve corrected to an average of 6.3 degrees +/- 3.2 degrees (87.6% +/- 5.8%) in the PSF group, compared with 12.1 degrees +/- 7.4 degrees (75

    Background: Abnormal joint motion has been linked to joint arthrosis after anterior cruciate ligament (ACL) reconstruction. However, the relationships between the graft properties (ie, structural and anatomic) and extent of posttraumatic osteoarthritis are not well defined. Hypotheses: (1) The structural (tensile) and anatomic (area and alignment) properties of the reconstructed graft or repaired ACL correlate with the total cartilage lesion area 1 year after ACL surgery, and (2) side-to-side differences in anterior-posterior (AP) knee laxity correlate with the total cartilage lesion area 1 year postoperatively. Study Design: Controlled laboratory study. Methods: Sixteen minipigs underwent unilateral ACL transection and were randomly treated with ACL reconstruction or bridge-enhanced ACL repair. The tensile properties, cross-sectional area, and multiplanar alignment of the healing ACL or graft, AP knee laxity, and cartilage lesion areas were assessed 1 year after surgery. Results: In the reconstructed group, the normalized graft yield and maximum failure loads, cross-sectional area, sagittal and coronal elevation angles, and side-to-side differences in AP knee laxity at 60° of flexion were associated with the total cartilage lesion area 1 year after surgery (R 2 > 0.5, P 0.5, P ligament or graft and AP laxity values were closer to those of the contralateral ACL-intact knee. Reconstructed grafts had a significantly larger normalized cross-sectional area and sagittal elevation angle (more vertical) when compared with repaired ACLs (P < .02). Conclusion: The tensile properties, cross-sectional area, and multiplanar alignment of the healing ACLs or grafts and AP knee laxity in reconstructed knees were associated with the extent of tibiofemoral cartilage damage after ACL surgery. Clinical Relevance: These data highlight the need for novel ACL injury treatments that can restore the structural and anatomic properties of the torn ACL to those of the native ACL in an

    Flapless implant placement using surgical templates may guarantee predictable and esthetic results provided that preplanned implant positions are transfered precisely into surgical reality. The study aims to investigate the effect of three-dimensional accuracy in guided implant surgery on the esthetic outcome of single-tooth implants in the anterior maxilla. Single-tooth implants for delayed replacement of upper incisors were inserted in 27 patients using stereolithographic templates. Superimposition of postoperative cone beam computed tomography (CBCT) scans allowed assessment of positional inaccuracy at the implant shoulder and apex, as well as angular deviation. Objective evaluation of implant esthetics was performed after a mean follow-up of 2.3 years using the Pink Esthetic Score (PES). Mean deviation between planned and actual implant position was 0.84 mm at the implant shoulder and significantly correlated to average PES of 12 (p = .031). Inaccuracy toward the buccal side was most frequent (70%). Deviations  ≥  0.8  mm resulted in significantly worse implant esthetics (median PES: 9.5, interquartile range [IQR]: 8-11) compared with more accurate implant positions (median PES: 13, IQR: 12-13, p = .039). Positional inaccuracy is low in guided implant surgery, but may however significantly compromise implant esthetics in the anterior maxilla. © 2014 Wiley Periodicals, Inc.

    Anterior cruciate ligament tears can lead to posttraumatic osteoarthritis. In addition to biomechanical factors, changes in biochemical profiles within the knee joint after injury and anterior cruciate ligament reconstruction (ACLR) may play a role in accelerating joint degeneration. Hypothesis/Purpose: It was hypothesized that cartilage matrix composition after ACLR is associated with the degree of inflammatory response after initial injury. This study evaluated the association between the inflammatory response after injury-as indicated by cytokine, metalloproteinase, and cartilage degradation marker concentrations in synovial fluid-and articular cartilage degeneration, measured by T1ρ and T2 quantitative magnetic resonance imaging up to 3 years after ACLR. Cohort study; Level of evidence, 2. Twenty-six subjects from a longitudinal cohort study who underwent ACLR at a mean 8.5 weeks after injury (range, 4-19 weeks) had synovial fluid aspirated at the time of surgery. Immunoassays quantified biomarkers in synovial fluid. T1ρ and T2 values of articular cartilage were calculated with magnetic resonance scans acquired prior to surgery and at 6 months and 1, 2, and 3 years after surgery. Pearson correlation coefficients were calculated among the various biomarkers. K-means clustering was used to group subjects with similar biomarker profiles. Generalized estimating equations were used to find the overall differences in T1ρ and T2 values throughout these first 3 years after surgery between the clusters while controlling for other factors. Significant and strong correlations were observed between several cytokines (interleukin 6 [IL-6], IL-8, IL-10, and tumor necrosis factor α) and 2 matrix metalloproteinases (MMP-1 and MMP-3) ( P matrix protein, and sulfated glycosaminoglycan ( P values in the medial tibial and patellar cartilage over the first 3 years after ACLR.

    Although dysphagia is a common complication after anterior cervical decompression and fusion, important risk factors have not been rigorously evaluated. Furthermore, the impact of dysphagia on neurological and quality-of-life outcomes is not fully understood. The aim of this study was to determine the prevalence of and risk factors for dysphagia, and the impact of this complication on short and long-term clinical outcomes, in patients treated with anterior cervical decompression and fusion. Four hundred and seventy patients undergoing a 1-stage anterior or 2-stage anteroposterior cervical decompression and fusion were enrolled in the prospective AOSpine CSM (Cervical Spondylotic Myelopathy) North America or International study at 26 global sites. Logistic regression analyses were conducted to determine important clinical and surgical predictors of perioperative dysphagia. Preoperatively and at each follow-up visit, patients were evaluated using the modified Japanese Orthopaedic Association scale (mJOA), Nurick score, Neck Disability Index (NDI), and Short Form-36 Health Survey (SF-36). A 2-way repeated-measures analysis of covariance was used to evaluate differences in outcomes at 6 and 24 months between patients with and those without dysphagia, while controlling for relevant baseline characteristics and surgical factors. The overall prevalence of dysphagia was 6.2%. Bivariate analysis showed the major risk factors for perioperative dysphagia to be a higher comorbidity score, older age, a cardiovascular or endocrine disorder, a lower SF-36 Physical Component Summary score, 2-stage surgery, and a greater number of decompressed levels. Multivariable analysis showed patients to be at an increased risk of perioperative dysphagia if they had an endocrine disorder, a greater number of decompressed segments, or 2-stage surgery. Both short and long-term improvements in functional, disability, and quality-of-life scores were comparable between patients with and those

However, there are few studies on the usefulness of hair thinning by intense pulsed light (IPL after hairline correction surgery in East Asian females.MethodsHair thinning using IPL was performed in 54 women who had complained about thick hairs along the frontal hairline after hairline correction surgery. Patient mean age was 31.2 years old and patients were an average of 2.1 years post-hairline correction surgery. Initial treatment used 10 J, while second and third sessions were conducted with 10 to 15 J according to responsiveness to treatment.ResultsMean thickness of individual hairs assessed before the procedure was 78.86 µm. The mean number of procedures was 1.6 per patient. Forty of 54 subjects (74% achieved satisfactory hair thinning with only one procedure from 78.01 to 66.14 µm after treatment. The measured thickness was 66.43 µm at the end of the first year in patients who were satisfied after one procedure. Thirteen cases achieved satisfactory hair thinning after two sessions. Mean thickness was 74.44 µm and 67.51 µm, before and after the second session. One case required a third session with 15J, thinning from 89.00 to 66.50 µm.ConclusionsHair thinning by IPL is a very useful method to provide a natural look after hairline correction surgery in East Asians, who have naturally thick hair.

    The purpose of this study was to evaluate the long-term isokinetic muscle performance after ACL surgery and to analyze by a multiple stepwise regression which factors (if any) predict the overall outcome. The study subjects were 119 patients who had a complete rupture of the ACL and had been treated surgically at the Tampere University Hospital between 1981 and 1990. They were divided into the acute group (N = 62) and into the chronic group (N = 57) according to the time delay between the injury and the ACL surgery. The isokinetic strength measurements of the quadriceps and hamstring muscles were performed on average 4 years after the operation using Cybex II and Cybex 6000 dynamometers (Lumex Inc., Ronkokoma, NY, USA). The peak torques were determined at speeds of 60 and 180 degrees/s and the peak work at speed of 180 degrees/s. The measurements revealed that after the ACL surgery there was still a considerable thigh muscle strength deficit especially in extension of the injured extremity, the average extension strength deficit ranging from 9 to 20%. The extension strength deficit was significantly more prominent in the chronic (18-20%) than in the acute group (9-15%). The extension strength deficit was significantly greater ar the slower (15-20%) than higher (9-18%) speed of the isokinetic movement. In both the acute and chronic groups, a multiple stepwise regression analysis indicated that patellofemoral pain and flexion deficit of the knee were the factors that most frequently and significantly associated with the strength deficits. At the higher speed of the isokinetic movement, these two factors accounted 20% and 21% for the variation seen in the quadriceps strength deficit of the acute group and the chronic group. No correlation could be found between age, sex, height, weight, body mass index, length of the follow-up time, injury type, athletic activity level, immobilization method, knee stability, and the isokinetic muscular performance.

    Effective analgesia after midline laparotomy surgery is essential for enhanced recovery programs. We compared three types of continuous abdominal wall block for analgesia after midline laparotomy for gynaecological oncology surgery. We conducted a single-centre, double-blind randomised controlled trial. Ninety-four patients were randomised into three groups to receive two days of programmed intermittent boluses of ropivacaine (18 ml 0.5% ropivacaine every four hours) via either a transversus abdominis plane (TAP) catheter, posterior rectus sheath (PRS) catheter, or a subcutaneous (SC) catheter. All groups received patient-controlled analgesia with morphine, and regular paracetamol and non-steroidal anti-inflammatory medication. Measured outcomes included analgesic and antiemetic usage and visual analog scores for pain, nausea, vomiting, and satisfaction. Eighty-eight patients were analysed (29 SC, 29 PRS and 30 TAP). No differences in the primary outcome were found (median milligrams morphine usage on day two SC 28, PRS 25, TAP 21, P =0.371). There were differences in secondary outcomes. Compared with the SC group, the TAP group required less morphine in recovery (0 mg versus 6 mg, P =0.01) and reported less severe pain on day one (visual analog scores 36.3 mm versus SC 55 mm, P =0.04). The TAP group used fewer doses of tropisetron on day one compared with the PRS group (8 versus 21, P =0.016). Programmed intermittent boluses of ropivacaine delivered via PRS, TAP and SC catheters can be provided safely to patients undergoing midline laparotomy surgery. Initially TAP catheters appear superior, reducing early opioid and antiemetic requirements and severe pain, but these advantages are lost by day two.

However, a comparable (–0.323±0.099 and not significantly different (p>0.09 level of RI reduction occurred in the second typological group. In the fourth typological group (20 cases, the maximum RI drop in medial branch of short posterior ciliary artery was –0.228±0.071.Conclusion: The results of this study suggest that the use of the Alloplant biomaterial in treating patients with AION consequencesimproves blood flow in vessels of the optic nerve (in the central retinal artery and more in short posterior ciliary artery with its branches and can be recommended as a fairly effective AION treatment.

    To assess the quality and variability found across anterior cruciate ligament (ACL) rehabilitation protocols published online by academic orthopaedic programs. Web-based ACL physical therapy protocols from United States academic orthopaedic programs available online were included for review. Main exclusion criteria included concomitant meniscus repair, protocols aimed at pediatric patients, and failure to provide time points for the commencement or recommended completion of any protocol components. A comprehensive, custom scoring rubric was created that was used to assess each protocol for the presence or absence of various rehabilitation components, as well as when those activities were allowed to be initiated in each protocol. Forty-two protocols were included for review from 155 U.S. academic orthopaedic programs. Only 13 protocols (31%) recommended a prehabilitation program. Five protocols (12%) recommended continuous passive motion postoperatively. Eleven protocols (26%) recommended routine partial or non-weight bearing immediately postoperatively. Ten protocols (24%) mentioned utilization of a secondary/functional brace. There was considerable variation in range of desired full-weight-bearing initiation (9 weeks), as well as in the types of strength and proprioception exercises specifically recommended. Only 8 different protocols (19%) recommended return to sport after achieving certain strength and activity criteria. Many ACL rehabilitation protocols recommend treatment modalities not supported by current reports. Moreover, high variability in the composition and time ranges of rehabilitation components may lead to confusion among patients and therapists. Level II.

    Full Text Available OBJETIVO: A cirurgia torácica vídeo-assistida (CTVA tem sido uma intervenção de escolha para o tratamento de pneumotórax espontâneo (PS com bolha pulmonar. Nosso objetivo foi apresentar uma abordagem de CTVA uniportal unilateral para bulectomia bilateral e avaliar sua eficácia terapêutica. MÉTODOS: Entre maio de 2011 e janeiro de 2012, cinco pacientes foram submetidos a bulectomia bilateral por essa abordagem. Todos apresentavam PS bilateral. A TCAR pré-operatória mostrou que todos os pacientes tinham bolhas bilaterais no pulmão apical. As indicações cirúrgicas, os procedimentos de operação e os desfechos foram revisados. RESULTADOS: Todos os pacientes foram submetidos com sucesso a essa abordagem para bulectomia bilateral, sem complicações intraoperatórias. A mediana de tempo para a retirada do dreno torácico foi de 4,2 dias, e a mediana do tempo de hospitalização no pós-operatório foi de 5,2 dias. A mediana de seguimento pós-operatório foi de 11,2 meses. Um paciente teve recidiva de PE do lado esquerdo três semanas após a cirurgia e foi submetido a abrasão pleural. CONCLUSÕES: A bulectomia bilateral utilizando CTVA uniportal combinada com acesso contralateral ao mediastino anterior é tecnicamente confiável e promove desfechos favoráveis para pacientes com PS que desenvolvem bolhas bilaterais no pulmão apical. Entretanto, para a realização desse procedimento cirúrgico, são necessários cirurgiões com experiência em CTVA, instrumentos toracoscópicos longos, entre outras exigências.OBJECTIVE: Video-assisted thoracoscopic surgery (VATS has been a surgical intervention of choice for the treatment of spontaneous pneumothorax (SP with lung bulla.

    The incidence of symptomatic adjacent segment disease (ASD) after anterior cervical diskectomy and fusion (ACDF) was reported as 2.9%/y in a previous cohort of 374 patients. Few other data corroborate the incidence and natural history of ASD. To calculate the incidence of ASD after ACDF that required secondary fusion surgery. The retrospective study used an 11-year nationwide database to analyze the incidences. All patients who underwent ACDF for cervical disk diseases were identified through diagnostic and procedure codes. Kaplan-Meier and Cox regression analyses were performed. From 1997 to 2007, covering 241 800 725.8 person-years, 19 385 patients received ACDF and 568 had ≥ 2 ACDF operations. The incidence of secondary ACDF operations was 7.6 per 1000 person-years. At the end of the 10-year cohort, 94.4% of patients who had received 1 ACDF remained free from secondary ACDF. The average time interval between the first and second ACDF was 23.3 months. After adjustment for comorbidities and socioeconomic status, secondary ACDF operations were more likely performed on male patients (hazard ratio = 1.27; P = .008) 15 to 39 years of age (hazard ratio = 1.45; P = .009) and 40 to 59 years of age (hazard ratio = 1.41, P = .002, respectively). Repeat ACDF surgery for ASD cumulated steadily in an annual incidence of approximately 0.8%, much lower than the reported incidence of symptomatic ASD. However, at the end of this 10-year cohort, a considerable portion of patients (5.6%) received a second operation. Younger and male patients are more likely to receive such second operations.

    Hamstring muscles play a major role in knee-joint stabilization after anterior cruciate ligament (ACL) injury. Weakness of the knee extensors after ACL reconstruction with patellar tendon (PT) graft, and in the knee flexors after reconstruction with hamstring tendons (HT) graft has been observed up to 2 years post surgery, but not later. In these studies, isokinetic muscle torque was used. However, muscle power has been suggested to be a more sensitive and sport-specific measures of strength. The aim was to study quadriceps and hamstring muscle power in patients with ACL injury treated with surgical reconstruction with PT or HT grafts at a mean of 3 years after surgery. Twenty subjects with PT and 16 subjects with HT grafts (mean age at follow up 30 years, range 20-39, 25% women), who were all included in a prospective study and followed the same goal-based rehabilitation protocol for at least 4 months, were assessed with reliable, valid, and responsive tests of quadriceps and hamstring muscle power at 3 years (SD 0.9, range 2-5) after surgery. The mean difference between legs (injured minus uninjured), the hamstring to quadriceps (H:Q, hamstring divided by quadriceps) ratio, and the limb symmetry index (LSI, injured leg divided by uninjured and multiplied by 100) value, were used for comparisons between the groups (analysis of variance). The mean difference between the injured and uninjured legs was greater in the HT than in the PT group for knee flexion power (-21.3 vs. 7.7 W, p = 0.001). Patients with HT graft had lower H:Q ratio in the injured leg than the patients with PT graft (0.63 vs. 0.77, p = 0.012). They also had lower LSI for knee flexion power than those in the PT group (88 vs. 106%, p hamstring muscle power, and the lower hamstring to quadriceps ratio in the HT graft group than in the PT graft group 3 years (range 2-5) after ACL reconstruction, reflect imbalance of knee muscles after reconstruction with HT graft that may have a negative effect on

    Non-arteritic posterior ischemic optic neuropathy (NA-PION) is a disorder involving reduced blood flow to the retrobulbar portion of the optic nerve. This disorder usually develops acutely, and research has suggested that high-dose steroid therapy soon after the onset of visual loss can result in significant visual improvement. This treatment, however, is not universally successful. The addition of a potent vasodilator could help to restore ocular blood flow. This case report describes the use of prostaglandin E1 (PGE1), a powerful vasodilator of the microcirculation, to treat three separate episodes of NA-PION over five years in the same patient. A 68-year-old white male was first seen in June 2009 with NA-PION in the left eye, and the condition was treated with steroids and PGE1. The patient had a subsequent episode in July 2010 that was treated with steroids and PGE1 and another in May 2014 that was treated with PGE1 alone. Visual acuity improved from 4/10 to 11/10 in 2009, from 4/10 to 11/10 in 2010, and from 5/10 to 10/10 in 2014. No complications due to the use of PGE1 were noted. PGE1 should be considered as a treatment for NA-PION to immediately restore blood flow and potentially improve vision.

    It is well known that arthrodesis is associated with adjacent segment degeneration (ASD). However, previous studies were performed with simple radiography or CT. MRI is most sensitive in assessing the degenerative change of a disc, and this is the first study about ASD by radiography, CT and MRI. We sought to factors related to ASD at cervical spine by an MRI and CT, after anterior cervical spine surgery. This is a retrospective cross-sectional study of cervical disc herniation. Patients of cervical disc herniation with only radiculopathy were treated with either arthroplasty (22 patients) or ACDF with cage alone (21 patients). These patients were required to undergo MRI, CT and radiography preoperatively, as well as radiography follow-up for 3 months and 1 year, and we conducted a cross-sectional study by MRI, CT and radiography including clinical evaluations 5 years after. Clinical outcomes were assessed using VAS and NDI. The fusion rate and ASD rate, and radiologic parameters (cervical lordosis, operated segmental height, C2-7 ROM, operated segmental ROM, upper segmental ROM and lower segmental ROM) were measured. The study groups were demographically similar, and substantial improvements in VAS (for arm) and NDI (for neck) scores were noted, and there were no significant differences between groups. Fusion rates were 95.2% in the fusion group and 4.5% in the arthroplasty group. ASD rates of the fusion and arthroplasty groups were 42.9 and 50%, respectively. Among the radiologic parameters, operated segmental height and operated segmental ROM significantly decreased, while the upper segmental ROM significantly increased in the fusion group. In a comparative study between patients with ASD and without ASD, the clinical results were found to be similar, although preexisting ASD and other segment degeneration were significantly higher in the ASD group. C2-7 ROM was significantly decreased in ASD group, and other radiologic parameters have no significant differences

    Cooling of local anesthetic potentiates its action and increases its duration. Magnesium sulfate (MgSo 4 ) added to local anesthetic prolongs the duration of anesthesia and postoperative analgesia with minimal side effects. The aim of this prospective, randomized, double-blind study was to compare the effect of cold to 4°C bupivacaine 0.5% and Mg added to normal temperature (20-25°C) bupivacaine 0.5% during sonar-guided combined femoral and sciatic nerve blocks on the onset of sensory and motor block, intraoperative anesthesia, duration of sensory and motor block, and postoperative analgesia in arthroscopic anterior cruciate ligament (ACL) reconstruction surgery. A total of 90 American Society of Anesthesiologists classes I and II patients who were scheduled to undergo elective ACL reconstruction were enrolled in the study. The patients were randomly allocated to 3 equal groups to receive sonar-guided femoral and sciatic nerve blocks. In Group I, 17 ml of room temperature (20-25°C) 0.5% bupivacaine and 3 ml of room temperature saline were injected for each nerve block whereas in Group II, 17 ml of cold (4°C) 0.5% bupivacaine and 3 ml of cold saline were injected for each nerve block. In Group III, 17 ml of room temperature 0.5% bupivacaine and 3 ml of MgSo 4 5% were injected for each nerve block. The onset of sensory and motor block was evaluated every 3 min for 30 min. Surgery was started after complete sensory and motor block were achieved. Intraoperatively, the patients were evaluated for heart rate and mean arterial pressure, rescue analgesic and sedative requirements plus patient and surgeon satisfaction. Postoperatively, hemodynamics, duration of analgesia, resolution of motor block, time to first analgesic, total analgesic consumption, and the incidence of side effects were recorded. There was no statistically significant difference in demographic data, mean arterial pressure, heart rate, and duration of surgery. Onset of both sensory and motor block was

    The highest incidence of olfactory dysfunction following a pterional approach and its modifications for an intracranial aneurysm has been reported in cases of anterior communicating artery (ACoA) aneurysms. The radiological characteristics of unruptured ACoA aneurysms affecting the extent of retraction of the frontal lobe and olfactory nerve were investigated as risk factors for postoperative olfactory dysfunction. A total of 102 patients who underwent a pterional or superciliary keyhole approach to clip an unruptured ACoA aneurysm from 2006 to 2013 were included in this study. Those patients who complained of permanent olfactory dysfunction after their aneurysm surgery, during a postoperative office visit or a telephone interview, were invited to undergo an olfactory test, the Korean version of the Sniffin' Sticks test. In addition, the angiographic characteristics of ACoA aneurysms, including the maximum diameter, the projecting direction of the aneurysm, and the height of the neck of the aneurysm, were all recorded based on digital subtraction angiography and sagittal brain images reconstructed using CT angiography. Furthermore, the extent of the brain retraction was estimated based on the height of the ACoA aneurysm neck. Eleven patients (10.8%) exhibited objective olfactory dysfunction in the Sniffin' Sticks test, among whom 9 were anosmic and 2 were hyposmic. Univariate and multivariate analyses revealed that the direction of the ACoA aneurysm, ACoA aneurysm neck height, and estimated extent of brain retraction were statistically significant risk factors for postoperative olfactory dysfunction. Based on a receiver operating characteristic (ROC) analysis, an ACoA aneurysm neck height > 9 mm and estimated brain retraction > 12 mm were chosen as the optimal cutoff values for differentiating anosmic/hyposmic from normosmic patients. The values for the area under the ROC curves were 0.939 and 0.961, respectively. In cases of unruptured ACoA aneurysm surgery, the

    Prospective randomized study. To investigate differences in physical functional outcome in patients with radiculopathy due to cervical disc disease, after structured physiotherapy alone (consisting of neck-specific exercises with a cognitive-behavioral approach) versus after anterior cervical decompression and fusion (ACDF) followed by the same structured physiotherapy program. No earlier studies have evaluated the effectiveness of a structured physiotherapy program or postoperative physical rehabilitation after ACDF for patients with magnetic resonance imaging-verified nerve compression due to cervical disc disease. Our prospective randomized study included 63 patients with radiculopathy and magnetic resonance imaging-verified nerve root compression, who were randomized to receive either ACDF in combination with physiotherapy or physiotherapy alone. For 49 of these patients, an independent examiner measured functional outcomes, including active range of neck motion, neck muscle endurance, and hand-related functioning before treatment and at 3-, 6-, 12-, and 24-month follow-ups. There were no significant differences between the 2 treatment alternatives in any of the measurements performed (P = 0.17-0.91). Both groups showed improvements over time in neck muscle endurance (P ≤ 0.01), manual dexterity (P ≤ 0.03), and right-handgrip strength (P = 0.01). Compared with a structured physiotherapy program alone, ACDF followed by physiotherapy did not result in additional improvements in neck active range of motion, neck muscle endurance, or hand-related function in patients with radiculopathy. We suggest that a structured physiotherapy program should precede a decision for ACDF intervention in patients with radiculopathy, to reduce the need for surgery. 2.

    To determine if the use of cardiopulmonary bypass is associated with all-cause in-hospital and mid-term survival for patients undergoing left internal mammary artery (LIMA) to left anterior descending (LAD) coronary artery bypass grafting (CABG) for single coronary vessel disease. Data from the National Adult Cardiac Surgery Audit registry for all elective and urgent isolated CABG procedures performed between April 2003 and March 2013 in first-time cardiac surgery patients were extracted. Experienced surgeons (those with ≥300 records) were classified by their technique preference (as 'off-pump preference', 'mixed practice', 'on-pump preference') based on their entire isolated CABG data. In-hospital mortality and time to death were analysed using logistic and Cox proportional hazards regression models, respectively. From a total of 3402 records, 65.5% were performed off-pump. There were 16 (0.47%) in-hospital deaths: 6 (0.51%) in the on-pump group and 10 (0.45%) in the off-pump group. The risk-adjusted odds ratio of in-hospital mortality in the direction of on-pump was 1.09 [95% confidence interval (CI): 0.39-3.04; P = 0.86]. The overall 5-year survival in the on- and off-pump groups was 93.1 and 93.4%, respectively. The adjusted hazard ratio (HR) for mortality in the direction of on-pump CABG was 1.15 (95% CI: 0.89-1.49; P = 0.28). Comparing off-pump cases performed by experienced CABG surgeons with a preference for the off-pump technique with on-pump cases performed by surgeons with a preference for the on-pump technique indicated a significant difference (HR for on-pump = 1.72; 95% CI: 1.19-2.47; P = 0.004). Elective and urgent first-time CABG for isolated LAD disease is associated with excellent mid-term survival in the England and Wales population, conferring a 5-year survival rate of 93.1 and 93.4% in the on-pump and off-pump groups, respectively. There was no difference in risk-adjusted survival between the on-pump and off-pump techniques when analysing all

    To investigate the association between surgical variables and the risk of revision surgery after ACL reconstruction in the Swedish National Knee Ligament Register. This cohort study was based on data from the Swedish National Knee Ligament Register. Patients who underwent primary single-bundle ACL reconstruction with hamstring tendon were included. Follow-up started with primary ACL reconstruction and ended with ACL revision surgery or on 31 December, 2014, whichever occurred first. Details on surgical technique were collected using an online questionnaire. All group comparisons were made in relation to an "anatomic" reference group, comprised of essential AARSC items, defined as utilization of accessory medial portal drilling, anatomic tunnel placement, visualization of insertion sites and pertinent landmarks. Study end-point was revision surgery. A total of 108 surgeons (61.7%) replied to the questionnaire. A total of 17,682 patients were included [n = 10,013 males (56.6%) and 7669 females (43.4%)]. The overall revision rate was 3.1%. Older age as well as cartilage injury evident at index surgery was associated with a decreased risk of revision surgery. The group using transtibial drilling and non-anatomic bone tunnel placement was associated with a lower risk of revision surgery [HR 0.694 (95% CI 0.490-0.984); P = 0.041] compared with the anatomic reference group. The anatomic reference group showed no difference in risk of revision surgery compared with the transtibial drilling groups with partial anatomic [HR 0.759 (95% CI 0.548-1.051), n.s.] and anatomic tunnel placement [HR 0.944 (95% CI 0.718-1.241), n.s.]. The anatomic reference group showed a decreased risk of revision surgery compared with the transportal drilling group with anatomic placement [HR 1.310 (95% CI 1.047-1.640); P = 0.018]. Non-anatomic bone tunnel placement via transtibial drilling resulted in the lowest risk of revision surgery after ACL reconstruction. The risk of revision surgery

    The purpose of this study was to investigate the incidence and causes of non-fusion segment disease (NFSD), both adjacent and non-adjacent to a fused segment, after anterior cervical arthrodesis. This is a single-center study. Between January 1998 and January 2011, two surgeons' 171 patients who had an anterior cervical decompression and fusion were followed clinically for more than 5 years. The correlation between the incidence of symptomatic non-fusion segment disease and the following clinical parameters (age at operation, fusion levels,) and radiological parameters (number of patients who had a plate, anterior cervical decompression and fusion (ACDF) or corpectomies, preoperative and postoperative cervical spine alignment, Pavlov's ratio at the C5 level, and preoperative existence of a non-fusion segment degeneration on magnetic resonance imaging) was evaluated. Of the 171 patients reviewed, 16 patients had non-fusion segment disease (9.36%), of which 12 had adjacent segment disease and 4 had non-adjacent segment disease. Postoperative cervical lordosis in the non-fusion segment disease group was significantly smaller than that of the disease-free group (P Fusion levels in the NFSD group were 1.69 whereas 2.26 in disease-free group (P = 0.005). The incidences of disc degeneration in unfused segments was more severe in the NFSD group than in the disease-free group (P = 0.004). The results of binary logistic regression showed that the major factor affecting NFSD is postoperative cervical lordosis (P = 0.000) followed by disc degeneration (P = 0.024). The other parameters did not show a statistically significant difference. The incidence of symptomatic non-fusion segment disease after anterior cervical arthrodesis has multifactorial causes. Postoperative cervical lordosis and disc degeneration in non-fusion segments were major factors in the incidence of NFSD.

    Multicenter matched case analysis. Compare patients with Lenke 5C scoliosis surgically treated with anterior spinal fusion with dual rod instrumentation and anterior column support versus posterior release and pedicle screw instrumentation. Treatment of single, structural, lumbar and thoracolumbar curves in patients with adolescent idiopathic scoliosis (AIS) has been the subject of some debate. Previous papers directly comparing these approaches are problematic because of heterogeneity of the groups, nonrandomized protocols, and surgeon bias and variation of instrumentation (upper instrumented vertebrae and lower instrumented vertebrae) in relation to the defined Cobb angle (upper end vertebra and lower end vertebrae). This report sought to remedy these flaws by analyzing a database of Lenke 5C AIS and performing matched cases. We analyzed 96 patients with Lenke 5C AIS curves based on radiographic and clinical data at 3 institutions, surgically treated between 2001 and 2005 with minimum 2-year follow-up. Case matched criteria (age within 1 year, sex, curve within 5°, lower end vertebrae, and lower instrumented vertebrae) yielded 21 matched patient pairs. We evaluated and compared multiple clinical and radiographic parameters. We observed no significant statistical differences between groups in any preoperative clinical or radiographic parameters. At final follow-up, the major curve measured 8° (83%) in the posterior spinal fusion group, compared with 13° (72%) in the anterior spinal fusion group (p = .002). Estimated blood loss was similar in both groups. Hospital stay was significantly shorter in the posterior spinal fusion group. There were no differences in radiographic complications, such as proximal junctional kyphosis. At a minimum of 2 years' follow-up in a multicenter, matched case analysis, adolescents with Lenke 5C curves demonstrated statistically significantly better curve correction and shorter hospital stays when treated with a posterior release

    The purpose of this investigation was to identify if supplemental vitamin E (consisting of α- and γ-tocopherol's) and C modulate serum cytokine and muscle strength following an ACL injury and surgery. Subjects were randomly assigned to one of two groups: (1) placebo (n=14) or (2) vitamins E (α-[600m g RRR-α-tocopherol, αT] and γ-[600 mg of RRR-γT]) and C (1000 mg ascorbic acid, AA) (EC; n=15). Supplements were taken daily starting ∼2-wk prior to and concluding 16-wk after surgery. Fasting blood samples were obtained and single-leg peak isometric force measurements were performed at baseline (prior to supplementation), before surgery (∼120-min - blood draw only), and 8-wk, 12-wk, and 16-wk after surgery. αT, γT, AA, and cytokines were measured in each blood sample, and peak isometric force was measured on the injured and non-injured legs separately at each testing session. An exercise protocol consisting of repetitive knee and hip extension and flexion contractions to exhaustion was performed on the injured limb at 16-wk. Vitamin E and C supplementation significantly (all pexercise protocol were not significantly different between groups. Based on these findings, we conclude that vitamin E and C supplementation increases their endogenous levels without minimizing muscular weakness or modulating serum cytokine concentrations after ACL surgery.

    Retrospective review of a consecutive, single surgeon case series. To compare minimum 2-year postoperative outcomes between 4.0-mm stainless steel and 4.75-mm titanium alloy single-rod anterior thoracoscopic instrumentation for the treatment of thoracic idiopathic scoliosis. Advances in anterior thoracoscopic spinal instrumentation for scoliosis have attempted to mitigate the postoperative complications of rod failure, pseudarthrosis, and deformity progression. Biomechanical data suggest that the 4.75-mm titanium construct has a lower risk of fatigue failure compared to the 4.0-mm stainless steel construct. Sixty-four consecutive anterior thoracoscopic spinal instrumentation cases in patients with thoracic scoliosis performed by a single surgeon and with minimum 2-year follow-up were retrospectively reviewed. The first 34 cases used a 4.0-mm stainless steel (SS) construct, whereas the subsequent 30 cases used a 4.75-mm titanium (Ti) alloy instrumentation system. The first 10 SS cases and the first 5 Ti cases were excluded from the statistical comparison to account for a potential learning curve effect. A multivariate analysis of variance (P 0.13). The average follow-up in the SS group was, however, significantly longer than in the Ti group (4.0 +/- 1.4 years vs. 2.3 +/- 1.0 years; P = 0.001). Preop main thoracic Cobb angles were similar between the 2 groups (P = 0.62); however, the 2-year main thoracic Cobb was significantly smaller (P = 0.03) and the 2-year percent correction was significantly greater in the Ti group (P = 0.03). Five patients (21%) in the SS group had a pseudarthrosis, 3 (13%) experienced rod failure, and 2 (8%) required a revision posterior spinal fusion. In the Ti group, 2 patients (8%) had a pseudarthrosis, and no patient experienced rod failure or required a revision procedure. Although the average follow-up in the Ti group was significantly shorter than in the SS group, the 4.75-mm titanium alloy construct resulted in improved maintenance of

    For many clinicians, their effectiveness is dependent on the magnitude of forces they manually apply to their patients. However, current state-of-the-art care strategies lack quantitative feedback, making it difficult to provide consistent care over time and among multiple clinicians. To provide real-time quantitative feedback to clinicians, we have developed a disposable glove with a force sensor embedded in the fingertips or palm. The sensor is based on the fiber-optic bendloss effect whereby light intensity from an infrared source is attenuated as the fiber is bent between a series of corrugated teeth. The sensor fabricated has a very low profile (10×7×1 mm) and has demonstrated high sensitivity, accuracy, range, and durability. Force feedback up to 90 N with an average force threshold at 0.19 N and average sensor resolution at 0.05 N has been demonstrated. A preliminary clinical study has also been conducted with anterior cruciate ligament reconstruction patients who show significant range of motion improvement when treated with the force-sensing glove.

    Based on long-term follow-ups, this study was designed to investigate the incidence and risk factors for postoperative adjacent segment degeneration (ASD) after anterior cervical discectomy and fusion (ACDF) or total disc replacement (TDR) in treating cervical degenerative diseases. Between January 2000 and December 2005, 108 cases undergoing ACDF and 78 undergoing TDR, were enrolled into this study. All medical records were retrospectively collected. Every patient was followed up at least 10 years. Outcome assessment included visual analogue scale (VAS) score, Neck Disability Index (NDI) score, Japanese Orthopaedic Association (JOA) score, and radiographic parameters. Consequently, thirty-eight (35.2%) of 108 cases suffered from ASD in ACDF group, and 26 (33.3%) of 78 cases in TDR group. There was no statistical difference between the two groups regarding ASD incidence, VAS/NDI/JOA score, recovery rate. Logistic regression analysis showed that age (OR = 2.86, 95% CI, 1.58-4.14) and preoperative segmental lordosis (OR = 1.90, 95% CI, 1.05-3.20) were risk factors associated with increased odds of ASD regardless of surgical procedures. On the other hand, preoperative overall lordosis (OR = 0.54, 95% CI, 0.26-0.82) was most likely protective. In conclusion, advanced age and preoperative segmental lordosis were identified as risk factors for postoperative ASD, while preoperative overall lordosis proves to be a protective factor.

    Doppler sonography can be used for real-time intraoperative localization of arteries within or near brain tumors but is less useful for distinguishing between arteries with similar diameters, such as the main trunk and branches of the anterior cerebral artery (ACA). By contrast, sononavigation provides real-time information in alignment with magnetic resonance imaging scans and may be of use in characterizing the identity of individual arteries on Doppler sonographic images. The goal of this study was to determine whether sononavigation can distinguish the main trunk of the ACA from the branches of the ACA on Doppler sonographic images. Doppler sonography was used in 3 patients undergoing surgical resection of brain tumors involving the main trunk of the ACA. The location of the main trunk of the ACA was characterized by sononavigation. With these data, tumor resection was performed with preservation of the main trunk of the ACA. Gross total resection was achieved in 1 case. Intraoperative sononavigation with Doppler sonography accurately localized the main trunk of the ACA and enabled preservation of this structure during tumor resection. This method may be applicable to the characterization of other critical arteries and may allow tumor resection with decreased morbidity.

  10. Use of Intravitreal Dexamethasone in a Case of Anterior Ischemic Optic Neuropathy

    Full Text Available Nowadays there is no unique and well-established treatment for nonarteritic anterior ischemic optic neuropathy, despite being the main acute pathology that affects the optic nerve in the elderly population and often resulting in a significant loss of visual acuity. The effectiveness of oral steroids is still under debate in the international literature, although many studies show that patients treated with high doses of systemic corticosteroids have a significantly higher chance of improved visual acuity and visual fields. The authors propose an intravitreal dexamethasone injection/implant as initial and acute therapy. Compared to systemic corticosteroids, intravitreal dexamethasone has the advantage of avoiding any systemic side effects of steroids. On the other hand, a rise in intraocular pressure might occur, manageable with local antiglaucoma drugs, especially in patients at risk, and there is a risk of induced cataract. The pharmacodynamics of the intravitreal dexamethasone slow-release implant is characterized by a first step with high release concentrations and a second following phase with decreasing concentrations. Therefore, the use of emergency dexamethasone (high concentration intravitreal injection is justified as a treatment after the first detection of an ischemic optic anterior neuropathy.

    The median sacral artery (MSA) is a relatively small vessel that always arises from the posterior, terminal part of the infrarenal aorta. In most cases, the MSA runs behind the iliocaval junction. Here, we describe a very rare case of an MSA running in front of this junction. During a human cadaveric dissection of the retroperitoneal area, we unexpectedly observed that the MSA passed in front of the left common iliac vein. The anatomy of the MSA has been extensively described and variations are quite rare. On the basis of this specific case, knowledge of the anatomic interactions between the MSA and other lumbar retroperitoneal vessels may help to avoid potential complications during surgery.

    In this study, a new modified surgical technique is presented for anatomic acromioclavicular (AC) joint reconstruction made by the application of anterior tibialis tendon autograft, three-way tunnel (two clavicular and one coracoid) and hook plate. The study is aimed to evaluate the post-operative short-term results of patients who underwent this treatment. A total of 11 patients underwent AC joint reconstruction because of persistent AC subluxation. In this reconstruction, a triple tunnel was made between the coracoid and the clavicle to anatomically restore the coracoclavicular (CC) ligament and an allograft was passed through the tunnels resembling conoid and trapezoid ligaments. The tendon had to be non-weight bearing at the appropriate tension to provide rapid and appropriate integration of the tendon in the tunnel. This was maintained by applying a hook plate. The hook plate method was used to protect the reconstructed ligament during the healing process as it has a similar hardness to that of the natural AC joint and provides rigid fixation. For a more comprehensive description of the technique, a cadaver demonstration was also performed. The mean follow-up period was 25.3 months (range: 18-34 month). None of the patients had a loss of reduction at the final follow-up. When the constant scores were examined, of the total 11 patients, 2 (18.2%) 38,39 had excellent results, 6 (54.5%) had good results and 3 (27.3%) had fair results. It can be seen that this newly described reconstruction technique has successful short-term results as an anatomic method and can be used effectively in revision cases. However, there is a need for further biomechanical and clinical studies to make comparisons with other techniques. PMID:24403760

    The ethmoid air cell labyrinth lies adjacent to the medial orbital wall, extending even beyond the sutures of the ethmoid bone. Its anatomic relationship to the lacrimal sac fossa is important in lacrimal surgery. We evaluated computed tomographic scans of 190 orbits with normal ethmoid anatomy to define the anatomic relationship of anterior ethmoid air cells to the lacrimal sac fossa. In 93% of the orbits, the cells extended anterior to the posterior lacrimal crest, with 40% entering the frontal process of the maxilla. This anatomic relationship may be used to facilitate the osteotomy during dacryocystorhinostomy. During a 10-year period (310 cases), one of us routinely entered the anterior ethmoid air cells to initiate the osteotomy during dacryocystorhinostomy. This technique has helped to avoid lacerations of the nasal mucosa.

    Full Text Available ABSTRACT We present the case of a 31-year-old patient with toxic anterior segment syndrome (TASS that developed after undergoing deep anterior lamellar keratoplasty (DALK. She had keratoconus, and despite wearing hard contact lenses for many years in the left eye, her vision had deteriorated; therefore, DALK was performed on this eye. The preoperative visual acuity (VA was finger counting at 3 m. Routine DALK was performed using the "big-bubble" technique. The corneal entry incision was hydrated at the end of the surgery, which was terminated by air injection into the anterior chamber. On postoperative day 1, VA was at the level of hand movements, and the cornea was edematous. Topical high-dose dexamethasone and oral steroids were initiated considering the diagnosis of TASS. Subsequently, the patient's VA increased, and the corneal edema decreased. We believe that the use of re-sterilized cannulas may have been the likely cause of TASS. Although DALK can be performed without interfering with the anterior chamber, one should keep in mind that TASS may occur in response to the solution used to hydrate the incision site and the air injected into the anterior chamber.

    Background Few studies have reported the safety and efficacy of hybrid surgery (HS), and some of the studies comparing HS with ACDF have reported conflicting results. We conducted this meta-analysis to clarify the advantages of HS in the treatment of multilevel cervical spondylosis. Material/Methods We performed a systematic literature search in PubMed, Medline, and CNKI to identify relevant controlled trials published up to October 2015. The standardized mean difference (SMD) and 95% confidence interval (95% CI) of the perioperative parameters, visual analogue scale pain score (VAS), neck disability index (NDI), and range of motion (ROM) of C2–C7 and adjacent segments were calculated. We also analyzed complications and Odom scale scores using risk difference (RD) and 95% CI. Results In total, 7 studies were included. The pooled data exhibited significant differences in blood loss between the 2 groups. However, there was no evidence indicating significant differences in operation time, complications, VAS, NDI, or Odom scale scores. Compared with the ACDF group, the HS group exhibited significantly protected C2-C7 ROM and reduced adjacent-segment ROM. Conclusions The safety of HS may be as good as that of ACDF. Furthermore, HS is superior to ACDF in conserving cervical spine ROM and decreasing adjacent-segment ROM. However, the results should be accepted cautiously due to the limitations of the study. Studies with larger sample sizes and longer follow-up periods are required to confirm and update the results of the present study. PMID:26709008

    Non-arteritic posterior ischemic optic neuropathy (NA-PION) is a disorder of reduced blood flow to the retrobulbar optic nerve. There is usually an acute loss of visual acuity and field. Previous studies have noted an improvement in visual acuity and in ocular and retrobulbar blood flow with the use of a potent vasodilator of the microcirculation, prostaglandin E1 (PGE1), and steroids. The current report describes immediate improvement in the visual fields and visual acuity in a patient with NA-PION treated with intravenous PGE1 and steroids 66 hours after onset. An 89-year-old white female was first seen in December 2016 with a sudden loss of vision in the right eye. After a complete eye exam and visual fields, the patient was diagnosed with NA-PION. Treatment was immediately started with steroids and intravenous PGE1. This was repeated once again the next morning. Visual acuity in the right eye improved from 1/10 + 1 to 7/10 + 3 at 5 days. The mean deviation of the visual field improved from - 7.10 decibels (dB) with a central scotoma of - 22 dB to - 2.97 dB with a central scotoma of - 19 dB. After 2 weeks, her visual acuity was 7/10 + 1 and visual field testing of the right eye revealed a mean deviation of - 2.54 dB with a central scotoma of - 9 dB. The left eye was unchanged. In cases of NA-PION, PGE1 and steroids should be considered to immediately restore blood flow to help improve visual acuity and visual fields.

    Full Text Available INTRODUÇÃO: A cirurgia de revascularização do miocárdio (RM sem circulação extracorpórea (CEC é uma técnica amplamente utilizada. A fluxometria coronariana é a técnica mais usada para avaliação dos enxertos, porém, poucos estudos comparam os dados fluxométricos na RM com e sem CEC. O objetivo deste estudo foi comparar as variáveis fluxométricas dos enxertos de artéria torácica interna esquerda para a artéria descendente anterior em pacientes submetidos à RM com e sem CEC. MÉTODOS: Entre março e setembro de 2010, foram analisados retrospectivamente 35 pacientes consecutivos, não randomizados, submetidos à RM. Foram alocados 10 pacientes no grupo A (com CEC e 25 no grupo B (sem CEC. O fluxo médio do enxerto (FME, o índice pulsátil (PI e a porcentagem de enchimento diastólico (ED foram obtidos por meio da fluxometria por tempo de trânsito. Foi utilizado o teste exato de Fisher e Mann-Whitney, sendo considerado estatisticamente significante PBACKGROUND: Off-pump coronary bypass grafting (OPCAB has become a widely used technique. Coronary flowmetry is the most common method employed to assess graft patency, nevertheless, few studies compare flow patterns between ONCAB and OPCAB surgery. The objective of this study was to compare flowmetry data in left internal mammary artery grafts bypasses to the left anterior descendent artery. METHODS: From March to September of 2010, thirtyfive consecutive, non-randomized patients underwent CABG and were retrospectively evaluated.

    The conventional method for preventing web formation after anterior glottic web surgery is keel insertion. However, this presents risks of airway compromise and granulation tissue formation, which could necessitate tracheotomy in addition to a secondary procedure for keel removal. We introduce a novel, 1-stage endoscopic laser anterior commissurotomy for preventing anterior glottic web re-formation. Twenty patients with glottic webs involving the anterior commissure were studied. The lesions were removed by transoral carbon dioxide laser microsurgery. In all patients, the anterior glottic web was vaporized along with the inner perichondrium of the thyroid cartilage over the anterior commissure area, creating a raw vertical break "alley" between the anterior vocal folds that measured between 0.3 and 0.5 cm in width and between 0.8 and 2 cm in length. The preoperative and postoperative vocal folds and voice quality were evaluated by videostrobolaryngoscopy and voice recordings. All 20 patients had anterior glottic webs ranging from 11% to 64% of the length from the anterior commissure to the vocal process. None of the patients developed restenosis at the anterior commissure of a severity similar to that of the initial lesion during follow-up (mean, 13 months; range, 3 to 44 months).All patients except 1 reported satisfaction with their voice improvement. Outcome analysis revealed that partial re-formation of the web was noted in 4 patients. One-stage, endoscopic laser anterior commissurotomy was effective and relatively safe for removing glottic webs, for preventing anterior glottic web re-formation, and for improving vocal fold performance among our patients.

  6. Anterior shoulder dislocations in sports.

    Aronen, J G

    1986-01-01

    Anterior shoulder dislocations, primary and recurrent, are among the most disabling injuries to the shoulder that can plague the athlete. The diagnosis is easily made by the following: the physical appearance of the shoulder; loss of capability by the athlete to internally and externally rotate the shoulder with the elbow at his side; by evaluating the mechanism of injury; and x-rays. Anterior shoulder dislocations should be reduced as soon as possible after diagnosis, to minimise the stretching effect on the neurovascular structures while the humeral head is dislocated. The reduction is not done to allow the athlete to return immediately to sport. Use of a simple traction method in the first 10 to 15 minutes following the injury will result in a successful reduction in the vast majority of dislocations. Reduction of the humeral head can be confirmed by the athlete regaining the capability to internally and externally rotate his shoulder with his elbow at his side. Following reduction, the athlete should begin a treatment regimen which includes a restrengthening programme emphasising the muscles of internal rotation and adduction plus rigid restrictions of activities until the goals of the rehabilitation programme are satisfied. The author's experience with this treatment regimen with athletes at the United States Naval Academy, has shown a decrease of the recurrence rate of primary anterior shoulder dislocations to 25% versus the 80% recurrence rate we have become familiar with from studies done which did not stress specific rehabilitation programmes. The athlete should also be instructed in a self-performed traction method for reduction should a redislocation occur, to minimise the stretching effect on the neurovascular structures and allow relief from discomfort. Surgery for primary and recurrent anterior dislocations should only be considered when the athlete fails to achieve the desired goals after participating in a specific, progressive, adequate

    We reviewed the pre- and postoperative lateral cervical roentgenograms in 90 patients who had anterior fusions and compared their findings with age and sex-matched people without neck problems. The average interval from surgery to review was 5 years. Preoperatively, all patients had a higher incidence of degenerative spondylosis at the levels to be fused than their asymptomatic counterparts. Postoperatively, there was no difference in the incidence of degenerative change between the operated and the control group at the levels above and below the fusion with the exception of anterior osteophyte formation which was more frequent in those with fusions.

    Full Text Available Congenital anterior tibiofemoral subluxation is an extremely rare disorder. All reported cases accompanied by other abnormalities and syndromes. A 16-year-old high school girl referred to us with bilateral anterior tibiofemoral subluxation as the knees were extended and reduced at more than 30 degrees flexion. Deformities were due to tightness of the iliotibial band and biceps femuris muscles and corrected by surgical release. Associated disorders included bilateral anterior shoulders dislocation, short metacarpals and metatarsals, and right calcaneuvalgus deformity.

    Surgeons often choose between 2 different approaches (anterior and posterior) for surgical treatment of degenerative cervical myelopathy on the basis of imaging features of spinal cord compression, the number of levels affected, and the spinal alignment. However, there is a lack of consensus on which approach is preferable. The objective of the present study was to use magnetic resonance imaging (MRI)-based propensity-score-matched analysis to compare postoperative outcomes between the anterior and posterior surgical approaches for degenerative cervical myelopathy. A total of 757 patients were enrolled in 2 prospective multicenter AOSpine studies, which involved 26 international sites. Preoperative MRIs were reviewed to characterize the causes of the cord compression, including single-level disc disease, multilevel disc disease, ossification of the posterior longitudinal ligament, enlargement of the ligamentum flavum, vertebral subluxation/spondylolisthesis, congenital fusion, number of compressed levels, or kyphosis. The propensity to choose anterior decompression was calculated using demographic data, preoperative MRI findings, and the modified Japanese Orthopaedic Association (mJOA) scores in a logistic regression model. We then performed 1-to-1 matching of patients who had received anterior decompression with those who had the same propensity score but had received posterior decompression to compare 2-year postoperative outcomes and 30-day perioperative complication rates between the 2 groups after adjustment for background characteristics. A total of 435 cases were included in the propensity score calculation, and 1-to-1 matching resulted in 80 pairs of anterior and posterior surgical cases; 99% of these matched patients had multilevel compression. The anterior and posterior groups did not differ significantly in terms of the postoperative mJOA score (15.1 versus 15.3, p = 0.53), Neck Disability Index (20.5 versus 24.1, p = 0.44), or Short Form-36 (SF-36

    Endoscopic sinonasal surgery is the procedure of choice in the treatment of chronic rhinosinusitis and sinonasal polyposis refractory to medical treatment, with high rates of success (76% to 97.5%). However, 2.5%-24% of those patients will require revision surgery (RESS). In this study, we present the clinical, anatomical, radiological and histological features of patients receiving RESS in our centre during a 3-year period. A retrospective review of clinical, anatomical, radiological and histopathological data of patients receiving revision endoscopic sinonasal surgery between 2012 and 2014 was carried out. From 299 surgery procedures performed, 27 (9%) were revision surgeries. The mean patient age was 46 years, with a male/female ratio of 1.4/1. The most frequent preoperative and postoperative diagnosis was chronic polypoid rhinosinusitis. The mean time since the previous surgery was 6.1 years, with 11.9 months of mean follow-up since that surgery. Stenotic antrostomy was found during revision in 81.5% of the patients and incomplete anterior ethmoidectomy and persistent uncinate process, in 59.3%. In radiology, 70.4% of patients had persistent anterior ethmoidal cells. Antrostomy or widening of antrostomy was performed in 96.3% of cases and anterior ethmoidectomy or completion of it was performed in 66.7%. Polyps, stenotic antrostomy and incomplete ethmoidectomy were the most frequent causes of revision surgery, in concordance with the procedures performed. The patients had long periods of time without follow-up between surgeries. Further investigation is necessary to generate measures to reduce the number of revision surgeries.

    The anterior ethmoidal artery (AEA) is an important point for frontal and ethmoid sinuses surgery. CT scans can identify landmarks to help the surgeon find the AEA. To identify the landmarks of the AEA on the orbital medial wall and on the lateral wall of the olfactory fossa. and to correlate the presence of supraorbital ethmoidal cells with spotting the anterior ethmoidal artery canal. Retrospective review of 198 direct coronal paranasal sinuses computed tomography (CT) scans from August to December, 2006. Supraorbital pneumatization was seen in 35% (70 scans). The AEA canal was seen in 41% (81 scans). The anterior ethmoidal sulcus was seen in 98% (194 scans) and the anterior ethmoidal foramen was seen in all the scans (100%). The anterior ethmoidal foramen and the anterior ethmoidal sulcus were anatomical landmarks present in almost 100% of the scans studied. There was a correlation between the presence of supraorbital pneumatization and AEA canal visualization.

    Post traumatic anterior abdominal wall hernia can be ignored in emergency settings. We here report the case of a 32-year-old patient with a BMI of 30 kg/m 2 , suffering from anterior abdominal wall hernia as a result of a road accident. This lesion wasn't detected during clinical examination. Abdominal tomodensitometry showed a defect of 8 cm in the anterior abdominal wall. The patient underwent surgery during which a musculoaponeurotic defect of 12 cm was detected. The repair was carried out using interrupted suture. The postoperative course was marked by a secondarily infected skin necrosis. The evolution was satisfactory after directed cicatrization. At 3 months postoperatively the patient was doing well with a healed wound and a strong abdominal wall.

    Anterior cervical fusion has become a standard of care for numerous pathologic conditions of the cervical spine. However, subsequent development of clinically significant disc disease at levels adjacent to fused discs is a serious long-term complication of this procedure. As more patients live longer after surgery, it is foreseeable that adjacent segment pathology (ASP) will develop in increasing numbers of patients. Also, ASP has been studied more intensively with the recent popularity of mo...

    Full Text Available Purpose. Ischemic ocular disorders may be treated by hypervolemic hemodilution. The presumed therapeutic benefit is based on a volume effect and improved rheological factors. The aim was to investigate the acute effect of intravenous hydroxyethyl starch on retrobulbar hemodynamics in patients with nonarteritic anterior ischemic optic neuropathy (NAION. Methods. 24 patients with acute NAION were included. Retrobulbar hemodynamics were measured using color Doppler imaging before and 15 min after intravenous infusion of 250 cc 10% hydroxyethyl starch (HES. Peak systolic velocity (PSV, end diastolic velocity (EDV, and Pourcelot’s resistive index (RI were measured in the ophthalmic artery (OA, central retinal artery (CRA, and short posterior ciliary arteries (PCAs. Results. After infusion of HES blood flow velocities significantly increased in the CRA (PSV from 7.53±2.33 to 8.32±2.51  (p<0.001; EDV from 2.16±0.56 to 2.34±0.55  (p<0.05 and in the PCAs (PSV from 7.18±1.62 to 7.56±1.55  (p<0.01; EDV from 2.48±0.55 to 2.66±0.6 cm/sec (p<0.01. The RI of all retrobulbar vessels remained unaffected. Blood pressure and heart rate remained unchanged. Conclusions. Hypervolemic hemodilution has an acute effect on blood flow velocities in the CRA and PCAs in NAION patients. Increased blood flow in the arteries supplying the optic nerve head may lead to a better perfusion in NAION patients. This trial is registered with DRKS00012603.

    Full Text Available Controversy surrounds the remnant-preserving anterior cruciate ligament surgery. Advantages of remnant preservation have been reported in regard to better healing and knee function, although no consensus has been reached. This review article discussed the value and meaning of anterior cruciate ligament remnant preservation in several sections such as effects on healing, remnant classification, biomechanical evaluation, relation to proprioception, animal studies, and clinical studies. We hope that this review will facilitate further discussion and investigation for better treatment of anterior cruciate ligament injuries. So far, the current reviews have not provided sufficient scientific evidence to support the value of preserving the remnant.

  4. Anterior open bite: aetiology and management.

    Science.gov (United States)

    Sandler, Paul Jonathan; Madahar, Arun K; Murray, Alison

    2011-10-01

    Anterior open bite has a multi-factorial aetiology comprising: genetically inherited skeletal pattern, soft tissue effect and digit-sucking habits. To formulate an appropriate treatment plan, accurate diagnosis is essential. Simple open bites may sometimes resolve completely during the transition from mixed to permanent dentition, if the digit-sucking habit is broken. More significant open bites, however, sometimes extending right back to the terminal molars, rarely resolve spontaneously and will often require complex orthodontic treatment, involving active molar intrusion or even major orthognathic surgery. Unfortunately, surgery has associated risks attached, including pain, swelling, bruising, altered nerve sensation and, occasionally, permanent anaesthesia, as well as involving significant costs, as with any major surgical procedure under general anaesthesia. The introduction of Temporary Anchorage Devices (TADs) has expanded the possibilities of orthodontic treatment, beyond traditional limitations of tooth movement. Molar intrusion can be successfully carried out without the need for major surgical intervention, thus avoiding all the attendant risks and disadvantages. This paper provides an overview of anterior open bite and uses an illustrative case where open bite was successfully treated with a combination of fixed appliance therapy and TADs. Anterior open bite is commonly seen in general practice. A knowledge of the possible aetiological factors and their potential management should be understood by general dental practitioners. The increased popularity of TADS allows a new and less invasive approach to management of these cases.

    The purpose of this present study was to examine contralateral ACL injury cases after ACL reconstruction, to determine the characteristics of such injuries. We performed a retrospective analysis of 24 patients with contralateral ACL injury after ACL reconstruction. The control group consisted of 200 cases with unilateral ACL injury. The following were examined in the contralateral group: timing of the contralateral ACL injury, and the situations of the initial and contralateral ACL injuries. The following items were compared between the contralateral and control groups: age at the time of initial injury, level of competitive sports using Tegner activity scores, knee anterior laxity (KT-1000), and the ratio (%) of affected to unaffected legs in the strengths of the knee extensor and flexor muscles 6 months after surgery. Examination of injury situations showed that approximately 70% of the contralateral group was injured in situations similar to those at their initial injuries. There were no significant differences between the two groups in age at the time of initial injury , Tegner activity scores, knee anterior laxity, and the strengths of the knee extensor, flexor muscles and H/Q ratio 6 months after reconstruction. But, the age at the time of initial injury trended to be low in contralateral group. Knee anterior laxity and muscle weakness of the reconstructed legs six months following surgery were not individually related to contralateral ACL injury occurring approximately two years after surgery.

    Tearing of the anterior capsule of the shoulder is a rare but debilitating injury for throwing athletes. However, there is very little in the literature to guide its diagnosis and treatment. In this case series, we outline our experience with anterior capsular tears of the shoulder in professional baseball players. Five professional baseball players were diagnosed with midsubstance tears of their anterior capsule. A trial of rest and rehabilitation failed in all patients, and they eventually underwent surgery. These patients were retrospectively reviewed. The presenting symptoms and findings were documented, and outcomes were assessed by the player's ability to return to play. The mean age was 33.5 years (range, 31-37 years), and all patients presented with anterior shoulder pain and the inability to throw. No patient had an acute traumatic injury. Magnetic resonance imaging provided the correct diagnosis in 4 patients, and the diagnosis was made with diagnostic arthroscopy in the fifth. Three underwent arthroscopic repair, and 2 underwent open repair of the anterior capsule. Of the 5 players, 4 (80%) returned to their preinjury level by a mean of 13.3 months (range, 8-18 months). Anterior capsular tears can occur in older throwing athletes. Surgical repair, whether arthroscopic or open, can yield good results in most patients.

    The present review classifies and describes the multifactorial causes of anterior cruciate ligament (ACL) surgery failure, concentrating on preventing and resolving such situations. The article particularly focuses on those causes that require ACL revision due to recurrent instability, without neglecting those that affect function or produce persistent pain. Although primary ACL reconstruction has satisfactory outcome rates as high as 97%, it is important to identify the causes of failure, because satisfactory outcomes in revision surgery can drop to as much as 76%. It is often possible to identify a primary or secondary cause of ACL surgery failure; even the most meticulous planning can give rise to unexpected findings during the intervention. The adopted protocol should therefore be sufficiently flexible to adapt to the course of surgery. Preoperative patient counseling is essential. The surgeon should limit the patient’s expectations for the outcome by explaining the complexity of this kind of procedure. With adequate preoperative planning, close attention to details and realistic patient expectations, ACL revision surgery may offer beneficial and satisfactory results for the patient. PMID:26550585

Five of these patients developed TASS postoperatively.Results: Patients had blurred-vision complaints on the first day after the operation, but no pain. They had different degrees of diffuse corneal edema, anterior-chamber reaction, fibrin, hypopyon, iris atrophies, and dilated pupils. Their vision decreased significantly, and their intraocular pressures increased. Both anti-inflammatory and antiglaucomatous therapies were commenced. Corneal edema and inflammation resolved in three cases; however, penetrating keratoplasty was needed for two cases and additional trabeculectomy was needed for one case. Although full investigations were undertaken at all steps, we could not find the causative agent.Conclusion: TASS is a preventable complication of anterior-segment surgery. Recognition of TASS, differentiating it from endophthalmitis, and starting treatment immediately is important. Controlling all steps in surgery, cleaning and sterilization of the instruments, and training nurses and other operation teams will help us in the prevention of TASS.

    Full Text Available A 46-year-old male patient was referred to our clinic with complaints of diplopia and esotropia in his right eye that developed after a car accident. The patient had right esotropia in primary position and abduction of the right eye was totally limited. Primary deviation was over 40 prism diopters at near and distance. The patient was diagnosed with sixth nerve palsy and 18 months after trauma, he underwent right medial rectus muscle recession. Ten months after the first operation, full-thickness tendon transposition of the superior and inferior rectus muscles (with Foster suture was performed. On the first postoperative day, slit-lamp examination revealed corneal edema, 3+ cells in the anterior chamber and an irregular pupil. According to these findings, the diagnosis was anterior segment ischemia. Treatment with 0.1/5 mL topical dexamethasone drops (16 times/day, cyclopentolate hydrochloride drops (3 times/day and 20 mg oral fluocortolone (3 times/day was initiated. After 1 week of treatment, corneal edema regressed and the anterior chamber was clean. Topical and systemic steroid treatment was gradually discontinued. At postoperative 1 month, the patient was orthophoric and there were no pathologic symptoms besides the irregular pupil. Anterior segment ischemia is one of the most serious complications of strabismus surgery. Despite the fact that in most cases the only remaining sequel is an irregular pupil, serious circulation deficits could lead to phthisis bulbi. Clinical properties of anterior segment ischemia should be well recognized and in especially risky cases, preventative measures should be taken.

    Patients irradiated for left-sided breast cancer have higher incidence of cardiovascular disease than those receiving irradiation for right-sided breast cancer. Most abnormalities were in the left anterior descending (LAD) coronary artery territory. We analyzed the relationships between preoperative examination results and irradiation dose to the LAD artery in patients with left-sided breast cancer. Seventy-one patients receiving breast radiotherapy were analyzed. The heart may rotate around longitudinal axis, showing either clockwise or counterclockwise rotation (CCWR). On electrocardiography, the transition zone (TZ) was judged in precordial leads. CCWR was considered to be present if TZ was at or to the right of V3. The prescribed dose was 50 Gy in 25 fractions. The maximum (Dmax) and mean (Dmean) doses to the LAD artery and the volumes of the LAD artery receiving at least 20 Gy, 30 Gy and 40 Gy (V20Gy, V30Gy and V40Gy, respectively) were significantly higher in CCWR than in the non-CCWR patients. On multivariate analysis, TZ was significantly associated with Dmax, Dmean, V20Gy, V30Gy, and V40Gy. CCWR is a risk factor for high-dose irradiation to the LAD artery. Electrocardiography is useful for evaluating the cardiovascular risk of high-dose irradiation to the LAD artery.

    The accuracy of the anterior drawer test for the diagnosis of recent lateral ligament tears in the ankle was evaluated in a series of 192 patients using surgical or arthrographic findings for reference. Considerable overlapping of results was obtained in ankles with and without ligament tear. Twenty-eight per cent of the anterior talofibular ligament tears, and 38% of the combined anterior talofibular and calcaneofibular tears were not detected, and single and combined tears could not be differentiated. It is concluded that the anterior drawer test is too unreliable as a basis for any decision regarding surgical treatment of a recent sprain. Therefore, arthrography is recommended as the method of choice in such cases of recent ankle sprain, where the need of surgery has to be supported by X-ray analysis.

    Full Text Available We studied the clinical presentation and management of four patients with anterior urethral valves; a rare cause of urethral obstruction in male children. One patient presented antenatally with oligohydramnios, bilateral hydronephrosis and bladder thickening suggestive of an infravesical obstruction. Two other patients presented postnatally at 1 and 2 years of age, respectively, with poor stream of urine since birth. The fourth patient presented at 9 years with frequency and dysuria. Diagnosis was established on either micturating cystourethrogram (MCU (in 2 or on cystoscopy (in 2. All patients had cystoscopic ablation of the valves. One patient developed a postablation stricture that was resected with an end-to-end urethroplasty. He had an associated bilateral vesicoureteric junction (VUJ obstruction for which a bilateral ureteric reimplantation was done at the same time. On long-term follow-up, all patients demonstrated a good stream of urine. The renal function is normal. Patients are continent and free of urinary infections. Anterior urethral valves are rare obstructive lesions in male children. The degree of obstruction is variable, and so they may present with mild micturition difficulty or severe obstruction with hydroureteronephrosis and renal impairment. Hence, it is important to evaluate the anterior urethra in any male child with suspected infravesical obstruction. The diagnosis is established by MCU or cystoscopy and the treatment is always surgical, either a transurethral ablation or an open resection. The long-term prognosis is good.

    To evaluate the serial changes in anterior chamber depth (ACD) and angle parameters early after cataract surgery using anterior segment optical coherence tomography (ASOCT). This was a retrospective chart review, case-control study; 150 eyes of 106 patients who underwent cataract surgery. Based on ACD and angle findings, the eyes were classified into two groups, open-angle eyes (87 eyes) and narrow-angle eyes (63 eyes). ASOCT was used to measure ACD and angle parameters (angle opening distance, angle recess area, trabecular iris space area, and trabecular iris angle (TIA [1]). Serial changes in each group were measured before and 1 day, 1 week, and 1 month after cataract surgery, and the differences between the two groups were compared. ACD and all angle parameters in both groups at each examination time after cataract surgery were significantly different from the preoperative values (p < 0.01). In addition, all angle parameters significantly differed between the two groups at each examination time after cataract surgery (p < 0.001). However, ACD after surgery was not significantly different, irrespective of ACD before surgery. ACD and TIA500 both showed significantly greater changes from before surgery to 1 day after surgery in narrow-angle eyes compared to open-angle eyes (p < 0.001). Cataract surgery increases ACD and all angle parameters early after the surgery. However, the degree of angle widening in narrow-angle eyes was not as much as that in open-angle eyes, suggesting that factors other than the lens influence the angle closure.

    Pseudoaneurysmal epistaxis is a rare but emergent condition. We report a case of traumatic anterior cerebral artery pseudoaneurysmal epistaxis and review the published literature. A 49-year-old man sustained severe head trauma. He was diagnosed with multiple skull bone fractures, left subdural hematoma, subarachnoid hemorrhage, pneumocephalus, and right frontal hematoma. Subdural hematoma evacuation was done at a local hospital. In the following months, he experienced repeated epistaxis that required nasal packing to stop the bleeding. Digital subtraction angiography showed an anterior cerebral artery pseudoaneurysm protruding into the posterior ethmoid sinus. Embolization of the aneurysm was performed with microcoils, and the parent artery was occluded by thrombosis. The patient presented 1 month later with another epistaxis episode. Digital subtraction angiography showed recanalization of the parent artery and recurrence of the aneurysm. The parent artery was occluded for the second time with coils and Onyx embolic agent. Pseudoaneurysmal epistaxis is rare, and this is the first report of an anterior cerebral artery pseudoaneurysm that manifested with epistaxis. Endovascular intervention has become the first choice of treatment for this disease. The high recurrence rate is the main disadvantage of endovascular intervention. Aneurysm trapping with bypass surgery is another treatment option. Copyright © 2016 Elsevier Inc. All rights reserved.

    Anterior knee pain is a common complain in all ages athletes. It may be caused by a large variety of injuries. There is a continuum of diagnoses and most of the disorders are closely related. Repeated minor trauma and overuse play an important role for the development of lesions in Hoffa's pad, extensor mechanism, lateral and medial restrain structures or cartilage surface, however usually an increase or change of activity is referred. Although the direct relation of cartilage lesions, especially chondral, and pain is a subject of debate these lesions may be responsible of early osteoarthrosis and can determine athlete's prognosis. The anatomy and biomechanics of patellofemoral joint is complex and symptoms are often unspecific. Transient patellar dislocation has MR distinct features that provide evidence of prior dislocation and rules our complication. However, anterior knee pain more often is related to overuse and repeated minor trauma. Patella and quadriceps tendon have been also implicated in anterior knee pain, as well as lateral or medial restraint structures and Hoffa's pad. US and MR are excellent tools for the diagnosis of superficial tendons, the advantage of MR is that permits to rule out other sources of intraarticular derangements. Due to the complex anatomy and biomechanic of patellofemoral joint maltracking is not fully understood; plain films and CT allow the study of malalignment, new CT and MR kinematic studies have promising results but further studies are needed. Our purpose here is to describe how imaging techniques can be helpful in precisely defining the origin of the patient's complaint and thus improve understanding and management of these injuries.

    Anterior cervical fusion has become a standard of care for numerous pathologic conditions of the cervical spine. However, subsequent development of clinically significant disc disease at levels adjacent to fused discs is a serious long-term complication of this procedure. As more patients live longer after surgery, it is foreseeable that adjacent segment pathology (ASP) will develop in increasing numbers of patients. Also, ASP has been studied more intensively with the recent popularity of motion preservation technologies like total disc arthroplasty. The true nature and scope of ASP remains poorly understood. The etiology of ASP is most likely multifactorial. Various factors including altered biomechanical stresses, surgical disruption of soft tissue and the natural history of cervical disc disease contribute to the development of ASP. General factors associated with disc degeneration including gender, age, smoking and sports may play a role in the development of ASP. Postoperative sagittal alignment and type of surgery are also considered potential causes of ASP. Therefore, a spine surgeon must be particularly careful to avoid unnecessary disruption of the musculoligamentous structures, reduced risk of direct injury to the disc during dissection and maintain a safe margin between the plate edge and adjacent vertebrae during anterior cervical fusion.

    Full Text Available The anterior cingulate cortex (ACC has a role in attention, analysis of sensory information, error recognition, problem solving, detection of novelty, behavior, emotions, social relations, cognitive control, and regulation of visceral functions. This area is active whenever the individual feels some emotions, solves a problem, or analyzes the pros and cons of an action (if it is a right decision. Analogous areas are also found in higher mammals, especially whales, and they contain spindle neurons that enable complex social interactions. Disturbance of ACC activity is found in dementias, schizophrenia, depression, the obsessive-compulsive syndrome, and other neuropsychiatric diseases.

All of these patients were treated with vitrectomy and partial capsulectomy via anterior approach.RESULTS:Six of 9 patients were male. The average patients’ age was (60±8.1 years. The average period between cataract extraction and onset of signs and symptoms was (3.6±1.3 weeks. The average presenting visual acuity was 0.3±0.1 and the average final post operative visual acuity was 0.7±0.2. The mean follow-up period was (28.1±8.9 weeks. In all patients, the inflammation subsided after surgery.CONCLUSION:Our results suggest that anterior vitrectomy and partial capsulectomy via anterior approach may be considered as potentially useful and relatively less invasive technique to treat CPE.

  18. Late spontaneous resolution of a double anterior chamber post deep anterior lamellar keratoplasty

    Full Text Available A 31-year-old healthy male underwent deep anterior lamellar keratoplasty with big-bubble technique for treatment of keratoconus in his right eye. One week after surgery, he presented with detachment of the endothelium-Descemet complex with formation of a double anterior chamber, despite the apparent absence of an intraoperative Descemet membrane rupture. A subsequent intervention with the intent to relocate the corneal graft button was not effective, because the detachment appeared again one day later. The authors hypothesized that, at the time of the stromal dissection with big bubble technique, a small amount of air penetrated into the anterior chamber, creating a false pathway through the trabecular meshwork. The aqueous humor then penetrated the graft flowing through the false pathway, causing the endothelium-Descemet detachment. The persistence of that pathway, even after the intervention of graft repositioning, caused the failure of the latter procedure and persistence of the double chamber. We decided to wait and observe. The double anterior chamber spontaneously resolved in approximately three months.

    Full Text Available Guy SalletDepartment of Opthamology, Aalsters Stedelijk Ziekenhuis, BelgiumAbstract: A cataract surgery technique is described in which incisions, continuous circular capsulorhexis and hydrodissection are made without the use of any viscoelastics. Two small incisions are created through which the different parts of the procedure can take place, maintaining a stable anterior chamber under continuous irrigation. Subsequent bimanual phacoemulsification can be done through these microincisions. At the end of the procedure, an intraocular lens can be inserted through the self-sealing incision under continuous irrigation. 50 consecutive cataract patients were operated on without the use of viscoelastics and then compared with a group of 50 patients who had been helped with viscoelastics. No difference in outcome, endothelial cell count or pachymetry was noted between the two groups. No intraoperative complication was encountered. Viscoless cataract surgery was a safe procedure with potential advantages.Keywords: ophthalmic visco-surgical device, viscoless cataract surgery, microincision

  20. Early versus delayed reconstruction of the anterior cruciate ligament: a decision analysis approach.

    Science.gov (United States)

    Bernstein, Joseph

    2011-05-04

    A recent randomized controlled trial compared early anterior cruciate ligament reconstruction with a program of initial rehabilitation, with delayed anterior cruciate ligament reconstruction if needed. The authors reported that the improvement in Knee Injury and Osteoarthritis Outcome Scores was nearly identical in both groups and concluded that in young, active adults with acute ACL (anterior cruciate ligament) tears, a strategy of rehabilitation plus early ACL reconstruction was not superior to a strategy of rehabilitation plus optional delayed ACL reconstruction. Yet, in making that assessment, the authors did not account for the fact that there were more meniscal injuries in the group with delayed anterior cruciate ligament surgery. Establishing the true superiority of one strategy requires consideration of meniscal injury, as well as a further determination if the apparent protective effect regarding meniscal tears found in the cohort of patients with early anterior cruciate ligament reconstruction is offset by the costs of additional reconstructive surgery. That analysis of offsetting utility, omitted in the randomized controlled trial noted above, is provided in the present study. A decision analysis model considering the options and probabilities described in the randomized controlled trial was constructed: the functional outcome of all groups was assumed to be equal, the likelihood of a patient eventually needing surgery despite initially choosing a program of rehabilitation was 37%, and the likelihood of needing a meniscectomy was 23% for the early surgery group and 35% for the rehabilitation and deferred anterior cruciate ligament reconstruction group. The early surgery option is the preferable therapeutic approach as long as the costs of a potential meniscal tear are at least 5.25 times the costs of reconstructive surgery. Early surgery for anterior cruciate ligament tears may be the preferred approach for some patients, on the basis of the utility

    Although the anterior guidance in complete dentures is not really a guide, the arrangement of the anterior maxillary and mandibular prosthetic teeth, defines a propulsive line called the virtual anterior guidance, a part from the cinematic criterias. The influence of this guide on cuspal movement is superior, in all mandibular points, to the influence of the condylar pathway. If this line is not respected, the practitioner may have to do excessive grindings during occlusal adjustments.

    The present invention provides a method for producing an anterior cruciate ligament ex vivo. The method comprises seeding pluripotent stem cells in a three dimensional matrix, anchoring the seeded matrix by attachment to two anchors, and culturing the cells within the matrix under conditions appropriate for cell growth and regeneration, while subjecting the matrix to one or more mechanical forces via movement of one or both of the attached anchors. Bone marrow stromal cells are preferably used as the pluripotent cells in the method. Suitable matrix materials are materials to which cells can adhere, such as a gel made from collagen type I. Suitable anchor materials are materials to which the matrix can attach, such as Goinopra coral and also demineralized bone. Optimally, the mechanical forces to which the matrix is subjected mimic mechanical stimuli experienced by an anterior cruciate ligament in vivo. This is accomplished by delivering the appropriate combination of tension, compression, torsion, and shear, to the matrix. The bioengineered ligament which is produced by this method is characterized by a cellular orientation and/or matrix crimp pattern in the direction of the applied mechanical forces, and also by the production of collagen type I, collagen type III, and fibronectin proteins along the axis of mechanical load produced by the mechanical forces. Optimally, the ligament produced has fiber bundles which are arranged into a helical organization. The method for producing an anterior cruciate ligament can be adapted to produce a wide range of tissue types ex vivo by adapting the anchor size and attachment sites to reflect the size of the specific type of tissue to be produced, and also adapting the specific combination of forces applied, to mimic the mechanical stimuli experienced in vivo by the specific type of tissue to be produced. The methods of the present invention can be further modified to incorporate other stimuli experienced in vivo by the

  11. The anterior interhemispheric approach: a safe and effective approach to anterior skull base lesions.

    Many approaches to the anterior skull base have been reported. Frequently used are the pterional, the unilateral or bilateral frontobasal, the supraorbital and the frontolateral approach. Recently, endoscopic transnasal approaches have become more popular. The benefits of each approach has to be weighted against its complications and limitations. The aim of this study was to investigate if the anterior interhemispheric approach (AIA) could be a safe and effective alternative approach to tumorous and non-tumorous lesions of the anterior skull base. We screened the operative records of all patients with an anterior skull base lesion undergoing transcranial surgery. We have used the AIA in 61 patients. These were exclusively patients with either olfactory groove meningioma (OGM) (n = 43), ethmoidal dural arteriovenous fistula (dAVF) ( n = 6) or frontobasal fractures of the anterior midline with cerebrospinal fluid (CSF) leakage ( n = 12). Patient records were evaluated concerning accessibility of the lesion, realization of surgical aims (complete tumor removal, dAVF obliteration, closure of the dural tear), and approach related complications. The use of the AIA exclusively in OGMs, ethmoidal dAVFs and midline frontobasal fractures indicated that we considered lateralized frontobasal lesions not suitable to be treated successfully. If restricted to these three pathologies, the AIA is highly effective and safe. The surgical aim (complete tumor removal, complete dAVF occlusion, no rhinorrhea) was achieved in all patients. The complication rate was 11.5 % (wound infection (n = 2; 3.2 %), contusion of the genu of the corpus callosum, subdural hygroma, epileptic seizure, anosmia and asymptomatic bleed into the tumor cavity (n = 1 each). Only the contusion of the corpus callosum was directly related to the approach (1.6 %). Olfaction, if present before surgery, was preserved in all patients, except one (1.6 %). The AIA is an effective and a safe approach

    2011-01-01

    No study reports the histological features of the various zone of the anterior tubercle of the tibia in the different stages of the Osgood-Schlatter (O-S) lesion. For this reason we carried on an histological study. Specimens were taken from 13 patients with O-S lesion prior to surgery. In 4 cases in the apophyseal stage lesions were present in an altered fibrocartilage anterior to the ossification centre. In 9 cases in the epiphyseal stage varying degrees of reparative tissues were observed in the bed of the fragment of the secondary ossification centre. In 3 of them a zone of lesion was observed within the fibrocartilage anterior to the ossification centre. These results suggest that the slippage of the patellar tendon insertion may be progressive and caused by pathological fibrocartilage.

    2016-09-01

    To measure and compare the amount of anterior tibial subluxation (ATS) after anatomic ACL reconstruction for both acute and chronic ACL-deficient patients. Fifty-two patients were clinically and radiographically evaluated after primary, unilateral, anatomic ACL reconstruction. Post-operative true lateral radiographs were obtained of both knees with the patient in supine position and knees in full passive extension with heels on a standardized bolster. ATS was measured on the radiographs by two independent and blinded observers. ATS was calculated as the side-to-side difference in tibial position relative to the femur. An independent t test was used to compare ATS between those undergoing anatomic reconstruction for an acute versus chronic ACL injury. Chronic ACL deficiency was defined as more than 12 weeks from injury to surgery. Patients averaged 26.4 ± 11.5 years (mean ± SD) of age, 43.6 % were female, and 48.1 % suffered an injury of the left knee. There were 30 and 22 patients in the acute and chronic groups, respectively. The median duration from injury to reconstruction for the acute group was 5 versus 31 weeks for the chronic group. After anatomic ACL reconstruction, the mean ATS was 1.0 ± 2.1 mm. There was no statistical difference in ATS between the acute and chronic groups (1.2 ± 2.0 vs. 0.6 ± 2.3 mm, n.s.). Assessment of inter-tester reliability for radiographic evaluation of ATS revealed an excellent intraclass correlation coefficient of 0.894. Anatomic ACL reconstruction reduces ATS with a mean difference of 1.0 mm from the healthy contralateral limb. This study did not find a statistical difference in ATS between patients after anatomic ACL reconstruction in the acute or chronic phase. These observations suggest that anatomic ACL reconstruction, performed in either the acute or the chronic phase, approaches the normal AP relationship of the tibiofemoral joint. IV.

    Temporomandibular joint (TMJ) disorders are a common disease and may be responsible for major functional and painful repercussions. Treatment is not consensual. The literature highlights the role of conservative treatments (physiotherapy, analgesics, splints) in a first attempt. Minimally invasive surgical techniques (arthroscopy, arthrocentesis) have developed rapidly in recent decades. They have proven effective and reliable, especially in patients suffering from irreducible or reducible anterior disc dislocation or presenting with arthopathies. The goal of our work was to make an update about disk surgery. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Full Text Available Objective To study the clinical manifestations, pathologic features, diagnosis, treatment and prognosis of primary synovial sarcoma in the anterior mediastinum. Methods A case of primary synovial sarcoma in the anterior mediastinum was reported. Clinical features, imaging manifestations, pathology features and therapeutic effect were analysed and the relevant literature was reviewed. Results A 48-year-male patient was admitted with complaint of right chest pain for 4 days. Chest computerized tomography revealed a large mass located at the right anterior mediastinum, and it was primarily diagnosed as invasive thymoma. Pathological examination by CT-guided percutaneous needle biopsy manifested that, under microscope, the tumor cells were short and spindle in shape forming a nest structure, suggested it was a thymoma. The patient then underwent resection of thymoma with removal of fat and connective tissue in the anterior mediastinum. During the operation the size of the tumor was 15cm×15cm×10cm, being located at the anterior mediastinum, and it tended to bleed. The diagnosis of primary monophasic synovial sarcoma in the mediastinum was confirmed by postoperative/pathology examination. Immunohistochemistry staining showed that the tumor cells were positive for the markers Bcl-2 and EMA, but negative for the markers CK (pan and S100. The patient suffered from local recurrence with metastases to lung 4 months after surgery. The patient received 2 chemotherapeutic courses with ifosfamide, epirubicin and cisplatin. He died 6 months after surgery. Conclusion Primary synovial sarcoma in the anterior mediastinum is an extremely rare and highly malignant tumor with poor prognosis. The diagnosis depends on the pathological features, immunohistochemistry and RT-PCR. Radical resection combined with comprehensive treatment may improve the survival rate.

    The purpose of this study was to detect the anterior loop of the mental nerve and the mandibular incisive canal in panoramic radiographs (PAN) and cone-beam computed tomography (CBCT) images, as well as to determine the anterior/mesial extension of these structures in panoramic and cross-sectional reconstructions using PAN and CBCT images. Images (both PAN and CBCT) from 90 patients were evaluated by 2 independent observers. Detection of the anterior loop and the incisive canal were compared between PAN and CBCT. The anterior/mesial extension of these structures was compared between PAN and both cross-sectional and panoramic CBCT reconstructions. In CBCT, the anterior loop and the incisive canal were observed in 7.7% and 24.4% of the hemimandibles, respectively. In PAN, the anterior loop and the incisive canal were detected in 15% and 5.5% of cases, respectively. PAN presented more difficulties in the visualization of structures. The anterior/mesial extensions ranged from 0.0 mm to 19.0 mm on CBCT. PAN underestimated the measurements by approximately 2.0 mm. CBCT appears to be a more reliable imaging modality than PAN for preoperative workups of the anterior mandible. Individual variations in the anterior/mesial extensions of the anterior loop of the mental nerve and the mandibular incisive canal mean that is not prudent to rely on a general safe zone for implant placement or bone surgery in the interforaminal region.

    Ankle arthrodesis is a common procedure that resolves many conditions of the foot and ankle; however, complications following this procedure are often reported and vary depending on the fixation technique. Various techniques have been described in the attempt to achieve ankle arthrodesis and there is much debate as to the efficiency of each one. This study aims to evaluate the efficiency of anterior plating in ankle arthrodesis using customised and Synthes TomoFix plates. We present the outcomes of 28 ankle arthrodeses between 2005 and 2012, specifically examining rate of union, patient-reported outcomes scores, and complications. All 28 patients achieved radiographic union at an average of 36 wk; the majority of patients (92.86%) at or before 16 wk, the exceptions being two patients with Charcot joints who were noted to have bony union at a three year review. Patient-reported outcomes scores significantly increased (P plate offers added compression and provides a rigid fixation for arthrodesis stabilization. PMID:24649408

    Klinge, Stephen A; Sawyer, Gregory A; Hulstyn, Michael J

    2013-05-01

    Anterior cruciate ligament (ACL) rupture is a common knee injury and an understanding of current medical knowledge regarding its management is essential. Accurate and prompt diagnosis requires an awareness of injury mechanisms and risk factors, common symptoms and physical/radiologic findings. Early mobilization and physical therapy improves outcomes regardless of treatment modality. Many older patients regain sufficient stability and function after non-operative rehabilitation. Early ACL reconstruction is appropriate for younger patients and those who engage in activities requiring frequent pivoting and rapid direction changes. ACL surgery involves reconstruction of the torn ligament tissue with various replacement graft options, each with advantages and disadvantages. The guidance of a knowledgeable and experienced therapist is required throughout an intensive and prolonged rehabilitation course. Generally excellent outcomes and low complication rates are expected, but treatment does not prevent late osteoarthritis.

    2016-01-01

    Anterior cruciate ligament (ACL) reconstruction is one of the most common procedures in sports medicine. Several areas of controversy exist in ACL tear management which have engaged surgeons and researchers in debates towards identifying an ideal approach for these patients. This instructional review discusses the principles of ACL reconstruction in an attempt to provide guidelines and initiate a critical thinking approach on the most common areas of controversy regarding ACL reconstruction. Using high-level evidence from the literature, as presented in randomised controlled trials, systematic reviews, and meta-analyses, operative versus conservative treatment, timing of surgery, and rehabilitation are discussed. Also, the advantages and disadvantages of the most common types of autografts, such as patellar tendon and hamstrings as well as allografts are presented. Key considerations for the anatomical, histological, biomechanical and clinical data (‘IDEAL’) graft positioning are reviewed. Cite this article: Paschos NK, Howell SM.

    Spontaneous dislocation of intraocular lens with bag is rare. We report a case of a 56-year-old male who presented with spontaneous anterior dislocation of an in-the-bag intraocular lens 3 years after manual small incision cataract surgery. He had undergone manual small incision cataract surgery with foldable acrylic intraocular lens implantation, and 18 months after cataract surgery ND: YAG capsulotomy with uneventful post capsulotomy follow-up. 17 months after capsulotomy, the patient presented with sudden decrease of vision. On anterior segment examination, the intraocular lens with bag was dislocated into the anterior chamber. It was managed with intraocular lens explantation with bag, anterior vitrectomy and sclera fixated intraocular lens. Spontaneous intraocular lens dislocation with bag is possible after 1.5 years of uneventful surgery which may be managed using different techniques.

    To evaluate the pattern of anterior segment indocyanine green (ICG) angiography in episcleritis and scleritis. Prospective comparative (paired-eye) observational case series. Twenty subjects presenting clinical diseases compatible with episcleritis or scleritis. Anterior segment ICG angiography was performed according to a standard protocol in subjects presenting either episcleritis or scleritis. Photographs of the anterior segment were taken in the early phase (up to 3 minutes after dye injection), intermediate phase (10-12 minutes) and late phase (30-45 minutes). The inflamed zones were compared with the same regions of the controlateral eye. The amount of protein ICG exudation was scored by a masked observer as follows: zero for no exudation, one for slight exudation, two for moderate exudation, and three for severe exudation. Evaluation of dye leakage, which reflects protein exudation, with anterior segment ICG angiography in episcleritis and scleritis. Twenty subjects with a mean age of 43 +/- 15 years (7 male, 13 female) were enrolled in the study. Thirteen subjects had anterior scleritis (7 nodular, 5 diffuse, and 1 scleromalacia perforans), and 7 subjects had episcleritis. Only 1 out of 7 subjects with episcleritis showed a slight ICG leakage (a score of one), whereas all subjects with scleritis had ICG leakage scores of one or more (P = 0.0005, Fisher exact test). ICG angiography of the anterior segment of the eye is a good clinical test to differentiate episcleritis from scleritis.

    A retrospective clinical study was used to evaluate the effect of a new surgical treatment of the hangman's fractures. To determine the treatment efficacy of combined anterior C2-C3 reduction and fusion and posterior compressive C2 pedicle screw fixation for the management of unstable hangman's fractures. The classification of hangman's fractures as proposed by Levine-Edwards was used to classify and guide the treatment of these injuries. Most of these fractures respond to a variety of conservative therapies, but recently, earlier surgery has been increasingly advocated by authors from several countries for the rapid stabilization of these fractures. If surgery is indicated, an anterior approach using a C2-C3 reduction and fusion is preferred usually. Another well-accepted surgical method is the direct transpedicular osteosynthesis by the dorsal approach. However, there was rare report of the combined use of these 2 techniques. A group of 45 surgical patients were all diagnosed with radiograph, magnetic resonance imaging (MRI), and 3D CT scans. Initial and final radiographs were measured for anterior translation and angulation of the C2-C3 complex. Initial external skull traction with extension was used in all patients after admission to reduce the fracture. Then an anterior C2-C3 discectomy followed by an interbody fusion and locking plate fixation was performed. Intraoperative reduction was confirmed by fluoroscopic control. About 29 patients therefore received anterior surgeries only since satisfactory reduction was achieved during the procedure. For the 16 patients who had persistent large residual gaps after the anterior procedure, additional same stage posterior C2 compressive pedicle screws were placed. Clinical and radiologic comparisons were performed in these 2 groups. The follow-up ranged from 24 to 54 months, with an average 33.6 months. There was radiographic evidence of continuity of the fracture and the bone graft seen at 4.7 months on average. Neck

    Background: Anterior cervical discectomy is a common procedure for treating patients for cervical disc prolapse. This study was conducted to study the surgical outcome and demographic characteristics of patients who were treated for anterior cervical disc prolapse. Methods: Study was conducted in the combined military hospital (CMH) Peshawar. Study interval was 3 years from 1st September, 2011 to 31st August, 2014. Total number of patients were 84. Males were 54 (64.28 percentage) and females were 30 (35.71 percentage). All the patients had undergone the procedure of anterior cervical discectomy and fusion with titanium cages (ACDF). All the patients had plain MRI cervical spine done for diagnosis of anterior cervical disc prolapse. Results: Total 84 patients were operated. In the patients who complained of brachialgia, 100 percentage improvement was seen after the operation. Three (3.5 percentage) of the patients, who presented with axial neck pain, continued to complain of pain and 2 (2.5 percentage) of the patients complained of pain at the donor site after the operation. One of the patient had dural tear which resulted in subcutaneous cerebrospinal fluid (CSF) accumulation and was treated conservatively with repeated aspiration. Fusion rate was 100 percentage with titanium cages used for fusion after anterior cervical discectomy. No complications were noted after the surgery at 1 year of interval. Conclusion: Results with titanium cages are expectedly good. Symptoms resolved and fusion rate was 100 percentage at 1 year follow up. (author)

    was reflected in a need for more repeat operations for incontinence (25/107 (23%) versus 4/164 (2%); RR 8.87, 95% CI 3.28 to 23.94). These findings held, irrespective of the co-existence of prolapse (pelvic relaxation). Although fewer women had a prolapse after anterior repair (RR 0.24, 95% CI 0.12 to 0.47), later prolapse operation appeared to be equally common after vaginal (3%) or abdominal (4%) operation.In respect of the type of open abdominal retropubic suspension, most data related to comparisons of anterior vaginal repair with Burch colposuspension. The few data describing comparison of anterior repair with the Marshall-Marchetti-Krantz procedure were consistent with those for Burch colposuspension. There were not enough data to allow comparison of anterior vaginal repair with physical therapy or needle suspension for primary urinary stress incontinence in women. Open abdominal retropubic suspension appeared to be better than anterior vaginal repair judged on subjective cure rates in eight trials, even in women who had prolapse in addition to stress incontinence (six trials). The need for repeat incontinence surgery was also less after the abdominal operation. However, there was not enough information about postoperative complications and morbidity.A Brief Economic Commentary (BEC) identified one study suggesting that vaginoplasty may be more cost-effective compared with tension-free vaginal tape (TVT-O).

    Although the serratus anterior muscle has an important role in scapular movement, no study to date has investigated the effect of serratus anterior fatigue on scapular kinematics and shoulder muscle activity. The purpose of this study was to clarify the effect of serratus anterior fatigue on scapular movement and shoulder muscle activity. The study participants were 16 healthy men. Electrical muscle stimulation was used to fatigue the serratus anterior muscle. Shoulder muscle strength and endurance, scapular movement, and muscle activity were measured before and after the fatigue task. The muscle activity of the serratus anterior, upper and lower trapezius, anterior and middle deltoid, and infraspinatus muscles was recorded, and the median power frequency of these muscles was calculated to examine the degree of muscle fatigue. The muscle endurance and median power frequency of the serratus anterior muscle decreased after the fatigue tasks, whereas the muscle activities of the serratus anterior, upper trapezius, and infraspinatus muscles increased. External rotation of the scapula at the shoulder elevated position increased after the fatigue task. Selective serratus anterior fatigue due to electric muscle stimulation decreased the serratus anterior endurance at the flexed shoulder position. Furthermore, the muscle activities of the serratus anterior, upper trapezius, and infraspinatus increased and the scapular external rotation was greater after serratus anterior fatigue. These results suggest that the rotator cuff and scapular muscle compensated to avoid the increase in internal rotation of the scapula caused by the dysfunction of the serratus anterior muscle.

    Objective. To develop a new method of magnetic resonance arthrography (MRA) of the knee using an anterior approach analogous to the portals used for knee arthroscopy.Design. An anterior approach to the knee joint was devised mimicking anterior portals used for knee arthroscopy. Seven patients scheduled for routine knee MRA were placed in a decubitus position and under fluoroscopic guidance a needle was advanced from a position adjacent to the patellar tendon into the knee joint. After confirmation of the needle tip location, a dilute gadolinium solution was injected.Results and conclusion. All the arthrograms were technically successful. The anterior approach to knee MRA has greater technical ease than the traditional approach with little patient discomfort. (orig.)

    The diagnosis-related-groups (DRG) is the cost-based system for hospital reimbursement. However, the proceeds does not coincide with the costs. Aim of the study was to identify the profit, which we could gained with 147, 155, 158, 162, 165, 198 gastrointestinal surgery DRG. 30 consecutive patients, undergone to surgery in Clinica Chirurgica of L'Aquila University, had been studied. We had calculated the daily costs of medical and nursing practice, diagnostic tests, drugs, hospitalization, surgical instruments for every patient's therapy. The DRG-proceeds had been correlated with the DRG-costs. The "major gastrointestinal surgery" had not profit (147 DRG: anterior resection of rectum = -354428 Pounds, Miles = -94020 Pounds; 155 DRG: total gastrectomy = -1920641 Pounds). On the contrary, "minimal surgery" had good profits (158 DRG: hemorroidectomy with local anestesia = 1469605 Pounds;162 DRG: sutureless groin hernioplasty = 1561200 Pounds; 198 DRG: videolaparochole-cystectomy: 1208807 Pounds). The study seems to demonstrate the disparity of the reimbursement system related to DRG. However, the surgeons, as managers, must employ warily the resources for producing DRG.

  17. Systematic review of the surgery-first approach in orthognathic surgery

    2014-08-01

    Full Text Available The surgery-first approach in orthognathic surgery has recently created a broader interest in completely eliminating time-consuming preoperative orthodontic treatment. Available evidence on the surgery-first approach should be appraised to support its use in orthognathic surgery. A MEDLINE search using the keywords "surgery first" and "orthognathic surgery" was conducted to select studies using the surgery-first approach. We also manually searched the reference list of the selected keywords to include articles not selected by the MEDLINE search. The search identified 18 articles related to the surgery-first approach. There was no randomized controlled clinical trial. Four papers were excluded as the content was only personal opinion or basic scientific research. Three studies were retrospective cohort studies in nature. The other 11 studies were case reports. For skeletal Class III surgical correction, the final long-term outcomes for maxillofacial and dental relationship were not significantly different between the surgery-first approach and the orthodontics-first approach in transverse (e.g., intercanine or intermolar width dimension, vertical (e.g., anterior open bite, lower anterior facial height dimension, and sagittal (e.g., anterior-posterior position of pogonion and lower incisors dimension. Total treatment duration was substantially shorter in cases of surgery-first approach use. In conclusion, most published studies related to the surgery-first approach were mainly on orthognathic correction of skeletal Class III malocclusion. Both the surgery-first approach and orthodontics-first approach had similar long-term outcomes in dentofacial relationship. However, the surgery-first approach had shorter treatment time.

    Simple decompression and anterior subcutaneous transposition are effective surgical interventions for cubital tunnel syndrome and yield similarly favorable outcomes. However, a substantial proportion of patients demonstrate unsatisfactory outcomes for reasons that remain unclear. We compared effects of decompression and transposition on regional ulnar nerve strain to better understand the biomechanical impacts of each strategy. Patients diagnosed with cubital tunnel syndrome and scheduled for anterior subcutaneous transposition surgery were enrolled. Simple decompression, circumferential decompression, and anterior transposition of the ulnar nerve were performed during the course of the transposition procedure. Regional ulnar nerve strain around the elbow was measured for each surgical intervention based on 4 wrist and elbow joint configurations. With elbow extension at 180°, both circumferential decompression and anterior transposition resulted in approximately 68% higher nerve strains than simple decompression. Conversely, with elbow flexion, simple decompression resulted in higher average strains than anterior transposition. Limited regional differences in strain were observed for any surgical intervention with elbow extension. However, with elbow flexion, strains were higher in distal and central regions compared with the proximal region within all surgical groups, and proximal region strain was higher after simple decompression compared with anterior transposition. As predicted by the altered anatomic course, anterior transposition results in lower ulnar nerve strains than simple decompression during elbow flexion and higher nerve strains during elbow extension. Irrespective of anatomic course, circumferential release of paraneurial tissues may also influence nerve strain. Nerve strain varies regionally and is influenced by surgery and joint configuration. Our data provide insight into how surgery resolves and redistributes traction on the ulnar nerve. These

    Full Text Available Abstract Background Magnetic resonance (MR imaging is a useful diagnostic tool for the assessment of knee joint injury. Anterior cruciate ligament repair is a commonly performed orthopaedic procedure. This paper examines the concordance between MR imaging and arthroscopic findings. Methods Between February, 1996 and February, 1998, 48 patients who underwent magnetic resonance (MR imaging of the knee were reported to have complete tears of the anterior cruciate ligament (ACL. Of the 48 patients, 36 were male, and 12 female. The average age was 27 years (range: 15 to 45. Operative reconstruction using a patellar bone-tendon-bone autograft was arranged for each patient, and an arthroscopic examination was performed to confirm the diagnosis immediately prior to reconstructive surgery. Results In 16 of the 48 patients, reconstructive surgery was cancelled when incomplete lesions were noted during arthroscopy, making reconstructive surgery unnecessary. The remaining 32 patients were found to have complete tears of the ACL, and therefore underwent reconstructive surgery. Using arthroscopy as an independent, reliable reference standard for ACL tear diagnosis, the reliability of MR imaging was evaluated. The true positive rate for complete ACL tear diagnosis with MR imaging was 67%, making the possibility of a false-positive report of "complete ACL tear" inevitable with MR imaging. Conclusions Since conservative treatment is sufficient for incomplete ACL tears, the decision to undertake ACL reconstruction should not be based on MR findings alone.

    To assess the precision of laser anterior capsulotomy compared with that of manual continuous curvilinear capsulorhexis (CCC). Asociación Para Evitar La Ceguera en México IAP, Hospital Dr. Luis Sánchez Bulnes, Mexico City, Mexico. Nonrandomized single-center clinical trial. In patients presenting for cataract surgery, the LensAR Laser System was used to create a laser anterior capsulotomy of the surgeon's desired size. Capsule buttons were retrieved and measured and then compared with buttons retrieved from eyes having a manually torn CCC. Deviation from the intended diameter and the regularity of shape were assessed. When removing the capsule buttons at the start of surgery, the surgeon rated the ease of removal on a scale of 1 to 10 (1 = required manual capsulorhexis around the whole diameter; 10 = button free floating or required no manual detachment from remaining capsule during removal). The mean deviation from the intended diameter was 0.16 mm ± 0.17 (SD) for laser anterior capsulotomy and 0.42 ± 0.54 mm for CCC (P=.03). The mean absolute deviation from the intended diameter was 0.20 ± 0.12 mm and 0.49 ± 0.47 mm, respectively (P=.003). The mean of the average squared residuals was 0.01 ± 0.03 and 0.02 ± 0.04, respectively (P=.09). The median rating of the ease of removal was 9 (range 5 to 10). Laser anterior capsulotomy created a more precise capsule opening than CCC, and the buttons created by the laser procedure were easy to remove at the beginning of cataract surgery.

    higher incidence of postoperative inflammation and opacification of the optical axis has been reported after pediatric cataract surgery. Posterior capsular opacification is almost an unavoidable complication in children's eyes if the posterior capsule is left intact. Several methods have been proposed in order to keep the optical axis clear in infants and young children. Comparison of posterior capsulectomy with and without anterior vitrectomy showed that posterior capsular opacification rates are diminished only after combined posterior capsulectomy and anterior vitrectomy and not after capsulectomy alone. Posterior capsulorhexis with optic capture seems to effectively prevent posterior capsular opacification. This technique eliminates the need for anterior vitrectomy and ensures the centration of the intraocular lens. Glaucoma and retinal detachment are late complications of pediatric cataract surgery. On average glaucoma develops 6.8 years after cataract operation. Retinal detachment develops several decades after cataract extraction. The functional results after pediatric cataract surgery depend not only on the anatomic success of the operation and postoperative maintenance of a clear optical axis, but even more on aphakic visual rehabilitation. Children's eyes with cataract severe enough to require cataract extraction usually have some degree of amblyopia already present prior to surgery. In unilateral pseudophakia amblyopia develops postoperatively unless the fellow eye is occluded or optically and/or pharmacologically penalized. Immediate optical correction is desirable because prevention and/or therapy of amblyopia should be initiated directly after surgery. Parental compliance with occlusion therapy and not successful surgery are major determinants of a good visual outcome in unilateral aphakic/pseudophakic children.

    ulcer formation. On the other side, it is not clear what was the grade and morphology of the lens opacity, especially if it is known that visual acuity in right – healthy eye is 6/12 with presence of immature senile cataract. Retained IOFB is a risk factor for prolonged postoperative inflammation and endophthalmitis after cataract surgery. Therefore, surgical intervention including cataract extraction, foreign body removal with possible toric intraocular lens implantation could be therapy of choice for this patient. For these reasons, we would kindly ask the authors to present the data regarding the uncorrected visual acuity, required spherical and cylindrical correction, keratometry and refractometry readings, intraocular pressure values, grade and morphology of the lens opacification, state of the iridocorneal angle, possible changes in the vitreous, retina and optic nerve head. Without this information’s it would be difficult to hypothesize that the IOFB in the anterior chamber was completely inactive forthe past twenty years and it did not produce any adverse effect in patient’s eye. These findings will significantly contribute to the papers scientific value and contribution. Overall we agree with Surekha et al. that IOFBs can be variable in presentation and outcome. There is still significant controversy in the management of IOFBs, particularly the timing and method of surgery.

    The purpose of this study was to assess the correlations between dynamic postural stability and muscle strength, anterior instability, and knee scores in anterior cruciate ligament (ACL) deficient knees. We examined 40 male patients with ACL injury prior to surgery. Maximal torques of flexors and extensors of the injured knee at 60 and 180 degrees /s were evaluated using an isokinetic testing device. Anterior translations of the tibia were measured using a KT-2000 arthrometer, and dynamic postural stabilities were measured during single-leg stance using the Biodex Stability System (BSS). Knee statuses were evaluated using Lysholm and International Knee Documentation Committee (IKDC) knee scores. Correlations between dynamic postural stability and muscle strength, anterior instability, and knee scores were determined. Significant correlations were found between maximal torques of the extensor of injured knees at 60 and 180 degrees /s (r = -0.52, p = 0.048 and r = -0.46, p = 0.019, respectively) and dynamic postural stability, and maximal torques of flexors of injured knees showed similar relations (r = -0.51, p = 0.0048 and r = -0.47, p = 0.016, respectively). Lysholm and IKDC knee scores were also found to be correlated with dynamic postural stability (r = -0.49, p = 0.001 and r = -0.52, p = 0.005, respectively). However, no correlation was found between grade of anterior translation measured using the KT-2000 arthrometer and dynamic postural stability (p = 1.0). Dynamic postural stability determined using the BSS appears to be influenced by muscle strength, as determined by isokinetic testing, but not with grade of anterior translation measured using a KT-2000 arthrometer. Subjective knee scores appear to improve in parallel with dynamic postural stability.

  11. Holistic approach to understanding anterior knee pain. Clinical implications.

    2014-10-01

    Anterior knee pain is one of the most frequent reasons for consultation within knee conditions. The aetiology is not well known, which explains the sometimes unpredictable results of its treatment. Normally, when we see a patient in the office with anterior knee pain, we only study and focus on the knee. If we do this, we are making a big mistake. We must not forget to evaluate the pelvis and proximal femur, as well as the psychological factors that modulate the course of the illness. Both the pelvifemoral dysfunction as well as the psychological factors (anxiety, depression, catastrophization and kinesiophobia) must be included in our therapeutic targets of the multidisciplinary treatment of anterior knee pain. We must not only focus on the knee, we must remember to "look up" to fully understand what is happening and be able to solve this difficult problem. The aetiology of anterior knee pain is multifactorial. Therefore, diagnosis and treatment of patellofemoral disorders must be individualized. Our findings stress the importance of tailoring physiotherapy, surgery and psycho-educational interventions to each patient.

    1998-01-01

    A total of 33 patients submitted to tibial intramedullary osteosynthesis for fracture (27 cases) and non-union were assessed by ultrasound and x-rays an average of 10.9 months after surgery. The route of access was patellar transtendineal in each case; the means of synthesis used was the Marchetti Vicenzi nail. In 19 patients (57.6%) there was anterior gonalgia. Radiologic assessment evaluated prominence of the nail, while nail-tendon impingement was examined by ultrasound. Nail-tendon impingement was frequently observed (24 cases, 72.7%); in cases such as these anterior pain in the knee was present in 17 patients: however, this fact did not achieve statistical significance. The patellar tendon was thickened as compared to the contralateral one, with disorganization of the fibrillar echotexture, but it was not shortened. The tendinous morphostructure did not reveal any relationship with anterior gonalgia. In none of the cases did we observe the formation of scarring nuromas. In the area of the Hoffa body reactive synovitis phenomena with structural hyperechogenicity, an unclear aspect of the posterior tendinous profile and calcifications were observed.

    Full Text Available OBJETIVO: Avaliar a integridade do músculo subescapular através da força, função e ressonância nuclear magnética após acesso deltopeitoral para tratamento da luxação glenoumeral anterior recidivante. MÉTODOS: Foram avaliados 20 pacientes com luxação recidivante do ombro. Todos os casos possuíam seguimento mínimo de 12 meses, com média de 40 meses. Os pacientes eram todos do sexo masculino, com média de idade de 29 anos (20-42 anos. Os pacientes foram submetidos a exame físico para avaliar mobilidade, força muscular, "Belly" Teste e teste de Gerber. A força isocinética em rotação interna e externa, em velocidades angulares de 60º/s e 180º/s, em ambos os ombros, foi medida utilizando-se um dinamômetro. Em 15 pacientes foi realizada ressonância nuclear magnética (RNM em ambos os ombros para avaliação da espessura, área e possível hipotrofia do músculo subescapular. RESULTADOS: Houve diferença significativa entre os picos de torque para a velocidade de 60º/s para as rotações interna (p = 0,036 e externa (p = 0,008. Porém, para a velocidade de 180º/s a situação se inverte (rotação interna: p = 0,133; rotação externa: p = 0,393. A espessura e a área do subescapular são significativamente menores que as do lado normal, com déficit de 19% e 23%, respectivamente. De acordo com os escores de Rowe e da UCLA, observamos excelentes e bons resultados na maioria dos pacientes, com média de 88 e 31,6 pontos, respectivamente. CONCLUSÃO: Apesar dos bons resultados funcionais, a cirurgia aberta pode restringir a força, bem como reduzir a espessura e a área da seção transversal do músculo subescapular. Os melhores resultados ocorreram no lado dominante.OBJECTIVE: To evaluate the integrity of the subscapularis tendon by strength, function and magnetic resonance imaging after deltopectoralis access for anterior shoulder instability.

    2000-01-01

    A retrospective analysis of a consecutive series of 12 patients with 15 intracranial hemangiopericytomas treated at the University of Virginia using gamma surgery is presented. Clinical and radiographic follow up of 3 to 56 months is available for 10 patients with 12 tumors. There was one tumor present at the time of initial gamma surgery in each patient. Two new tumors occurred in patients previously treated. Nine of the tumors decreased in volume and three remained stable. Four of the nine tumors that shrank later progressed at an average of 22 months after treatment. Of the tumors that decreased in volume and have not progressed, the response has been for an average of 11 months. The follow-up for two tumors that remained unchanged was 10 and 34 months (average 22 months). A third tumor was unchanged at 42 months but the patient died of new disease adjacent to the treated area in the anterior skull base. There were no complications and the quality of life following the procedure was maintained or improved in every case. Gamma surgery is effective in palliating the patients by decreasing tumor volume and delaying recurrence. (author)

    Ligament reconstruction is the current standard of care for active patients with an anterior cruciate ligament (ACL) rupture. Although the majority of ACL reconstruction (ACLR) surgeries successfully restore the mechanical stability of the injured knee, postsurgical outcomes remain widely varied. Less than half of athletes who undergo ACLR return to sport within the first year after surgery, and it is estimated that approximately 1 in 4 to 1 in 5 young, active athletes who undergo ACLR will g...

    The authors retrospectively reviewed 33 cases of fracture involving the anterior colliculus of the medial malleolus to examine clinical results of operative treatment for these fractures. Although this injury appears innocuous, it can be difficult to obtain stable fixation of the fragment intraoperatively, and painful nonunion can result. A simple reduction maneuver and method of tension band fixation are described.

    2011-03-01

    The underlying etiology of anterior knee pain has been extensively studied. Despite many possible causes, often times the diagnosis is elusive. The most common causes in the young athlete are osteosynchondroses, patellar peritendinitis and tendinosis, synovial impingement, malalignment, and patellar instability. Less common causes are osteochondritis dissecans and tumors. It is always important to rule out underlying hip pathology and infections. When a diagnosis cannot be established, the patient is usually labeled as having idiopathic anterior knee pain. A careful history and physical examination can point to the correct diagnosis in the majority of cases. For most of these conditions, treatment is typically nonoperative with surgery reserved for refractory pain for an established diagnosis.

    Twenty mongrel dogs received 6000 rads of irradiation to the rectum and colon using the Nominal Standard Dosage Equation. Three weeks after irradiation each dog underwent anterior resection of the rectosigmoid with reconstruction randomized to either an EEA stapled or a two layer handsewn anastomosis. Each dog was studied digitally and by barium enema at the time of surgery, on the seventh postoperative day, and at autopsy. Five clinically significant leaks and three radiographic leaks occurred in the EEA stapled anastomoses. The handsewn anastomoses had five clinically significant leaks and two radiographic leaks. The data indicate that low anterior resection with either an EEA stapled or handsewn anastomosis cannot be done safely after 6000 rad preoperative irradiation.

    Palencar, Adrian J

    2016-01-01

    An anterior open bite is one of the most difficult occlusal abnormalities to treat. Quite often this aberration entails dental component and/or skeletal component. The skeletal open bite will require intrusion of the posterior sextants with the assistance of bite blocks, temporary anchorage devices, high pull headgear, and as a last resort - orthognathic surgery. The orthodontic treatment should be augmented with the orofacial myofunctional therapy. In this article, the author describes 3 different variations of treatment of the dental anterior open bite, first on acrylic models, and then on the actual patients. Consideration should be given to patients with a 'short upper lip," and in this case, surgical correction should be entertained.

    2002-01-01

    The aim of this study is to evaluate the eventual advantages of tibialis anterior (TA) tendon lengthening during clubfoot posteromedial release. A continuous series of 60 idiopathic clubfeet has been retrospectively studied. Tibialis anterior lengthening (TAL) began to be performed in 1984. Two groups of 30 feet have been distinguished: without TAL (before 1984) and with TAL (after 1984). There was no significant difference between the 2 groups concerning mean age at surgery, preoperative clinical and radiologic data. Mean postoperative follow-up was 10 years and minimal follow-up required was 5 years. TAL decreased Triceps surae relative insufficiency and improved monopodal jump. TAL balanced TA and peroneus longus, decreased dynamic supination and balanced forefoot pronation and supination. The feet without TAL presented lack of anteromedial support (20% without TAL, 0% with TAL) and medial arch cavus with dorsal talo-navicular subluxation (20% without TAL, 3,3% with TAL). TAL decreased the rate of recurrence and surgical revision.

    Young, E; Mitchell-Innes, A; Jindal, M

    2015-07-01

    Lasers in stapes surgery are used to divide the anterior and posterior crus of the stapes, divide the stapedius tendon and perforate the footplate. The ideal laser should not penetrate deeply into the perilymph (thereby increasing its temperature). It should be conducted through optical fibres, allowing easy manipulation, and should have good water absorption, equating to high bone ablation efficiency. This review discusses the various different lasers used in stapes surgery with regard to their properties and suitability for this type of surgery. In particular, the laser parameters used are discussed to facilitate their clinical use.

    Full Text Available Objetivo: apresentar os aspectos clínicos, diagnósticos e terapêuticos de pacientes portadores de válvula da uretra anterior. Descrição: em dois neonatos, o diagnóstico presuntivo de patologia obstrutiva do trato urinário foi sugerido pela ultra-sonografia realizada no período pré-natal, confirmando-se o diagnóstico de válvula de uretra anterior pela avaliação pós-natal. Os pacientes foram submetidos a tratamento cirúrgico paliativo, com vesicostomia temporária e, posteriormente, definitivo, pela fulguração endoscópica das válvulas. Ambos evoluíram com função renal normal. Comentários: a válvula da uretra anterior é anomalia rara que deve ser considerada em meninos com quadro radiológico pré-natal sugestivo de obstrução infravesical, secundariamente à hipótese mais comum de válvula da uretra posterior. Ressaltamos a utilização da vesicostomia como derivação urinária temporária nestes casos, prevenindo potenciais complicações pela manipulação da uretra do recém-nascido.Objective: to discuss clinical signs, diagnostic tools and therapeutics of anterior urethral valves, an obstructive anomaly of the urinary system in males. Description: signs of urinary tract obstruction were identified on pre-natal ultrasound in two male fetuses and the diagnosis of anterior urethral valves was made through post-natal evaluation. As an initial treatment, vesicostomy was performed in both patients. Later, the valves were fulgurated using an endoscopic procedure. During the follow-up period both patients presented normal renal function. Comments: anterior urethral valves are a rare form of urethral anomaly that must be ruled out in boys with pre-natal ultrasound indicating infravesical obstruction. Vesicostomy used as an initial treatment rather than transurethral fulguration may prevent potential complications that can occur due to the small size of the neonatal urethra.

    Percutaneous kyphoplasty is effective for pain reduction and vertebral height restoration in patients with osteoporotic vertebral fractures. However, in cases of severely collapsed fractures involving the loss of more than 70% of the vertebral height, kyphoplasty is technically difficult to perform and the outcomes remain unknown. To compare the vertebral height restoration rate, kyphotic angle, and clinical results of patients who underwent kyphoplasty according to the degree of anterior vertebral height loss. In addition, to determine the feasibility and effects of kyphoplasty on severely collapsed osteoporotic vertebral fractures. A retrospective study. A total of 129 patients (145 vertebrae) who underwent kyphoplasty for osteoporotic painful vertebral fracture and followed up for more than 1 year between September 2005 and August 2012 were recruited for the analysis. The patients' kyphotic angle, anterior vertebral height, and anterior vertebral height restoration ratio 1 year after surgery were compared. Pre- and postoperative pain around the fractured vertebra and the radiological and clinical results according to bone mineral density (BMD) were also compared. Patients were divided into three groups for comparison, according to radiographic findings. Patients with an anterior height compression ratio more than 70% at the time of fracture comprised Group I, patients with a compression ratio of 50-70% comprised Group II, and those with a compression ratio of 30-50% comprised Group III. Group I showed a greater extent of anterior height restoration immediately after surgery compared with the other groups, which noticeably decreased over time. All three groups showed significant restoration of the anterior vertebral height between pre- and postoperative values. The anterior vertebral height 1 year after surgery did not differ between Group I and Group II but was significantly higher in Group III. There was no correlation between the BMD and restoration or

    Full Text Available Objectives: To report the intraoperative and postoperative follow-up complications and management of these in deep anterior lamellar keratoplasty (DALK surgery. Materials and Methods: Two hundred eighty-four eyes of 252 patients followed up in our cornea clinic who underwent DALK using Anwar’s big-bubble technique with healthy Descemet’s membrane and endothelium were included in this study. Intraoperative and postoperative complications as well as the management and treatment of these complications were evaluated. Results: Big bubble was created in 220 (77.5% eyes of 284 eyes, and lamellar dissection was performed in 64 (22.5% eyes. Perforation occurred during trephination in 4 eyes, and the procedure was accomplished by penetrating keratoplasty (PK. Intraoperative microperforation occurred in 44 eyes. Perforation enlarged in 4 eyes and PK was performed. Operation was continued in 40 eyes with air injection into the anterior chamber. In postopertive follow-up period, double anterior chamber (DAC occurred in 32 of 40 eyes. DAC spontaneously regressed in 8 eyes, and air was given into the anterior chamber with a second surgical intervention in 24 eyes. DAC improved in 20 eyes. Four eyes underwent PK. Fungal keratitis evolved at the interface in one eye, because of no healing during the follow-up period, this eye underwent PK under antifungal therapy. Eyes with interface haze and Descemet’s membrane folds were followed. Conclusion: DALK is a difficult technique with a steep learning curve. In addition to the complications seen in PK, specific complications can occur in lamellar surgery. (Turk J Ophthalmol 2014; 44: 337-40

    This article introduces a technique combining corticotomy and orthodontic forces, or accelerated osteogenic orthodontics, for use in patients with a Class III occlusion and a thin alveolus who will undergo orthognathic surgery. Two adults with Class III malocclusion undergoing anterior decompensation for mandibular setback surgery were selected. The first patient was treated with accelerated osteogenic orthodontics and conventional decompensation. The second patient was treated with accelerated osteogenic orthodontics and decompensation with a temporary skeletal anchorage device in concert with guided tissue regeneration. Decortication of bone was performed to the mandibular teeth with a low-speed round bur and piezosurgery. After hemostasis, bone graft material was placed into the decorticated area. In the severely thin alveolar ridge, a rigid scaffold was applied for immobilization of graft material. After approximation of the flap, an immediate orthodontic force was applied to the teeth to initiate rapid tooth movement. Rapid tooth movement into predetermined positions for orthognathic surgery was accomplished in all mandibular anterior teeth. Preoperative 3-dimensional imaging showed dehiscences on the facial aspects of the mandibular anterior teeth. Postoperative imaging demonstrated coverage of the denuded roots with radiodense material. The accelerated osteogenic orthodontic technique is a safe and effective treatment option for mandibular anterior decompensation treatment of these patients. When combined with a temporary skeletal anchorage device and bone augmentation, this technique facilitated the decompression of the mandibular anterior teeth in severely compromised dentitions.

    In most cases, hydration is performed by water injection into the stromal tissue with a needle. The technique is simple, however it is sometimes troublesome. We describe a simple technique for hydrating the corneal stroma in cataract surgery using an irrigation port. The technique began by pushing the irrigation port against the corneal stroma for a few seconds during phacoemulsification, which generated edema in the corneal incision that subsequently prevented leakage. This procedure is called the hydration using irrigation port (HYUIP) technique. A total of 60 eyes were randomized and placed in two groups, 30 eyes underwent surgeries using the HYUIP technique (HYUIP group) and 30 eyes underwent surgeries without the HYUIP technique (control). The three points evaluated during each surgery included 1) the occurrence of anterior chamber collapse during the pulling out of the I/A tip after inserting the intraocular lens, 2) the need for conventional hydration, and 3) watertight completion at the end stage of surgery. The anterior chamber collapse and the need for conventional hydration were significantly smaller in the HYUIP group compared to the control group. Regarding the self-sealing completion, no significant difference was observed between the two groups. The HYUIP technique is an effective method for creating self-sealing wound. In addition, this technique helps to prevent anterior chamber collapse.

    Robotic surgery is a reality in several surgical fields, such as in gastrointestinal surgery. In ophthalmic surgery the required high spatial precision is limiting the application of robotic system, and even if several attempts have been designed in the last 10 years, only some application in retinal surgery were tested in animal models. The combination of photonics and robotics can really open new frontiers in minimally invasive surgery, improving the precision, reducing tremor, amplifying scale of motion, and automating the procedure. In this manuscript we present the preliminary results in developing a vision guided robotic platform for laser-assisted anterior eye surgery. The robotic console is composed by a robotic arm equipped with an "end effector" designed to deliver laser light to the anterior corneal surface. The main intended application is for laser welding of corneal tissue in laser assisted penetrating keratoplasty and endothelial keratoplasty. The console is equipped with an integrated vision system. The experiment originates from a clear medical demand in order to improve the efficacy of different surgical procedures: when the prototype will be optimized, other surgical areas will be included in its application, such as neurosurgery, urology and spinal surgery.

    Anterior chest wall involvement is not infrequently observed within inflammatory arthropaties, particularly if one considers seronegative spondyloarthritides and SAPHO syndrome. Physical examination is unreliable and conventional X-rays analysis is an unsatisfactory tool during diagnostic work-up of this region. Scintigraphic techniques yield informations both on the activity and on the anatomical extent of the disease while computerized tomography visualize the elementary lesions, such as erosions, which characterize the process. Moreover, when available, magnetic resonance imaging couple the ability to finely visualize such lesions with the possibility to show early alterations and to characterize the "activity" of the disease, presenting itself as a powerful tool both for diagnosis and follow-up. This review briefly shows the applications of imaging techniques for the evaluation of the anterior chest wall focusing on what has been done in the SAPHO syndrome which can be considered prototypical for this regional involvement since it is the osteo-articular target mainly affected by the disease.

    2012-01-01

    The Dutch Orthopaedic Association has a long tradition of development of practical clinical guidelines. Here we present the recommendations from the multidisciplinary clinical guideline working group for anterior cruciate ligament injury. The following 8 clinical questions were formulated by a steering group of the Dutch Orthopaedic Association. What is the role of physical examination and additional diagnostic tools? Which patient-related outcome measures should be used? What are the relevant parameters that influence the indication for an ACL reconstruction? Which findings or complaints are predictive of a bad result of an ACL injury treatment? What is the optimal timing for surgery for an ACL injury? What is the outcome of different conservative treatment modalities? Which kind of graft gives the best result in an ACL reconstruction? What is the optimal postoperative treatment concerning rehabilitation, resumption of sports, and physiotherapy? These 8 questions were answered and recommendations were made, using the “Appraisal of Guidelines for Research and Evaluation” instrument. This instrument seeks to improve the quality and effectiveness of clinical practical guidelines by establishing a shared framework to develop, report, and assess. The steering group has also developed 7 internal indicators to aid in measuring and enhancing the quality of the treatment of patients with an ACL injury, for use in a hospital or practice.

    Full Text Available Objective: To evaluate the surgical technique with bifrontal interhemispheric approach for total removal of tumor in olfactory groove meningioma (OGM. Methods: This study described a case of a 38-year-old woman with bilateral blindness, anosmia, and behaviour changes. Imaging studies show a tumor mass in midfrontal base. Surgery using a bifrontal interhemispheric approach was performed and total removal was achieved and postoperative computed tomography (CT scan was performed to confirm the result. Histopathological findings established a diagnosis of meningioma. Results: A coronal skin incision behind the hairline was utilized. The scalp was elevated, taking care to reserve the vascularized pericranium medial to the linea temporalis of each side, and preserving the 2 supraorbital nerves. Eight burr holes were used, with the two initial holes made on each side of the orbitotemporal region, and the other four holes at the midline. A bifrontal craniotomy was performed. The tumor was first detached from its attachment with bipolar cautery and debulked. During this step, the main tumor feeder arteries from the anterior and posterior ethmoidal artery were interrupted, and the tumor devascularized. Total tumor removal through surgical intervention was achieved and confirmed by head CT-scan postoperatively. Conclusions: This case report supports the suitability of the bifrontal interhemispheric approach for OGM resection with additional radiation therapy.

  8. Pseudoaneurysm of the anterior superficial temporal artery.

    Pseudoaneurysm of the superficial temporal artery must be considered in the differential diagnosis of masses of the lateral forehead and temporal fossa. While the first reported case of a temporal artery aneurysm was reported by Thomas Bartholin in 1740, there is scant mention of this lesion in the plastic and maxillofacial surgical literature. Pseudoaneurysms can arise in the forehead and scalp as a result of blunt traumatic impingement of the superficial temporal artery against the calvarium. The anterior branch of the artery is most vulnerable, because in the lateral forehead it courses over the frontal osseous ridge in the galea aponeurotica formed by the fusion line of the deep and superficial temporalis muscle fascia. This dense fascial investment has a tethering effect in the gap between the temporalis and frontalis muscles and prevents the artery from displacing laterally in response to traumatic forces. A history of recent blunt trauma or surgery to the forehead, combined with a pulsatile bruit, should direct the physician to the diagnosis of pseudoaneurysm of the superficial temporal artery. Treatment is surgical resection of the involved segment without the need for reconstruction. This report includes a review of the literature and presents the first documented case of a bicycle helmet as the cause of a superficial temporal artery pseudoaneurysm.

    Objective: Therapy for anterior combined with posterior urethral stricture is difficult and controversial. This study aims to introduce a standard process for managing anterior combined with posterior urethral stricture. Patients and methods: 19 patients with anterior combined with posterior urethral stricture were treated following our standard process. Average (range) age was 52 (21-72) years old. In this standard process, anterior urethral stricture should be treated first. Endoscopic surgery is applied for anterior urethra stricture as a priority as long as obliteration does not occur, and operation for posterior urethral stricture can be conducted in the same stage. Otherwise, an open reconstructive urethroplasty for anterior urethral is needed; while in this condition, the unobliterated posterior urethra can also be treated with endoscopic surgery in the same stage; however, if posterior urethra obliteration exists, then open reconstructive urethroplasty for posterior urethral stricture should be applied 2-3 months later. Results: The median (range) follow-up time was 25.8 (3-56) months. All 19 patients were normal in urethrography after 1 month of the surgery. 4 patients (21.1%) recurred urethral stricture during follow-up, and the locations of recurred stricture were bulbomembranous urethra (2 cases), bulbar urethra (1 case) and bladder neck (1 case). 3 of them restored to health through urethral dilation, yet 1 underwent a second operation. 2 patients (10.5%) complaint of dripping urination. No one had painful erection, stress urinary incontinence or other complications. Conclusions: The management for anterior combined with posterior urethral stricture following our standard process is effective and safe. PMID:26064293

    Full Text Available Conservative therapy is often the first-line treatment for many symptoms of various disease processes, including pain. Nevertheless, if pharmacological or medical management fails for those patients with severe and chronic pain, a surgical strategy may be a reasonable option. First performed for psychiatric disorders, cingulotomy now has been recognized as a viable option for the management of pain. The authors review the literature on anterior cingulotomy for intractable pain to provide guidelines for management and expected outcomes.

    Prolapse surgery has been shown to have major impact on sexual function. Since prolapse surgery not only influences psychological factors but might also influence physiological conditions such as vaginal innervation, there is a need for objective outcome measurements to better understand the effects of prolapse surgery on sexual function. To assess the effects of prolapse surgery with or without stress incontinence surgery on vaginal sensibility and to assess the relationship between vaginal wall sensibility and sexual well-being. This study was performed parallel to a randomized controlled trial comparing vaginal and abdominal prolapse surgery with or without incontinence surgery in women with uterine prolapse stage 2 or more. Vaginal wall sensibility was defined as mean sensation threshold to electrical stimulation of the vaginal wall at four standardized places, measured before and 6 months after surgery. Higher sensation thresholds postsurgery relative to presurgery indicate diminished vaginal wall sensibility. Sexual function was assessed at the same time points using a questionnaire. Data on vaginal wall sensibility were obtained from 65 patients. The sensibility of the distal posterior (P = 0.02) and distal anterior (P = 0.10) vaginal wall decreased after vaginal surgery compared to abdominal surgery. Abdominal prolapse surgery with incontinence surgery decreased sensibility of the distal part of the anterior vaginal wall significantly more than abdominal prolapse surgery only (P = 0.01). Before surgery, vaginal wall sensibility was lower in women who reported vaginal dryness or anorgasmia. The presence of genital pain was associated with higher vaginal wall sensibility. Postoperative vaginal wall sensibility was similar in women with and without sexual problems. Vaginal prolapse surgery as well as abdominal prolapse surgery with additional incontinence surgery resulted in decreased vaginal wall sensibility. This pilot study shows no influence of the

    Adjacent segment disease (ASD) is a well-recognized long-term outcome in patients with degenerative disease of the spine. In this manuscript, we focus on the development in ASD in patients who have undergone a prior anterior cervical discectomy and fusion (ACDF). Patient data were collected via clinical notes and patient interviews. Patients were followed for an average of 92.4 ± 72.6 months after the index ACDF. Of the 108 patients who underwent revision surgery due to symptomatic ASD, 77 patients underwent re-do ACDF, while 31 patients had posterior fusion surgery. Patients were more likely to be operated on posteriorly if they were older (P = 0.0115), male (P = 0.006), or had a higher number of cervical vertebral segments fused during the index ACDF (P = 0.013). These patients were statistically also more likely to exhibit myelopathic symptoms (P = 0.0053), and usually had worse neurologic function as assessed on the Nurick (P = 0.0005) and ASIA scales (P = 0.0020). Postoperatively, patients receiving anterior revision surgeries had higher rates of recurrent radiculopathy (P = 0.0425) and higher recurrence of ASD compared with patients fused posteriorly (P < 0.0001). Patients undergoing an anterior revision surgery for ASD after ACDF have higher rates of postoperative radiculopathy and redevelopment of ASD when compared with posteriorly approached patients. Patients receiving posterior revision surgery had higher intraoperative blood loss, hospitalizations, and postoperative complications such as wound infections and discharge to rehabilitation, but had a statistically lower chance of redevelopment of ASD requiring secondary revision surgery. This may be due to the fact that posterior revision surgeries involved more levels fused. This study provides one of the longest and most comprehensive follow-ups of this challenging patient population. Prospective studies comparing surgical approaches and techniques are needed to corroborate our findings.

    The anterior approach for C7-T1 disc herniation may be challenging because of obstruction by the manubrium and the narrow operative field. This study aimed to investigate the clinical and neurological outcomes of anterior approach for C7-T1 disc herniation. We retrospectively evaluated 13 patients who underwent the anterior approach for C7-T1 disc herniation by a single surgeon within a period of 11 years (2003-2014). The minimum follow-up duration was 6 months. We describe the clinical presentation, radiographic findings, neurological outcome, and related complications. Of 372 patients with single-level anterior discectomy and fusion or artificial disc replacement for cervical disc herniation, 13 (3.5%) had C7-T1 disc herniation. The main clinical presentation was unilateral motor weakness in intrinsic hand muscles (11 patients), along with numbness, pain, and tingling sensation that radiate down the arm to the little finger. Most of the patients improved after surgery via the anterior approach. Ten patients underwent successful anterior discectomy and fusion by the standard supramanubrial Smith-Robinson approach, but 2 needed additional manubriotomy and sternotomy. In 1 patient, we performed surgery at a wrong level because the correct level was difficult to identify intraoperatively. Two patients had transient vocal dysfunction, but none had major complications related to injuries of the great vessels such as the thoracic duct or esophagus. For patients who require direct anterior decompression for C7-T1 disc herniation, the anterior approach is relatively feasible. However, care should be taken to overcome physical constraints by the manubrium and slope.

    To evaluate the anatomical relation between anterior ethmoidal sinus and the lacrimal sac fossa, and thus help prevent complications during dacryocystorhinostomy. Fifty three people without previous history of trauma, surgery, or paranasal sinus disease were randomly selected, and the 106 lacrimal sac fossas of these subjects were evaluated by high resolution CT. A series of three 2-mm thick axial sections at least 2mm from the inferior orbital wall were obtained. The bony landmarks of the lacrimal sac fossa were established and the location of the most anterior ethmoid sinus was classified as one of three types. In type 1, no sinuses were anterior to the posterior lacrimal crest. While in type 2, sinuses extended anterior to this crest but remained behind the suture at the anterior edge of the lacrimal bone. In type 3, sinuses extended into the frontal process of the maxilla, anterior to the lacrimal bone suture. In addition, the category of both orbits of the same patient was compared. Among the 106 orbits examined, only seven (6.6%) were classified as type 1, with no ethmoid air cells postioned under the lacrimal sac fossa. Seventy six (71.7%) qualified as type 2, while the remaining 23 (21.7%) were type 3, demonstration anterior ethmoid air cells within the nasal process of the maxilla. The position of the air cells was symmetric in 41 of the 53 subjects (77.4%) and asymmetric in 12 (22.6%). In cases involving surgery of the lacrimal sac fossa, such as dacryocystorhinostomy, a knowledge of the consistent anatomic relationship between the anterior ethmoidal sinus and the lacrimal sac fossa is invaluable

    Congenital bilateral agenesis of the tibialis anterior muscles is a rare condition. We present a case of congenital absence of bilateral tibialis anterior muscles in a 6-year-old boy who presented with an abnormal gait. He was previously diagnosed to have bilateral congenital talipes equinovarus (CTEV) deformity for which he underwent corrective surgery two times. However, he still had a residual foot problem and claimed to have difficulty in walking. On examination, he walked with a high stepping gait and muscle power of both lower limbs was 5/5 on the medical research council scale (MRCS) except for both ankle dorsiflexors and long toe extensors. The sensation was intact. Magnetic Resonance Imaging (MRI) study of both legs revealed that tibialis anterior muscles were not visualized on both sides suggestive of agenesis of the tibialis anterior muscles. The rest of the muscles appeared mildly atrophied. The electrophysiological study showed normal motor and sensory conduction in both upper and lower limbs. Electromyographic (EMG) study of the vastus medialis was within normal limit and no response could be elicited for EMG of tibialis anterior muscles suggesting possible absence of tibialis anterior muscles, bilaterally. The patient underwent split tibialis posterior tendon transfer to achieve a balanced and functional foot and was well on discharge. The present case describes the normal anatomy and embryology of tibialis anterior muscles as well as possible causes of its agenesis along with its clinical implications.

    Abstract OBJECTIVE To review the management of bariatric surgical patients. QUALITY OF EVIDENCE MEDLINE, EMBASE, and Cochrane Library databases were searched, as well as PubMed US National Library, from January 1950 to December 2009. Evidence was levels I, II, and III. MAIN MESSAGE Bariatric surgery should be considered for obese patients at high risk of morbidity and mortality who have not achieved adequate weight loss with lifestyle and medical management and who are suffering from the complications of obesity. Bariatric surgery can result in substantial weight loss, resolution of comorbid conditions, and improved quality of life. The patient’s weight-loss history; his or her personal accountability, responsibility, and comprehension; and the acceptable level of risk must be taken into account. Complications include technical failure, bleeding, abdominal pain, nausea or vomiting, excess loose skin, bowel obstruction, ulcers, and anastomotic stricture. Lifelong monitoring by a multidisciplinary team is essential. CONCLUSION Limited long-term success of behavioural and pharmacologic therapies in severe obesity has led to renewed interest in bariatric surgery. Success with bariatric surgery is more likely when multidisciplinary care providers, in conjunction with primary care providers, assess, treat, monitor, and evaluate patients before and after surgery. Family physicians will play a critical role in counseling patients about bariatric surgery and will need to develop skills in managing these patients in the long-term. PMID:20841586

    2016-09-01

    The objective of this study was to estimate risk factors that influence postoperative instability after anterior cruciate ligament (ACL) reconstruction using multivariate logistic regression analysis. A total of 152 consecutive patients with symptomatic ACL insufficiency underwent arthroscopic ACL reconstruction between 2005 and 2011. Loss to follow-up and previous ligament reconstruction were exclusion criteria, resulting in 131 patients remaining for this retrospective study. The median follow-up was 55 months (range 25-100 months). Patients were sorted into two groups by anterior translation on stress radiograph and pivot shift test grade and were analysed for the statistical significance of various risk factors including age at surgery, gender, body mass index, preoperative instability, time from injury to surgery, single-bundle reconstruction with preserved abundant remnant versus double-bundle reconstruction with scanty remnant, and concomitant ligament, meniscus, and articular cartilage injury with use of multivariate logistic regression analysis. Time from injury to surgery over 12 weeks was found to be a significant risk factor for postoperative instability [p ligament (MCL) was also a risk factor (p = 0.02, adjusted OR 13.60; 95 % CI 1.24-148.25). The other variables were not found to be a significant risk factor. Among the risk factor variables, concomitant grade 2 MCL injury and surgical delay of more than 12 weeks from injury were significant risk factors for postoperative knee instability after ACL reconstruction. The overall results suggest that surgery <12 weeks from injury and meticulous attention to concomitant MCL injury should be considered. Retrospective case-control study, Level III.

    2014-01-01

    Surgical robotic systems have been available for almost twenty years. The first surgical robotic systems were designed as supportive systems for laparoscopic approaches in general surgery (the first procedure was a cholecystectomy in 1987). The da Vinci Robotic System is the most common system used for robotic surgery today. This system is widely used in urology, gynecology and other surgical disciplines, and recently there have been initial reports of its use in spine surgery, for transoral access and anterior approaches for lumbar inter-body fusion interventions. SpineAssist, which is widely used in spine surgery, and Renaissance Robotic Systems, which are considered the next generation of robotic systems, are now FDA approved. These robotic systems are designed for use as guidance systems in spine instrumentation, cement augmentations and biopsies. The aim is to increase surgical accuracy while reducing the intra-operative exposure to harmful radiation to the patient and operating team personnel during the intervention. We offer a review of the published literature related to the use of robotic systems in spine surgery and provide information on using robotic systems.

  7. Multi-channel motor evoked potential monitoring during anterior cervical discectomy and fusion

    Directory of Open Access Journals (Sweden)

    Dong-Gun Kim

    Full Text Available Objectives: Anterior cervical discectomy and fusion (ACDF surgery is the most common surgical procedure for the cervical spine with low complication rate. Despite the potential prognostic benefit, intraoperative neurophysiological monitoring (IONM, a method for detecting impending neurological compromise, is not routinely used in ACDF surgery. The present study aimed to identify the potential benefits of monitoring multi-channel motor evoked potentials (MEPs during ACDF surgery. Methods: We retrospectively reviewed 200 consecutive patients who received IONM with multi-channel MEPs and somatosensory evoked potentials (SSEPs. On average, 9.2 muscles per patient were evaluated under MEP monitoring. Results: The rate of MEP change during surgery in the multi-level ACDF group was significantly higher than the single-level group. Two patients from the single-level ACDF group (1.7% and four patients from the multi-level ACDF group (4.9% experienced post-operative motor deficits. Multi-channel MEPs monitoring during single and multi-level ACDF surgery demonstrated higher sensitivity, specificity, positive predictive and negative predictive value than SSEP monitoring. Conclusions: Multi-channel MEP monitoring might be beneficial for the detection of segmental injury as well as long tract injury during single- and multi-level ACDF surgery. Significance: This is first large scale study to identify the usefulness of multi-channel MEPs in monitoring ACDF surgery.

    Full Text Available En la práctica y desarrollo de la cirugía ortognática en el Hospital Universitario "Comandante Manuel Fajardo" a lo largo de los años, la morbilidad de diferentes anomalías del desarrollo maxilo-mandibulares ha mostrado que la adaquia o mordida abierta anterior es bastante frecuente. Desde tempranas edades se detectan y son tratadas por el especialista en Ortodoncia. El cerrar una adaquia en ocasiones se torna difícil y es cuando el análisis del paciente debe realizarse en el grupo multidisciplianrio integrado por cirujanos maxilofaciales, ortodoncistas y protesistas. Se han detectado diferentes causas que pueden producir una adaquia y en su mayor parte son hábitos nocivos que perduran en el paciente; por ejemplo, la interferencia con el centro de crecimiento condilar, la succión del pulgar, la deglución atípica o lengua protractil, la respiración bucal, entre otras. Este trabajo está encaminado en mostrar los diferentes tratamientos que en la actualidad se emplean para reducir una mordida abierta anterior y presenta el caso de una niña de 14 años de edad portadora de una adaquia de más de 18 mm.In the context of orthognathic surgery practice and development at "Comandante Manuel Fajardo" university hospital, morbidity from several anomalies in the maxillomandibular growth has shown that anterior open bite is pretty common. Such anomalies are detected and treated by the orthodontist at early childhood. To close an anterior open bite is difficult sometimes and requires the analysis of the patient by a multidisciplinary group made up of maxillofacial surgeons, orthodontists and denture specialists. A number of causes may be the origin of anterior open bite, mainly harmful habits that persist in the patient such as interference with the condylar growth center, dummy sucking, atypical deglutition or proctatile tongue, mouth breathing, among others.

    1994-01-01

    We reviewed out experience of sonourethrography(SUG) in male anterior urethral strictures to correlate the stricture length and degree seen on SUG with those on urethroscopy, surgery or biopsy. During the recent 6 years,both the retrograde urethrography (RUG) and SUG were preformed in 50 occasions for 47 patients with anteriorurethral stricture, that were subsequently evaluated urethroscopically or at surgery. As a whole, the length of the stricture seen on SUG did not correlate very well with that seen on RGU (r2=0.71, p<0.005). Considering the data from the operation as the gold standard, SUG was more accurate than RUG in depicting the exact stricturelength (r2=0.97 and 0.75 respectively,p<0.005). The shorter the lesion, the more accurate the data obtained.Although SUG certainly identified periurethral tissue, it was not adequate in predicting the depth of spongiofibrosis compared with full-depth biopsies in 20 patients. In conclusion, SUG, a dynamic study, accurately defined the stricture site, number and calibre. When compared with RUG, SUG was more accurate in the measurement of stricture length and in the demonstration of periurethral tissue, making it a valuable method in the evaluation of patients with suspected anterior urethral strictures

    Video assisted thoracic surgery (VATS) is a new modality which allows visualization of, and access to the intrathoracic organs without thoracotomy. Recently, this technique has been used for anterior thoracic spine approach to perform surgery which previously required standard postero-lateral thoracotomy. The authors report their initial experience of anterior spinal fusion using thoracoscopy and give a detailed description of their surgical procedure. This technique, started on June 1993, was performed only in one level 1 in 10 patients who had thoracic spine trauma with fracture or luxation. The procedure was performed in the lateral decubitus position. The patient was prepared in the standard manner for a full thoracotomy. Surgical instruments that are needed for conversion to an open procedure must be in the operative room. Ventilation was stopped to the ipsilateral lung. Lung's collapse of the surgical side was obtained with a double lumen tube. Carbon dioxide (CO2) insufflation was used to further collapse. The first thoracoscopic portal was placed through the sixth or seventh intercostal space in the posterior axillary line, which was the safest place. All subsequent portals were placed under thoracoscopic visualization, in a triangular way as recommended by Landreneau (1992). Only open trocars were used to avoid complication of CO2 insufflation. Once the target level has been defined, a needle was placed into the disc space and roentgenographic confirmation obtained. The parietal pleura was then divided using monopolar electrocautery. Segmental vessels of the operation field lied transversely across the midportion of the vertebral body. They were mobilised and systematically ligated with endoscopic clip to simplify the procedure. Then the intervertebral space was opened and bone and disc were removed, restricted to the anterior and middle third. The graft was placed into the thoracic cavity by using a high density calcium hydroxyapatite ceramic block

  15. Nonpenetrating glaucoma surgery with goniosynechiolysis ab interno: a surgical technique.

    2009-01-01

    To present a surgical technique for treatment of peripheral anterior synechiae (PAS or goniosynechiae) at the operative field during nonpenetrating glaucoma surgery. After usual preparation of a superficial and a deep scleral flap with externalization of the Schlemm's canal and peeling the juxtacanalicular trabecular meshwork, the goniosynechia is transected by a spatula introduced to the anterior chamber through a paracentesis. A Descemet's window provides full visual control at the peripheral cornea at the basis of the superficial scleral flap. With this surgical technique, selective treatment of goniosynechiae is possible exactly at the area where creation of low outflow resistance is intended by the surgeon during nonpenetrating glaucoma surgery. This technique enables the surgeon to perform nonpenetrating glaucoma surgery even in the presence of peripheral anterior synechiae.

    To report three cases of transient paralysis shortly after (within 4 hours) anterior cervical corpectomy and fusion (ACCF), and investigate the possible causes. Clinical and radiological data of three cases (two men and one woman, aged 41-61 years) were analyzed retrospectively. All three patients underwent ACCF for cervical spondylotic myelopathy. The decompressed segments were located in C(5) , C(6) and C(5) + C(6-7) discs, respectively. Paralysis occurred from 30 minutes to 4 hours after surgery. In two cases the paralysis was complete; it was incomplete in the third. All patients received immediate dehydration, neurotrophic drugs and high-dose methylprednisolone therapy upon recognition of their paralysis. Meanwhile, cervical MRIs were performed and showed no significant hematomas compressing the cervical spinal cord; spinal cord edema was clearly evident in all cases. In two cases the paralysis resolved within 2 hours of diagnosis and immediate medication. In the third case, because the neurological symptoms were incompletely resolved 24 hours after beginning medication, a second laminoplasty was performed. During decompression, tremendous pressure was released from the cervical spinal cord. The neurological symptoms had resolved completely by 1 week after decompression. The precise cause for transient paralysis after these anterior cervical surgeries is not yet clear. Spinal cord ischemia-reperfusion injury is generally regarded as the most likely cause. Therefore, a combination of cervical spinal cord edema and limited anterior decompression space may have been the main contributing factors to the paralysis reported here. Early diagnosis and early intervention to relieve the paralysis can restore spinal cord function and result in a satisfactory prognosis. © 2013 Chinese Orthopaedic Association and Wiley Publishing Asia Pty Ltd.

    The optimal management of anterior shoulder instability in athletes continues to be a challenge. The present study aimed to evaluate the functional outcomes of athletes with anterior shoulder instability following modified Latarjet reconstruction through assessing the timing of return to sport and complications. Retrospective assessment was performed of athletes (n = 56) who presented with recurrent anterior shoulder instability and were treated with modified congruent arc Latarjet reconstruction over a 1-year period. Rugby union was the predominant sport performed. Pre-operative instability severity index scores were assessed. Postoperative complications were recorded as was the time taken for the athlete to return to sport. Arthroscopic evaluation revealed that 86% of patients had associated bony lesions affecting the glenohumeral joint. The overall complication rate relating to the Latarjet reconstruction was 7%. No episodes of recurrent shoulder instability were noted. Of the patients, 89% returned to competitive sport at the same level as that prior to surgery. The mean time post surgery to returning to full training was 3.2 months. The modified congruent arc Latarjet procedure facilitates early rehabilitation and return to sport. These results support our systematic management protocol of performing modified Latarjet surgery in contact sport athletes with recurrent anterior instability.

    The high demands to the glenohumeral joint and the violent shoulder blows experienced during martial arts (MA) could compromise return to sports and increase the recurrence rate after arthroscopic stabilization for anterior shoulder instability in these athletes. To report the functional outcomes, return to sports, and recurrences in a series of MA athletes with anterior shoulder instability treated with arthroscopic stabilization with suture anchors. Case series; Level of evidence, 4. A total of 20 consecutive MA athletes were treated for anterior shoulder instability at a single institution between January 2008 and December 2013. Range of motion (ROM), the Rowe score, a visual analog scale (VAS), and the Athletic Shoulder Outcome Scoring System (ASOSS) were used to assess functional outcomes. Return-to-sport and recurrence rates were also evaluated. The mean age at the time of surgery was 25.4 years (range, 18-35 years), and the mean follow-up was 71 months (range, 36-96 months). No significant difference in preoperative and postoperative shoulder ROM was found. The Rowe, VAS, and ASOSS scores showed statistical improvement after surgery ( P < .001). In all, 19 athletes (95%) returned to sports. However, only 60% achieved ≥90% recovery after surgery. The recurrence rate was 20%. In this retrospective study of a consecutive cohort of MA athletes, arthroscopic anterior shoulder stabilization significantly improved functional scores. However, only 60% of the athletes achieved the same level of competition, and there was a 20% recurrence rate.

    The most important target of minimally invasive surgery is to obtain the best therapeutic effect with the least iatrogenic injury. In this background, a pivotal role in contemporary neurosurgery is played by the supraorbital key-hole approach proposed by Perneczky for anterior cranial base surgery. In this article, it is presented as a possible valid alternative to the traditional craniotomies in anterior cranial fossa meningiomas removal. From January 2008 to January 2012 at our department 56 patients underwent anterior cranial base meningiomas removal. Thirty-three patients were submitted to traditional approaches while 23 to supraorbital key-hole technique. A clinical and neuroradiological pre- and postoperative evaluation were performed, with attention to eventual complications, length of surgical procedure, and hospitalization. Compared to traditional approaches the supraorbital key-hole approach was associated neither to a greater range of postoperative complications nor to a longer surgical procedure and hospitalization while permitting the same lesion control. With this technique, minimization of brain exposition and manipulation with reduction of unwanted iatrogenic injuries, neurovascular structures preservation, and a better aesthetic result are possible. The supraorbital key-hole approach according to Perneckzy could represent a valid alternative to traditional approaches in anterior cranial base meningiomas surgery. PMID:26804334

    Full Text Available Background: In almost six decades different surgical techniques have been developed to treat patients with morbid obesity. Various surgical techniques are generally divided with respect to their effect into restrictive, malabsorbtive and humoral and a combination of these. Surgically modified human metabolism ameliorates metabolic diseases, particularly diabetes, even in nonobese patients. The understanding of metabolic effects changed the traditional paradigm of bariatric surgery from simple weight-loss procedure to metabolic surgery affecting whole-body metabolism. Proper surgical technique for individual patient is the most important factor influencing long- term results, comorbidities and quality of life. Recommendations for patient selection, surgical methods and pre- and postoperative patient management are to be respected. Metabolic surgery principles and current concepts are presented.

  2. Role of allografts in spinal surgery

    International Nuclear Information System (INIS)

    Aziz Nather

    1999-01-01

    With development of more tissue banks in the region and internationally, allografts are increasingly being used in orthopaedic surgery including spinal surgery. Two groups of patients will particularly benefit from the use of allografts. The first group is young children in whom iliac crest is cartilaginous and cannot provide sufficient quantity of autografts. The second is the elderly where bones from iliac crest are porotic and fatty. Allografts are used to fulfill two distinct functions in Spinal Surgery. One is to act as a buttress for anterior spinal surgery using cortical allografts. The other is to enhance fusion for posterior spinal surgery. Up to December 1997, 71 transplantations have been performed using allografts from NUH Tissue Bank. Anterior Spinal Surgery has been performed in 15 cases. The indications are mainly Trauma-Burst Fractures and Spinal Secondaries to the Spine. All cases are in thoracic and thoracolumbar region. Allografts used are deep frozen and freeze-dried cortical allografts. Femur is used for thoraco-lumbar region and humerus for upper thoracic region. Instrumentation used ranged from anterior devices (Canada, DCP, Synergy etc) to posterior devices (ISOLA). Deep frozen allografts and more recently freeze-dried allografts are preferred especially for osteoporotic spines. Cortical allografts are packed with autografts from ribs in the medullary canal. Allograft-autograft composites are always used to ensure better incorporation. Postero-lateral fusion has been performed for 56 cases. The indications include congenital and idiopathic scoliosis, degenerative stenosis, degenerative spondylolisthesis, spondylolytic spondylolisthesis, fracture-dislocation, osteoporotic burst fracture, spinal secondaries with cord compression and traumatic spondylolisthesis. Deep frozen bone allografts are used in combination with patient's own autografts from spinous processes to provide a 50% mix. Instrumentation used include Hartshill, Steffee, Isola

    Full Text Available Deep anterior lamellar keratoplasty (DALK using Dr. Anwar′s big bubble technique was performed for a patient with granular dystrophy. Intraoperatively, a perforation of the Descemet′s membrane (DM was noted inferonasally. Though the surgery was completed, the donor graft appeared to have an intact endothelium, which was inadvertently left behind by the surgeon. Intraoperatively, there was a perforation of inferonasal DM and surgery was completed by inadvertently placing a donor with an intact endothelium. Postoperatively the patient presented with a complete DM detachment and a resultant double anterior chamber (DAC. In spite of two attempts at an air tamponade on the first and fifth post operative days, the DAC still persisted. Surprisingly, during the 6 th week follow up visit, there was a complete resolution of the DAC as well as total recovery of vision. This interesting case clearly exemplifies that, in spite of failed attempts at air tamponade, a DM detachment and a DAC due to DM perforation following a DALK procedure can resolve spontaneously with good visual outcome.

  4. Anterior chest wall examination reviewed

    Full Text Available Anterior chest wall involvement is not infrequently observed within inflammatory arthropaties, particularly if one considers seronegative spondiloarthritides and SAPHO syndrome. Physical examination is unreliable and conventional X-rays analysis is an unsatisfactory tool during diagnostic work-up of this region. Scintigraphic techniques yield informations both on the activity and on the anatomical extent of the disease while computerized tomography visualize the elementary lesions, such as erosions, which characterize the process. Moreover, when available, magnetic resonance imaging couple the ability to finely visualize such lesions with the possibility to show early alterations and to characterize the “activity” of the disease, presenting itself as a powerful tool both for diagnosis and follow-up. This review briefly shows the applications of imaging techniques for the evaluation of the anterior chest wall focusing on what has been done in the SAPHO syndrome which can be considered prototypical for this regional involvement since it is the osteo-articular target mainly affected by the disease.

    Esquivel-Miranda, Miguel; De la O Ríos, Elier; Vargas-Valenciano, Emmanuelle; Moreno-Medina, Eva

    Schwannomas are nerve sheath tumours that originate in Schwann cells. They are usually solitary and sporadic and manifest on peripheral, spinal or cranial nerves. Intracranial schwannomas tend to manifest on the eighth cranial nerve, particularly in patients with neurofibromatosis type2. Anterior skull-base schwannomas represent less than 1% of all intracranial schwannomas. They are more frequent in young people and are typically benign. These tumours represent a diagnostic challenge due to their rarity and difficult differential diagnosis, and numerous theories have been postulated concerning their origin and development. In this article, we present the case of a 13-year-old male with a single anterior cranial-base tumour not associated with neurofibromatosis who presented with headache, papilloedema, eye pain and loss of visual acuity. Complete resection of the tumour was performed, which was histopathologically diagnosed as a schwannoma. The patient made a complete clinical recovery with abatement of all symptoms. We conducted a review of the literature and found 66 cases worldwide with this diagnosis. We describe the most relevant epidemiological and clinical characteristics of this kind of tumour and its relation with the recently discovered and similar olfactory schwannoma.

    Prospective clinical trial in thoracolumbar trauma with 5-year follow-up. To analyze clinical and radiographic outcomes of minimal invasive surgery, and the rational of circumferential fracture treatment with regard to age, degenerative changes, bone mineral density, and global sagittal balance. Non-neurologic fractures with anterior column defect can be treated by posterior percutaneous instrumentation and selective anterior fusion. After consolidation, instrumentation can be removed at 1 year to provide mobility in non-fused segments. Fifty-one patients, 47 (18-75) years, were operated for A2, A3, or B-type fractures. Visual analog scale (VAS) for back pain and Oswestry Disability Index (ODI) were assessed. Radiographic measurements were: sagittal index, regional kyphosis, T4-T12 kyphosis, L1-S1 lordosis, pelvic incidence, pelvic tilt, sacral slope, and T9 tilt. Anterior fusion and facet joints were analyzed on computed tomography (CT) at 1 year. The ODI was 8.8 before accident, 35.4 at 3 months, 17.8 at 2 years, 14.4 at 5 years. The VAS was 2.0 at 3 months and 1.0 at 5 years. The sagittal index was 18.0° preoperatively and 1.0° at 3 months (P fractured vertebra fused regularly. Spontaneous facet joint fusions were observed in two patients at the fracture level in B-type injuries. Percutaneous instrumentation and selective anterior fusion using autologous bone and mesh cages lead to high fusion rates, which provided good long-term clinical results in younger patients with thoracolumbar fractures. Sagittal alignment was maintained after instrumentation removal without damaging paravertebral muscles. Outcomes were worse in elderly patients presenting osteopenia or osteoporosis. 3.

    Full Text Available Purpose: Intense inflammation after cataract surgery can cause cystoid macular edema, posterior synechia and posterior capsule opacification. This experimental study was performed to investigate the effect of air bubble on inflammation when given to anterior chamber of rabbit eyes after cataract surgery. Materials and Methods: 30 eyes of 15 rabbits were enrolled in the study. One of the two eyes was in the study group and the other eye was in the control group. After surgery air bubble was given to the anterior chamber of the study group eye and balanced salt solution (BSS; Alcon was left in the anterior chamber of control eye. Results: On the first, second, fourth and fifth days, anterior chamber inflammations of the eyes were examined by biomicroscopy. On the sixth day anterior chamber fluid samples were taken for evaluation of nitric oxide levels as an inflammation marker. When the two groups were compared, in the air bubble group there was statistically less inflammation was seen. (1, 2, 4. days P = 0,001, and 5. day P = 0,009. Conclusions: These results have shown that when air bubble is left in anterior chamber of rabbits′ eyes after cataract surgery, it reduced inflammation. We believe that, air bubble in the anterior chamber may be more beneficial in the cataract surgery of especially pediatric age group, uveitis patients and diabetics where we see higher inflammation. However, greater and long termed experimental and clinical studies are necessary for more accurate findings.

    Anterior knee pain (AKP) is one of the most common complications after tibia intramedullary surgery. We evaluated changes in patellar tendon length after tibia intramedullary nailing surgery using a transtendinous approach and assessed the importance of nail position in relation to the anterior tibial cortex and joint line. Two surgeons blinded to patients' pain status measured both the knee Insall-Salvati and Caton-Deschamps indexes on 30° flexion lateral knee X-rays of 33 patients. Superior nail prominence (the distance from the proximal tip of the nail to the tibial plateau) and anterior nail prominence (the distance from the anterior tip of the nail to the anterior tibial cortex) were measured on the CT. Clinical assessment showed that 10 patients (30 %) had AKP at the last follow-up. HSS and Lysholm scores and the incidence of AKP were similar between patients whose IM nails were removed and those who still had them. HSS score, Insall-Salvati, and Caton-Deschamps indexes were significantly lower in the operated extremity than in the healthy limb at last follow-up. No association was demonstrated between AKP and nail position in relation to the anterior tibial cortex or tibial plateau. According to our study, although the patellar tendon shortened significantly on the affected side compared with the contralateral side, these measurements did not correlate with the presence or absence of pain. AKP and functional knee scores after tibia IM nailing using a transtendinous approach were not associated with nail position in relation to the anterior tibial cortex or tibial plateau.

    Yuichiro Yoneoka, MD, PhD

    2014-06-01

    Conclusion: To the best of our knowledge, ours is the only case of a dermoid cyst anchored to the anterior optic chiasma, which was visually confirmed under endoscopic observation. After surgery, the patient presented a transient impairment of the visual field, which was not evident at four month follow-up. It will contribute to a similar case, in which surgeons hesitate to make an incision in the optic chiasm. A subtotal excision should be considered in cases of dermoid cysts anchored to the anterior optic chiasm, because all the previously reported cases of suprasellar dermoid cysts are young people or those who have a relatively long life expectancy.

    Full Text Available Background: Primary actinomycosis of the anterior abdominal wall and appendix are very rare clinical entities. An accurate diagnosis is generally obtained by histological examination, and treatment often requires surgical resection. Case Report: In this study we presented two cases of primary actinomycosis involving the anterior abdominal wall and a third one located in the appendix. Conclusion: Actinomyces Israelii can involve all anatomic structures of the abdomen. Although preoperative diagnosis is difficult, the combination of surgery and antibiotic treatment results in complete treatment in the majority of cases.

    Full Text Available Although several risk factors for anterior cruciate ligament (ACL injury have been evaluated in the literature, there are few reports on familial predisposition. This study investigated the familial predisposition to ACL injury. The study included 350 patients who underwent ACL reconstruction between January 2005 and September 2008. All patients were surveyed by telephone or a written questionnaire about family history (FH of ACL injury, sports played by family members, and mechanisms of injury. We also compared age, sex, height, weight, body mass index, Tegner activity score, general joint laxity, and tibial slope between an FH group (with FH and a control group (without FH. In addition, we compared the incidence of ACL graft rupture and contralateral ACL rupture 2 years after primary surgery. Complete information was obtained from 316 patients, 38 (12.0% of whom had FH of ACL injury. Two families had three members with ACL injuries. Of the 40 family members with ACL injuries, 38 (95% had noncontact injuries and 34 (85% shared a similar mechanism of injury with the related patient. No significant differences were identified between the two groups, except that tibial slope was significantly greater in the FH group than in the control group. Although the incidence of repeat ACL injury was greater in the FH group (23.7% than in the control group (16.4%, there was no significant difference. Our results indicated a high probability of familial predisposition to many of the identified risk factors for ACL injury. In addition, patients with FH of ACL injury might be at high risk for initial and repeat ACL injuries. Therefore, prevention programs should be implemented for patients with FH of ACL injury in order to decrease the risk of these injuries.

    The aim of this study was to analyse the evolution of the isokinetic performance of the knee flexor and extensor muscles in soccer players before and after intra-articular anterior cruciate ligament reconstruction (Kennet-Jones). Two isokinetic evaluations were carried out before surgery and after rehabilitation (i.e. 4 months later) in 18 soccer players. The initial evaluation showed that the stabilizing muscles of the knee were affected differently after lesion of the external anterior crossed ligament. At the opposite of the flexor muscles, the performance of the knee extensor muscles of the injured leg was significantly reduced as compared with that of the healthy leg (peak torque at 90 degrees /s, -16%; power at 180 degrees /s, -14%; total work at 240 degrees /s, -11%). Even if 4 months after surgery, this deficit was accentuated (peak torque at 90 degrees /s, -26%; power at 180 degrees /s, -23%; total work at 240 degrees /s, -19%), the preoperative results of the knee extensor muscle do not condition the postoperative performance. After a rupture of the external anterior crossed ligament, a regular program of isokinetic evaluation of the knee seems to be relevant in the follow-up of the wounded athlete. The evaluation before surgery can be used as reference, and from a psychological point of view, this evaluation can create confidence in the athlete during hospitalization. A second evaluation 4 months after surgery can be used to quantify the muscular deficit to direct the exercises of rehabilitation.

    Full Text Available O carcinoma epidermóide da laringe é a sexta neoplasia mais comum, sendo uma das neoplasias malignas mais freqüentes na cabeça e pescoço, ocupando o segundo lugar imediatamente após o câncer da cavidade oral. FORMA DE ESTUDO: Estudo clínico retrospectivo. MATERIAL E MÉTODO: Entre os anos de 1991 e 2003, 24 pacientes portadores de lesões glóticas envolvendo a comissura anterior foram submetidos a laringectomia frontal anterior com epiglotoplastia descrita por Tucker e colaboradores no ano de 1979. RESULTADO: Nossos resultados confirmam aqueles encontrados em outras publicações. Não ocorreram mortes no pós-operatório e o seguimento foi relativamente simples. Todos os pacientes foram decanulizados e recuperaram um efetivo trato digestivo e aéreo. CONCLUSÃO: Nossos achados mostram que a laringectomia pela técnica de Tucker é uma cirurgia efetiva para o tratamento dos carcinomas glóticos que acometem a comissura anterior e a porção membranosa das cordas vocais com a motilidade preservada, pois tais lesões não devem ser tratadas pela ressecção endoscópica trans-oral ou por uma laringectomia fronto lateral.Squamous cell carcinoma of the larynx is the sixth most common neoplasia, being the second neoplasia of the head and neck, after oral cancer. STUDY DESIGN: Retrospective clinical study chart review. MATERIAL AND METHOD: From 1991 to 2003, 24 patients whose glottic lesions involving anterior comissure were operated with a reconstructive anterior frontal laryngectomy with epiglotoplasty, such as described by Tucker et al in 1979. RESULTS: Our functional results confirm those reported in the previous publications. There were no post-operative mortalities and follow-up was usually uncomplicated. All patients underwent decanulation and were able to eat by tract normal. CONCLUSION: Our findings show that partial laryngectomy by Tucker's technique is an effective surgical approach for glottic carcinoma at the anterior comissure

    PurposeTo determine the proper time for traumatic cataract surgery after open globe injuries.SettingFarabi Eye Hospital, Tehran University of Medical Sciences, Tehran, Iran.DesignRandomized clinical trial.Patients and methodsIn a randomized clinical trial, 30 eyes with traumatic cataract after open globe injury with IOL implantation underwent early (in the first week after the trauma) and 30 eyes underwent late cataract surgery (from the first to second month after the trauma). We excluded patients who were under 12-year-old. All patients were visited at 1 week, 4 weeks, 12 weeks, and 6 months after surgery. In each visit, patients were examined regarding visual acuity, intraocular pressure (IOP), anterior chamber inflammation, IOL position, and posterior synechiae. In addition, posterior segment evaluation and fundoscopy were performed. Intraoperative complication including posterior capsular rupture, anterior vitrectomy, and zonulysis as well as the site of IOL implantation were documented and post-operative complications including raised IOP, anterior chamber inflammation, visual axis opacity, posterior synechiae, subluxation of IOL, and IOL pigment deposition were listed.ResultsBest-corrected visual acuity 6 months after surgery was not different between the two groups. Also in early cataract surgery group, the rate of posterior capsular rupture was not significantly higher than the late surgery group (P=0.069). On the other hand, zonulysis was significantly higher in the late procedure group (P=0.039). Other complications including anterior vitrectomy, raised IOP, anterior chamber inflammation, visual axis opacity, posterior synechiae, subluxation of IOL, and IOL pigment deposition were not different in the two groups.ConclusionsEarly and late traumatic cataract surgery and IOL implantation after open globe injuries, have no significant difference regarding the post-surgical BCVA and prominent intraoperative and post-operative complications.

  10. Adjacent segment disease following cervical spine surgery.

    Cho, Samuel K; Riew, K Daniel

    2013-01-01

    Cervical spine surgery is broadly divided into fusion and nonfusion procedures. Anterior cervical diskectomy and fusion (ACDF) is a common procedure, although adjacent segment disease following the surgery is an ongoing clinical concern. Adjacent segment cervical disease occurs in approximately 3% of patients per year, with an expected incidence of 25% within the first 10 years following fusion. Nonfusion procedures such as anterior diskectomy and posterior foraminotomy do not decrease the rate of adjacent segment disease compared with ACDF. Recently, enthusiasm has developed for artificial disk replacement as a motion-sparing alternative to fusion. To date, however, multiple clinical trials and subsequent follow-up studies have failed to demonstrate significant reduction of adjacent segment disease when artificial disk replacement is performed instead of fusion.

A drawback of this technique is the possible instability of the anterior chamber caused by the sudden exit of air when the dye is injected with the cannula through the side-port incision. Other staining techniques that use viscoelastic substances to increase the stability of the anterior chamber and to dose the injected dye have been described. The authors present an under-air staining technique of the anterior capsule using one drop of Trypan blue injected with a 30 G needle through the peripheral cornea. This procedure prevents the air bubble from escaping the anterior chamber and allows fast and selective staining of the capsule.Keywords: Trypan blue, staining technique, dye, cataract surgery, capsulorhexis

    Anterior knee pain is the most common knee complaint. It may be due to a variety of soft tissue or osseous abnormalities. Knowledge of the radiologic appearance of the abnormalities allows more accurate diagnosis of the cause of the pain including chondral abnormalities, patellar instability and dislocation, femoral trochlear dysplasia, abnormal patellar location, bipartite patella, various tendinopathies, bursal inflammation, traction apophysitis in pediatric and adolescent patients, and miscellaneous diseases including mediopatellar plica syndrome and Hoffa's disease. Radiographs are often obtained to exclude acute osseous abnormalities, such as fractures. Magnetic resonance (MR) imaging offers superior soft tissue contrast resolution and allows for more accurate evaluation of the underlying etiology and therefore may improve treatment and possible surgical planning.

    To describe the initial outcomes following installation of a cataract surgery laser system. National Health Service cataract surgery day care unit in North London, UK. 158 eyes of 150 patients undergoing laser-assisted cataract surgery. Laser cataract surgery using the AMO Catalys femtosecond laser platform. intraoperative complications including anterior and posterior capsule tears. docking to the laser platform, successful treatment delivery, postoperative visual acuities. Mean case age was 67.7±10.8 years (range 29-88 years). Docking was successful in 94% (148/158 cases), and in 4% (6/148 cases) of these, the laser delivery was aborted part way during delivery due to patient movement. A total of 32 surgeons, of grades from junior trainee to consultant, performed the surgeries. Median case number per surgeon was 3 (range from 1-20). The anterior capsulotomy was complete in 99.3% of cases, there were no anterior capsule tears (0%). There were 3 cases with posterior capsule rupture requiring anterior vitrectomy, and 1 with zonular dialysis requiring anterior vitrectomy (4/148 eyes, 2.7%). These 4 cases were performed by trainee surgeons, and were either their first laser cataract surgery (2 surgeons) or their first and second laser cataract surgeries (1 surgeon). Despite the learning curve, docking and laser delivery were successfully performed in almost all cases, and surgical complication rates and visual outcomes were similar to those expected based on national data. Complications were predominately confined to trainee surgeons, and with the exception of intraoperative pupil constriction appeared unrelated to the laser-performed steps.

    To evaluate the influence of anterior chamber depth (ACD), anterior chamber volume (ACV), lens density (LD), and axial length (AL) as risk factors on endothelial cell loss 3 months after cataract surgery. We enrolled 47 patients with senile cataract who were operated between July 2012 and March 2013 by the same surgeon using torsional phacoemulsification. Preoperatively, we measured ACD, ACV, and LD using the Oculus Pentacam®. The AL was determined using the IOL Master®. Primary outcomes were central endothelial density (ECD) and corrected distance visual acuity (CDVA) 3 months after surgery We evaluated the effect of ACD, ACV, LD, and AL as possible risk factors of postoperative percentage endothelial cell loss (ECL). The median age was 72 years. The median CDVA before surgery was 0.5 improving to 1.0 postoperatively. The median ECL was 5.2 % (range 1.7 %-7.6 %). These results are comparable to our previous study (median ECL 6.9 % after 3 months) [Reuschel et al. (2010) J Cataract Refract Surg]. The median ACD in our study was 2.56 mm (range 2.26 mm-2.8 mm). Median ACV was 144 mm(3) (range 121 mm(3)-158 mm(3)]. The median LD was 12.4 (range 11.4-13.7). Median AL was 23.1 mm (range 22.7 mm-23.9 mm). Our correlation analysis showed no significant correlation between ACD, ACV, LD, AL, and postoperative ECL. ACD, ACV, AL, and LD were not identified as risk factors of postoperative endothelial cell loss in our analysis.

    Intramedullary nailing is the treatment of choice for the majority of tibial shaft fractures and anterior knee pain is the most common complication of this surgery; however, its etiology is still unknown. The purpose of this study was to assess the predicting factors related to anterior knee pain following tibial nailing. Patients with isolated, unilateral tibial shaft fracture who had undergone tibial nailing were identified retrospectively. Data including age, sex, type of fracture, technique of surgery and location of the nail were collected and finally the association between the above variables and knee pain were analyzed via SPSS software. A total of 95 patients participated in the study. The mean age of the participants was 33.52 ± 1.62, 87 (91.6%) of whom were male and 74 (77.9%) had close fractures respectively. The method of surgery in 60 (63.2%) patients was paratendinous approach and in 35 (36.8%) was transtendinous. Twenty six (27.4%) of the patients had anterior knee pain. There were no significant differences between the two groups of patients with and without knee pain by age, sex, type of fracture and type of surgery (P = 0.952, 0.502, 0.212 and 0.745, respectively). Patients with protrusion of the nail from the anterior cortex had higher risk of developing knee pain after surgery (odds ratio: 2.76, confidence interval: 1.08, 7.08, P = 0.031). The results revealed a higher risk of developing anterior knee pain after tibial nailing in patients with protrusion of the nail from the anterior cortex.

    Full Text Available The aim of the present study was to assess the presence and course of the anterior loop in the mental foramen region according to age and gender, using cone beam computed tomography (CBCT. Both the right and left sides were retrospectively studied in 141 patients (n = 282. Axial, sagittal, cross-sectional and panoramic images were evaluated and three-dimensional images were reconstructed and evaluated as necessary. The morphology, course and length of the anterior loop were measured. The reliability and reproducibility were assessed based on the intraclass correlation coefficient (ICC and the coefficient of variation. An anterior loop was found in about 86% of the scans. The mean anterior loop proximal edge was 3.15 mm and the mean distance between the buccal border of the anterior loop and buccal alveolar wall was 2.24 mm. The mean volume of the mandibular canal was 1140 mm3 and the mean volume of the anterior loop was 90 mm3. Statistically significant difference was found in male patients in terms of the canal and anterior loop volume (p < 0.05. A high prevalence of anterior loop was detected by CBCT imaging, with predominance in female patients. Clinicians should be careful during implant or bone surgery procedures to avoid possible complications, with special emphasis on patient age, using this imaging modality that involves use of less radiation.

  18. Analysis of low-energy and high-frequency femtosecond laser for the construction of deep anterior donor corneal lamellae

    2014-04-01

    Full Text Available Purpose: To evaluate the efficacy and reliability of a low-energy femtosecond laser with a high repetition rate for construction of deep anterior donor corneal lamellae. Methods: This was a prospective laboratory investigation. Twenty-five human corneal buttons were femtosecond laser cut to create thick anterior lamellae (diameter, 10mm; thickness, 500µm. The laser cuts were made using an LDV® femtosecond laser in a Ziemer® anterior chamber. To obtain a better edge, the lamellae were trephined with an 8mm trephine (Katena®. The central corneal thickness and the anterior lamellae were measured using a Mitutoyo® thickness gauge with an accuracy of 0.001mm. Results: The central thickness of the 25 corneas ranged from 500 to 705µm (mean, 584 ± 51µm. The thickness of the anterior lamellae ranged from 420 to 480µm (mean, 455 ± 12.7µm. The anterior lamellae diameters were 7.90 ± 0.1mm, and all laser cuts were round. The lamellar interfaces appeared regular by surgical microscopy. There were no cases of inter-lamellar adhesion. Conclusion: The LDV® femtosecond laser appears to be a safe and reliable instrument for cutting deep anterior lamellae from donor corneoscleral buttons. Minimal variation in donor lamellar depth with the laser will be useful for creating donor corneal tissue for deeper anterior lamellar keratoplasty or endothelial keratoplasty surgery or both from a single donor cornea.

    2018-02-01

    A prospective cohort of 142 patients underwent either anterior cervical discectomy alone, anterior cervical discectomy with fusion by cage stand-alone, or anterior cervical discectomy with arthroplasty. We then followed up on their condition for a mean of 9.1±1.9 years (5.6-12.2 y) later. We aimed to evaluate the annual rate of clinically symptomatic adjacent segment disease (ASD) and to analyze predictive factors. Until recent, ASD has been predominantly evaluated radiologically. It is not known whether all patients had complaints. A frequent cited annual rate of ASD is 2.9%, but a growing number of studies report a lower annual rate. Furthermore, maintaining motion to prevent ASD is one reason for implanting a cervical disk prosthesis. However, the results of studies contradict one another. Participants took part in a randomized controlled trial that ended prematurely because of the publication of evidence that did not justify continuation of the trial. The patients were randomly allocated to 3 groups, each of which received one of the abovementioned treatments. We defined symptomatic ASD as signs and symptoms caused by degeneration of an intervertebral disk adjacent to a level of previous anterior cervical disk surgery. At the last follow-up, we were able to ascertain whether clinically symptomatic ASD was present in any of the participants. The overall annual rate of symptomatic ASD was 0.7%. We found no statistically significant correlations between any of the investigated factors and symptomatic ASD except for the surgical method used. Symptomatic ASD was seen less often in anterior cervical discectomy solely or anterior cervical discectomy with arthroplasty than in anterior cervical discectomy with fusion by plate fixation. The annual rate of symptomatic ASD after an anterior cervical discectomy procedure was estimated to be 0.7%. This seems to be related to the procedure, although firm conclusions cannot be drawn.

    In treatment of anterior shoulder instability, many surgical techniques have been described, all of them with advantages and disadvantages. Our goal is to study the half term results on patients that underwent open Bristow-Latarjet surgery considering the preoperative ISIS value. This is a retrospective study of 33 patients which underwent open Bristow-Latarjet surgery in our center between 2005 and 2012. Average age of 33.2 years and follow up of 75 months. Results were taken by Rowe and Constant scores, DASH questionnaire and we also recorded a subjective assessment of the result by each patient. No recurrence was reported. No reoperations. Mean Rowe score was 74.6 points and mean Constant score was 70 points. In the disability questionnaire (DASH), the mean value was 22.9 points. The outcome assessment by the patients was positive in 78.8%. The migration of a screw occurred in one patient but he still asymptomatic. No other complication was identified. The Bristow-Latarjet technique is a reliable technique, with few complications and with an excellent rate of recurrence in treatment of chronic shoulder instability as reported in literature; it should be used as primary surgery in some cases and the preoperative ISIS score is an excellent and simple guide to select correctly the surgical technique for each patient.

    Relative young and more active patients with osteoarthritis (OA) of the isolated medial femorotibial compartment in conjunction with anterior cruciate ligament (ACL) deficiency are difficult to treat. The aim of this study was to explore the early clinical outcomes of combined Oxford unicompartmental knee arthroplasty (UKA) and ACL reconstruction for the patients presenting ACL deficiency and isolated OA of the medial compartment. Twenty-eight patients were included into the study. All patients were treated by combined Oxford UKA and ACL reconstruction. Plain radiographs in the antero-posterior and lateral view and long-leg standing radiographs were routinely performed prior to and after surgery. Stress radiographs in valgus were additionally available in order to verify the well-preserved lateral compartment. The varus deformity of the knee prior to surgery and the valgus degree after surgery, the posterior slope of the tibial component and the range of motion (ROM) of the knee after surgery were measured and recorded. Clinical evaluations include Oxford Knee Score (OKS), Knee Society Score (KSS-clinical score; KSS-function score) and Tegner activity score. All the patients were followed up for 52 ± 8 months. The leg alignment showed 3.1 ± 0.6° of varus deformity prior to surgery and 4.0 ± 0.7° of valgus after surgery. The OKS, KSS and Tegner activity score improved significantly after surgery (P < 0.05). The mean ROM of the operated knee was 123.5 ± 2.8° at the last follow-up. The posterior slope of the tibial component was 3.9 ± 1.2°. A significant correlation was found between them according to the Pearson's correlation (r = 0.39, P = 0.03). There were 2 patients (7 %) with the complication of mobile bearing dislocation, and a second operation of replacing a thicker mobile bearing was performed for them. The early clinical data have shown that combined surgery of UKA and ACL reconstruction has revealed promising

    Full Text Available The occurrence of de novo psychogenic seizures after epilepsy surgery is rare, and is estimated in 1.8% to 3.6%. Seizures after epilepsy surgery should be carefully evaluated, and de novo psychogenic seizures should be considered especially when there is a change in the ictal semiology. We report a patient with de novo psychogenic seizures after anterior temporal lobe removal for refractory temporal lobe epilepsy. Once psychogenic seizures were diagnosed and psychiatric treatment was started, seizures stopped.

    The extended transnasal approach, a recent surgical advancements for the ventral skull base, allows excellent midline access to and visibility of the anterior cranial fossa, which was previously thought to be approachable only via a transcranial route. The extended transnasal approach allows early decompression of the optic canals, obviates the need for brain retraction, and reduces neurovascular manipulation. Between 2004 and 2007, 11 consecutive patients underwent transnasal resection of anterior cranial fossa meningiomas--4 olfactory groove (OGM) and 7 tuberculum sellae (TSM) meningiomas. Age at surgery, sex, symptoms, and imaging studies were reviewed. Tumor size and tumor extension were estimated, and the anteroposterior, vertical, and horizontal diameters were measred on MR images. Medical records, surgical complications, and outcomes of the patients were collected. A gross-total removal of the lesion was achieved in 10 patients (91%), and in 1 patient with a TSM only a near-total (> 90%) resection was possible. Four patients with preoperative visual function defect had a complete recovery, whereas 3 patients experienced a transient worsening of vision, fully recovered within few days. In 3 patients (2 with TSMs and 1 with an OGM), a postoperative CSF leak occurred, requiring a endoscopic surgery for skull base defect repair. Another patient (a case involving a TSM) developed transient diabetes insipidus. The operative time ranged from 6 to 10 hours in the OGM group and from 4.5 to 9 hours in the TSM group. The mean duration of the hospital stay was 13.5 and 10 days in the OGM and TSM groups, respectively. Six patients (3 with OGMs and 3 with TSMs) required a blood transfusion. Surgery-related death occurred in 1 patient with TSM, in whom the tumor was successfully removed. The technique offers a minimally invasive route to the midline anterior skull base, allowing the surgeon to avoid using brain retraction and reducing manipulation of the large vessels and

  9. Atraumatic Anterior Dislocation of the Hip Joint

    2015-01-01

    Full Text Available Dislocation of the hip joint in adults is usually caused by high-energy trauma such as road traffic accidents or falls from heights. Posterior dislocation is observed in most cases. However, atraumatic anterior dislocation of the hip joint is extremely rare. We present a case of atraumatic anterior dislocation of the hip joint that was induced by an activity of daily living. The possible causes of this dislocation were anterior capsule insufficiency due to developmental dysplasia of the hip, posterior pelvic tilt following thoracolumbar kyphosis due to vertebral fracture, and acetabular anterior coverage changes by postural factor. Acetabular anterior coverage changes in the sagittal plane were measured using a tomosynthesis imaging system. This system was useful for elucidation of the dislocation mechanism in the present case.

    2016-05-01

    Anterior knee pain is one of the most common complications after total knee arthroplasty. An incidence of up to 30 % has been reported in peer-reviewed studies. The purpose of this study was to systematically review the literature and to identify determinants that have been analyzed with regard to anterior knee pain. Patient- and knee-specific characteristics, prosthetic designs and operative techniques are addressed as well as functional and neurologic determinants. Instability, increased contact pressure in the patellofemoral joint and patella maltracking due to malrotation of components, offset errors, ligament insufficiencies or patella baja are mechanical reasons for anterior knee pain. Functional causes include pathologic gait patterns, quadriceps imbalance and dynamic valgus. They have to be differentiated from infectious and inflammatory causes as well as soft tissue impingement, arthrofibrosis and neurologic diseases. A differentiated treatment algorithm is recommended. Often conservative treatment options exist, however, particularly with most mechanical causes revision surgery is necessary.

    Urothelial polyps arising from the anterior urethra are rarely encountered in the pediatric age group and are even rarer in the females. Scarcely reported in English literature, their exact incidence is not known. They may be asymptomatic for years or present with features of urinary obstruction, mass or "vaginal" bleeding. They are important in the differential diagnosis of interlabial masses in female children. Anterior urethral polyps are benign fibroepithelial lesions. Surgery is indicated for relief of symptoms and differentiation from malignant lesions such as a sarcoma or a papilloma. No recurrences have been reported. We report a case of solitary anterior urethral polyp in an 8-year old girl managed successfully at our centre. Copyright © 2012 Elsevier Inc. All rights reserved.

    Recurrent traumatic anterior shoulder dislocation results in soft tissues lesions around the glenohumeral joint. The subscapularis muscle is a major active stabilizer of the shoulder and the hypothesis of the current study is that one would expect pathologic changes within its substance secondary to the trauma. A histomorphometric study of the subscapularis muscle was done of 52 patients operated on for recurrent traumatic anterior shoulder dislocation. At the time of surgery biopsy specimens were taken of the subscapularis muscle and the ipsilateral deltoid muscle as a comparison and to see if any changes were present. The results revealed interstitial fibrosis within the subscapularis muscle compatible with muscle scarring, and modifications in the ratio of fiber types as usually is seen with disuse atrophy. Both of these findings may alter strength and stability and therefore the function of the glenohumeral joint. The histologic findings were not compatible with a denervation pattern. After traumatic anterior shoulder dislocation rehabilitation of the subscapularis muscle is recommended.

  13. BONE TUNNEL WIDENING AFTER ANTERIOR CRUCIATE LIGAMENT AUTOPLASTY WITH HAMSTRINGS (LITERATURE REVIEW

    2017-01-01

    Full Text Available ABSTRACT Such a phenomenon as bone tunnel widening after anterior cruciate ligament autoplasty with hamstrings has been known for 30 years. Despite the long history of this issue, the etiology is still not fully understood. The process of expansion of the bone tunnels is influenced by many factors such as graft fixation technique, surgical technique and rehabilitation protocol, as well as various biological factors. It is believed that this phenomenon has no influence on a functional result, but may create serious problems in revision anterior cruciate ligament surgery. Given the growing interest in the use of hamstring tendon grafts for anterior cruciate ligament reconstruction, increasing number of these operations and as a result, of revision procedures, the search for methods of bone tunnel widening prevention is becoming more urgent.

  14. Anterior Abdominal Wall Leiomyoma Arising De Novo in a Perimenopausal Woman

    2012-07-01

    Full Text Available Extrauterine or extraintestinal leiomyomas are extremely uncommon especially in the pre-peritoneal area or within the anterior abdominal wall muscles. These tumors have been ascribed to intraoperative seeding during resection of a fibroid or a leiomyoma of gut, to exogenous hormone replacement therapy or a major derangement of glucose and/or lipid metabolism. So far, there is no published report of de novo origin of anterior abdominal wall pure leiomyoma in the literature. The author herein reports a case of perimenopausal multiparous woman without any listing of previous gynecological surgery or hormone therapy who presented with a large pre-peritoneal intramuscular leiomyoma of the anterior abdominal wall. The patient underwent complete primary resection with amelioration of her symptoms.

    Ankle joint fracture is one of the most common types of fracture. There are many researches on the injury mechanism, treatment principles and surgical techniques. A type of injury which combines posterior dislocation of fibula, known as the Bosworth injury, is relatively rare. In 1947, Bosworth first described this type of injury as an unusual ankle fracture dislocation with fixed posterior fracture dislocation of the distal part of the fibula. In this type of fracture, the proximal fibular shaft fragment locks behind the tibialis posterior tubercle. This rare ankle fracture variant is often not recognized in initial radiographs and requires a computed tomographic (CT) scan for verification. But there are already many reports, discussing the injury mechanism, treatment principles and surgical techniques. However, there are few reports of anterior dislocation of the fibula, caused by either injury or surgery. The mechanism of the injury is still not clear. This article reports a case of anterior dislocation of the fibula. We report a patient with left ankle open fracture (Lauge-Hansen pronation-external rotation stage III, Gustilo IIIA). Open reduction and internal fixation was done in the initial surgery, but ended up with poor reduction, resulting in fibula anterior dislocation, anterior dislocation of talus and tibia fibular dislocation. The fibula was dislocated anteriorly of the tibia, which rarely happened. The patient suffered severe ankle joint dysfunction. The second operation took out the original internal fixation, reduced the fracture, and reset the internal fixation. The function of ankle joint was improved obviously after operation. But because of the initial injury and the two operations, the soft tissue around the fracture was greatly damaged. 6 months after the second operation, and the fracture still not healed, so the bone graft was carried out in the third surgery. Two months after the third surgery, the function of the ankle was significantly

    We report a case of an intractable fistula repaired by transsacral direct suture. A 65-year-old man underwent low anterior resection for rectal cancer. He subsequently underwent ileostomy due to anastomosis leakage. The fistula of the anastomosis persisted 3 months after surgery. He underwent surgery to repair the fistula using a transsacral approach. After removing the coccyx, the fistula in the postrectal space was exposed directly. The presence of the fistula was confirmed by an air leak test and was closed by direct suture. After 33 days, the patient underwent ileostomy closure.

    Context: Anterior cruciate ligament (ACL) reconstruction rehabilitation has evolved over the past 20 years. This evolution has been driven by a variety of level 1 and level 2 studies. Evidence Acquisition: The MOON Group is a collection of orthopaedic surgeons who have developed a prospective longitudinal cohort of the ACL reconstruction patients. To standardize the management of these patients, we developed, in conjunction with our physical therapy committee, an evidence-based rehabilitation guideline. Study Design: Clinical review. Level of Evidence: Level 2. Results: This review was based on 2 systematic reviews of level 1 and level 2 studies. Recently, the guideline was updated by a new review. Continuous passive motion did not improve ultimate motion. Early weightbearing decreases patellofemoral pain. Postoperative rehabilitative bracing did not improve swelling, pain range of motion, or safety. Open chain quadriceps activity can begin at 6 weeks. Conclusion: High-level evidence exists to determine appropriate ACL rehabilitation guidelines. Utilizing this protocol follows the best available evidence. PMID:26131301

    Purpose. To evaluate the anatomic effects of phacoemulsification on drainage angle status in primary angle closure glaucoma (PACG) using anterior segment optical coherence tomography (AS-OCT). Methods. A total of 62 eyes of 58 patients underwent cataract surgery in Farabi Rye Hospital, Tehran, Iran. Patients were examined postoperatively on day 1, week 1, and week 6. Indentation gonioscopy and AS-OCT were performed preoperatively and at 6 weeks after surgery. Main outcome measures were angle and anterior segment parameters by AS-OCT and amount of peripheral anterior synechiae (PAS) by gonioscopy. Thirty-five eyes had PAS =180 degrees (group 1) and 27 eyes had >180-degree synechial closure (group 2). Results. Mean age of the patients was 64.3±9.0 years. The mean extent of PAS was significantly reduced from 45.9 to 32.2 degrees (p180 degrees.

    Full Text Available Abstract Background In idiopathic scoliosis patients, after anterior spinal fusion and instrumentation, the discs (interspace angle between the lowest instrumented vertebra (LIV and the next caudal vertebra became more wedged. We reviewed these patients and analyzed the changes of the angle. Methods By reviewing the medical records and roentgenograms of adolescent idiopathic scoliosis patients underwent anterior spinal fusion and instrumentation, Cobb angle of the curve, correction rate, coronal balance, LIV rotation, interspace angle were measured and analyzed. Results There were total 30 patients included. The mean coronal Cobb angle of the main curve (thoracolumbar/lumbar curve before and after surgery were 48.9° and 11.7°, respectively, with an average correction rate of 76.1%. The average rotation of LIV before surgery was 2.1 degree, and was improved to 1.2 degree after surgery. The interspace angle before surgery, on convex side-bending films, after surgery, at final follow up were 3.2°, -2.3°, 1.8° and 4.9°, respectively. The difference between the interspace angle after surgery and that preoperatively was not significant (P = 0.261, while the interspace angle at final follow-up became larger than that after surgery, and the difference was significant(P = 0.012. The interspace angle after surgery was correlated with that on convex side-bending films (r = 0.418, P = 0.022, and the interspace angle at final follow-up was correlated with that after surgery (r = 0.625, P = 0.000. There was significant correlation between the loss of the interspace angle and the loss of coronal Cobb angle of the main curve during follow-up(r = 0.483, P = 0.007. Conclusion The interspace angle could be improved after anterior correction and instrumentation surgery, but it became larger during follow-up. The loss of the interspace angle was correlated with the loss of coronal Cobb angle of the main curve during follow-up.

    Abstract Background Injury to the anterior cruciate ligament (ACL) of the knee is common. Following complete rupture of the ACL, insufficient re-vascularization of the ligament prevents it from healing completely, creating a need for reconstruction. A variety of grafts are available for use in ACL reconstruction surgery, including synthetic grafts. Over the last two decades new types of synthetic ligaments have been developed. One of these synthetic ligaments, the Ligament Advanced Reinforcem...

    Outcomes for rectal cancer surgery have improved significantly over the past 20 years with increasing rates of survival and recurrence, specifically local recurrence. These gains have been realized during a period of time in which there has been an increasing emphasis on sphincter preservation. As we have become increasingly aggressive in avoiding resection of the anus, we have begun accepting bowel dysfunction as a normal outcome. Low anterior resection syndrome, defined as a constellation of symptoms including incontinence, frequency, urgency, or feelings of incomplete emptying, has a significant impact on quality of life and results in many patients opting for a permanent colostomy to avoid these symptoms. In this article, we will highlight the most recent clinical and basic science research on this topic and discuss areas of future investigation.

    2016-06-01

    Full Text Available A 19-year-old male subject was diagnosed with medial meniscal, lateral meniscal and anterior cruciate ligament (ACL tear. The symptoms did not subside after 4 months of physical therapy, and he underwent arthroscopic partial medial and lateral meniscectomy and ACL reconstruction. Immediately after the patient woke up from general anesthesia, he started experience loss of sensation in the area of superficial peroneal nerve with inverted dorsiflexion of foot and ankle. Instantly, the bandage and knee brace was removed and a diagnosis of compartment syndrome was ruled out. After eight hours, post-operatively, the patient started receiving physiotherapy. He complained of numbness and tingling in the same area. After 24 h, post-operatively, the patient started to regain dorsiflexion and eversion gradually. Two days after the surgery, the patient exhibited complete recovery of neurological status.

    Unruptured anterior inferior cerebellar artery (AICA) aneurysms are rare but potentially lethal cerebellopontine angle (CPA) lesions that may be misdiagnosed as vestibular schwannomas when they present with vestibulo-cochlear symptoms. We report two cases of unruptured but symptomatic AICA aneurysms initially referred to us as atypical vestibular schwannomas requiring surgery. Two discriminant MR features are described. One patient refused treatment. The other was successfully treated by coil occlusion. Caution is advised before suspecting a CPA mass to be a purely extra-canalicular schwannoma, given its extreme rarity. Deafness and cerebellar ischemia may be prevented if AICA aneurysms are correctly identified preoperatively. In the absence of specific arterial imaging, two MR features may distinguish them from vestibular schwannomas: (1) the absence of internal auditory canal enlargement and (2) the "blurry dot sign," representing blood flow artefacts on pre- and postcontrast studies.

    Full Text Available Objective: We describe a novel spatula and dissector to facilitate the big-bubble technique in deep anterior lamellar keratoplasty (DALK. Methods: A 29-year-old man who was diagnosed with bilateral keratoconus underwent deep anterior lamellar keratoplasty (DALK. After 350μm partial thickness incision of the recipient cornea, the Bonfadini dissector was inserted at the deepest point in the peripheral incision and could be advanced to the center of the cornea safely because of its "semi-sharp" tip. After achieving the big-bubble (BB separation of Descemet membrane (DM from the overlying stroma, the anterior stromal disc was removed. Viscoelastic material was placed on the stromal bed to prevent uncontrolled collapse and perforation of DM during the paracentesis blade incision into the BB. We could detect the safe opening of the BB using the Bonfadini dissector by the leakage of air bubbles into the viscoelastic material. After injecting viscoelastic material into the BB space, we inserted the Bonfadini spatula into the bigbubble safely because of its curved profile and blunt edges. The groove along the length of the Bonfadini spatula enables safe and efficient incision or the residual stromal tissue using the pointed end of a sharp blade while protecting the underlying DM. After removal of posterior stroma, the donor button was sutured with 16 interrupted 10-0 nylon sutures. Results: This technique and the use of the Bonfadini spatula and dissector facilitate exposure of Descemet membrane. Conclusion: The smooth Bonfadini DALK spatula and dissector facilitate safe and efficient completion of DALK surgery.

  10. Anterior and nasal transposition of the inferior oblique muscles.

    2003-06-01

    When performing anterior transposition of the inferior oblique (IO) muscle, placement of the posterior suture close to the lateral border of insertion of the inferior rectus (IR) muscle decreases the incidence of antielevation syndrome (AES). We hypothesized that placement of the suture nasal to the IR muscle insertion will convert the IO muscle into an intorter and depressor. Here we present the first series of results obtained with a new procedure for the treatment of elevation in adduction with extorsion and abnormal head postures. Twenty patients with IO muscle overaction, superior oblique (SO) muscle palsy, absent SO muscles, AES, or Duane syndrome were studied. Before surgery, each patient showed at least one, but often more, of the following signs: elevation in adduction, exotropia (XT) in up gaze, abnormal head posture, and extorsion. Each underwent anterior and nasal transposition (ANT) of the IO muscle, with the new insertion typically 2 mm nasal and 2 mm posterior to the nasal border of the IR muscle insertion. Large improvements in ocular alignment, extorsion, and head posture were found in most patients. However, a poor result was noted in a patient with Y-pattern XT, who developed a mild amount of comitant XT after an extreme degree of ANT (4 mm nasal and 3 mm anterior to the nasal border of the IR muscle insertion). In Duane syndrome, ANT corrects upshoot, but downshoot may get worse. Mersilene permanent sutures, rather than dissolving suture materials, are recommended to avoid postoperative retraction of muscle fibers. ANT converts the IO muscle into an intorter and tonic depressor and can significantly improve elevation in adduction. This procedure seems particularly useful in patients with severe or recurrent congenital and acquired SO palsies, particularly as a secondary procedure. Extreme ANT may induce exotropia in the primary position.

    A multicenter retrospective case series. Horner's syndrome is a known complication of anterior cervical spinal surgery, but it is rarely encountered in clinical practice. To better understand the incidence, risks, and neurologic outcomes associated with Horner's syndrome, a multicenter study was performed to review a large collective experience with this rare complication. We conducted a retrospective multicenter case series study involving 21 high-volume surgical centers from the AOSpine North America Clinical Research Network. Medical records for 17 625 patients who received subaxial cervical spine surgery from 2005 to 2011 were reviewed to identify occurrence of 21 predefined treatment complications. Descriptive statistics were provided for baseline patient characteristics. Paired t test was used to analyze changes in clinical outcomes at follow-up compared to preoperative status. In total, 8887 patients who underwent anterior cervical spine surgery at the participating institutions were screened. Postoperative Horner's syndrome was identified in 5 (0.06%) patients. All patients experienced the complication following anterior cervical discectomy and fusion. The sympathetic trunk appeared to be more vulnerable when operating on midcervical levels (C5, C6), and most patients experienced at least a partial recovery without further treatment. This collective experience suggests that Horner's syndrome is an exceedingly rare complication following anterior cervical spine surgery. Injury to the sympathetic trunk may be limited by maintaining a midline surgical trajectory when possible, and performing careful dissection and retraction of the longus colli muscle when lateral exposure is necessary, especially at caudal cervical levels.

    Materials were 26 malignant anterior mediastinal tumors: 7 thymic carcinomas, 6 invasive thymomas, 7 malignant lymphomas (ML) and 6 malignant germ cell tumors (GCT). Egg shell calcification in the tumor was indicative of the invasive thymoma. Presence of conglomerated mass in the anterior mediastinum strongly suggested the diagnosis of ML. Although differentiation between thymic carcinoma and ML was difficult, punctate calcification and pleural implants were frequently found in the former. GCT showed no significant findings on CT. However, another clinical information was helpful to make correct diagnosis. CT guided biopsy is necessary to diagnose the malignant anterior mediastinal tumors. (author)

    Bowel anastomosis after anterior resection is one of the most difficult tasks to perform during laparoscopic colorectal surgery. This study aims to evaluate a new feasible and safe intracorporeal anastomosis technique after laparoscopic left-sided colon or rectum resection in a pig model. The technique was evaluated in 5 pigs. The OrVil device (Covidien, Mansfield, Massachusetts) was inserted into the anus and advanced proximally to the rectum. A 0.5-cm incision was made in the sigmoid colon, and the 2 sutures attached to its delivery tube were cut. After the delivery tube was evacuated through the anus, the tip of the anvil was removed through the perforation. The sigmoid colon was transected just distal to the perforation with an endoscopic linear stapler. The rectosigmoid segment to be resected was removed through the anus with a grasper, and distal transection was performed. A 25-mm circular stapler was inserted and combined with the anvil, and end-to-side intracorporeal anastomosis was then performed. We performed the technique in 5 pigs. Anastomosis required an average of 12 minutes. We observed that the proximal and distal donuts were completely removed in all pigs. No anastomotic air leakage was observed in any of the animals. This study shows the efficacy and safety of intracorporeal anastomosis with the OrVil device after laparoscopic anterior resection.

    Results of the surgical reconstruction of the anterior cruciate ligament (ACL), using as a graft fourfold hamstring tendons (gracilis and semitendinosus) and middle third of the patellar ligament, were compared. In all patients that were participating in this study clinical examination and magnetic resonance showed ACL rupture, and apart from the choice of the graft, surgical technique was identical. We evaluated 112 patients with implemented patellar ligament graft and fourfold hamstring tendons graft six months after the procedure. Both groups were similar according to age, sex, activity level, knee instability level and rehabilitation program. The results showed that there was no significant difference between groups regarding Lysholm Knee score, IKDC 2000 score, activity level, musculature hypotrophy, and knee joint stability 6 months after the surgery. Anterior knee pain incidence is significantly higher in the group with patellar ligament graft (44% vs. 21%). Both groups had a significant musculature hypotrophy of the upper leg of the knee joint that was surgically treated, six months after the procedure. Both grafts showed good subjective and objective results.

  17. Sellar plasmacytoma presenting with symptoms of anterior pituitary dysfunction

    2017-11-01

    Full Text Available Sellar plasmacytomas are rare and the differential diagnosis with non-functioning pituitary adenomas might be difficult because of clinical and radiological resemblance. They usually present with neurological signs and intact anterior pituitary function. Some may already have or eventually progress to multiple myeloma. We describe a case associated with extensive anterior pituitary involvement, which is a rare form of presentation. A 68-year-old man was referred to our Endocrinology outpatient clinic due to gynecomastia, reduced libido and sexual impotence. Physical examination, breast ultrasound and mammography confirmed bilateral gynecomastia. Blood tests revealed slight hyperprolactinemia, low testosterone levels, low cortisol levels and central hypothyroidism. Sellar MRI showed a heterogeneous sellar mass (56 × 60 × 61 mm, initially suspected as an invasive macroadenoma. After correcting the pituitary deficits with hydrocortisone and levothyroxine, the patient underwent transsphenoidal surgery. Histological examination revealed a plasmacytoma and multiple myeloma was ruled out. The patient was unsuccessfully treated with radiation therapy (no tumor shrinkage. Myeloma ultimately developed, with several other similar lesions in different locations. The patient was started on chemotherapy, had a bone marrow transplant and is now stable (progression free on lenalidomide and dexamethasone. The presenting symptoms and panhypopituitarism persisted, requiring chronic replacement treatment with levothyroxine, hydrocortisone and testosterone.

    2014-01-01

    Context: Reconstruction of the anterior cruciate ligament (ACL) is one of the most common surgical procedures, with more than 200,000 ACL tears occurring annually. Although primary ACL reconstruction is a successful operation, success rates still range from 75% to 97%. Consequently, several thousand revision ACL reconstructions are performed annually and are unfortunately associated with inferior clinical outcomes when compared with primary reconstructions. Evidence Acquisition: Data were obtained from peer-reviewed literature through a search of the PubMed database (1988-2013) as well as from textbook chapters and surgical technique papers. Study Design: Clinical review. Level of Evidence: Level 4. Results: The clinical outcomes after revision ACL reconstruction are largely based on level IV case series. Much of the existing literature is heterogenous with regard to patient populations, primary and revision surgical techniques, concomitant ligamentous injuries, and additional procedures performed at the time of the revision, which limits generalizability. Nevertheless, there is a general consensus that the outcomes for revision ACL reconstruction are inferior to primary reconstruction. Conclusion: Excellent results can be achieved with regard to graft stability, return to play, and functional knee instability but are generally inferior to primary ACL reconstruction. A staged approach with autograft reconstruction is recommended in any circumstance in which a single-stage approach results in suboptimal graft selection, tunnel position, graft fixation, or biological milieu for tendon-bone healing. Strength-of-Recommendation Taxonomy (SORT): Good results may still be achieved with regard to graft stability, return to play, and functional knee instability, but results are generally inferior to primary ACL reconstruction: Level B.

    The surgical management of shoulder instability is an expanding and increasingly complex area of study within orthopaedics. This article describes the history and evolution of shoulder instability surgery, examining the development of its key principles, the currently accepted concepts and available surgical interventions. A comprehensive review of the available literature was performed using PubMed. The reference lists of reviewed articles were also scrutinised to ensure relevant information was included. The various types of shoulder instability including anterior, posterior and multidirectional instability are discussed, focussing on the history of surgical management of these topics, the current concepts and the results of available surgical interventions. The last century has seen important advancements in the understanding and treatment of shoulder instability. The transition from open to arthroscopic surgery has allowed the discovery of previously unrecognised pathologic entities and facilitated techniques to treat these. Nevertheless, open surgery still produces comparable results in the treatment of many instability-related conditions and is often required in complex or revision cases, particularly in the presence of bone loss. More high-quality research is required to better understand and characterise this spectrum of conditions so that successful evidence-based management algorithms can be developed. IV.

  20. Ectopic thyroid mass in the left lateral neck and anterior mediastinum: a case report

    Science.gov (United States)

    2014-01-01

    Introduction Ectopic thyroid is characterized by the presence of thyroid tissue in a site other than in its usual pretracheal region. It is a rare condition among the thyroid diseases. Dural ectopic thyroid present in the cervical and anterior mediastinal has not been reported. Case presentation A 45-year-old Chinese woman presented with a nonfunctional ectopic thyroid located both in the cervical and anterior mediastinum. The ectopic thyroid was removed under video-assisted thoracoscopic surgery using a transverse neck incision and her postoperative period has been uneventful thus far. Conclusions Ectopic thyroid is a rare condition among the thyroid diseases, and its location in the anterior mediastinum is even more uncommon. Less than 15 cases have been reported in the last four decades. This is the first case of ectopic thyroid to appear in both the cervical and anterior mediastinum at same time. Masses in the anterior mediastinal are usually thymoma, lymphoma, pheochromocytoma and germ cell tumors. Ectopic thyroid in this area is quite rare so this case enhances our understanding of the diagnosis of mediastinal masses. PMID:25335650

    This study aims to retain normal knee kinematics after knee replacement surgeries by reconstructing anterior cruciate ligament during total knee arthroplasty. We use computational simulation tools to establish four dynamic knee models, including normal knee model, posterior cruciate ligament retaining knee model, posterior cruciate ligament substituting knee model, and anterior cruciate ligament reconstructing knee model. Our proposed method utilizes magnetic resonance images to reconstruct solid bones and attachments of ligaments, and assemble femoral and tibial components according representative literatures and operational specifications. Dynamic data of axial tibial rotation and femoral translation from full-extension to 135 were measured for analyzing the motion of knee models. The computational simulation results show that comparing with the posterior cruciate ligament retained knee model and the posterior cruciate ligament substituted knee model, reconstructing anterior cruciate ligament improves the posterior movement of the lateral condyle, medial condyle and tibial internal rotation through a full range of flexion. The maximum posterior translations of the lateral condyle, medial condyle and tibial internal rotation of the anterior cruciate ligament reconstructed knee are 15.3 mm, 4.6 mm and 20.6 at 135 of flexion. Reconstructing anterior cruciate ligament in total knee arthroplasty has been approved to be an more efficient way of maintaining normal knee kinematics comparing to posterior cruciate ligament retained and posterior cruciate ligament substituted total knee arthroplasty.

    The use of implants for the restoration of anterior missing teeth has been established and documented during the past years. However, the use of dental implants in the anterior region is a technique-sensitive procedure. The placement of implants in an ideal position is often not possible because of the lack of sufficient bone. The clinical situation can be further complicated if the teeth were lost as a result of trauma and there is possible damage to the surrounding soft and hard tissues. The restoration of lost anterior teeth and maintenance of the surrounding soft tissues with adequate surgical and prosthetic techniques are a real challenge for the clinician. The aim of this article was to report the laboratory and clinical stages in the restoration of anterior maxillary teeth, which were lost as a result of trauma with implant-supported fixed partial denture. In this case, an intraoperative transfer of the impression posts allowed the construction of provisional restorations, which were inserted at implant uncoverage surgery and contributed significantly to the creation of a better emergence profile and to the final esthetic result. Provisional restorations are an important stage in anterior maxillary implants, allowing guided soft tissue management and creating an esthetic emergence profile.

    The anterior root of the lateral meniscus (LM) dives underneath the tibial attachment of the anterior cruciate ligament (ACL). Although the distinct role of meniscal attachments has been investigated, the relationship between the LM anterior insertion (LMAI) and ACL tibial insertion (ACLTI) remains unclear. This study histologically analyzed the LMAI and ACLTI. Samples were divided into four regions in an anterior-to-posterior direction. Histological measurements of these insertion sites were performed using safranin O-stained coronal sections. Distribution and signal densities of type I and II collagen were quantified. The ACLTI and LMAI formed the ACL-LM complex via fiber connections. The anterior part of the ACLTI had a widespread attachment composed of dense fibers. Attachment fibers of the LMAI became dense and wide gradually at the middle-to-posterior region. The ACL-LM transition zone (ALTZ) was observed between the LMAI and the lateral border of the ACLTI at the middle part of the ACL tibial footprint. Type II collagen density of the LMAI was higher than that of the ACLTI and ALTZ. Our results can help create an accurate tibial bone tunnel within the dense ACL attachment during ACL reconstruction surgery.

    To report histopathologic findings in a case of bilateral corneal ectasia following intrastromal femtosecond laser presbyopia surgery. Case report. A 56-year-old patient was referred for bilateral corneal ectasia. He was treated for hyperopia using LASIK twice in both eyes. A bilateral femtosecond laser intrastromal presbyopia correction was secondarily performed. The patient complained of progressive loss of distance visual acuity shortly after. Corneal topography showed a bilateral central corneal protrusion. Rigid contact lenses were successfully fitted on the right eye and, because the patient still complained, a deep anterior lamellar keratoplasty was performed in the left eye. Light and electronic microscopy of the corneal button revealed that the inner intrastromal incision crossed the LASIK interface and led to stromal bed dehiscence. This case illustrates that intrastromal refractive surgery should not be recommended in eyes previously treated by lamellar refractive surgery.

    Torsional deformities of the femur and/or tibia often go unrecognized in adolescents and adults who present with anterior knee pain, and patellar maltracking or instability. While open and arthroscopic surgical techniques have evolved to address these problems, unrecognized torsion may compromise the outcomes of these procedures. We collected a group of 16 consecutive patients (23 knees), with mean age of 17, who had undergone knee surgery before torsion was recognized and subsequently treate...

    The purpose of this study was to evaluate the prevalence of anterior knee pain in anatomic double-bundle anterior cruciate ligament (ACL) reconstruction and to identify critical factors affecting postoperative anterior knee pain development. Subjects comprised 171 patients (171 knees) who underwent anatomic double-bundle ACL reconstruction with a follow-up period of ≥2 years. The procedure used bone-patellar tendon-bone plus gracilis tendon (BTB-G) in 56 knees, semitendinosus tendon (ST) in 71 knees, and ST-G in 44 knees. Clinical results and prevalence and severity of anterior knee pain were assessed at 3 months and 2 years postoperatively. Clinical variables influencing anterior knee pain development at each postoperative period were subjected to univariate analysis, followed by logistic regression analysis to identify risk factors for anterior knee pain. Overall prevalences of anterior knee pain at 3 months and 2 years postoperatively were 42.0 and 11.1%, respectively. Use of BTB-G graft represented the highest prevalence of anterior knee pain between the 3 different grafts (P = 0.001); however, this statistical significance disappeared at 2 years postoperatively. Prevalence of postoperative extension deficit was significantly higher in anterior knee pain-positive cohort than in anterior knee pain-negative cohort at 3 months postoperatively. Level of quadriceps strength was significantly lower, and Lysholm score was significantly worse in anterior knee pain-positive cohort than in anterior knee pain-negative cohort at 2 years postoperatively. According to logistic regression analysis, knee extension deficit was a predisposing factor for the development of anterior knee pain at 3 months postoperatively (odds ratio, 2.76; P = 0.004); however, there was no significant predisposing factor for anterior knee pain at 2 years postoperatively. Knee extension deficit was an important predisposing factor for postoperative anterior knee pain in the early

    Ruptures of the tibialis anterior tendon are rare. We present the clinical histories and MRI findings of three recent male patients with tibialis anterior tendon rupture aged 58-67 years, all of whom presented with pain over the dorsum of the ankle. Two of the three patients presented with complete rupture showing discontinuity of the tendon, thickening of the retracted portion of the tendon, and excess fluid in the tendon sheath. One patient demonstrated a partial tear showing an attenuated tendon with increased surrounding fluid. Although rupture of the tibialis anterior tendon is a rarely reported entity, MRI is a useful modality in the definitive detection and characterization of tibialis anterior tendon ruptures. (orig.)

    at the level of ACR were not statistically significant. Total visual analog score, Oswestry Disability Index, and Scoliosis Research Society-22 scores all improved from preoperative to postoperative and preoperative to 1-year follow-up. Fourteen patients (35.9%) experienced 26 complications (15 major and 11 minor). Eleven patients required reoperation. The most common complication was proximal junctional kyphosis (6/26 complications, 23%) followed by vertebral body/endplate fracture (3/26, 12%). CONCLUSIONS This study showed satisfactory radiographic and clinical outcomes at the 1-year follow-up. Proximal junctional kyphosis was the most common complication followed by fracture, complications that are commonly associated with sagittal realignment surgery and may not be mitigated by the anterior approach.

    We aimed to investigate factors related to the prevalence of anterior disc displacement without reduction (ADDwoR) and bony changes of the condylar head (bony changes) in the temporomandibular joints (TMJs) of patients with anterior open bite. Subjects are comprised of 36 preoperative patients (72 joints) with skeletal anterior open bite without facial asymmetry who had undergone orthognathic surgery at the Hokkaido University Hospital; magnetic resonance imaging of the TMJ and cephalometric analysis were performed before treatment. Logistic regression analysis was performed to clarify relationships among age, overbite, overjet, ANB angle, sella to nasion (SN) to mandibular plane angle (SN-MP angle), SN to ramus plane angle (GZN angle), gonial angle, and incidence of ADDwoR or bony changes in patients with anterior open bite. Fifteen patients had bilateral ADDwoR, and five patients had unilateral ADDwoR; 17 patients had bilateral bony changes, and five patients had unilateral bony changes. SN-MP angle was greater in 20 patients with ADDwoR than that in 16 patients without ADDwoR (p < 0.05). GZN angle was greater in the 20 patients showing bony changes than that in the 16 patients without bony changes (p < 0.05). In terms of dentofacial morphology, SN-MP angle appears to be associated with the incidence of ADDwoR, and GZN angle appears to be associated with bony changes in the TMJ.

    Full Text Available Abstract Recent years have seen ACL reconstruction performed in a broad range of patients, regardless of age, sex or occupation, thanks to great advances in surgical techniques, instrumentation and the basic research. Favorable results have been reported; however, we have not been able to locate any reports describing ACL reconstruction in patients with athetoid cerebral palsy. We present herein a previously unreported anterior cruciate ligament (ACL reconstruction performed in a patient with athetoid cerebral palsy. The patient was a 25-year-old woman with level II athetoid cerebral palsy according to the Gross Motor Function Classification System. She initially injured her right knee after falling off a bicycle. Two years later, she again experienced right-knee pain and a feeling of instability. A right-knee ACL tear and avulsion fracture was diagnosed upon physical examination and confirmed with magnetic resonance imaging (MRI and X-ray examination at that time. An ACL reconstruction using an autologous hamstring double-bundle graft was performed for recurrent instability nine years after the initial injury. Cast immobilization was provided for 3 weeks following surgery and knee extension was restricted for 3 months with the functional ACL brace to prevent hyperextension due to involuntary movement. Partial weight-bearing was started 1 week postoperatively, with full weight-bearing after 4 weeks. The anterior drawer stress radiography showed a 63% anterior displacement of the involved tibia on the femur six months following the surgery, while the contralateral knee demonstrated a 60% anterior displacement of the tibia. The functional ACL functional brace was then removed. A second-look arthroscopy was performed 13 months after the ACL reconstruction, and both the anteromedial and posterolateral bundles were in excellent position as per Kondo’s criteria. The Lachman and pivot shift test performed under anesthesia were also negative. An

Of these, 11 were interviewed...... and many patients said that they joined the RCT in order to bypass waiting lists. Patients who chose to cross-over described training as time consuming, boring and as unable to provide sufficient results within a reasonable timeframe.

    New imaging technologies are revolutionizing the understanding and treatment of a wide variety of ocular disorders. Confocal scanning laser ophthalmoscopy, ultrasound biomicroscopy, confocal scanning laser polarimetry, color doppler imaging of blood flow, and optical coherence tomography are providing important information regarding disease pathophysiology, diagnosis, progression, and treatment. High frequency (50 MHz), high resolution ultrasound biomicroscopy of the anterior segment was obtained in a wide variety of disorders of the anterior segment. Tissue resolution is approximately 50 microns and the penetration depth is 5 mm. Ultrasound biomicroscopy is capable of imaging the comea, iris, anterior chamber, anterior chamber angle, posterior chamber, and ciliary body with great detail. The structures surrounding the posterior chamber, previously hidden from clinical observation, can be imaged and their normal anatomic relationships assessed. The various forms of angle closure glaucoma, such as pupillary block and plateau iris configuration, can be differentiated. The concave iris found in pigment dispersion and its response to treatment can be assessed. Visualization of anterior segment anatomy in eyes with opaque media is possible. Ultrasound biomicroscopy assists in the management of eyes with disorders of the anterior segment. Future applications of this technology will yield important information regarding accommodation, normal ocular physiology and disease pathophysiology.

  16. Anterior double plating for rigid fixation of isolated tibiotalar arthrodesis.

    Arthrodesis is the most common procedure used to treat end-stage osteoarthritis of the ankle, particularly in patients with difficult conditions such as poor bone quality. While many techniques are available to fuse the ankle, current recommendations favor the use of internal fixation with screws and/or plates. Despite of progress, the complication rate remains a major concern. Non-union is one difficult problem especially with difficult bone conditions, particularly the loss of bone stock on the talar side. Therefore, fusion of the tibiotalar joint is often extended to the talocalcaneal joint to provide sufficient stability. To preserve the subtalar joint, an anterior double plate system for rigid fixation of isolated tibiotalar arthrodesis was developed. This is a preliminary report on the clinical and radiological outcome with this technique. Twenty-nine patients (15 men, 14 women; one ankle per patient) were treated from October 2006 to September 2007. We converted 16 ankles with osteoarthritis and difficult bone conditions, four non-united ankle arthrodeses, and nine failed total ankle replacements to an isolated tibiotalar arthrodesis using anterior double plating. If necessary, we used solid allograft to fill bony defects. Outcomes included bone union as assessed by radiographs, pain as indicated by the American Orthopaedic Foot and Ankle Society scores, and patient satisfaction. Solid arthrodesis was achieved after an average of 12.3 (eight to 26) weeks in the 16 ankles without bone graft interposed between the tibia and talus, and 14.3 (range, 8 to 26) weeks in the 13 ankles with interpositional bone allograft. Radiographs showed that the position of arthrodesis obtained at the time of surgery did not change in any patient up to one year after surgery. The mean American Orthopaedic Foot and Ankle Society (AOFAS) Hindfoot Score increased from 37 (range, 20 to 63) preoperatively to 68 (range, 50 to 92) at the last followup. Twenty-seven patients (93%) were

    Anterior tibial stress fractures are associated with high rates of delayed union and nonunion, which can be particularly devastating to a professional athlete who requires rapid return to competition. Current surgical treatment strategies include intramedullary nailing, which has satisfactory rates of fracture union but an associated risk of anterior knee pain. Anterior tension band plating is a biomechanically sound alternative treatment for these fractures. Tension band plating of chronic anterior tibial stress fractures leads to rapid healing and return to physical activity and avoids the anterior knee pain associated with intramedullary nailing. Case series; Level of evidence, 4. Between 2001 and 2013, there were 13 chronic anterior tibial stress fractures in 12 professional or collegiate athletes who underwent tension band plating after failing nonoperative management. Patient charts were retrospectively reviewed for demographics, injury history, and surgical details. Radiographs were used to assess time to osseous union. Follow-up notes and phone interviews were used to determine follow-up time, return to training time, and whether the patient was able to return to competition. Cases included 13 stress fractures in 12 patients (9 females, 3 males). Five patients were track-and-field athletes, 4 patients played basketball, 2 patients played volleyball, and 1 was a ballet dancer. Five patients were Division I collegiate athletes and 7 were professional or Olympic athletes. Average age at time of surgery was 23.6 years (range, 20-32 years). Osseous union occurred on average at 9.6 weeks (range, 5.3-16.9 weeks) after surgery. Patients returned to training on average at 11.1 weeks (range, 5.7-20 weeks). Ninety-two percent (12/13) eventually returned to preinjury competition levels. Thirty-eight percent (5/13) underwent removal of hardware for plate prominence. There was no incidence of infection or nonunion. Anterior tension band plating for chronic tibial stress

    The purpose of the present study was to retrospectively evaluate the outcomes of patients who underwent combined medial unicompartmental knee arthroplasty (UKA) and anterior cruciate ligament (ACL) reconstruction. The hypothesis was that this procedure would lead to a high success rate in patients affected by isolated medial unicompartmental osteoarthritis and concomitant ACL deficiency. Fourteen patients with primary ACL lesion and concomitant medial compartment symptomatic osteoarthritis treated from 2006 to 2010 were followed up for an average time of 26.7 months (SD 4.2). Assessment included KOOS score, Oxford Knee score, American Knee Society scores, WOMAC index of osteoarthritis, Tegner activity level and objective examination including instrumented laxity test with KT-1000 arthrometer. Radiological assessment was done with standard simple radiographs in order to get information about any presence of loosening of the components. KOOS score, OKS, WOMAC index and the AKSS improved significantly after surgery (p reconstruction is a valid therapeutic option for the treatment of combined medial unicompartmental knee osteoarthritis and ACL deficiency in young and active patients and confirms subjective and objective clinical improvement 2 years after surgery. The use of a fixed-bearing prosthesis represents a reliable feature as it allows to overcome problems of improper ligament tensioning during the implantation of the components. IV.

    Fear of reinjury is associated with cessation of sport after anterior cruciate ligament (ACL) reconstruction despite normal postoperative knee function. The objective of this study is to describe factors informing athletes' experience of fear of reinjury post ACL reconstruction, in athletes who cited fear as the sole reason for not returning to their pre-injury level of sport. Mixed-methods study design of qualitative and a preliminary quantitative component. A conveniently selected private hospital. Ten male and two female athletes, aged between 19 and 45 years, were eligible for the interview from 68 male and 32 female potential participants (age range 17-50) who underwent an ACL reconstruction using any graft type, excluding revision or multi-ligament surgery. To explore factors informing fear of reinjury in participants citing fear of reinjury as the sole reason for not returning to sport, albeit normal knee function. From the participant interview, four themes emerged: undergoing the surgery and recovery again, nature of the pre-injury sport imposing risk of reinjury, personality traits, and social priorities. Clinicians should be aware of factors informing fear of reinjury post ACL reconstruction. Modifiable fears including pain, mode and length of rehabilitation and psychological factors should be considered during rehabilitation to potentially improve the return to sport rate.

    Full Text Available ABSTRACT Introduction In high stage vaginal prolapse, recurrence risk patients, anterior and apical defects need to be addressed in the same procedure. The pre-molded commercial mesh kits are expensive and not always available. Alternative effective and safe treatment ways, with lower costs are desirable. Objective To present long term follow-up of patients treated with a homemade mesh shape to correct high stage prolapses. Materials and Methods We describe prospectively 18 patients with anterior and apical vaginal prolapses, stages III and IV, repaired using this specific design of mesh. All patients were submitted to pre-operative clinical evaluation and urodynamics. Prolapse was classified using the pelvic organ prolapse quantification (POP-Q. Intervention Prolapse surgery, using a six arms prolene mesh, through a single anterior vaginal incision. Outcome Measurements: POP-Q, patients satisfaction, descriptive statistical analysis. Results Between February 2009 and Oct 2010, 18 consecutive women underwent the above-mentioned surgery. Mean age was 68 years. At a mean follow-up of .,4 years (5 to 5.8 years, 16 (89% patients were continent, mean Ba point came from +4.7cm to - 2.5cm, mean C point from +2.8cm to -6.6cm and mean Bp point from +1.3 to -1.7cm. There were two (11% objective failures, but all the patients were considered success subjectively. There were two cases of mesh vaginal extrusion. Conclusions The homemade six arms prolene mesh allows concomitant correction of anterior and apical prolapses, through a single anterior vaginal incision, being an effective, safe and affordable treatment option when mesh is needed.

    Full Text Available Background: Low anterior rectal resection is an option for low rectal cancer. The aim of this study was to assess the clinical and manometric findings before and after low anterior resection in patients with rectal cancer. Methods: In a before-after prospective experimental study, 29 patients with colon cancer who were candidate for elective low anterior resection surgery in Imam Khomeini hospital were enrolled. In preoperative period, the data regarding the anorectal function were gathered and all the patients were assessed by an eight channel rectal manometer. After the surgery, patients were evaluated regarding current anorectal function and underwent rectal manometry for the second time. Results: The mean of defecation time was significantly higher in postoperative period compared with preoperative period (2.48±0.78 vs. 0.94±0.36 time per day. In postoperative period, gas incontinence was significantly higher in comparison to the preoperative period (27.59% vs. 0%. However, the fecal incontinence rates were comparable. Compared with preoperative period, max resting pressure was significantly reduced in postoperative period (53.20±17.45 vs. 64.32±17.33 mmHg. The same was true about max squeezing pressure (140.21±35.50 vs. 150.37±33.16 mmHg. Urgency also increased in postoperative period (48.28% vs. 0%. Conclusions: The results of this study revealed that following low anterior resection surgery for patients with rectal cancer, the defecation time, gas incontinence and urgency increase but max resting and squeezing pressure decrease.

    2016-01-01

    Historically anterior cruciate ligament (ACL) injuries have been diagnosed poorly. A paper published in Injury in 1996 showed that less than 10% of patients with an ACL injury had the diagnosis made by the first physician to see them and that the average delay from first presentation to diagnosis was 21 months. The aim of our study was to investigate whether an improvement has been made over the last two decades in diagnosing ACL injuries. We identified 160 patients who had an ACL reconstruction performed by a single surgeon between October 2004 and December 2011 and for whom a complete data set was available. Data was extracted retrospectively from the hospital notes and a dedicated patient database. We performed a sub-group analysis comparing patients seen prior to the introduction of an acute knee injury clinic in April 2007 and patients seen after the introduction of the clinic. 75.1% (120/160) of patients presented first to an emergency department (ED) or to their general practitioner (GP), but only 14.4% (23/160) were diagnosed on initial presentation. The median number of healthcare professionals a patient saw prior to a diagnosis of ACL injury was 3. The median delay from injury to presentation was 0 weeks (range 0-885), injury to diagnosis 13 weeks (0-926), presentation to diagnosis 10 weeks (0-924), presentation to a specialist knee clinic 24 weeks (0-1006), and specialist knee clinic to surgery 13 weeks (0-102). The median total time from injury to surgery was 42 weeks (0-1047). Following the implementation of an acute knee injury clinic in 2007, the median delay from presentation to surgery dropped from 59 weeks to 36 weeks (p = 0.050) and there was a significant decrease in the median delay from specialist knee clinic to surgery from 23 to 11 weeks (p=0.002). Over the past two decades there appears to have been little improvement in the early diagnosis of ACL injuries, with only 14.4% of patients being diagnosed correctly at initial presentation. We

    We have report two cases of aphasia that had infarcts in the distribution of the left or right anterior cerebral artery, as confirmed by computed tomography. Case 1 is a right-handed, 65-year-old man in whom computerized tomographic scanning revealed an infarction of the territory of the left anterior cerebral artery after the clipping of the anterior communicating artery aneurysm. The standard language test of aphasia (SLTA) revealed non-fluent aphasia with dysarthria, good comprehension, almost normal repetition with good articulation, and a defectiveness in writing. This syndrome was considered an instance of transcortical motor aphasia. Although three years had passed from the onset, his aphasia did not show any improvement. Case 2 is a 37-year-old man who is right-handed but who can use his left hand as well. He was admitted because of subarachnoid hemorrhage from an anterior communicating aneurysm. Because of postoperative spasm, an infarction in the distribution of the right anterior cerebral artery developed. He was totally unable to express himself vocally, but he could use written language quite well to express his ideas and had a good comprehension of spoken language. This clinical picture was considered that of an aphemia. After several weeks, his vocalization returned, but the initial output was still hypophonic. (J.P.N.)

    2016-01-01

    Context: Given its young, predominately male demographics and intense physical demands, the US military remains an ideal cohort for the study of anterior shoulder instability. Evidence Acquisition: A literature search of PubMed, MEDLINE, and the Cochrane Database was performed to identify all peer-reviewed publications from 1950 to 2016 from US military orthopaedic surgeons focusing on the management of anterior shoulder instability. Study Design: Clinical review. Level of Evidence: Level 4. Results: The incidence of anterior shoulder instability events in the military occurs at an order of magnitude greater than in civilian populations, with rates as high as 3% per year among high-risk groups. With more than 90% risk of a Bankart lesion and high risk for instability recurrence, the military has advocated for early intervention of first-time shoulder instability while documenting up to 76% relative risk reduction versus nonoperative treatment. Preoperative evaluation with advanced radiographic imaging should be used to evaluate for attritional bone loss or “off-track” engaging defects to guide comprehensive surgical management. With complex recurrent shoulder instability and/or cases of clinically significant osseous lesions, potential options such as remplissage, anterior open capsular procedures, or bone augmentation procedures may be preferentially considered. Conclusion: Careful risk stratification, clinical evaluation, and selective surgical management for at-risk military patients with anterior shoulder instability can optimize the recurrence risk and functional outcome in this population.

    The anterior abdominal wall has received little attention in the ultrasonic evaluation. However recently the improved resolution of ultrasound scanning devices has made possible routine examination of the anterior abdominal wall. The authors evaluated ultrasonographic findings of anterior abdominal wall lesions in 27 cases for 1 year(from July '82 to Aug. '83), which were finally diagnosed pathologically and clinically. The results were as follows: 1. Well defined peritoneal line and layers of the anterior abdominal wall made it possible to localize the lesions accurately from adjacent structures. 2. Abscess and hematoma were lower in echogenecity than adjacent tissues, such as muscle layer or subcutaneous fat space and were well delineated from normal structures. 3. In hernia, easy differentiation was made due to oval shape, poor or decreased echo pattern and protrustion from skin layer. Conclusively, in the doubtful cases of palpable mass in the abdominal wall, postoperative complications of sequele, such as accurately but also the guide of treatment. Ultrasonography of anterior abdominal wall is useful to demonstrate the exact location, extent of the lesions and to decrease the frequency of useless laparatomy

    We evaluate the importance of cancer spread to the lymphatic system in the posterior triangle. The posterior triangle tissues of 51 radical neck specimens were serially sectioned and studied for metastic involvement. The findings were correlated with the findings in the anterior triangle and the primary tumor. Of the 51 neck operations performed, 25 were elective and 26 were therapeutic for carcinoma of the larynx, pharynx, and oral cavity. Metastasis in the anterior triangles was detected in 88.4% of the therapeutic group and in 24.0% of the elective group. However, no metastasis in the posterior triangel was found in either group, regardless of the site of the tumor. We suggest that the posterior triangle can be totally preserved in radical neck surgery, which may make preservation of the spinal accessory nerve a more likely practice.

    Three-dimensional computed tomographic (3D-CT) angiography is a widespread imaging modality for intracranial vascular lesions. However, 3D-CT angiograms of an anterior communicating artery aneurysm associated with acute retrobulbar optic neuropathy have not been previously described. We present 3D-CT angiograms of an aneurysm of the anterior communicating artery that caused subarachnoid hemorrhage and vision loss in a 39-year old man. The 3D-CT angiograms were consistent with findings identified directly during surgery.

    Full Text Available The aims of this study are to describe the epidemiological characteristics of anterior cruciate ligament reconstructions in a private hospital in Brazil and to determine trends in medical practice for comparison with previous studies.We retrospectively reviewed the anterior cruciate ligament institutional register to obtain data from all patients who underwent primary anterior cruciate ligament reconstruction from July 2014 to June 2016. Descriptive statistics were used to summarize the sample. Specific statistical tests were used to assess associations between the meniscal lesion and other variables.During the study period, 72.6% out of 500 patients were male. The mean age at surgery was 35.1 years. The mean age was higher among females than among males (37.3 ± 12.1 vs 34.3 ± 10.8 years. The median time from injury to surgery was 44 days. The most common femoral and tibial fixations used were suspensory fixation (60.8% and interference screw (96%, respectively. The most commonly used graft was hamstring tendon (70.2%, followed by bone-patellar tendon-bone (28.8%. A meniscal lesion was noted in 44.8% of cases. Partial meniscectomy was performed in 69.5% of meniscal lesions, and meniscal repair was performed in 14.1% of lesions. The mean length of hospital stay was 1.4 days. The proportion of men in the group of patients with an associated meniscal lesion was higher than that in the group of patients without a meniscal lesion (p = 0.007.In this study, we identified that the vast majority of surgeries were performed in male patients in all age groups, and patients older than 30 years and with a short time from injury to surgery predominated. Concerning surgical technique, we noted a low rate of meniscal repair and a higher preference for the use of hamstring graft and suspensory fixation on the femoral side.

    The anterior cruciate ligament (ACL) is the most commonly-injured knee ligament during sporting activities. After injury, most individuals experience episodes of the knee giving way during daily activities (non-copers). Non-copers demonstrate asymmetrical quadriceps strength and movement patterns which could have long-term deleterious effects on the integrity of the knee joint. The purpose of this study was to determine if non-copers resolve their strength and movement asymmetries within two years after surgery. 26 non-copers were recruited to undergo pre-operative quadriceps strength testing and 3-dimensional gait analysis. Subjects underwent surgery to reconstruct the ligament followed by physical therapy focused on restoring normal range of motion, quadriceps strength, and function. Subjects returned for quadriceps strength testing and gait analysis six months and two years after surgery. Acutely after injury, quadriceps strength was asymmetric between limbs, but resolved six months after surgery. Asymmetric knee angles, knee moments, and knee and hip power profiles were also observed acutely after injury and persisted six months after surgery despite subjects achieving symmetrical quadriceps strength. Two years after surgery, quadriceps strength in the involved limb continued to improve and most kinematic and kinetic asymmetries resolved. These findings suggest that adequate quadriceps strength does not immediately resolve gait asymmetries in non-copers. They also suggest that non-copers have the capacity to improve their quadriceps strength and gait symmetry long after ACL reconstruction. PMID:21592482

Surgery was performed between 2009 and 2012 in Clinic of Urology (Clinical Center Nis and Department of Urology (Municipal Hospital Prokuplje. Stress Urinary Incontinence (SUI and anterior vaginal wall prolapse was confirmed in all patients. In all patients with anterior vaginal wall prolapse (grade≥2 both tension free vaginal tape (TVT-O and anterior vaginal wall repair were performed. Pelvic Organ Prolapse Quantification (POPQ system was used for the evaluation of prolapse before and after the surgery. Mean age of patients was 61 years. Spinal anesthesia was performed in thirty patients and general anesthesia in 10 patients. Intraoperative blood loss was under 50 ml. There were no bladder, nerve and blood vessels injuries . Thirty eight out of forty patients (95% were satisfied with the outcome of the surgery. There was a significant correction of prolapse after the surgery. Recurrence of prolapse was found in patients with the high grade prolapse before the surgery, as well as, in patients with the history of previous anterior vaginal repair. Pelvic organ prolapse, congenital or acquired, is supported by the congenital weakness of the pelvic floor.

    2002-03-01

    Implant surgery in association with bone grafting is generally considered less predictive than primary implant surgery. Many reports have been published about implant rehabilitation with bone grafts in atrophic patients. Most of these papers showed a lower implant success rate than primary implantology. The aim of this study is to verify if it's possible to warrant similar results between the two types of implantology, if such procedures are performed following effective protocols and criteria. From 1995 to 1999, 43 severely atrophic edentulous patients were treated in our Clinic with 63 autologous bone grafts and delayed implantology; 45 patients were treated with traditional implantology. 284 fixtures were positioned. The success rate in grafted implantology versus traditional implantology was compared for every maxillary and mandibular region. Furthermore, success rate in implantology of the anterior maxilla versus the poster maxilla in grafted patients was compared. The statistical considerations were performed with c2 test (p<0.05). The statistical analysis evidenced not significative difference in the implant success rate between grafted and not grafted patients in the anterior (p=0.23) and in the posterior maxilla (p=0.35). There was not significative difference in the implant success rate between grafted and not grafted patients in the anterior mandible (p=0.54) and in the posterior mandible (p=0.54). There was not significative difference in the implant success rate between the anterior and posterior grafted maxilla (p=0.21). The results obtained show that if close surgical protocol is performed it is possible to obtain no prognostic difference between the two METHODS.

    Because of suspected rupture of the anterior cruciate ligament sixteen acute traumatised patients were investigated by MR and arthroscopy. The MR diagnosis of a lesion of the anterior cruciate ligament proved to be correct by arthroscopy in fifteen of sixteen cases. Diagnostic criteria for lesions of the anterior cruciate ligament were: increased signal intensity in T 1 - and T 2 weighted images, increased volume and discontinuity of ligamentous structures. Additional MR findings of meniscal tears were correct in three of four cases laterally and in four of four cases medially. Femoral cartilage lesions were correctly identified by MR in three cases. MR normal findings proved to be correct by arthroscopy in another five cases. (orig.) [de

    2014-05-01

    Anterior chamber collapse syndrome has been recognised in various species and is associated with early-life ocular disease or trauma. It is important to differentiate this acquired condition from a congenital malformation. An adult female koala (Phascolarctos cinereus) was referred for assessment of buphthalmos and severe keratitis of the right eye. The degree of keratitis obstructed examination of intraocular structures. Enucleation of the affected eye was performed and the histopathological diagnosis was anterior chamber collapse syndrome and secondary glaucoma. This case contributes to the limited information available in the literature on anterior chamber collapse syndrome, a disease unique in having secondary glaucoma with minimal or no inflammation. The case also expands the literature available on ocular disease in koalas. More specifically, this is the only reported case of glaucoma, of any aetiology, in the koala. © 2014 Australian Veterinary Association.

The diagnosis of underlying autoimmune disease involves a multidisciplinary approach.Case report: A 42-year-old African American female presented to the Eye Clinic at the San Francisco Veteran Affairs Medical Center, with a tremendously painful left eye, worse on eye movement, with marked injection of conjunctiva. There was mild swelling of the upper eyelid. Visual acuity was unaffected, but there was a mild red cap desaturation. The posterior segment was unremarkable. The initial differential diagnoses included anterior scleritis and orbital inflammatory disease. Oral steroid treatment was initiated with rapid resolution over a few days. Orbital imaging was unremarkable, and extensive laboratory work-up was positive only for antinuclear antibodies. The patient was diagnosed with idiopathic diffuse, nonnecrotizing anterior scleritis and has been followed for over 5 years without recurrence. The rheumatology clinic monitors the patient closely, as suspicion remains for potential arthralgias including human leukocyte antigen-B27-associated arthritis, lupus-associated arthritis, seronegative rheumatoid arthritis, recurrent juvenile idiopathic arthritis, and scleroderma, based on her constitutional symptoms and clinical presentation, along with a positive anti-nuclear antibody lab result.Conclusion: Untreated anterior scleritis can progress to formation of cataracts, glaucoma, uveitis, corneal melting, and posterior segment disease with significant risk of vision loss. Patients with anterior scleritis must be aggressively treated with systemic anti

    SYNOPSIS The management of patients after anterior cruciate ligament reconstruction should be evidence based. Since our original published guidelines in 1996, successful outcomes have been consistently achieved with the rehabilitation principles of early weight bearing, using a combination of weight-bearing and non–weight-bearing exercise focused on quadriceps and lower extremity strength, and meeting specific objective requirements for return to activity. As rehabilitative evidence and surgical technology and procedures have progressed, the original guidelines should be revisited to ensure that the most up-to-date evidence is guiding rehabilitative care. Emerging evidence on rehabilitative interventions and advancements in concomitant surgeries, including those addressing chondral and meniscal injuries, continues to grow and greatly affect the rehabilitative care of patients with anterior cruciate ligament reconstruction. The aim of this article is to update previously published rehabilitation guidelines, using the most recent research to reflect the most current evidence for management of patients after anterior cruciate ligament reconstruction. The focus will be on current concepts in rehabilitation interventions and modifications needed for concomitant surgery and pathology. PMID:22402434

    Purpose: To review pre- and postoperative fast spin-echo (FSE) MR images of disc herniation and spondylosis in patients after spinal cervical surgery. Material and Methods: Data were reviewed of 68 patients after anterior discectomy and fusion (ADF) operations using the Cloward technique with solid single level (C5-C6 or C6-C7) or 2-level fusions (C5-C7). The average interval from surgery to review was 37 months. Age- and sex-matched controls without neck problems were examined. Results: Preoperatively, the fusion groups had a higher incidence of protruded disc, and anterior and posterior osteophytes at the levels to be fused than the controls. Postoperatively, there was a significantly higher incidence of posterior osteophytes at the fused levels compared with the controls. Furthermore, the disc herniations and anterior osteophytes at the levels above and below the operated segments were more frequent in the fusion group. Conclusion: ADF causes acceleration of the degenerative changes at the fused level and at the levels below and above the fused segments. (orig.).

    To report long-term outcome of inferior oblique anterior and nasal transposition in superior oblique palsy. The medical records of patients with superior oblique palsy who underwent inferior oblique anterior nasal transposition were reviewed retrospectively. A comprehensive ophthalmic evaluation, including prism bar cover test and measurement of torsion, was performed for all cases. One-year postoperative results were evaluated for alignment in primary gaze, contralateral gaze, and upgaze; reduction in inferior oblique overaction and changes in fundus torsion to assess long-term outcome of the procedure. A total of 12 patients were included. Three cases also underwent horizontal muscle surgery. Mean age at the time of surgery was 20.6 years. The median preoperative hypertropia was 21.5 Δ (range, 12 Δ -36 Δ ), corrected to 4.5 Δ (range, 2 Δ -10 Δ ) at 12 months postoperatively (P = 0.002). Median inferior oblique overaction decreased from +3 (range, +1 to +4) to 0 (range, -1 to +1). Preoperative fundus extorsion was 19.2° ± 6.7°; postoperative, 0.58° ± 1.8° (P Extorsion was eliminated and head tilt improved in all patients. Inferior oblique anterior and nasal transposition resulted in good long-term outcomes in our patients with superior oblique palsy presenting with hypertropia, inferior oblique overaction, and extorsion in primary gaze.
