The number of amputations performed for vascular disease in Denmark has decreased from 1777 (34.5 per 100,000 population) in 1983 to 1288 (25.0 per 100,000) in 1990, a reduction of 28 per cent. This decline coincided with an increase in vascular surgical activity of up to 100 per cent, including...... a marked rise in the rate of femorodistal reconstruction. Moreover, regional variation in vascular surgical activity correlated with percentage reduction in amputation rate (rS = 0.65, P amputations also decreased in favour of more distal levels during the period...... studied. These findings suggest that vascular surgery may be responsible for the lower amputation rate....

Full Text Available Objectives: To evaluate the functional outcome, morbidity, and viability of foot salvage in diabetic patients. Materials and methods: This prospective case series was conducted from March 2007 to December 2012 at the department of surgery Pakistan Ordnance Factories Hospital, Wah Cantt, Pakistan. 123 males and 26 female patients were included in the study. All the patients were treated after getting admitted in the hospital and wounds were managed with daily dressings, nursing care and debridement of necrotic tissue with adequate antibiotic coverage. Results: In total, 149 patients (mean age: 56±7.52 years with 171 amputations were included in the study. The mean duration of diabetes mellitus (DM was 9±4.43 years. Ninety-seven percent of the patients were diagnosed with type 2 DM. Wound debridement was performed under general anesthesia in 48 (33.2% patients, whereas local anesthesia was used for the rest of the patients after having good glycemic control and improvement in general health. The most common pathogen isolated from the infected wounds was Staphylococcus aureus in approximately 46% cases. Regarding the types of amputation, partial toe amputation was performed in 21 (12.2% cases, second-toe amputation in 60 (35% cases, hallux amputation in 41 (24% cases, multiple toe amputations in 29 (17% cases, bilateral feet involvement was observed in 16 (9.3% cases, and transmetatarsal amputation was performed in 4 (2.3% cases. The wounds healed well except in 19 cases where amputation had to be revised to a more proximal level. Thirty-nine patients died during the study period: 3 died of wound-related complications and 36 died of systemic complications. Conclusion: With the ever-increasing epidemic of DM, the number of patients with diabetic foot ulcers has also significantly risen. Early surgical management with good glycemic control and foot care with close monitoring can decrease amputations and thus foot salvage can be successfully

Amputations involving ten digits are very rare because of different lengths of the digits. A 34-year-old man working in a printing house presented one hour after guillotine amputation involving all ten digits. Surgery was initiated 80 minutes after admission and took seven hours. Under axillary anesthesia, the operation was performed by two teams each consisting of two microsurgeons and two assistants. Replantation was completed without the use of any skin graft or flap. Fingertip examination showed poor arterial circulation in the second, third, and fourth digits of the left hand after 24 hours of replantation and surgical exploration was performed, during which anastomosis of the ulnar digital artery of the second digit was re-established and a Y-shaped vein graft was placed at the level of the third web to restore revascularization of the third and fourth digits. However, these interventions did not prevent the development of necrosis in the distal segment of the fourth digit which resulted in dry gangrene that required amputation. After 38 months of replantation, radiographic examination showed complete union in all fingers without malunion or damage to the joint surface and about 8 degrees of medial angulation in the proximal phalanx of the fourth digit of the right hand. The patient did not have difficulty in performing daily activities and had a considerably good pinching. Losses of active range of motion of the metacarpophalangeal and interphalangeal joints were within the rage of 10 to 30 degrees in both hands. In the assessment of sensation, static and dynamic two-point discrimination test results were 6.1 mm and 4.0 mm, respectively.

Full Text Available Aim of investigation — to analyze the results of treatment of patients with atherosclerotic gangrene of a limb, to identify the causes of adverse outcomes amputation. Materials and methods: We analyzed the results of examination and treatment of 218 patients with atherosclerotic gangrene of the limb. Good outcome of amputation was considered the primary surgical wound healing of the stump. Suppuration, secondary healing, re-amputation and death we attributed to the adverse results of amputation. Results: The adverse outcomes of amputation due to technical errors in surgery, properly chosen level, inadequate drainage of the wound stump, an unsuccessful operation on the arteries of a limb, inadequate empirical antibiotic therapy, patient's age, functional capabilities of myocardium, the duration of critical ischemia, as well as the lack of psychological adaptation of patients before amputation. Conclusion: To decide the need for amputation in patients with atherosclerotic gangrene follows the assessment of possible vascular reconstructive surgery. In determining the level of amputation is necessary to objectively assess the degree of disruption of regional blood flow using multilevel manometry and laser Dopplerflowmetry. In preparation for amputation should be paid special attention to the correction of rheological and coagulation properties of blood, normalization of the functional state of the myocardium, as well as specialized psychotherapeutic training for timely and adequate psychological adaptation of the patient

Objective: To explore the risk factors for lower extremity amputation in patients with diabetic foot. Methods: The clinical data of 1 771 patients with diabetic foot at the Air Force General Hospital of PLA from November 2001 to April 2015 were retrospectively analyzed. The patients were divided into the non-amputation and amputation groups. Within the amputation group, subjects were further divided into the minor and major amputation subgroups. Binary logistic regression analyses were used to assess the association between risk factors and lower extremity amputation. Results: Among 1 771 patients with diabetic foot, 323 of them (18.24%) were in the amputation group (major amputation: 41; minor amputation: 282) and 1 448 (81.76%) in the non-amputation group. Compared with non-amputation patients, those in the amputation group had a longer hospital stay and higher estimated glomerular filtration rate(eGFR)levels. Fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1c), C-reaction protein (CRP), ESR, ferritin, fibrinogen and WBC levels of the amputation group were higher, while hemoglobin albumin, transferrin, TC, TG, HDL-C and LDL-C were lower than those of the non-amputation group (all P diabetic foot. Conclusion: Wagner's grade, ischemia of lower limbs and infection are closely associated with amputation of diabetic foot patients.

A substantial body of evidence documents massive reorganization of primary sensory and motor cortices following hand amputation, the extent of which is correlated with phantom limb pain. Many therapies for phantom limb pain are based upon the idea that plastic changes after amputation...... for the maladaptative plasticity model, we demonstrate for the first time that motor capacities of the phantom limb correlate with post-amputation reorganization, and that this reorganization is not limited to the face and hand representations but also includes the proximal upper-limb....

During replantation of distal fingertip amputation, identification of the artery is the most important but time consuming procedure. Depending on the damaged arterial structure, we classified distal fingertip amputations into 4 zones, on the basis of three dimensional concept. Zone 1 injury was defined as damage to the proximal central pulp artery; zone 2 injury, damage to the branch of the central pulp artery; zone 3 injury, damage to the distal central pulp artery; and zone 4 injury, no injury to the central pulp artery, injury only to the lateral pulp artery. From April 2010 to June 2011, 27 patients were evaluated. Successful replantation was observed in 21 patients. Skin necrosis occurred in six patients. For distal fingertip amputation classification based on the damaged arterial system is an easy method to find out the appropriate artery which should be anastomosed during replantation.

Full Text Available Multidimensional Inventory Check List of Symptoms (SCL-90-r is based on self-evaluation and it has been used for determination of level of: somatisation, obsessive-compulsive symptoms, interpersonal sensitivity, depression, anxiety, hostility, phobias, paranoia and psychosis at persons which are exposed to long term emotional and physical stress. Our goal was to determine relations of physical trauma and psychological changes at persons with lower extremities amputations and to determine factors which influence those changes. Thirty seven persons with lower extremities amputations were examined. The sample included 26 (70.2 % veterans and 11 (29.7 % civilians with diseases related amputations. They voluntarily filled Check List of Symptoms SCL-90-r. Symptoms Inventory includes 9 dimensions of primary symptoms: SCL1-somatisation, SCL2-obsessive-compulsive symptoms, SCL3-interpersonal sensitivity, SCL4-depression, SCL5-anxiety, SCL6-hostility, SCL7-phobias, SCL8-paranoia, SCL9-psychosis and SCL10-extra scale. Inventory includes 90 statements, each evaluated with five-level scale of disorder. Every answer is graded with 0-4 points. Thirty seven persons with lower extremities amputations and average chronological age 46.2 +/- 10.92 years were analyzed. Considering marital status 30 (81.1 % of them were married, 4 (10.8 % were not married and 3 (8.1 % were widowers. Considering level of amputation 27 of them (73.0 % had amputation below knee, 5 (13.5 % of them amputation above knee and 5 of them (13.5 % foot amputation. SCL-90-r in both groups determined high level of sensitivity, anxiety, hostility and paranoia. Veterans showed higher level of paranoia comparing to civilians (p<0.002, and younger veterans and married ones had higher level of paranoia comparing to other veterans (p<0.01.

Air transportation to tertiary care centers of patients with upper extremity amputations has been utilized in hopes of reducing the time to potential replantation; however, this mode of transportation is expensive and not all patients will undergo replantation. The purpose of this study is to review the appropriateness and cost of air transportation in upper extremity amputations. Consecutive patients transported by aircraft with upper extremity amputations in a 7-year period at a level-1 trauma center were retrospectively reviewed. The distance traveled was recorded, along with the times of the injury, referral, transportation duration, arrival, and start of the operation. The results of the transfer were defined as replantation or revision amputation. Overall, 47 patients were identified with 43 patients going to the operating room, but only 14 patients (30%) undergoing replantation. Patients arrived at the tertiary hand surgery center with a mean time of 182.3 minutes following the injury, which includes 105.2 minutes of transportation time. The average distance traveled was 105.4 miles (range, 22-353 miles). The time before surgery of those who underwent replantation was 154.6 minutes. The average cost of transportation was $20,482. Air transportation for isolated upper extremity amputations is costly and is not usually the determining factor for replantation. The type of injury and patients' expectations often dictate the outcome, and these may be better determined at the time of referral with use of telecommunication photos, discussion with a hand surgeon, and patient counseling.

Distal fingertip amputations are common injuries in work- and non-work-related accidents. There is a paucity of evidence to support use of any one treatment. We conducted a study to better understand how surgeon and patient factors influence the treatment preferences for distal fingertip amputations among a cross section of US and international hand surgeons. We sent a 16-question survey to the American Association for Hand Surgery and reciprocal international hand societies and analyzed the response data using a logistic regression model. We hypothesized that hand surgeons' treatment preferences would be varied and influenced by surgeon and patient demographics. One hundred ninety-eight hand surgeons (62% US, 38% international) responded to the survey. For each clinical scenario (Allen levels 2, 3, and 4 and volar oblique amputations), there were wide variations in treatment preferences. Wound care was less likely performed by surgeons with more than 30 years of experience or plastic surgery backgrounds. Replantation was less likely performed by US surgeons and private practice surgeons. Pedicle and homodigital flaps were more commonly performed internationally. Surgeons in practice for less than 5 years were more likely to perform skeletal shortening. For all levels and orientations of fingertip amputation queried, there is a wide range of treatment preferences. Our survey results highlight the need for a prospective randomized trial to elucidate the most effective treatments for fingertip amputations.

Even if a digital replantation is not possible, we present a series of nine cases of fingertip amputations treated with clinical efficacy by using a composite graft from the amputated finger part. All of our eight patients (four children and four adults) were traumatically amputated. The level of amputation passed by the bunch of P3 and carried partially or completely the ungula. The reposition was always performed under local anaesthesia. Our evaluation related on the survival of the composite grafts, the functional and the aesthetic result. The composite grafts were revascularised in eight amputations out of nine, with a satisfactory remote result on the function as well as aesthetic level. After a short recall of the alternative surgical methods of the treatment of the fingertip amputations, we will insist on the simplicity and the reliability of the repositioning of a composite graft, recommended for us from the start and depending on the traumatic level. In the event of a failure, surgeons still have the possibility of realising the other alternative surgical methods. 2009. Published by Elsevier SAS.

[Knee disarticulation and through-knee amputation].

Science.gov (United States)

Baumgartner, R

2011-10-01

A knee disarticulation or a through-knee stump is superior compared to a transfemoral stump. The thigh muscles are all preserved, and the muscle balance remains undisturbed. The range of motion of the hip joint is not limited. The bulbous shape of the stump allows full weight bearing at the stump end and can easily be fitted with a prosthesis. An amputee with a bilateral knee disarticulation is able to walk "barefoot". A more distal amputation level, e.g., an ultra-short transtibial amputation, is not possible. Important alternative to transfemoral amputations. Possible for any etiology except for Buerger-Winiwarter's disease. New indications are infected and loosened total knee replacements. Preservation of the knee joint is possible. Knee disarticulation is a very atraumatic procedure, compared to transfemoral amputations. Neither bones nor muscles have to be severed, just skin, ligaments, vessels, and nerves. Even the meniscal cartilages may be left in place to act as axial shock absorbers. The cartilage of the femur is not resected, but only bevelled in case of osteoarthritis. There are no tendon attachments or myoplastic procedures necessary. The patella remains in place and is held in position only by the retinacula. Skin closure must be performed without the slightest tension, and if possible not in the weight-bearing area. Transcondylar amputations across the femoral condyles only are indicated when there are not sufficient soft tissues for wound closure of a knee disarticulation. Alternatives as the techniques of Gritti, Klaes, and Eigler, the shortening of the femur and the Sauerbruch's rotation plasty [14] are presented and discussed. The risk of decubital ulcers is rather high. Correct bandaging of the stump is, therefore, particularly important. Prosthetic fitting is possible 3-6 weeks after surgery. The type of prosthesis depends on the amputee's activity level. The superior performance of amputees with knee disarticulations in sports prove the

Amputation revision rates following major upper-extremity amputations have not been previously reported in a large cohort of patients. We hypothesized that the revision rates following major upper-extremity amputation were higher than the existing literature would suggest, and that surgical treatment of complications and persistent symptoms would lead to improved outcomes. We performed a retrospective analysis of a consecutive series of ninety-six combat-wounded personnel who had sustained a total of 100 major upper-extremity amputations in Operation Iraqi Freedom and Operation Enduring Freedom. Prerevision and postrevision outcome measures, including prosthesis use and type, the presence of phantom and residual limb pain, pain medication use, and return to active military duty, were identified for all patients. All amputations resulted from high-energy trauma, with 87% occurring secondary to a blast injury. Forty-two residual limbs (42%) underwent a total of 103 repeat surgical interventions. As compared with patients with all other levels of amputation, those with a transradial amputation were 4.7 (95% confidence interval [CI]: 1.75 to 12.46) times more likely to have phantom limb pain and 2.8 (95% CI: 1.04 to 7.39) times more likely to require neuropathic pain medications. In the group of patients who underwent revision surgery, regular prosthesis use increased from 19% before the revision to 87% after it (p < 0.0001). In our cohort, revision amputation to address surgical complications and persistently symptomatic residual limbs improved the patient's overall acceptance of the prosthesis and led to outcomes equivalent to those following amputations that did not require revision.

Replantation of fingertip amputation by using the pocket principle in adults.

1999-04-01

There are several treatment modalities for zone 1 or zone 2 fingertip amputations that cannot be replanted by using microsurgical techniques, such as delayed secondary healing, stump revision, skin graft, local flaps, distant flaps, and composite graft. Among these, composite graft of the amputated digit tip is the only possible means of achieving a full-length digit with a normal nail complex. The pocket principle can provide an extra blood supply for survival of the composite graft of the amputated finger by enlarging the area of vascular contact. The surgery was performed in two stages. The amputated digit was debrided, deepithelialized, and reattached to the proximal stump. The reattached finger was inserted into the abdominal pocket. About 3 weeks later, the finger was removed from the pocket and covered with a skin graft. We have consecutively replanted 29 fingers in 25 adult patients with fingertip amputations by using the pocket principle. All were complete amputations with crushing or avulsion injuries. Average age was 33.64 years, and men were predominant. The right hand, the dominant one, was more frequently injured, with the middle finger being the most commonly injured. Of the 29 fingers, 16 (55.2 percent) survived completely and 10 (34.5 percent) had partial necrosis less than one-quarter of the length of the amputated part. The results of the above 26 fingers were satisfactory from both functional and cosmetic aspects. Twenty of the 29 fingers, which had been followed up for more than 6 months (an average of 16 months), were included in a sensory evaluation. Fifteen of these 20 fingers (75 percent) were classified as "good" (static two-point discrimination of less than 8 mm and normal use). From the overall results and our experience, we suggest that the pocket principle is a safe and valuable method in replantation of zone 1 or zone 2 fingertip amputation, an alternative to microvascular replantation, even in adults.

Cycling with any form of limb amputation has progressed from an activity of leisure or rehabilitation to elite level competition as part of the Paralympic Games programme. While it is often proposed that research into sport with an amputation can be extremely limited, this study intended to identify the volume, type and historical strategy in this area. This study comprises a documented systematic literature review of cycling undertaken with any form of limb amputation. This study used four online search engines to identify relevant peer-reviewed literature. These included SPORTDiscus, CINAHL, Scopus and MEDLINE. Google Scholar was also used as a secondary source. The initial results were then subjected to a set of pre-defined inclusion criteria. The resulting publications were then analysed for content and thematic commonality. The review identified 20 articles which met pre-defined inclusion criteria. The identified peer-reviewed publications were dated from the period 2004 to 2014. Three clear themes emerged from the historical research. There was both a paucity of peer-reviewed literature with respect to cycling with an amputation and the design of adaptive or assistive technology to replace limb loss. However, publications have been rising substantially over the last 5 years. This review study established the historical strategy and content of cycling with an amputation and identified the existing research themes. This will assist in summarising the current level of knowledge and help signpost such work in the future. © The International Society for Prosthetics and Orthotics 2015.

While Amputee Mobility Predictor scores differ between Medicare Functional Classification Levels (K-level), this does not demonstrate that the Amputee Mobility Predictor can accurately predict K-level. To determine how accurately K-level could be predicted using the Amputee Mobility Predictor in combination with patient characteristics for persons with transtibial and transfemoral amputation. Prediction. A cumulative odds ordinal logistic regression was built to determine the effect that the Amputee Mobility Predictor, in combination with patient characteristics, had on the odds of being assigned to a particular K-level in 198 people with transtibial or transfemoral amputation. For people assigned to the K2 or K3 level by their clinician, the Amputee Mobility Predictor predicted the clinician-assigned K-level more than 80% of the time. For people assigned to the K1 or K4 level by their clinician, the prediction of clinician-assigned K-level was less accurate. The odds of being in a higher K-level improved with younger age and transfemoral amputation. Ordinal logistic regression can be used to predict the odds of being assigned to a particular K-level using the Amputee Mobility Predictor and patient characteristics. This pilot study highlighted critical method design issues, such as potential predictor variables and sample size requirements for future prospective research. Clinical relevance This pilot study demonstrated that the odds of being assigned a particular K-level could be predicted using the Amputee Mobility Predictor score and patient characteristics. While the model seemed sufficiently accurate to predict clinician assignment to the K2 or K3 level, further work is needed in larger and more representative samples, particularly for people with low (K1) and high (K4) levels of mobility, to be confident in the model's predictive value prior to use in clinical practice.

Full Text Available Advanced Technology and early detection of disease by recent improvements in investigation modalities lead to decreased incidents of amputations while Road Traffic Accidents (RTA increase. Furthermore, it leads to variation and decreased morbidity, mortality and accidents (crush injuries, and better equipped and trained staff, specialist services, diabetic food, rehabilitation centres, and giving good support physically and psychologically for Amputated patients. OBJECTIVE To know incidence rates of Emergency Amputation who attended causality with advanced disease and severe Trauma. METHODOLOGY The study is done over a period of one year i.e. between June 2015 to June 2016 who attended causality with advanced and severe disease affecting the limbs either due to diabetes, trauma or vascular diseases. RESULTS During one-year period, total 6,371 patients attended for general surgery OP. In those, 187 patients needed emergency surgery which included both major and minor operations. Among those, 81 patients were amputated. CONCLUSION As per our available records and observation, even though there is increased literacy and access to advanced technology, there is still increased incidence of patients undergoing amputations due to diseases. Therefore, there is a need to improve awareness and importance of early detection of diabetes, hazards of smoking, and regular general health checkups for patients at root level. With that we can treat diabetes and/or any disease in time. So there must be awareness in peripheral health staff i.e. PHC, subcentres, and community health centres about early detection of disease which in turn improves the quality of life of the patient. Due to diabetes slight injury to the glucose laden tissue may cause chronic infection and ulcer formation.(1 The tumours are seen commonly in the age group of 20-40 years after bone fusion, bones affected commonly are those around the knee (lower end of knee, upper end of tibia.

Patients with body integrity identity disorder (BIID) experience a strong desire for amputation from very early on. BIID patients are often dismissed when they share their wish for amputation with surgeons. Consequently, patients resort to self-amputation, including complications and sometimes death. BIID patients are not psychotic and are mentally competent to oversee the consequences of an elective amputation. The authors offer arguments in favor of elective amputation.

Osteomyelitis is common in diabetic foot infections and medical management can lead to poor outcomes. Surgical management involves sending histopathologic and microbiologic specimens which guides future intervention. We examined the effect of obtainment of surgical margins in patients undergoing forefoot amputations to identify patient characteristics associated with outcomes. Secondary aims included evaluating interobserver reliability of histopathologic data at both the distal-to and proximal-to surgical bone margin. Data were prospectively collected on 72 individuals and was pooled for analysis. Standardized method to retrieve intraoperative bone margins was established. A univariate analysis was performed. Negative outcomes, including major lower extremity amputation, wound dehiscence, reulceration, reamputation, or death were recorded. Viable proximal margins were obtained in 63 out of 72 cases (87.5%). Strong interobserver reliability of histopathology was recorded. Univariate analysis demonstrated preoperative platelets, albumin, probe-to-bone testing, absolute toe pressures, smaller wound surface area were associated with obtaining viable margins. Residual osteomyelitis resulted in readmission 2.6 times more often and more postoperative complications. Certain patients were significantly different in the viable margin group versus dirty margin group. High interobserver reliability was demonstrated. Obtainment of viable margins resulted in reduced rates of readmission and negative outcomes. Prognostic, Level I: Prospective.

Full Text Available The frequency of traumatic amputations is constantly growing, which is associated with the development of transport and modern technology, military conflicts. Aim: To improve the results of treatment of patients with wound and functional defects after injury by developing a comprehensive program of surgical treatment to restore the shape and function of the trunk and limbs. Materials and methods. From 2010 to 2016 52 patients were observed in the clinic. Traumatic amputations at the hip level were observed in 14 patients, at the level of the upper third of the tibia – in 7 patients, at the level of the lower third of the tibia – 3, foot – 6. Simultaneous amputation of two lower limbs was observed in 2 patients. Amputation of upper limbs at shoulder level was observed in 3 patients, hand – 2, fingers – 15 patients. Among the reasons of limb amputations road traffic injuries occupied the leading position – 77.8 %. Combined injury (mechanical and thermal was observed in 1 case – there was a burn of amputated limb. In 31 cases (59.6 % there was complete amputation of a limb, incomplete – in 21 cases (40.4 %. Results. As a result of these tactics, only in 3 cases we had to do limb reamputation due to the inconsistency of the stump. In 22 patients for the conservation of sufficient length and the optimum shape of the stump the imposition of primary sutures was not made. At the stage of recovery of tissue covering the stump in 16 cases the closure of wound defects with simple split skin graft was fulfilled, 3 – with plastic by local tissues, 4 – islet flap on the peripheral stalk, 1 – plastic flat bridging flap, 20 operations were performed with tubular migratory classic flap. There were no complications in the postoperative period. Conclusions. The main principles in establishing the indications for reconstruction of large limb segments should be both critical attitude to the operation and strict individual approach to each

Residual limb infection following amputation is a devastating complication, resulting in delayed rehabilitation, repeat surgery, prolonged hospitalisation and poor functional outcome. The aim of this study was to identify variables predicting residual limb infection following non-salvageable lower limb trauma. All cases of non-salvageable lower limb trauma presenting to a specialist centre over 5 years were evaluated from a prospective database and clinical and management variables correlated with the development of deep infection. Forty patients requiring 42 amputations were identified with a mean age of 49 years (±19.9, 1SD). Amputations were performed for 21 Gustilo IIIB injuries, 12 multi-planar degloving injuries, seven IIIC injuries and one open Schatzker 6 fracture. One limb was traumatically amputated at the scene and surgically revised. Amputation level was transtibial in 32, through-knee in one and transfemoral in nine. Median time from injury to amputation was 4 days (range 0-30 days). Amputation following only one debridement and within 5 days resulted in significantly fewer stump infections (p = 0.026 and p = 0.03, respectively, Fisher's exact test). The cumulative probability of infection-free residual limb closure declined steadily from day 5. Multivariate analyses revealed that neither the nature of the injury nor pre-injury patient morbidity independently influenced residual limb infection. Avoiding residual limb infection is critically dependent on prompt amputation of non-salvageable limbs. Copyright © 2012 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

The lower extremity amputations diminish the quality of life of patients with Diabetes Mellitus (DM). The aim of this study was to describe the lower extremity amputation rates in subjects with DM in the Mexican Social Security Institute (IMSS), comparing 2004 and 2013. A comparative cross-sectional study was done. Amputations were identified from the hospital records of System of Medical Statistics (DataMart). The DM patient census was obtained from the System of Integral Attention to Health. Major and minor amputations rates were expressed per 100,000 DM patients. We observed 2 334 340 and 3 416 643 DM patients during 2004 and 2013, respectively. The average age at the time of the amputation was similar in 2004 and 2013 (61.7 and 65.6 years old for minor and major amputations respectively). The major amputations rates were 100.9 and 111.1 per 100 000 subjects with DM in during 2004 and 2013 (p = 0.001); while minor amputations rates were 168.8 and 162.5 per 100 000 subjects with DM in during 2004 and 2013 respectively (p = 0.069). The lower extremity amputations rates at IMSS are very high compared with that reported in developed countries. The major amputations rate increased in 2013 compared with 2004.

BACKGROUND: Transfemoral amputation is considered the last treatment option for failed knee arthroplasty. The extent to which this procedure is performed is not well known. The purpose of this study was to identify the incidence and causes of amputation following failure of knee arthroplasty...... were followed by amputation. Hospital records of all identified cases were reviewed. A competing-risk model was used to estimate the cumulative incidence of amputation. Differences in cumulative incidences were analyzed with use of the Gray test. RESULTS: A total of 115 amputations were performed...... for causes related to failed knee arthroplasty. The 15-year cumulative incidence of amputation was 0.32% (95% confidence interval [CI], 0.23% to 0.48%). The annual incidence of amputation following arthroplasties performed from 1997 to 2002 was 0.025% compared with 0.018% following arthroplasties performed...

Leisure activities following a lower limb amputation.

Couture, Mélanie; Caron, Chantal D; Desrosiers, Johanne

2010-01-01

The aim of this study was to describe leisure activities, leisure satisfaction and constraints on participation in leisure following a unilateral lower limb amputation due to vascular disease. This study used a mixed-method approach where 15 individuals with lower limb amputation completed the individual leisure profile 2-3 months post-discharge from rehabilitation. A subsample (n = 8) also participated in semi-structured interviews analysed using the Miles and Huberman analytic method. Results show that participants were involved in 12 different leisure activities on average. Compared to before the amputation, a decrease in participation was observed in all categories of leisure activity, and especially crafts, nature and outdoor activities, mechanics, sports and physical activities. Nonetheless, overall satisfaction was high. The most important constraints on participation in leisure were lack of accessibility, material considerations, functional abilities, affective constraints and social constraints. A decrease in leisure activity participation and the presence of constraints do not automatically translate into low levels of leisure satisfaction.

The Medici project consisted in archeological and paleopathological researches on some members of the great dynasty of the Italian Renaissance. The remains of Giovanni de' Medici, so-called "dalle Bande Nere" (Forlì 1498- Mantua 1526) have not been investigated yet. The enigma of the fatal injury and leg amputation of the famous Captain excited curiosity of paleopathologists, medical scientists and Italian Society of Orthopedic and Traumatology which contributed to realize the project of exhumation and study of his skeletal remains. The aim of the study is to report the first anthropological and paleopathological results. The tomb of Giovanni and his wife Maria Salviati was explored and the skeletal remains were investigated. Anthropological and paleopathological examination defined: age at death, physical constitution and activity, skeletal diseases. The bones of the leg were studied macroscopically, under stereoscopic microscope, at X-ray and CT scans to detect type of injury and level of amputation. The skeleton and muscular insertions of Giovanni revealed a young-adult and vigorous man, subjected to stresses of military activity since adolescence. Right tibia was amputated below the proximal half of diaphysis leaving long tibio-fibular stumps with a horizontal cut only at the lateral portion. Thus, the surgeon limited to complete the traumatic hemi-amputation. Amputation in the Sixteenth Century technically consisted in guillotine incisions below the knee using crescent shaped knife and bony saw, usually leaving a quite long tibial stump. Amputations in the Sixteenth Century were contaminated and grossly performed not providing vascular binding nor wound closure. The surgeon performed the procedure in conformity with surgical knowledge of that period.

They were recruited from inpatient and outpatient clinics of Jordan University hospital, Royal Farah Rehabilitation Center, and Al-basheer hospital in Amman, Jordan. Participants responded to a questionnaire that included a battery of questions requesting brief information about sociodemographic variables and characteristics of amputation. The level of depression and anxiety in each participating patient was assessed by the Hospital Anxiety and Depression Scale (HADS.Results: The prevalence of anxiety and depressive symptoms were 37% and 20%, respectively. Factors associated with high prevalence of psychological symptoms included female gender, lack of social support, unemployment, traumatic amputation, shorter time since amputation, and amputation below the knee. These findings were confirmed by a significant reduction of anxiety and depression scores in patients who received social support, patients with amputation due to disease, and patients with amputation above the knee. Presence of pain and use of prosthesis had no effect on the prevalence.Conclusions: The findings of the present study highlight the high incidence of psychiatric disability and

-extremity amputation (LEA) is a decisive factor behind post-operative outcomes (re-amputation/mortality) within three months after the first amputation. METHODS: In this retrospective cohort study, the independent sample t-test, Pearson's chi-squared test and a Cox proportional hazards model were used. RESULTS......: A total of 270 patients underwent non-traumatic LEA of whom 105 had diabetes, whereas 81 patients were included for this study. The mean age was 71 years (standard deviation: ± 11.8). Mortality was 27% and 16% were re-amputated within three months after their first amputation.The median pre-operative RBS...... level was 8.6 mmol/l (range: 4.6-18.7 mmol/l) with tertile ranges as follows: Q1 4.0-7.0 mmol/l; Q2 7.1-11.0 mmol/l; Q3 > 11.0 mmol/l. For the Q3 tertile, the age-adjusted hazard ratio for re-amputation was 0.77 (95% confidence interval (CI): 0.16-3.62) and for mortality it was 1.90 (95% CI: 0...

To assess the correlation between culture results of section's osseous slice biopsy (SOB) and the distal infected site responsible for the amputation performed concomitantly during major amputation of lower extremity. The influence of a positive culture of SOB on the patients' outcome was also evaluated. We conducted a retrospective study of medical charts of patients who underwent SOB during major amputation of lower extremity at our institution from 2000 to 2009. Fifty-seven patients (42 males/15 females, mean age 52.16years) who undergone major limb amputation (47 below knee and ten above knee) were included. The initial medical conditions of the investigated patients were: trauma (n=32), infection (n=13), trophic disorders (n=10) and tumor (n=2). The major cause of amputation was an uncontrolled infection, accouting for 64.9% of the cases (37/57) (foot=5, ankle=8, leg=24), the remaining 20 patients had trophic disorders of lower limb. Twenty-one (36.8%) from 57 biopsies were sterile, 12 (21.1%) doubtful and 24 (42.1%) positive. Thirty-one (54.4%) patients had an antibiotic-free interval before limb amputation. Independently of the bacterial species, 69.6% of the microorganisms identified from SOB were found in the distal infected site. Patients with positive SOB had a significantly longer interval between the decision to amputate the patient and the surgical procedure (200.2 vs. 70.1days; P<0.03) and a shorter total duration of antibiotic therapy before amputation than patients with negative SOB (3.68 vs. 6.08months; P<0.03). The delay for complete healing was significantly higher in patients with a positive SOB compared with those with a negative SOB (3.57 vs. 2.48months; P<0.03). Our results suggest that the infection may extend from the distal site to the level of amputation in a large proportion of cases and that the delay with which the amputation is performed after the decision has been taken may play a role in this event.

A recent article in the Dutch Journal of Medicine describes two cases of patients with body integrity identity disorder (BIID), a disorder in which patients might resort to self-amputation in order to create the body they wish for. The authors wonder if medical professionals should provide elective amputations in BIID patients in order to prevent them from harm and death. The amputation of a healthy limb in BIID in a medical context is currently under discussion. Doctors struggle to proceed to elective amputation of a healthy body part in BIID. An analogy with gender dysphoria or euthanasia might shed a different light on this dilemma.

Aim We aim to compare the outcome of diabetic patients with gangrenous toes who were managed initially either by digital amputation or by transmetatarsal amputation. The null hypothesis is that transmetatarsal amputation had less theatre trips and better healing. Materials and Methods A parallel observational comparative study of all diabetic patients who underwent either digital or transmetatarsal amputation in a tertiary referral center from 2002 through 2015. Comorbid conditions, subsequent amputations, hospital stay, and readmission were noted. Results A total of 223 patients underwent minor amputation during the study period, of which 147 patients were diabetic and 76 patients were non-diabetic. Seventy-seven patients had digital amputation and 70 transmetatarsal amputation in diabetic patients. Demographics were similar in both groups. The median time to major amputation was (400 ± IQR 1205 days) in the digital amputation group, compared to 690 ± IQR 891 days in the transmetatarsal amputation group ( P = 0.974). 29.9% of digital amputations and 15.7% of transmetatarsal amputations in diabetic patients, required minor amputations or revision procedures ( P = 0.04). Median length of hospital stay was (20 days, IQR 27) in the digital group and (17 days, IQR17) in the transmetatarsal amputation group ( P = 0.17). Need for re-admission was 48.1% in digital patients compared to 50% in transmetatarsal amputation patients ( P = 0.81). Quality of time spent without symptoms of disease or toxicity of treatment (Q-TWiST) was (315 days, IQR 45) in digital group and (346 days, IQR 48) in the transmetatarsal amputation patients ( P = 0.099). Conclusion Despite the lack of statistical significance, transmetatarsal amputation offered better outcome in the diabetic patients, with less re-intervention rate, shorter hospital stays, less theatre trips, and longer time without toxicity (TWiST).

[Desire for amputation in body integrity identity disorder].

Body integrity identity disorder (BIID) is a rare neuropsychiatric disorder in which patients experience a mismatch between the real and experienced body from childhood. BIID results in a strong desire to amputate or paralyse one or more limbs. We describe two BIID patients. A 40-year-old healthy male suffered daily from his desire for amputation, and therefore made a request for amputation at our academic medical centre. A 61-year-old male proceeded to self-amputation to create the body he had wished for, thereby curing himself from BIID. To date, no treatment has been found for BIID. Therefore patients often proceed to self-amputation, which could lead to serious and even dangerous complications. These case histories suggest that elective amputation may be a treatment for BIID. Many doctors, however, will question the admissibility of amputation of a healthy limb.

To assess patient satisfaction, functional and cosmetic outcomes of single-digit ray amputation in hand and identify factors that might affect the outcome. Forty-five patients who underwent ray amputation were evaluated, 37 males and eight females whose mean age was 36.6 years ranging between 15 and 67 years. Twenty-eight patients had dominant hand involvement. Twenty-one patients underwent primary ray amputation, and 24 patients had secondary ray amputation. Eight out of the 23 patients with central digit injuries underwent transposition. Grip strength, pinch strength, tactile sensibility and functional evaluation using Result Assessment Scale (RAS) and DASH score were analysed. Cosmetic assessment was performed using visual analogue scale (VAS) for cosmesis. Median time of assessment after surgery was 20 months. Average loss of grip strength and pinch strength was found to be 43.3 and 33.6%, respectively. Average RAS score was 3.75. Median DASH score was 23.4. Eighty-three percentage of patients had excellent or good cosmesis on the VAS. Transposition causes significant increase in DASH scores for central digit ray amputations but was cosmetically superior. Middle finger ray amputation had the maximum loss of grip strength, and index finger ray amputation had greater loss of pinch strength. Affection of neighbouring digits caused greater grip and pinch loss, and a higher DASH score. Primary ray resection decreased the total disability and eliminated the costs of a second procedure. Following ray amputation, one can predict an approximate 43.3% loss of grip strength and 33.6% loss of pinch strength. The patients can be counselled regarding the expected time off from work, amount of disability and complications after a single-digit ray amputation. Majority of the patients can return to the same occupation after a period of dedicated hand therapy. Therapeutic, Level III.

During four separate Israeli military attacks on Gaza (2006, 2009, 2012, and 2014), about 4000 Palestinians were killed and more than 17 000 injured (412 killed and 1264 injured in 2006; 1383 killed and more than 5300 injured in 2009; 130 killed and 1399 injured in 2012; and 2251 killed and 11 231 injured in 2014). An unknown number of people had traumatic amputations of one or more extremities. Use of unmanned Israeli drones for surveillance and armed attacks on Gaza was evident, but exact figures on numbers of drone strikes on Gaza are not available. The aim of this study was to explore the medical consequences of strikes on Gaza with different weapons, including drones. We studied a cohort of civilians in the Gaza Strip who had one of more traumatic limb amputation during the Israeli military attacks between 2006 and 2016. The study was done at The Artificial Limb and Polio Center (ALPC) in the Gaza Strip where most patients are treated and trained after amputation. We used standardised forms and validated instruments to record date and mechanism of injury, self-assessed health, socioeconomic status, anatomical location and length of amputation, comorbidity, and the results of a detailed clinical examination. The studied cohort consisted of 254 Paletinian civilians (234 [92%] men, 20 [8%] women, and 43 [17%] children aged 18 years and younger) with traumatic amputations caused by different weapons. 216 (85%) people had amputations proximal to wrist or ankle, 131 (52%) patients had more than one major amputation or an amputation above the knee, or both, and 136 (54%) people were injured in attacks with Israeli drones, including eight (40%) of the women. The most severe amputations were caused by drone attacks (p=0·0001). Extremity injuries after drone attacks led to immediate amputation more often than with other weapons (p=0·014). Patients injured during cease-fire periods were younger than patients injured during periods of declared Israeli military

Amputation rehabilitation and prosthetic restoration. From surgery to community reintegration.

Esquenazi, Alberto

The purpose of this review is to summarize the literature related to the advances that have taken place in the management and rehabilitation care of limb amputation. Prostheses for the lower and upper limb amputee have changed greatly over the past several years, with advances in components, socket fabrication and fitting techniques, suspension systems and sources of power and electronic controls. Higher levels of limb amputation can now be fitted with functional prostheses, which allow more patients to achieve independent life styles. This is of particular importance for the multi-limb amputee. The rehabilitation of more traditional lower limb levels of amputation have also greatly benefited from the technological advances including energy storing feet, electronic control hydraulic knees, ankle rotators and shock absorbers to mention a few. For the upper limb amputee, myoelectric and proportional controlled terminal devices and elbow joints are now used routinely in some rehabilitation facilities. Experimental prosthetic fitting techniques and devices such as the use of osseo-implantation for suspension of the prosthesis, tension control hands or electromagnetic fluids for knee movement control will also be briefly discussed in this paper. It is possible to conclude from this review that many advances have occurred that have greatly impacted the functional outcomes of patients with limb amputation.

The treatment strategy for diabetic foot syndrome must take into account protective sensibility of the foot, open wounds, infection status, and the rules of septic bone surgery. Interventions are classified as elective, prophylactic, curative, or emergency. Amputations in the forefoot and midfoot region are performed as ray amputations (including metatarsal), which can often be carried out as "inner" amputations. Gentle tissue treatment mandatory because of greater risk of revision with re-amputation compared to classical amputation. Good demarcation of infection, acute osteomyelitis, osteolytic lesions, neurotropic ulcer, arterial and venous blood flow to the other toes, gangrene of other toes with metatarsal affection. Arterial occlusive disease, infection of neighboring areas, avoidable amputations, poorly healing ulcers on the lower leg. Primary dorsal approach; minimal incisional distance (5 cm) to minimize skin necrosis risk. Atraumatic preparation, minimize hemostasis to not compromise the borderline perfusion situation. In amputations, plantar skin preparation and longer seams placed as dorsal as possible, either disarticulated and maintain cartilage, or round the cortical metatarsal bone after resection. Diabetes control. Braun splint, mobilization in a shoe with forefoot decompression and hindfoot support, physiotherapy. Antibiotics based on resistance testing. If no complications, dressing change on postoperative day 1. Optimal wound drainage by lowering foot several times a day; drainage removal after 12-24 h. Insoles and footwear optimization. Amputations require continued attention and if necessary treatment to avoid sequelae. Insufficient treatment associated with recurrent ulceration and altered anatomy.

The heterogeneity of medical complications that lead to amputation has resulted in a diverse patient population with differing rehabilitation needs; however, the rehabilitation trends for patients with lower extremity amputations across Canada have not been studied previously. To describe trends in rehabilitation after lower extremity amputations and the factors affecting rehabilitation length of stay in Canada. Retrospective cohort analysis. Canadian inpatient rehabilitation facilities that received persons with lower extremity amputations discharged from academic or community hospitals. Patients underwent lower extremity amputations between 2006 and 2009 for nontraumatic indications and were then discharged to a rehabilitation facility. Patients were identified from the Canadian Institute for Health Information's Discharge Abstract Database that includes hospital admissions across Canada except Quebec. Inpatient rehabilitation after lower extremity amputations. Length of stay, discharge destination, and change in total and motor function scores. The analysis included 5342 persons who underwent lower extremity amputations, 1904 of whom were transferred to a rehabilitation facility (36%). Patients most commonly underwent single below-knee (74%) and above-knee (17%) amputations. The duration of rehabilitation varied by whether the amputation was performed by a vascular (median = 36 days), orthopedic (median = 38 days), or general surgeon (median = 35 days). The overall median length of stay was 36 days. Most patients (72%) subsequently were discharged home and 9% were readmitted to hospital. Predictors of longer rehabilitation included amputation by an orthopedic surgeon (beta = 5.0, P ≤ .01), older age (beta = 0.2, P ≤ .01), and a history of ischemic heart disease (beta = 3.8, P = .03) or congestive heart failure (beta = 5, P = .04). Patients who spent Canada after lower extremity amputation varies by the type of surgeon performing the amputation. Advanced age

In this article, a comparison of replantation using microsurgical replantation (replantation) and the Brent method and its modification (pocket principle) in the treatment of fingertip amputation is reported. As a classification of amputation level, we used Ishikawa's subzone classification of fingertip amputation, and the cases of amputations only in subzone 2 were included in this study. Between these two groups, there was no statistical difference in survival rate, postoperative atrophy, or postoperative range of motion. In terms of sensory recovery, some records were lost and exact study was difficult. But there was no obvious difference between these cases. In our comparison of microsurgical replantation versus the pocket principle in treatment of subzone 2 fingertip amputation, there was no difference in postoperative results. Each method has pros and cons, and the surgeon should choose which technique to use based on his or her understanding of the characteristics of both methods.

2017-09-01

Guillotine amputation for diabetic foot sepsis followed by an elective refashioning of the stump is regarded as standard practice. Primary amputation is associated with higher reamputation rates. A prospective cohort study of 85 patients who underwent surgery for diabetic foot sepsis from 2014 to 2016 at Madadeni Provincial Hospital, KwaZulu-Natal was done. Ethical approval was granted. The Wagner classification (Wag) was used to classify disease severity. Outcome measures included length of hospital stay, mortality and re-amputation rates. Of the 85 patients, females (n=45) accounted for 53% of admissions. The mean age was 61 years (range: 29 to 80 years). The majority of patients were African, n=75 (88%). Only 1 patient presented with diabetic ketoacidosis and 18 (21%) presented with renal failure. Most patients presented with advanced disease: [Wag 5, n=66 (78%); Wag 4, n=12 (14%); Wag 3, n=5 (6%); Wag 2, n=2 (2%)]. The levels of vascular occlusion included aortoiliac disease n=2 (2%), femoro-popliteal disease n=18 (21%), tibio-peroneal disease n=65 (76%). Radiographic features included normal findings n=60 (71%); gas gangrene n=11 (13%), osteitis n=8 (9%). The following amputations were done: AKA, n=29 (34%); BKA, n=39 (46%); TMA, n=8 (9%); Toe-ectomy, n=5 (6%) and Debridement, n=4 (5%). The re-amputation rate to above knee amputation was n= 3/39 (8%). All AKA stumps healed well. The overall in-hospital mortality was n=5 (6%) and mean length of hospital stay was 7.8 days ±3.83. The majority of patients presented with advanced disease requiring a major amputation. A definitive one stage primary amputation is a safe and effective procedure for diabetic foot sepsis and is associated with a low re-amputation rate, length of hospital stay and mortality. A guillotine amputation should be reserved for physiologically unstable patients.

We have previously reported the importance of adequate and precise arterial anastomosis and the hypothesis that, up to subzone III, fingertip amputation salvage can be achieved on arterial anastomosis alone. These findings were reported during the meeting of the Japanese Society of Reconstructive Microsurgery. This is our follow-up report with insight and opinion on the limitations of complete fingertip amputation salvage on arterial anastomosis alone. We examined 67 fingers (59 patients) with fingertip amputations presenting to our hospital between January 2005 and December 2008. Amputation levels and whether these injuries received only arterial or both arterial and venous anastomoses were noted. Fisher exact test was used to examine statistical differences between the groups. Amputation levels were 11 in subzone I, 20 in subzone II, 17 in subzone III, and 19 in subzone IV. Successful replantation was achieved in 87% (58 of 67) of fingers. There was no statistically significant difference between fingers receiving arterial alone versus both anastomoses in amputations of subzones I, II, and III. We found that with proper postoperative congestion care, no statistically significant difference in replantation success of fingers receiving arterial anastomosis alone versus both arterial and venous were noted up to subzone III. However, in subzone IV, regardless of the postoperative congestion, compete necrosis rates are high; thus, it is speculated that a venous anastomosis is necessary for successful replantation. It is preferable to perform as many anastomoses as possible, but we believe that it is also desirable for the procedure to be fast and less invasive. In cases that have no adequate vein, fingertip replantation can be achieved on arterial anastomosis alone up to subzone III.

Full Text Available Background. A decision to replant is critically dependent on the condition of the amputated digit and the way it was preserved during transport. The most common error is exposing the amputated digit to very low temperatures. Preservation directly on ice, on cooling devices in portable refrigerators, or on top of packets of frozen meat often result in a frozen and therefore unusable body digit.Methods. An inquiry questionnaire on correct methods of preservation of amputated digits was conducted on a sample of 30 lay persons, 30 medical students, and 15 physicians.Three simulations of most frequently used methods of preservation of amputated digit were conducted (the correct method; directly on ice; on cooling devices of portable refrigerators. Environment temperature of the (simulated amputated digits stored was measured.In a retrospective study, hospital records of patients treated at the Clinical department of plastic surgery and burns in Ljubljana between 1998 and 2002 were examined. We determined the number of replantations performed, gender of the patients, their age, the mechanism of the injury, the success rate of the replantation, and the duration of hospitalisation. In five case described in detail, we present an inadequate treatment of the amputated digits.Results. The results of the questionnaire survey show that no less than 86.7% of lay person respondents would have treated the injuries in an incorrect way; same holds for 43.4% students of medicine, and 33.3% of practicing physicians.The temperature of the simulated amputated digit remained above 5°C throughout the simulated correct treatment. When preserved directly on ice on or coolant bodies, the temperature dropped below the freezing point and never climbed above 0°C throughout the duration of the simulation (150 minutes.Between years 1998 and 2002, Clinical department of plastic surgery and burns at the University clinical centre Ljubljana admitted 124 injured persons with

The aim of this retrospective study was to evaluate factors potentially influencing short- and long-term mortality in patients who had a non-traumatic lower limb amputation in a university hospital. A consecutive series of 93 amputations (16% toe/foot, 33% trans-tibial, 9% through knee and 42......% trans-femoral) were studied. Their mean age was 75.8 years; 21 (23%) were admitted from a nursing home and 87 (92%) were amputated due to a vascular disease and/or diabetes. Thirty days and 1-year mortality were 30 and 54%, respectively. Cox regression analysis demonstrated that the 30-day mortality...... was associated with older age (P = 0.01), and the number of co-morbidities (P = 0.04), when adjusted for gender, previous amputations, cause of and amputation level, and residential status. Thus, a patient with 4 or 5 co-morbidities (n = 20) was seven times more likely to die within 30 days, compared...

There are many options in the management of fingertip or finger amputations. Injudicious revision amputation may cause complications. These complications can be prevented by tension-free closure of the amputation stump or primary coverage with appropriate flap. Replantation is the best way to keep the original length and maintain digital function. Patent vein repair or venous drainage with bleeding until neovascularization to the replanted part is the key to successful replantation. Prevention and management of complications in replantation and revision amputation increase patients' satisfaction and decrease costs. Research is needed to define new indications of replantation for digital amputation. Copyright © 2015 Elsevier Inc. All rights reserved.

2011-09-01

To retrospectively analyze the reasons for reoperations following primary nonconstrained proximal interphalangeal (PIP) joint arthroplasty and review clinical outcomes in this group of patients with 1 or more reoperations. Between 2001 and 2009, 294 nonconstrained (203 pyrocarbon and 91 metal-plastic) PIP joint replacements were performed in our institution. A total of 76 fingers (59 patients) required reoperation (50 pyrocarbon and 26 metal-plastic). There were 40 women and 19 men with an average age of 51 years (range, 19-83 y). Primary diagnoses included osteoarthritis in 35, posttraumatic arthritis in 24, and inflammatory arthritis in 17 patients. There were 21 index, 27 middle, 18 ring, and 10 small fingers. The average number of reoperations per PIP joint was 1.6 (range, 1-4). A total of 45 joints had 1 reoperation, 19 had 2, 11 had 3, and 1 had 4. Extensor mechanism dysfunction was the most common reason for reoperation; it involved 51 of 76 fingers and was associated with Chamay or tendon-reflecting surgical approaches. Additional etiologies included component loosening in 17, collateral ligament failure in 10, and volar plate contracture in 8 cases. Inflammatory arthritis was associated with collateral ligament failure. Six fingers were eventually amputated, 9 had PIP joint arthrodeses, and 2 had resection arthroplasties. The arthrodesis and amputation rates correlated with the increased number of reoperations per finger. Clinically, most patients had no or mild pain at the most recent follow-up, and the PIP joint range-of-motion was not significantly different from preoperative values. Pain levels improved with longer follow-up. Reoperations following primary nonconstrained PIP joint arthroplasties are common. Extensor mechanism dysfunction was the most common reason for reoperation. The average reoperation rate was 1.6, and arthrodesis and amputation are associated with an increasing number of operations. Overall clinical outcomes demonstrated no

2017-01-01

Full Text Available Introduction: The phantom limb pain (PLP and phantom limb sensation (PLS are very common among amputated cancer patients, and they lead to considerable morbidity. In spite of this, there is a lack of epidemiological data of this phenomenon among the Asian population. This study was done to provide the data from Indian population. Methods: The prevalence of PLP, stump pain (SP, and PLS was prospectively analyzed from the amputated cancer patients over a period of 2 years in Dr. B.R.A. Institute Rotary Cancer Hospital, All India Institute of Medical Sciences, New Delhi. The risk factors and the impact of phantom phenomenon on patients were also noted. Results: The prevalence of PLP was 41% at 3 and 12 months and 45.3% at 6 months, whereas that of SP and PLS was 14.4% and 71.2% at 3 months, 18.75% and 37.1% at 6 months, 15.8% and 32.4% at 12 months, respectively. There was higher prevalence of PLP and PLS among the patients with history of preamputation pain, smoking with proximal level of amputation, receiving general anesthesia, receiving intravenous (IV opioid postoperative analgesia, and developing neuroma or infection. Conclusion: The prevalence of PLP and PLS was higher among the cancer amputees as compared to SP, and a few risk factors responsible for their higher prevalence were found in our study. The PLP and PLS lead to considerable morbidity in terms of sleep disturbance and depression.

Vedung, S.; Arturson, G.; Hedlund, A.; Wadin, K.

1990-01-01

Because it is difficult to estimate the extent of deep tissue injury clinically, angiography was carried out in 28 patients with signs of damage from current flow through the body. Eight of the arteriograms showed normal extremities, 6 showed changes of small arteries, and 38 showed injury to the main arteries. In the latter group there were 24 total arterial occlusions, narrow irregular lumens in 10, and 4 had occlusion and distal refilling. Changes in the main arteries were most often seen near major joints where the internal body resistance as well as the density of the current are higher. Injury to the main arteries resulted in severe neuromuscular damage or amputation of the limb, whereas injury to small arteries resulted in little functional deficit. Of the 25 amputations 19 were at the level of the arterial occlusion. Spasmolytic drugs did not increase filling. We concluded that early angiography is valuable for the detection of deep injury and often indicates the level of adequate amputation or the need for immediate exploration. In some patients it indicated the necessity for arterial reconstruction. (au)

First suggested by Brent in 1979, the pocket principle is an alternative method for patients for whom a microsurgical replantation is not feasible. We report the successful results of a modified palmar pocket method in adults. Between 2004 and 2008, we treated 10 patients by nonmicrosurgical replantation using palmar pocketing. All patients were adults who sustained a complete fingertip amputation from the tip to lunula in a digits. In all of these patients, the amputation occurred due to a crush or avulsion-type injury, and a microsurgical replantation was not feasible. We used the palmar pocketing method following a composite graft in these patients and prepared the pocket in the subcutaneous layer of the ipsilateral palm. Of a total of 10 cases, nine had complete survival of the replantation and one had 20% partial necrosis. All of the cases were managed to conserve the fingernails, which led to acceptable cosmetic results. A composite graft and palmar pocketing in adult cases of fingertip injury constitute a simple, reliable operation for digital amputation extending from the tip to the lunula. These methods had satisfactory results.

The incidence of lower limb amputation is high across the globe and continues to be a major threat to morbidity and mortality. Consequently, the provision of high quality and effective prosthetics services have been known as an essential component for a successful rehabilitation outcome. In Malaysia, amputation prevalence has been increasing in which several main components of service delivering aspects (such as service intervention, prosthetic personnel) should be anticipated to accommodate for the increasing demand. This article highlights the hurdles experienced in providing prosthetic services in Malaysia from multiple aspects such as financial burden to acquire the prosthesis and lack of expertise to produce quality prosthesis. This paramount issues consequently justify for the urgency to carry out national level survey on the current statistics of lower limb amputation and to ascertain the available workforce to provide a quality prosthetics services. Only with accurate and current information from the national survey, strategies and policies aimed at enhancing the outcome from prosthetics services can be achieved. PMID:29386978

Full Text Available Background: Even though replantation surgery has now become a routine procedure, it remains delicate and demanding surgery, requiring adequate training and expertise in microsurgical techniques. Functional outcomes following replantation vary with the level of injury. Replants of the fingers distal to the flexor superficial are insertion, the hand at the wrist, and the upper extremity at the distal forearm can achieve good function. With the advent of refined microscopes, sutures, and needles, along with specialized surgical training, replantation has become a routine part of hand-surgery practice in centers all over the world. Clearly, survival does not equate with function. Amputations constitute multisystem injury, with disruption of skeletal support (bone, motor function (muscle, sensibility (nerve, circulation (blood vessel, and soft-tissue coverage (skin. A lot of News work-related accidents published daily. Complete amputation of the palm with sharp objects electric disrupts quality of life and irreversible effects on their life. Replantation or repair the damaged organ can improve their quality of life, functional body. Case presentation: The case is a man with complete amputation of the palm while working with an electrical machine, at the same time as damage and severe crush was also the distal phalanx of the first finger of the right hand. Patient was admitted to the emergency unit at Fatemi Hospital of Ardabil city in January 2014, Iran, and underwent to surgery for replantation. Conclusion: Complete amputation of palm and its successful replantation are among rarely occurred and reportable cases. Complete amputation of palm and successful replantation and the 10-month follow-up indicated that the patient had a successful operation. No abnormalities were found in the blood circulation, and finger grasping was acceptable. Nerve development was acceptable.

Chronic Low Back Pain in Individuals with Lower-limb Amputation

Full Text Available Low back pain (LBP is a common condition in individuals which experienced psychology and physical trauma. LBP is usually found in persons with lower-limb amputation (LLA, as the most common sign of somatisation or inappropriately made prostheses. Our goal was to investigate cases of chronic pain syndrome in persons with LLA and to determine factors, which influence their functional inability due to LBP. Pain after LLA has been studied. 37 persons, including 26 war veterans (70.2 % and 11 (29.8 % civilians with LLA due to an illness, were examined. All participants gave their informed consent and filled Oswestry index of disability due to chronic LBP, divided into 10 sections with 6 questions each, with marks in the range 0-5. The average age of 37 analyzed participants with LLA was 46.2+-10.92 years. 30 participants (81.1 % were married, 4 (10.8 % were single and 3 (8.1 % were widows. 27 (73.0 % participants had below the knee amputation, 5 (13.5 % had above the knee amputation and 5 (13.5 % had foot amputation. 33 (89.6 % participants experienced chronic LBP in the last 2-10 years and 4 (10.8 % did not have pains. According to Oswestry index for chronic pain higher level of social functionality was found in civilian amputees than in war veterans (p<0.05. Married civilian amputees have higher level of disability during seating (p<0.01, sleeping (p<0.01 and traveling (p<0.05. Higher level of social disorder among civilian amputees is due to the fact that they belong to older group of participants which usually have social integration at the lower degree. More serious problems during seating, traveling and sleeping among this group are probably due to co morbidity. Chronic LBP was found among 89.6 % of the participants. Higher level of social disorder, problems during seating, traveling and sleeping were identified in the civilian amputees and the married participants.

Marcelo Teodoro Ezequiel Guerra

Full Text Available ABSTRACT OBJECTIVE: To compare serum 25-hydroxyvitamin D (25[OH]D levels, a serum marker of vitamin D3, between patients with and without proximal hip fracture. METHODS: This was a case-control study in which serum samples of 25(OHD were obtained from 110 proximal hip fracture inpatients and 231 control patients without fractures, all over 60 years of age. Levels of 25(OHD lower than or equal to 20 ng/mL were considered deficient; from 21 ng/mL to 29 ng/mL, insufficient; and above 30 ng/mL, sufficient. Sex, age, and ethnicity were considered for association with the study groups and 25(OHD levels. RESULTS: Patients with proximal hip fracture had significantly lower serum 25(OHD levels (21.07 ng/mL than controls (28.59 ng/mL; p = 0.000. Among patients with proximal hip fracture, 54.5% had deficient 25(OHD levels, 27.2% had insufficient levels, and only 18.2% had sufficient levels. In the control group, 30.3% of patients had deficient 25(OHD levels, 30.7% had insufficient levels, and 38.9% had sufficient levels. Female patients had decreased serum 25(OHD levels both in the fracture group and in the control group (19.50 ng/mL vs. 26.94 ng/mL; p = 0.000 when compared with male patients with and without fracture (25.67 ng/mL vs. 33.74 ng/mL; p = 0.017. Regarding age, there was a significant association between 25(OHD levels and risk of fracture only for the age groups 71-75 years and above 80 years. CONCLUSION: Patients with proximal hip fracture had significantly decreased serum 25(OHD levels when compared with the control group. Female patients had significantly lower serum 25(OHD levels in both groups.

Genetic material for polymerase chain reaction (PCR) and Southern blot analysis on transgenic mice is normally obtained by tail biopsy. Additionally, it may be necessary to tattoo the mice, as it is essential to have a good and permanent identification. The aim of this study was to evaluate the effects of amputating the tip of the tail to obtain a biopsy for genetic analysis and of ink tattooing on welfare in C57BL/6J mice, a strain often used as genetic background for transgenes. The behaviour of the animals, fluctuating asymmetry (FA, a measure of developmental instability) and the level of restitution in the remaining part of the tail were evaluated and used for an assessment of the impact of these procedures on the welfare of the animals. One group of mice was marked by tail tattooing at various ages. Another group of mice were tail amputated at 12 or 20 days of age. Body weight and FA were followed, and at the end of the experiment, the level of fear/anxiety was assessed using a light-dark box. In the group of tail-amputated animals observation of climbing behaviour and a beam walking test for balance was performed. Seven weeks after tail amputation, the animals were euthanized. The remaining part of the tail was evaluated histopathologically. Body weight, behaviour in the light-dark box and balance test results were not influenced by tail amputation or tattooing. FA was only transiently increased by tattooing. Climbing behaviour was reduced just after tail amputation at 20 days of age. No signs of neuromas were found in the amputated tails, but seven weeks after amputation a significant number of mice did not have fully regenerated glandular tissue and hair follicles in the tail. It is concluded that both tail amputation and tail tattooing seem to have minor short-term negative effects on welfare and that the tissues on the tail probably do not regenerate fully after amputation.

Vascular calcification is established to be a critical factor in diabetes mellitus, which causes cardiovascular and amputation complication of diabetic patients. OPG/RANKL/RANK axis serves as a regulatory role in vascular calcification. Ghrelin, an endogenous ligand of growth hormone secretagogue receptor (GHSR), has been reported to exhibit potent cardiovascular protective effects. However, the role of ghrelin in the regulation of diabetic vascular calcification is still elusive. Here, we reported the role of ghrelin and its relationship with OPG/RANKL/RANK system in patients with diabetic foot amputation. In vivo and in vitro investigations were performed. Sixty type 2 diabetic patients with foot amputation were enrolled in vivo investigation, and they were divided into three groups through Doppler ultrasound: mild stenosis group (n=20), moderate stenosis group (n=20), and severe stenosis/occlusion group (n=20). Morphological analysis results showed diffused calcium depositions in the anterior tibial artery of diabetic amputees. Compared with the mild and moderate stenosis group, the severe stenosis/occlusion group had more spotty calcium depositions in atherosclerotic plaques. Western blot analysis indicated the expressions of osteoprotegerin (OPG) and ghrelin were downregulated, while the expression of receptor activator of nuclear factor kappa B ligand (RANKL) was upregulated with the vascular stenosis aggravation. Pearson correlation analysis revealed a negative correlation between calcium content and ghrelin levels (r=-0.58, Pghrelin levels and sRANKL levels (r=-0.57, Pghrelin levels (r=0.63, PGhrelin blunted calcification in a dose-dependent manner. In addition, ghrelin upregulated OPG expression and downregulated RANKL expression in VSMC calcification when anti-OPG antibody and RANKL were performed. Collectively, we therefore conclude serum ghrelin level may be a predictor of diabetic vascular calcification. The possible mechanism may be related with OPG

Full Text Available Penile amputation is an uncommon urological emergency. Although rare, traumatic amputation of penis is a challenging injury to treat. However, modern microsurgical reconstruction techniques have improved success rate of penile replantation and become the procedure of choice for managing these patients. Herein, we report on a case of penile amputation following an industrial accident.

Increased slow transport in axons of regenerating newt limbs after a nerve conditioning lesion made prior to amputation

International Nuclear Information System (INIS)

Maier, C.E.

1989-01-01

The first part of this study shows that axonal density is constant in the limb stump of the next proximal to the area of traumatic nerve degeneration caused by limb amputation. The results of the second part of this work reveal that a nerve conditioning lesion made two weeks prior to amputation is associated with accelerated limb regeneration and that this accelerated limb regeneration is accompanied by an earlier arrival of axons. This is the first demonstration of naturally occurring limb regeneration being enhanced. In this study SCb cytoskeletal proteins were identified and measured using SDS-PAGE and liquid scintillation counting. Proteins were measured at 7, 14, 21, and 28 days after 35 S-methionine injection and the normal rate of SCb transport determined to be 0.19 mm/day. A single axotomy does not enhance the rate of SCb transport but does increase the amount of labeled SCb proteins that are transported. When a conditioning lesion is employed prior to limb amputation and SCb proteins are measured at 7, 14, and 21 days after injection, there is a twofold acceleration in the rate of SCb transport and an increase in the amount of SCb proteins transported in conditioned axons

Questionnaire was in the scores on the Job Satisfiers content scale, with the amputees scoring better than the patients treated with lengthening (p=0.015). The American Academy of Orthopaedic Surgeons Lower Limb Module did not demonstrate differences in health-related quality of life or physical function. The patients who were treated with lengthening had started out with more residual foot rays and more fibular preservation than the amputees. They also required more surgical intervention than did those with an amputation. While patients with an amputation spent less of their childhood undergoing treatment, they were found to have a better outcome in terms of only one of seventeen quality-of-life parameters. Both groups of patients who had had treatment of fibular deficiency were functioning at high levels, with an average to above-average quality of life compared with that of the normal adult population.

An enhanced treatment program with markedly reduced mortality after a transtibial or higher non-traumatic lower extremity amputation

Background and purpose - Historically, high 30-day and 1-year mortality post-amputation rates (> 30% and 50%, respectively) have been reported in patients with a transtibial or higher non-traumatic lower extremity amputation (LEA). We evaluated whether allocating experienced staff and implementing...... adjusted for age, sex, residential and health status, the disease that caused the amputation, and the index amputation level showed that 30-day and 1-year mortality risk was reduced by 52% (HR =0.48, 95% CI: 0.25-0.91) and by 46% (HR =0.54, 95% CI: 0.35-0.86), respectively, in the intervention group...

People with transradial hand amputations who own a myoelectric prosthesis currently have some control capabilities via sEMG. However, the control systems are still limited and not natural. The Ninapro project is aiming at helping the scientific community to overcome these limits through the creation of publicly available electromyography data sources to develop and test machine learning algorithms. In this paper we describe the movement classification results gained from three subjects with an homogeneous level of amputation, and we compare them with the results of 40 intact subjects. The number of considered subjects can seem small at first sight, but it is not considering the literature of the field (which has to face the difficulty of recruiting trans-radial hand amputated subjects). The classification is performed with four different classifiers and the obtained balanced classification rates are up to 58.6% on 50 movements, which is an excellent result compared to the current literature. Successively, for each subject we find a subset of up to 9 highly independent movements, (defined as movements that can be distinguished with more than 90% accuracy), which is a deeply innovative step in literature. The natural control of a robotic hand in so many movements could lead to an immediate progress in robotic hand prosthetics and it could deeply change the quality of life of amputated subjects.

Locomotor adaptation enables walkers to modify strategies when faced with challenging walking conditions. While a variety of neurological injuries can impair locomotor adaptability, the effect of a lower extremity amputation on adaptability is poorly understood. Determine if locomotor adaptability is impaired in persons with unilateral transtibial amputation (TTA). The locomotor adaptability of 10 persons with a TTA and 8 persons without an amputation was tested while walking on a split-belt treadmill with the parallel belts running at the same (tied) or different (split) speeds. In the split condition, participants walked for 15 minutes with the respective belts moving at 0.5 m/s and 1.5 m/s. Temporal spatial symmetry measures were used to evaluate reactive accommodations to the perturbation, and the adaptive/de-adaptive response. Persons with TTA and the reference group of persons without amputation both demonstrated highly symmetric walking at baseline. During the split adaptation and tied post-adaptation walking both groups responded with the expected reactive accommodations. Likewise, adaptive and de-adaptive responses were observed. The magnitude and rate of change in the adaptive and de-adaptive responses were similar for persons with TTA and those without an amputation. Furthermore, adaptability was no different based on belt assignment for the prosthetic limb during split adaptation walking. Reactive changes and locomotor adaptation in response to a challenging and novel walking condition were similar in persons with TTA to those without an amputation. Results suggest persons with TTA have the capacity to modify locomotor strategies to meet the demands of most walking conditions despite challenges imposed by an amputation and use of a prosthetic limb.

[Body integrity identity disorder, relief after amputation].

Blom, R M; Braam, A W; de Boer-Kreeft, N; Sonnen, M P A M

2014-01-01

Body integrity identity disorder (BIID) is a rare condition in which a person, for no apparent physical reason, is tormented by the experience that a body-part, such as a limb, does not really belong to the body. Patients experience an intense desire for the limb to be amputated (a 'desire' formerly referred to as 'apotemnophilia'). We report on a 58-year-old male patient with BIID who froze one of his legs so that he could amputate it himself. A surgeon ultimately intervened and amputated the leg professionally. The patient was extremely relieved and was still experiencing relief at a follow-up three years later.

CT scanning in patients with amputated legs

CT scanning after above-knee amputation and below-knee amputation helps to determine the calcium salt content of the examined bones, and to differentiate changes in the surrounding soft parts. By comaring the sides, it is quite easy to detect osteoporotic changes shortly after amputation which would otherwise remain undetected by X-ray film examination. It is equally easy to verify muscular changes, whereas characteristic changes in density allow to determine the share of vacant fat in muscular atrophy. Initial examinations proved the usefulness of CT diagnosis for early detection of dystrophic osseous and muscular changes and also show the possibilities of early therapy control of dystrophy treatment.

Karam, Matthew D; Willey, Michael; Shurr, Donald G

2010-01-01

Total knee replacement (TKR) is reserved for patients with severe and disabling arthritis that is non-responsive to conservative measures. Based on existing data, total knee replacement is a safe and cost-effective treatment for alleviating pain and improving physical function in patients who do not respond to conservative therapy. Despite the large variation in health status of patients and types of prosthesis implanted, total knee replacement has proven to be a relatively low risk and successful operation. Each year in the United States surgeons perform approximately 300,000 TKR.1 Likewise, lower extremity amputation is commonly performed in the United States with an annual incidence of 110,000 per year.2 Nearly 70% of all lower extremity amputations are performed as the result of chronic vascular disease, followed by trauma (22%), congenital etiology and tumor (4% each).3 Approximately 50% of all lower extremity amputations are performed secondary to complications from Diabetes Mellitus. Norvell et al. demonstrated that patients who have previously undergone transtibial amputation and ambulate with a prosthesis are more likely to develop degenerative joint disease in the con-tralateral extremity than the ipsilateral extremity.4 Further, radiographic changes consistent with osteoporosis have been demonstrated in up to 88% of limbs that have undergone transtibial amputation.8 To our knowledge, there have been only three reported cases of total knee replacement in patients with ipsilateral transtibial amputation.5,7 The purpose of the present study is to review the existing data on total knee replacement in patients who have undergone transtibial amputation. Further we present a patient with a transtibial amputation who underwent contralateral total knee replacement. PMID:21045987

Synostosis of proximal phalangeal bases for loss of distal metacarpal

Directory of Open Access Journals (Sweden)

Pankaj Jindal

2016-01-01

Full Text Available A finger rendered unstable due to loss of metacarpal head can be stabilized by creating a synostosis at the base of the proximal phalanx of the affected finger with the adjacent normal finger. A cortico cancellous graft bridges the two adjacent proximal phalanges at their bases which are temporarily stabilized with an external fixator. The procedure can be done for, recurrence of giant cell tumor of metacarpal and for traumatic metacarpal loss. The procedure and long term follow up of one patient is presented who had giant cell tumor. This option should be considered before offering ray amputation. There is no micro vascular surgery involved, nor is there any donor site morbidity. The graft heals well without any absorption. The affected finger shows excellent function in the long term followup.

There is a paucity of information regarding sexual functioning in persons with lower extremity amputations. The purpose of this study was to describe sexual and psychological functioning and health status in persons with lower extremity amputation. Self-report surveys assessed sexual functioning (Derogatis Inventory), depression (Beck Depression Inventory, anxiety (State-Trait Anxiety Inventory), and health status (Health Status Questionnaire) in a convenience sample of 30 men with lower extremity amputations. Mean age of the participants was 57 years (range 32-79). Mean duration since amputation was 23 months (range 3-634 months). Twenty one subjects (70%) had trans-tibial and seven subjects (23%) had trans-femoral amputations. A majority of subjects were experiencing problems in several domains of sexual functioning. Fifty three percent (n = 16) of the subjects were engaged in sexual intercourse or oral sex at least once a month. Twenty seven percent (n = 8) were masturbating at least once a month. Nineteen subjects (63%) reported orgasmic problems and 67% were experiencing erectile difficulties. Despite these problems, interest in sex was high in over 90% of the subjects. There was no evidence of increased prevalence of depression or anxiety in these subjects when compared to other outpatient adult populations. Sexual problems were common in the subjects studied. Despite these problems, interest in sex remained high. Few investigations have been directed toward identifying the psychological and social factors that may contribute to these problems and more research with a larger population is needed in this area.

Tibial rotational osteotomy for idiopathic torsion. A comparison of the proximal and distal osteotomy levels.

Science.gov (United States)

Krengel, W F; Staheli, L T

1992-10-01

A retrospective analysis was done of 52 rotational tibial osteotomies (RTOs) performed on 35 patients with severe idiopathic tibial torsion. Thirty-nine osteotomies were performed at the proximal or midtibial level. Thirteen were performed at the distal tibial level with a technique previously described by one of the authors. Serious complications occurred in five (13%) of the proximal and in none of the distal RTOs. For severe and persisting idiopathic tibial torsion, the authors recommend correction by RTO at the distal level. Proximal level osteotomy is indicated only when a varus or valgus deformity required concurrent correction.

2012-05-01

To observe the effectiveness of vacuum sealing drainage (VSD) combined with anti-taken skin graft on open amputation wound by comparing with direct anti-taken skin graft. Between March 2005 and June 2010, 60 cases of amputation wounds for limbs open fractures were selected by using the random single-blind method. The amputation wounds were treated with VSD combined with anti-taken skin graft (test group, n = 30) and direct anti-taken skin graft (control group, n = 30). No significant difference was found in age, gender, injury cause, amputation level, defect size, preoperative albumin index, or injury time between 2 groups (P > 0.05). In test group, the redundant stump skin was used to prepare reattached staggered-meshed middle-thickness skin flap by using a drum dermatome dealing after amputation, which was transplanted amputation wounds, and then the skin surface was covered with VSD for continuous negative pressure drainage for 7-10 days. In control group, wounds were covered by anti-taken thickness skin flap directly after amputation, and conventional dress changing was given. To observe the survival condition of the skin graft in test group, the VSD device was removed at 8 days after operation. The skin graft survival rate, wound infection rate, reamputation rate, times of dressing change, and the hospitalization days in test group were significantly better than those in control group [ 90.0% vs. 63.3%, 3.3% vs. 20.0%, 0 vs. 13.3%, (2.0 +/- 0.5) times vs. (8.0 +/- 1.5) times, and (12.0 +/- 2.6) days vs. (18.0 +/- 3.2) days, respectively] (P 0.05). In comparison with the contralateral limbs, the muscle had disuse atrophy and decreased strength in residual limbs of 2 groups. There was significant difference in the muscle strength between normal and affected limbs (P 0.05). Compared with direct anti-taken skin graft on amputation wound, the wound could be closed primarily by using the VSD combined with anti-taken skin graft. At the same time it could achieve

Falls are common among adults with leg amputations and associated with balance confidence. But subjective confidence is not equivalent with physical ability. This multivariate analyses of community-dwelling adults with leg amputations examined relationships among individual characteristics, falls, balance ability and balance confidence. Cross-sectional study. Community-dwelling adults with leg amputations recruited from a support group and prosthetic clinic. Subjects provided self-reported medical/fall history, prosthetic functional use, and Activities-specific Balance Confidence (ABC) questionnaire data. Balance ability was assessed with the Berg Balance Scale (BBS). Fall incidence was categorized as any fall (one or more) and recurrent falls (more than one). Multivariate logistic regression analyzed relationships within the two fall categories. Cross tabulations and ANOVA analyzed differences among subcategories. Fifty-four subjects (mean age 56.8) with various etiologies, amputation levels, and balance abilities participated. 53.7% had any fall; 25.9% had recurrent falls. Models for both fall categories correctly classified fall history in > 70% of subjects with combinations of the variables ABC, BBS, body-mass-index, and amputation level. Falls occurred regardless of clinical characteristics. Total BBS and select item scores were independent determinants of fall history. Unlike other balance-impaired populations, adults with leg amputation and better balance ability had greater odds of falling.

1996-07-01

To quantify the contribution of various risk factors to the risk of amputation in diabetic patients and to develop a foot risk scoring system based on clinical data. A population case-control study was undertaken. Eligible subjects were 1) 25-85 years of age, 2) diabetic, 3) 50% or more Pima or Tohono O'odham Indian, 4) lived in the Gila River Indian Community, and 5) had had at least one National Institutes of Health research examination. Case patients had had an incident lower extremity amputation between 1983 and 1992; control subjects had no amputation by 1992. Medical records were reviewed to determine risk conditions and health status before the pivotal event that led to the amputation. Sixty-one people with amputations were identified and compared with 183 control subjects. Men were more likely to suffer amputation than women (odds ratio [OR] 6.5, 95% CI 2.6-15), and people with diabetic eye, renal, or cardiovascular disease were more likely to undergo amputation than those without (OR 4.6, 95% CI 1.7-12). The risk of amputation was almost equally associated with these foot risk factors: peripheral neuropathy, peripheral vascular disease, bony deformities, and a history of foot ulcers. After controlling for demographic differences and diabetes severity, the ORs for amputation with one foot risk factor was 2.1 (95% CI 1.4-3.3), with two risk factors, 4.5 (95% CI 2.9-6.9), and with three or four risk factors, 9.7 (95% CI 6.3-14.8). Male Sex, end-organ complications of eye, heart, and kidney, and poor glucose control were associated with a higher amputation rate. Peripheral neuropathy, peripheral vascular disease, deformity, and a prior ulcer were similarly equally associated with an increased risk of lower extremity amputation.

Ectopic banking of amputated great toe for delayed thumb reconstruction: case report.

Valerio, Ian L; Hui-Chou, Helen G; Zelken, Jonathan; Basile, Patrick L; Ipsen, Derek; Higgins, James P

2014-07-01

Ectopic banking of amputated parts is a recognized technique for delayed replantation of an amputated part when the amputation stump will not permit immediate replantation. This is conventionally performed with the intent of transferring the injured part back to its anatomic position when the amputation stump is more appropriate for replantation. Current warfare conditions have led to a commonly encountered military trauma injury pattern of multiple extremity amputations with protected trunk and core structures. This pattern poses many challenges, including the limit or absence of donor sites for immediate or delayed flap reconstructive procedures. We describe a case in which we ectopically banked the great toe of an amputated lower extremity for delayed thumb reconstruction. Copyright © 2014 American Society for Surgery of the Hand.

2017-12-01

Active individuals with transfemoral amputations are provided a microprocessor-controlled knee with the belief that the prosthesis reduces their risk of falling. However, these prostheses are expensive and the cost-effectiveness is unknown with regard to falls in the transfemoral amputation population. The direct medical costs of falls in adults with transfemoral amputations need to be determined in order to assess the incremental costs and benefits of microprocessor-controlled prosthetic knees. We describe the direct medical costs of falls in adults with a transfemoral amputation. This is a retrospective, population-based, cohort study of adults who underwent transfemoral amputations between 2000 and 2014. A Bayesian structural time series approach was used to estimate cost differences between fallers and non-fallers. The mean 6-month direct medical costs of falls for six hospitalized adults with transfemoral amputations was US$25,652 (US$10,468, US$38,872). The mean costs for the 10 adults admitted to the emergency department was US$18,091 (US$-7,820, US$57,368). Falls are expensive in adults with transfemoral amputations. The 6-month costs of falls resulting in hospitalization are similar to those reported in the elderly population who are also at an increased risk of falling. Clinical relevance Estimates of fall costs in adults with transfemoral amputations can provide policy makers with additional insight when determining whether or not to cover a prescription for microprocessor-controlled prosthetic knees.

Amputations in natural disasters and mass casualties: staged approach.

Science.gov (United States)

Wolfson, Nikolaj

2012-10-01

Amputation is a commonly performed procedure during natural disasters and mass casualties related to industrial accidents and military conflicts where large civilian populations are subjected to severe musculoskeletal trauma. Crush injuries and crush syndrome, an often-overwhelming number of casualties, delayed presentations, regional cultural and other factors, all can mandate a surgical approach to amputation that is different than that typically used under non-disaster conditions. The following article will review the subject of amputation during natural disasters and mass casualties with emphasis on a staged approach to minimise post-surgical complications, especially infection.

Through Knee Amputation: Technique Modifications and Surgical Outcomes

Directory of Open Access Journals (Sweden)

Frank P Albino

2014-09-01

Full Text Available BackgroundKnee disarticulations (KD are most commonly employed following trauma or tumor resection but represent less than 2% of all lower extremity amputations performed in the United States annually. KDs provide enhanced proprioception, a long lever arm, preservation of adductor muscle insertion, decreased metabolic cost of ambulation, and an end weight-bearing stump. The role for KDs in the setting of arterial insufficiency or overwhelming infection is less clear. The purpose of this study is to describe technique modifications and report surgical outcomes following KDs at a high-volume Limb Salvage Center.MethodsA retrospective study of medical records for all patients who underwent a through-knee amputation performed by the senior author (C.E.A. between 2004 and 2012 was completed. Medical records were reviewed to collect demographic, operative, and postoperative information for each of the patients identified.ResultsBetween 2004 and 2012, 46 through-knee amputations for 41 patients were performed. The mean patient age was 68 and indications for surgery included infection (56%, arterial thrombosis (35%, and trauma (9%. Postoperative complications included superficial cellulitis (13%, soft tissue infection (4%, and flap ischemia (4% necessitating one case of surgical debridement (4% and four trans-femoral amputations (9%. 9 (22% patients went on to ambulate. Postoperative ambulation was greatest in the traumatic cohort and for patients less than 50 years of age, P<0.05. Alternatively, diabetes mellitus and infection reduced the likelihood of postoperative ambulation, P<0.01.ConclusionsKnee disarticulations are a safe and effective alternative to other lower extremity amputations when clinically feasible. For patient unlikely to ambulate, a through-knee amputation maximizes ease of transfers, promotes mobility by providing a counterbalance, and eliminates the potential for knee flexion contracture with subsequent skin breakdown.

Goal pursuit, goal adjustment, and affective well-being following lower limb amputation.

Coffey, Laura; Gallagher, Pamela; Desmond, Deirdre; Ryall, Nicola

2014-05-01

This study examined the relationships between tenacious goal pursuit (TGP), flexible goal adjustment (FGA), and affective well-being in a sample of individuals with lower limb amputations. Cross-sectional, quantitative. Ninety-eight patients recently admitted to a primary prosthetic rehabilitation programme completed measures of TGP, FGA, positive affect, and negative affect. Hierarchical regression analyses revealed that TGP and FGA accounted for a significant proportion of the variance in both positive and negative affect, controlling for sociodemographic and clinical characteristics. TGP was significantly positively associated with positive affect, while FGA was significantly negatively associated with negative affect. Moderated regression analyses indicated that the beneficial effect of FGA on negative affect was strongest at high levels of amputation-related pain intensity and low levels of TGP. TGP and FGA appear to influence subjective well-being in different ways, with TGP promoting the experience of positive affect and FGA buffering against negative affect. TGP and FGA may prove useful in identifying individuals at risk of poor affective outcomes following lower limb amputation and represent important targets for intervention in this patient group. What is already known on this subject? The loss of a limb has a significant impact on several important life domains. Although some individuals experience emotional distress following amputation, the majority adjust well to their limb loss, with some achieving positive change or growth as a result of their experiences. Theories of self-regulation propose that disruptions in goal attainment have negative affective consequences. The physical, social, and psychological upheaval caused by limb loss is likely to threaten the attainment of valued goals, which may leave individuals vulnerable to negative psychosocial outcomes if they do not regulate their goals in response to these challenges. According to the dual

Accumulating evidence suggests that smoking is associated with diabetic foot amputation. However, the currently available results are inconsistent and controversial. Therefore, the present study performed a meta-analysis to systematically review the association between smoking and diabetic foot amputation and to investigate the risk factors of diabetic foot amputation. Public databases, including PubMed and Embase, were searched prior to 29th February 2016. The heterogeneity was assessed using the Cochran's Q statistic and the I 2 statistic, and odds ratio (OR) and 95% confidence interval (CI) were calculated and pooled appropriately. Sensitivity analysis was performed to evaluate the stability of the results. In addition, Egger's test was applied to assess any potential publication bias. Based on the research, a total of eight studies, including five cohort studies and three case control studies were included. The data indicated that smoking significantly increased the risk of diabetic foot amputation (OR=1.65; 95% CI, 1.09-2.50; Pdiabetic foot amputation. Smoking cessation appears to reduce the risk of diabetic foot amputation.

The right adnexa were involved in 56% of the cases. The most common presenting complaint verbalized by the older girls was pain; however, 8 cases were identified in asymptomatic girls undergoing unrelated diagnostic testing. The auto-amputated adnexa is a rare finding in the pediatric population, but it must be considered as a possible explanation for the incidental finding of absence of the fallopian tube or ovary in the subgroup of patients who undergo surgery for any reason. Patients with an antecedent history of pelvic pain either chronic or intermittent in nature may be diagnosed with torsion or less frequently auto-amputation of the adnexa. A fetal "pelvic mass" or "ovarian cyst" may predispose the adnexa to torsion and subsequent auto-amputation either in-utero or post-delivery. Many of these antenatally diagnosed cysts and even subsequent auto-amputations are completely asymptomatic, however, and do not compromise fertility assuming the contralateral adnexa are normal. Thus expectant management is appropriate for small (less than 4 cm), asymptomatic simple cysts and even suspected auto-amputated adnexa in an asymptomatic patient.

The crude major lower limb amputation procedure rate is 8.8 per 100,000 of the population per year in Taiwan. From January 2002 to October 2006, patients that received major lower limb amputation in our department were enrolled in this study. Retrospective chart reviews concerning different factors that can affect the eventual postoperative functional status were investigated. Factors that affected the length of hospital stay included duration before amputation (P usage time were initial infection status (P = 0.021), renal function (P = 0.01), patient educational level (P = 0.016), and pretraining waiting time (P = 0.003). The duration of prosthetic training was affected by patient educational level (P = 0.004) and marital status (P = 0.024). In addition, subjective satisfaction about the usage of prosthesis was affected by pretraining waiting time (P = 0.001) and daily prosthesis usage time (P usage time was closely related to life quality improvement (P usage (P usage time of the prosthesis. Surgeons can make some contribution to accelerate amputation wound healing and stump maturation by choosing the correct operating procedure, delicately managing the soft tissue, and ascertaining proper wound care to improve the outcome.

2009-06-01

the long-term outcomes of wartime transtibial amputations have not been well documented. The purpose of this case series is to present the long-term functional, social, and psychological outcomes of modern-day military unilateral transtibial amputees. the Iranian Veterans Administration of the Khorasan province invited their Iranian military amputees from the Iran-Iraq War (1980-1988) to its medical center for evaluation. The patients filled out a detailed questionnaire and were interviewed and examined by each team member. two hundred (77%) of the 260 invited amputees were willing and able to come back for follow-up. Ninety-six of these patients (48%) were unilateral transtibial amputation. The average follow-up was 17.4 years (range 15-22 years). Land mines were the leading cause of war injury necessitating a transtibial amputation (68%). The most common symptoms about their amputated limbs were phantom sensations (54%), phantom pain (17%), and stump pain (42%). Lower back pain, contralateral (nonamputated limb) knee pain, and ipsilateral (amputated limb) knee pain were reported by 44%, 38%, and 13% of subjects, respectively. Sixty-five percent of patients were employed or had been employed for multiple years after their war injury. All patients were married, and 97% had children. Fifty-four percent of amputees reported psychological problems; 26% were currently utilizing psychological support services. at long-term follow-up, most military transtibial amputees experienced phantom sensation or some type of stump pain. More than half had persistent psychiatric problems, but only about half of these patients were receiving psychological treatment. Although this case series reports the status of these amputees, the next step would be to prospectively follow modern wartime amputees using standardized, validated outcome measures. With the goal of optimizing long-term amputee outcomes, researchers should correlate outcomes with demographics, injury characteristics, and

Full Text Available Abstract Background Surgical treatment of peripheral vascular disease (PVD in dialysis patients is controversial. Methods We examined the post-operative morbidity and mortality of surgical revascularization or amputation for PVD in a retrospective analysis of United States Renal Data System. Propensity scores for undergoing amputation were derived from a multivariable logistic regression model of amputation. Results Of the Medicare patients initiated on dialysis from Jan 1, 1995 to Dec 31, 1999, patients underwent surgical revascularization (n = 1,896 or amputation (n = 2,046 in the first 6 months following initiation of dialysis were studied. In the logistic regression model, compared to claudication, presence of gangrene had a strong association with amputation [odds ratio (OR 19.0, 95% CI (confidence interval 13.86–25.95]. The odds of dying within 30 days and within1 year were higher (30 day OR: 1.85, 95% CI: 1.45–2.36; 1 yr OR: 1.46, 95% CI: 1.25–1.71 in the amputation group in logistic regression model adjusted for propensity scores and other baseline factors. Amputation was associated with increased odds of death in patients with low likelihood of amputation (rd percentile of propensity score and moderate likelihood of amputation (33rd to 66th percentile but not in high likelihood group (>66th percentile. The number of hospital days in the amputation and revascularization groups was not different. Conclusion Amputation might be associated with higher mortality in dialysis patients. Where feasible, revascularization might be preferable over amputation in dialysis patients.

To examine the effect of swimming speed (v) on the biomechanical and physiological responses of a trained front-crawl swimmer with a unilateral arm amputation. A 13-y-old girl with a unilateral arm amputation (level of the elbow) was tested for stroke length (SL, horizontal displacement cover with each stroke cycle), stroke frequency (SF, inverse of the time to complete each stroke cycle), adapted index of coordination (IdCadapt, lag time between propulsive phases), intracycle velocity variation (IVV, coefficient of variation of the instantaneous velocity-time data), active drag (D, hydrodynamic resistance), and energy cost (C, ratio of metabolic power to speed) during trials of increasing v. Swimmer data showed a positive relationship between v and SF (R² = 1, P swimmers, mainly on interarm coordination, maintaining the lag time between propulsive phases, which influence the magnitude of the other parameters. These results might be useful to develop specific training and enhance swimming performance in swimmers with amputations.

2015-01-01

While ample research has examined the psychological experiences of men with limb amputations, minimal research has examined the psychological experiences of women with limb amputations. The present study utilizes a qualitative design to examine coping and posttraumatic growth in women with limb amputations. Thirty women completed the posttraumatic growth inventory (PTGI) and provided open-ended responses about coping, social support, discrimination, support groups, and acceptance. Interpretative phenomenological analysis was used to discern emergent and superordinate themes in qualitative responses. Superordinate themes included social support (friendships/family and community), self-beliefs, resources, physical complications, spirituality, specific strategies, and acceptance. Concerns related specifically to participants' gender identity included appearance and motherhood. Overall, women reported moderate-to-high PTGI scores. The current findings address a void in the literature by illuminating the unique perspective of women with amputations. Future research should use quantitative methodology to expand on our research findings, as well as assess interventions to assist women adjusting to limb loss.

In the acute postoperative period, fluid collections are common in lower extremity amputations. Whether these fluid collections increase the risk of infection is unknown. The purposes of this study were to determine (1) the percentage of patients who develop postoperative fluid collections in posttraumatic amputations and the natural course of the collection; (2) whether patients who develop these collections are at increased risk for infection; and to ask (3) are there objective clinical or radiologic signs that are associated with likelihood of infection when a fluid collection is present? We performed a review of all 300 patients injured in combat operations who sustained at least one major lower extremity amputation (at or proximal to the tibiotalar joint) and were treated definitively at our institution between March 2005 and April 2009. We segregated the groups based on whether cross-sectional imaging was performed less than 3 months (early group) after closure, greater than 3 months (late group) after closure, or not at all (control group, baseline frequency of infection). Our primary study cohort where those patients with a fluid collection in the first three months. The clinical course was reviewed and the primary outcome was a return to the operating room for irrigation and débridement with positive cultures. For those patients with cross-sectional imaging, we also collected objective clinical parameters within 24 hours of the scan (white blood cell count, maximum temperature, presence of bacteremia, tachycardia, oxygen desaturation), extremity examination (presence of erythema, warmth, and/or drainage), and characteristics of the fluid collections seen (size of the fluid collection, enhancement, complexity (simple versus loculated), surrounding edema, skin changes, tract formation, presence of air, and changes within the bone itself). The presence of a fluid collection on imaging was analyzed to determine whether it was associated with infection. We

Studies were conducted in order to determine the role of skin in restoring regenerative ability of x-rayed newt limbs. Non-x-rayed skin from the hindlimb was grafted in four ways to x-rayed (2680R) forelimbs, stripped of their own skin: proximal hindlimb skin to the proximal forelimb, proximal hindlimb skin to the distal forelimb, distal hindlimb skin to the distal forelimb, and distal hindlimb skin to the proximal forelimb. The forelimbs were immediately amputated at the distal extent of the skin graft. Thirty-two of thirty-five (92%) x-rayed forelimbs that had received hindlimb skin regenerated. Of those that regenerated, 28.1% were hindlimbs as shown by the presence of five digits; 34.4% had four digits or less; 31.2% had an outgrowth, but no morphogenesis of digits and 6.3% had two hands. The level of the regenerate from x-rayed limbs was determined by the stump, not the hindlimb skin graft. Only proximal hindlimb skin grafts were able to promote the formation of single 5 digit regenerates. X-rayed forelimb skin was grafted onto x-rayed (2680R) hindlimbs after the hindlimb muscle and skin was removed. X-rayed hindlimbs that had received grafts of forelimb skin produced 5-digit regenerates in 6 of 11 cases (55%). Only 2 (18%) had four digits. The remaining animals (27%) exhibited bud-like regenerates. It is concluded that skin is capable of restoring regenerative ability of x-rayed limbs and that these limbs are able to participate in the production of the regenerate

2016-01-01

To assess fall-related injury risk and risk factors in people with lower limb amputation. Prospective longitudinal cohort with follow-up every 6 months for up to 41 months. Community-dwelling adults with lower limb amputations of any etiology and level recruited from support groups and prosthetic clinics. Demographic and clinical characteristics were obtained by self-reported questionnaire and telephone or in-person follow-up. Fall-related injury incidence requiring medical care per person-month and adjusted hazard ratio of fall-related injury were calculated using multivariable proportional hazards regression modeling. A total of 41 subjects, with 782 follow-up person-months in total, had 11 fall-related injury incidents (14.1/1,000 person-months). During follow-up, 56.1% of subjects reported falling and 26.8% reported fall-related injury. Multivariable proportional hazard modeling showed that women were nearly 6 times more likely as men to experience fall-related injury and people of non-white race were 13 times more likely than people of white race to experience fall-related injury. The final predictive model also included vascular amputation and age. Risk of fall-related injury requiring medical care in people with lower limb amputation appears to be higher than in older adult inpatients. Intervention programs to prevent fall-related injury in people with lower limb amputation should target women and racial minorities.

Amputation history and rehabilitation of black men living in the greater Durban area who have had traumatic amputations of the lower limb

1995-03-01

Full Text Available A survey was undertaken amongst twenty five black men living in the greater Durban area who had had amputations of the lower limbs. The type of amputation care and the rehabilitation programme they underwent post-operatively is described. The sample included men from 24 to 50 years of age, of whom the majority were from rural areas. The amputation care intra and post-operatively was marked by the lack of emotional preparation pre-operatively, and lack of rehabilitation information and teaching afterwards. Most respondents had to find information for themselves. This lack of information and teaching seemed to impede physical rehabilitation, with stump sores and limited use of prostheses being the main problems. Vocational rehabilitation was almost totally absent. In contrast to the twenty two respondents who worked before their amputations, only four worked afterwards. The majority had to support their families alone; sixteen of them were totally reliant on a Disability Grant. These problems lead to social isolation, depression, loneliness and other psycho-social problems.

Full Text Available Abstract Background Major limb amputation is reported to be a major but preventable public health problem that is associated with profound economic, social and psychological effects on the patient and family especially in developing countries where the prosthetic services are poor. The purpose of this study was to outline the patterns, indications and short term complications of major limb amputations and to compare our experience with that of other published data. Methods This was a descriptive cross-sectional study that was conducted at Bugando Medical Centre between March 2008 and February 2010. All patients who underwent major limb amputation were, after informed consent for the study, enrolled into the study. Data were collected using a pre-tested, coded questionnaire and analyzed using SPSS version 11.5 computer software. Results A total of 162 patients were entered into the study. Their ages ranged between 2–78 years (mean 28.30 ± 13.72 days. Males outnumbered females by a ratio of 2:1. The majority of patients (76.5% had primary or no formal education. One hundred and twelve (69.1% patients were unemployed. The most common indication for major limb amputation was diabetic foot complications in 41.9%, followed by trauma in 38.4% and vascular disease in 8.6% respectively. Lower limbs were involved in 86.4% of cases and upper limbs in 13.6% of cases giving a lower limb to upper limb ratio of 6.4:1 Below knee amputation was the most common procedure performed in 46.3%. There was no bilateral limb amputation. The most common additional procedures performed were wound debridement, secondary suture and skin grafting in 42.3%, 34.5% and 23.2% respectively. Two-stage operation was required in 45.4% of patients. Revision amputation rate was 29.6%. Post-operative complication rate was 33.3% and surgical site infection was the most common complication accounting for 21.0%. The mean length of hospital stay was 22.4 days and mortality

Amputation is the removal of a limb or part of a limb by a surgical procedure in order to save the life of a person. The underlying reasons behind the occurrence of this tragic incidence may be varied. However, irrespective of its cause limb loss is associated with wide range of life challenges. The study was done to investigate the psychological sequel of an individual after losing a limb and to know the level of strain and pressure they experience after this traumatic event. It also attempts to examine the moderating role of some demographic traits such as age, sex and cause of limb loss in psychosocial adjustment to amputation. Methods: The study includes 100 adult amputees of both genders and the data was collected from major government and private hospitals of Peshawar district. Demographic data sheet was constructed in order to know the demographics traits of amputees and a standardize Psychological Adjustment Scale developed by Sabir (1999) was used to find out the level of psychological adjustment after limb loss. Results: Nearly all the amputees' exhibit signs of psychological maladjustment at varying degrees. Males showed much greater signs of maladjustment than women and young adults were much psychologically shattered and disturbed as a result of limb loss. Amputation caused by planned medical reasons leads to less adjustment issues as compared to unplanned accidental amputation in which patient were not mentally prepare to accept this loss. Conclusion: Psychological aspect of amputation is an important aspect of limb loss which needs to be addressed properly in order to rehabilitate these patients and helps them to adjust successfully to their limb loss.

To determine the relative and absolute reliability of a dual-task functional mobility assessment. Cross-sectional study. Academic rehabilitation hospital. Individuals (N=60) with lower extremity amputation attending an outpatient amputee clinic (mean age, 58.21±12.59y; 18, 80% male) who were stratified into 3 groups: (1) transtibial amputation of vascular etiology (n=20); (2) transtibial amputation of nonvascular etiology (n=20); and (3) transfemoral or bilateral amputation of any etiology (n=20). Not applicable. Time to complete the L Test measured functional mobility under single- and dual-task conditions. The addition of a cognitive task (serial subtractions by 3's) created dual-task conditions. Single-task performance on the cognitive task was also reported. Intraclass correlation coefficients (ICCs) measured relative reliability; SEM and minimal detectable change with a 95% confidence interval (MDC 95 ) measured absolute reliability. Bland-Altman plots measured agreement between assessments. Relative reliability results were excellent for all 3 groups. Values for the dual-task L Test for those with transtibial amputation of vascular etiology (n=20; mean age, 60.36±7.84y; 19, 90% men) were ICC=.98 (95% confidence interval [CI], .94-.99), SEM=1.36 seconds, and MDC 95 =3.76 seconds; for those with transtibial amputation of nonvascular etiology (n=20; mean age, 55.85±14.08y; 17, 85% men), values were ICC=.93 (95% CI, .80-.98), SEM=1.34 seconds, and MDC 95 =3.71 seconds; and for those with transfemoral or bilateral amputation (n=20; mean age, 58.21±14.88y; 13, 65% men), values were ICC=.998 (95% CI, .996-.999), SEM=1.03 seconds, and MDC 95 =2.85 seconds. Bland-Altman plots indicated that assessments did not vary systematically for each group. This dual-task assessment protocol achieved approved levels of relative reliability values for the 3 groups tested. This protocol may be used clinically or in research settings to assess the interaction between cognition

Objective: To assess the clinical effect and necessity of interventional treatment in diabetic foot before and after amputation. Methods: Combined intravascular angioplasty with intraarterial medicine perfusing were carried out in fourteen patients with diabetic foot including 10 patients treated before amputation and 4 after amputation involving superficial femoral, deep femoral, tibial and fitular arteries. Among them seventeen vessels with irregular stenosis and obstruction were treated by intravascular angioplasty through balloon dilation. Results: The technical successful rate was 100%, no complication happened. The symptoms were relieved in all patients after treatment, including promotion of lower extremity arterial blood perfusion, reducing range of amputation and wound healing after amputation. Conclusions: Intravascular interventional treatment is safe, effective and valuable in diabetic foot before and after amputation. (authors)

Full Text Available Brachial plexus injuries with intact yet flail limb presents with problems of persistent neuropathic pain and recurrent shoulder dislocations, that render the flail limb a damn nuisance. As treating surgeons, we are faced with the dilemma of offering treatment options, bearing in mind the patient’s functional status and expectations. We present a case of a 55-year old housewife with complete brachial plexus injury begging for surgical amputation of her flail limb, 6 years post-injury. Here we discuss the outcome of transhumeral amputation and the possibility of offering early rather than delayed amputations in this group of patients.

Caruana, Luana; Formosa, Cynthia; Cassar, Kevin

2015-08-01

To identify any significant differences in physiological test results between healing and non healing amputation sites. A single center prospective non-experimental study design was conducted on fifty subjects living with type 2 diabetes and requiring a forefoot or toe amputation. Subjects underwent non-invasive physiological testing preoperatively. These included assessment of pedal pulses, preoperative arterial spectral waveforms at the ankle, absolute toe pressures, toe-brachial pressure index and ankle-brachial pressure index. After 6 weeks, patients were examined to assess whether the amputation site was completely healed, was healing, had developed complications, or did not heal. There was no significant difference in ABPI between the healed/healing and the non-healing groups. Mean TBI (p=0.031) and toe pressure readings (p=0.014) were significantly higher in the healed/healing group compared to the non healing group. A significant difference was also found in ankle spectral waveforms between the two groups (p=0.028). TBIs, toe pressures and spectral waveforms at the ankle are better predictors of likelihood of healing and non-healing after minor amputation than ABPIs. ABPI alone is a poor indicator of the likelihood of healing of minor amputations and should not be relied on to determine need for revascularization procedures before minor amputation.

Limb amputations in fixed dystonia: a form of body integrity identity disorder?

Science.gov (United States)

Edwards, Mark J; Alonso-Canovas, Araceli; Schrag, Arnette; Bloem, Bastiaan R; Thompson, Philip D; Bhatia, Kailash

2011-07-01

Fixed dystonia is a disabling disorder mainly affecting young women who develop fixed abnormal limb postures and pain after apparently minor peripheral injury. There is continued debate regarding its pathophysiology and management. We report 5 cases of fixed dystonia in patients who sought amputation of the affected limb. We place these cases in the context of previous reports of patients with healthy limbs and patients with chronic regional pain syndrome who have sought amputation. Our cases, combined with recent data regarding disorders of mental rotation in patients with fixed dystonia, as well as previous data regarding body integrity identity disorder and amputations sought by patients with chronic regional pain syndrome, raise the possibility that patients with fixed dystonia might have a deficit in body schema that predisposes them to developing fixed dystonia and drives some to seek amputation. The outcome of amputation in fixed dystonia is invariably unfavorable. Copyright © 2011 Movement Disorder Society.

To report our technique and results with treating fingertip amputations with flaps and simultaneous nailbed grafts. We reconstructed 20 fingertip amputations with loss of bone and nail with flaps combined with nailbed grafts. We reconstructed the volar side of the fingertip with a flap, and the dorsal side of the fingertip with a nailbed grafted to the raw inner surface of the flap. We employed volar V-Y advancement flaps for transverse or dorsal oblique fingertip injuries and generally used abdominal flaps for volar oblique fingertip injuries. We harvested nailbeds from the amputated finger or from the patient's first toe. The length of the amputated fingertips was restored with the flaps, and the lost nailbeds were restored to their natural appearance with the nailbed grafts. We classified the results according to the length of the reconstructed fingertip and the appearance of the nail. Excellent or good results were achieved in 16 cases. Three cases had fair results and 1 had a poor result. We observed favorable results for distal fingertip amputations (Allen type II or III). In particular, most cases that were reconstructed with volar V-Y advancement flaps combined with nailbed grafts demonstrated favorable results. This method is useful for the restoration of dorsal oblique or transverse type fingertip amputations and is a good alternative when replantation is not an option.

Ren, Gao-hong; Pei, Guo-xian; Gu, Li-qiang; Guo, Gang

2004-08-01

To describe the surgical techniques and our experiences in fingertip replantation after amputation. On the basis of examination of the anatomic features and the degree of fingertip vascular injury, 32 amputated fingertips in 26 cases were replanted, and flexible revascularization procedures of both artery and vein anastomoses, artery-only anastomosis, arterialized vein and arteriovenous anastomosis were adopted. All the replanted fingertips were trained with comprehensive rehabilitation program. Twenty-nine replanted fingertips survived but 3 failed, and the overall survival rate was 90.06%. During the follow-up lasting from 4 months to 5 years, the 29 replanted fingertips survived with excellent blood supply, good sensory functions, satisfactory shape and functions according to the criteria by Society of Hand Surgery of Chinese Medical Association. Fingertip replantation after amputation can achieve not only high survival rate but also satisfactory appearance and functions as long as appropriate operative procedures are adopted with comprehensive rehabilitation therapy.

Finger amputations are common in accidents at home, work, and play. Apart from trauma, congenital disease and deformity also leads to finger amputation. This results in loss of function, loss of sensation as well as loss of body image. Finger prosthesis offers psychological support and social acceptance in such cases. This clinical report describes a method to fabricate ring retained silicone finger prosthesis in a patient with partial finger loss.

Lower extremity movement compensations following transtibial amputation are well-documented and are likely influenced by trunk posture and movement. However, the biomechanical compensations of the trunk and lower extremities, especially during high-demand tasks such as step ascent and descent, remain unclear. Kinematic and kinetic data were collected during step ascent and descent tasks for three groups of individuals: diabetic/transtibial amputation, diabetic, and healthy. An ANCOVA was used to compare peak trunk, hip and knee joint angles and moments in the sagittal and frontal planes between groups. Paired t-tests were used to compare peak joint angles and moments between amputated and intact limbs of the diabetic/transtibial amputation group. During step ascent and descent, the transtibial amputation group exhibited greater trunk forward flexion and lateral flexion compared to the other two groups (Pbiomechanical compensations of the trunk and lower extremities in individuals with dysvascular transtibial amputation, by identifying low back, hip, and knee joint moment patterns unique to transtibial amputation during stepping tasks. In addition, the results suggest that some movement compensations may be confounded by the presence of diabetes and precede limb amputation. The increased and asymmetrical loading patterns identified may predispose individuals with transtibial amputation to the development of secondary pain conditions, such as low back pain or osteoarthritis.

Standing balance in people with trans-tibial amputation due to vascular causes: A literature review.

Science.gov (United States)

Seth, Mayank; Lamberg, Eric

2017-08-01

Balance is an important variable to consider during the rehabilitation process of individuals with trans-tibial amputation. Limited evidence exists on the balance abilities of people with trans-tibial amputation due to vascular causes. The purpose of this article is to review literature and determine if standing balance is diminished in people with trans-tibial amputation due to vascular causes. Literature review. Data were obtained from PubMed, Google Scholar, OandP.org , CINHAL, and Science Direct. Studies were selected only if they included standing balance assessment of people with unilateral trans-tibial amputation due to vascular causes. The review yielded seven articles that met the inclusion criteria. The general test methodology required participants to stand still on force platforms, with feet together, while center of pressure or postural sway was recorded. According to the findings of this review, individuals with trans-tibial amputees due to vascular causes have diminished balance abilities. Limited evidence suggests their balance might be further diminished as compared to individuals with trans-tibial amputation due to trauma. Although the evidence is limited, because of the underlying pathology and presence of comorbidities in individuals with trans-tibial amputation due to vascular causes, one cannot ignore these findings, as even a minor injury from a fall may develop into a non-healing ulcer and affect their health and well-being more severely than individuals with trans-tibial amputation due to trauma. Clinical relevance Individuals with trans-tibial amputation due to vascular causes have diminished balance abilities compared to healthy individuals and individuals with trans-tibial amputation due to trauma. This difference should be considered when designing and fabricating prostheses. Prosthetists and rehabilitation clinicians should consider designing amputation cause-specific rehabilitation interventions, focussing on balance and other

The treatment of soft-tissue sarcomas of the extremities - prospective randomized evaluations of (1) limb-sparing surgery plus radiation therapy compared with amputation and (2) the role of adjuvant chemotherapy

International Nuclear Information System (INIS)

Rosenberg, S.A.; Tepper, J.; Glatstein, E.

1982-01-01

Between May 1975 and April 1981, 43 adult patients with high-grade soft tissue sarcomas of the extremities were prospectively randomized to receive either amputation at or above the joint proximal to the tumor, including all involved muscle groups, or to receive a limb-sparing resection plus adjuvant radiation therapy. The limb-sparing resection group received wide local excision followed by 5000 rads to the entire anatomic area at risk for local spread and 6000 to 7000 rads to the tumor bed. Both randomization groups received postoperative chemotherapy with doxorubicin (maximum cumulative dose 550 mg/m 2 ), cyclophosphamide, and high-dose methotrexate. Twenty-seven patients randomized to receive limb-sparing resection and radiotherapy, and 16 received amputation (randomization was 2:1). There were four local recurrences in the limb-sparing group and none in the amputation group (p 1 = 0.06 generalized Wilcoxon test). However, there were no differences in disease-free survival rates (83% and 88% at five years; p 2 = 0.99) between the limb-sparing group and the amputation treatment groups. Multivariate analysis indicated that the only correlate of local recurrence was the final margin of resection. Patients with positive margins of resection had a higher likelihood of local recurrence compared with those with negative margins (p 1 1 = 0.00008) and overall survival (95% vs. 74%; p 1 = 0.04)

2012-07-01

Full Text Available Abstract Introduction Replantation of a limb to the contralateral stump after bilateral traumatic amputations is rare. To the best of our knowledge, there are only a few reports of crossover lower limb replantation in the literature. Case presentation We treated a 37-year-old Chinese woman with bilateral lower limb crush injuries sustained in a traffic accident. Her lower limb injuries were at different anatomic levels. We performed emergency bilateral amputations followed by crossover replantation. Five years later, the woman had recovered well, and had perfect movement and stability in her replanted leg. After reviewing the literature, we thought that presentation of our patient’s case might provide useful information for clinicians. Conclusions Crossover replantation should be considered when evaluating a patient with bilateral lower limb injuries, thus allowing the patient to touch the ground and stand using their own foot.

The rate of upper-limb amputations is increasing, and the rejection rate of prosthetic devices remains high. People with upper-limb amputation do not fully incorporate prosthetic devices into their activities of daily living. By understanding the reaching behaviors of prosthesis users, researchers can alter prosthetic devices and develop training protocols to improve the acceptance of prosthetic limbs. By observing the reaching characteristics of the nondisabled arms of people with amputation, we can begin to understand how the brain alters its motor commands after amputation. We asked subjects to perform rapid reaching movements to two targets with and without visual feedback. Subjects performed the tasks with both their prosthetic and nondisabled arms. We calculated endpoint error, trajectory error, and variability and compared them with those of nondisabled control subjects. We found no significant abnormalities in the prosthetic limb. However, we found an abnormal leftward trajectory error (in right arms) in the nondisabled arm of prosthetic users in the vision condition. In the no-vision condition, the nondisabled arm displayed abnormal leftward endpoint errors and abnormally higher endpoint variability. In the vision condition, peak velocity was lower and movement duration was longer in both arms of subjects with amputation. These abnormalities may reflect the cortical reorganization associated with limb loss.

Despite the fact that limb amputation is a commonly performed procedure in veterinary medicine, quantitative data regarding outcomes are lacking. The intention of this study was to evaluate the effect of limb amputation on weight distribution to the remaining three limbs at a stance in dogs. Ten dogs with a prior forelimb amputation and ten dogs with a prior hindlimb amputation; all of which had no history of orthopaedic or neural disease in the remaining three limbs were included in the study. Standing weight bearing was evaluated with a commercial stance analyzer in all dogs. Five valid trials were obtained and a mean percentage of weight bearing was calculated for each remaining limb. The dogs with a previous forelimb amputation, and also those with a previous hindlimb amputation, had the largest mean increase in weight bearing in the contralateral forelimb. In conclusion, proactive monitoring of orthopaedic disease in the contralateral forelimb may be advisable in dogs with a previous limb amputation. In addition, when determining candidacy for a limb amputation, disease of the contralateral forelimb should be thoroughly evaluated.

Motor cortex changes after amputation are modulated by phantom limb motor control rather than pain

DEFF Research Database (Denmark)

Raffin, Estelle E.; Pascal, Giraux,; Karen, Reilly,

Amputation of a limb induces reorganization within the contralateral primary motor cortex (M1-c) (1-3). In the case of hand amputation, M1-c areas evoking movements in the face and the remaining part of the upper-limb expand toward the hand area. Despite this expansion, the amputated hand still...... reorganization and the residual M1-c activity of the amputated hand is unknown. This fMRI study aimed to determine this relationship...

To investigate new classification and repair methods for the traverse amputated fingertip. From March 2000 to October 2006, 20 cases of 20 fingers with traverse amputated fingertip, including 13 males and 7 females aged 17-47 years, were treated. Twenty patients (9 crush injuries, 5 cutting injuries and 6 sawing injuries) were classified into 4 types, namely type I (the distal one third of nail bed), type II (the middle of nail bed), type III (the proximal one third of nail bed), and type IV (the root of nail bed). There were 3 patients (2 index fingers and 1 little finger) of type I, 8 patients (2 thumbs, 3 index fingers and 3 middle fingers) of type II, 5 patients (3 index fingers, 1 ring finger and 1 little finger) of type III, and 4 patients (2 thumbs, 1 middle finger and 1 little finger) of type IV. The soft tissue defect ranged from 1.2 cm x 1.2 cm to 1.5 cm x 1.2 cm. The time from injury to surgery was 3-10 hours. Fingers of type I and type II were treated with forward flow axial flap and modified nail bed lengthening. Fingers of type III and type IV were treated with forward flow axial flap and partial nail bed replantation as well as modified nail bed lengthening. The flaps ranged in size from 1.5 cm x 1.2 cm to 2.0 cm x 1.4 cm. Twenty patients incisions healed by first intention and the flaps, nails and skin grafting survived. All donor sites healed by first intention. All patients were followed up for 2-6 months (4 months on average). The appearances of fingertips were good. The texture of the flap was soft, and the fingers had no tenderness and motor disturbance. The two-point discrimination was 4.5-6.5 mm. The finger nails of type I and type II extended 3-4 mm after operation, while the finger nails of type III and type IV extended 8-10 mm after operation. All finger nails were smooth and flat without pain. Hook nail happened in 1 case 6 months after operation. Classification of the injured fingers according to the condition of the amputation base is

The aim of treating thumb fingertip amputations with no indication for replantation is to reestablish functional and esthetic properties. From March 2005 to October 2008, we treated 14 patients with thumb fingertip amputation using palmar V-Y flaps combined with bone and nail bed grafts. There were 10 men and 4 women, whose ages at surgery ranged from 19 to 63 years (mean 35.8 years). In all, 11 of the injuries occurred in the dominant hand. According to Allen's classification, two were type II, seven were type III, and five were type IV. All patients underwent emergency surgery, with a time delay after injury of 3-12 h (mean 6.4 h). In each case, the amputation was a crush or avulsion injury, making microsurgical replantation not feasible. All of the flaps survived. At 8-17 months (average 12.8 months) of follow-up, the average subjective satisfaction score was 8.64. All patients experienced cold intolerance, and none of the patients complained of dysesthesia. Favorable results (excellent or good) were found in 78.6%. Thin primary nails appeared on the grafted nail bed about 3 weeks after surgery, following which the newly formed nail thickened and developed a more natural appearance. In one case, the new nail plate showed abnormal thickening due to hyperkeratosis. The bone graft healed at 5 weeks. The mean two-point discrimination was 7.5 mm. Grip strength was 10% less than that in the unaffected hand. Metacarpophalangeal and proximal interphalangeal joint mobility losses were less than 10°. All patients returned to their jobs. No patients had postoperative complications. We believe that the combination of palmar V-Y flap and bone and nail bed grafts provides a distinct advantage over other choices. It improves function when replantation is not an option.

To evaluate the methods for the replantation of the amputated penis in Chinese men. We performed a meta-analysis on the domestic literature relating replantation of the amputated penis, particularly its successful methods published from 1964 to January 2012. We identified 109 reports on 111 cases of replantation of the amputated penis that met the inclusion criteria, including 103 adults and 8 children. The mean age, warm ischemia time and total ischemia time were 29 +/- 11 years (range 2 - 56 years), 5.2 +/- 5.7 hours (range 0 - 38 hours) and 6.3 +/- 5.7 hours (range 1 - 38 hours). Fifty-three of the cases were treated by microsurgery and 44 by non-microsurgery. Complications occurred in 81 (73%) of the cases, including ED in 14 cases, urethral stricture in 16, urinary fistula in 8, skin necrosis in 58 and skin sensory abnormality in 31. The incidences of ED, urethral stricture and urinary fistula exhibited significant differences between the microsurgery and non-microsurgery groups of the partial amputation patients (P penis and reduction of complications, and therefore can be regarded as a "standard" method for penile replantation in China.

The Plasticity of Brain Gray Matter and White Matter following Lower Limb Amputation

Directory of Open Access Journals (Sweden)

Guangyao Jiang

2015-01-01

Full Text Available Accumulating evidence has indicated that amputation induces functional reorganization in the sensory and motor cortices. However, the extent of structural changes after lower limb amputation in patients without phantom pain remains uncertain. We studied 17 adult patients with right lower limb amputation and 18 healthy control subjects using T1-weighted magnetic resonance imaging and diffusion tensor imaging. Cortical thickness and fractional anisotropy (FA of white matter (WM were investigated. In amputees, a thinning trend was seen in the left premotor cortex (PMC. Smaller clusters were also noted in the visual-to-motor regions. In addition, the amputees also exhibited a decreased FA in the right superior corona radiata and WM regions underlying the right temporal lobe and left PMC. Fiber tractography from these WM regions showed microstructural changes in the commissural fibers connecting the bilateral premotor cortices, compatible with the hypothesis that amputation can lead to a change in interhemispheric interactions. Finally, the lower limb amputees also displayed significant FA reduction in the right inferior frontooccipital fasciculus, which is negatively correlated with the time since amputation. In conclusion, our findings indicate that the amputation of lower limb could induce changes in the cortical representation of the missing limb and the underlying WM connections.

Despite the severity of consequences associated with traumatic amputation, little is known about the epidemiology or healthcare resource burden of amputation injuries, and even less is known about these injuries in the pediatric population. An analysis of patients aged lawn mower, motorized vehicle or explosives/fireworks, and children's hospital type were associated with longer LOS. Pediatric traumatic amputations contribute substantially to the health resource burden in the United States, resulting in 21 million dollars in inpatient charges annually. More effective interventions to prevent these costly injuries among children must be implemented.

To discuss the replantation of fingertip amputation in lack of availability of intravenous anastomosis. From November 2009 to November 2010, 86 patients (104 fingers) with fingertip amputation were treated with replantatioin, including 64 males and 22 females, with an average age of 26 years ranging from 2 to 64 years. The time from injury to therapy was from 30 min to 12 h, time of broken finger ischemia was from 2.5 to 12 h. Preoperative examination showed no obvious abnormalities. Four different replantation methods were selectively applied to these 104 amputated fingertips of 86 cases: (1) replantation with anastomosis of single or bilateral proper digital artery in 37 fingers; (2) replantation with arteriovenous bypass in 27 fingers; (3) replantation with exclusive anastomosis of digital artery in 24 fingers; (4) replantation with removing the palmar pocket method in 16 fingers. One hundred and two of 104 amputated fingertips were survived. Among these survived fingers,75 cases (92 fingers) were followed-up for 6 to 24 months. According to the assessment standard of Chinese Medical Association of Hand Surgery, the results were excellent in 52 cases, good in 19, poor in 4. It benefits to expand the indications and improve the survival rate of replantation of fingertip amputation with the correct choice of different replantation methods according to the injury situation of the broken fingertip artery after debridement under the microscope.

2017-08-01

Distal finger amputations pose a therapeutic problem with the distal fragment quality. Reimplantation remains the reference treatment for functional and aesthetic recovery of the hand. The interest of this study is to propose the reposition flap as an alternative to different hedging techniques in the proximal stump, in many situations where revascularization is impossible. It consists in osteosynthesis of the bone fragment and its coverage by a pedicled local flap. The technique of reposition flap was evaluated retrospectively between 2003 and 2016 through a study of 13 patients compiled in Nabeul orthopedic department. For each patient, the sensitivity, the pulp trophicity, the interphalangeal mobility, the digital length, the appearance of the nail and radiological consolidation were evaluated. The reposition flap keeps more than 80% of the length of p3. This procedure improves nail aesthetics in comparison with the regularizations. There is no significant difference in sensitivity of the pulp or of the mobility of the distal inter-phalangeal (DIP) joint as a function of the technique studied. However there is a significant difference in average test of the Quick Dash (350 against 500 for regularizations). The reposition flap seems to be a good alternative to regularization in the context of trans-p3 fingers amputations, in which the distal fragment is not revascularizable. It allows better aesthetic and functional results. Copyright © 2017 Daping Hospital and the Research Institute of Surgery of the Third Military Medical University.

Complications from diabetes mellitus including major lower extremity amputation may have significant impact on a patient's mortality. This study determined what impact the addition of a limb salvage and diabetic foot program involving podiatry had at an academic institution over 16years by analyzing high-low amputation ratio data. The high-low amputation ratio in the diabetic population who underwent non-traumatic amputation of the lower extremity was retrospectively evaluated at an academic institution via cohort discovery of the electronic medical record and analysis of billing over 16years. We directly compared two eras, one without podiatry and one with a podiatry presence. It was found that with the addition of a podiatry program, limb salvage rates significantly increased (R 2 (without podiatry)=0.45, R 2 (with podiatry)=0.26), with a significant change in both the rate of limb salvage per year (-0.11% per year versus -0.36% per year; ppodiatry to 0.60 with podiatry). Of note, approximately 40 major lower extremity amputations were avoided per year with the addition of a podiatry program (ppodiatry program present at an academic institution, major lower extremity amputations can be avoided and more limbs can be salvaged, thus preventing some of the moribund complications from this condition.

Symptomatic HO was diagnosed in 36 (22.8%) patients, and 94% patients had mild HO on radiographic scoring. Rate of HO in amputations related to trauma was not increased compared with those of other etiologies. Surgical resection of the ectopic bone was required in 4 (11%) patients. HO is seen commonly after civilian lower limb amputation regardless of etiology. The prevalence was less than that observed in previous reports from military populations. This is the first report estimating the prevalence of HO in adult civilian amputees. Copyright © 2014 American Congress of Rehabilitation Medicine. Published by Elsevier Inc. All rights reserved.

[The endo-exo prosthesis for patients with a problematic amputation stump].

Frölke, Jan Paul M; van de Meent, Henk

2010-01-01

Following lower limb amputation, quality of life is highly related to the ability to use a prosthetic limb. The conventional way to attach a prosthetic limb to the body is with a socket. Many patients experience serious discomfort wearing a conventional prosthesis because of pain, instability during walking, pressure sores, bad smell or skin irritation. In addition, sitting is uncomfortable and pelvic and lower back pain due to unstable gait is often seen in these patients. The main disadvantage of the current prosthesis is the attachment of a rigid prosthesis socket to a soft and variable body. The socket must fit tightly for stability during walking but should also be comfortable for sitting. The implantation of an osseointegrated, intramedullary, transcutaneously conducted prosthesis is a new procedure for attaching a limb prosthesis to the human body without the disadvantages of the conventional prosthesis. The intramedullary prosthesis is designed with a rough surface resembling cancellous bone to enable a secure solid integration with the long bone. We treated two patients with this new prosthesis, a 44-year-old man after a transfemoral amputation, and a 32-year-old woman after a lower leg amputation; both amputations were necessary because of trauma. Those two patients are now, more than one year after the operation, showing excellent functional results without infectious complications. We assume that endo-exo prosthesis may be a promising option for selected patients unable to use a conventional prosthesis because of a problematic amputation stump.

More than 25% of those who followed the recommended treatment and rehabilitation programme to prepare the amputation stump, reduced contracture and enhanced physical working abilities were declared to be appropriate for further prostheses. This indicates serious shortcomings in medical treatments during the early post-amputation period.

Full Text Available Amputation of the penis is a rare condition reported from various parts of the world as isolated cases or small series of patients; the common etiology is self-mutilating sharp amputation or an avulsion or crush injury in an industrial accident. A complete reconstruction of all penile structures should be attempted in one stage which provides the best chance for full rehabilitation of the patient. We report here a single case of total amputation of the penis in an acute paranoid schizophrenic patient .The penis was successfully reattached using a microsurgical technique. After surgery, near-normal appearance and function including a good urine flow and absence of urethral stricture, capabilities of erection and near normal sensitivity were observed.

In 59 above-knee amputations healing of the stumps was correlated with the local skin perfusion pressure (SPP) measured preoperatively as the external pressure required to stop isotope washout using 1318-- or 125I--antipyrine mixed with histamine. Out of the 11 cases with an SPP below 30 mm...... on the stumps was on average only slightly and insignificantly higher than the preoperative values, explaining why the preoperative values related so closely to the postoperative clinical course.

Objective To determine trends in the incidence of foot-related hospitalisation and amputation amongst persons with diabetes in Queensland (Australia) between 2005 and 2010 that coincided with changes in state-wide ambulatory diabetic foot-related complication management. Methods All data from cases admitted for the principal reason of diabetes foot-related hospitalisation or amputation in Queensland from 2005–2010 were obtained from the Queensland Hospital Admitted Patient Data Collection dataset. Incidence rates for foot-related hospitalisation (admissions, bed days used) and amputation (total, minor, major) cases amongst persons with diabetes were calculated per 1,000 person-years with diabetes (diabetes population) and per 100,000 person-years (general population). Age-sex standardised incidence and age-sex adjusted Poisson regression models were also calculated for the general population. Results There were 4,443 amputations, 24,917 hospital admissions and 260,085 bed days used for diabetes foot-related complications in Queensland. Incidence per 1,000 person-years with diabetes decreased from 2005 to 2010: 43.0% for hospital admissions (36.6 to 20.9), 40.1% bed days (391 to 234), 40.0% total amputations (6.47 to 3.88), 45.0% major amputations (2.18 to 1.20), 37.5% minor amputations (4.29 to 2.68) (p Queensland over a recent six-year period.

Little is known about whether and how multimodal representations of the body (BRs) and of the space around the body (Peripersonal Space, PPS) adapt to amputation and prosthesis implantation. In order to investigate this issue, we tested BR in a group of upper limb amputees by means of a tactile distance perception task and PPS by means of an audio-tactile interaction task. Subjects performed the tasks with stimulation either on the healthy limb or the stump of the amputated limb, while wearing or not wearing their prosthesis. When patients performed the tasks on the amputated limb, without the prosthesis, the perception of arm length shrank, with a concurrent shift of PPS boundaries towards the stump. Conversely, wearing the prosthesis increased the perceived length of the stump and extended the PPS boundaries so as to include the prosthetic hand, such that the prosthesis partially replaced the missing limb.

Full Text Available Abstract Background The forelimb amputee poses many reconstructive challenges in the clinical setting, and there is a paucity of established surgical models for study. To further elucidate the pathogenic process in amputation neuroma formation, we created a reproducible, well-tolerated rabbit forelimb amputation model. Methods Upon approval from the Institutional Animal Care and Use Committee, 5 New Zealand White rabbits underwent left forelimb amputation. During this initial surgery, the median, radial and ulnar nerves were transected 1.6-2.5 (mean 2.0 cm distal to the brachial plexus, transposed onto the anterior chest wall and preserved at length. Six weeks subsequent to the amputation, the distal 5 mm of each neuroma was excised, and the remaining stump underwent histomorphometric analysis. Results The nerve cross sectional areas increased by factors of 1.99, 3.17, and 2.59 in the median (p = 0.077, radial (p Conclusion Given that the surgical model appears well-tolerated by the rabbits and that patterns of morphologic change are consistent and reproducible, we are encouraged to further investigate the utility of this model in the pathogenesis of neuroma formation.

To evaluate the feasibility of the Nintendo WiiFit™ as an adjunct to usual therapy in individuals with a lower limb amputation. The study was a Multiple Baseline (AB) Single Subject Research Design. Subjects were ≥19 years old, had their first unilateral transtibial or transfemoral amputation  ≤12 months ago, and were participating in prosthetic training. WiiFit training was provided for 30 min, 5 times a week, for a minimum of 2 and a maximum of 6 weeks in addition to usual therapy. Feasibility indicators were safety, post-intervention fatigue and pain levels, adherence, and subject's acceptability of the program as measured by the Short Feedback Questionnaire-modified (SFQ-M). The primary clinical outcome was walking capacity assessed by the 2 Minute Walk Test (2MWT). The secondary clinical outcomes were the Short Physical Performance Battery, L-test, and Activities-Specific Balance Confidence. Subjects (4 transtibial; 2 transfemoral) had a median age of 48.5 years (range = 45-59 years). No adverse events associated with the intervention occurred. Median pain and fatigue levels were 1.3 (range = 0.5-3.5) and 3.1 (range = 1.4-4.1), respectively. Median adherence was 80%. Subjects found the WiiFit enjoyable and acceptable (median SFQ-M = 35). Five subjects showed statistical improvement on the 2MWT and four on the secondary outcomes (p < 0.05). The WiiFit intervention was found to be feasible in individuals with unilateral lower limb amputation. This research provides the foundation for future clinical research investigating the use of the WiiFit as a viable adjunctive therapy to improve outcomes in individuals with unilateral lower limb amputation who are participating in prosthetic training.

Ectopic major transplantation for salvage of upper and lower extremity amputations

Directory of Open Access Journals (Sweden)

Nazerani Shahram

2013-12-01

Full Text Available 【Abstract】Objective: Ectopic tissue transplanta- tion is not a new idea. Godina and his colleagues pioneered this method in the 1980s. This method is a last resort method of preserving an amputated body part, which consists of banking the amputated segment in an ectopic area and re- turning it to its native place at a later date. In this article we present our experience with this demanding procedure. Methods: Debridement was the mainstay of this procedure. The stump and amputated part are carefully de- brided and the stump was either closed primarily or covered by a flap. The amputated part was transplanted to one of several banking sites in the body and at a later date it will be transferred to its native site in an elective setting. Results: Seven patients meeting the set criteria for ectopic transplantation were enrolled in this study. The over- all success rate was about 70%, lower than expected but these are cases of severe crush injury. Although the func- tional recovery of these patients are very low, all of the successful cases except one could find a job as a janitor or light manual worker. No patient could return to his previous job. Conclusion: Ectopic transplantation of body parts is an accepted method of treatment of severely crushed ex- tremity or finger injuries. In our country an amputee has very little chance of finding a job instead a disabled person can. In addition in Iran cultures amputation is seen as pu- nishment of either the God or the society, so it is not well accepted and many patients persist on saving the limb even with no functional recovery. None of our successful cases could return to his previous occupation but almost all of them could find a job as janitors or light manual workers.

Exploring ethical justification for self-demand amputation.

Science.gov (United States)

Tomasini, Floris

2006-01-01

Self-demand amputees are persons who need to have one or more healthy limbs or digits amputated to fit the way they see themselves. They want to rid themselves of a limb that they believe does not belong to their body-identity. The obsessive desire to have appendages surgically removed to fit an alternative body-image is medically and ethically controversial. My purpose in this paper is to provide a number of normative and professional ethical perspectives on whether or not it is possible to justify surgery for self-demand amputees. In doing so I proceed dialogically, moving between empirical context and normative theory, revealing the taken for granted normative assumptions (what I call the natural attitude--a technical term borrowed from phenomenology) that provide ethical limits to justifying the treatment of self-demand amputees. While I critically examine both Kantian responses against as well as Utilitarian responses for amputation on demand, I conclude that neither normative tradition can fully incorporate an understanding of what it is like to be a self-demand amputee. Since neither theory can justify the apparent non-rational desire of amputation on demand, ethical justification, I argue, falls short of the recognition that there may be a problem. To end, I introduce a meta-ethical idea, "the struggle for recognition," opening up the theoretical possibility of a hermeneutics of recognition before ethical justification that may be more sensitive to the problem of radical embodied difference exemplified by self-demand amputees.

Amputation injuries in children occur in motor vehicle, farming and, importantly, lawn mower accidents. Treatment of lawn mower related injuries is complicated by gross wound contamination, avascular tissue, soft tissue defects and exposed bone. Many treatment options exist and often an adequate prosthetic supply is needed for rehabilitation. We report on an 8-year old boy who got under a ride-on lawn mower and sustained a subtotal amputation of his right foot. After initial surgery an amputation was subsequently necessary. For this, it had to be taken into account that the traumatic loss of the talus, calcaneus and parts of the cuboid bone would result in a length shortening of the right leg and so far not injured metatarsal and tarsal bones had to be sacrificed. Thus, we aimed to develop a new operation technique to optimize stump length as well as preserve tarsal bones and the possibility of limb growth. In order to achieve this, we performed a new stump forming operation in which we integrated uninjured tarsal and metatarsal bones. First a Lisfranc's amputation was performed and a metatarsal bone was kept aside. The talus, calcaneus as well as the cuboid bone were either completely or almost completely destroyed and were removed. The remaining cuneiform bones were transfixed by a notched metatarsal bone, thus achieving a tarsal arthrodesis, and the cartilages of the proximal joint surfaces were removed. The cartilage of the cranial and caudal navicular as well as the distal tibial joint surface was also removed and an arthrodesis between the distal tibia and the navicular bone was achieved by crossed Kirschner wires. Finally the cuneiform bones were placed inferior to the navicular bone. Further stump coverage was managed by skin and muscle flaps as well as split skin graft. Our patient was discharged on day 34. A fluent gait without crutches as well as sports activities were possible again as early as 6 1/2 months after the injury. Using our stump forming

Clinical and theoretical parallels between desire for limb amputation and gender identity disorder.

Science.gov (United States)

Lawrence, Anne A

2006-06-01

Desire for amputation of a healthy limb has usually been regarded as a paraphilia (apotemnophilia), but some researchers propose that it may be a disorder of identity, similar to Gender Identity Disorder (GID) or transsexualism. Similarities between the desire for limb amputation and nonhomosexual male-to-female (MtF) transsexualism include profound dissatisfaction with embodiment, related paraphilias from which the conditions plausibly derive (apotemnophilia and autogynephilia), sexual arousal from simulation of the sought-after status (pretending to be an amputee and transvestism), attraction to persons with the same body type one wants to acquire, and an elevated prevalence of other paraphilic interests. K. Freund and R. Blanchard (1993) proposed that nonhomosexual MtF transsexualism represents an erotic target location error, in which men whose preferred erotic targets are women also eroticize their own feminized bodies. Desire for limb amputation may also reflect an erotic target location error, occurring in combination with an unusual erotic target preference for amputees. This model predicts that persons who desire limb amputation would almost always be attracted to amputees and would display an increased prevalence of gender identity problems, both of which have been observed. Persons who desire limb amputation and nonhomosexual MtF transsexuals often assert that their motives for wanting to change their bodies reflect issues of identity rather than sexuality, but because erotic/romantic orientations contribute significantly to identity, such distinctions may not be meaningful. Experience with nonhomosexual MtF transsexualism suggests possible directions for research and treatment for persons who desire limb amputation.

Body integrity identity disorder (BIID)--is the amputation of healthy limbs ethically justified?

Science.gov (United States)

Müller, Sabine

2009-01-01

The term body integrity identity disorder (BIID) describes the extremely rare phenomenon of persons who desire the amputation of one or more healthy limbs or who desire a paralysis. Some of these persons mutilate themselves; others ask surgeons for an amputation or for the transection of their spinal cord. Psychologists and physicians explain this phenomenon in quite different ways; but a successful psychotherapeutic or pharmaceutical therapy is not known. Lobbies of persons suffering from BIID explain the desire for amputation in analogy to the desire of transsexuals for surgical sex reassignment. Medical ethicists discuss the controversy about elective amputations of healthy limbs: on the one hand the principle of autonomy is used to deduce the right for body modifications; on the other hand the autonomy of BIID patients is doubted. Neurological results suggest that BIID is a brain disorder producing a disruption of the body image, for which parallels for stroke patients are known. If BIID were a neuropsychological disturbance, which includes missing insight into the illness and a specific lack of autonomy, then amputations would be contraindicated and must be evaluated as bodily injuries of mentally disordered patients. Instead of only curing the symptom, a causal therapy should be developed to integrate the alien limb into the body image.

Shoe adaptation after amputation of the II - V phalangeal bones of the foot.

Science.gov (United States)

Rommers, G M; Diepstraten, H J M; Bakker, E; Lindeman, E

2006-12-01

In The Netherlands, about 50% of all amputations of the lower limb are toes and forefoot amputations. Traumata of toes and mid-foot are rare. Preservation of the foot is the primary goal for treatment. Crush injuries of the foot may be associated with prolonged morbidity. This case study presents an insole solution for the solitary first phalangeal bone after amputation of the phalangeal bones II - V. The normal adaptation for forefoot amputations is stiffening of the sole of the shoe and a rocker bar to improve the toe off phase with load reduction of the forefoot. Because the patient had to do excessive stair climbing during work another solution was chosen. As a foot orthosis, a metal soleplate was made in order to have free movement during loading and toe-off during walking. The soleplate gives safety and provides self-adjusting properties after toe off. This enables the shoe technician to make a shoe without a rocker bar or an extra stiff insole. The 0.5 mm custom-made spring-steel plate is also used as a protective in industrial safety shoes. To improve shoe adaptation more research and case reports have to be published in order to inform doctors and shoe technicians about everyday solutions to partial foot amputations.

Individuals who have undergone a lower limb amputation require comprehensive rehabilitation from the multidisciplinary team to ensure optimal treatment outcomes and social integration. Physiotherapists play a pivotal role within the multidisciplinary team and offer patients physical and psychosocial rehabilitative care. Determining patients' satisfaction levels and exploring factors affecting adherence to physiotherapy interventions can inform practice and improve service delivery of rehabilitation within resource poor settings such as South Africa. To determine the level of satisfaction with physiotherapy services rendered to acute and sub-acute in-patients with lower limb amputations and to explore factors affecting adherence to physiotherapy intervention. A prospective survey of 35 patients with lower limb amputations from four public hospitals in South Africa was undertaken. A modified version of the Hampstead rehabilitation centre patient satisfaction questionnaire was utilised. Majority of participants were satisfied with the physiotherapy services whilst a few reported dissatisfaction. Three themes emerged whilst exploring the patients' experience relating to adherence to physiotherapy programmes. Themes included service delivery, patient-therapist interaction and participation barriers and facilitators. Recommendations aimed to improve quality of care and healthcare outcomes thereby enhancing the participants' adherence to the physiotherapy programme.

Distal phalanx amputation with delayed presentation and successful reconstruction with reposition and flap after 2 weeks

Directory of Open Access Journals (Sweden)

Jefferson Braga-Silva

2016-01-01

Full Text Available Traumatic finger amputations are common, causing significant functional and cosmetic deficits. Microsurgical replantation techniques are the mainstay of treatment for most such injuries although they require adequate conservation of the amputated segment for a successful result. In distal finger amputations, replantation is the procedure of choice, as long as the amputated fragment is viable. If replantation is not an option, reposition + flap using a neurovascular flap can be an efficient option, as this offers improved skin coverage. To the best of our knowledge, this case illustrates the longest cold ischaemic time with a successful outcome.

BACKGROUND Postoperative readmission, recently identified as a marker of hospital quality in the Affordable Care Act, is associated with increased morbidity, mortality and healthcare costs, yet data on readmission following lower extremity amputation is limited. We evaluated risk factors for readmission and post-discharge adverse events following lower extremity amputation in the ACS-NSQIP. STUDY DESIGN All patients undergoing transmetatarsal (TMA), below-knee (BKA) or above-knee amputation (AKA) in the 2011 – 2012 NSQIP were identified. Independent pre-discharge predictors of 30-day readmission were determined using multivariable logistic regression. Readmission indication and re-interventions, available in the 2012 NSQIP only, were also evaluated. RESULTS We identified 5,732 patients undergoing amputation (TMA: 12%; BKA: 51%; AKA: 37%). Readmission rate was 18%. Post-discharge mortality rate was 5% (TMA: 2%; BKA: 3%; AKA: 8%; preadmission included chronic nursing home residence (OR: 1.3; 95% CI: 1.0–1.7), non-elective surgery (OR: 1.4; 95% CI: 1.1–1.7), prior revascularization/amputation (OR: 1.4; 95% CI: 1.1–1.7), preoperative congestive heart failure (OR: 1.7; 95% CI: 1.2–2.4), and preoperative dialysis (OR: 1.5; 95% CI: 1.2–1.9). Guillotine amputation (OR: .6; 95%CI: .4–.9) and non-home discharge (OR: .7; 95%CI: .6–1.0) were protective of readmission. Wound related complications accounted for 49% of readmissions. CONCLUSIONS Post discharge morbidity, mortality and readmission are common following lower extremity amputation. Closer follow up of high risk patients, optimization of medical comorbidities and aggressive management of wound infection may play a role in decreasing readmission and post discharge adverse events.

Tail tip amputation with minimal restraint is not widely used for mouse phlebotomy. In part, this infrequency may reflect policies influenced by tail tip amputation procedures for genotyping, which involve greater handling and tissue removal. To assess tail tip amputation with minimal restraint as a phlebotomy technique, we compared it with 2 more common methods: scruffing with facial vein puncture and lateral tail vein incision with minimal restraint. Blood glucose levels, audible and ultrasonic vocalizations, postphlebotomy activity and grooming behavior, open field and elevated plus maze behaviors, nest-building scores, and histologic changes at the phlebotomy site were evaluated. Mice in the facial vein phlebotomy group produced more audible vocalizations, exhibited lower postphlebotomy activity in the open field, and had more severe histologic changes than did mice in the tail incision and tail tip amputation groups. Facial vein phlebotomy did not affect grooming behavior relative to sham groups, whereas tail vein incision-but not tail tip amputation-increased tail grooming compared with that in control mice. Blood glucose levels, nest-building scores, and elevated plus maze behavior did not differ between groups, and no mice in any group produced ultrasonic vocalizations. Tail tip amputation mice did not perform differently than sham mice in any metric analyzed, indicating that this technique is a potentially superior method of blood collection in mice in terms of animal wellbeing.

To date, history of a contralateral amputation as a potential predictor of outcomes after lower extremity bypass (LEB) for critical limb ischemia (CLI) has not been studied. We sought to determine if a prior contralateral lower extremity amputation predicts worse outcomes in patients undergoing LEB in the remaining intact limb. A retrospective analysis of all patients undergoing infrainguinal LEB for CLI between 2003 and 2010 within hospitals comprising the Vascular Study Group of New England was performed. Patients were stratified according to whether or not they had previously undergone a contralateral major or minor amputation before LEB. Primary end points included major amputation and graft occlusion at 1 year postoperatively. Secondary end points included in-hospital major adverse events, discharge status, and mortality at 1 year. Of 2636 LEB procedures, 228 (8.6%) were performed in the setting of a prior contralateral amputation. Patients with a prior amputation compared to those without were younger (66.5 vs 68.7; P = .034), more like to have congestive heart failure (CHF; 25% vs 16%; P = .002), hypertension (94% vs 85%; P = .015), renal insufficiency (26% vs 14%; P = .0002), and hemodialysis-dependent renal failure (14% vs 6%; P = .0002). They were also more likely to be nursing home residents (8.0% vs 3.6%; P = .036), less likely to ambulate without assistance (41% vs 80%; P < .0002), and more likely to have had a prior ipsilateral bypass (20% vs 12%; P = .0005). These patients experience increased in-hospital major adverse events, including myocardial infarction (MI; 8.9% vs 4.2%; P = .002), CHF (6.1% vs 3.4%; P = .044), deterioration in renal function (9.0% vs 4.7%; P = .006), and respiratory complications (4.2% vs 2.3%; P = .034). They were less likely to be discharged home (52% vs 72%; P < .0001) and less likely to be ambulatory on discharge (25% vs 55%; P < .0001). Although patients with a prior contralateral amputation experienced increased rates of

Spinal cord injury (SCI) requires considerable psychological adjustment to physical limitations and complications. One particularly severe complication of SCI is foot skin breakdown, which can result in lower limb amputation. Relative to SCI adjustment, amputation may produce one of two psychological outcomes: (a.) the fragile self-concept of a person with SCI may be reduced further by limb amputation, or (b.) amputation of a diseased, nonfunctional limb may be associated with restored health and improved self-concept. To better understand the effects of amputation, 26 males with SCI, 11 of whom had a lower limb amputation, were administered the Tennessee Self-Concept Scale (TCS) and the Personal Body Attractiveness Scale (PBAS). The study revealed that persons with SCI with amputation had higher Physical and Total self-concept scores on the TSCS, showing a slightly more positive self-concept. On the PBAS, although there were no significant differences in the scores for the legs, ankles, or feet, the persons with SCI with amputation had higher score on the Satisfaction subscale, indicating a slightly greater satisfaction with their thigh in their body image. Implications for future study include replication with larger sample sizes, inclusion of women in the sample, and a longitudinal study. Several nursing interventions are identified.

Full Text Available Abdullah M Al-WahbiDepartment of Surgery, King Abdulaziz Medical City and King Saud bin Abdulaziz University for Health Sciences, Riyahd, Kingdom of Saudi ArabiaBackground: Diabetic foot complications are a leading cause of lower extremity amputation. With the increasing incidence of diabetes mellitus in the Arab world, specifically in the Kingdom of Saudi Arabia, the rate of amputation will rise significantly. A diabetic foot care program was implemented at King Abdulaziz Medical City in Riyadh, Saudi Arabia, in 2002. The program was directed at health care staff and patients to increase their awareness about diabetic foot care and prevention of complications. The purpose of this study was to perform a primary evaluation of the program’s impact on the rate of lower extremity amputation due to diabetic foot complications.Method: This pilot study was the first analysis of the diabetic foot care program and examined two groups of participants for comparison, ie, a “before” group having had diabetic foot ulcers managed between 1983, when the hospital was first established, and 2002 when the program began and an “after group” having had foot ulcers managed between 2002 and 2004, in the program’s initial phase. A total of 41 charts were randomly chosen retrospectively. A data sheet containing age, gender, medical data, and the presentation, management, and outcome of diabetic foot cases was used for the analysis.Results: The before group contained 20 patients (17 males and the after group contained 21 patients (16 males. There was no difference between the two groups with regard to age and comorbidities. The rate of amputation was 70% in the before group and 61.9% in the after group. There was a decrease in the percentage of toe amputation in the after group and an increase in the percentage of below-knee amputation in the before group. However, these changes were not significant.Conclusion: The program, although evaluated at an early

Diabetic foot wounds, particularly those secondary to amputation, are very complex and difficult to treat. We investigated whether negative pressure wound therapy (NPWT) improves the proportion and rate of wound healing after partial foot amputation in patients with diabetes. We enrolled 162 patients into a 16-week, 18-centre, randomised clinical trial in the USA. Inclusion criteria consisted of partial foot amputation wounds up to the transmetatarsal level and evidence of adequate perfusion. Patients who were randomly assigned to NPWT (n=77) received treatment with dressing changes every 48 h. Control patients (n=85) received standard moist wound care according to consensus guidelines. NPWT was delivered through the Vacuum Assisted Closure (VAC) Therapy System. Wounds were treated until healing or completion of the 112-day period of active treatment. Analysis was by intention to treat. This study has been registered with , number NCT00224796. More patients healed in the NPWT group than in the control group (43 [56%] vs 33 [39%], p=0.040). The rate of wound healing, based on the time to complete closure, was faster in the NPWT group than in controls (p=0.005). The rate of granulation tissue formation, based on the time to 76-100% formation in the wound bed, was faster in the NPWT group than in controls (p=0.002). The frequency and severity of adverse events (of which the most common was wound infection) were similar in both treatment groups. NPWT delivered by the VAC Therapy System seems to be a safe and effective treatment for complex diabetic foot wounds, and could lead to a higher proportion of healed wounds, faster healing rates, and potentially fewer re-amputations than standard care.

To investigate the therapeutic method and effectiveness of multiple sternocleidomastoid head amputation for adult congenital muscular torticollis. Between March 2009 and February 2011, 19 patients with congenital muscular torticollis were treated with multiple sternocleidomastoid head amputation. There were 13 males and 6 females, aged 16-32 years (mean, 23.5 years). The X-ray films showed that 12 cases were accompanied with some extent cervical lateral bending and wedge change. Ten patients were with ipsilateral facial bradygenesis. Four patients had received single sternocleidomastoid head amputation. All of the 19 patients were treated with multiple sternocleidomastoid head amputation, then plaster support and neck collar were used after operation for 3-6 months. The wounds of all the 19 patients healed primarily, without infection or hematoma. Sixteen patients were followed up 5 months to 2 years (mean, 8 months). The head and neck malformations were ameliorated significantly. The effectiveness was assessed 2 weeks later, in 7 patients without cervical vertebral malformation results were excellent; in 12 patients with cervical vertebral malformation, the results were excellent in 1 case, good in 7 cases, and fair in 4 cases. The length between mastoid process and sternoclavicular joints was elongated (1.88 +/- 0.30) cm significantly after operation in patients without cervical vertebral malformation (t = 6.24, P = 0.00), showing no significant difference when compared with normal value (t = 1.87, P = 0.11); the length was elongated (3.38 +/- 0.30) cm significantly (t = 11.37, P = 0.00) after operation in patients with cervical vertebral malformation, but it was significant shorter than normal value (t = 12.19, P = 0.00). Multiple sternocleidomastoid head amputation is a safe and effective method for adult congenital muscular torticollis, which can improve the neck rotation function.

Where should a laminoplasty start? The effect of the proximal level on post-laminoplasty loss of lordosis.

Michael, Keith W; Neustein, Thomas M; Rhee, John M

2016-06-01

Open-door laminoplasty is a useful operation in the surgical management of cervical myelopathy with favorable outcomes and relatively low complications. One potential undesirable outcome is a decrease in cervical lordosis postoperatively. It is unknown whether the most proximal level undergoing laminoplasty affects the magnitude of loss of lordosis. This study aimed to compare the loss of cervical lordosis postoperatively in patients for whom the most proximal level undergoing laminoplasty is C3 versus C4. A retrospective radiographic review at an academic center was carried out. A total of 65 patients at a single institution who underwent plated open door laminoplasty for cervical myelopathy by multiple surgeons over a 5-year period were included. The primary outcome was change in cervical lordosis, which was the difference in C2-T1 Cobb angle between the postoperative and preoperative films. Patients were divided into two groups based on the most proximal vertebral level undergoing laminoplasty. There were 49 patients who underwent laminoplasty beginning at C3, whereas 16 patients underwent laminoplasty beginning at C4. The C2-T1 Cobb angle was measured on the preoperative film and on the final postoperative follow-up film. The difference between these values was calculated for each patient, and the mean of the differences for the C3 group was compared with that of the C4 group. When C3 was the proximal plated laminoplasty level, loss of lordosis averaged 9°. In contrast, when C4 was the proximal plated level, loss of lordosis was significantly less and averaged only 3° (p=.047). In the group as a whole, mean preoperative lordosis was 18° compared with 11° postoperatively, for an overall 7° loss of lordosis. Starting the laminoplasty at C4 led to significantly less loss of lordosis than starting at C3. When the pattern of spinal cord compression does not require laminoplasty at C3, consideration should be given to making C4 the most cephalad laminoplasty

Lower extremity vascular trauma (LEVT) is a major cause of amputation. A clear understanding of prognostic factors for amputation is important to inform surgical decision-making, patient counselling and risk stratification. The aim was to develop an understanding of prognostic factors for amputation following surgical repair of LEVT. A systematic review was conducted to identify potential prognostic factors. Bayesian meta-analysis was used to calculate an absolute (pooled proportion) and relative (pooled odds ratio, OR) measure of the amputation risk for each factor. Forty-five studies, totalling 3187 discrete LEVT repairs, were included. The overall amputation rate was 10·0 (95 per cent credible interval 7·4 to 13·1) per cent. Significant prognostic factors for secondary amputation included: associated major soft tissue injury (26 versus 8 per cent for no soft tissue injury; OR 5·80), compartment syndrome (28 versus 6 per cent; OR 5·11), multiple arterial injuries (18 versus 9 per cent; OR 4·85), duration of ischaemia exceeding 6 h (24 versus 5 per cent; OR 4·40), associated fracture (14 versus 2 per cent; OR 4·30), mechanism of injury (blast 19 per cent, blunt 16 per cent, penetrating 5 per cent), anatomical site of injury (iliac 18 per cent, popliteal 14 per cent, tibial 10 per cent, femoral 4 per cent), age over 55 years (16 versus 9 per cent; OR 3·03) and sex (men 7 per cent versus women 8 per cent; OR 0·64). Shock and nerve or venous injuries were not significant prognostic factors for secondary amputation. A significant proportion of patients who undergo lower extremity vascular trauma repair will require secondary amputation. This meta-analysis describes significant prognostic factors needed to inform surgical judgement, risk assessment and patient counselling. © 2015 BJS Society Ltd Published by John Wiley & Sons Ltd.

To study the clinical effect of root amputation in the treatment of periodontal/alveolar abscess teeth with one severe lesion root. 30 periodontal/alveolar abscess teeth with one severe lesion root were chosen in the study. After root canal treatment, supragingival scaling, subgingival scaling and root planning, occlusal adjustment were done. Then the teeth were treated by root amputation. The clinical effect was evaluated 3 months, 6 months and 1 year after surgery. One year after surgery, 27 of 30 teeth were successful, 1 mandibular molar occurred root fracture, 1 mandibular molar was removed because of tooth loosening secondary to periodontal damage. 1 patient lost. Root amputation is an effective solution of periodontal/alveolar abscess.

Full Text Available Background: The purpose of the present study was to evaluate the clinical utility of Mangled extremity severity score (MESS in severely injured lower limbs. Materials and Methods: Retrospectively 25 and prospectively 36 lower limbs in 58 patients with high-energy injuries were evaluated with the use of MESS, to assist in the decision-making process for the care of patients with such injuries. Difference between the mean MESS scores for amputated and salvaged limbs was analyzed. Results: In the retrospective study 4.65 (4.65 ± 1.32 was the mean score for the salvaged limbs and 8.80 (8.8 ± 1.4 for the amputated limbs. In the prospective study 4.53 (4.53 ± 2.44 was the mean score for the salvaged limbs and 8.83 (8.83 ± 2.34 for the amputated limbs. There was a significant difference in the mean scores for salvaged and amputated limbs. Retrospective 21 (84% and prospective 29 (80.5% limbs remained in the salvage pathway six months after the injury. Conclusion: MESS could predict amputation of severely injured lower limbs, having score of equal or more than 7 with 91% sensitivity and 98% specificity. There was a significant difference in the mean MESS scores in the prospective study (n=36, 4.53 (4.53 ± 2.44 in thirty salvaged limbs (83.33% and 8.83 (8.83 ± 2.34 in six amputated limbs (16.66% with a P -value 0.002 ( P -value < 0.01. Similarly there was a significant difference in the mean MESS score in the retrospective study (n=25, 4.65 (4.65 ± 1.32 in twenty salvaged limbs (80% and 8.80 (8.8 ± 1.4 in five amputated limbs (20% with a P -value 0.00005 ( P -value < 0.01. MESS is a simple and relatively easy and readily available scoring system which can help the surgeon to decide the fate of the lower extremity with a high-energy injury.

Management of nerves during leg amputation--a neglected area in our understanding of the pathogenesis of phantom limb pain.

Science.gov (United States)

Rasmussen, S; Kehlet, H

2007-09-01

Chronic neuropathic pain after leg amputation is a significant problem, with a reported incidence during the first year as high as 70%. Intra-operative handling of the nerves during amputation has not been discussed in the literature on post-amputation pain and, in major textbooks, it is recommended that the ischial nerve be ligated, despite the fact that the experimental literature uses nerve ligations to produce neuropathic pain. The purpose of this study was to investigate the clinical practice of nerve handling during leg amputation. Trainees with at least 2 years of practice received a questionnaire regarding handling of the nerves during leg amputation; 128 of 149 questionnaires sent (86%) were returned. Ligation of the nerves was used by 31% of surgeons. There is no consistency in the management of the large nerves during lower leg amputation. The recommendations in major textbooks may not be appropriate when compared with the experimental literature on nerve ligature models to produce neuropathic pain. Future studies on post-amputation pain should consider intra-operative nerve management.

2013-08-01

Full Text Available PURPOSE: Although functional differences have been described between patients with lower extremity bone sarcoma with amputation and limb preservation surgery, differences have not clearly been shown between the two groups related to quality of life. The aim of the study was to determine if there is a difference in overall quality of life in lower extremity bone sarcoma survivors related to whether they had an amputation or a limb preservation procedure. PATIENTS AND METHODS: Eighty-two long-term survivors of lower extremity bone sarcoma were studied to make a comparison of the overall quality of life, pain assessment and psychological evaluations in limb preservation and amputation patients. Forty-eight patients with limb preservation and thirty-four patients with amputations were enrolled in the study. Validated psychometric measures including the Quality of Life Questionnaire, the Minnesota Multiphasic Personality Inventory and visual analog scales were utilized.RESULTS: The overall quality of life of patients with limb preservation was significantly higher than patients with amputation (p-value < 0.01. Significant differences were noted in the categories of material well being, job satisfiers and occupational relations. CONCLUSION: The overall quality of life of patients with limb preservation appears to be better than for those patients with amputation based on the quality of life questionnaire in patients surviving lower extremity bone sarcoma. Further analysis needs to verify the results and focus on the categories that significantly affect the overall quality of life.

Objective: (1) Develop a standardized approach to quantitatively measure residual limb skin health. (2) Report reference residual limb skin health values in people with transtibial and transfemoral amputation. Approach: Residual limb health outcomes in individuals with transtibial ( n  = 5) and transfemoral ( n  = 5) amputation were compared to able-limb controls ( n  = 4) using noninvasive imaging (hyperspectral imaging and laser speckle flowmetry) and probe-based approaches (laser doppler flowmetry, transcutaneous oxygen, transepidermal water loss, surface electrical capacitance). Results: A standardized methodology that employs noninvasive imaging and probe-based approaches to measure residual limb skin health are described. Compared to able-limb controls, individuals with transtibial and transfemoral amputation have significantly lower transcutaneous oxygen tension, higher transepidermal water loss, and higher surface electrical capacitance in the residual limb. Innovation: Residual limb health as a critical component of prosthesis rehabilitation for individuals with lower limb amputation is understudied in part due to a lack of clinical measures. Here, we present a standardized approach to measure residual limb health in people with transtibial and transfemoral amputation. Conclusion: Technology advances in noninvasive imaging and probe-based measures are leveraged to develop a standardized approach to quantitatively measure residual limb health in individuals with lower limb loss. Compared to able-limb controls, resting residual limb physiology in people that have had transfemoral or transtibial amputation is characterized by lower transcutaneous oxygen tension and poorer skin barrier function.

Reamed intramedullary (IM) screw fixation for proximal fifth metatarsal fractures is technically challenging with potentially devastating complications if basic principles are not followed. A case of an iatrogenic fourth-degree burn after elective reamed IM screw fixation of a proximal fifth metatarsal fracture in a high-level athlete is reported. The case was complicated by postoperative osteomyelitis with third-degree soft-tissue defect. This was successfully treated with staged autologous bone graft reconstruction, tendon reconstruction, and local bi-pedicle flap coverage. The patient returned to competitive-level sports, avoiding the need for fifth ray amputation. Critical points of the IM screw technique and definitive reconstruction are discussed. Bulk autograft reconstruction is a safe and effective alternative to ray amputation in segmental defects of the fifth metatarsal.Level of evidence V.

An Approach to Transmetatarsal Amputation to Encourage Immediate Weightbearing in Diabetic Patients.

Science.gov (United States)

Canales, Michael B; Heurich, Maureen E; Mandela, Ashley M; Razzante, Mark C

Transmetatarsal amputation remains the standard treatment for the unsalvageable diabetic forefoot; however, this operation is often complicated by wound dehiscence, ulceration, and the need for additional surgery and tendon balancing. The technique described in the present report provides an uncomplicated suturing method for closure of a standard transmetatarsal amputation. A drill hole is created through the first, second, and fourth metatarsals, which facilitates added stability to the plantar flap of the residual metatarsals. The patients are encouraged to begin protected weightbearing as early as the first postoperative day. The security of the flap promotes immediate weightbearing, which could result in fewer postoperative complications of transmetatarsal amputations. Early weightbearing will not only encourage tendon rebalancing, but also could improve angiogenesis through capillary ingrowth. Copyright © 2017 American College of Foot and Ankle Surgeons.

Penile amputation is a rare catastrophe and a serious complication of circumcision. Reconstruction of the glans penis may be indicated following amputation. Our report discusses a novel technique for reconfiguration of an amputated glans penis 1 year after a complicated circumcision. A 2-year-old male infant presented to us with glans penis amputation that had occurred during circumcision 1 year previously. The parents complained of severe meatal stenosis with disfigurement of the penis. Penis length was 3 cm. Complete penile degloving was performed. The distal part of the remaining penis was prepared by removing fibrous tissue. A buccal mucosal graft was applied to the distal part of the penis associated with meatotomy. The use of a buccal mucosal graft is a successful and simple procedure with acceptable cosmetic and functional results for late reconfiguration of the glans penis after amputation when penile size is suitable.

To assess changes in diabetic lower-extremity amputation rates in a defined relatively static population over an 11-year period following the introduction of a multidisciplinary foot team. All diabetic patients with foot problems admitted to Ipswich Hospital, a large district general hospital, were identified by twice-weekly surveillance of all relevant in-patient areas and outcomes including amputations recorded. The incidence of major amputations fell 62%, from 7.4 to 2.8 per 100,000 of the general population. Total amputation rates also decreased (40.3%) but to a lesser extent due to a small increase in minor amputations. Expressed as incidence per 10,000 people with diabetes, total amputations fell 70%, from 53.2 to 16.0, and major amputations fell 82%, from 36.4 to 6.7. Significant reductions in total and major amputation rates occurred over the 11-year period following improvements in foot care services including multidisciplinary team work.

Proximal and Distal Predictors of the Spider Monkey's Stress Levels in Fragmented Landscapes.

José D Ordóñez-Gómez

Full Text Available The rapid loss, fragmentation and degradation of tropical forests threaten the survival of many animal species. However, the way in which these phenomena affect animal health has been poorly explored, thus limiting the design of appropriate conservation strategies. To address this, here we identified using linear mixed models the effect of proximal (diet, activity pattern, hunting and logging and distal (sum of the basal areas of fruiting-tree species [SBAFS], landscape forest cover and degree of forest fragmentation variables over fecal glucocorticoid metabolite (fGCM levels-hormones associated with animal health and fitness-of six groups of spider monkeys (Ateles geoffroyi inhabiting six landscapes with different spatial structures in Mexico. Proximal variables showed a stronger predictive power over fGCMs than distal. In this sense, increases in travel time, the occurrence of hunting, and reductions in rest time and fruit consumption resulted in higher fGCM levels. Regarding distal variables, increases in SBAFS were negatively related to fGCM levels, thus suggesting that food scarcity increases stress hormone levels. Nevertheless, contrary to theoretical expectations, spider monkeys living in smaller tracts of forest spent less time travelling, but the same time feeding on fruit as those in more forested areas. The lower net energy return associated with this combination of factors would explain why, contrary to theoretical expectations, increased forest cover was associated with increased levels of fGCMs in these groups. Our study shows that, at least in the short term, spider monkeys in fragmented landscapes do not always present higher levels of stress hormones compared to those inhabiting continuous forest, and the importance of preserving fruit sources and controlling hunting for reducing the levels of stress hormones in free ranging spider monkeys.

No criteria, including preamputation vascular diagnostic thresholds, have been established to reliably predict healing versus nonhealing following minor lower extremity amputations. Thus, the goal of our study was to identify clinical factors, including noninvasive vascular laboratory measures, associated with wound healing following toe, forefoot, and midfoot amputations. We retrospectively examined records of patients receiving elective toe, forefoot, or midfoot amputation at our institution over a 5-year span (2010-2015). A total of 333 amputations received noninvasive vascular assessment of the lower extremity preamputation and follow-up at 90 days postamputation. Multivariate binomial logistic regression was used to identify variables predicting wound healing as defined as the absence of reamputation due to wound breakdown. Wound healing occurred in 81% of amputations. A total of 23 (7%) patients required revisions of the foot while 39 (12%) patients required major amputations by 90 days. Chi-squared analysis found that toe pressure at or above the value of 47 mm Hg (P = 0.04), bi/triphasic anterior tibial (P = 0.01), and posterior tibial artery (P = 0.01) waveforms were associated with wound healing. When these diagnostic parameters were examined in the presence of confounders (increasing age, chronic kidney disease, and concomitant revascularization), only toe pressure ≥ 47 mm Hg predicted amputation site healing (odds ratio: 3.1 [95% CI: 1.0-9.4], P = 0.04). Preamputation toe pressures of 47 mm Hg and above are associated with wound healing. No other noninvasive vascular studies predicted wound healing in the presence of confounders. Thus, toe pressures may assist in clinical decision-making and should be routinely obtained preamputation. Copyright © 2017 Elsevier Inc. All rights reserved.

Digital injuries are common and frequently complicate occupational hazards and trauma. The management of these injuries often necessitates digital amputation, and a variety of different amputation techniques are advocated and employed by hand surgeons. In this survey study, we investigate the variation in technical detail among a group of hand surgeons when performing digital amputations, specifically the preferred management of the residual articular cartilage, transected nerves, and phalangeal contouring. We reviewed the literature on techniques in digital amputation and created a 7-question survey that targeted controversial issues within this specific topic. We then sent this survey electronically to the members of the American Society for Surgery of the Hand and reviewed the responses of the respondents (n = 592, 20%). There was a mixed response regarding whether or not to remove the articular cartilage when disarticulating, nearly a 50% split between the respondents. Most would perform a "pull and resect" technique for transected nerves. Phalangeal contouring was generally agreed upon, though the technique in doing so varied from performing condylectomies, to bony contouring only, to some combination of both. We detected a substantial variation in technique among our group of hand surgeons regarding the treatment of articular cartilage and the method of phalangeal contouring. There was more consensus regarding the treatment of transected nerve. It is interesting that to date, the aforementioned issues in digital amputation have not been critically evaluated by definitive and well-controlled studies.

individuals had a decrease in performance on both tasks; however, the gait task was prioritized for the majority (56.2%) of participants. Cognitive distractions while walking pose challenges to individuals regardless of etiology, level of amputation, or time with the prosthesis. These findings highlight that individuals are at risk for adverse events when performing multiple tasks while walking. ▪▪▪. Copyright © 2018 American Academy of Physical Medicine and Rehabilitation.

The distal blood pressure predicts healing of amputations on the feet

DEFF Research Database (Denmark)

Holstein, P

1984-01-01

The healing of digital and transmetatarsal forefoot amputations was compared with the systolic digital and ankle blood pressure, both measured with a strain-gauge, and with the skin perfusion pressure on the forefoot measured with the isotope washout technique. In 85 out of 134 legs (63 per cent......) the amputation healed. The frequency of healing correlated statistically significantly with all three measures of distal blood pressures, the closest correlation being with the systolic digital blood pressure (SDBP). As measured in 110 cases the healing rates were: SDBP less than 20 mm Hg: four out of 23; SDBP...

Amputation rates during recent military conflicts were at an all-time high, but medical treatment of those amputations and attitudes of service members to get back to duty are also surging ahead. We present the cases of an active duty rescue C130 pilot with an above-the-knee amputation and a retired army sergeant with a below-the-knee amputation. Successful rehabilitation was augmented in both cases by using negative pressure incorporated in a custom prosthetic socket to accelerate incision closure, improve self-efficacy in wound care, and self-management, ultimately leading to faster recovery times, full engagement of the rehabilitation process, and return to active duty.

Individual Leg and Joint Work during Sloped Walking for People with a Transtibial Amputation Using Passive and Powered Prostheses

Full Text Available People with a transtibial amputation using passive-elastic prostheses exhibit reduced prosthetic ankle power and push-off work compared to non-amputees and compensate by increasing their affected leg (AL hip joint work and unaffected leg (UL ankle, knee, and hip joint and leg work during level-ground walking. Use of a powered ankle–foot prosthesis normalizes step-to-step transition work during level-ground walking over a range of speeds for people with a transtibial amputation, but the effects on joint work during level-ground, uphill, and downhill walking have not been assessed. We investigated how use of passive-elastic and powered ankle–foot prostheses affect leg joint biomechanics during level-ground and sloped walking. 10 people with a unilateral transtibial amputation walked at 1.25 m/s on a dual-belt force-measuring treadmill at 0°, ±3°, ±6°, and ±9° using their own passive-elastic and a powered prosthesis (BiOM T2, BionX Medical Technologies, Inc., Bedford, MA, USA while we measured kinematic and kinetic data. We calculated AL and UL prosthetic, ankle, knee, hip, and individual leg positive, negative, and net work. Use of a powered compared to passive-elastic ankle–foot prosthesis resulted in greater AL prosthetic and individual leg net work on uphill and downhill slopes. Over a stride, AL prosthetic positive work was 23–30% greater (p < 0.05 during walking on uphill slopes of +6°, and +9°, prosthetic net work was up to 10 times greater (more positive (p ≤ 0.005 on all uphill and downhill slopes and individual leg net work was 146 and 82% more positive (p < 0.05 at uphill slopes of +6° and +9°, respectively, with use of the powered compared to passive-elastic prosthesis. Greater prosthetic positive and net work through use of a powered ankle–foot prosthesis during uphill and downhill walking improves mechanical work symmetry between the legs, which could decrease metabolic cost and improve functional

Management of patients with brachial plexus injuries requires a team approach so that all aspects of their care are addressed simultaneously. This report examines elective amputation and prosthetic rehabilitation in a patient with brachial plexus avulsion of the left arm. The best possibility for good prosthetic rehabilitation is the early application of prosthetic devices with intensive occupational therapy. Using this type of approach, we have achieved significant improvement in amputation rehabilitation of upper extremity amputees treated with immediate postoperative conventional electric and myoelectric prostheses.

Prior studies have identified age as a factor in determining an individual's likelihood of receiving a prosthesis following a lower limb amputation. These studies are limited to specific subsets of the general population and are unable to account for preamputation characteristics within their study populations. Our study seeks to determine the effect of preamputation characteristics on the probability of receiving a prosthesis for the general population in the United States. To identify preamputation characteristics that predict of the likelihood of receiving a prosthesis following an above-knee amputation. A retrospective, population-based cohort study. Olmsted County, Minnesota (2010 population: 144,248). Individuals (n = 93) over the age of 18 years who underwent an above-knee amputation, that is, knee disarticulation or transfemoral amputation, while residing in Olmsted County, MN, between 1987 and 2013. Characteristics affecting the receipt of a prosthesis were analyzed using a logistic regression and a random forest algorithm for classification trees. Preamputation characteristics included age, gender, amputation etiology, year of amputation, mobility, cognitive ability, comorbidities, and time between surgery and the prosthesis decision. The association of preamputation characteristics with the receipt of a prosthesis following an above-knee amputation. Twenty-four of the participants received a prosthesis. The odds of receiving a prosthesis were almost 30 times higher in those able to walk independently prior to an amputation relative to those who could not walk independently. A 10-year increase in age was associated with a 53.8% decrease in the likelihood of being fit for a prosthesis (odds ratio = 0.462, P =.030). Time elapsed between surgery and the prosthesis decision was associated with a rise in probability of receiving a prosthesis for the first 3 months in the random forest algorithm. No other observed characteristics were associated with receipt

Full Text Available OBJECTIVE: The clinical implication of the coronary artery calcium score (CS is well demonstrated. However, little is known about the association between lower extremity arterial calcification and clinical outcomes. METHODS AND RESULTS: Eighty-two patients with symptomatic peripheral artery disease (age 61.0±12.4 years were followed for 21±11 months. CSs, ranging from the common iliac artery bifurcation to the ankle area, were analyzed through noncontrast multidetector computed tomography images retrospectively. The primary endpoints of this study were amputation and mortality. Old age, diabetes, hyperlipidemia, and end-stage renal disease were associated with higher CSs. Patients with more advanced Fontaine stages also tended to have significantly higher CSs (p = 0.03. During the follow-up period (21±11 months, 29 (35% patients underwent amputation, and 24 (29% patients died. Among the patients who underwent amputation, there were no significant differences in CSs between the amputated legs and the non-amputated legs. In the Cox proportional hazard model with CS divided into quartiles, patients with CS in the highest quartile had a 2.88-fold (95% confidence interval [CI] 1.18-12.72, p = 0.03 and a 5.16-fold (95% CI 1.13-21.61, p = 0.04 higher risk for amputation and all-cause mortality, respectively, than those with CS in the lowest quartile. These predictive effects remained after conventional risk factor adjustment. CONCLUSION: Lower extremity arterial CSs are associated with disease severity and outcomes, including amputation and all-cause mortality, in patients with symptomatic peripheral artery disease. However, the independent predictive value needs further investigation in large scale, prospective studies.

A frequently-seen injury pattern in current military experience is traumatic lower limb amputation as a result of improvised explosive devices (IEDs). This injury can coexist with fractures involving the pelvic ring. This study aims to assess the frequency of concomitant pelvic fracture in IED-related lower limb amputation. A retrospective analysis of the trauma charts, medical notes, and digital imaging was undertaken for all patients arriving at the Emergency Department at the UK military field hospital in Camp Bastion, Afghanistan, with a traumatic lower limb amputation in the six months between September 2009 and April 2010, in order to determine the incidence of associated pelvic ring fractures. Of 77 consecutive patients with traumatic lower limb amputations, 17 (22%) had an associated pelvic fracture (eleven with displaced pelvic ring fractures, five undisplaced fractures and one acetabular fracture). Unilateral amputees (n = 31) had a 10% incidence of associated pelvic fracture, whilst 30 % of bilateral amputees (n = 46) had a concurrent pelvic fracture. However, in bilateral, trans-femoral amputations (n = 28) the incidence of pelvic fracture was 39%. The study demonstrates a high incidence of pelvic fractures in patients with traumatic lower limb amputations, supporting the routine pre-hospital application of pelvic binders in this patient group.

Marco Antonio Nunes

Full Text Available CONTEXT AND OBJECTIVE: Lower-limb amputation compromises patients' independence and autonomy, and therefore they should be referred for rehabilitation in order to adapt to prostheses and regain autonomy. The aim here was to assess adaptation to prostheses among patients with major lower-limb amputations and its association with sociodemographic and clinical data. DESIGN AND SETTING: This was a cross-sectional study in the city of Aracaju, Brazil. METHODS: The patients were identified by primary healthcare teams. The inclusion criterion was that these should be patients who underwent major lower-limb amputations of any etiology. Associations between sociodemographic and clinical variables and the adaptation to lower-limb prostheses were assessed. RESULTS: 149 patients were examined. Adaptation to the prosthesis occurred in 40% (60/149 of them, but only 62% (37/60 were using it. Adaptation occurred more often among male patients (P = 0.017 and among those who had a higher educational level (P = 0.013, with a longer time since amputation (P = 0.049 and when the etiology was trauma (P = 0.003. The result from logistic regression analysis showed that only patients with low education (P = 0.031 were significantly associated with a lower frequency of adaptation to prostheses. CONCLUSION: It was found that patients with a low educational level became adapted to the prosthesis less frequently. CONTEXTO E OBJETIVO: A amputação de membros inferiores compromete a independência e a autonomia dos pacientes, por isso, eles devem ser encaminhados para a reabilitação para a adaptação das próteses e assim viabilizar a recuperação da autonomia.

Cross-sectional study. A university physical therapy amputee clinic. Participants (N=55) were included if they (1) were aged ≥18 years with a unilateral transfemoral or transtibial amputation; (2) were classified as K3 or K4 functional level; (3) completed all relevant outcome measures; and (4) were currently using a prosthesis. Not applicable.

K level was determined by group consensus based on a standardized clinical evaluation. After controlling for covariates, patients classified as K3 had slower TUG times (P=.002) and self-selected and fast gait speeds (Pclinical evaluations to help differentiate between individuals of higher functional mobility. The LCI and PEQ-MS may be less useful in classifying individuals as K3 versus K4 because of a ceiling effect. Copyright © 2018 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

2018-06-01

Inhibitors of the sodium-glucose co-transporter-2 (SGLT-2) are a novel class of glucose-lowering agents that show promising results. However, the use of canagliflozin has been associated with an increased risk of lower-limb amputation. Whether this risk concerns other SGLT-2 inhibitors is unclear, and our objective was to address this issue. We performed a disproportionality analysis using the WHO global database of individual case safety reports (VigiBase). Among the 8 293 886 reports available between January 2013 and December 2017, we identified 79 reports of lower-limb amputation that were associated with SGLT-2 inhibitors. Among all blood glucose lowering drugs, the proportional reporting ratio (PRR) was increased only for SGLT-2 inhibitors (5.55 [4.23, 7.29]). While we observed an expected signal for canagliflozin (7.09 [5.25, 9.57]), the PRR was also high for empagliflozin (4.96 [2.89, 8.50]) and, for toe amputations only, for dapagliflozin (2.62 [1.33, 5.14]). In conclusion, our results reveal a positive disproportionality signal for canagliflozin, and also for empagliflozin, and, for toe amputations only, for dapagliflozin. However, our analysis relies on a limited number of cases and is exposed to the biases inherent to pharmacovigilance studies. Further prospective data are therefore needed to better characterize the risk of amputations with different SGLT-2 inhibitors. © 2018 John Wiley & Sons Ltd.

Full Text Available Aim. In two German regions with 11.1 million inhabitants, 6 networks for specialized treatment of DFS were implemented until 2008. Data provided for accounting purposes was analysed in order to determine changes in the rate of diabetics requiring amputations in the years before and after the implementation. Method. Data covering 2.9 million people insured by the largest insurance company between 2007 and 2013 was analysed by the use of log-linear Poisson regression adjusted for age, gender and region. Results. The rate of diabetics needing major amputations fell significantly by 9.5% per year (p<0.0001 from 217 to 126 of 100,000 patients per year. The rate of diabetics needing amputations of any kind fell from 504 to 419 of 100,000 patients per year (p=0.0038. Discussion. The networks integrate health care providers in an organised system of shared care. They educate members of the medical community and the general public. At the same time, a more general disease management program for people with diabetes was implemented, which may also have contributed to this decrease. At the end of the observation period, the rate of diabetics requiring amputations was still high. For this reason, further expansion of organised specialized care is urgently needed.

Patients with amputation need prosthesis to comfortably move around. One of the most important parts of a good prosthesis is the socket. Currently, the most commonly used method is the traditional socket manufacturing method, which involves manual work; however, computer-aided design/computer-aided manufacturing (CAD/CAM) is also being used in the recent years. The present study aimed to investigate the effects of sockets manufactured by traditional and CAD/CAM method on clinical characteristics and quality of life of patients with transtibial amputation. The study included 72 patients with transtibial amputation using prosthesis, 36 of whom had CAD/CAM prosthetic sockets (group 1) and 36 had traditional prosthetic sockets (group 2). Amputation reason, prosthesis lifetime, walking time and distance with prosthesis, pain-free walking time with prosthesis, production time of the prosthesis, and adaptation time to the prosthesis were questioned. Quality of life was assessed using the 36-item Short Form Health Survey questionnaire and the Trinity Amputation and Prosthesis Experience Scales. Walking time and distance and pain-free walking time with prosthesis were significantly better in group 1 than those in group 2. Furthermore, the prosthesis was applied in a significantly shorter time, and socket adaptation time was significantly shorter in group 1. Except emotional role limitation, all 36-item Short Form Healthy Survey questionnaire parameters were significantly better in group 1 than in group 2. Trinity Amputation and Prosthesis Experience Scales activity limitation scores of group 1 were lower, and Trinity Amputation and Prosthesis Experience Scales satisfaction with the prosthesis scores were higher than those in group 2. Our study demonstrated that the sockets manufactured by CAD/CAM methods yield better outcomes in quality of life of patients with transtibial amputation than the sockets manufactured by the traditional method.

Sensory cortical re-mapping following upper-limb amputation and subsequent targeted reinnervation: A case report

Jun Yao

2015-01-01

Full Text Available This case study demonstrates the change of sensory cortical representations of the residual parts of the arm in an individual who underwent a trans-humeral amputation and subsequent targeted reinnervation (TR. As a relatively new surgical technique, TR restores a direct neural connection from amputated sensorimotor nerves to specific target muscles. This method has been successfully applied to upper-limb and lower-limb amputees, and has shown effectiveness in regaining control signals via the newly re-innervated muscles. Correspondingly, recent study results have shown that motor representations for the missing limb move closer to their original locations following TR. Besides regaining motor control signals, TR also restores the sensation in the re-innervated skin areas. We therefore hypothesize that TR causes analogous cortical sensory remapping that may return closer to their original locations. In order to test this hypothesis, cortical activity in response to sensory-level electrical stimulation in different parts of the arm was studied longitudinally in one amputated individual before and up to 2 years after TR. Our results showed that 1 before TR, the cortical response to sensory electrical stimulation in the residual limb showed a diffuse bilateral pattern without a clear focus in either the time or spatial domain; and 2 2 years after TR, the sensory map of the reinnervated median nerve reorganized, showing predominant activity over the contralateral S1 hand area as well as moderate activity over the ipsilateral S1. Therefore, this work provides new evidence for long-term sensory cortical plasticity in the human brain after TR.

Sequential compression biomechanical device versus primary amputation in patients with critical limb ischemia.

LENUS (Irish Health Repository)

Tawfick, Wael A

2013-10-01

Introduction: Patients with critical limb ischemia (CLI), who are unsuitable for intervention, face the consequence of primary amputation. Sequential compression biomechanical device (SCBD) therapy provides a limb salvage option for these patients. Objectives: To assess the outcome of SCBD in patients with severe CLI who are unsuitable for revascularization. Primary end points were limb salvage and 30-day mortality. Methods: From 2005 to 2012, 189 patients with severe CLI were not suitable for revascularization. In all, 171 joined the SCBD program. We match controlled 75 primary amputations. Results: All patients were Rutherford category 4 or higher. Sustained clinical improvement was 68% at 1 year. Mean toe pressure increased from 19.9 to 35.42 mm Hg, P < .0001. Mean popliteal flow increased from 35.44 to 55.91 cm\\/sec, P < .0001. The 30-day mortality was 0.6%. Limb salvage was 94% at 5 years. Freedom from major adverse clinical events was 62.5%. All-cause survival was 69%. Median cost of managing a primary amputation patient is €29 815 compared to €3985 for SCBD. We treated 171 patients with artassist at a cost of €681 965. However, primary amputation for 75 patients cost €2 236 125. Conclusion: The SCBD therapy is a cost-effective and clinically effective solution in patients with CLI having no option of revascularization. It provides adequate limb salvage while providing relief of rest pain without any intervention.

Diabetes: foot ulcers and amputations.

Science.gov (United States)

Hunt, Dereck L

2011-08-26

Diabetic foot ulceration is full-thickness penetration of the dermis of the foot in a person with diabetes. Severity is classified using the Wagner system, which grades it from 1 to 5. The annual incidence of ulcers among people with diabetes is 2.5% to 10.7% in resource-rich countries, and the annual incidence of amputation for any reason is 0.25% to 1.8%. We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of interventions to prevent foot ulcers and amputations in people with diabetes? What are the effects of treatments in people with diabetes with foot ulceration? We searched: Medline, Embase, The Cochrane Library, and other important databases up to September 2010 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). We found 50 systematic reviews and RCTs that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. In this systematic review, we present information relating to the effectiveness and safety of the following interventions: debridement, human cultured dermis, human skin equivalent, patient education, pressure off-loading with felted foam or pressure-relief half-shoe, pressure off-loading with total-contact or non-removable casts, screening and referral to foot-care clinics, systemic hyperbaric oxygen for non-infected ulcers, systemic hyperbaric oxygen in infected ulcers, therapeutic footwear, topical growth factors, and wound dressings.

The rapid loss, fragmentation and degradation of tropical forests threaten the survival of many animal species. However, the way in which these phenomena affect animal health has been poorly explored, thus limiting the design of appropriate conservation strategies. To address this, here we identified using linear mixed models the effect of proximal (diet, activity pattern, hunting and logging) and distal (sum of the basal areas of fruiting-tree species [SBAFS], landscape forest cover and degree of forest fragmentation) variables over fecal glucocorticoid metabolite (fGCM) levels–hormones associated with animal health and fitness–of six groups of spider monkeys (Ateles geoffroyi) inhabiting six landscapes with different spatial structures in Mexico. Proximal variables showed a stronger predictive power over fGCMs than distal. In this sense, increases in travel time, the occurrence of hunting, and reductions in rest time and fruit consumption resulted in higher fGCM levels. Regarding distal variables, increases in SBAFS were negatively related to fGCM levels, thus suggesting that food scarcity increases stress hormone levels. Nevertheless, contrary to theoretical expectations, spider monkeys living in smaller tracts of forest spent less time travelling, but the same time feeding on fruit as those in more forested areas. The lower net energy return associated with this combination of factors would explain why, contrary to theoretical expectations, increased forest cover was associated with increased levels of fGCMs in these groups. Our study shows that, at least in the short term, spider monkeys in fragmented landscapes do not always present higher levels of stress hormones compared to those inhabiting continuous forest, and the importance of preserving fruit sources and controlling hunting for reducing the levels of stress hormones in free ranging spider monkeys.

In order to evaluate whether overuse has a significant role in rotator cuff tear (RCT) aetiology, we evaluated both shoulders of patients with old unilateral arm amputation expecting a higher rate of RC degeneration in the healthy side. Nineteen males and six females (mean age: 57.3 ± 10.1) with an old (>20 years) unilateral arm amputation were submitted to an MRI of both shoulders. Tendon status and muscle tropism were evaluated according to Sugaya and Fuchs classifications, respectively; the acromion humeral distance was measured. Statistical analysis was performed to verify the prevalence of Sugaya and Fuchs categories in each sides. A significant prevalence of Sugaya type II in the amputated side (p = 0.02) and of type I in the healthy side (p Rotator cuff was healthy in 28 and 52% of amputated and non-amputated side, respectively. The mean acromio-humeral distances of the amputated and healthy side were 0.8 cm (SD: 0.1) and 0.9 cm (SD: 0.1), respectively, (p = 0.02). A significant prevalence of Fuchs type II category in the healthy side (p Cuff tear prevalence in not amputated shoulders, inevitably submitted to functional overload, was not higher than that of coetaneous subjects with two functional upper limbs. Shoulder non-use is a risk factor for rotator cuff tear. As the prevalence of rotator cuff degeneration/tear is higher in the amputee side, non-use is a more relevant risk factor than overuse. In the daily clinical practice, patients with rotator cuff tear should be encouraged to shoulder movement because rotator cuff tendon status could be worsened by disuse. III.

Operant conditioning with biofeedback has been shown to be an effective method to modify neural activity to generate goal-directed actions in a brain-machine interface. It is particularly useful when neural activity cannot be mathematically mapped to motor actions of the actual body such as in the case of amputation. Here, we implement an operant conditioning approach with visual feedback in which an amputated monkey is trained to control a multiple degree-of-freedom robot to perform a reach-to-grasp behavior. A key innovation is that each controlled dimension represents a behaviorally relevant synergy among a set of joint degrees-of-freedom. We present a number of behavioral metrics by which to assess improvements in BMI control with exposure to the system. The use of non-human primates with chronic amputation is arguably the most clinically-relevant model of human amputation that could have direct implications for developing a neural prosthesis to treat humans with missing upper limbs.

Tetanus following replantation of an amputated finger: a case report.

Science.gov (United States)

Hayashida, Kenji; Murakami, Chikako; Fujioka, Masaki

2012-10-08

Tetanus is an infectious disease caused by tetanus toxin produced by Clostridium tetani and induces severe neurological manifestations. We treated a patient who developed tetanus during hospitalization for replantation of an amputated finger. To the best of our knowledge, this is the first published case report of such an entity. A 49-year-old Japanese man had an amputation of his right middle finger at the distal interphalangeal joint region in an accident at work. His middle finger was successfully replanted, but his fingertip was partially necrotized because of crushing and so additional reconstruction with a reverse digital arterial flap was performed 15 days after the injury. Tetanus developed 21 days after replantation of the middle finger, but symptoms remitted via rapid diagnosis and treatment. In replantation after finger trauma with exposure of nerve and blood vessel bundles, concern over injuring nerves and blood vessels may prevent irrigation and debridement from being performed sufficiently; these treatments may have been insufficiently performed in this patient. It is likely that the replanted middle finger partially adhered, and Clostridium tetani colonized the partially necrotized region. Even when there is only limited soil contamination, administration of tetanus toxoid and anti-tetanus immunoglobulin is necessary when the fingers are injured outdoors and the finger nerves and blood vessels are exposed. The drugs should be administered just after replantation if the finger has been amputated. However, if clinicians pay attention to the possibility of tetanus development, treatment can be rapidly initiated.

to evaluate whether bacterial genus is a risk factor for major amputation in patients with diabetic foot and infected ulcer. we conducted a case-control, observational study of 189 patients with infected ulcers in diabetic feet admitted to the Vascular Surgery Service of the Risoleta Tolentino Neves Hospital, from January 2007 to December 2012. The bacteriological evaluation was performed in deep tissue cultures from the lesions and amputation was considered major when performed above the foot'smiddle tarsus. the patients'mean age was 61.9±12.7 years; 122 (64.6%) were men. The cultures were positive in 86.8%, being monomicrobial in 72% of the cases. In patients with major amputation, Acinetobacter spp. (24.4%), Morganella spp. (24.4%), Proteus spp. (23.1%) and Enterococcus spp. (19.2%) were the most frequent types of bacteria. The most commonly isolated species were Acinetobacter baumannii, Morganella morganii, Pseudomonas aeruginosa and Proteus mirabilis. As predictors of major amputation, we identified the isolation of the generaAcinetobacter spp. and Klebsiella spp., serum creatinine ≥1.3mg/dl and hemoglobin creatinina ≥1,3mg/dl e de hemoglobina <11g/dl. os gêneros bacterianos Acinetobacter spp. e Klebsiella spp. identificados nas úlceras infectadas dos pacientes com pé diabético associaram-se a maior incidência de amputação maior.

Shared decision making is a consultative process designed to encourage patient participation in decision making by providing accurate information about the treatment options and supporting deliberation with the clinicians about treatment options. The process can be supported by resources such as decision aids and discussion guides designed to inform and facilitate often difficult conversations. As this process increases in use, there is opportunity to raise awareness of shared decision making and the international standards used to guide the development of quality resources for use in areas of prosthetic/orthotic care. To describe the process used to develop shared decision-making resources, using an illustrative example focused on decisions about the level of dysvascular partial foot amputation or transtibial amputation. Development process: The International Patient Decision Aid Standards were used to guide the development of the decision aid and discussion guide focused on decisions about the level of dysvascular partial foot amputation or transtibial amputation. Examples from these shared decision-making resources help illuminate the stages of development including scoping and design, research synthesis, iterative development of a prototype, and preliminary testing with patients and clinicians not involved in the development process. Lessons learnt through the process, such as using the International Patient Decision Aid Standards checklist and development guidelines, may help inform others wanting to develop similar shared decision-making resources given the applicability of shared decision making to many areas of prosthetic-/orthotic-related practice. Clinical relevance Shared decision making is a process designed to guide conversations that help patients make an informed decision about their healthcare. Raising awareness of shared decision making and the international standards for development of high-quality decision aids and discussion guides is important

The presence of chaos in walking is considered to provide a stable, yet adaptable means for locomotion. This study examined whether lower limb amputation and subsequent prosthetic rehabilitation resulted in a loss of complexity in amputee gait. Twenty-eight individuals with transtibial amputation participated in a 6 week, randomized cross-over design study in which they underwent a 3 week adaptation period to two separate prostheses. One prosthesis was deemed “more appropriate” and the other “less appropriate” based on matching/mismatching activity levels of the person and the prosthesis. Subjects performed a treadmill walking trial at self-selected walking speed at multiple points of the adaptation period, while kinematics of the ankle were recorded. Bilateral sagittal plane ankle motion was analyzed for underlying complexity through the pseudoperiodic surrogation analysis technique. Results revealed the presence of underlying deterministic structure in both prostheses and both the prosthetic and sound leg ankle (discriminant measure largest Lyapunov exponent). Results also revealed that the prosthetic ankle may be more likely to suffer loss of complexity than the sound ankle, and a “more appropriate” prosthesis may be better suited to help restore a healthy complexity of movement within the prosthetic ankle motion compared to a “less appropriate” prosthesis (discriminant measure sample entropy). Results from sample entropy results are less likely to be affected by the intracycle periodic dynamics as compared to the largest Lyapunov exponent. Adaptation does not seem to influence complexity in the system for experienced prosthesis users.

Hand injuries by labor accidents are first rank. It is necessary to have a multidisciplinary medical approach to frequently generated temporary and permanent disabilities that affect costs to an institution and to enterprise. To determine the direct cost (DC) and the indirect cost (IC) of complete and partial amputations in hand caused by labor injuries. An observational study was performed. The data was obtained from labor injuries with amputation of a finger or hand that received multidisciplinary management. The costs were calculated according to the list of Institutional Unit Costs. The IC were obtained with the "safety pays" program. We included 48 cases. The average age was 32.17 years; the cost of surgical operations was $767,470; and the payment of a partial disability permanent was $1,032,670; the DC of the sample of 48 workers was $2,955,007 with an IC of $3,250,507 and a total cost of $6,205,515, the average cost per worker of $51,741 for DC, $56,915 for IC and $108,657 for the total cost. Costs of hand injures requires the creation of prevention programs.

Dysvascular partial foot amputation (PFA) is a common sequel to advanced peripheral vascular disease. Helping inform difficult discussions between patients and practitioners about the level of PFA, or the decision to have a transtibial amputation (TTA) as an alternative, requires an understanding of the current research evidence on a wide range of topics including wound healing, reamputation, quality of life, mobility, functional ability, participation, pain and psychosocial outcomes, and mortality. The aim of this review was to describe a comprehensive range of outcomes of dysvascular PFA and compare these between levels of PFA and TTA. The review protocol was registered in PROSPERO (CRD42015029186). A systematic search of the literature was conducted using MEDLINE, EMBASE, psychINFO, AMED, CINAHL, ProQuest Nursing and Allied Health, and Web of Science. These databases were searched using MeSH terms and keywords relating to different amputation levels and outcomes of interest. Peer reviewed studies of original research-irrespective of the study design-were included if published in English between 1 January 2000, and 31 December 2015, and included discrete cohort(s) with dysvascular PFA or PFA and TTA. Outcomes of interest were rate of wound healing and complications, rate of ipsilateral reamputation, quality of life, functional ability, mobility, pain (i.e., residual limb or phantom pain), psychosocial outcomes (i.e., depression, anxiety, body image and self-esteem), participation, and mortality rate. Included studies were independently appraised by two reviewers. The McMaster Critical Review Forms were used to assess methodological quality and identify sources of bias. Data were extracted based on the Cochrane Consumers and Communication Review Group's data extraction template by a primary reviewer and checked for accuracy and clarity by a second reviewer. Findings are reported as narrative summaries given the heterogeneity of the literature, except for mortality

Workplace amputation is a widespread, disabling, costly, and preventable public health problem. Thousands of occupational amputations occur each year, clustering in particular economic sectors, workplaces, and demographic groups such as young workers, Hispanics, and immigrants. To identify and describe work related amputations amongst Illinois residents that occur within Illinois as reported in three legally mandated State databases; to compare these cases with those identified through the BLS-Survey of Occupational Illnesses and Injuries (SOII); and to determine the extent of direct intervention by the Occupational Safety and Health Administration (OSHA) for these injuries in the State. We linked cases across three databases in Illinois - trauma registry, hospital discharge, and workers compensation claims. We describe amputation injuries in Illinois between 2000 and 2007, compare them to the BLS-SOII, and determine OSHA investigations of the companies where amputations occurred. There were 3984 amputations identified, 80% fingertips, in the Illinois databases compared to an estimated 3637, 94% fingertips, from BLS-SOII. Though the overall agreement is close, there were wide fluctuations (over- and under-estimations) in individual years between counts in the linked dataset and federal survey estimates. No OSHA inspections occurred for these injuries. Increased detection of workplace amputations is essential to targeting interventions and to evaluating program effectiveness. There should be mandatory reporting of all amputation injuries by employers and insurance companies within 24h of the event, and every injury should be investigated by OSHA. Health care providers should recognise amputation as a public health emergency and should be compelled to report. There should be a more comprehensive occupational injury surveillance system in the US that enhances the BLS-SOII through linkage with state databases. Addition of industry, occupation, and work

Pendulating-A grounded theory explaining patients' behavior shortly after having a leg amputated due to vascular disease.

Although the group of vascular leg amputated patients constitutes some of the most vulnerable and frail on the orthopedic wards, previous research of amputated patients has focused on patients attending gait training in rehabilitation facilities leaving the patient experience shortly after surgery unexplored. Understanding patients' behavior shortly after amputation could inform health professionals in regard to how these vulnerable patients' needs at hospital can be met as well as how to plan for care post-discharge. To construct a grounded theory (GT) explaining patients' behavior shortly after having a leg amputated as a result of vascular disease. In line with constructivist GT methodology, data from ethnographic observations and interviews were simultaneously collected and analyzed using the constant comparative method covering the patients' experiences during the first 4 weeks post-surgery. Data collection was guided by theoretical sampling and comprised 11 patients. A GT was constructed. Patients went through a three-phased process as they realized they were experiencing a life-changing event. The first phase was "Losing control" and comprised the sub-categories "Being overwhelmed" and "Facing dependency." The second phase was "Digesting the shock" and comprised the sub-categories "Swallowing the life-changing decision," "Detecting the amputated body" and "Struggling dualism." The third phase was "Regaining control" and comprised the sub-categories "Managing consequences" and "Building-up hope and self-motivation." "Pendulating" was identified as the core category describing the general pattern of behavior and illustrated how patients were swinging both cognitively and emotionally throughout the process. The theory of "Pendulating" offers a tool to understand the amputated patients' behavior and underlying concerns and to recognize where they are in the process. Concepts from the theory could be used by health professionals who support patients coping with

High rates of osteoarthritis of the knee joint of the intact limb in persons with amputation have raised concern about the long-term consequence of running. The purpose of this intervention was to determine if loading of the knee on the intact limb of a person with transtibial amputation during running could be decreased by changing the intact limb initial ground contact from rear foot to forefoot strike. This study compared kinematic, kinetic and temporal-spatial data collected while a 27-year-old male, who sustained a traumatic unilateral transtibial amputation of the left lower extremity, ran using a forefoot ground contact and again while using a heel first ground contact. Changing initial ground contact from rear foot strike to forefoot strike resulted in decreases in vertical ground reaction forces at impact, peak knee moments in stance, peak knee powers, and improved symmetry in step length. This case suggests forefoot initial contact of the intact limb may minimize loading of the knee on the intact limb in individuals with transtibial amputation.

Amputees by choice: body integrity identity disorder and the ethics of amputation.

Science.gov (United States)

Bayne, Tim; Levy, Neil

Should surgeons be permitted to amputate healthy limbs if patients request such operations? We argue that if such patients are experiencing significant distress as a consequence of the rare psychological disorder named Body Integrity Identity Disorder (BIID), such operations might be permissible. We examine rival accounts of the origins of the desire for healthy limb amputations and argue that none are as plausible as the BIID hypothesis. We then turn to the moral arguments against such operations, and argue that on the evidence available, none is compelling. BIID sufferers meet reasonable standards for rationality and autonomy: so as long as no other effective treatment for their disorder is available, surgeons ought to be allowed to accede to their requests.

Tetanus following replantation of an amputated finger: a case report

Tetanus developed 21 days after replantation of the middle finger, but symptoms remitted via rapid diagnosis and treatment. Conclusions In replantation after finger trauma with exposure of nerve and blood vessel bundles, concern over injuring nerves and blood vessels may prevent irrigation and debridement from being performed sufficiently; these treatments may have been insufficiently performed in this patient.

Peri-mortem limb amputations are rarely reported in the paleopathological literature. The cases reported here concern severing of both hands and feet observed in three adult male skeletons, exhumed from the medieval Portuguese necropolis of Rossio do Marquês de Pombal, Estremoz, Portugal. The fact that they were found in the same site, in graves placed side by side, that all are young males, and that the three skeletons show similar perimortem injuries, make this a unique case meriting detailed analysis. Considering the lesions' location and pattern, as well as historical data, we hypothesize that this is a case of amputation as a consequence of judicial punishment. Estremoz was an important city in sustaining the Royal power at a regional scale during the medieval period. Copyright © 2017 Elsevier Inc. All rights reserved.

Surgical reimplantation of penile glans amputation in children during circumcision

Directory of Open Access Journals (Sweden)

Bouassida Khaireddine

2014-01-01

Full Text Available Circumcision is one of the oldest and most commonly performed surgical procedures. Unfortunately, various complications may occur during circumcision, ranging from trivial to tragic such as penile amputation which is a serious complication and a challenging injury to treat. We describe two cases of non-microsurgical successful reattachment of a distal penile glans which were amputated during circumcision. In the first case, a 5-year-old child underwent circumcision by an urologist under local anesthesia. In the second one, a 3-year-old child underwent circumcision by a general practitioner who used to make circumcision. In this article, the literature is reviewed; results and potential complications of this surgery are also discussed. Glans sensation was present, early morning erection was maintained, and there was an erectile response during penile manipulation in both cases. Although circumcision is not technically difficult, it should be taken seriously. The use of microsurgical reattachment is not always possible, especially in pediatric cases; it also requires special equipment and training.

Goebel, Andreas; Lewis, Sarah; Phillip, Rhodri; Sharma, Manohar

2018-01-01

Limb amputation is sometimes being performed in long-standing complex regional pain syndrome (CRPS), although little evidence is available guiding management decisions, including how CRPS recurrence should be managed. This report details the management of a young soldier with CRPS recurrence 2 years after midtibial amputation for CRPS. Conventional spinal cord stimulation did not achieve paraesthetic coverage, or pain relief in the stump, whereas L4 dorsal root ganglion stimulation achieved both coverage and initially modest pain relief, and over time, substantial pain relief. Current evidence does not support the use of amputation to improve either pain or function in CRPS. Before a decision is made, in exceptional cases, about referral for amputation, dorsal root ganglion stimulation should be considered as a potentially effective treatment, even where conventional spinal cord stimulator treatment has failed to achieve reliable paraesthetic cover. Furthermore, this treatment may provide pain relief in those patients with CRPS recurrence in the stump after amputation. © 2017 World Institute of Pain.

Six patients with smashed wound were treated with debridement and amputation, combined with vacuum aspiration in-emergency; 9 patients caused by infection and necrosis were treated with debridement and amputation, combined with vacuum aspiration, and full-thickness skin graft were performed at stage II. The skin defect area of residual limbs ranged from 40 cm x 20 cm to 25 cm x 15 cm. All patients were followed up from 3 months to 1 year. Full-thickness skin graft of residual limbs were survived,and obtained satisfactory walking function with prosthetic. Residual skin increased thicken, wearproof without rupture and pain. Full-thickness skin graft combined with vacuum sealing drainage in treating cutaneous deficiency of traumatic shank amputation stump could reserve the length of residual limbs, increase survival rate of skin graft with less scar of survival skin, get good wearability and it is conducive to prosthetic wear. It is a simple and easy treatment method.

Introduction Although the group of vascular leg amputated patients constitutes some of the most vulnerable and frail on the orthopedic wards, previous research of amputated patients has focused on patients attending gait training in rehabilitation facilities leaving the patient experience shortly after surgery unexplored. Understanding patients’ behavior shortly after amputation could inform health professionals in regard to how these vulnerable patients’ needs at hospital can be met as well as how to plan for care post-discharge. Aim To construct a grounded theory (GT) explaining patients’ behavior shortly after having a leg amputated as a result of vascular disease. Method In line with constructivist GT methodology, data from ethnographic observations and interviews were simultaneously collected and analyzed using the constant comparative method covering the patients’ experiences during the first 4 weeks post-surgery. Data collection was guided by theoretical sampling and comprised 11 patients. A GT was constructed. Results Patients went through a three-phased process as they realized they were experiencing a life-changing event. The first phase was “Losing control” and comprised the sub-categories “Being overwhelmed” and “Facing dependency.” The second phase was “Digesting the shock” and comprised the sub-categories “Swallowing the life-changing decision,” “Detecting the amputated body” and “Struggling dualism.” The third phase was “Regaining control” and comprised the sub-categories “Managing consequences” and “Building-up hope and self-motivation.” “Pendulating” was identified as the core category describing the general pattern of behavior and illustrated how patients were swinging both cognitively and emotionally throughout the process. Conclusion The theory of “Pendulating” offers a tool to understand the amputated patients’ behavior and underlying concerns and to recognize where they are in the

Non-replantable fingertip amputation is still a clinical challenge. We performed modified composite grafting with pulp adipofascial advancement flap for Hirase IIA fingertip amputations. Results from a series of patients are presented and achieved better outcome than traditional composite grafting. From September 2012 to April 2014, fourteen patients with sixteen digits were included in our study. Mean age of patients was 43.9 years (20-71 years). All of our patients underwent this procedure under digital block anesthesia. We performed pulp adipofascial advancement flap for better soft tissue coverage of bone exposure stump first. The amputated parts were defatted, trimming, and reattached as composite graft. Age and gender of patients, injured finger, Hirase classification, mechanism of trauma, overall graft survival area, two-point discrimination (2PD) (mm) at six-month, length of shortening of digit, The average disabilities of the arm, shoulder, and hand (DASH) score and subjective self-evaluation questionnaire at 6 month were recorded. Average graft survival area was 89% (75-100%). Average length of shortening was 2.2 mm (1.8-3.5 mm). 2PD at six-month after surgery was 6.3 mm in average (5-8 mm). Average DASH score at 6 month was 1.45 (0.83-2.5). The self-evaluated aesthetic results showed twelve patients (85.7%) were very satisfied, and no patient was completely unsatisfied. In Hirase zone IIA traumatic fingertip amputation where replantation is difficult, our modified technique of composite grafting with pulp adipofascial advancement flap provided an alternative choice with high successful rate, acceptable functional and aesthetic outcomes. © 2016 Wiley Periodicals, Inc.

2010-12-01

In this thesis the term eye amputation (EA) covers the removing of an eye by: evisceration, enucleation and exenteration. Amputation of an eye is most frequently the end-stage in a complicated disease, or the primary treatment in trauma and neoplasm. In 2010 the literature is extensive due to knowledge about types of surgery, implants and surgical technique. However, not much is known about the time past surgery. To identify the number of EA, the causative diagnosis and the indication for surgical removal of the eye, the chosen surgical technique and to evaluate a possible change in surgical technique in Denmark from 1996 until 2003 (paper I); To describe the phantom eye syndrome and its prevalence of visual hallucinations, phantom pain and phantom sensations (paper II); To characterise the quality of phantom eye pain, including its intensity and frequency among EA patients. We attempted to identify patients with increased risk of developing pain after EA and investigated if preoperative pain is a risk factor for a later development of phantom pain (paper III); In addition we wanted to investigate the health related quality of life, perceived stress, self rated health, job separation due to illness or disability and socio-economic position of the EA in comparison with the general Danish population (paper IV). Records on 431 EA patients, clinical ophthalmological examination and an interview study of 173 EA patients and a questionnaire answered by 120 EA patients. The most frequent indications for EA in Denmark were painful blind eye (37%) and neoplasm (34%). During the study period 1996-2003, the annual number of eye amputations was stable, but an increase in bulbar eviscerations was noticed. Orbital implants were used with an increasing tendency until 2003. The Phantom eye syndrome is frequent among EA patients. Visual hallucinations were described by 42% of the patients. The content were mainly elementary visual hallucinations, with white or colored light as a

Full Text Available Background. Hemipelvectomy amputation is a surgical procedure in which lower limb and a portion of pelvic are removed. There are a few studies in the literature regarding the performance of subjects with hip disarticulation during walking. However, there is no study on gait analysis of hemipelvectomy subject. Therefore, the aim of this paper was to evaluate the gait and stability of subject with hemipelvectomy amputation. Case Description and Methods. A subject with hemipelvectomy amputation at right side was involved in this study. He used a Canadian prosthesis with single axis ankle joint, 3R21 knee joint, and 7E7 hip joint for more than 10 years. The kinetic and kinematic parameters were collected by a motion analysis system and a Kistler force platform. Findings and Outcomes. There was a significant difference between knee, hip, and ankle range of motions and their moments in the sound and prosthesis sides. In the other side, the stability of the subject in the anteroposterior direction seems to be better than that in the mediolateral direction. Conclusions. There was a significant asymmetry between the kinetic and kinematic performance of the sound and prosthesis sides, which may be due to lack of muscular power and alignment of prosthesis components.

Injuries to the fingertips are among the most common injuries to the hand and result in approximately 4.8 million emergency department visits per year. Most injuries are lacerations or crushes; amputations represent a small but complex spectrum of injury. Treatments available cover a broad range of techniques with no single recommended reference standard for treatment. Although there is no consensus on how these injuries should be treated, the goals of treatment should include minimization of pain, optimization of healing time, preservation of sensibility and length, prevention of painful neuromas, avoidance or limiting of nail deformity, minimization of time lost from work, and provision of an acceptable cosmetic appearance. In this review we present a variety of options in caring for these injuries to help achieve these goals, and the available data that support the various treatment plans.

Bruna Maria Bueno Barbosa

Full Text Available ABSTRACT: Objective: It was to identify trends of traumatic and non-traumatic causes of lower limb amputations, as well as the role played by population aging, traffic violence increase, public health policy of diabetes control program and drivers anti-alcohol laws on these amputations. Method: Hospitalization data recorded in the discharge forms of 32 hospitals located in the region of Ribeirão Preto, Brazil, from 1985 to 2008 were analyzed. Result: A total of 3,274 lower-limb amputations were analyzed, of which 95.2% were related to non-traumatic causes, mainly infectious and ischemic complications of diabetes mellitus. Cancer (2.8% and congenital (1.3% causes were included in this group. Only 4.8% were related to traumatic causes. Traumatic amputation average rate was 1.5 amputations in 100,000 habitants with a slight tendency of increase in the last 5 years. Non-traumatic causes showed an average rate of 30.0 amputations for 100,000 habitants and remained relatively constant during the whole period. Non-traumatic were much more predominant in patients older than 60 years and traumatic amputations occurred more frequently in patients younger than 39 years. Conclusion: The overall rates of amputation and the rates of traumatic and non-traumatic amputations remained nearly constant during the study period. The impact of diabetes control policies and the introduction of traffic safety laws could not be identified on the amputation rates.

Xenomelia is a rare condition characterized by the persistent desire for the amputation of physically healthy limbs. Prior studies highlighted the importance of superior and inferior parietal lobuli (SPL/IPL) and other sensorimotor regions as key brain structures associated with xenomelia. We expected activity differences in these areas in response to pictures showing the desired body state, i.e. that of an amputee in xenomelia. Functional magnetic resonance images were acquired in 12 xenomelia individuals and 11 controls while they viewed pictures of their own real and virtually amputated body. Pictures were rated on several dimensions. Multivariate statistics using machine learning was performed on imaging data. Brain activity when viewing pictures of one's own virtually amputated body predicted group membership accurately with a balanced accuracy of 82.58% (p = 0.002), sensitivity of 83.33% (p = 0.018), specificity of 81.82% (p = 0.015) and an area under the ROC curve of 0.77. Among the highest predictive brain regions were bilateral SPL, IPL, and caudate nucleus, other limb representing areas, but also occipital regions. Pleasantness and attractiveness ratings were higher for amputated bodies in xenomelia. Findings show that neuronal processing in response to pictures of one's own desired body state is different in xenomelia compared with controls and might represent a neuronal substrate of the xenomelia complaints that become behaviourally relevant, at least when rating the pleasantness and attractiveness of one's own body. Our findings converge with structural peculiarities reported in xenomelia and partially overlap in task and results with that of anorexia and transgender research. Copyright © 2017 Elsevier Ltd.

Full Text Available Abstract Background Recurrent dislocation of the patella in patients with below knee amputation is a known entity. Abnormally high-riding patella (patella alta and medial patellofemoral ligament insufficiency in these patients predisposes them to patellar instability. The established treatment of this problem is surgical realignment. Case presentation A 25 year old male patient with bilateral below knee amputation presented with bilateral recurrent dislocation of the patella while walking on knees on uneven ground. Clinical and radiographic studies showed patella alta. A simple shoe modification was used to treat this patient. Conclusions A simple shoe modification can be used to treat such a condition which is otherwise treated surgically.

Stepwise surgical approach to diabetic partial foot amputations with autogenous split thickness skin grafting

Directory of Open Access Journals (Sweden)

Crystal L. Ramanujam

2016-06-01

Full Text Available In the surgical treatment of severe diabetic foot infections, substantial soft tissue loss often accompanies partial foot amputations. These sizeable soft tissue defects require extensive care with the goal of expedited closure to inhibit further infection and to provide resilient surfaces capable of withstanding long-term ambulation. Definitive wound closure management in the diabetic population is dependent on multiple factors and can have a major impact on the risk of future diabetic foot complications. In this article, the authors provide an overview of autogenous skin grafting, including anatomical considerations, clinical conditions, surgical approach, and adjunctive treatments, for diabetic partial foot amputations.

Symmetrical kinematics does not imply symmetrical kinetics in people with transtibial amputation using cycling model.

Childers, W Lee; Kogler, Géza F

People with amputation move asymmetrically with regard to kinematics (joint angles) and kinetics (joint forces and moments). Clinicians have traditionally sought to minimize kinematic asymmetries, assuming kinetic asymmetries would also be minimized. A cycling model evaluated locomotor asymmetries. Eight individuals with unilateral transtibial amputation pedaled with 172 mm-length crank arms on both sides (control condition) and with the crank arm length shortened to 162 mm on the amputated side (CRANK condition). Pedaling kinetics and limb kinematics were recorded. Joint kinetics, joint angles (mean and range of motion [ROM]), and pedaling asymmetries were calculated from force pedals and with a motion capture system. A one-way analysis of variance with tukey post hoc compared kinetics and kinematics across limbs. Statistical significance was set to p Pedaling asymmetries did not differ and were 23.0% +/= 9.8% and 23.2% +/= 12% for the control and CRANK conditions, respectively. Our results suggest that minimizing kinematic asymmetries does not relate to kinetic asymmetries as clinically assumed. We propose that future research should concentrate on defining acceptable asymmetry.

Loss of long-term depression in the insular cortex after tail amputation in adult mice.

Science.gov (United States)

Liu, Ming-Gang; Zhuo, Min

2014-01-08

The insular cortex (IC) is an important forebrain structure involved in pain perception and taste memory formation. Using a 64-channel multi-electrode array system, we recently identified and characterized two major forms of synaptic plasticity in the adult mouse IC: long-term potentiation (LTP) and long-term depression (LTD). In this study, we investigate injury-related metaplastic changes in insular synaptic plasticity after distal tail amputation. We found that tail amputation in adult mice produced a selective loss of low frequency stimulation-induced LTD in the IC, without affecting (RS)-3,5-dihydroxyphenylglycine (DHPG)-evoked LTD. The impaired insular LTD could be pharmacologically rescued by priming the IC slices with a lower dose of DHPG application, a form of metaplasticity which involves activation of protein kinase C but not protein kinase A or calcium/calmodulin-dependent protein kinase II. These findings provide important insights into the synaptic mechanisms of cortical changes after peripheral amputation and suggest that restoration of insular LTD may represent a novel therapeutic strategy against the synaptic dysfunctions underlying the pathophysiology of phantom pain.

To investigate the predictive value of both patients' motivation and effort in their management of Type 2 diabetes and their life circumstances for the development of foot ulcers and amputations. This study was based on the Diabetes Care in General Practice study and Danish population and health registers. The associations between patient motivation, effort and life circumstances and foot ulcer prevalence 6 years after diabetes diagnosis and the incidence of amputation in the following 13 years were analysed using odds ratios from logistic regression and hazard ratios from Cox regression models, respectively. Foot ulcer prevalence 6 years after diabetes diagnosis was 2.93% (95% CI 1.86-4.00) among 956 patients. General practitioners' indication of 'poor' vs 'very good' patient motivation for diabetes management was associated with higher foot ulcer prevalence (odds ratio 6.11, 95% CI 1.22-30.61). The same trend was seen for 'poor' vs 'good' influence of the patient's own effort in diabetes treatment (odds ratio 7.06, 95% CI 2.65-18.84). Of 1058 patients examined at 6-year follow-up, 45 experienced amputation during the following 13 years. 'Poor' vs 'good' influence of the patients' own effort was associated with amputation (hazard ratio 7.12, 95% CI 3.40-14.92). When general practitioners assessed the influence of patients' life circumstances as 'poor' vs 'good', the amputation incidence increased (hazard ratio 2.97, 95% CI 1.22-7.24). 'Poor' vs 'very good' patient motivation was also associated with a higher amputation incidence (hazard ratio 7.57, 95% CI 2.43-23.57), although not in fully adjusted models. General practitioners' existing knowledge of patients' life circumstances, motivation and effort in diabetes management should be included in treatment strategies to prevent foot complications. © 2014 The Authors.

Patients with transfemoral amputation (TFA) often experience problems related to the use of socket-suspended prostheses. The clinical development of osseointegrated percutaneous prostheses for patients with a TFA started in 1990, based on the long-term successful results of osseointegrated dental implants. Between 1999 and 2007, 51 patients with 55 TFAs were consecutively enrolled in a prospective, single-centre non-randomised study and followed for two years. The indication for amputation was trauma in 33 patients (65%) and tumour in 12 (24%). A two-stage surgical procedure was used to introduce a percutaneous implant to which an external amputation prosthesis was attached. The assessment of outcome included the use of two self-report questionnaires, the Questionnaire for Persons with a Transfemoral Amputation (Q-TFA) and the Short-Form (SF)-36. The cumulative survival at two years' follow-up was 92%. The Q-TFA showed improved prosthetic use, mobility, global situation and fewer problems (all p reported following treatment with osseointegrated percutaneous prostheses.

Full Text Available The proximal tibia (pT is a common site for bone tumors. Improvements in imaging, chemotherapy and surgical technique made limb salvage surgery the treatment of choice. Yet, reconstructions of the pT have been associated with less favorable outcome compared to other parts of the extremities. The aim of this study was to evaluate the outcome of patients with a modular endoprosthetic reconstruction of the pT.Eighty-one consecutive patients with an average age of 29 years underwent endoprosthetic reconstruction of the pT. Postoperative complications were categorized according to the ISOLS classification, and revision-free survival until first complication (any Type 1-5, soft tissue failure (Type 1, aseptic loosening (Type 2, structural failure (Type 3, infection (Type 4, and local tumor progression (Type 5 was estimated by using a Fine-Gray model for competing risk analyses for univariate and multivariable regression with Firth's bias correction.A total of 45 patients (56% had at least one complication. Cumulative incidence for complication Types 1 to 5 at 5 years with death and amputation as competing events revealed a risk of 41% for the first complication, 14% for Type 1, 16% for Type 2, 11% for Type 3, 17% for Type 4, and 1% for Type 5.Despite inclusion of amputation and death as strong competing events, pT replacements are still associated with a high risk of postoperative failures. The results suggest that infection and soft tissue failures (Type 1 and 5 seem to depend from each other. Sufficient soft tissue reconstruction and closure allow better function and reduce the risk of infection as the most prominent complication. The use of a rotating hinge design has significantly reduced structural failures over time.

Armstrong, David G; Lavery, Lawrence A; Boulton, Andrew J M

2007-03-01

Randomised clinical trials (RCTs) to evaluate diabetic foot wound therapies have systematically eliminated large acute wounds from evaluation, focusing only on smaller chronic wounds. The purpose of this study was to evaluate the proportion and rate of wound healing in acute and chronic wounds after partial foot amputation in individuals with diabetes treated with negative pressure wound therapy (NPWT) delivered by the vacuum-assisted closure (VAC) device or with standard wound therapy (SWT). This study constitutes a secondary analysis of patients enrolled in a 16-week RCT of NPWT: 162 open foot amputation wounds (mean wound size = 20.7 cm(2)) were included. Acute wounds were defined as the wounds less than 30 days after amputation, whereas chronic wounds as the wounds greater than 30 days. Inclusion criteria consisted of individuals older than 18 years, presence of a diabetic foot amputation wound up to the transmetatarsal level and adequate perfusion. Wound size and healing were confirmed by independent, blinded wound evaluators. Analyses were done on an intent-to-treat basis. There was a significantly higher proportion of acute wounds (SWT = 59; NPWT = 63) than chronic wounds (SWT = 26; NPWT = 14), evaluated in this clinical trial (P = 0.001). There was no significant difference in the proportion of acute and chronic wounds achieving complete wound closure in either treatment group. Despite this finding, the Kaplan-Meier curves demonstrated statistically significantly faster healing in the NPWT group in both acute (P = 0.030) and chronic wounds (P = 0.033). Among the patients treated with NPWT via the VAC, there was not a significant difference in healing as a function of chronicity. In both the acute and the chronic wound groups, results for patients treated with NPWT were superior to those for the patients treated with SWT. These results appear to indicate that wound duration should not deter the clinician from using this modality to treat complex wounds.

To describe indicators of job dissatisfaction among amputee employees and to compare job satisfaction and health experience of working amputee employees with that of control subjects. A cross-sectional study, mailed questionnaire. Patients were recruited by the orthopedic workshops of the Netherlands. One hundred forty-four patients who had an acquired unilateral major amputation of the lower limb at least 2 years before, were aged 18 to 60 years (mean age, 43y), and were living and working in the Netherlands. One hundred forty-four control subjects matched for age, gender, and type of job. Not applicable. Statistical analysis of responses to a questionnaire regarding patient characteristics and amputation-related factors, amputee patients' opinions about their work and the social atmosphere at work, and their general health (RAND 36-Item Health Survey [RAND-36]). People with an amputation had greater job satisfaction (70%) than did the able-bodied control group (54%). The wish for (better) modifications in the workplace and the presence of comorbidity were significantly related to job dissatisfaction in people with limb loss. Amputee employees were less often hindered by the failures of others and by fluctuations in temperature. People with limb loss showed a worse physical health experience than controls on the RAND-36. The vocational satisfaction of people with limb loss may be improved by better workplace modifications, depending on the functional capabilities of the person and the functional demands of the job; improvement may also be achieved by vocational rehabilitation programs, especially for those with an amputation in combination with other morbidity. Despite experiencing more health problems, the amputee group expressed greater job satisfaction than the able-bodied group, reflecting a great appreciation of job reintegration by people with a lower-limb amputation.

Energy storing feet are unable to reduce the energy required for normal locomotion among people with transtibial amputation. Crossover feet, which incorporate aspects of energy storing and running specific feet, are designed to maximize energy return while providing stability for everyday activities. Do crossover prosthetic feet reduce the energy expenditure of walking across a range of speeds, when compared with energy storing feet among people with transtibial amputation due to non-dysvascular causes? A randomized within-subject study was conducted with a volunteer sample of twenty-seven adults with unilateral transtibial amputation due to non-dysvascular causes. Participants were fit with two prostheses. One had an energy storing foot (Össur Variflex) and the other a crossover foot (Össur Cheetah Xplore). Other components, including sockets, suspension, and interface were standardized. Energy expenditure was measured with a portable respirometer (Cosmed K4b2) while participants walked on a treadmill at self-selected slow, comfortable, and fast speeds with each prosthesis. Gross oxygen consumption rates (VO 2  ml/min) were compared between foot conditions. Energy storing feet were used as the baseline condition because they are used by most people with a lower limb prosthesis. Analyses were performed to identify people who may benefit from transition to crossover feet. On average, participants had lower oxygen consumption in the crossover foot condition compared to the energy storing foot condition at each self-selected walking speed, but this difference was not statistically significant. Participants with farther six-minute walk test distances, higher daily step counts, and higher Medicare Functional Classification Levels at baseline were more likely to use less energy in the crossover foot. Crossover feet may be most beneficial for people with higher activity levels and physical fitness. Further research is needed to examine the effect of crossover feet on

The experience of post-amputation pain such as phantom limb pain (PLP) and residual limb pain (RLP), is a common consequence of limb amputation, and its presence has negative effects on a person’s well-being. The continuity hypothesis of dreams suggests that the presence of such aversive experiences in the waking state should be reflected in dream content, with the recalled body representation reflecting a cognitive proxy of negative impact. In the present study, we epidemiologically assessed the presence of post-amputation pain and other amputation-related information as well as recalled body representation in dreams in a sample of 3,234 unilateral limb amputees. Data on the site and time of amputation, residual limb length, prosthesis use, lifetime prevalence of mental disorders, presence of post-amputation pain, and presence of non-painful phantom phenomena were included in logistic regression analyses using recalled body representation in dreams (impaired, intact, no memory) as dependent variable. The effects of age, sex, and frequency of dream recall were controlled for. About 22% of the subjects indicated that they were not able to remember their body representation in dreams, another 24% of the amputees recalled themselves as always intact, and only a minority of less than 3% recalled themselves as always impaired. Almost 35% of the amputees dreamed of themselves in a mixed fashion. We found that lower-limb amputation as well as the presence of PLP and RLP was positively associated with the recall of an impaired body representation in dreams. The presence of non-painful phantom phenomena, however, had no influence. These results complement previous findings and indicate complex interactions of physical body appearance and mental body representation, probably modulated by distress in the waking state. The findings are discussed against the background of alterations in cognitive processes after amputation and hypotheses suggesting an innate body model. PMID

The improvement of gait and mobility are major rehabilitation goals following lower extremity amputations. However, when living in the community many daily activities require the multitasking of motor and cognitive tasks. The dual-task paradigm can be used to evaluate the concurrent performance of mobility and cognitive tasks. The purpose of this study was to evaluate the effects of dual-task gait testing in older adults with trans-tibial amputations. Twenty-four people (15 men, mean age ± SD, 62.72 ± 8.59) with trans-tibial amputation walked on an electronic walkway at i) self-selected comfortable pace and ii) self-selected comfortable pace while counting backwards by threes from a number randomly selected between 100 and 150. Cognitive performance, in the form of corrected response rate, was also evaluated as a single-task. The dual-task testing produced poorer performance in velocity (single-task = 58.15 ± 23.16 cm/s, dual-task = 50.92 ± 21.16 cm/s, p = 0.008), cadence (single-task = 76.65 ± 15.84 steps/min, dual-task = 67.85 ± 15.76 steps/min, p = 0.002) and stride time (single-task = 1094 ± 458.28 ms, dual-task = 1241.44 ± 513.73 ms, p = 0.005). Step length, stance time and single limb support time symmetry were also affected, such that less time was spent on the amputated limb during the dual-task testing. Dual-task testing demonstrated interference resulting in a poor performance in both gait and cognitive performance in trans-tibial amputees. Further research is suggested to evaluate the change in cognition-mobility effects over time and the relationship of this value to future adverse events such as falls and successful outcomes such as community ambulation and reintegration.

Knowledge about the organization and factors of importance to rehabilitation of veterans with lower limb amputation is sparse. The aim of this study was, therefore, to improve understanding of the influences of "military identity" on the organization of rehabilitation services and to investigate those factors influential in achieving successful rehabilitation, including interprofessional collaboration between different sectors involved in the rehabilitation of veterans with lower limb amputations. We used a qualitative exploratory design, triangulating interviews and participant observation. Data were generated using in-depth semi-structured interviews (n = 6) exploring in-hospital and post-hospital rehabilitation in Danish veterans after unilateral lower limb amputation due to trauma. We conducted four sessions of participant observation, during weekly post-hospitalization rehabilitation and included field notes in the dataset. Two main themes emerged: "experiencing different identities" and "experiencing discontinuity in rehabilitation." The first theme illustrated how veterans actively shift between the identities of disabled person, wounded veteran and athlete according to the context. The second theme illustrated the frustration of negotiating military versus civilian mindsets during rehabilitation and lack of coordination between the public healthcare system, municipal services and the military. Veterans live with shifting identities after returning to civilian life, increasing their awareness of the transition from active service to a new life as a civilian. During rehabilitation, it is important to acknowledge the disparities between the military and civilian mindsets and to integrate the different sets of values, such as structure versus autonomy. IMPLICATIONS FOR REHABILITATION Recommendations for the improvement of rehabilitation of amputated veterans include: Rehabilitation professionals working with veterans should focus on abilities instead of

Full Text Available The repair of peripheral nerve injury after complete amputation is difficult, and even with anastomosis, the rapid recovery of nerve function remains challenging. Curcumin, extracted from plants of the genus Curcuma, has been shown to have anti-oxidant and anti-inflammatory properties and to improve sciatic nerve crush injury in rats. Here, we determined whether curcumin had neuroprotective effects following complete peripheral nerve amputation injury. BALB/c mice underwent complete sciatic nerve amputation, followed by an immediate epineurium anastomosis. Mice were intragastrically administered curcumin at doses of 40 (high, 20 (moderate, and 10 mg/kg/d (low for 1 week. We found that myelin in the mice of the high- and moderate-dose curcumin groups appeared with regular shape, uniform thickness, clear boundary, and little hyperplasia surrounding the myelin. High and moderate doses of curcumin markedly improved both action potential amplitude of the sciatic nerves and the conduction velocity of the corresponding motor neurons, and upregulated mRNA and protein expression of S100, a marker for Schwann cell proliferation, in L4–6 spinal cord segments. These results suggest that curcumin is effective in promoting the repair of complete sciatic nerve amputation injury and that the underlying mechanism may be associated with upregulation of S100 expression.

This is the first update of a Cochrane review published in Issue 5, 2010 on transcutaneous electrical nerve stimulation (TENS) for phantom pain and stump pain following amputation in adults. Pain may present in a body part that has been amputated (phantom pain) or at the site of amputation (stump pain), or both. Phantom pain and stump pain are complex and multidimensional and the underlying pathophysiology remains unclear. The condition remains a severe burden for those who are affected by it. The mainstay treatments are predominately pharmacological, with increasing acknowledgement of the need for non-drug interventions. TENS has been recommended as a treatment option but there has been no systematic review of available evidence. Hence, the effectiveness of TENS for phantom pain and stump pain is currently unknown. To assess the analgesic effectiveness of TENS for the treatment of phantom pain and stump pain following amputation in adults. For the original version of the review we searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, PsycINFO, AMED, CINAHL, PEDRO and SPORTDiscus (February 2010). For this update, we searched the same databases for relevant randomised controlled trials (RCTs) from 2010 to 25 March 2015. We only included RCTs investigating the use of TENS for the management of phantom pain and stump pain following an amputation in adults. Two review authors independently assessed trial quality and extracted data. We planned that where available and appropriate, data from outcome measures were to be pooled and presented as an overall estimate of the effectiveness of TENS. In the original review there were no RCTs that examined the effectiveness of TENS for the treatment of phantom pain and stump pain in adults. For this update, we did not identify any additional RCTs for inclusion. There were no RCTs to judge the effectiveness of TENS for the management of phantom pain and stump pain.

Any defect in extremities of the body can affect different life aspects. The purpose of this study was to investigate the effect of Roy's adaptation model-guided education on promoting the adaptation of veterans with lower extremities amputation. In a randomized clinical trial, 60 veterans with lower extremities amputation referring to Kowsar Orthotics and Prosthetics Center of veterans clinic in Tehran, Iran, were recruited with convenience method and were randomly assigned to intervention and control groups during 2013 - 2014. For data collection, Roy's adaptation model questionnaire was used. After completing the questionnaires in both groups, maladaptive behaviors were determined in the intervention group and an education program based on Roy's adaptation model was implemented. After two months, both groups completed the questionnaires again. Data was analyzed with SPSS software. Independent t-test showed statistically significant differences between the two groups in the post-test stage in terms of the total score of adaptation (P = 0.001) as well as physiologic (P = 0.0001) and role function modes (P = 0.004). The total score of adaptation (139.43 ± 5.45 to 127.54 ± 14.55, P = 0.006) as well as the scores of physiologic (60.26 ± 5.45 to 53.73 ± 7.79, P = 0.001) and role function (20.30 ± 2.42 to 18.13 ± 3.18, P = 0.01) modes in the intervention group significantly increased, whereas the scores of self-concept (42.10 ± 4.71 to 39.40 ± 5.67, P = 0.21) and interdependence (16.76 ± 2.22 to 16.30 ± 2.57, P = 0.44) modes in the two stages did not have a significant difference. Findings of this research indicated that the Roy's adaptation model-guided education promoted the adaptation level of physiologic and role function modes in veterans with lower extremities amputation. However, this intervention could not promote adaptation in self-concept and interdependence modes. More intervention is advised based on Roy's adaptation model for improving the

Disappearance of "phantom limb" and amputated arm usage during dreaming in REM sleep behaviour disorder.

Science.gov (United States)

Vetrugno, Roberto; Arnulf, Isabelle; Montagna, Pasquale

2009-01-01

Limb amputation is followed, in approximately 90% of patients, by "phantom limb" sensations during wakefulness. When amputated patients dream, however, the phantom limb may be present all the time, part of the time, intermittently or not at all. Such dreaming experiences in amputees have usually been obtained only retrospectively in the morning and, moreover, dreaming is normally associated with muscular atonia so the motor counterpart of the phantom limb experience cannot be observed directly. REM sleep behaviour disorder (RBD), in which muscle atonia is absent during REM sleep and patients act out their dreams, allows a more direct analysis of the "phantom limb" phenomena and their modifications during sleep.

Full Text Available Abstract Background Autologous bone marrow-derived stem cells have been ascribed an important therapeutic role in No-Option Critical limb Ischemia (NO-CLI. One primary endpoint for evaluating NO-CLI therapy is major amputation (AMP, which is usually combined with mortality for AMP-free survival (AFS. Only a trial which is double blinded can eliminate physician and patient bias as to the timing and reason for AMP. We examined factors influencing AMP in a prospective double-blinded pilot RCT (2:1 therapy to control of 48 patients treated with site of service obtained bone marrow cells (BMAC as well as a systematic review of the literature. Methods Cells were injected intramuscularly in the CLI limbs as either BMAC or placebo (peripheral blood. Six month AMP rates were compared between the two arms. Both patient and treating team were blinded of the assignment in follow-up examinations. A search of the literature identified 9 NO-CLI trials, the control arms of which were used to determine 6 month AMP rates and the influence of tissue loss. Results Fifteen amputations occurred during the 6 month period, 86.7% of these during the first 4 months. One amputation occurred in a Rutherford 4 patient. The difference in amputation rate between patients with rest pain (5.6% and those with tissue loss (46.7%, irrespective of treatment group, was significant (p = 0.0029. In patients with tissue loss, treatment with BMAC demonstrated a lower amputation rate than placebo (39.1% vs. 71.4%, p = 0.1337. The Kaplan-Meier time to amputation was longer in the BMAC group than in the placebo group (p = 0.067. Projecting these results to a pivotal trial, a bootstrap simulation model showed significant difference in AFS between BMAC and placebo with a power of 95% for a sample size of 210 patients. Meta-analysis of the literature confirmed a difference in amputation rate between patients with tissue loss and rest pain. Conclusions BMAC shows promise in improving AMP

Running-specific prostheses enable athletes with lower limb amputations to run by emulating the spring-like function of biological legs. Current prosthetic stiffness and height recommendations aim to mitigate kinematic asymmetries for athletes with unilateral transtibial amputations. However, it is unclear how different prosthetic configurations influence the biomechanics and metabolic cost of running. Consequently, we investigated how prosthetic model, stiffness, and height affect the biomechanics and metabolic cost of running. Ten athletes with unilateral transtibial amputations each performed 15 running trials at 2.5 or 3.0 m/s while we measured ground reaction forces and metabolic rates. Athletes ran using three different prosthetic models with five different stiffness category and height combinations per model. Use of an Ottobock 1E90 Sprinter prosthesis reduced metabolic cost by 4.3 and 3.4% compared with use of Freedom Innovations Catapult [fixed effect (β) = -0.177; P Run (β = -0.139; P = 0.002) prostheses, respectively. Neither prosthetic stiffness ( P ≥ 0.180) nor height ( P = 0.062) affected the metabolic cost of running. The metabolic cost of running was related to lower peak (β = 0.649; P = 0.001) and stance average (β = 0.772; P = 0.018) vertical ground reaction forces, prolonged ground contact times (β = -4.349; P = 0.012), and decreased leg stiffness (β = 0.071; P running. Instead, an optimal prosthetic model, which improves overall biomechanics, minimizes the metabolic cost of running for athletes with unilateral transtibial amputations. NEW & NOTEWORTHY The metabolic cost of running for athletes with unilateral transtibial amputations depends on prosthetic model and is associated with lower peak and stance average vertical ground reaction forces, longer contact times, and reduced leg stiffness. Metabolic cost is unrelated to prosthetic stiffness, height, and stride kinematic symmetry. Unlike nonamputees who decrease leg stiffness with

The problems of prescribing a prosthesis for a young girl with severe congenital vascular malformation deformity leading to a transtibial amputation. Due to the high risk of recurrent bleeding and limitations regarding full weight bearing of the stump, a normal socket fitting process was not possible. Using a multidisciplinary approach, a prosthesis was designed to enable full weight bearing in a flexed knee position with ischial tuberosity support to prevent full weight bearing on the tibial part of the stump. After training and adjustments to the design, a definitive prosthesis with a free motion mechanical knee joint could be used. During the training with this prosthesis, no skin problems were observed, and at the end of the rehabilitation, the patient had a high level of activities of daily living and sports. The above prosthetic solution with an adjusted socket design proved to be successful in this case. Clinical relevance In a patient with severe congenital vascular malformation deformity leading to a transtibial amputation, fitting of a good prosthesis without full weight bearing of the stump proved to be successful.

Dose-dependent effects of an immune challenge at both ultimate and proximate levels in Drosophila melanogaster.

Science.gov (United States)

Nystrand, M; Dowling, D K

2014-05-01

Immune responses are highly dynamic. The magnitude and efficiency of an immune response to a pathogen can change markedly across individuals, and such changes may be influenced by variance in a range of intrinsic (e.g. age, genotype, sex) and external (e.g. abiotic stress, pathogen identity, strain) factors. Life history theory predicts that up-regulation of the immune system will come at a physiological cost, and studies have confirmed that increased investment in immunity can reduce reproductive output and survival. Furthermore, males and females often have divergent reproductive strategies, and this might drive the evolution of sex-specific life history trade-offs involving immunity, and sexual dimorphism in immune responses per se. Here, we employ an experiment design to elucidate dose-dependent and sex-specific responses to exposure to a nonpathogenic immune elicitor at two scales--the 'ultimate' life history and the underlying 'proximate' immune level in Drosophila melanogaster. We found dose-dependent effects of immune challenges on both male and female components of reproductive success, but not on survival, as well as a response in antimicrobial activity. These results indicate that even in the absence of the direct pathogenic effects that are associated with actual disease, individual life histories respond to a perceived immune challenge--but with the magnitude of this response being contingent on the initial dose of exposure. Furthermore, the results indicate that immune responses at the ultimate life history level may indeed reflect underlying processes that occur at the proximate level. © 2014 The Authors.

This case study highlights the use of vacuum-assisted closure (VAC) in a diabetic man following a partial transverse amputation of his foot. In this situation infection-free healing is imperative in order to salvage the limb and prevent further trauma. VAC therapy facilitates rapid granulation of wounds and reduces bacterial colonization rates. This method was adopted as a suitable therapy for treatment of a patient who suffered from a complex wound at high-risk of reinfection.

Structured health care for subjects with diabetic foot ulcers results in a reduction of major amputation rates

Science.gov (United States)

2013-01-01

Objective We tested the effects of structured health care for the diabetic foot in one region in Germany aiming to reduce the number of major amputations. Research design and methods In a prospective study we investigated patients with diabetic foot in a structured system of outpatient, in-patient and rehabilitative treatment. Subjects were recruited between January 1st, 2000 and December 31, 2007. All participants underwent a two-year follow-up. The modified University of Texas Wound Classification System (UT) was the basis for documentation and data analysis. We evaluated numbers of major amputations, rates of ulcer healing and mortality. In order to compare the effect of the structured health care program with usual care in patients with diabetic foot we evaluated the same parameters at another regional hospital without interdisciplinary care of diabetic foot (controls). Results 684 patients with diabetic foot and 508 controls were investigated. At discharge from hospital 28.3% (structured health care program, SHC) vs. 23.0% (controls) of all ulcers had healed completely. 51.5% (SHC) vs. 49.8% (controls) were in UT grade 1. Major amputations were performed in 32 subjects of the structured health care program group (4.7%) vs. 110 (21.7%) in controls (p<0.0001). Mortality during hospitalization was 2.5% (SHC) vs. 9.4% in controls (p<0.001). Conclusions With the structured health care program we achieved a significant reduction of major amputation rates by more than 75% as compared to standard care. PMID:23497152

Full Text Available Sprinting with a lower-limb amputation over 100 m has taken place in the Paralympic Games for over three decades. The aim of this paper is to statistically evaluate the performances and participation levels of such athletes during this period. The level of performance improvement over a 36-year period was proposed to be significantly greater than the able-bodied equivalent. Coupled with this, a major spike in amputee running performance improvement was shown to occur from 1984–1988. This supports previously recorded accounts of a major technological change being made at this time. Finally, whilst the average performance of the medallists has increased consistently over the 36-year history, the overall participation in the event fell significantly after 1988 and did not recover until 2012.

Despite advances in the treatment of peripheral arterial disease, a significant number of patients ultimately require major amputations. Traditionally, postoperative management of a below-knee amputation involves soft compressive dressings to allow for complete stump healing before initial prosthesis fitting. This technique is associated with a prolonged period of limited mobility, placing patients at risk for deconditioning or fall with a risk of injury to the stump. In contrast, immediate postoperative prosthesis (IPOP) placement allows patients to begin ambulation and rehabilitation on postoperative day 1, which may be of significant physiologic and psychological benefit. The purpose of this study is to compare the outcomes of patients undergoing IPOP placement to those of a historical control group managed with traditional soft compressive dressing placement. Medical records of all consecutive below-knee amputation patients who underwent IPOP (IPOP group; 37 patients, 2007-2010) and all patients who underwent traditional soft compressive dressing placement and were IPOP candidates (non-IPOP group; 35 patients, 2006-2007) were retrospectively reviewed. Patient comorbidities and preoperative ambulation status were compared between the IPOP and the non-IPOP groups. Primary outcomes evaluated included perioperative systemic complications, wound complications, need for surgical revision, and the time until placement of a definitive prosthesis. Data were analyzed using the chi-squared and Student's t-test. Preoperative comorbidities and patient characteristics of the 2 groups were similar, although the IPOP group was younger (61.5 vs. 69.0 years; P=0.01). Immediate perioperative systemic complication rates were not significantly different between the 2 groups (IPOP 29.7% vs. non-IPOP 31.4%; P=0.876). Postoperative wound complication rates were as follows: wound infection (IPOP 18.9% vs. non-IPOP 25.0%; P=0.555), wound dehiscence (IPOP 29.7% vs. non-IPOP 25.0%; P=0

Full Text Available BACKGROUND Removal of a part of a limb through one or more bones termed amputation is done for various causes. Properly performed amputation is a reconstructive procedure. Effective postoperative rehabilitation reduces disability and helps in proper shaping of the residual limb leading to final prosthetic fitment. The aim of the study is to compare effect of rigid dressing and Immediate Postoperative Prosthesis (IPOP using a simple and cheap pylon developed by the first author with soft dressing in respect of stump maturation and function in lower limb amputees. MATERIALS AND METHODS Fifty one patients with lower limb amputations were included in the study and randomised into two groups. Twenty four patients completed follow-up in the study group of rigid dressing with early postoperative prosthetic fitting while twenty patients completed with soft dressing. Stump maturation as measured by girth and volumetric assessment and complications of residual pain and phantom pain were compared at six weeks and twelve weeks with baseline data. Statistical Analysis- Done with SPSS for Windows version 17. Independent-T test was used for comparison of continuous variables and Chi-square and Fischer exact test was used for comparison of dichotomous responses. Settings and Design- The study was done in a multispecialty teaching hospital of a metro city. It was a well-structured comparative study done after addressing all safety and ethical issues. RESULTS Stump maturation was significantly better and the stump complications reduced in the study group. CONCLUSION Rigid dressing with IPOP has proven to be significantly superior to soft dressing in terms of maturation of stump and residual complications in lower limb amputations.

Inspired by the springlike action of biological legs, running-specific prostheses are designed to enable athletes with lower-limb amputations to run. However, manufacturer's recommendations for prosthetic stiffness and height may not optimize running performance. Therefore, we investigated the effects of using different prosthetic configurations on the metabolic cost and biomechanics of running. Five athletes with bilateral transtibial amputations each performed 15 trials on a force-measuring treadmill at 2.5 or 3.0 m/s. Athletes ran using each of 3 different prosthetic models (Freedom Innovations Catapult FX6, Össur Flex-Run, and Ottobock 1E90 Sprinter) with 5 combinations of stiffness categories (manufacturer's recommended and ± 1) and heights (International Paralympic Committee's maximum competition height and ± 2 cm) while we measured metabolic rates and ground reaction forces. Overall, prosthetic stiffness [fixed effect (β) = 0.036; P = 0.008] but not height ( P ≥ 0.089) affected the net metabolic cost of transport; less stiff prostheses reduced metabolic cost. While controlling for prosthetic stiffness (in kilonewtons per meter), using the Flex-Run (β = -0.139; P = 0.044) and 1E90 Sprinter prostheses (β = -0.176; P = 0.009) reduced net metabolic costs by 4.3-4.9% compared with using the Catapult prostheses. The metabolic cost of running improved when athletes used prosthetic configurations that decreased peak horizontal braking ground reaction forces (β = 2.786; P = 0.001), stride frequencies (β = 0.911; P < 0.001), and leg stiffness values (β = 0.053; P = 0.009). Remarkably, athletes did not maintain overall leg stiffness across prosthetic stiffness conditions. Rather, the in-series prosthetic stiffness governed overall leg stiffness. The metabolic cost of running in athletes with bilateral transtibial amputations is influenced by prosthetic model and stiffness but not height. NEW & NOTEWORTHY We measured the

Full Text Available Aim: To explore the experiences and perceptions of people with lower limb amputations from the Johannesburg metropolitan area on the impact that their amputations had on their lives and their return to their communities. Methods: Semi-structured audio-taped in-depth interviews were used to collect data on 12 purposively selected participants. Ethical clearance was obtained. A General Inductive Approach was used to generate or discover themes within the data using a process of systematic coding. Results: Emerging from the qualitative data were psychological, social and religious themes. Suicidal thoughts, dependence, poor acceptance, public perception about body image, phantom limb related falls and hopes of obtaining prostheses were reported. Some reported poor social involvement due to mobility problems and employment concerns, while families and friends were found to be supportive. Participants had faith in God. Conclusion: Generally, most participants had come to terms with the amputation and were managing well while some expressed that they were struggling with reintegration to their communities of origin three months postoperatively with both functional and psychosocial challenges.

Hip fracture fixation in a patient with below-knee amputation presents a surgical dilemma: a case report

Full Text Available Abstract Introduction Hip fracture fixation surgery in patients with below-knee amputations poses a challenging problem to the surgeon in terms of obtaining traction for reduction of the fracture. The absence of the foot and part of the leg in these patients makes positioning on the fracture table difficult. We highlight this difficult problem and suggest techniques to overcome it. Case presentation A 73-year-old man with bilateral below-knee amputations presented with a history of fall. Radiographs revealed an inter-trochanteric fracture of the femur. A dynamic hip screw fixation was planned for the fracture but the dilemma was on how to position the patient on the fracture table for the surgery. Special attention was needed in positioning the patient and in surgical fixation of the fracture. Conclusion Hip fracture fixation in patients with below-knee amputations poses a special problem in positioning for fracture reduction and fixation. In this case report, we share our experience and suggest techniques to use when encountering this difficult problem.

Disfigured anatomies and imperfect analogies: body integrity identity disorder and the supposed right to self-demanded amputation of healthy body parts.

Science.gov (United States)

Patrone, D

2009-09-01

Patients with the controversial diagnosis of body integrity identity disorder (BIID) report an emotional discomfort with having a body part (usually a limb) that they feel should not be there. This discomfort is so strong that it interferes with routine functioning and, in a majority of cases, BIID patients are motivated to seek amputation of the limb. Although patient requests to receive the best available treatment are generally respected, BIID demands for amputation, at present, are not. However, what little has been said in the ethics literature on the subject tends to favour doing so in cases of BIID. The general argument is that BIID demands should be respected, first, because of the importance that is already placed on respecting autonomy in medical decision-making contexts and second, because of the potential harm of not providing amputation coupled with the fact that no alternative means of relieving suffering exists. The defence of the right to self-demanded amputation is thus typically supported by the use of analogies with other unproblematical cases in order to show that the denial of BIID patient demands is inconsistent with conventional medical norms and practices. This paper criticises the appropriateness of the particular analogies that are thought to shed light on the allegedly unproblematical nature of BIID demands and argues that a proper understanding of the respect for autonomy in the medical decision-making context prohibits agreeing to BIID demands for amputation.

Several adult reptiles, such as Gekko japonicus, have the ability to precisely re-create a missing tail after amputation. To ascertain the associated acquisition of positional information from blastemal cells and the underlying molecular mechanism of tail regeneration, a candidate molecule CD59 was isolated from gecko. CD59 transcripts displayed a graded expression in the adult gecko spinal cord with the highest level in the anterior segment, with a stable expression along the normal tail. After tail amputation, CD59 transcripts in the spinal cord proximal to the injury sites increased markedly at 1 day and 2 weeks; whereas in the regenerating blastema, strong CD59 positive signals were detected in the blastemal cells anterior to the blastema, with a gradual decrease along the proximodistal (PD) axis. When treated with RA following amputation, CD59 transcripts in the blastema were up-regulated. PD confrontation assays revealed that the proximal blastema engulfed the distal one after in vitro culture, and rabbit-anti human CD59 antibody was able to block this PD engulfment. Overexpression of the CD59 during tail regeneration causes distal blastemal cells to translocate to a more proximal location. Our results suggest that position identity is not restricted to amphibian limb regeneration, but has already been established in tail blastema of reptiles. The CD59, a cell surface molecule, acted as a determinant of proximal–distal cell identity. PMID:21464923

Full Text Available Surgical fixation of hip fractures in patients with below knee amputation is challenging due to the difficulty in obtaining optimal traction for reduction of the fracture. Surgeons may face difficulty in positioning such patients on the traction table due to the absence of the foot and distal lower limb. There are several techniques described to overcome this technical difficulty. In this case report, we present a case of a 64-year old gentleman with bilateral below knee amputation presenting with a comminuted right intertrochanteric fracture. We highlight a simple and effective method of applying skin traction to obtain adequate reduction for hip fracture fixation.

2001-01-01

We studied six pediatric amputees with long below-knee residual limbs, in order to delineate their functional and prosthetic situations, specifically in relation to problems with fitting for dynamic-response prosthetic feet. Three patients had congenital pseudoarthrosis of the tibia secondary to neurofibromatosis, one had fibular hemimelia, one had a traumatic amputation, and one had amputation secondary to burns. Five patients had Syme's amputations, one had a Boyd amputation. Ages at amputation ranged from nine months to five years (average age 3 years 1 month). After amputation, the long residual below-knee limbs allowed fitting with only the lowest-profile prostheses, such as deflection plates. In three patients, the femoral dome to tibial plafond length was greater on the amputated side than on the normal side. To allow room for more dynamic-response (and larger) foot prostheses, two patients have undergone proximal and distal tibial-fibular epiphyseodeses (one at age 5 years 10 months, the other at 3 years 7 months) and one had a proximal tibial-fibular epiphyseodesis at age 7 years 10 months. (All three patients are still skeletally immature.) The families of two other patients are considering epiphyseodeses, and one patient is not a candidate (skeletally mature). Scanogram data indicate that at skeletal maturity the epiphyseodesed patients will have adequate length distal to their residual limbs to fit larger and more dynamic-response prosthetic feet.

Fifteen hundred patients have received deep brain stimulation (DBS) to treat neuropathic pain refractory to pharmacotherapy over the last half-century, but few during the last decade. Deep brain stimulation for neuropathic pain has shown variable outcomes and gained consensus approval in Europe but not the US. This study prospectively evaluated the efficacy at 1 year of DBS for phantom limb pain after amputation, and deafferentation pain after brachial plexus avulsion (BPA), in a single-center case series. Patient-reported outcome measures were collated before and after surgery, using a visual analog scale (VAS) score, 36-Item Short-Form Health Survey (SF-36), Brief Pain Inventory (BPI), and University of Washington Neuropathic Pain Score (UWNPS). Twelve patients were treated over 29 months, receiving contralateral, ventroposterolateral sensory thalamic DBS. Five patients were amputees and 7 had BPAs, all from traumas. A postoperative trial of externalized DBS failed in 1 patient with BPA. Eleven patients proceeded to implantation and gained improvement in pain scores at 12 months. No surgical complications or stimulation side effects were noted. In the amputation group, after 12 months the mean VAS score improved by 90.0% ± 10.0% (p = 0.001), SF-36 by 57.5% ± 97.9% (p = 0.127), UWNPS by 80.4% ± 12.7% (p stimulation demonstrated efficacy at 1 year for chronic neuropathic pain after traumatic amputation and BPA. Clinical trials that retain patients in long-term follow-up are desirable to confirm findings from prospectively assessed case series.

The development of stump and phantom pain after limb amputation in patients with complex regional pain syndrome (CRPS) is very frequent. Stump pain is typically recurred CRPS and the possibilities for effective pharmacological pain relief are often limited. Spinal cord stimulation (SCS) has a well......-documented pain relieving effect in patients with CRPS. This case story summarises the long term effect of SCS in a patient with CRPS after two amputations of the right leg.

Andersen, Romney C; Fleming, Mark; Forsberg, Jonathan A; Gordon, Wade T; Nanos, George P; Charlton, Michael T; Ficke, James R

2012-01-01

The severe Dismounted Complex Blast Injury (DCBI) is characterized by high-energy injuries to the bilateral lower extremities (usually proximal transfemoral amputations) and/or upper extremity (usually involving the non-dominant side), in addition to open pelvic injuries, genitourinary, and abdominal trauma. Initial resuscitation and multidisciplinary surgical management appear to be the keys to survival. Definitive treatment follows general principals of open wound management and includes decontamination through aggressive and frequent debridement, hemorrhage control, viable tissue preservation, and appropriate timing of wound closure. These devastating injuries are associated with paradoxically favorable survival rates, but associated injuries and higher amputation levels lead to more difficult reconstructive challenges.

Prediction of wound healing and major amputation in patients with diabetic foot ulceration is clinically important to stratify risk and target interventions for limb salvage. No consensus exists as to which measure of peripheral artery disease (PAD) can best predict outcomes. To evaluate the prognostic utility of index PAD measures for the prediction of healing and/or major amputation among patients with active diabetic foot ulceration, two reviewers independently screened potential studies for inclusion. Two further reviewers independently extracted study data and performed an assessment of methodological quality using the Quality in Prognostic Studies instrument. Of 9476 citations reviewed, 11 studies reporting on 9 markers of PAD met the inclusion criteria. Annualized healing rates varied from 18% to 61%; corresponding major amputation rates varied from 3% to 19%. Among 10 studies, skin perfusion pressure ≥ 40 mmHg, toe pressure ≥ 30 mmHg (and ≥ 45 mmHg) and transcutaneous pressure of oxygen (TcPO2 ) ≥ 25 mmHg were associated with at least a 25% higher chance of healing. Four studies evaluated PAD measures for predicting major amputation. Ankle pressure diabetic foot ulceration, the measurement of skin perfusion pressures, toe pressures and TcPO2 appear to be more useful in predicting ulcer healing than ankle pressures or the ABI. Conversely, an ankle pressure of < 50 mmHg or an ABI < 0.5 is associated with a significant increase in the incidence of major amputation. Copyright © 2015 John Wiley & Sons, Ltd.

For this study, we compared the physical impairments and functional deficits of individuals with lower-limb amputation (LLA) for those with and without low back pain (LBP). Nineteen participants with LLA were placed into two groups based on visual analog scores of LBP. We assessed functional limitations, iliopsoas length, hamstring length, abdominal strength, back extensor strength, and back extensor endurance. Data analysis included correlations and t-tests. We found significant correlations between pain score and functional limitations, iliopsoas length, and back extensor endurance. We also detected significant differences in functional limitations, iliopsoas length, back extensor strength, and back extensor endurance between those with and without LBP. We saw significant differences in back extensor strength and back extensor endurance between those with transtibial and transfemoral amputations. Differences exist in physical measures of individuals with LLA with and without LBP. Clinicians should consider these impairments in individuals with amputation who experience LBP. Because of the participants' characteristics, these findings may be applicable to veterans with LLA.

Transmetatarsal amputation (TMA) is an effective surgical approach to treat forefoot infection and gangrene in diabetic patients. However, a high rate of complications and failure to heal require reamputation in a large number of cases. We analysed the outcomes of TMA to define the role of revascularization, wound healing and ambulatory status. From January 2008 to January 2013, 218 diabetic patients with foot infection and gangrene, submitted to TMA associated to revascularization were followed until healing, amputation or death. Revascularization was done in 202 (92 %) cases. In 16 (7 %) no revascularization was required. The TMA was closed in 135 (62 %) and left open in 83 (38 %) cases. The reamputation rate was 34 % and major amputation 12.6 % at 1-year follow-up. Patient following ranged 2-30 months with a mean of 15 months. The functional outcomes, living at home and ambulation outdoors, were 60 and 36 % at hospital discharge after TMA, 81 and 77 % at 1-year follow-up. TMA associated to revascularization can provide an effective limb salvage and functional results in diabetic patients with forefoot tissue loss and infection.

Reduced insulin receptor protein levels have been reported in the kidney cortex from diabetic humans and animals. We recently reported that, targeted deletion of insulin receptor (IR) from proximal tubules (PT) resulted in hyperglycemia in non-obese mice. To elucidate the mechanism, we examined human proximal tubule cells (hPTC) and C57BL/6 mice fed with high-fat diet (HFD, 60% fat for 20 weeks). Immunoblotting revealed a significantly lower protein level of IR in HFD compare to normal chow diet (NCD). Furthermore, a blunted rise in p-AKT 308 levels in the kidney cortex of HFD mice was observed in response to acute insulin (0.75 IU/kg body weight, i.p) relative to NCD n = 8/group, P gluconeogenesis. Transcript levels of the gluconeogenic enzyme PEPCK were significantly increased in cAMP/DEXA-stimulated hPTC cells (n = 3, P gluconeogenesis and PEPCK induction was significantly attenuated in IR (siRNA) silenced hPTC (n = 3, P gluconeogenesis. Thus reduced insulin signaling of the proximal tubule may contribute to hyperglycemia in the metabolic syndrome via elevated gluconeogenesis. J. Cell.

Objectives To assess the relationship between proximity to specific sports facilities and participation in the corresponding sports activities for adolescents in Germany. Methods A sample of 1,768 adolescents aged 11–17 years old and living in 161 German communities was examined. Distances to the nearest sports facilities were calculated as an indicator of proximity to sports facilities using Geographic Information Systems (GIS). Participation in specific leisure-time sports activities in sports clubs was assessed using a self-report questionnaire and individual-level socio-demographic variables were derived from a parent questionnaire. Community-level socio-demographics as covariates were selected from the INKAR database, in particular from indicators and maps on land development. Logistic regression analyses were conducted to examine associations between proximity to the nearest sports facilities and participation in the corresponding sports activities. Results The logisitic regression analyses showed that girls residing longer distances from the nearest gym were less likely to engage in indoor sports activities; a significant interaction between distances to gyms and level of urbanization was identified. Decomposition of the interaction term showed that for adolescent girls living in rural areas participation in indoor sports activities was positively associated with gym proximity. Proximity to tennis courts and indoor pools was not associated with participation in tennis or water sports, respectively. Conclusions Improved proximity to gyms is likely to be more important for female adolescents living in rural areas. PMID:24675689

Full Text Available To assess the relationship between proximity to specific sports facilities and participation in the corresponding sports activities for adolescents in Germany.A sample of 1,768 adolescents aged 11-17 years old and living in 161 German communities was examined. Distances to the nearest sports facilities were calculated as an indicator of proximity to sports facilities using Geographic Information Systems (GIS. Participation in specific leisure-time sports activities in sports clubs was assessed using a self-report questionnaire and individual-level socio-demographic variables were derived from a parent questionnaire. Community-level socio-demographics as covariates were selected from the INKAR database, in particular from indicators and maps on land development. Logistic regression analyses were conducted to examine associations between proximity to the nearest sports facilities and participation in the corresponding sports activities.The logistic regression analyses showed that girls residing longer distances from the nearest gym were less likely to engage in indoor sports activities; a significant interaction between distances to gyms and level of urbanization was identified.

Full Text Available Two important issues after a complete right forearm amputation are replantation and ongoing pain management. There are no reports of successful forearm replantation as a consequence of a crocodile bite. Here, we discuss our pain management in a case of complete forearm amputation after a bite from a saltwater crocodile (Crocodylus porosus, which necessitated six further operations to achieve successful replantation. Continuous infraclavicular brachial plexus block was effective for acute pain control in this case. We strongly recommend performing the block with an indwelling catheter under ultrasound guidance for higher accuracy and safety.

Fingertip replantation at the eponychial level with venous anastomosis: an anatomic study and clinical application.

Cheng, L; Chen, K; Chai, Y-M; Wen, G; Wang, C-Y

2013-11-01

We present an anatomic study of the vein distribution at the eponychial level, in order to standardize outpatient fingertip replantation. The cross sectional anatomy of 100 fingers was studied by dissection following dye injection. The distribution of the veins >0.3 mm was recorded on a pie-chart. Thirty fingers in 27 patients with fingertip amputations at the eponychial level were replanted by anastomosis of the palmar subcutaneous veins, to reconstruct the venous reflux of the amputated digits. The operations were aided by the anatomical study and confirmed that the palmar area is the preferred site for venous anastomosis Following a distal finger amputation at the level of the eponychial fold we propose starting the search for veins between the 3 to 5 o'clock or 7 to 9 o'clock positions, as these are the areas where there are most likely to be suitable veins.

Abstract Introduction: Amputation generates various biomechanical and structural changes, creating deficiencies in balance, equilibrium and proprioception. Altered proprioception affects the bodily-space component, as well as postural control and other physical qualities, which require a specific management with physiotherapy intervention. This research was conducted considering that proprioceptive assessment is an adequate and effective tool in physiotherapy but is poorly documented in the...

[Clinico-electromyographic evaluation of the state of motor units of the hand muscles replanted after traumatic amputation].

Science.gov (United States)

Rezkov, G I

1991-01-01

Needle electromyography was used to study motor units of the muscles leading away the thumb and little finger, replanted after traumatic amputation of the large segment of the upper limb in 34 patients. A direct relationship was discovered between the time of the appearance of action potentials of motor units (PMU), recovery of the movements, and trauma level. The appearance of clear PMU associated with movement recovery was recorded not earlier than 6-7 months after trauma. Analysis of PMU is a reliable criterion for the recovery of the own movements of the muscles and function of the neuromotor apparatus in patients with the replanted upper limb segment.

Sibbald, R. Gary; Martin, Carlos

2015-01-01

Background. Type 2 diabetes is the fourth leading cause of death in Guyana, South America. A complex, interprofessional, quality improvement intervention to improve foot and diabetes care was rolled out in two phases. Methods & Findings. Phase 1: Establishment of an Interprofessional Diabetic Foot Center (DFC) of Excellence to improve foot care and reduce diabetes-related amputations at the national referral hospital. Phase 2: Regionalization to cover 90% of the Guyanese population and expansion to include improved management of diabetes and hypertension. Fourteen key opinion leaders were educated and 340 health care professionals from 97 facilities trained. Eight centers for the evaluation and treatment of foot ulcers were established and 7567 people with diabetes evaluated. 3452 participants had foot screening and 48% were deemed high risk; 10% of these had undocumented foot ulcers. There was a 68% reduction in rate of major amputations (P diabetes with women (F/M = 2.09) and increased risk of major amputation in men [odds ratio 2.16 (95% CI 1.83, 2.56)] were documented. Conclusions. This intervention improved foot care with reduction in major amputations sustained over 5 years. PMID:26089901

Acute limb ischemia (ALI) is a highly morbid and fatal vascular emergency with little known about contemporary, long-term patient outcomes. The goal was to determine predictors of long-term mortality and amputation after open and endovascular treatment of ALI. A retrospective review of ALI patients at a single institution from 2005 to 2011 was performed to determine the impact of revascularization technique on 5-year mortality and amputation. For each main outcome 2 multivariable models were developed; the first adjusted for preoperative clinical presentation and procedure type, the second also adjusted for postoperative adverse events (AEs). A total of 445 limbs in 411 patients were treated for ALI. Interventions included surgical thrombectomy (48%), emergent bypass (18%), and endovascular revascularization (34%). Mean age was 68 ± 15 years, 54% were male, and 23% had cancer. Most patients presented with Rutherford classification IIa (54%) or IIb (39%). The etiology of ALI included embolism (27%), in situ thrombosis (28%), thrombosed bypass grafts (32%), and thrombosed stents (13%). Patients treated with open procedures had significantly more advanced ischemia and higher rates of postoperative respiratory failure, whereas patients undergoing endovascular interventions had higher rates of technical failure. Rates of postprocedural bleeding and cardiac events were similar between both treatments. Excluding Rutherford class III patients (n = 12), overall 5-year mortality was 54% (stratified by treatment, 65% for thrombectomy, 63% for bypass, and 36% for endovascular, P < 0.001); 5-year amputation was 28% (stratified by treatment, 18% for thrombectomy, 27% for bypass, and 17% for endovascular, P = 0.042). Adjusting for comorbidities, patient presentation, AEs, and treatment method, the risk of mortality increased with age (hazard ratio [HR] = 1.04, P < 0.001), female gender (HR = 1.50, P = 0.031), cancer (HR = 2.19, P < 0.001), fasciotomy (HR = 1.69, P = 0.204) in

Proximal Alternating Direction Method with Relaxed Proximal Parameters for the Least Squares Covariance Adjustment Problem

Directory of Open Access Journals (Sweden)

Minghua Xu

2014-01-01

Full Text Available We consider the problem of seeking a symmetric positive semidefinite matrix in a closed convex set to approximate a given matrix. This problem may arise in several areas of numerical linear algebra or come from finance industry or statistics and thus has many applications. For solving this class of matrix optimization problems, many methods have been proposed in the literature. The proximal alternating direction method is one of those methods which can be easily applied to solve these matrix optimization problems. Generally, the proximal parameters of the proximal alternating direction method are greater than zero. In this paper, we conclude that the restriction on the proximal parameters can be relaxed for solving this kind of matrix optimization problems. Numerical experiments also show that the proximal alternating direction method with the relaxed proximal parameters is convergent and generally has a better performance than the classical proximal alternating direction method.

Dynamic stability of running: The effects of speed and leg amputations on the maximal Lyapunov exponent

International Nuclear Information System (INIS)

Look, Nicole; Arellano, Christopher J.; Grabowski, Alena M.; Kram, Rodger; McDermott, William J.; Bradley, Elizabeth

2013-01-01

In this paper, we study dynamic stability during running, focusing on the effects of speed, and the use of a leg prosthesis. We compute and compare the maximal Lyapunov exponents of kinematic time-series data from subjects with and without unilateral transtibial amputations running at a wide range of speeds. We find that the dynamics of the affected leg with the running-specific prosthesis are less stable than the dynamics of the unaffected leg and also less stable than the biological legs of the non-amputee runners. Surprisingly, we find that the center-of-mass dynamics of runners with two intact biological legs are slightly less stable than those of runners with amputations. Our results suggest that while leg asymmetries may be associated with instability, runners may compensate for this effect by increased control of their center-of-mass dynamics

Little is known about the types of physical activities that older individuals with lower-limb loss perform, correlates of regular physical activity (PA), and barriers and facilitators to PA. We conducted an exploratory study in 158 older Veterans from the Pacific Northwest with a partial foot (35%), below-knee (39%) and above-knee (26%) amputation. Ninety-eight percent of survey respondents were male, on average 65 yr of age and 15 yr postamputation; 36% of amputations were trauma-related. The most commonly reported physical activities were muscle strengthening (42%), yard work and/or gardening (30%), and bicycling (11%). Forty-three percent were classified as physically active based on weekly moderate- and vigorous-intensity PA. History of vigorous preamputation PA was positively associated with being active, while low wealth and watching ≥5 h/d of television/videos were inversely associated. While pain- and resource-related barriers to PA were most frequently reported, only knowledge-related and interest/motivation-related barriers were inversely associated with being active. Family support and financial assistance to join a gym were the most commonly reported factors that would facilitate PA. To increase PA in the older amputee population, interventions should address motivational issues, knowledge gaps, and television watching; reduce financial barriers to exercising; and consider involving family members.

Correlation between social proximity and mobility similarity.

Human behaviors exhibit ubiquitous correlations in many aspects, such as individual and collective levels, temporal and spatial dimensions, content, social and geographical layers. With rich Internet data of online behaviors becoming available, it attracts academic interests to explore human mobility similarity from the perspective of social network proximity. Existent analysis shows a strong correlation between online social proximity and offline mobility similarity, namely, mobile records between friends are significantly more similar than between strangers, and those between friends with common neighbors are even more similar. We argue the importance of the number and diversity of common friends, with a counter intuitive finding that the number of common friends has no positive impact on mobility similarity while the diversity plays a key role, disagreeing with previous studies. Our analysis provides a novel view for better understanding the coupling between human online and offline behaviors, and will help model and predict human behaviors based on social proximity.

Modern treatment of infection and ischaemia to reduce major amputation in the diabetic foot.

Science.gov (United States)

Edmonds, Michael

2013-01-01

Diabetic patients suffer a high rate of amputation. There are two main reasons; infection which can spread rapidly leading to overwhelming tissue destruction and severe peripheral arterial disease. Studies that have stratified patients according to the presence or absence of both peripheral arterial disease and infection have shown significantly worse outcomes in patients with both peripheral arterial disease and infection. There have been two crucial significant advances in diabetic foot care to improve the outlook of these diabetic patients. First, there has been the realisation that diabetic foot patients experience repeated crises from the rapid onset infection and need a special form of easily accessible care within a multidisciplinary diabetic foot service to provide prompt treatment of infection before it progresses to necrosis. Secondly, within such a service, prompt diagnosis of ischaemia and urgent revascularisation has been established as a further important aspect of successful management. The critical factor in saving limbs is making a rapid diagnosis of infection and ischaemia and administering the appropriate treatment early. In this way speedy healing can be achieved and this can prevent patients from needing amputations.

Full Text Available To inform healthcare professionals of a rare serious reaction leading to leg amputation following intramuscular injection of iron dextran and report comments for preventing such reactions.A case of leg amputation following intramuscular injection of iron dextran reported to Iranian Pharmacovigilance Center was reviewed. Patient and reaction data was collected by assessing the reported yellow card, patient chart review and interviewing with patient and physicians. World Health Organization definition for serious reactions was used to determine the seriousness of the reaction. Naranjo algorithm was used to determine probability scale. The probability of the reaction was determined based on questionnaire of Schumock et al. The studied case is classified as a rare and serious but preventable reaction induced by intramuscular injection of iron dextran in a 32 year old woman. The probability of the reaction is appeared to be “probable” based on Naranjo algorithm. It seems that Iron dextran could cause serious and life threatening adverse effects. It is necessary for healthcare professionals to be informed of such rare but serious reaction in order to apply preventive actions.

Proximity friction reexamined

International Nuclear Information System (INIS)

1989-01-01

The contribution of inelastic excitations to radial and tangential friction form-factors in heavy-ion collisions is investigated in the frame-work of perturbation theory. The dependence of the form factors on the essential geometrical and level-density parameters of the scattering system is exhibited in a rather closed form. The conditions for the existence of time-local friction coefficients are discussed. Results are compared to form factors from other models, in particular the transfer-related proximity friction. For the radial friction coefficient the inelastic excitation mechanism seems to be the dominant contribution in peripheral collisions. (orig.)

Full Text Available This is a report of a 64-year-old man who had undergone a high tibial osteotomy (HTO 17 years ago of his right knee for medial compartment osteoarthritis; 5 days later, he received a below-knee amputation owing to a missed popliteal artery injury at the time of the HTO. We elected to perform a total knee replacement (TKR for progressive arthritis of the ipsilateral knee 17 years after the transtibial amputation. Although there is a plethora of literature regarding TKR in the contralateral knee of amputees, there is a paucity of data of TKR in the ipsilateral knee. Using medical search engines including Google Scholar and PubMed, we were only able to identify 4 case reports of TKR in the ipsilateral knee of below-knee amputees. This is the first description in the English literature that has the following rare pathology list: tricompartmental arthritis with a previous closing wedge HTO with a resultant truncated valgus tibia and short transtibial amputation.

We studied the influence of proximal geometry on the results of computational fluid dynamics (CFD). We made five models of different proximal geometry from three dimensional angiography of 63-year-old women with intracranial aneurysm. CFD results were analyzed as peak systolic velocity (PSV) at inlet and outlet as well as flow velocity profile at proximal level of internal carotid artery (ICA) aneurysm. Modified model of cavernous one with proximal tubing showed faster PSV at outlet than that at inlet. The PSV of outlets of other models were slower than that of inlets. The flow velocity profiles at immediate proximal to ICA aneurysm showed similar patterns in all models, suggesting that proximal vessel geometries could affect CFD results.

Segal, Ava D; Klute, Glenn K

2016-01-01

Thermal comfort remains a common problem for people with lower-limb amputation. Both donning a prosthesis and engaging in activity at room temperature can increase residual limb skin temperature; however, the effects of activity on skin temperature and comfort in more extreme environments remain unknown. We examined residual limb skin temperatures and perceived thermal comfort (PTC; 11-point Likert scale) of participants with unilateral transtibial amputation (n = 8) who were snowshoeing in a cold environment. Residual limb skin temperature increased by 3.9°C [3.0°C to 4.7°C] (mean difference [95% confidence interval (CI)], p < 0.001) after two 30 min exercise sessions separated by a 5 min rest session. Minimal cooling (-0.2°C [-1.1°C to 0.6°C]) occurred during the rest period. Similar changes in PTC were found for the residual limb, intact limb, and whole body, with a mean scale increase of 1.6 [1.1 to 2.1] and 1.3 [0.8 to 1.8] for the first and second exercise sessions, respectively (p < 0.001). Activity in a cold environment caused similar increases in residual limb skin temperature as those found in studies conducted at room temperature. Participants with amputation perceived warming as their skin temperature increased during exercise followed by the perception of cooling during rest, despite minimal associated decreases in skin temperature.

2017-06-08

Introduction. There is a lack in the worldwide literature of reports on the Neuromarkers of Post-Traumatic Stress Disorder (PTSD) in patients after bilateral hand amputation The aim of this study was to test a hypothesis regarding developing Post-Traumatic Stress Disorder (PTSD) in a patient after bilateral hand amputation with the use of Event Related Potentials (ERPs). On the basis of previous research, the amplitudes of P3 ERP components elicited in the cued GO/NOGO tasks have been chosen as candidates for neuromarkers of PTSD. Case study. A 24-year-old patient had undergone bilateral hand amputation 12 months previously. The patient was repeatedly operated on (he had undergone successful bilateral hand replantation) and despite the severity of the injuries, he recovered. However, the patient complained of flashbacks, anxiety and sleep difficulties. Specialist tests showed the presence of PTSD. The patient participated in the cued GO/NOGO task (Kropotov, 2009) with recording 19-channel EEG. P3 GO and NOGO waves in this task were found to be significantly smaller, in comparison to a group of healthy control subjects of the same age (N=23) taken from the HBI normative database (https://www.hbimed.com/). This observed pattern of ERP waves in the patient corresponds to the pattern found in PTSD patients. Conclusions. ERPs in a GO/NOGO task can be used in the assessment of the functional brain changes induced by chronic PTSD.

Objective: Peripheral arterial disease (PAD), as well as diabetic neuropathy, is a risk factor for the development of diabetic foot ulcers. The aim of this study was to evaluate differences and predictors of outcome parameters in patients with diabetic foot by stratifying these subjects according to the severity of PAD. Research design and methods: In a prospective study, patients with new diabetic foot ulcers have been treated and investigated by structured healthcare. Subjects were recruited between 1 January 2000 and 31 December 2007. All study participants underwent a 2-year follow-up observation period. The patients underwent a standardized examination and classification of their foot ulcers according to a modification of the University of Texas Wound Classification System. The severity of PAD was estimated by measurement of the ankle brachial index (ABI) and the continuous wave Doppler flow curve into undisturbed perfusion (0.9 diabetic foot were consecutively included into the study (69% male, mean age 66.3 ± 11.0 years, mean diabetes duration 15.8 ± 10.2 years). Major amputations (above the ankle) were performed in 4.7% of the patients. 22.1% of these subjects had decompensated PAD. These subjects had delayed ulcer healing, higher risk for major amputation [odds ratio (OR) 7.7, 95% confidence interval (CI) 2.8–21.2, p diabetic foot ulcers regarding to wound healing, major amputation and mortality.

We consider a bilevel problem involving two monotone equilibrium bifunctions and we show that this problem can be solved by a proximal point method with generalized proximal distances. We propose a framework for the convergence analysis of the sequences generated by the algorithm. This class of problems is very interesting because it covers mathematical programs and optimization problems under equilibrium constraints. As an application, we consider the problem of the stability and change dyna...

This clinical report describes the outpatient rehabilitation program for patients with multiple limb amputations enrolled in the Comprehensive Combat and Complex Casualty Care facility at the Naval Medical Center San Diego. Injury-specific data for 29 of these patients wounded by blast weaponry in Afghanistan in 2010 or 2011 were captured by the Expeditionary Medical Encounter Database at the Naval Health Research Center and were reviewed for this report. Their median Injury Severity Score was 27 (N = 29; range, 11-54). Patients averaged seven moderate to serious injuries (Abbreviated Injury Scale scores ≥2), including multiple injuries to lower limbs and injuries to the torso and/or upper limbs. All patients received care from numerous clinics, particularly physical therapy during the first 6 mo postinjury. Clinic use generally declined after the first 6 mo with the exception of prosthetic devices and repairs. The clinical team implemented the Mayo-Portland Adaptability Inventory, 4th Revision (MPAI-4) to assess functioning at outpatient program initiation and discharge (n = 23). At program discharge, most patients had improved scores for the MPAI-4 items assessing mobility, pain, and transportation, but not employment. Case reports described rehabilitation for two patients with triple amputations and illustrated multispecialty care and contrasting solutions for limb prostheses.

Dystrophic epidermolysis bullosa is a rare disease characterized by widespread blistering of the skin and mucous membranes, which may ultimately prompt limb amputation. In this context, the outcome of fitting a prosthesis to a chronically wounded stump is not well known. Our patient's experience (with 15 years of follow-up) should contribute to better knowledge of this topic. A 37-year-old man presented with severe dystrophic epidermolysis bullosa. Recurrent skin carcinoma had led to an amputation below the knee. Despite incessant development of blisters on the stump and the need for wound dressing and padding, the patient has been able to walk freely with a prosthesis and a cane. A large number of skin sarcomas were excised over the 15-year period of prosthesis use. Two falls have resulted in limb fractures. A new sarcoma on the stump marked the end of the use of the prosthesis. Despite the constant presence of wounds on the stump, amputees with dystrophic epidermolysis bullosa can successfully be fitted with a prosthesis.

Full Text Available This study is a documental descriptive analysis which aimed to verify the cost established in 2006, in relation to the hospitalization of 21 diabetic patients submitted to the lower limb amputation in a public hospital and the value transferred by the Unified Health System (SUS regarding this procedure. Among the studied patients, 57.14% were female and 42.86% male, aged 40 to 90 years. The time of diagnosis varied from 5 to 25 years. The average of hospitalization was 14 days per patient. The cost to the hospital was R$ 99,455.74, average cost per patient was R$ 4,735.98. The total amount transferred by SUS to the hospital was R$ 27,740.15, a cost 3.6 times lower than the hospital costs. The SUS transferring is in accordance with the predetermined values for its table of procedure. Prevention is the only alternative to reduce the rate of amputation and improve survival of diabetes patients. It is necessary an early diagnosis and better control of diabetes mellitus with appropriate government and institutional policies.

[A rare extra-skeletal myxoid chondrosarcoma of the lower leg - is amputation absolutely necessary].

Sarcomas represent less than 2 % of all malignancies. Special challenges are bone sarcomas in extra-skeletal localisation. The aim of this case report is to show the management of an extraordinary extra-skeletal myxoid chondrosarcoma based on a case report with references from the literature. After a delay in diagnostics for 1.5 years, an MRI scan taken in a 42-year-old male patient with progressive swelling of the left calf showed a soft-tissue tumour in the proximal part of the muscle. Histopathological investigation of a percutaneous biopsy revealed a chondrosarcoma. En-bloc-resection (R 0) of the rear superficial compartment was performed (specimen weight 1 370 g; tumour size 11.5 x 9.5 x 8 cm) leading to the definitive diagnosis of an extra-skeletal myxoid chondrosarcoma. The patient was discharged with a bland wound 8 days after surgery. At 4 weeks postoperatively, the patient received adjuvant radiotherapy with a 56-Gy boost. During the follow-up period of 28 months, there have been neither signs of local tumour recurrence nor distant metastases. The myxoid chondrosarcoma is a rare tumour lesion, and according to the literature, only 2 % occur outside of the skeleton. The accurate diagnostic and therapeutic algorithm allowed a precise preparation for surgery and made amputation obsolete. Compartment resection preserving the main neurovascular bundles as well as enabling an early mobilisation resulted in both sufficient radical resection status and adequate postoperative motor function. Intraoperative clip-marking of the former tumour bed is considered a key point for the focused radiotherapy. Each persistent soft tissue swelling must be appropriately diagnosed using adequate imaging and even biopsy (in case of a doubtful finding), which should be performed with definitive surgery in mind.

Is it possible to develop and externally validate risk prediction equations to estimate the 10 year risk of blindness and lower limb amputation in patients with diabetes aged 25-84 years? This was a prospective cohort study using routinely collected data from general practices in England contributing to the QResearch and Clinical Practice Research Datalink (CPRD) databases during the study period 1998-2014. The equations were developed using 763 QResearch practices (n=454,575 patients with diabetes) and validated in 254 different QResearch practices (n=142,419) and 357 CPRD practices (n=206,050). Cox proportional hazards models were used to derive separate risk equations for blindness and amputation in men and women that could be evaluated at 10 years. Measures of calibration and discrimination were calculated in the two validation cohorts. Risk prediction equations to quantify absolute risk of blindness and amputation in men and women with diabetes have been developed and externally validated. In the QResearch derivation cohort, 4822 new cases of lower limb amputation and 8063 new cases of blindness occurred during follow-up. The risk equations were well calibrated in both validation cohorts. Discrimination was good in men in the external CPRD cohort for amputation (D statistic 1.69, Harrell's C statistic 0.77) and blindness (D statistic 1.40, Harrell's C statistic 0.73), with similar results in women and in the QResearch validation cohort. The algorithms are based on variables that patients are likely to know or that are routinely recorded in general practice computer systems. They can be used to identify patients at high risk for prevention or further assessment. Limitations include lack of formally adjudicated outcomes, information bias, and missing data. Patients with type 1 or type 2 diabetes are at increased risk of blindness and amputation but generally do not have accurate assessments of the magnitude of their individual risks. The new algorithms calculate

Full Text Available This is a post hoc analysis of quality of life in diabetic neuropathy patients in a cross-sectional survey performed in 2012 in Romania, using the Norfolk QOL-DN in which 21,756 patients with self-reported diabetes were enrolled. This current analysis aims to expand research on the diabetic foot and to provide an update on the number of foot ulcers found in Romania. Of the 21,174 patients included in this analysis, 14.85% reported a history of foot ulcers and 3.60% reported an amputation. The percentage of neuropathy patients with foot ulcers increased with age; the lowest percentage was observed in the 20–29-year age group (6.62% and the highest in the 80–89-year age group (17.68%. The highest number of amputations was reported in the 70–79-year age group (largest group. Compared to patients without foot ulcers, those with foot ulcers had significantly higher scores for total DN and all its subdomains translating to worse QOL (p<0.001. This analysis showed a high rate of foot ulcers and amputations in Romanian diabetic patients. It underscores the need for implementation of effective screening and educational programs.

A 50-year-old surgeon was working with his electrical circle saw as a do-it-yourselfer. He was alone, nobody witnessed his mishap when he amputated his left index finger. He claimed high financial compensation from two accident insurance companies because of his disability. A long series of medical expertises followed. The juridical procedures took 12 years in total. All higher authorities had to deal with the forensic medical implications. Finally, the high court (Bundesgerichtshof) decided that the complainant would receive no compensation because he gave two very different descriptions. Concerning the reconstruction of the accident, the first version was unlikely from a biomechanical point of view. The decision of the court was solely based on the violation of the obligation to give a clear presentation of the course of events (Obliegenheitsverletzung).

Modified toe pulp fillet flap coverage: Better wound healing and satisfactory length preservation.

Science.gov (United States)

Baek, Sang Oon; Suh, Hyo Wan; Lee, Jun Yong

2018-01-01

Amputation is commonly performed for toe necrosis secondary to peripheral vascular diseases, such as diabetes mellitus. When amputating a necrotic toe, preservation of the bony structure is important for preventing the collapse of adjacent digits into the amputated space. However, in the popular terminal Syme's amputation technique, partial amputation of the distal phalanx could cause increased tension on the wound margin. Herein, we introduce a new way to resect sufficient bony structure while maintaining the normal length, based on a morphological analysis of the toes. Unlike the pulp of the finger in the distal phalanx, the toe has abundant teardrop-shaped pulp tissue. The ratio of the vertical length to the longitudinal length in the distal phalanx was compared between the toes and fingers. Amputation was performed at the proximal interphalangeal joint level. Then, a mobilizable pulp flap was rotated 90° cephalad to replace the distal soft tissue defect. This modified toe fillet flap was performed in 5 patients. The toe pulp was found to have a vertically oriented morphology compared to that of the fingers, enabling length preservation through cephalad rotation. All defects were successfully covered without marginal ischemia. While conventional toe fillet flap coverage focuses on the principle of length preservation as the first priority, our modified method takes both wound healing and length into account. The fattiest part of the pulp is advanced to the toe tip, providing a cushioning effect and enough length to substitute for phalangeal bone loss. Our modified method led to satisfactory functional and aesthetic outcomes.

Fall incidence and associated risk factors among people with a lower limb amputation during various stages of recovery - a systematic review.

The objective of this study was to estimate fall incidence and describe associated risk factors among people with a lower limb amputation (LLA) during various stages of recovery: the surgical ward, in-patient rehabilitation and return to community life. A systematic search of relevant English language articles was performed using PubMed and EMBASE. Out of 310 initial "hits," six retrospective cohort studies, one prospective cohort study and eleven cross-sectional studies from which fall incidence and risk factors could be extracted, were selected for critical review. Fall incidence and associated risk factors were extracted and analyzed in the context of various clinical stages of recovery after amputation. The studies were evaluated for quality using the "Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies." Results showed that during all stages of recovery, people with a LLA are at increased risk of falling compared with able-bodied individuals, as well as other clinical populations. Each stage of recovery is associated with different fall risk factors. The current review is limited mainly by the paucity of studies on the topic. Specialised care focusing on the most relevant risk factors for each stage of recovery may enhance fall prevention during post-fall recovery. Implications for rehabilitation •  People with a lower limb amputation are at a high risk of falling in all stages of their clinical course.      •  Health professionals should be aware that people with a lower limb amputation in the first 4 years ofamputation or with four or more health-related problems are at an increased risk.      •  Health professionals should also be aware that increased gait variability, excess confidence in balance andwalking abilities and less cautious stair walking, impose an elevated risk of falling and should focus theirefforts in reducing these factors.

Nonarterialized Venous Replantation of Part of Amputated Thumb—A Case Report and Review of the Literature

Science.gov (United States)

Kalimuthu, Ramasamy

2006-01-01

Since the first successful replantation of a human thumb reported by Komatsu and Tamai in 1968, thousands of severed digits and body parts have been successfully salvaged. Restoration of anatomic form and function are the goals of replantation after traumatic tissue amputation. Regardless of anatomic location, methods include microsurgical replantation and nonmicrosurgical replantation, such as composite graft techniques. Numerous techniques to maximize tissue survival after revascularization have been described, including “pocket procedures” to salvage composite grafts, interposition vein grafts, and medicinal leeches to name a few. Artery-to-venous anastomoses have been performed with successful “arterialization” of the distal venous system in fingertip replantation. Although there is documented survival of free venous cutaneous flaps, to our knowledge this is the first report of a replanted composite body part (bone, tendon, soft tissues, and skin) utilizing exclusively multiple, microvascular, nonarterialized venous–venous anastomoses. We present a patient with an isolated band saw fillet amputation to the back of the thumb at the metacarpal–phalangeal joint region, resulting in a composite graft composed of bone, tendon, soft tissue, and skin. The hand wound provided no viable regional arterial inflow source, but there were multiple good caliber superficial veins present. The amputated tissues were replanted and revascularized by using only venous blood flow. The replanted part survival was 100% with excellent function of the digit. We conclude that a hand composite body part involving bone, tendon, soft tissues, and skin can survive replantation with a strict venous blood supply if sufficient good caliber, microvascular, venous–venous anastomoses are performed, granted that arterial inflow options are not available. This is an isolated case, yet introduces a new way of thinking regarding tissue replantation. PMID:18780032

Up to now, a cosmetic glove was the most common method for managing transmetacarpal (TMC) and carpometacarpal (CMC) amputations, but it is devoid of markings and body color. At this amputation level, it is very difficult to fit a functional prosthesis because of the short available length, unsightly shape, grafted skin, contracture and lack of functional prosthetic options. A 30-year-old male came to our clinic with amputation at the 1st to 4th carpometacarpal level and a 5th metacarpal that was projected laterally and fused with the carpal bone. The stump had grafted skin, redness, and an unhealed suture line. He complained of pain projected over the metacarpal and suture area. The clinical team members decided to fabricate a custom-made silicone hand prosthesis to accommodate the stump, protect the grafted skin, improve the hand's appearance and provide some passive function. The custom silicone hand prosthesis was fabricated with modified flexible wires to provide passive interphalangeal movement. Basic training, care and maintenance instructions for the prosthesis were given to the patient. The silicone hand prosthesis was able to restore the appearance of the lost digits and provide some passive function. His pain (VAS score) was reduced. Improvement in activities of daily living was found in the DASH questionnaire and Jebsen-Taylor Hand Function test. A silicone glove is a good option for more distal amputations, as it can accommodate any deformity, protect the skin, enhance the appearance and provide functional assistance. This case study provides a simple method to get passively movable fingers after proximal hand amputation. Copyright © 2016. Published by Elsevier Masson SAS.

Methods: Seventeen patients after unilateral lower limb amputation secondary to trauma were enrolled. Ten patients had chronic PLP, while the other seven patients had no PLP. Tactile-sensation threshold, cold- and warm-sensation thresholds, cold- and heat-pain thresholds, electrical-sensation threshold (EST, and electrical-pain threshold on the distal residual limb and the symmetrical site on the sound limb were measured in all tested patients. Their thresholds were compared within the PLP and non-PLP group, and between the groups. Results: The novel findings included: 1 electrical-pain threshold was only decreased in the sound limb in the PLP group and there was no difference between two limbs in the non-PLP group, suggesting central sensitization in patients with PLP; and 2 EST was increased on the affected limb as compared to the sound limb within the PLP group, but there were no significant differences in EST between the PLP and non-PLP group. There were in general no significant differences in other tested thresholds within the groups and between groups. Conclusion: Our results demonstrate central sensitization in the patients with PLP after traumatic limb amputation. Keywords: central sensitization, pain threshold, human

Two studies investigated the relationship between casino proximity and gambling participation, expenditure, and pathology. In Study 1, 8,842 participants were categorized into 1 of 4 driving distances from their home to the nearest casino in the province of Quebec: 0-100 km, 100.01-200 km, 200.01-300 km, or 300.01-981 km. In Study 2, 5,158 participants, who lived within a 100-km driving distance from the Montreal casino, were classified into 1 of 5 equidistant, 20-km driving distances. A survey company interviewed participants regarding their gambling habits. Results indicated a positive link between casino proximity and gambling participation (at the provincial and Montreal levels) and expenditure (at the provincial level only) but no link with the current prevalence rate of probable pathological gambling or of problem gambling. In a setting in which many types of gambling activities are available, casino proximity in itself does not appear to explain the rate of gambling-related problems. It is necessary to continue prospective research on exposure and adaptation theories as potential explanations for the development of pathological gambling. 2008 APA

2015-04-01

The purpose of this study was to evaluate whether the new Society for Vascular Surgery (SVS) Wound, Ischemia, and foot Infection (WIfI) classification system correlates with important clinical outcomes for limb salvage and wound healing. A total of 201 consecutive patients with threatened limbs treated from 2010 to 2011 in an academic medical center were analyzed. These patients were stratified into clinical stages 1 to 4 on the basis of the SVS WIfI classification. The SVS objective performance goals of major amputation, 1-year amputation-free survival (AFS) rate, and wound healing time (WHT) according to WIfI clinical stages were compared. The mean age was 58 years (79% male, 93% with diabetes). Forty-two patients required major amputation (21%); 159 (78%) had limb salvage. The amputation group had a significantly higher prevalence of advanced stage 4 patients (P healing. As the clinical stage progresses, the risk of major amputation increases, 1-year AFS declines, and WHT is prolonged. We further demonstrated benefit of revascularization to improve WHT in selected patients, especially those in stage 3. Future efforts are warranted to incorporate the SVS WIfI classification into clinical decision-making algorithms in conjunction with a comorbidity index and anatomic classification.

mortality compared with the patients who did not receive arthrodesis or amputation (HR, 1.00 [0.91-1.10], p = 0.971). The findings of this study suggest that clinicians may be more aggressively attempting to preserve the knee even in the face of chronic prosthetic joint infection but also show that a greater number of revisions is associated with a greater risk of subsequent AKA or arthrodesis. The results also suggest that recommending centers with a high volume of joint arthroplasties may be a way to reduce the risk of the salvage procedures. Level III, therapeutic study.

Use of Ganga Hospital Open Injury Severity Scoring for determination of salvage versus amputation in open type IIIB injuries of lower limbs in children-An analysis of 52 type IIIB open fractures.

Science.gov (United States)

Venkatadass, K; Grandhi, Tarani Sai Prasanth; Rajasekaran, S

2017-11-01

Open injuries in children are rare compared to adults. In children with major open injuries, there is no specific scoring system to guide when to amputate or salvage the limb. The use of available adult scoring systems may lead to errors in management. The role of Ganga Hospital Open Injury Severity Scoring (GHOISS) for open injuries in adults is well established and its applicability for pediatric open injuries has not been studied. This study was done to analyse the usefulness of GHOISS in pediatric open injuries and to compare it with MESS(Mangled Extremity Severity Score). All children (0-18 years) who were admitted with Open type IIIB injuries of lower limbs between January 2008 and March 2015 were included. MESS and GHOISS were calculated for all the patients. There were 50 children with 52 type IIIB Open injuries of which 39 had open tibial fractures and 13 had open femur fractures. Out of 52 type IIIB open injuries, 48 were salvaged and 4 were amputated. A MESS score of 7 and above had sensitivity of 25% for amputation while GHOISS of 17 and above was found to be more accurate for determining amputation with sensitivity of 75% and specificity of 93.75%. GHOISS is a reliable predictor of injury severity in type IIIB open fractures in children and can be used as a guide for decision-making. The use of MESS score in children has a lower predictive value compared to GHOISS in deciding amputation versus salvage. A GHOISS of 17 or more has the highest sensitivity and specificity to predict amputation. Copyright © 2017 Elsevier Ltd. All rights reserved.

Proximal tubular hypertrophy and enlarged glomerular and proximal tubular urinary space in obese subjects with proteinuria.

Directory of Open Access Journals (Sweden)

Ana Tobar

Full Text Available BACKGROUND: Obesity is associated with glomerular hyperfiltration, increased proximal tubular sodium reabsorption, glomerular enlargement and renal hypertrophy. A single experimental study reported an increased glomerular urinary space in obese dogs. Whether proximal tubular volume is increased in obese subjects and whether their glomerular and tubular urinary spaces are enlarged is unknown. OBJECTIVE: To determine whether proximal tubules and glomerular and tubular urinary space are enlarged in obese subjects with proteinuria and glomerular hyperfiltration. METHODS: Kidney biopsies from 11 non-diabetic obese with proteinuria and 14 non-diabetic lean patients with a creatinine clearance above 50 ml/min and with mild or no interstitial fibrosis were retrospectively analyzed using morphometric methods. The cross-sectional area of the proximal tubular epithelium and lumen, the volume of the glomerular tuft and of Bowman's space and the nuclei number per tubular profile were estimated. RESULTS: Creatinine clearance was higher in the obese than in the lean group (P=0.03. Proteinuria was similarly increased in both groups. Compared to the lean group, the obese group displayed a 104% higher glomerular tuft volume (P=0.001, a 94% higher Bowman's space volume (P=0.003, a 33% higher cross-sectional area of the proximal tubular epithelium (P=0.02 and a 54% higher cross-sectional area of the proximal tubular lumen (P=0.01. The nuclei number per proximal tubular profile was similar in both groups, suggesting that the increase in tubular volume is due to hypertrophy and not to hyperplasia. CONCLUSIONS: Obesity-related glomerular hyperfiltration is associated with proximal tubular epithelial hypertrophy and increased glomerular and tubular urinary space volume in subjects with proteinuria. The expanded glomerular and urinary space is probably a direct consequence of glomerular hyperfiltration. These effects may be involved in the pathogenesis of obesity

Fractures of the proximal humerus

Fractures of the proximal humerus have been diagnosed and managed since the earliest known surgical texts. For more than four millennia the preferred treatment was forceful traction, closed reduction, and immobilization with linen soaked in combinations of oil, honey, alum, wine, or cerate......, classification of proximal humeral fractures remains a challenge for the conduct, reporting, and interpretation of clinical trials. The evidence for the benefits of surgery in complex fractures of the proximal humerus is weak. In three systematic reviews I studied the outcome after locking plate osteosynthesis...

We examined whether physical proximity to supermarkets or supermarket price was more strongly associated with obesity risk. The Seattle Obesity Study (SOS) collected and geocoded data on home addresses and food shopping destinations for a representative sample of adult residents of King County, Washington. Supermarkets were stratified into 3 price levels based on average cost of the market basket. Sociodemographic and health data were obtained from a telephone survey. Modified Poisson regression was used to test the associations between obesity and supermarket variables. Only 1 in 7 respondents reported shopping at the nearest supermarket. The risk of obesity was not associated with street network distances between home and the nearest supermarket or the supermarket that SOS participants reported as their primary food source. The type of supermarket, by price, was found to be inversely and significantly associated with obesity rates, even after adjusting for individual-level sociodemographic and lifestyle variables, and proximity measures (adjusted relative risk=0.34; 95% confidence interval=0.19, 0.63) Improving physical access to supermarkets may be one strategy to deal with the obesity epidemic; improving economic access to healthy foods is another.

The Society for Vascular Surgery Wound, Ischemia, and foot Infection (WIfI) threatened limb classification has been shown to correlate well with risk of major amputation and time to wound healing in heterogeneous diabetic and nondiabetic populations. Major amputation continues to plague the most severe stage 4 WIfI patients, with 1-year amputation rates of 20% to 64%. Our aim was to determine the association between WIfI stage and wound healing and major amputation among patients with diabetic foot ulcers (DFUs) treated in a multidisciplinary setting. All patients presenting to our multidisciplinary DFU clinic from July 2012 to December 2015 were enrolled in a prospective database. Wound healing and major amputation were compared for patients stratified by WIfI classification. There were 217 DFU patients with 439 wounds (mean age, 58.3 ± 0.8 years; 58% male, 63% black) enrolled, including 28% WIfI stage 1, 11% stage 2, 33% stage 3, and 28% stage 4. Peripheral arterial disease and dialysis were more common in patients with advanced (stage 3 or 4) wounds (P ≤ .05). Demographics of the patients, socioeconomic status, and comorbidities were otherwise similar between groups. There was a significant increase in the number of active wounds per limb at presentation with increasing WIfI stage (stage 1, 1.1 ± 0.1; stage 4, 1.4 ± 0.1; P = .03). Mean wound area (stage 1, 2.6 ± 0.6 cm 2 ; stage 4, 15.3 ± 2.8 cm 2 ) and depth (stage 1, 0.2 ± 0.0 cm; stage 4, 0.8 ± 0.1 cm) also increased progressively with increasing wound stage (P healing (P healing time was 190 ± 17 days, and risk of major amputation at 1 year was 5.7% ± 3.2%. Among patients with DFU, the WIfI classification system correlated well with wound healing but was not associated with risk of major amputation at 1 year. Although further prospective research is warranted, our results suggest that use of a multidisciplinary approach for DFUs may augment healing time and reduce amputation

Using a custom mobile application to evaluate the reliability and validity of the Component Timed-Up-and-Go test to assess prosthetic mobility in people with lower limb amputation. Cross-sectional design. National conference for people with limb loss. A total of 118 people with non-vascular cause of lower limb amputation participated. Subjects had a mean age of 48 (±13.7) years and were an average of 10 years post amputation. Of them, 54% ( n = 64) of subjects were male. None. The Component Timed-Up-and-Go was administered using a mobile iPad application, generating a total time to complete the test and five component times capturing each subtask (sit to stand transitions, linear gait, turning) of the standard timed-up-and-go test. The outcome underwent test-retest reliability using intraclass correlation coefficients (ICCs) and convergent validity analyses through correlation with self-report measures of balance and mobility. The Component Timed-Up-and-Go exhibited excellent test-retest reliability with ICCs ranging from .98 to .86 for total and component times. Evidence of discriminative validity resulted from significant differences in mean total times between people with transtibial (10.1 (SD: ±2.3)) and transfemoral (12.76 (SD: ±5.1) amputation, as well as significant differences in all five component times ( P < .05). Convergent validity of the Component Timed-Up-and-Go was demonstrated through moderate correlations with the PLUS-M ( r s  = -.56). The Component Timed-Up-and-Go is a reliable and valid clinical tool for detailed assessment of prosthetic mobility in people with non-vascular lower limb amputation. The iPad application provided a means to easily record data, contributing to clinical utility.

The number of periprosthetic proximal femoral fractures is expected to increase with the increasing prevalence of hip arthroplasties. While native hip fractures have a well-known association with mortality, there are currently limited data on this outcome among the subset of patients with periprosthetic proximal femoral fractures. Using the New York Statewide Planning and Research Cooperative System, we identified patients from 60 to 99 years old who were admitted to a hospital in the state with a periprosthetic proximal femoral fracture (n = 1,655) or a native hip (femoral neck or intertrochanteric) fracture (n = 97,231) between 2006 and 2014. Within the periprosthetic fracture cohort, the indication for the existing implant was not available in the data set. We used mixed-effects regression models to compare mortality at 1 and 6 months and 1 year for periprosthetic compared with native hip fractures. The risk of mortality for patients who sustained a periprosthetic proximal femoral fracture was no different from that for patients who sustained a native hip fracture at 1 month after injury (3.2% versus 4.6%; odds ratio [OR], 0.90; 95% confidence interval [CI], 0.68 to 1.19; p = 0.446), but was lower at 6 months (3.8% versus 6.5%; OR, 0.74; 95% CI, 0.57 to 0.95; p = 0.020) and 1 year (9.7% versus 15.9%; OR, 0.71; 95% CI, 0.60 to 0.85; p accounting for age and comorbidities.

Diabetic foot disease is associated with major morbidity, mortality, costs, and reduction of a person's quality of life. Investigating the epidemiology of diabetic foot disease is the backbone of diabetic foot research and clinical practice, yet the full burden of diabetic foot disease in Australia is unknown. This study aims to describe the protocol for a systematic review of the epidemiology of diabetic foot disease and diabetes-related lower-extremity amputation in Australia. The systematic review will be performed according to the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. PubMed and EMBASE will be searched for publications in any language and without restrictions to date. Two independent investigators will screen publications for eligibility, with publications reporting Australian population-based incidence or prevalence of diabetic foot disease or diabetes-related lower-extremity amputation to be included. Additionally, a forward literature search will be performed in Google Scholar, and a grey literature search will be performed to identify government publications. Quality assessment will be performed using customised checklists. The summary statistic used for each study will be an incidence or prevalence proportion of diabetic foot disease or diabetes-related lower-extremity amputation. The standard error for each proportion will be calculated. A meta-analysis will be performed when three or more publications of adequate quality, reporting on similar outcomes and in similar populations, are identified. The results of this systematic review can be used to adequately inform stakeholders in the field of diabetic foot disease on the extent of the problem in incidence and prevalence of diabetic foot disease in Australia, and to help guide appropriate use of resources to reduce the burden of this disease.

Limb salvage treatment vs. amputation in sarcoma

Directory of Open Access Journals (Sweden)

Motamedi M

1993-05-01

Full Text Available Many years ago the treatment of sarcoma was radiotherapy up to 2000-4000 rad. This treatment was very complicated, due to producing neoplasm after radiotherapy. By this method of treatment of osteosarcoma, the rate of survival became about 20% (two years. The second method of treatment was chemotherapy for a period of 2-5 weeks that amputation was performed afterwards. By chemotherapy, the rate of being alive reached up to 25-27% (five years. Right now, the best treatment for sarcoma is limb salvage. In our report, the chance of being alive in chondrosarcoma was about four years. This was nearly the same as that of the other institutes in the world especially in America, Europe, and Japan. The rate of recurrence was also more than that from different parts of the world. The survival rate in osteosarcomatic patients was about two years less for males the females, and it was more in tall people than short ones. The survival rate of the patients with giant cell tumor was more than osteosarcoma up to five years, and it has no recurrence or metastasis

Objective: to explore the initial outcome and efficacy of S 3 proximal humerus locking plate in the treatment of proximal humerus fractures. Methods: Twenty-two patients with proximal humerus fracture were treated with the S 3 proximal humerus locking plate. Most of the fractures were complex, two-part (n=4), three-part (n=11) and four-part (n=7) fractures according to the Neer classification of the proximal humerus fractures. Results: All patients were followed up for 3∼15 months. There were no complications related to the implant including loosening or breakage of the plate. Good and excellent results were documented in 17 patients fair results in 4 patients according the Neer scores of shoulder. Conclusion: New design concepts of S 3 proximal humerus plate provide the subchondral support and the internal fixation support. With the addition of the proper exercise of the shoulder joint, the outcomes would be satisfied. (authors)

Novel Treatment of a Scapholunate Ligament Injury with Proximal Pole Scaphoid Nonunion

Gaspar, Michael P.; Kane, Patrick M.; Jacoby, Sidney M.; Culp, Randall W.

2016-01-01

Background  Nonunion of scaphoid proximal pole fractures presents a challenging management dilemma to hand surgeons. This problem is further complicated in the uncommon concurrence of scapholunate (SL) ligament disruption. Case Description  A 39-year-old male patient presented with new-onset wrist pain following a remote history of a proximal pole scaphoid fracture sustained as a teenager, which was treated nonoperatively. Six months before presentation, the patient sustained a fall while snowboarding. The patient was found to have a chronic nonunion of his scaphoid proximal pole with an associated SL ligament disruption. As the proximal fragment was too small to be amenable to fixation, the patient was treated with an arthroscopic partial scaphoid excision and SL ligament reconstruction using a scapholunateintercarpal screw placed percutaneously. At 26 months, the patient exhibited no pain, near-normal strength, and wrist motion, and expressed a high-level of satisfaction from his surgery. Literature Review  Although cases of SL ligament disruption with concomitant proximal scaphoid fractures have been reported, to our knowledge, this is the first report of SL ligament rupture occurring in the setting of a preexisting proximal pole scaphoid nonunion. Clinical Relevance  We report the use of SL ligament reconstruction augmented with intercarpal screw fixation, and excision of the proximal pole scaphoid nonunion. This minimallyinvasive approach may be a particularly useful option in young, active patients such as our own, where a motion-sacrificing salvage procedure would be less than ideal. PMID:27616829

Investigation of an alleged mechanism of finger injury in an automobile crash.

Stacey, Stephen; Kent, Richard

2006-07-01

This investigation centers on the case of an adult male whose finger was allegedly amputated by the steering wheel of his car during a crash. The subject claimed to have been driving with his left index finger inserted through a hole in the spoke of his steering wheel and was subsequently involved in an offset frontal collision with a tree. The finger was found to be cleanly severed at the mid-shaft of the proximal phalanx after the crash. This injury was alleged to have been caused by inertial loading from the rotation of the steering wheel during the crash. To determine whether this injury mechanism was plausible, three laboratory tests representing distinct loading scenarios were carried out with postmortem human surrogates loaded dynamically by the subject's steering wheel. It was found that the inertial loads generated in this loading scenario are insufficient to amputate the finger. Additionally, artificially constraining the finger to force an amputation to occur revealed that a separation at the proximal interphalangeal joint occurs rather than a bony fracture of the proximal phalanx. Based on these biomechanical tests, it can be concluded that the subject's injury did not occur during the automobile crash in question. Furthermore, it can be shown that the injury was self-inflicted to fraudulently claim on an insurance policy.

The increased susceptibility to fracture of root canal- and post-treated teeth is less affected by alterations of the dentin structure, but seems to crucially depend on the loss of coronal tooth substance. The surface, available for adhesion of the composite material in the root canal and in the coronal part of the tooth, is assumed to be of key importance for the fracture resistance. Thus, an appropriate three-dimensional method should be identified to determine the adhesive surface with necessary precision. For this purpose, severely decayed teeth were simulated decapitating clinical crowns. After root canal filling and post space preparation, impressions of the root canal and the amputation surface were obtained using silicone. Micro computed tomography scans of these impressions were acquired. For one selected specimen, an additional high-resolution scan was recorded at a synchrotron radiation source. Software of ImageLab served for the extraction of the amputation interface, the post surface and the post volume from the tomography data, which have been finally correlated with the Young's modulus and the maximal load derived from mechanical tests. The morphological parameters show a realistic relationship to the mechanical tests performed after the restoration treatments and are consequently important for improving the dental skills.

Preliminary study on leadership proximity

Directory of Open Access Journals (Sweden)

Ghinea Valentina Mihaela

2017-07-01

Full Text Available In general, it is agreed that effective leadership requires a certain degree of proximity, either physical or mental, which enables leaders to maintain control over their followers and communicate their vision. Although we agree with the leadership proximity principles which states that leaders are able to efficiently serve only those people with whom they interact frequently, in this article we focus instead on the disadvantages of being too close and the way in which close proximity can actually hurt the effectiveness of leadership. The main effects that we discuss regard the way in which proximity and familiarity allow followers to see the weaknesses and faults of the leader much more easily and thus diminish the leader’s heroic aura, and the emotional bias that results from a leader being too familiar with his followers which will impede the process of rational decision making. As a result, we argue that there exists a functional proximity which allows the leader the necessary space in which to perform effective identity work and to hide the backstage aspects of leadership, while also allowing him an emotional buffer zone which will enable him to maintain the ability to see clearly and make rational decisions.

SGLT2 Inhibitors: Glucotoxicity and Tumorigenesis Downstream the Renal Proximal Tubule?

Science.gov (United States)

Bertinat, Romina; Nualart, Francisco; Yáñez, Alejandro J

2016-08-01

At present, diabetes mellitus is the main cause of end-stage renal disease. Effective glycaemic management is the most powerful tool to delay the establishment of diabetic complications, such as diabetic kidney disease. Together with reducing blood glucose levels, new anti-diabetic agents are expected not only to control the progression but also to restore known defects of the diabetic kidney. Sodium-glucose co-transporter 2 (SGLT2) inhibitors are promising anti-diabetic agents that reduce hyperglycaemia by impairing glucose reabsorption in proximal tubule of the kidney and increasing glucosuria. SGLT2 inhibitors have shown to reduce glucotoxicity in isolated proximal tubule cells and also to attenuate expression of markers of overall kidney damage in experimental animal models of diabetes, but the actual renoprotective effect for downstream nephron segments is still unknown and deserves further attention. Here, we briefly discuss possible undesired effects of enhanced glucosuria and albuminuria in nephron segments beyond the proximal tubule after SGLT2 inhibitor treatment, offering new lines of research to further understand the renoprotective action of these anti-diabetic agents. Strategies blocking glucose reabsorption by renal proximal tubule epithelial cells (RPTEC) may be protective for RPTEC, but downstream nephron segments will still be exposed to high glucose and albumin levels through the luminal face. The actual effect of constant enhanced glucosuria over distal nephron segments remains to be established. J. Cell.

Full Text Available Objective : To evaluate the quality of life related to the spine in patients with proximal femoral fractures. Methods : Study conducted in a tertiary public hospital in patients with proximal femoral fractures caused by low-energy trauma, through the Oswestry Disability Index questionnaire to asses complaints related to the spine at the time of life prior to the femoral fracture. The thoracic and lumbar spine of patients were also evaluated applying the radiographic index described by Gennant (Spinal Deformity Index, which assesses the number and severity of fractures. Results : Seventeen subjects completed the study. All had some degree of vertebral fracture. Patients were classified in the categories of severe and very severe disability in the questionnaire about quality of life. It was found that the higher SDI, the better the quality of life. Conclusion : There is a strong association of disability related to the spine in patients with proximal femoral fracture, and this complaint must be systematically evaluated in patients with appendicular fracture.

Any defect in the extremities of the body can affect different life aspects. The purpose of this study was to investigate the effect of Roy's adaptation model-guided education on coping strategies of the veterans with lower extremities amputation. In a double-blind randomized controlled clinical trial, 60 veterans with lower extremities amputation referring to Kowsar Orthotics and Prosthetics Center of Veterans Clinic in Tehran, Iran were recruited using convenience method and randomly assigned to intervention and control groups in 2013-2014. Lazarus and Folkman coping strategies questionnaire was used to collect the data. After completing the questionnaires in both groups, maladaptive behaviours were determined in the intervention group and an education program based on Roy's adaptation model was implemented. After 2 months, both groups completed the questionnaires again. Data were analyzed using SPSS software. Independent T-test showed that the score of the dimensions of coping strategies did not have a statistically significant difference between the intervention and control groups in the pre-intervention stage (P>0.05). This test showed a statistically significant difference between the two groups in the post-intervention stage in terms of the scores of different dimensions of coping strategies (P>0.05), except in dimensions of social support seeking and positive appraisal (P>0.05). The findings of this research indicated that the Roy's adaptation model-guided education improved the majority of coping strategies in veterans with lower extremities amputation. It is recommended that further interventions based on Roy's adaptation model should be performed to improve the coping of the veterans with lower extremities amputation. IRCT2014081118763N1.

In patients with a transfemoral amputation socket-related problems are associated with reduced prosthetic use, activity, and quality of life. Furthermore, gait asymmetries are present that may explain secondary complaints. Bone-anchored prostheses (BAPs) may help these patients. Two types of BAP are available, screw and press-fit implants. Rehabilitation following surgery for a press-fit BAP is poorly described. To describe a rehabilitation program designed to minimize compensation strategies and increase activity using a case-report of an active, 70-year-old man with a traumatic transfemoral amputation who had used a socket prosthesis for 52 years and received a press-fit BAP [Endo-Exo Femoral Prosthesis - EEFP]. A 13-week physiotherapy program. Outcomes were assessed before surgery, at the end of rehabilitation, and six-month and one-year follow-ups. After rehabilitation gait had improved, the patient had more arm movement, more pelvic shift, less hip rotation during swing phase on the prosthetic side, and absence of vaulting on the sound side. Isometric hip abductor strength was 15% higher on the sound side and 16% higher on the prosthetic side, and walking distance increased from 200 m to 1500 m. At the six-month follow-up, the patient had lower back complications and reduced hip abductor strength and walking distance. At one-year follow-up, walking distance had recovered to 1000 m and gait pattern had improved again, with yielding and absence of terminal impact on the prosthetic side. The described rehabilitation program may be an effective method of improving gait in patients with an EEFP even after long-term socket usage.

[Endo-exo prostheses : Osseointegrated percutaneously channeled implants for rehabilitation after limb amputation].

In 1999 the first endo-exo femoral prosthesis (EEFP) was implanted in Germany in a patient who had suffered a traumatic above-knee amputation. This procedure involves a skeletally anchored exoprosthetic device that is inserted into the residual femur. The distal part of the implant protrudes transcutaneously and allows attachment to a prosthetic limb which provides direct force transmission to the external prosthetic components. The technique originated from dental implantology and helps to avoid possible problems resulting from treatment of amputated limbs using socket prostheses. In the meantime, durability times of over 10 years have now helped to invalidate the initially well-founded reservations held against the procedure. What advantages can be achieved by osseointegrated and percutaneously channeled prostheses and which problems had to be overcome for treatment. Critical evaluation of data from patients operated on in Lübeck, Germany from January 2003 to December 2014. With osseointegrated and percutaneously channeled prostheses permanent durability times can be achieved. Infection-associated soft tissue problems at the site of skin protrusion (stoma) can be successfully prevented. The creation of this so-called stoma means acceptance of a possible bacterial portal of entry into the body. Patient satisfaction has so far been high, postoperative rehabilitation is simplified and the technique could possibly lower the costs of medical treatment. Endo-exo prostheses have proved to be successful for more than 15 years. A critical appraisal of the indications as well as a close cooperation between the surgeon, orthopedic technician and the associated rehabilitation facilities with the patient are the basis for the long-term success of this relatively new treatment approach.

Cystinosis, the most frequent cause of inborn Fanconi syndrome, is characterized by the lysosomal cystine accumulation, caused by mutations in the CTNS gene. To elucidate the pathogenesis of cystinosis, we cultured proximal tubular cells from urine of cystinotic patients (n = 9) and healthy controls (n = 9), followed by immortalization with human papilloma virus (HPV E6/E7). Obtained cell lines displayed basolateral polarization, alkaline phosphatase activity, and presence of aminopeptidase N (CD-13) and megalin, confirming their proximal tubular origin. Cystinotic cell lines exhibited elevated cystine levels (0.86 +/- 0.95 nmol/mg versus 0.09 +/- 0.01 nmol/mg protein in controls, p = 0.03). Oxidized glutathione was elevated in cystinotic cells (1.16 +/- 0.83 nmol/mg versus 0.29 +/- 0.18 nmol/mg protein, p = 0.04), while total glutathione, free cysteine, and ATP contents were normal in these cells. In conclusion, elevated oxidized glutathione in cystinotic proximal tubular epithelial cell lines suggests increased oxidative stress, which may contribute to tubular dysfunction in cystinosis.

Ultimate Drivers and Proximate Correlates of Polyandry in Predatory Mites.

Peter Schausberger

Full Text Available Polyandry is more widespread than anticipated from Bateman's principle but its ultimate (evolutionary causes and proximate (mechanistic correlates are more difficult to pinpoint than those of polygyny. Here, we combined mating experiments, quantification of reproductive traits and microsatellite genotyping to determine the fitness implications of polyandry in two predatory mite species, where males are highly polygynous (up to 45 fertilized females during life, whereas females range from monandry to various polyandry levels. The medium-level polyandrous (up to eight male mates possible Neoseiulus californicus received clear direct and indirect benefits: multiply mated females produced more offspring with higher survival chances over longer times than singly mated females. In contrast, singly and multiply mated females of the low-level polyandrous (commonly two male mates at maximum Phytoseiulus persimilis produced similar numbers of offspring having similar survival chances. In both species, multiple mating resulted in mixed offspring paternities, opening the chance for indirect fitness benefits such as enhanced genetic compatibility, complementarity and/or variability. However, the female re-mating likelihood and the paternity chance of non-first male mates were lower in P. persimilis than in N. californicus. Regarding proximate factors, in both species first mating duration and female re-mating likelihood were negatively correlated. Based on occasional fertilization failure of first male mates in P. persimilis, and mixed offspring paternities in both species, we argue that fertilization assurance and the chance to gain indirect fitness benefits are the ultimate drivers of polyandry in P. persimilis, whereas those of N. californicus are higher offspring numbers coupled with enhanced offspring viability and possibly other indirect fitness benefits. Overall, the adaptive significance and proximate events well reflected the polyandry levels. Our

Polyandry is more widespread than anticipated from Bateman's principle but its ultimate (evolutionary) causes and proximate (mechanistic) correlates are more difficult to pinpoint than those of polygyny. Here, we combined mating experiments, quantification of reproductive traits and microsatellite genotyping to determine the fitness implications of polyandry in two predatory mite species, where males are highly polygynous (up to 45 fertilized females during life), whereas females range from monandry to various polyandry levels. The medium-level polyandrous (up to eight male mates possible) Neoseiulus californicus received clear direct and indirect benefits: multiply mated females produced more offspring with higher survival chances over longer times than singly mated females. In contrast, singly and multiply mated females of the low-level polyandrous (commonly two male mates at maximum) Phytoseiulus persimilis produced similar numbers of offspring having similar survival chances. In both species, multiple mating resulted in mixed offspring paternities, opening the chance for indirect fitness benefits such as enhanced genetic compatibility, complementarity and/or variability. However, the female re-mating likelihood and the paternity chance of non-first male mates were lower in P. persimilis than in N. californicus. Regarding proximate factors, in both species first mating duration and female re-mating likelihood were negatively correlated. Based on occasional fertilization failure of first male mates in P. persimilis, and mixed offspring paternities in both species, we argue that fertilization assurance and the chance to gain indirect fitness benefits are the ultimate drivers of polyandry in P. persimilis, whereas those of N. californicus are higher offspring numbers coupled with enhanced offspring viability and possibly other indirect fitness benefits. Overall, the adaptive significance and proximate events well reflected the polyandry levels. Our study provides a

ProxImaL: efficient image optimization using proximal algorithms

KAUST Repository

Heide, Felix

2016-07-11

Computational photography systems are becoming increasingly diverse, while computational resources-for example on mobile platforms-are rapidly increasing. As diverse as these camera systems may be, slightly different variants of the underlying image processing tasks, such as demosaicking, deconvolution, denoising, inpainting, image fusion, and alignment, are shared between all of these systems. Formal optimization methods have recently been demonstrated to achieve state-of-the-art quality for many of these applications. Unfortunately, different combinations of natural image priors and optimization algorithms may be optimal for different problems, and implementing and testing each combination is currently a time-consuming and error-prone process. ProxImaL is a domain-specific language and compiler for image optimization problems that makes it easy to experiment with different problem formulations and algorithm choices. The language uses proximal operators as the fundamental building blocks of a variety of linear and nonlinear image formation models and cost functions, advanced image priors, and noise models. The compiler intelligently chooses the best way to translate a problem formulation and choice of optimization algorithm into an efficient solver implementation. In applications to the image processing pipeline, deconvolution in the presence of Poisson-distributed shot noise, and burst denoising, we show that a few lines of ProxImaL code can generate highly efficient solvers that achieve state-of-the-art results. We also show applications to the nonlinear and nonconvex problem of phase retrieval.

Gait adaptability, including the ability to avoid obstacles and to take visually guided steps, is essential for safe movement through a cluttered world. This aspect of walking ability is important for regaining independent mobility but is difficult to assess in clinical practice. The objective of this study was to investigate the validity of an instrumented treadmill with obstacles and stepping targets projected on the belt's surface for assessing prosthetic gait adaptability. This was an observational study. A control group of people who were able bodied (n=12) and groups of people with transtibial (n=12) and transfemoral (n=12) amputations participated. Participants walked at a self-selected speed on an instrumented treadmill with projected visual obstacles and stepping targets. Gait adaptability was evaluated in terms of anticipatory and reactive obstacle avoidance performance (for obstacles presented 4 steps and 1 step ahead, respectively) and accuracy of stepping on regular and irregular patterns of stepping targets. In addition, several clinical tests were administered, including timed walking tests and reports of incidence of falls and fear of falling. Obstacle avoidance performance and stepping accuracy were significantly lower in the groups with amputations than in the control group. Anticipatory obstacle avoidance performance was moderately correlated with timed walking test scores. Reactive obstacle avoidance performance and stepping accuracy performance were not related to timed walking tests. Gait adaptability scores did not differ in groups stratified by incidence of falls or fear of falling. Because gait adaptability was affected by walking speed, differences in self-selected walking speed may have diminished differences in gait adaptability between groups. Gait adaptability can be validly assessed by use of an instrumented treadmill with a projected visual context. When walking speed is taken into account, this assessment provides unique

Full Text Available The theatricality of urban encounters is above all a theatricality of distances which allow for the encounter. The absolute “strangeness” of the crowd (Simmel 1997: 74 expressed, in its purest form, in the absolute proximity of a crowded subway train, does not generally allow for any movements of approach, but only for nervous hostile reactions and submissive hypnotic gestures. Neither forced intersections in the course of pedestrians or vehicles, nor the instantaneous crossing of distances by the technology of live broadcasting and remote control give birth to places of encounter. In the forced proximity of the metropolitan crowd which haunted the city of the 19th and 20th century, as well as in the forced proximity of the tele-presence which haunts the dystopic prospect of the future “omnipolis” (Virilio 1997: 74, the necessary distance, which is the stage of an encounter between different instances of otherness, is dissipated.

2002-01-01

To determine whether subtraction images utilizing contrast media can improve the diagnostic performance of proximal caries diagnosis compared to conventional periapical radiographic images. Thirty-six teeth with 57 proximal surfaces were radiographied using a size no.2 RVG-ui sensor (Trophy Radiology, Marne-la-Vallee, France). The teeth immersed in water-soluble contrast media and subtraction images were taken. Each tooth was then sectioned for histologic examination. The digital radiographic images and subtraction images were examined and interpreted by three dentists for proximal caries. The results of the proximal caries diagnosis were then verified with the results of the histologic examination. The proximal caries sensitivity using digital subtraction radiography was significantly higher than simply examining a single digital radiograph. The sensitivity of the proximal dentinal carious lesion when analyzed with the subtraction radiograph and the radiograph together was higher than with the subtraction radiograph or the radiograph alone. The use of subtraction radiography with contrast media may be useful for detecting proximal dentinal carious lesions.

Risk factors for hallux valgus recurrence include postoperative round-shaped lateral edge of the first metatarsal head and postoperative incomplete reduction of the sesamoids. To prevent the occurrence of such conditions, we developed a proximal supination osteotomy of the first metatarsal. Our aim was to describe this novel technique and report the outcomes in this report. Sixty-six patients (83 feet) underwent a distal soft tissue procedure combined with a proximal supination osteotomy. After the proximal crescentic osteotomy, the proximal fragment was pushed medially, and the distal fragment was abducted, and then the distal fragment of the first metatarsal was manually supinated. Outcomes were assessed using the American Orthopaedic Foot & Ankle Society (AOFAS) score and radiographic examinations. The average follow-up duration was 34 (range, 25 to 52) months. The mean AOFAS score improved significantly from 58.0 points preoperatively to 93.8 points postoperatively (P hallux valgus and intermetatarsal angle decreased significantly from 38.6 and 18.0 degrees preoperatively to 11.0 and 7.9 degrees postoperatively, respectively (both, P hallux valgus, defined as a hallux valgus angle ≥ 25 degrees. The rates of occurrence of a positive round sign and incomplete reduction of the sesamoids significantly decreased postoperatively, which may have contributed to the low hallux valgus recurrence rates. We conclude that a proximal supination osteotomy was an effective procedure for correction of hallux valgus and can achieve a low rate of hallux valgus recurrence.

Objective : The treatment of diabetic hindfoot ulcers is a challenging problem. In addition to serial surgical debridements, hyperbaric oxygen therapy and local wound care play important roles in the surgeon's armamentarium, for both superficial infection and gangrene of the soft tissue, often complicated by osteomyelitis of the calcaneus. The purpose of this study was to evaluate the results of an aggressive approach from diagnosis to treatment of calcaneal osteomyelitis in foot-threatening diabetic calcaneal ulcers. Methods : The study included 23 patients with diabetic hindfoot ulcers who were treated with radical excision of the necrotic tissue and application of circular external fixation. The treatment protocol was a combination of magnetic resonance imaging (MRI)-guided debridement of the necrotic tissues and application of an Ilizarov external fixator in plantarflexion to decrease the soft-tissue defect. Primary outcome measures were total cure of infection and obvious healing of the osteomyelitis at 12 weeks determined by MRI, and clinical cure through objective assessment of the appearance of the wound. Results : The wounds healed in 18 of the 23 patients (78%), partial recovery occurred and subsequent flap operation was performed in three patients (13%), and below-the-knee amputation was performed in two patients (9%). Conclusions : This surgical protocol is effective in ameliorating diabetic hindfoot ulcers with concomitant calcaneal osteomyelitis, and satisfactorily reduces the need for amputation.

Full Text Available In 2010, Bounkhel et al. introduced new proximal concepts (analytic proximal subdifferential, geometric proximal subdifferential, and proximal normal cone in reflexive smooth Banach spaces. They proved, in p-uniformly convex and q-uniformly smooth Banach spaces, the density theorem for the new concepts of proximal subdifferential and various important properties for both proximal subdifferential concepts and the proximal normal cone concept. In this paper, we establish calculus rules (fuzzy sum rule and chain rule for both proximal subdifferentials and we prove the Bishop-Phelps theorem for the proximal normal cone. The limiting concept for both proximal subdifferentials and for the proximal normal cone is defined and studied. We prove that both limiting constructions coincide with the Mordukhovich constructions under some assumptions on the space. Applications to nonconvex minimisation problems and nonconvex variational inequalities are established.

Proximal Humerus Fractures: Evaluation and Management in the Elderly Patient

Grawe, Brian

2018-01-01

Introduction: Proximal humerus fractures are common in the elderly. The evaluation and management of these injuries is often controversial. The purpose of this study is to review recent evidence and provide updated recommendations for treating proximal humerus fractures in the elderly. Methods: A literature review of peer-reviewed publications related to the evaluation and management of proximal humerus fractures in the elderly was performed. There was a focus on randomized controlled trials and systematic reviews published within the last 5 years. Results: The incidence of proximal humerus fractures is increasing. It is a common osteoporotic fracture. Bone density is a predictor of reduction quality and can be readily assessed with anteroposterior views of the shoulder. Social independence is a predictor of outcome, whereas age is not. Many fractures are minimally displaced and respond acceptably to nonoperative management. Displaced and severe fractures are most frequently treated operatively with intramedullary nails, locking plates, percutaneous techniques, or arthroplasty. Discussion: Evidence from randomized controlled trials and systematic reviews is insufficient to recommend a treatment; however, most techniques have acceptable or good outcomes. Evaluation should include an assessment of the patient’s bone quality, social independence, and surgical risk factors. With internal fixation, special attention should be paid to medial comminution, varus angulation, and restoration of the calcar. With arthroplasty, attention should be paid to anatomic restoration of the tuberosities and proper placement of the prosthesis. Conclusion: A majority of minimally displaced fractures can be treated conservatively with early physical therapy. Treatment for displaced fractures should consider the patient’s level of independence, bone quality, and surgical risk factors. Fixation with percutaneous techniques, intramedullary nails, locking plates, and arthroplasty are all

Full Text Available We glance at recent advances to the general theory of maximal (set-valued monotone mappings and their role demonstrated to examine the convex programming and closely related field of nonlinear variational inequalities. We focus mostly on applications of the super-relaxed ( -proximal point algorithm to the context of solving a class of nonlinear variational inclusion problems, based on the notion of maximal ( -monotonicity. Investigations highlighted in this communication are greatly influenced by the celebrated work of Rockafellar (1976, while others have played a significant part as well in generalizing the proximal point algorithm considered by Rockafellar (1976 to the case of the relaxed proximal point algorithm by Eckstein and Bertsekas (1992. Even for the linear convergence analysis for the overrelaxed (or super-relaxed ( -proximal point algorithm, the fundamental model for Rockafellar's case does the job. Furthermore, we attempt to explore possibilities of generalizing the Yosida regularization/approximation in light of maximal ( -monotonicity, and then applying to first-order evolution equations/inclusions.

Varus failure is one of the most common failure modes following surgical treatment of proximal humeral fractures. Straight antegrade nails (SAN) theoretically provide increased stability by anchoring to the densest zone of the proximal humerus (subchondral zone) with the end of the nail. The aim of this study was to biomechanically investigate the characteristics of this "proximal anchoring point" (PAP). We hypothesized that the PAP would improve stability compared to the same construct without the PAP. Straight antegrade humeral nailing was performed in 20 matched pairs of human cadaveric humeri for a simulated unstable two-part fracture. Biomechanical testing, with stepwise increasing cyclic axial loading (50-N increments each 100 cycles) at an angle of 20° abduction revealed significantly higher median loads to failure for SAN constructs with the PAP (median, 450 N; range, 200-1.000 N) compared to those without the PAP (median, 325 N; range, 100-500 N; p = 0.009). SAN constructs with press-fit proximal extensions (endcaps) showed similar median loads to failure (median, 400 N; range, 200-650 N), when compared to the undersized, commercially available SAN endcaps (median, 450 N; range, 200-600 N; p = 0.240). The PAP provided significantly increased stability in SAN constructs compared to the same setup without this additional proximal anchoring point. Varus-displacing forces to the humeral head were superiorly reduced in this setting. This study provides biomechanical evidence for the "proximal anchoring point's" rationale. Straight antegrade humeral nailing may be beneficial for patients undergoing surgical treatment for unstable proximal humeral fractures to decrease secondary varus displacement and thus potentially reduce revision rates.

Politics, proximity and the pipeline: Mapping public attitudes toward Keystone XL

Gravelle, Timothy B.; Lachapelle, Erick

2015-01-01

The politics of oil pipelines have become increasingly salient in American politics in recent years. In particular, debates about economic benefits, energy security and environmental impact have been provoked by the proposed Keystone XL pipeline expansion intended to take bitumen from northern Alberta in Canada to refineries on the Gulf Coast in Texas. Drawing on data from recent surveys conducted by the Pew Research Center, this article asks a series of questions. What levels of support for (and opposition to) the pipeline exist among the American public? What are the roles of political factors (such as party identification and ideology), economic attitudes, environmental attitudes and proximity to the proposed pipeline route in shaping attitudes toward the pipeline? And how do political factors and proximity to the pipeline interact? We find that partisanship and ideology drive attitudes toward the Keystone XL pipeline, and that the effect of ideology is attenuated by proximity to the proposed route. The policy implications of these findings for energy infrastructure siting controversies are discussed. -- Highlights: •Americans are divided on the Keystone XL energy pipeline. •Attitudes toward Keystone XL are driven by political party identification and ideology. •Attitudes toward the pipeline are also shaped by attitudes toward the economy and global warming. •The effect of proximity on attitudes toward Keystone XL is non-linear. •Spatial proximity to the pipeline attenuates the effect of ideology

Innervation of the renal proximal convoluted tubule of the rat

Experimental data suggest the proximal tubule as a major site of neurogenic influence on tubular function. The functional and anatomical axial heterogeneity of the proximal tubule prompted this study of the distribution of innervation sites along the early, mid, and late proximal convoluted tubule (PCT) of the rat. Serial section autoradiograms, with tritiated norepinephrine serving as a marker for monoaminergic nerves, were used in this study. Freehand clay models and graphic reconstructions of proximal tubules permitted a rough estimation of the location of the innervation sites along the PCT. In the subcapsular nephrons, the early PCT (first third) was devoid of innervation sites with most of the innervation occurring in the mid (middle third) and in the late (last third) PCT. Innervation sites were found in the early PCT in nephrons located deeper in the cortex. In juxtamedullary nephrons, innervation sites could be observed on the PCT as it left the glomerulus. This gradient of PCT innervation can be explained by the different tubulovascular relationships of nephrons at different levels of the cortex. The absence of innervation sites in the early PCT of subcapsular nephrons suggests that any influence of the renal nerves on the early PCT might be due to an effect of neurotransmitter released from renal nerves reaching the early PCT via the interstitium and/or capillaries

OBJECTIVE Proximal junctional kyphosis (PJK) is a well-recognized, yet incompletely defined, complication of adult spinal deformity surgery. There is no standardized definition for PJK, but most studies describe PJK as an increase in the proximal junctional angle (PJA) of greater than 10°-20°. Ligament augmentation is a novel strategy for PJK reduction that provides strength to the upper instrumented vertebra (UIV) and adjacent segments while also reducing junctional stress at those levels. METHODS In this study, ligament augmentation was used in a consecutive series of adult spinal deformity patients at a single institution. Patient demographics, including age; sex; indication for surgery; revision surgery; surgical approach; and use of 3-column osteotomies, vertebroplasty, or hook fixation at the UIV, were collected. The PJA was measured preoperatively and at last follow-up using 36-inch radiographs. Data on change in PJA and need for revision surgery were collected. Univariate and multivariate analyses were performed to identify factors associated with change in PJA and proximal junctional failure (PJF), defined as PJK requiring surgical correction. RESULTS A total of 200 consecutive patients were included: 100 patients before implementation of ligament augmentation and 100 patients after implementation of this technique. The mean age of the ligament augmentation cohort was 66 years, and 67% of patients were women. Over half of these cases (51%) were revision surgeries, with 38% involving a combined anterior or lateral and posterior approach. The mean change in PJA was 6° in the ligament augmentation group compared with 14° in the control group (p historical cohort, ligament augmentation is associated with a significant decrease in PJK and PJF. These data support the implementation of ligament augmentation in surgery for adult spinal deformity, particularly in patients with a high risk of developing PJK and PJF.

Proximal Tubular Injury in Medullary Rays Is an Early Sign of Acute Tacrolimus Nephrotoxicity

Full Text Available Tacrolimus (FK506 is one of the principal immunosuppressive agents used after solid organ transplantations to prevent allograft rejection. Chronic renal injury induced by tacrolimus is characterized by linear fibrosis in the medullary rays; however, the early morphologic findings of acute tacrolimus nephrotoxicity are not well characterized. Kidney injury molecule-1 (KIM-1 is a specific injury biomarker that has been proven to be useful in the diagnosis of mild to severe acute tubular injury on renal biopsies. This study was motivated by a patient with acute kidney injury associated with elevated serum tacrolimus levels in whom KIM-1 staining was present only in proximal tubules located in the medullary rays in the setting of otherwise normal light, immunofluorescent, and electron microscopy. We subsequently evaluated KIM-1 expression in 45 protocol and 39 indicated renal transplant biopsies to determine whether higher serum levels of tacrolimus were associated with acute segment specific injury to the proximal tubule, as reflected by KIM-1 staining in the proximal tubules of the cortical medullary rays. The data suggest that tacrolimus toxicity preferentially affects proximal tubules in medullary rays and that this targeted injury is a precursor lesion for the linear fibrosis seen in chronic tacrolimus toxicity.

The proximity effect is a phenomenon where an ordered state leaks from a material into an adjacent one over some finite distance, ξ. For superconductors, this distance is ~ the coherence length. Nevertheless much longer-range, ``giant'' proximity effects have been observed in cuprate junctions. This surprising effect can be understood as a consequence of critical opalescence. Since this occurs near all second order phase transitions, giant proximity effects should be very general and, in particular, they should be present in magnetic systems. The ferromagnetic proximity effect has the advantage that its order parameter (magnetization) can be observed directly. We investigate the above phenomenon in Co/EuS bilayer films, where both materials undergo ferromagnetic transitions but at rather different temperatures (bulk TC of 1400K for Co and 16.6K for EuS). A dramatic increase in the range of the proximity effect is expected near the TC of EuS. We present the results of our measurements of the magnetization profiles as a function of temperature, carried out using the complementary techniques of low energy muon rotation and polarized neutron reflectivity.

Many individuals with lower limb loss report concern with walking ability after completing structured traditional rehabilitation. The purpose of this study was to explore the impact of a supervised community-based exercise program on balance, balance confidence, and gait in individuals with lower limb amputation. Repeated measures. The supervised exercise program was offered biweekly for 6 weeks. The GAITRite System by CIR Systems, Inc., the Figure-of-8 Walk Test, and Activity-specific Balance Confidence Scale were used to measure clinical outcomes pre- and post-intervention. In total, 16 participants with lower limb amputation (mean age: 50.8 years) completed the study. A multivariate, repeated measures analysis of variance indicated a statistically significant effect of training across six clinical outcome measures ( F(6, 10) = 4.514, p = .018). Moderate effect sizes were found for the Figure-of-8 Walk Test ( η 2 = .586), Activity-specific Balance Confidence Scale ( η 2 = .504), and gait velocity at comfortable walking speed ( η 2 = .574). The average increase in gait speed was clinically meaningful at .14 m/s. The supervised community-based exercise program implemented in this study was designed to address specific functional needs for individuals with lower limb loss. Each participant experienced clinically meaningful improvements in balance, balance confidence, and walking ability. Clinical relevance The provision of a supervised community-based exercise program, after traditional rehabilitation, provides opportunity to offer a continuum of care that may enhance prosthetic functional ability and active participation in the community for individuals with lower limb amputation.

Studies have indicated that many initial proximal caries lesions progress and are eventually restored even if the patients have been under comprehensive preventive programmes. The objectives of the study were (1) to describe the 1996-year baseline caries status of male Danish conscripts and (2......) to assess their early proximal lesions 6-year behaviour. In 1996, all 20-year-old conscripts at Central Barrack Birkerød (n = 115) went through an oral examination, including visual surface-level fillings' recording and a radiographic examination with bitewing radiographs that assessed the proximal......-surface caries and restoration patterns. After 6 years, the behaviour of proximal lesions was studied in 73 of these subjects, and oral health habits were assessed through a questionnaire. Mean number of filled surfaces was 7.5, of which 23% were posterior proximal. Radiographically, the mean number of proximal...

Intraosseous needle insertion and infusion is considered an easy and reliable method of achieving a vascular access in acute circulatory collapse where other methods have not been successful within reasonable time. Complications are considered few but may be serious. We present a case of a newborn...... girl, where intraosseous cannulation of the tibia was lifesaving. Despite following most standard recommendations, the treatment resulted in transtibial amputation due to necrosis. We suspect that the necrosis was a consequence of extravasation of tissue-toxic calcium infusion....

Diabetic foot ulcer is an important entity which in many cases is the first serious complication in diabetes. Although a plantar forefoot location is common, there are few studies on larger cohorts and in such studies there is often a combination of various types of ulcer and ulcer locations. The purpose of this study is to discern the outcome of plantar forefoot ulcers and their specific characteristics in a large cohort. All patients (n = 770), presenting with a plantar forefoot ulcer at a multidisciplinary diabetes foot clinic from January 1, 1983 to December 31, 2012 were considered for the study. Seven hundred one patients (median age 67 [22-95]) fulfilled the inclusion criteria and were followed according to a preset protocol until final outcome (healing or death). Severe peripheral vascular disease was present in 26% of the patients and 14% had evidence of deep infection upon arrival at the foot clinic. Fifty-five percent (385/701) of the patients healed without foot surgery, 25% (173/701) healed after major debridement, 9% (60/701) healed after minor or major amputation and 12% (83/701) died unhealed. Median healing time was 17 weeks. An ulcer classified as Wagner grade 1 or 2 at inclusion and independent living were factors associated with a higher healing rate. Seventy-nine percent of 701 patients with diabetes and a plantar forefoot ulcer treated at a multidisciplinary diabetes foot clinic healed without amputation. For one third some form of foot surgery was needed to achieve healing. © 2015 by the Wound Healing Society.

The effect of various anthropogenic sources of noise (e.g. sonar, seismic surveys) on the behaviour of marine mammals is sometimes quantified as a dose-response relationship, where the probability of an animal behaviourally 'responding' (e.g. avoiding the source) increases with 'dose' (or received level of noise). To do this, however, requires a definition of a 'significant' response (avoidance), which can be difficult to quantify. There is also the potential that the animal 'avoids' not only the source of noise but also the vessel operating the source, complicating the relationship. The proximity of the source is an important variable to consider in the response, yet difficult to account for given that received level and proximity are highly correlated. This study used the behavioural response of humpback whales to noise from two different air gun arrays (20 and 140 cubic inch air gun array) to determine whether a dose-response relationship existed. To do this, a measure of avoidance of the source was developed, and the magnitude (rather than probability) of this response was tested against dose. The proximity to the source, and the vessel itself, was included within the one-analysis model. Humpback whales were more likely to avoid the air gun arrays (but not the controls) within 3 km of the source at levels over 140 re. 1 µPa 2  s -1 , meaning that both the proximity and the received level were important factors and the relationship between dose (received level) and response is not a simple one. © 2017.

Quantum Proximity Resonances

International Nuclear Information System (INIS)

Heller, E.J.

1996-01-01

It is well known that at long wavelengths λ an s-wave scatterer can have a scattering cross section σ on the order of λ 2 , much larger than its physical size, as measured by the range of its potential. Very interesting phenomena can arise when two or more identical scatterers are placed close together, well within one wavelength. We show that, for a pair of identical scatterers, an extremely narrow p-wave open-quote open-quote proximity close-quote close-quote resonance develops from a broader s-wave resonance of the individual scatterers. A new s-wave resonance of the pair also appears. The relation of these proximity resonances (so called because they appear when the scatterers are close together) to the Thomas and Efimov effects is discussed. copyright 1996 The American Physical Society

The management of displaced 2- and 3-part fractures of the proximal humerus is controversial, both in younger and in elderly patients. The purpose of this paper is to evaluate the functional results of the Contours Proximal Humerus Plate (OrthofixR, Bussolengo,Verona, Italy), for the treatment of displaced 2- and 3-part fractures of the proximal humerus. We retrospectively reviewed 55 patients with proximal humerus fractures, who underwent osteosynthesis with Contours Proximal Humerus Plate from December 2011 to March 2015. We had 21 patients with 2-part fractures and with an average age of 67.1 years and 34 patients with 3-part fractures, with average age of 63.6 years. The average union time was 3 months. The mean Constant score was 67 for 2-part fracture group and 64.9 for 3-part fracture group. The difference was not statistically significant (p = 0.18). The overall complication rate was 14.5 %. Six patients underwent additional surgery (10.9%). The most frequent major complication was secondary loss of reduction following varus collapse of the fracture (2 cases). In these patients, there was loss of medial hinge integrity due to impaction and osteoporosis. The placement of the main locking screw in the calcar area to provide inferomedial support is the rational of the Contours Proximal Humerus Plate. Osteosynthesis with Contours Proximal Humerus Plate is a safe system for treating displaced 2- and 3-part fractures of the proximal humerus, with good functional results and complication rates comparable to those reported in the literature.

Regeneration of soft tissues is promoted by MMP1 treatment after digit amputation in mice.

Full Text Available The ratio of matrix metalloproteinases (MMPs to the tissue inhibitors of metalloproteinases (TIMPs in wounded tissues strictly control the protease activity of MMPs, and therefore regulate the progress of wound closure, tissue regeneration and scar formation. Some amphibians (i.e. axolotl/newt demonstrate complete regeneration of missing or wounded digits and even limbs; MMPs play a critical role during amphibian regeneration. Conversely, mammalian wound healing re-establishes tissue integrity, but at the expense of scar tissue formation. The differences between amphibian regeneration and mammalian wound healing can be attributed to the greater ratio of MMPs to TIMPs in amphibian tissue. Previous studies have demonstrated the ability of MMP1 to effectively promote skeletal muscle regeneration by favoring extracellular matrix (ECM remodeling to enhance cell proliferation and migration. In this study, MMP1 was administered to the digits amputated at the mid-second phalanx of adult mice to observe its effect on digit regeneration. Results indicated that the regeneration of soft tissue and the rate of wound closure were significantly improved by MMP1 administration, but the elongation of the skeletal tissue was insignificantly affected. During digit regeneration, more mutipotent progenitor cells, capillary vasculature and neuromuscular-related tissues were observed in MMP1 treated tissues; moreover, there was less fibrotic tissue formed in treated digits. In summary, MMP1 was found to be effective in promoting wound healing in amputated digits of adult mice.

Proximal hamstring tendinosis and partial hamstring origin ruptures are painful conditions of the proximal thigh and hip that may occur in the acute, chronic, or acute on chronic setting. Few publications exist related to their diagnosis and management. This systematic review discusses the incidence, treatment, and prognosis of proximal hamstring tendinosis and partial hamstring ruptures. Conservative treatment measures include nonsteroidal anti-inflammatory drugs, physical therapy, rest, and ice. If these measures fail, platelet-rich plasma or shockwave therapy may be considered. When refractory to conservative management, these injuries may be treated with surgical debridement and hamstring reattachment. [Orthopedics. 2017; 40(4):e574-e582.].

Paul Wittgenstein's right arm and his phantom: the saga of a famous concert pianist and his amputation.

Reports of postamputation pain and problems linked to phantom limbs have increased in recent years, particularly in relation to war-related amputations. These problems are still poorly understood and are considered rather mysterious, and they are difficult to treat. In addition, they may shed light on brain physiology and neuropsychology. Functional neuroimaging techniques now enable us to better understand their pathophysiology and to consider new rehabilitation techniques. Several artists have suffered from postamputation complications and this has influenced not only their personal life but also their artistic work. Paul Wittgenstein (1887-1961), a pianist whose right arm was amputated during the First World War, became a famous left-handed concert performer. His case provides insight into Post-World War I musical and political history. More specifically, the impact on the artistic life of this pianist illustrates various postamputation complications, such as phantom limb, stump pain, and especially moving phantom. The phantom movements of his right hand helped him develop the dexterity of his left hand. Wittgenstein played piano works that were written especially for him (the most famous being Ravel's Concerto for the Left Hand) and composed some of his own. Additionally, several famous composers had previously written for the left hand. © 2015 Elsevier B.V. All rights reserved.

A growing number of clinical trials and case reports support qualitative claims that use of an elevated vacuum suspension (EVS) prosthesis improves residual-limb health on the basis of self-reported questionnaires, clinical outcomes scales, and wound closure studies. Here, we report first efforts to quantitatively assess residual-limb circulation in response to EVS. Residual-limb skin health and perfusion of people with lower-limb amputation (N = 10) were assessed during a randomized crossover study comparing EVS with nonelevated vacuum suspension (control) over a 32 wk period using noninvasive probes (transepidermal water loss, laser speckle imaging, transcutaneous oxygen measurement) and functional hyperspectral imaging approaches. Regardless of the suspension system, prosthesis donning decreased perfusion in the residual limb under resting conditions. After 16 wk of use, EVS improved residual-limb oxygenation during treadmill walking. Likewise, prosthesis-induced reactive hyperemia was attenuated with EVS following 16 wk of use. Skin barrier function was preserved with EVS but disrupted after control socket use. Taken together, outcomes suggest chronic EVS use improves perfusion and preserves skin barrier function in people with lower-limb amputation.

The intermediate effect of geographic proximity on intergenerational support: A comparison of France and Bulgaria

Full Text Available BACKGROUND The geographic proximity of parents and adult children is a key element of intergenerational solidarity. Many studies have identified geographical distance as an important determinant of intergenerational support: living nearby increases the amount of mutual support provided. It can, however, also be regarded as a dimension of intergenerational solidarity: the current degree of proximity is the result of past migration decisions made by both generations, in which present and future care demands potentially played a key role. OBJECTIVE We take this endogenous nature of geographical distance into account by examining theindirect effect of the determinants of the actual level of support through geographical distance. Both upward support (personal care provided to mother and downward support (help with childcare received from mother are considered. METHODS Path analyses are performed on data from the Generations and Gender Survey for France and Bulgaria using a general latent-variable modelling framework in multiple-group models. RESULTS In addition to strongly affecting the level of support provided and received, geographical distance itself is affected by several individual and family-related variables, which in turn have an indirect effect on the level of intergenerational support. The results suggest that proximity can be used as an adaptive strategy: e.g., working adult children in France receive more help with childcare because of their greater proximity to their mothers. Having a greater care need may have triggered this choice of residence. Similarly, single parents with no partner to rely on tend to live closer to their mothers, and therefore receive more help. CONCLUSIONS Geographic proximity can be considered a latent form of solidarity that functions as a mediator between background factors and manifest, functional solidarity.
