    Background: Whole-body magnetic resonance angiography (WBMRA) permits noninvasive vascular assessment, which can be utilized in epidemiological studies. Purpose: To assess the relation between a low ankle brachial index (ABI) and high-grade stenoses in the pelvic and leg arteries in the elderly. Material and Methods: WBMRA was performed in a population sample of 306 subjects aged 70 years. The arteries below the aortic bifurcation were graded after the most severe stenosis according to one of three grades: 0-49% stenosis, 50-99% stenosis, or occlusion. ABI was calculated for each side. Results: There were assessable WBMRA and ABI examinations in 268 (right side), 265 (left side), and 258 cases (both sides). At least one >=50% stenosis was found in 19% (right side), 23% (left side), and 28% (on at least one side) of the cases. The corresponding prevalences for ABI <0.9 were 4.5%, 4.2%, and 6.6%. An ABI cut-off value of 0.9 resulted in a sensitivity, specificity, and positive and negative predictive value of 20%, 99%, 83%, and 84% on the right side, and 15%, 99%, 82%, and 80% on the left side, respectively, for the presence of a >= 50% stenosis in the pelvic or leg arteries. Conclusion: An ABI <0.9 underestimates the prevalence of peripheral arterial occlusive disease in the general elderly population

    Full Text Available Abstract Background Patients infected with HIV have an increased risk for accelerated atherosclerosis. Elevated levels of osteoprotegerin, an inflammatory cytokine receptor, have been associated with a high incidence of cardiovascular disease (including peripheral arterial disease, or PAD, acute coronary syndrome, and cardiovascular mortality. The objective of this study was to determine whether PAD is prevalent in an HIV-infected population, and to identify an association with HIV-specific and traditional cardiovascular risk factors, as well as levels of osteoprotegerin. Methods One hundred and two patients infected with HIV were recruited in a cross-sectional study. To identify the prevalence of PAD, ankle-brachial indices (ABIs were measured. Four standard ABI categories were utilized: ≤ 0.90 (definite PAD; 0.91-0.99 (borderline; 1.00-1.30 (normal; and >1.30 (high. Medical history and laboratory measurements were obtained to determine possible risk factors associated with PAD in HIV-infected patients. Results The prevalence of PAD (ABI ≤ 0.90 in a young HIV-infected population (mean age: 48 years was 11%. Traditional cardiovascular risk factors, including advanced age and previous cardiovascular history, as well as elevated C-reactive protein levels, were associated with PAD. Compared with patients with normal ABIs, patients with high ABIs had significantly elevated levels of osteoprotegerin [1428.9 (713.1 pg/ml vs. 3088.6 (3565.9 pg/ml, respectively, p = 0.03]. Conclusions There is a high prevalence of PAD in young HIV-infected patients. A number of traditional cardiovascular risk factors and increased osteoprotegerin concentrations are associated with abnormal ABIs. Thus, early screening and aggressive medical management for PAD may be warranted in HIV-infected patients.

    2009-04-01

    Full Text Available Abstract Prognosis for patients with the human immunodeficiency virus (HIV has improved with the introduction of highly active antiretroviral therapy (HAART. Evidence over recent years suggests that the incidence of cardiovascular disease is increasing in HIV patients. The ankle-brachial index (ABI is a cheap and easy test that has been validated in the general population. Abnormal ABI values are associated with increased cardiovascular mortality. To date, six series of ABI values in persons with HIV have been published, but none was a prospective study. No agreement exists concerning the risk factors for an abnormal ABI, though its prevalence is clearly higher in these patients than in the general population. Whether this higher prevalence of an abnormal ABI is associated with a higher incidence of vascular events remains to be determined.

  5. [Measurement ofthe ankle-brachial pressure index (ABPI)].

    Kulisić, Sandra Marinović

    2012-10-01

    Measurement of the ankle-brachial pressure index, also known as ankle-brachial index or ankle-arm index is a ratio of the ankle blood pressure and brachial blood pressure. It is easy to perform and allows for diagnosis and further definition of the severity of peripheral arterial disease with sensitivity 90% and specificity 98%. The test is not appropriate for mild arterial changes as in case of comorbidity. Its further objectives are to identify patients at an higher risk of cardiovascular events. PMID:23193828

    Full Text Available Mo Al-Qaisi1, David M Nott1, David H King2, Sam Kaddoura11Imperial College, London, UK; 2Broomfield Hospital, Chelmsford, Essex, UKAbstract: Peripheral vascular disease affects some 12%–14% of the general population, and the majority of people with the disease are asymptomatic. The Ankle Brachial Pressure Index (ABPI test is widely used by a diverse range of practitioners (in the community and hospital setting in order to screen asymptomatic patients, diagnose patients with clinical symptoms, and to monitor patients who have had radiological or surgical intervention. This paper explains the theoretical basis of the ABPI test, as well as the relevance of the common modifications of the test. It explores the background to the quoted normal ranges for the ABPI test. It reviews the large body of literature that has developed on the association between ABPI and cardiovascular risk, as well as ABPI as a predictor for cardiovascular morbidity and mortality, highlighting the evidence that can inform practice. The review looks critically at the limitations of the ABPI test, providing practitioners with an evidence-based update on the importance and challenges of standardizing ABPI methodology. This paper highlights the influence of the key technical aspects of the ABPI test that all practitioners need to consider in order to be able to make more reliable and informed management decisions based on ABPI findings.Keywords: ankle, brachial, pressure, index, ABPI, update

  11. Ankle brachial pressure index of normal, healthy, younger adults.

    Niblo, Jane; Coull, Alison

    Doppler ultrasound and ankle brachial pressure index (ABPI) calculations are used in the assessment of lower limb vascularity, specifically to determine arterial deficiency. ABPI is important as it is used as an indicator when deciding management options for the treatment of leg ulceration. This study aimed to investigate the range of ABPI measurement, using Doppler ultrasound and sphygmomanometry in 36 young healthy adults aged 18-55 years. The findings show a mean ABPI in the left leg of 1.19 and a mean ABPI of 1.17 in the right leg which, while within the normal range, are consistently in the upper range and significantly higher than the acknowledged 'normal' midpoint of 1.0. It would appear that younger people will have ABPIs within the upper aspect of the normal range and well above the established norm of 1.0. PMID:24151719

    2012-07-01

    Peripheral vascular disease (PVD) is under-diagnosed in primary and acute settings. The use of Doppler ankle brachial pressure index (ABPI) is effective in diagnosing PVD , aid in determining aetiology of leg ulcers and is cost efficient in reducing the effects of atherosclerosis and cardiovascular events. The aim of this literature review was to review practitioners' experience in using Doppler ABPI, different skills used to measure ABPI and to examine practitioners' confidence in ABPI. The findings identified variation in method for Doppler measurement: including position of the artery, arm measurement, resting period and type of equipment for measuring blood pressure, variations in practitioners' training and experience have demonstrated variability in ABPI results. Although limited in number, the studies have demonstrated knowledge gap, and the need for training among health professionals. PMID:22875182

    2014-02-01

    Full Text Available Purpose: Several studies tried to assess the influence of rheumatoid arthritis (RA on peripheral arteries and found an association with later development of intimal thickness and atherosclerosis. We tried to uncover the prevalence of subclinical peripheral vascular disease (PVD in rheumatoid arthritis patients. Materials and Methods: This case control-study had involved sixty patients who were diagnosed with rheumatoid. Forty age, gender, and body mass index-matched healthy individuals were selected as the control group. All participants were non-smokers, non-hypertensive, and non-diabetics and had a normal lipid profile. The presence of peripheral arterial disease was evaluated by measuring the ankle-brachial pressure index (ABPI at the level of each artery of the lower limbs. An index of ≤0.9 was considered abnormal and a possible reflection of an underlying PVD. Results: Twenty three (38% out of the 60 RA patients demonstrated one or more abnormal arteries while only 3 (7.5% out of the 40 control individuals had abnormal results (p-value <0.001. A statistically significant association was noted between abnormal ABPI and RA disease severity as indicated by C-reactive protein (P-value <0.003, ESR (P-value <0.002, and positive serum rheumatoid factor (P-value <0.01. However, age, gender, and disease duration showed no link with abnormal ABPI. Conclusion: A higher prevalence of abnormal ABPI, and hence a possible higher incidence of subclinical atherosclerosis, was found in patients with RA. Further analytic studies are required to assess the relationship of RA with PVD.

  16. Transcutaneous oximetry compared to ankle-brachial-index measurement in the evaluation of percutaneous transluminal angioplasty

    Objective: To investigate transcutaneous oximetry as parameter of the microcirculation is correlated to ankle-brachial-index as parameter of the macrocirculation after peripheral angioplasty procedures. Design: Prospective study. Materials and methods: 60 patients suffering from intermittent claudication were scheduled for angioplasty treatment. 45 patients were considered as eligible for angioplasty after angiographic evaluation, 15 patients underwent angiography only. Transcutaneous oximetry measurements were performed before the procedure, at the end of intervention, 24 h as well as 2 and 4 weeks after percutaneous transluminal angioplasty. Ankle-brachial-indices were obtained before intervention, 24 h as well as 2 and 4 weeks later. Results: Ankle-brachial-indices increased significantly at 24 h after angioplasty in patients being treated with angioplasty. Transcutaneous oximetry values dropped significantly at the end of the procedure and returned close to the baseline levels at 2 and 4 weeks after angioplasty. Ankle-brachial-indices and transcutaneous oximetry were positively correlated before (r = 0.3833, p = 0.009) as well as 4 weeks after angioplasty (r = 0.4596, p = 0.001). Immediately after radiological interventions, ankle-brachial-indices and transcutaneous oximetry are not positively correlated. In patients undergoing angiography only, transcutaneous oximetry levels drop significantly immediately after angiography and remain at decreased levels even at 4 weeks after intervention. Conclusion: Transcutaneous oximetry as parameter of the microcirculation is positively correlated with ankle-brachial-index as parameter of the macrocirculation before and at 4 weeks after angioplasty. Intraarterial angiography leads to a sudden decrease in skin microcirculation without affecting macrocirculation. As indicated by a lack of recovery in transcutaneous oximetry levels after 4 weeks, angiography alone results in a prolonged impaired microcirculation which may

    Full Text Available BackgroundBrachial-ankle pulse wave velocity (baPWV is known to be a good surrogate marker of clinical atherosclerosis. Atherosclerosis is a major predictor for developing neuropathy. The goal of this study was to determine the relationship between baPWV and diabetic peripheral neuropathy (DPN in patients with type 2 diabetes.MethodsA retrospective cross-sectional study was conducted involving 692 patients with type 2 diabetes. The correlation between increased baPWV and DPN, neurological symptoms, and neurological assessment was analyzed. DPN was examined using the total symptom score (TSS, ankle reflexes, the vibration test, and the 10-g monofilament test. DPN was defined as TSS ≥2 and an abnormal neurological assessment. Data were expressed as means±standard deviation for normally distributed data and as median (interquartile range for non-normally distributed data. Independent t-tests or chi-square tests were used to make comparisons between groups, and a multiple logistic regression test was used to evaluate independent predictors of DPN. The Mantel-Haenszel chi-square test was used to adjust for age.ResultsPatients with DPN had higher baPWV and systolic blood pressure, and were more likely to be older and female, when compared to the control group. According to univariate analysis of risk factors for DPN, the odds ratio of the baPWV ≥1,600 cm/sec was 1.611 (95% confidence interval [CI], 1.072 to 2.422; P=0.021 and the odds ratio in female was 1.816 (95% CI, 1.195 to 2.760; P=0.005.ConclusionIncreased baPWV was significantly correlated with peripheral neuropathy in patients with type 2 diabetes.

    2014-06-01

    The aim in this study was to identify the cardiovascular risk in patients suffering from white coat hypertension (WCH) by determining the ankle brachial index (ABI) with an automatic oscillometric sphygmomanometer. The study was undertaken in a Brazilian city between August 2010 and June 2011. The study variables were age, ethnic origin, marital status, education level, profession, weight, height, waist circumference, arm and ankle blood pressure (BP), and ABI. Analysis of variance was used for repeated measures and Tukey's test for multiple comparisons of means. The linear relationship between systolic BP levels and ankle brachial indices was verified using Pearson's correlation coefficient. Results were expressed as mean values ± standard errors of means, and differences were considered statistically significant when P < .05. Study participants were 135 subjects, including 37% normotensive, 37% hypertensive (HT), and 26% WCH patients. WCH individuals revealed intermediate risk in the analysis of the clinical variables. Alterations compatible with peripheral obstructive arterial disease and arterial calcification were observed only in the HT and WCH groups. These findings lead to the premise that WCH should not be viewed as a benign condition. The measurement of the ABI should be considered in the clinical approach of patients and professionals should use it as an instrument for cardiovascular risk assessment in routine health care delivery.

    Full Text Available The ankle - brachial pressure index (ABI, which is the ratio of ankle to brachial systolic blood pressure, is the golden standard for the diagnosis of peripheral arterial disease (PAD and is a highly specific method for the assessment of vascular risk in otherwise asymptomatic patients . ABI value of individual with daily alcohol level >60g/d was significantly lower consumption of less than 60g/d had an inverse association with peripheral atherosclerosis whereas consumption of 60 g/d or more had a positive association. Studies have shown the sensitivity of ABPI is 90% with a corresponding 98% specificity for detecting hemodynamically significant (Serious stenosis >50% in major leg arteries, defined by angiogram. AIMS AND OBJECTIVES : To determine the prevalence of peripheral vascular disease in chronic alcoholics using ankle to brachial index and to compare the values of ankle brachial index in chronic alcoholics with age and sex matched healthy controls. MATERIALS AND METHODS : In the present study, 50 cases consuming more than 60gm of absolute alcohol per day for more than 12 months attending out p atient department and admitted were enrolled. 50 age and sex matched healthy controls who have never consumed alcohol (never drinkers were also enrolled . After taking detailed history using Doppler ultrasound blood flow detector mean systolic pressure in upper limb and lower limb was calculated and then the mean ABI was calculated. This value was then compared with variables like LDL levels, Triglycerides levels, age, clinical symptoms of PVD, alcohol consumption amount and duration. RESULTS: It was observed that mean ABI was significantly lower (<0.9 in 11(22% cases and majority of them were between age group of 41 - 50 years. Of these only 7(14% showed clinical symptoms of PVD. The prevalence of PVD was 66% in those who consumed 61 - 70 grams alcohol per day for around 6 - 10 years. Results were found to be statistically significant. CONCLUSION

    2012-10-01

    Peripheral arterial occlusive disease is very common in the general population and it is mostly of atherosclerotic origin. About 50%-75% of patients are asymptomatic. Many studies have shown the ankle-brachial pressure index (ABPI) to be a simple and reliable test with high sensitivity (90%) and specificity (98%) in the diagnosis of hemodynamically relevant stenosis of an arterial segment and also in detection of asymptomatic patients. The values of ABPI ABPI > 1.40 is associated with arterial calcification and wall stiffening. This test is highly specific (92.7%) in predicting future cardiovascular and cerebrovascular risk and could provide a tool for more focused prevention strategies. PMID:23814974

  8. Ankle Brachial Index: simple non-invasive estimation of peripheral artery disease

    Pieniak, Marcin; Cieślicki, Krzysztof; Żyliński, Marek; Górski, Piotr; Murgrabia, Agnieszka; Cybulski, Gerard

    2014-11-01

    According to international guidelines, patients with Peripheral Artery Disease (PAD) are burdened with high cardiovascular risk. One of the simplest, non-invasive methods for PAD detection is the ankle-brachial index (ABI) measurement. The ABI is calculated as the ratio of systolic blood pressure at the ankle (pressure in the posterior tibial artery or the dorsal artery) to the systolic pressure in the arm (in the brachial artery) when the body is in a horizontal position. The physiological value of the ABI is assumed to be between 1 and 1.3; however, these limits vary from study to study. A value less than 0.9 indicates PAD. Some authors propose also measuring the ABI on both sides of the body to highlight possible differences in blood pressure between the opposite arterial segments. The aim of this study was to perform a meta-analysis of the ABI diagnostic criteria used in different publications. Additionally, ABI measurements were performed on 19 healthy patients in age ranged from 20 to 63 years. The results showed a slight dependence between age and the differences between the values obtained from left and right sides of the body.

    2012-12-01

    . The ankle-brachial index was calculated for each artery of the lower limb. It was considered normal ankle-brachial index from 0.9 to 1.3. RESULTS: We diagnosed peripheral arterial disease and poorly compressible arteries in 26.9 and 30.8% of hemodialysis patients and in 33 and 22.7% of the Control Group. In hemodialysis patients, we found abnormal ankle-brachial index in 75% of symptomatic patients (p=0.005, in 67.3% of men and 31% of women (p<0.005, in 78.6% of the elderly, 34.8% of young adults (p<0.01, and 76.9% of diabetics (p<0.005 versus nondiabetic. These patients had a higher prevalence of severe peripheral arterial disease than the Control Group. CONCLUSIONS: Abnormal ankle-brachial index was very prevalent in the groups studied; however, hemodialysis patients had more severe changes, when compared to the Control Group. Diabetes mellitus, male gender, and advanced age were important risk factors for abnormal ankle-brachial index in hemodialysis patients. The ankle-brachial index was a good method of screening for the studied changes; therefore, we suggest the routine use in the management of hemodialysis patients.

A cross-sectional study was carried out at a centre for heart and diabetic clinic in the state of Punjab on 1121 subjects (671 males and 450 females with type 2 diabetes mellitus. History of symptoms related to cardiovascular diseases was noted, and blood pressure and anthropometric measurements were recorded. Ankle-brachial index (ABI was measured using ultrasonic Doppler flow detector. Subjects with ABI ≤0.9 and ≥1.30 were classified as having low and high ABI, respectively. Females had a higher BMI and brachial-ankle pulse wave velocity (<0.001. Whereas, males had higher diastolic blood pressure and duration of type 2 diabetes mellitus. The differences of systolic blood pressure and ankle-brachial index were not found significant between the sexes. The prevalence of low ABI (<0.9 was 4.47% in men and 4.67% in women and high ABI (≥1.30 was prevalent in 14% of men and 10.45% of women. Age, BMI, baPWV, and blood pressures were significantly associated with ABI value in both sexes. The results suggested that the ABI might be used as a strong indicator for cardiovascular risk factors in type 2 diabetic subjects.

    Full Text Available The issue with the different levels of ankle-brachial index, as screening for LDL-receptor defective gene in newly detected asymptomatic severe hypercholesterolemia is less studied, but quite interesting. There have not been any studies on ankle-brachial index in patients with severe hypercholesterolemia in Bulgaria. Aim: To examine the difference between patients with severe hypercholesterolemia, who are carriers and non-carriers of LDL-R defective gene, with respect to their structural (ankle-brachial index characteristics of arterial wall. Methods and materials: 60 patients with documented severe hypercholesterolemia >7.5 mmol/l satisfying the Simon-Broom criteria for clinically established and probable Familial Hypercholesterolemia were studied. All of the patients had a negative stress echocardiography and not known coronary artery disease. The laboratory used was the Clinical Laboratory at the Medical University Plovdiv. The total cholesterol and triglycerides were measured with enzyme-colorimetry and cholesterol in high density lipoprotein and cholesterol in low density lipoprotein with direct automatic analyses. Apolipoproteins were calculated by immunoturbodimetric method. The biochemical analyzer Konelab 60i was used in all the measurements. Results: According to whether there were or were not molecular defects, patients were assigned to two groups: carriers (11 patients, 18 % and non-carriers (49 patients, 82 %.There was a statistically significant difference (p 0.05. We found no statistically significant difference between non-carriers and carriers with respect to body mass index (25.30 ± 0.40 vs 24.63 ± 0.45, respectively, t = 0.50; p > 0.05. There was not a statistically significant difference in levels of total cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol between carries (p>0.05. The cholesterol x years. score was significantly higher in the carries (440.36 ± 0.25 mmol-y/L, than in the non-carries (390.30 ± 0

    The purpose of this study was to investigate whether ankle-arm blood pressure (BP) difference (An-a) and ankle-brachial index (ABI) are consistent in treated hypertensive patients with obvious BP variation. This study enrolled 414 hypertensive patients (200 males; mean age, 61.3 ± 13.3 years) admitted to our hospital. BP of four limbs was simultaneously measured using four automatic BP measurement devices on the day of admission, and three and six day after admission. The An-a differences on systolic BP (SBP), diastolic BP (DBP), mean artery pressure (MAP), and pulse pressure (PP) in both sides were calculated, respectively. The relative decrease amplitude (RDA) of BP was calculated using the formula: RDA = (BP1 - BPn)/BP1. The ABI of the right side was calculated. From the first to the third measurement, arm SBP and DBP levels of both arms significantly decreased (right arm: SBP: 163.7 ± 18.4, 147.7 ± 15.3 vs. 135.4 ± 11.7 mm Hg; P ankle SBP (right ankle: 182.1 ± 22.1, 147.7 ± 15.3 vs. 153.4 ± 16.6 mm Hg; P < .05) and DBP (84.8 ± 13.4, 79.9 ± 11.6 vs. 75.8 ± 9.8 mm Hg; P < .05) of both sides also significantly decreased. The mean An-a of three measurements of both sides was consistent at the levels of about 20 mm Hg on SBP and PP, 7 mm Hg on MAP, and 0 mm Hg on DBP. However, sABI gradually increased from the first to the third measurement.In treated hypertensive patients, the An-a differences on SBP, DBP, PP, and MAP are generally consistent, but sABI is associated with underlying SBP levels.

    2012-06-01

    Previous studies have shown that there was a correlation between low ankle brachial pressure index (ABPI) and the presence of the coronary artery disease (CAD). However, few studies have investigated the correlation between ABPI and the severity of CAD by using a scoring system. The authors aimed to investigate this correlation by using ABPI and CAD diagnosed by coronary angiography (CAG). A total of 213 consecutive patients awaiting CAG in Maharaj Nakorn Chiang Mai Hospital from July 2009 to November 2009 were enrolled in this study. The ABPI was measured before CAG. The severity of CAD was graded on CAG by using SYNTAX scores. The authors found a significantly negative correlation between ABPI and SYNTAX scores (correlation coefficient = -.172, P = .01). The authors concluded that ABPI appeared to correlate negatively with the severity of CAD in the Thai population. PMID:22561522

  19. Oxidized low-density lipoprotein and ankle-brachial pressure index in patients with clinically evident peripheral arterial disease

    Ruben Miguel Ayzin Rosoky

    2010-01-01

    Full Text Available OBJECTIVES: To investigate whether oxidized low-density lipoprotein is a suitable predictor of peripheral arterial disease severity. The role of oxidized low-density lipoprotein in the pathogenesis of atherosclerosis has already been investigated. Its relevance as a predictor of the appearance and worsening of coronary arterial disease is also well known. However, the same is not true regarding peripheral arterial disease. METHOD: Eighty-five consecutive patients with an ankle-brachial pressure index (ABPI < 0.9 and the presence of either intermittent claudication or critical lower leg ischemia were included. The plasma level of IgG autoantibodies against oxidized low-density lipoprotein was evaluated through an enzyme-linked immunosorbent assay. The results were categorized into quartiles according to the ankle-brachial pressure index (a marker of peripheral arterial disease severity, and significant differences were investigated with the Kruskal-Wallis test. RESULTS: There was no significant difference between the quartiles for this population (p = 0.33. No correlation was found between the ankle-brachial pressure index and oxidized low-density lipoprotein levels in subjects with clinically evident peripheral arterial disease with a wide range of clinical manifestations. CONCLUSIONS: Oxidized low-density lipoprotein is not a good predictor of peripheral arterial disease severity.

    2014-01-01

    Background The prevalence of metabolic syndrome (MetS) increased recently and there was still not a screening index to predict MetS.The aim of this study was to estimate whether brachial-ankle pulse wave velocity (baPVVV),a novel marker for systemic arterial stiffness,could predict MetS in Chinese community population.Methods A total of 2 191 participants were recruited and underwent medical examination including 1 455 men and 756 women from June 2011 to January 2012.MetS was diagnosed according to the criteria of the International Diabetes Federation (IDF).Multiple Logistic regressions were conducted to explore the risk factors of MetS.Receiver operating characteristic (ROC) curve was performed to estimate the ideal diagnostic cutoff point of baPWV to predict MetS.Results The mean age was (45.35±8.27) years old.In multiple Logistic regression analysis,the gender,baPWV and smoking status were risk factors to MetS after adjusting age,gender,baPWV,walk time and sleeping time.The prevalence of MetS was 17.48% in 30-year age population in Shanghai.There were significant differences (X2=96.46,P <0.05) between male and female participants on MetS prevalence.According to the ROC analyses,the ideal cutoff point of baPWV was 1 358.50 cm/s (AUC=60.20%) to predict MetS among male group and 1 350.00 cm/s (AUC=70.90%) among female group.Conclusion BaPWV may be considered as a screening marker to predict MetS in community Chinese population and the diagnostic value of 1 350.00 cm/s was more significant for the female group.

  1. Automated oscillometric determination of the ankle-brachial index: a systematic review and meta-analysis.

    Verberk, Willem J; Kollias, Anastasios; Stergiou, George S

    2012-09-01

    Measurement of the ankle-brachial index (ABI) using a Doppler device is widely used to identify subjects with peripheral artery disease (PAD), and those who are at high risk of cardiovascular disease. This paper presents a systematic review (Medline/PubMed, Embase and Cochrane) and meta-analysis of studies assessing the usefulness of automated oscillometric devices for ABI estimation and PAD detection compared with the conventional Doppler method. A total of 25 studies including 4186 subjects were analyzed. A random-effects model analysis showed that the average oscillometric ABI was similar to the Doppler ABI (mean difference ± s.e. 0.020 ± 0.018, P=0.3) but that the absolute differences were significant (0.048 ± 0.009, Parm-leg measurements resulted in a smaller difference between the average oscillometric ABI value and the average Doppler ABI value than did sequential measurements (-0.012 ± 0.022 vs. 0.040 ± 0.026, respectively, P<0.01). The average sensitivity and specificity of the oscillometric ABI estimation in PAD diagnosis was 69 ± 6% and 96 ± 1%, respectively (with Doppler ABI taken as the reference). These data suggest that an automated ABI measurement obtained by oscillometric blood pressure monitors is a reliable and practical alternative to the conventional Doppler measurement for the detection of PAD. To increase the sensitivity of the PAD diagnosis based on an oscillometric ABI, a higher threshold of 1.0 might be preferable. PMID:22739420

  2. The product of resting heart rate times blood pressure is associated with high brachial-ankle pulse wave velocity.

    Anxin Wang

    Full Text Available OBJECTIVE: To investigate potential associations between resting heart rate, blood pressure and the product of both, and the brachial-ankle pulse wave velocity (baPWV as a maker of arterial stiffness. METHODS: The community-based "Asymptomatic Polyvascular Abnormalities in Community (APAC Study" examined asymptomatic polyvascular abnormalities in a general Chinese population and included participants with an age of 40+ years without history of stroke and coronary heart disease. Arterial stiffness was defined as baPWV≥1400 cm/s. We measured and calculated the product of resting heart rate and systolic blood pressure (RHR-SBP and the product of resting heart rate and mean arterial pressure (RHR-MAP. RESULTS: The study included 5153 participants with a mean age of 55.1 ± 11.8 years. Mean baPWV was 1586 ± 400 cm/s. Significant (P<0.0001 linear relationships were found between higher baPWV and higher resting heart rate or higher arterial blood pressure, with the highest baPWV observed in individuals from the highest quartiles of resting heart rate and blood pressure. After adjusting for confounding parameters such as age, sex, educational level, body mass index, fasting blood concentrations of glucose, blood lipids and high-sensitive C-reactive protein, smoking status and alcohol consumption, prevalence of arterial stiffness increased significantly (P<0.0001 with increasing RHR-SBP quartile (Odds Ratio (OR: 2.72;95%Confidence interval (CI:1.46,5.08 and increasing RHR-MAP (OR:2.10;95%CI:1.18,3.72. Similar results were obtained in multivariate linear regression analyses with baPWV as continuous variable. CONCLUSIONS: Higher baPWV as a marker of arterial stiffness was associated with a higher product of RHR-SBP and RHR-MAP in multivariate analysis. In addition to other vascular risk factors, higher resting heart rate in combination with higher blood pressure are risk factors for arterial stiffness.

  3. Perceptions of the ankle brachial index amongst podiatrists registered in Western Australia

    Chen Pamela Y

    2012-07-01

    Full Text Available Abstract Background The ankle brachial index (ABI is an objective diagnostic tool that is widely used for the diagnosis of peripheral arterial disease. Despite its usefulness, it is evident within the literature that many practitioners forgo using this screening tool due to limiting factors such as time. There is also no recommended technique for ABI measurement. The purpose of this study is to investigate the perceptions of the use of ABI clinically among Western Australian podiatrists. Methods This study was a cross sectional survey which evaluated the perceptions of the ABI amongst registered podiatrists in Western Australia. The study sample was obtained from the register of podiatrists listed with the Podiatrists Registration Board of Western Australia. Podiatrists were contacted by telephone and invited to participate in a telephone questionnaire. Chi-square tests were performed to determine if there was a statistically significant relationship between use of the ABI and podiatrists’ profile which included: sector of employment; geographical location; and length of time in practice. Results There is a statistically significant relationship (p=0.004 between podiatrists’ profile and the use of ABI, with higher usage in the tertiary hospital setting than in private practice. Length of time spent in practice had no significant impact on ABI usage (p=0.098. Time constraints and lack of equipment were key limiting factors to performing the ABI, and no preferred technique was indicated. Conclusion Western Australian podiatrists agree that the ABI is a useful tool for lower limb vascular assessment, however, various factors influence uptake in the clinical setting. This study suggests that a podiatrists’ profile has a significant influence on the use of the ABI, which may be attributed to different patient types across the various settings. The influence of time spent in practice on ABI usage may be attributed to differences in clinical

  4. Profound influence of different methods for determination of the ankle brachial index on the prevalence estimate of peripheral arterial disease

    Allenberg Jens R

    2007-07-01

    Full Text Available Abstract Background The ankle brachial index (ABI is an efficient tool for objectively documenting the presence of lower extremity peripheral arterial disease (PAD. However, different methods exist for ABI calculation, which might result in varying PAD prevalence estimates. To address this question, we compared five different methods of ABI calculation using Doppler ultrasound in 6,880 consecutive, unselected primary care patients ≥65 years in the observational getABI study. Methods In all calculations, the average systolic pressure of the right and left brachial artery was used as the denominator (however, in case of discrepancies of ≥10 mmHg, the higher reading was used. As nominators, the following pressures were used: the highest arterial ankle pressure of each leg (method #1, the lowest pressure (#2, only the systolic pressure of the tibial posterior artery (#3, only the systolic pressure of the tibial anterior artery (#4, and the systolic pressure of the tibial posterior artery after exercise (#5. An ABI Results The estimated prevalence of PAD was lowest using method #1 (18.0% and highest using method #2 (34.5%, while the differences in methods #3–#5 were less pronounced. Method #1 resulted in the most accurate estimation of PAD prevalence in the general population. Using the different approaches, the odds ratio for the association of PAD and cardiovascular (CV events varied between 1.7 and 2.2. Conclusion The data demonstrate that different methods for ABI determination clearly affect the estimation of PAD prevalence, but not substantially the strength of the associations between PAD and CV events. Nonetheless, to achieve improved comparability among different studies, one mode of calculation should be universally applied, preferentially method #1.

    Aortic arch calcification (AoAC) is associated with cardiovascular and all-cause mortality in end-stage renal disease population. AoAC can be simply estimated with an AoAC score using plain chest radiography. The objective of this study is to evaluate the association of AoAC with brachial-ankle pulse wave velocity (baPWV) and cardiomegaly in patients who have undergoing hemodialysis (HD).We retrospectively determined AoAC and cardiothoracic ratio (CTR) by chest x-ray in 220 HD patients who underwent the measurement of baPWV. The values of baPWV were measured by an ankle-brachial index-form device. Multiple stepwise logistic regression analysis was used to identify the factors associated with AoAC score >4.Compared patients with AoAC score ≦4, patients with AoAC score >4 had older age, higher prevalence of diabetes and cerebrovascular disease, lower diastolic blood pressure, higher baPWV, higher CTR, higher prevalence of CTR ≧50%, lower total cholesterol, and lower creatinine level. After the multivariate stepwise logistic analysis, old age, cerebrovascular disease, high baPWV (per 100 cm/s, odds ratio [OR] 1.065, 95% confidence interval [CI] 1.003-1.129, P = 0.038), CTR (per 1%, OR 1.116, 95% CI 1.046-1.191, P = 0.001), and low total cholesterol level were independently associated with AoAC score >4.Our study demonstrated AoAC severity was associated with high baPWV and high CTR in patients with HD. Therefore, we suggest that evaluating AoAC on plain chest radiography may be a simple and inexpensive method for detecting arterial stiffness in HD patients. PMID:27175684

    2006-02-01

    Full Text Available Abstract Background A low ankle-brachial index (ABI is associated with increased risk of coronary heart disease, stroke, and death. Regression model parameter estimates may be biased due to measurement error when the ABI is included as a predictor in regression models, but may be corrected if the reliability coefficient, R, is known. The R for the ABI computed from DINAMAP™ readings of the ankle and brachial SBP is not known. Methods A total of 119 participants in both the Atherosclerosis Risk in Communities (ARIC study and the NHLBI Family Heart Study (FHS had repeat ABIs taken within 1 year, using a common protocol, automated oscillometric blood pressure measurement devices, and technician pool. Results The estimated reliability coefficient for the ankle systolic blood pressure (SBP was 0.68 (95% CI: 0.57, 0.77 and for the brachial SBP was 0.74 (95% CI: 0.62, 0.83. The reliability for the ABI based on single ankle and arm SBPs was 0.61 (95% CI: 0.50, 0.70 and the reliability of the ABI computed as the ratio of the average of two ankle SBPs to two arm SBPs was estimated from simulated data as 0.70. Conclusion These reliability estimates may be used to obtain unbiased parameter estimates if the ABI is included in regression models. Our results suggest the need for repeated measures of the ABI in clinical practice, preferably within visits and also over time, before diagnosing peripheral artery disease and before making therapeutic decisions.

    Peripheral artery occlusive disease and vascular calcification are highly prevalent in hemodialysis (HD) patients, however the association of the combination of ankle-brachial index (ABI) and aortic arch calcification (AoAC) with clinical outcomes in patients undergoing HD is unknown. In this study, we investigated whether the combination of ABI and AoAC is independently associated with overall and cardiovascular mortality in HD patients. The median follow-up period was 5.7 years. Calcification of the aortic arch was assessed by chest X-ray. Forty-seven patients died including 24 due to cardiovascular causes during the follow-up period. The study patients were stratified into four groups according to an ABI 4 or ≤4 according to receiver operating characteristic curve. Those with an ABI  4 (vs. ABI ≥ 0.95 and AoAC score ≤ 4) were associated with overall (hazard ratio [HR], 4.913; 95% confidence interval [CI], 1.932 to 12.497; p = 0.001) and cardiovascular (HR, 3.531; 95% CI, 1.070 to 11.652; p = 0.038) mortality in multivariable analysis. The combination of a low ABI and increased AoAC was associated with increased overall and cardiovascular mortality in patients undergoing HD. PMID:27608939

    Improvement in quality of life (QoL) is a primary treatment goal for patients with peripheral arterial disease (PAD). The current study aimed to quantify improvement in the health status of PAD patients following peripheral revascularization using the peripheral artery questionnaire (PAQ) and ankle-brachial index (ABI), and to evaluate possible correlation between the two methods. The PAQ and ABI were assessed in 149 symptomatic PAD patients before, and three months after peripheral revascularization. Mean PAQ summary scores improved significantly three months after revascularization (+49.3 ± 15 points, p PAQ scores relating to patient symptoms showed the largest improvement following revascularization. The smallest increases were seen in reported treatment satisfaction (all p's PAQ. Twenty-two percent of PAD patients were identified as having a poor response to revascularization (increase in ABI PAQ, although this was less marked than in patients with an increase in ABI > 0.15 following revascularization. In conclusion, data from the current study suggest a significant correlation between improvement in patient-reported outcomes assessed by PAQ and ABI in symptomatic PAD patients undergoing peripheral revascularization.

As expected the ABI of treated limbs showed significant improvement post-revascularization (p < 0.001. ABI after revascularization correlated with patient-reported changes in the physical function and QoL domains of the PAQ. Twenty-two percent of PAD patients were identified as having a poor response to revascularization (increase in ABI < 0.15. Interestingly, poor responders reported improvement in symptoms on the PAQ, although this was less marked than in patients with an increase in ABI > 0.15 following revascularization. In conclusion, data from the current study suggest a significant correlation between improvement in patient-reported outcomes assessed by PAQ and ABI in symptomatic PAD patients undergoing peripheral revascularization.

    Full Text Available Background: Given the lack of consistency in the literature regarding the reliability of the ankle-brachial index (ABI as a valid screening tool and an independent risk indicator of cardiovascular events and mortality, we compared it with angiography as a reference standard test.Methods: This case-control study, conducted between 2010 and 2011 in Tehran Heart Center, recruited 362 angiographically confirmed cases of coronary artery disease (CAD and 337 controls. A standard protocol was used to measure the ABI and different CAD risk factors.Results: A low ABI had specificity of 99.7%, positive predictive value of 95.8%, negative predictive value of 49.8%, sensitivity of 64%, likelihood ratio of 24.07, and odds ratio (OR of 22.79 (95%CI: 3.06-69.76. The role of the associated risk factors was evaluated with OR (95%CI, with the variables including gender 3.15 (2.30-4.30, cigarette smoking 2.72 (1.86-3.99, family history 1.72 (1.17-2.51, diabetes 1.66 (1.15-2.4, and dyslipidemia 1.38 (1.02-1.88. In a multivariate model, the following variables remained statistically significantly correlated with CAD [OR (95%CI]: ABI 13.86 (1.78-17.62; gender 3.69 (2.43- 5.58; family history of CAD 2.18 (1.41-3.37; smoking 1.69 (1.08-2.64; age 1.04 (1.02-1.06.Conclusions: A low ABI had specificity of 99.7%; however, because of its low sensitivity (64%, we should consider CAD risk factors associated with a low ABI in order to use it as a first-line screening test.

    Full Text Available Background and Aims: Atherosclerotic cardiovascular disease is the most common cause of mortality in patients with end-stage kidney disease. Chronic kidney disease patients often exhibit a deficiency in l-carnitine due to loss during hemodialysis (HD. We studied the effects of l-carnitine supplementation on brachial-ankle pulse wave velocity (baPWV, a marker of atherosclerosis, in HD patients. Methods: This was a prospective, open-label, randomized, parallel controlled, multi-center trial testing the anti-atherosclerotic efficacy of oral l-carnitine administration (20 mg/kg/day. HD patients (n = 176, mean age, 67.2 ± 10.3 years old; mean duration of HD, 54 ± 51 months with plasma free l-carnitine deficiency (<40 μmol/L were randomly assigned to the oral l-carnitine group (n = 88 or control group (n = 88 and monitored during 12 months of treatment. Results: There were no significant differences in baseline clinical variables between the l-carnitine and control groups. l-carnitine supplementation for 12 months significantly increased total, free, and acyl carnitine levels, and reduced the acyl/free carnitine ratio. The baPWV value decreased from 2085 ± 478 cm/s at baseline to 1972 ± 440 cm/s after six months (p < 0.05 to 1933 ± 363 cm/s after 12 months (p < 0.001 of l-carnitine administration, while no significant changes in baPWV were observed in the control group. Baseline baPWV was the only factor significantly correlated with the decrease in baPWV. Conclusions: l-carnitine supplementation significantly reduced baPWV in HD patients. l-carnitine may be a novel therapeutic strategy for preventing the progression of atherosclerotic cardiovascular disease.

    Background There is only limited data on the potential association between thyroid dysfunction and peripheral arterial disease (PAD). Objective The aim of our study was to investigate the potential association of thyroid function, as defined by serum concentrations of the clinically used primary thyroid function marker thyrotropin [i.e. thyroid-stimulating hormone (TSH)] and 3,5-diiodothyronine (3,5-T2), with the ankle-brachial index (ABI) as a marker of PAD. Methods We used data from 5,818 individuals from three cross-sectional population-based studies conducted in Northeast (SHIP-2 and SHIP-TREND) and Central Germany (CARLA). Measurement of serum TSH concentrations was conducted in one central laboratory for all three studies. In a randomly selected subpopulation of 750 individuals of SHIP-TREND, serum 3,5-T2 concentrations were measured with a recently developed immunoassay. ABI was measured either by a hand-held Doppler ultrasound using the Huntleigh Dopplex D900 or palpatorily by the OMRON HEM-705CP device. Results Serum TSH concentrations were not significantly associated with ABI values in any of the three studies. Likewise, groups of individuals with a TSH <0.3 mIU/l or with a TSH ≥3.0 mIU/l had no significantly different ABI values in comparison with individuals with a TSH in the reference range. Analyses regarding TSH within the reference range or serum 3,5-T2 concentrations did not reveal consistent significant associations with the ABI. No sex-specific associations were detected. Conclusions The results of our study do not substantiate evidence for an association between thyroid function and PAD, but further studies are needed to investigate the associations of overt forms of thyroid dysfunction with PAD.

    Full Text Available Background: Brachial monomelic amyotrophy (BMMA is known to affect the central cervical cord gray matter resulting in single upper limb atrophy and weakness. Settings and Design: Case series of BMMA patients who underwent somatosensory evoked potentials (SEP studies at a tertiary referral center. Aims: We proposed to record Multichannel Somatosensory Evoked Potentials (MCSSEP from median and ulnar nerves with neck in neutral and neck fully flexed position in 17 patients with classical BMMA seen over three years. Materials and Methods: Recordings were done from both median (MN and ulnar nerves (UN. N9, P9, N13, N20 potentials were recorded and amplitudes measured. SSEPs were performed in 22 age-matched healthy men. Amplitudes of cervical response were calculated by N13/P9 ratio and compared in both positions. Results: Among the controls N13 amplitude was always normal {MN: mean N13/P9 - 0.96 in neutral; 0.95 in flexed}{UN: mean N13/P9 - 0.82 in neutral; 0.83 in flexed}, and mean amplitudes did not reveal any difference in both conditions ( P >0.05. Among 17 patients N9, P9 and N20 responses were normal in neutral position. Flexion showed no change in latency or amplitude of N9 and N20 responses ( P -0.63 whereas the N13 response was abnormal in at least one tested nerve in the affected limb (MN: P < 0.01; UN: P < 0.01. During flexion, N13 response was abnormal in 14 (82% patients after MN stimulation and in all 17(100% after UN stimulation {MN: mean N13/P9 - 0.62 in neutral; 0.38 in flexed}{UN: mean N13/P9 - 0.55 in neutral; 0.31 in flexed}. Conclusion: MCSSEP in BMMA with neck flexion caused a significant reduction of the cervical N13 response indicating segmental cervical cord dysfunction.

    Full Text Available OBJECTIVES: Peripheral vascular disease is one of the macrovascular complications of diabetes mellitus. The purpose of this study was to examine the peripheral arterial disease (PAD complicating type 2 diabetes, in particular the influence of PAD on the risk of coronary artery disease. METHODS: Randomly selected T2DM pat ients admitted to Basaweshwara Teaching and General Hospital were included. In addition to a detailed history and physical examination, anthropometric parameters like body mass index was measured. Relevant laboratory investigations were performed. Modified Rose questionnaire was used to diagnose coronary artery disease (CAD. Colour Doppler examination of the arteries of the lower limbs was performed. A cut off of 7% were significant predictors of PAD. Older age, higher HbA1c levels microalbuminuria and deranged lipid profile were found to be significant predictors of CAD. CONCLUSION: We found evidence of PAD in 16% of type 2 dia betics using ankle brachial index. The prevalence of CAD was higher in patients with PAD. So there is definite and strong correlation between PAD and CAD. Thus the early diagnosis of PAD should alert the clinician to a high probability of underlying CAD.

  20. Importance of the ankle-brachial pressure index in the diagnosis of coronary artery disease in women with diabetes without anginal pain

    Clinical symptoms of coronary artery disease (CAD) are often atypical in women, particularly in those with diabetes mellitus. Therefore, a simple diagnostic test to identify a high-risk subset of women with diabetes who are likely to have CAD is important. A total of 407 consecutive patients (319 men and 88 women, age range 68±11 years) with suspected CAD, who were not complaining of anginal pain, were evaluated. Among these patients, 170 had diabetes. Stress myocardial perfusion imaging and simultaneous brachial and ankle blood pressure measurements were performed to obtain the ischemic total perfusion deficit (TPD) and ankle-brachial pressure index (ABI), respectively. Ischemic TPD was not significantly different between men and women, whereas ischemic TPD was significantly greater in diabetic patients than in non-diabetic patients (6.9±7.7% vs. 4.9±6.1%; P=0.005). In diabetic patients, ischemic TPD was not significantly different between men and women. However, women with ABI 10%, which is regarded as a scintigraphic indicator for coronary revascularization.

  1. Ankle-brachial index as indicator of chronic arterial insufficiency of the lower extremities and renal artery stenosis CT/DS angiography

    Full text: The aim is to validate the measurements of ankle -brachial index (ABI), as part of routine examination algorithm in conducting CTA/DSA of the extremities in patients suffering from PAD. Correlations between ABI values and renal artery stenosis. The present study includes 200 patients (138 men and 62 women, aged between 60 and 75 years). 130 of them were examined by a computer- tomography angiography - 95 men and 32 women. 70 patients were examined by digital subtraction angiography - 50 men and 20 women. Measurements of ankle-brachial index (ABI) were performed on all patients by measuring the systolic blood pressure on both brachial arteries and determine the peak pressure in both aa. dorsalis pedis. Statistical data processing. There are no patients in the study with ABI values above 0.7 that have established renal artery stenosis. All patients with severe atherosclerotic changes have values of the ABI below 0.7, and those with the most severe changes below 0.5. This fully corresponds to global data showing that values below 0.9 ABI show mild engagement, below 0.7 average, and below 0.5 severe involvement. According to the results of this survey sensitivity of ABI for renal arteries below 0.7 equals 100% and its specificity = 67.5%. For values of ABI below 0.5: Sensitivity =100%; Specificity = 83.85%. By determining ABI values both symptomatic and asymptomatic form of a PAD can be diagnosed. the method is fast, non-invasive, inexpensive and applicable everywhere. No special preparation of the patient is needed. The method can be used not only to assess the degree of commitment of the vessels of the lower limbs, but also as an indicator for the state of renal arteries in those patients

    2010-10-01

    Full Text Available Abstract Background Patients with incomplete recovery from obstetric brachial plexus injury (OBPI usually develop secondary muscle imbalances and bone deformities at the shoulder joint. Considerable efforts have been made to characterize and correct the glenohumeral deformities, and relatively less emphasis has been placed on the more subtle ones, such as those of the coracoid process. The purpose of this retrospective study is to determine the relationship between coracoid abnormalities and glenohumeral deformities in OBPI patients. We hypothesize that coracoscapular angles and distances, as well as coracohumeral distances, diminish with increasing glenohumeral deformity, whereas coracoid overlap will increase. Methods 39 patients (age range: 2-13 years, average: 4.7 years, with deformities secondary to OBPI were included in this study. Parameters for quantifying coracoid abnormalities (coracoscapular angle, coracoid overlap, coracohumeral distance, and coracoscapular distance and shoulder deformities (posterior subluxation and glenoid retroversion were measured on CT images from these patients before any surgical intervention. Paired Student t-tests and Pearson correlations were used to analyze different parameters. Results Significant differences between affected and contralateral shoulders were found for all coracoid and shoulder deformity parameters. Percent of humeral head anterior to scapular line (PHHA, glenoid version, coracoscapular angles, and coracoscapular and coracohumeral distances were significantly lower for affected shoulders compared to contralateral ones. Coracoid overlap was significantly higher for affected sides compared to contralateral sides. Significant and positive correlations were found between coracoscapular distances and glenohumeral parameters (PHHA and version, as well as between coracoscapular angles and glenohumeral parameters, for affected shoulders. Moderate and positive correlations existed between coracoid

    The purpose of this study was to analyze the influence of radiographic arterial calcification (RAC) on the clinical interpretation of ankle-brachial index (ABI) values in patients with diabetic foot ulcers. We analyzed a retrospective clinical database of 60 patients with diabetic foot ulcers from the Diabetic Foot Unit (Complutense University, Madrid, Spain) between January 2012 and March 2014. For each patient, anteroposterior XR-plains were evaluated, and the ABI and toe-brachial index (TBI) were assessed by an experienced clinician. To analyze the correlation among quantitative variables, we applied the Pearson correlation coefficient. Fifty percent (n = 9/18) of our patients with a normal ABI and RAC had a TBI Pearson correlation coefficient among the ABI and TBI in patients with an ABI < 1.4 (n = 46) was lesser (r = .484, P = .001) than in patients with an ABI < 1.4 but without RAC (n = 21; r = .686, P = .001). ABI values between 0.9 and 1.4 would be falsely considered as normal and could underestimate the prevalence of PAD, especially in patients with neuropathy, diabetic foot ulcers, or RAC.

    Objective. To assess MRI changes in the ankle and foot after physical exercise.Design and patients. Nineteen non-professional marathon runners and 19 age- and sex-matched controls volunteered for the study. All had ankle and foot MR images (1.5 T) taken in three perpendicular planes (STIR, T2F and T1FS sequences) within 3 h of running a full-length marathon (42.125 km). Three radiologists independently analysed the groups on a masked basis using a predefined form.Results. Severe bone marrow oedema was seen in one and slight bone marrow oedema in three marathon runners. Slight bone marrow oedema was found in three control subjects. Signal alteration within the soleus muscle, consistent with a grade 1 strain, was found in one marathon runner. Small punctate hyperintensities within the Achilles tendon were seen in 26% of the marathon runners and in 63% of controls (P=0.016). An increased amount of fluid in the retrocalcaneal bursa was found in one control and in none of the marathon runners. Small amounts of fluid in the retrocalcaneal bursa were seen in 68% of marathon runners and in 53% of controls. Grade 1 or 2 peritendinous joint fluid was found around 22% of tendons, among both marathon runners and controls, most often involving the tendon sheath of the flexor hallucis longus muscle. An increased amount of joint fluid was noted in 34% of the joints of the marathon runners, and in 18% of the controls.Conclusion. MRI shows several abnormalities in the ankle and foot both after marathon races and in asymptomatic physically active individuals without any preceding extraordinary strain. Recreational sports may lead to a number of positive MRI findings without correlation with clinical findings. (orig.)

  11. Clinical significance of inter-arm pressure difference and ankle-brachial pressure index in patients with suspected coronary artery disease

    Although measuring blood pressure at the bilateral brachia is common in medical practice, its clinical significance in patients with suspected coronary artery disease (CAD) has not been fully clarified. The method of this study was to define the significance of inter-arm systolic blood pressure difference in patients with suspected CAD, and to assess the relationship between inter-arm pressure difference and CAD, simultaneous brachial and ankle blood pressure measurements and stress myocardial single-photon emission computed tomography (SPECT) were performed in 386 consecutive patients with suspected CAD, excluding those with previous myocardial infarction or coronary revascularization. Subclavian artery stenosis, defined as ≥15 mmHg inter-arm systolic blood pressure difference, was found in 27 patients (7%). Age (65±12 vs 65±11 years), male sex (21/27 vs 244/359), prevalence of hypertension (63% vs 56%), hypercholesterolemia (63% vs 62%), diabetes mellitus (33% vs 38%), cigarette smoking (44% vs 41%) and family history of CAD (15% vs 12%) were similar between patients with subclavian artery stenosis and those without. The incidence of decreased ankle-brachial pressure index (ABI) was higher (37% vs 12%, p=0.001), and percentage ischemic myocardium as assessed by SPECT was greater (9.0±8.5% vs 5.6±6.6%, p=0.05) in patients with subclavian artery stenosis than in those without. Furthermore, significant correlations were observed between inter-arm pressure difference and percentage ischemic myocardium (r=0.13; p=0.01), and ABI (r=-0.26, p<0.0001). Among 386 patients, 283 underwent coronary angiography, and 63% of those who had inter-arm blood pressure difference had CAD. Furthermore, 83% of those CAD patients had multi-vessel CAD, which is regarded as a high-risk subset for subsequent cardiac events. Inter-arm pressure difference is often found in patients with suspected CAD, and is associated with significant CAD and peripheral artery disease. Thus, inter

Several factors and conditions interfering with blood pressure (BP control, such as excess sodium intake, obesity, diabetes, older age, kidney disease, and certain identifiable causes of hypertension are common in patients resistant to antihypertensive treatment. Arterial stiffness, measured by brachial-ankle pulse wave velocity (baPWV, is increasingly recognized as an important prognostic index and potential therapeutic target in hypertensive patients. The aim of this study was to determine whether there is an association between RH and arterial stiffness. Methods: This study included 1,620 patients aged ≥65 years who were referred or self-referred to the outpatient hypertension unit located at a single cardiovascular center. They were separated into normotensive, controlled BP, and resistant hypertension groups. Home BP, blood laboratory parameters, echocardiographic studies and baPWV all were measured. Results: The likelihood of diabetes mellitus was significantly greater in the RH group than in the group with controlled BP (odds ratio 2.114, 95% confidence interval [CI] 1.194–3.744, P=0.010. Systolic BP was correlated in the RH group significantly more than in the group with controlled BP (odds ratio 1.032, 95% CI 1.012–1.053, P=0.001. baPWV (odds ratio 1.084, 95% CI 1.016–1.156, P=0.015 was significantly correlated with the presence of RH. The other factors were negatively correlated with the existence of RH.Conclusion: In

    Full Text Available Abstract Background It has been suggested that periodontal disease may be an independent risk factor for the development of atherosclerosis. However, the relationship between periodontal disease and atherosclerosis has not been fully elucidated. This study aimed to assess the effects of periodontal disease on atherosclerosis. Methods The study design was a cross-sectional study. Subjects were 291 healthy male workers in Japan. We used the Community Periodontal Index of Treatment Needs (CPITN score, average probing depth and gingival bleeding index (rate of bleeding gums to assess the severity of periodontal disease. We also used the Brachial-Ankle Pulse Wave Velocity (baPWV as the index for the development of atherosclerosis. Results The unadjusted odds ratio (OR of atherosclerosis in relation to the CPITN score was 1.41 [95% CI: 1.16–1.73]. However, after adjustment for age, systolic blood pressure and smoking, the CPITN score had no relationship with atherosclerosis (adjusted OR: 0.91 [0.68–1.20]. Conclusion Our results show no relationship between mild periodontal disease and atherosclerosis after appropriate adjustments.

    The ankle-brachial blood pressure index (ABPI) has been recognized to have a predictive value for cardiovascular (CV) events and mortality in general or dialysis populations. However, the associations between ABPI and those outcomes have not been fully investigated in predialysis patients. The present study aimed to clarify the relationships between ABPI and both CV events and mortality in Japanese chronic kidney disease (CKD) patients not on dialysis. In this prospective observational study, we enrolled 320 patients with CKD stages 3-5 who were not on dialysis. At baseline, ABPI was examined and a low ABPI was defined as ABPI were risk factors for CV events. It was demonstrated that age, a history of cerebrovascular disease and low ABPI were determined as independent risk factors for CV mortality. In addition, age, body mass index and low ABPI were independently associated with all-cause mortality. In patients with CKD, low ABPI during the predialysis period is independently associated with poor survival and CV events, suggesting the usefulness of measuring ABPI for predicting CV events and patient survival in CKD.

    Background: Whole-body magnetic resonance angiography (WBMRA) permits noninvasive vascular assessment, which can be utilized in epidemiological studies. Purpose: To assess the relation between a low ankle brachial index (ABI) and high-grade stenoses in the pelvic and leg arteries in the elderly. Material and Methods: WBMRA was performed in a population sample of 306 subjects aged 70 years. The arteries below the aortic bifurcation were graded after the most severe stenosis according to one of three grades: 0-49% stenosis, 50-99% stenosis, or occlusion. ABI was calculated for each side. Results: There were assessable WBMRA and ABI examinations in 268 (right side), 265 (left side), and 258 cases (both sides). At least one {>=}50% stenosis was found in 19% (right side), 23% (left side), and 28% (on at least one side) of the cases. The corresponding prevalences for ABI <0.9 were 4.5%, 4.2%, and 6.6%. An ABI cut-off value of 0.9 resulted in a sensitivity, specificity, and positive and negative predictive value of 20%, 99%, 83%, and 84% on the right side, and 15%, 99%, 82%, and 80% on the left side, respectively, for the presence of a {>=} 50% stenosis in the pelvic or leg arteries. Conclusion: An ABI <0.9 underestimates the prevalence of peripheral arterial occlusive disease in the general elderly population.

    Magnetic resonance imaging (MRI) has become the primary imaging technique in the evaluation of brachial plexus pathology, and plays an important role in the identification, localization, and characterization of the cause. Improvements in MRI technique have helped in detecting changes in the signal intensity of nerves, subtle enhancement, and in detecting perineural pathology, thereby refining the differential diagnosis. The present review of the visualization of brachial plexus abnormalities using MRI is based on a review of 26 cases. The causes include trauma and a spectrum of non-traumatic causes, such as acute idiopathic/viral plexitis, metastases, immune-mediated plexitis, and mass lesions compressing the brachial plexus.

  1. Brachial plexus myoclonus.

    Banks, G.; Nielsen, V K; Short, M P; Kowal, C D

    1985-01-01

    Rhythmic myoclonus in an arm began abruptly following an injury and persisted continuously for six years. Topographical EMG showed abnormal activity confined to muscles innervated by the axillary and radial nerves from the posterior cord of the brachial plexus. Abduction of the arm above horizontal level stopped myoclonus and EMG discharges. EEG was normal. It is suggested that the myoclonus was caused by mechanical irritation of the posterior cord of the brachial plexus.

  7. The run-off resistance (ROR) assessed on MR angiograms may serve as a valid scoring system in patients with symptomatic peripheral arterial disease (PAD) and correlates with the ankle-brachial pressure index (ABI)

    Objective: To investigate the correlation between the hemodynamic parameter ankle-brachial pressure index (ABI) and the run-off resistance (ROR) assessed on MR angiograms (MRA) in patients with peripheral arterial disease (PAD) Fontaine Stage I and II and its potential as reliable reporting system in clinical routine. Methods: Contrast-enhanced MRA was performed in 321 PAD patients using a 1.5 T MR scanner with moving bed technique. The ROR and resting ABI were determined in each patient's leg and correlation analysis was performed using the Pearson test. Results: A significant negative correlation (r = −.513; p < .001) between ROR (mean 11.03 ± 5.42) and resting ABI (mean .81 ± .26) was identified. An even more pronounced correlation was found in patients younger than median age who had higher ABI values (r = −.608; p < .001). Conclusion: The ROR scoring system evaluated in this series correlates better with the ABI than previously published scoring systems and could be suggested as reporting system for routine MRA evaluation.

The current topic is concerned with various forms of brachial plexopathy, its clinical features, pathophysiology, imaging findings, and management. Idiopathic brachial neuritis (IBN), often preceded with antecedent events such as infection, commonly present with abruptonset painful asymmetric upper limb weakness with associated wasting around the shoulder girdle and arm muscles. Idiopathic hypertrophic brachial neuritis, a rare condition, is usually painless to begin with, unlike IBN. Hereditary neuralgic amyotrophy is an autosomal-dominant disorder characterized by repeated episodes of paralysis and sensory disturbances in an affected limb, which is preceded by severe pain. While the frequency of the episodes tends to decrease with age, affected individuals suffer from residual deficits. Neurogenic thoracic outlet syndrome affects the lower trunk of the brachial plexus. It is diagnosed on the basis of electrophysiology and is amenable to surgical intervention. Cancer-related brachial plexopathy may occur secondary to metastatic infiltration or radiation therapy. Traumatic brachial plexus injury is commonly encountered in neurology, orthopedic, and plastic surgery set-ups. Trauma may be a direct blow or traction or stretch injury. The prognosis depends on the extent and site of injury as well as the surgical expertise. PMID:23661957

    Full Text Available Abstract Background To investigate the presence of peripheral artery disease (PAD via the ankle brachial index (ABI in patients with known cardiovascular and/or cerebrovascular diseases or with at least one risk factor for atherothrombosis. Methods Patients with a history of atherothrombotic events, or aged 50-69 years with at least one cardiovascular risk factor, or > = 70 years of age were included in this multicenter, cross-sectional, non-interventional study (DIREGL04074. Demographics, medical history, physical examination findings, and physician awareness of PAD were analyzed. The number of patients with low ABI ( Results A total of 530 patients (mean age, 63.4 ± 8.7 years; 50.2% female were enrolled. Hypertension and dyslipidemia were present in 88.7% and 65.5% of patients, respectively. PAD-related symptoms were evident in about one-third of the patients, and at least one of the pedal pulses was negative in 6.5% of patients. The frequency of low ABI was 20.0% in the whole study population and 30% for patients older than 70 years. Older age, greater number of total risk factors, and presence of PAD-related physical findings were associated with increased likelihood of low ABI (p Conclusion Our results indicate that advanced age, greater number of total risk factors and presence of PAD-related physical findings were associated with increased likelihood of low ABI. These findings are similar to those reported in similar studies of different populations, and document a fairly high prevalence of PAD in a Mediterranean country.

  15. MR imaging of the brachial plexus

    Determining the cause of brachial plexopathy is often difficult. MR imaging allows for direct visualization of this region in multiple planes with high soft-tissue contrast. This paper defines the normal anatomy of the brachial plexus and demonstrates the ability of MR imaging to evaluate varied pathology in this region. Fifty-five patients with brachial plexopathy were evaluated with either a 1.5-T (General Electric, Milwaukee) or a 0.35-T (Diasonics, South San Francisco) superconducting MR system. Multiplanar, multiecho spin-echo images were obtained with either dual-coil imaging or a body coil. Individual fascicles to the brachial plexus were clearly separated from the subclavian artery and vein, clavicle, and surrounding musculature. Abnormalities well seen with MR imaging included primary tumors in the region of the brachial plexus, tumors metastatic to the brachial plexus, direct extension of pancoast tumors, postradiation fibrosis, and posttraumatic lesions, including fracture and edema

    Full Text Available Common carotid intima media thickness (CIMT and ankle brachial pressure index (ABPI are used as surrogate marker of atherosclerosis, and have been shown to correlate with arterial stiffness, however their correlation with global atherosclerotic burden has not been previously assessed. We compare CIMT and ABPI with atheroma burden as measured by whole body magnetic resonance angiography (WB-MRA.50 patients with symptomatic peripheral arterial disease were recruited. CIMT was measured using ultrasound while rest and exercise ABPI were performed. WB-MRA was performed in a 1.5T MRI scanner using 4 volume acquisitions with a divided dose of intravenous gadolinium gadoterate meglumine (Dotarem, Guerbet, FR. The WB-MRA data was divided into 31 anatomical arterial segments with each scored according to degree of luminal narrowing: 0 = normal, 1 = <50%, 2 = 50-70%, 3 = 70-99%, 4 = vessel occlusion. The segment scores were summed and from this a standardized atheroma score was calculated.The atherosclerotic burden was high with a standardised atheroma score of 39.5±11. Common CIMT showed a positive correlation with the whole body atheroma score (β 0.32, p = 0.045, however this was due to its strong correlation with the neck and thoracic segments (β 0.42 p = 0.01 with no correlation with the rest of the body. ABPI correlated with the whole body atheroma score (β -0.39, p = 0.012, which was due to a strong correlation with the ilio-femoral vessels with no correlation with the thoracic or neck vessels. On multiple linear regression, no correlation between CIMT and global atheroma burden was present (β 0.13 p = 0.45, while the correlation between ABPI and atheroma burden persisted (β -0.45 p = 0.005.ABPI but not CIMT correlates with global atheroma burden as measured by whole body contrast enhanced magnetic resonance angiography in a population with symptomatic peripheral arterial disease.

    2000-04-01

    Full Text Available The purpose of this study was to determine whether the ankle-brachial index (ABI could be used to predict the prognosis for a patient with intermittent claudication (IC. We studied 611 patients prospectively during 28 months of follow-up. We analyzed the predictive power of using various levels of ABI - 0.30 to 0.70 at 0.05 increments - in terms of the measure's specificity (association with a favorable outcome after exercise rehabilitation therapy and sensitivity (association with a poor outcome after exercise rehabilitation therapy. We found that using an ABI of 0.30 as a cut-off value produced the lowest margin of error overall, but the predictive power was still low with respect to identifying the patients with a poor prognosis after non-aggressive therapeutic treatment. Further study is needed to perhaps identify a second factor that could increase the sensitivity of the test.O objetivo deste estudo foi determinar a evolução da distância de marcha de pacientes com claudicação intermitente relacionando com o índice tornozelo-braço (ITB e o valor deste índice como fator preditivo para o prognóstico desses pacientes. Observou-se prospectivamente a evolução de 611 pacientes durante 28 meses. Analisamos o valor preditivo do ITB inicial usando vários valores de corte - 0.30 a 0.70 em incrementos de 0.05 - em relação à especificidade (associação com uma evolução favorável após tratamento clínico e sensibilidade (associação com uma evolução desfavorável após tratamento clínico. Encontramos o ITB de 0.30 como o valor de corte produzindo a menor margem de erro, mas seu valor preditivo ainda foi baixo para identificar os pacientes com mau prognóstico para o tratamento não invasivo. Estudos adicionais são necessários para se identificar um fator adicional que possa aumentar a sensibilidade do teste.

    Objective To investigate the clinical application and its influencing factors of ankle-brachial index (ABl) and toe-brachial index (TBI) in the diagnosis of arterial disease of lower extremity. Methods ABI and TBI were measured in 800 limbs of 402 patients with diabetes and/or hypertension hospitalized from July 2010 to February 2011 The patients were divided into narrow group (ABI<0.9), normal group (0.9≤ABI<1.3), and calcification group (ABI≤ 1.3) according to the value of ABI, and also into narrow group (TBI<0.7) and normal group (TBI≥ 0.7) according to the value of TBL The correlation of ABI with TBI was analyzed, and the differences in age, obesity parameters, biochemical indicators and other factors were compared between the groups. Influence of high-sensitivity C-reactive protein (hs-CRP) on ABI and TBI was further analyzed. Results Only when ABI<0.9, ABI and TBI have significant correlation (r=0.826, p<0.0l). When the group comparison based on ABI values, it was shown that the age and hs-CRP were significantly higher in the narrow group than in the normal group and calcification group (P<0.0l). The comparison between groups based on TBI values indicated that the age, systolic blood pressure and hs-CRP in the narrow group were significantly higher than those in the normal group (P<0.01 or P<0.05), ABI and TBI in the normal hs-CRP group were significantly higher than those in high hs-CRP group (P<0.05). Conclusion Hs-CRP may play an important role in the development and progression in peripheral arterial atherosclerosis. Therefore, ABI and TBI measurements in combination with hs-CRP level can improve early diagnosis of arterial disease of lower extremity%目的 探讨踝肱指数(ABI)、趾肱指数(TBI)在下肢动脉疾病诊断中的应用价值及其影响因素.方法 对2010年7月-2011年2月收治的402例糖尿病和(或)高血压患者的800条下肢行ABI和TBI检查,根据ABI结果分为狭窄组(ABI<0.9),正常组(0.9≤ABI< 1.3)

    Full Text Available Systolic time interval (STI is an established noninvasive technique for the assessment of cardiac function. Brachial STIs can be automatically determined by an ankle-brachial index (ABI-form device. The aims of this study are to evaluate whether the STIs measured from ABI-form device can represent those measured from echocardiography and to compare the diagnostic values of brachial and echocardiographic STIs in the prediction of left ventricular ejection fraction (LVEF <50%. A total of 849 patients were included in the study. Brachial pre-ejection period (bPEP and brachial ejection time (bET were measured using an ABI-form device and pre-ejection period (PEP and ejection time (ET were measured from echocardiography. Agreement was assessed by correlation coefficient and Bland-Altman plot. Brachial STIs had a significant correlation with echocardiographic STIs (r = 0.644, P<0.001 for bPEP and PEP; r  = 0.850, P<0.001 for bET and ET; r = 0.708, P<0.001 for bPEP/bET and PEP/ET. The disagreement between brachial and echocardiographic STIs (brachial STIs minus echocardiographic STIs was 28.55 ms for bPEP and PEP, -4.15 ms for bET and ET and -0.11 for bPEP/bET and PEP/ET. The areas under the curve for bPEP/bET and PEP/ET in the prediction of LVEF <50% were 0.771 and 0.765, respectively. Brachial STIs were good alternatives to STIs obtained from echocardiography and also helpful in prediction of LVEF <50%. Brachial STIs automatically obtained from an ABI-form device may be helpful for evaluation of left ventricular systolic dysfunction.

    2010-01-01

    Brachial plexus tumours are a rare entity. Schwannomas are benign nerve sheath tumours and only about 5% arise from the brachial plexus. Due to its rarity and complex anatomical location they can pose a formidable challenge to surgeons. We present a case of a young patient who presented with an axillary swelling three months after a lymph node biopsy from the same axilla, which turned out to be a Schwannoma arising for the medial cord of the brachial plexus.

  12. MRI diagnosis of brachial plexus preganglionic injury

    Objective: To evaluate MRI in diagnosing brachial plexus preganglionic injury. Methods: Twenty cases with brachial plexus preganglionic injury underwent MR scanning before operation. MR imaging was obtained by GE Signa EXCITE 1.5 T scanner. The scanning sequences included SE T1WI, FSE T2WI, T2WI STIR and 3 D Fast imaging employing steady state with phase cycled (3D-FIESTA-c). All the patients had exploration of the supraclavicular plexus and electrophysiology examination. And the accuracy, sensitivity and specificity of MRI in diagnosing preganglionic brachial plexus injury were calculated with the standards of surgical and EMG results. Results: Among the 73 pairs of injured roots, MR imaging detected the abnormalities in 63 pairs. The accuracy, sensitivity and specificity of MRI in diagnosing preganglionic brachial plexus injury were 86.5% (83/96), 86.3% (63/73), 87.0% (20/23), respectively. The direct signs of brachial plexus preganglionic injury included (1) lack or mutilation of nerve root in 54 pairs (85.7%), (2) coarsening, bending, stiff course and unable to be traced to the intervertebral foramen continuously in 9 pairs (14.3%). The indirect signs included (1) cystic cerebrospinal fluid gathering in the vertebral canal, posttraumatic spinal meningocele in 46 pairs (73.0%), (2) abnormal shape of nerve sleeve in 13 pairs (20.6%), (3) displacement and deformity of spinal cord in 50 pairs (79.4%), (4) abnormal signal of paravertebral muscles in 19 patients. Conclusion: MRI can distinctly show the nerve rootlets within the vertebral canal, so it is helpful in making a correct diagnosis of brachial plexus preganglionic injuries. (authors)

    2016-01-01

    With advances in implant technology, total ankle arthroplasty (TAA) has become an increasingly popular alternative to arthrodesis for the management of end-stage ankle arthritis. However, reports in the literature do not focus on the imaging features of TAA. Through a literature review, we demonstrate basic design features of the current ankle arthroplasty system, and the normal and abnormal postoperative imaging features associated with such devices. Pre- and postoperative evaluations of ankle arthroplasty mainly include radiography; in addition, computed tomography and magnetic resonance imaging provide further characterization of imaging abnormalities. Familiarization with multimodal imaging features of frequent procedural complications at various postoperative intervals is important in radiological practice. PMID:27134529

  16. MR Imaging of Ankle Impingement Syndromes

    Seyed Hassan Mostafavi

    2010-05-01

    Full Text Available Ankle impingement syndromes are characterized by painful friction of joint tissues. This is both the cause and the effect of altered joint biomechanics. The leading causes of impingement lesions are posttraumatic ankle injuries, usually ankle sprains, resulting in chronic ankle pain. "nBased on anatomic and clinical viewpoints, there are five types of ankle impingement syndromes:"n1. Anterolateral"n2. Anterior"n3. Anteromedial"n4. Posteromedial"n5. Posterior"nCareful analyses of patient history and signs and symptoms at physical examination can suggest a specific diagnosis in most patients. MR imaging and MR arthrography are the most useful imaging methods for detecting the osseous and soft-tissue abnormalities present in these syndromes and for ruling out other potential causes of chronic ankle pain. "nThis presentation summarizes the MR imaging, and MR arthrography findings of ankle impingement syndromes.

    Struijs, Peter AA; Kerkhoffs, Gino MMJ

    2010-01-01

    Injury of the lateral ligament complex of the ankle joint occurs in about one in 10,000 people a day, accounting for a quarter of all sports injuries. Pain may be localised to the lateral side of the ankle.Residual complaints include joint instability, stiffness, and intermittent swelling, and are more likely to occur after more extensive cartilage damage.Recurrent sprains can add new damage and increase the risk of long-term degeneration of the joint.

  20. MR evaluation of brachial plexus injuries

    Ten cases of brachial plexus injury were subjected to magnetic resonance (MR) to demonstrate the roots, trunks, divisions or cord abnormalities. Both normal and abnormal brachial plexuses were imaged in sagittal, axial, coronal and axial oblique planes. Myelography, using water soluble contrast agents, was performed in seven cases. MR demonstrated one traumatic meningocele, one extradural cerebrospinal fluid (CSF) collection, trunk and/or root neuromas in four, focal root fibrosis in two and diffuse fibrosis in the remaining two cases. Results of MR were confirmed at surgery in four cases with neuromas, while myelography was normal in two and was not carried out in the remaining two. In two cases, where MR demonstrated diffuse fibrosis of the brachial plexus, myelography showed C7 and T1 traumatic meningocele in one and was normal in the other. Both these patients showed excellent clinical and electrophysiological correlation with MR findings and in one of them surgical confirmation was also obtained. In the other two cases with focal nerve root fibrosis, myelography was normal in one and showed a traumatic meningocele in another. Operative findings in these cases confirmed focal root fibrosis but no root avulsion was observed although seen on one myelogram. Focal fibrosis, however, was noted at operation in more roots than was observed with MR. Initial experience suggests that MR may be the diagnostic procedure of choice for complete evaluation of brachial plexus injuries. (orig.)

  1. Acute inversion injury of the ankle without radiological abnormalities: assessment with high-field MR imaging and correlation of findings with clinical outcome

    Acute inversion injuries of the ankle are the most common sports accidents, accounting for approximately 10% of emergency room admissions. In up to 85%, an injury of the lateral collateral ligaments is observed. Classically, the assessment of these injuries has relied on clinical examination and radiographs, including stress views. The aim of our study was to correlate prospectively the findings of high-field 3 T MRI in acute ankle distortion with clinical outcome. During a 6-month period, 38 patients were prospectively included. MRI was performed within 48 h of trauma and clinical examination using a protocol consisting of axial T2-weighted and coronal and sagittal T1-weighted images and a sagittal proton density (PDw) sequence. Each ligament injury was graded on a three-point scale. Functional outcome was evaluated using the AOFAS ankle-hindfoot scale. In 24/38 patients (63.12%), ligament injury was observed. In 22/24 cases, this was an injury of the lateral ligaments and in 2/24 cases of the medial ligaments. Injury of the syndesmosis occurred in three patients, a bone bruise in four, and an osteochondral lesion in three cases. Patients with an injury of two or more ligaments or a bone bruise had a lower AOFAS score and returned to sports activities and full weight-bearing later (P < 0.01). MR imaging at 3 Tesla is an independent predictor for clinical outcome. Therefore MRI may be beneficial in those cases where the findings influence further treatment. (orig.)

    Hubka, Michael J; King, Laurie; Cassidy, J. David; Donat, JR

    1992-01-01

    Branchial plexus neuropathy is characterized by acute onset of intense pain in the shoulder or arm followed shortly by focal muscle weakness. This presentation may mislead the clinician into diagnosing shoulder or cervical spine pathology. Although brachial plexus neuropathy is not common, it should be considered in the differential diagnosis of pain and weakness of the arm. We present a patient with brachial plexus neuropathy who was originally misdiagnosed as having a cervical disc herniation.

  4. Surgical treatment of the arthritic varus ankle.

    Easley, Mark E

    2012-12-01

    Within the past several years, the arthritic varus ankle has been addressed extensively in Foot and Ankle Clinics, with numerous excellent reviews by particularly knowledgeable authors. To support these outstanding contributions, this article provides a practical approach to this challenging constellation of foot and ankle abnormalities. Varus ankle arthritis exists on a continuum that prompts the treating surgeon to be familiar with a spectrum of surgical solutions, including joint-sparing realignment, arthroplasty, and arthrodesis. Each of these treatment options is addressed with several expanded case examples and supports the management approaches with the available pertinent literature. PMID:23158376

  8. Ankle impingement syndromes

    Soft-tissue and osseous impingement syndromes can be an important cause of chronic ankle pain, particularly in the professional athlete. The classification of ankle impingement syndromes is based to their anatomical location around the tibiotalar joint. The most important impingement syndromes are anterolateral, anterior and posterior impingement with more recent studies describing posteromedial and anteromedial impingement. Usually conventional radiography is the first imaging technique to be performed as it allows assessment of potential bone abnormalities, particularly in anterior and posterior joint compartments. Computed tomography (CT) only plays a role in the assessment of the posterior impingement. Magnetic resonance (MR) imaging is regarded as the modality of choice as it is able to demonstrate both osseous and soft tissue changes, such as bone marrow edema, capsular and ligametous thickening, and localized synovitis.

    2010-12-01

    Full Text Available Abstract Background The Ankle Brachial Index is a useful clinical test for establishing blood supply to the foot. However, there are limitations to this method when conducted on people with diabetes. As an alternative to the Ankle Brachial Index, measuring Toe Systolic Pressures and the Toe Brachial Index have been recommended to assess the arterial blood supply to the foot. This study aimed to determine the intra and inter-rater reliability of the measurement of Toe Systolic Pressure and the Toe Brachial Index in patients with diabetes using a manual measurement system. Methods This was a repeated measures, reliability study. Three raters measured Toe Systolic Pressure and the Toe Brachial Index in thirty participants with diabetes. Measurement sessions occurred on two occasions, one week apart, using a manual photoplethysmography unit (Hadeco Smartdop 45 and a standardised measurement protocol. Results The mean intra-class correlation for intra-rater reliability for toe systolic pressures was 0.87 (95% LOA: -25.97 to 26.06 mmHg and the mean intra-class correlation for Toe Brachial Indices was 0.75 (95% LOA: -0.22 to 0.28. The intra-class correlation for inter-rater reliability was 0.88 for toe systolic pressures (95% LOA: -22.91 to 29.17.mmHg and 0.77 for Toe Brachial Indices (95% LOA: -0.21 to 0.22. Conclusion Despite the reasonable intra-class correlation results, the range of error (95% LOA was broad. This raises questions regarding the reliability of using a manual sphygmomanometer and PPG for the Toe Systolic Pressure and Toe Brachial Indice.

    Pre-operative US examinations of the brachial plexus were performed with the purpose of exploring the potential of this technique in recognizing lesions in the region and defining their sonographic morphology, site, extent, and relations to adjacent anatomic structures, and comparing them to the surgical findings to obtain maximal confirmation. Twenty-eight patients with clinical, electro-conductive, and imaging findings suggestive of brachial plexus pathology were included in this study. There were four main etiology groups: post-traumatic brachial plexopathies; primary tumors (benign and malignant); secondary tumors; and post irradiation injuries. Twenty-one of the 28 patients underwent surgery. Advanced imaging (mostly MRI) served as an alternative gold standard for confirmation of the findings in the non-surgically treated group of patients. The US examinations were performed with conventional US units operating at 5- to 10-MHz frequencies. The nerves were initially localized at the level of the vertebral foramina and then were followed longitudinally and axially down to the axillary region. Abnormal US findings were detected in 20 of 28 patients. Disruption of nerve continuity and focal scar tissue masses were the principal findings in the post-traumatic cases. Focal masses within a nerve or adjacent to it and diffuse thickening of the nerve were the findings in primary and secondary tumors. Post-irradiation changes presented as nerve thickening. Color Doppler was useful in detecting internal vascularization within masses and relation of a mass to adjacent vessels. The eight sonographically negative cases consisted either of traumatic neuromas smaller than 12 mm in size and located in relatively small branches of posterior location or due to fibrotic changes of diffuse nature. Sonography succeeded in depicting a spectrum of lesions of traumatic, neoplastic, and inflammatory nature in the brachial plexus. It provided useful information regarding the lesion site

Its onset is characterized by acute, aching shoulder pain lasting a few days to weeks, followed by progressive shoulder girdle and upper extremity weakness and atrophy, with a slow but progressive recovery of motor function over 6 to 18 months. Its early recognition can help avoid unnecessary and potentially h...

  19. Obstetric brachial plexus injury

    Mukund R Thatte

    2011-01-01

    Full Text Available Obstetric brachial plexus injury (OBPI, also known as birth brachial plexus injury (BBPI, is unfortunately a rather common injury in newborn children. Incidence varies between 0.15 and 3 per 1000 live births in various series and countries. Although spontaneous recovery is known, there is a large subset which does not recover and needs primary or secondary surgical intervention. An extensive review of peer-reviewed publications has been done in this study, including clinical papers, review articles and systematic review of the subject. In addition, the authors′ experience of several hundred cases over the last 15 years has been added and has influenced the ultimate text. Causes of OBPI, indications of primary nerve surgery and secondary reconstruction of shoulder, etc. are discussed in detail. Although all affected children do not require surgery in infancy, a substantial proportion of them, however, require it and are better off for it. Secondary surgery is needed for shoulder elbow and hand problems. Results of nerve surgery are very encouraging. Children with OBPI should be seen early by a hand surgeon dealing with brachial plexus injuries. Good results are possible with early and appropriate intervention even in severe cases.

    Injury to the brachial plexus in the adult is usually a closed injury and the result of considerable traction to the shoulder. Brachial plexus injury in the adult is an increasingly common clinical problem. Recent advances in neurosurgical techniques have improved the outlook for patients with brachial plexus injuries. The choice of surgical procedure depends on the level of the injury and the radiologist has an important role in guiding the surgeon to the site of injury. This article will describe the anatomy and pathophysiology of traction brachial plexus injury in the adult. The neurosurgical options available will be described with emphasis on the information that the surgeon wants from imaging studies of the brachial plexus. The relative merits of MRI and CT myelography are discussed.

Method: The study population consisted of 120 patients scheduled to undergo elective cardiac catheterization for suspected CAD (from September 2010 to December). Collected data included ABI and hs-CRP before underwent coronary angiography. According to the degree of coronary stenosis (estimated by Gensini score) and the number of coronary artery stenosis, all subjects were divided into different groups. Result: With ABI 3 mg/L as the cutoff value, combined the 2 methods to predict serious stenosis and multi-vessel CAD, the sensitivity was respectively 85%, 92%, and the specificity was respectively 69%, 61%. Compared with using ABI or hs-CRP alone, the sensitivity of the 2 joint detection for predicting CAD increased significantly (P<0. 05); the specificity decreased, but the difference was not statistically significant. Conclusion: ABI and hs-CRP are closely related to the extent of coronary artery disease, and the combination of ABI and hs-CRP may have higher practical value for

    Magnetic resonance (MR) neurography comprises an evolving group of techniques with the potential to allow optimal noninvasive evaluation of many abnormalities of the brachial plexus. MR neurography is clinically useful in the evaluation of suspected brachial plexus traumatic injuries, intrinsic and extrinsic tumors, and post-radiogenic inflammation, and can be particularly beneficial in pediatric patients with obstetric trauma to the brachial plexus. The most common MR neurographic techniques for displaying the brachial plexus can be divided into two categories: structural MR neurography; and microstructural MR neurography. Structural MR neurography uses mainly the STIR sequence to image the nerves of the brachial plexus, can be performed in 2D or 3D mode, and the 2D sequence can be repeated in different planes. Microstructural MR neurography depends on the diffusion tensor imaging that provides quantitative information about the degree and direction of water diffusion within the nerves of the brachial plexus, as well as on tractography to visualize the white matter tracts and to characterize their integrity. The successful evaluation of the brachial plexus requires the implementation of appropriate techniques and familiarity with the pathologies that might involve the brachial plexus.

  8. Avulsion of the brachial plexus in a great horned owl (Bubo virginaus)

    Moore, M.P.; Stauber, E.; Thomas, N.J.

    1989-01-01

    Avulsion of the brachial plexus was documented in a Great Horned Owl (Bubo virginianus). A fractured scapula was also present. Cause of these injuries was not known but was thought to be due to trauma. Differentiation of musculoskeletal injury from peripheral nerve damage can be difficult in raptors. Use of electromyography and motor nerve conduction velocity was helpful in demonstrating peripheral nerve involvement. A brachial plexus avulsion was suspected on the basis of clinical signs, presence of electromyographic abnormalities in all muscles supplied by the nerves of the brachial plexus and absence of median-ulnar motor nerve conduction velocities.

  15. MR imaging of brachial plexus

    The brachial plexus is a difficult region to evaluate with radiological techniques. MR imaging has great potentials for the depiction of the various anatomical structures of the branchial plexus - i.e., spinal ganglion, ventral nerve rami root exit of the neural foramina, trunks an cordes. Moreover, MR imaging, thanks to its direct multiplanarity, to its excellent soft-tissue contrast, and to its lack of motion artifacts, allows good evaluation of pathologic conditions in the branchial plexus, especially traumas and cancers. On the contrary CT, in spite of its high spatial resolution and good contrast, cannot demonstrate the anatomical structures of the brachial plexus. US detects superficials structures, and conventional radiographs depict only indirect changes in the adjacent lung apex and skeletal structures. From November 1989 to May 1990, 20 normal volunteers (15 males and 5 females; average age: 35 years) were studied with MR imaging. Multisection technique was employed with a dedicated coil and a primary coil. The anatomical structures of the brachial plexus were clearly demonstrated by T1-weighted sequences on the sagittal and axial planes. T2-weighted pulse sequences on the coronal plane were useful for the anatomical definition of the brachial plexus and for eventual tissue characterization. The correct representation of the anatomical structures of the brachial plexus allowed by MR imaging with author's standard technique makes MR imaging the most appropriate exam for the diagnosis of pathologic conditions in the brachial plexus, although its use must be suggested by specific clinical questions

For people with end-stage ankle arthritis, arthrodesis (ankle fusion) is effective at reducing pain in the shorter term, but results in a fixed joint, and over time the loss of mobility places stress on other joints in the foot that may lead to arthritis, pain and dysfunction. Another option is to perform a total ankle joint replacement, with the aim of giving the patient a mobile and pain-free ankle. In this article we review the efficacy of this procedure, including how it compares to ankle arthrodesis, and consider the indications and complications. PMID:26868932

    True upper extremity peripheral artery aneurysms are a rarely encountered arterial disorder. Following computer-tomography angiographic (CT-a) imaging examination, true saccular aneurysm, originating from the left brachial artery was diagnosed in the 77-year-old female without history of trauma. The aneurysm was resected by surgical intervention, and primary repair of the brachial artery was performed by interposition of a part of great saphenous vein harvested from the left groin and creation of two end-to-end anastomoses between interposition graft and previously resected part of brachial artery. No complication was observed during the follow-up. Surgical intervention for upper extremity aneurysms should be initiated without delay. Factors combined with minimal morbidity associated with repair suggest that surgical repair should be performed routinely for true upper extremity arterial aneurysms. PMID:20865459

    Objective. To investigate the role of MR imaging in detecting brachial plexus (BP) abnormalities in breast cancer patients with plexopathy but without palpable masses.Design. MR imaging of the BP was performed on 26 breast cancer patients with brachial plexopathy without palpable regional masses, using 0.5 T and 1.5 T imaging systems. Findings were correlated with the clinical diagnoses.Patients. Twenty-six patients with brachial plexopathy and history of breast cancer were enrolled in the study. All patients presented with plexopathy symptoms. Fourteen patients were positive and 12 patients were indeterminate for BP metastasis according to clinical criteria.Results and conclusion. MR imaging demonstrated masses involving the BP representing metastases in two patients. Nine patients had other regional abnormalities with a normal brachial plexus. It is concluded that MR imaging is useful in the assessment and direction of therapy of brachial plexopathy in breast cancer patients by detecting both metastases to the BP as well as other abnormalities, unrelated to the BP, which may explain the patient's symptoms.

    Full Text Available An experiment was designed to determine if KinesioTM taping the anterior and lateral portion of the ankle would enhance ankle proprioception compared to the untaped ankle. 30 subjects, 15 men, 15 women, ages 18-30 participated in this study. Exclusion criteria: Ankle injury < 6 months prior to testing, significant ligament laxity as determined through clinical evaluation by an ATC, or any severe foot abnormality. Experiment utilized a single group, pretest and posttest. Plantar flexion and inversion with 20° of plantar flexion reproduction of joint position sense (RJPS was determined using an ankle RJPS apparatus. Subjects were barefooted, blindfolded, and equipped with headphones playing white noise to eliminate auditory cues. Subjects had five trials in both plantar flexion and inversion with 20° plantar flexion before and after application of the KinesioTM tape to the anterior/lateral portion of the ankle. Constant error and absolute error were determined from the difference between the target angle and the trial angle produced by the subject. The treatment group (KinesioTM taped subjects showed no change in constant and absolute error for ankle RJPS in plantar flexion and 20º of plantar flexion with inversion when compared to the untaped results using the same motions. The application of KinesioTM tape does not appear to enhance proprioception (in terms of RJPS in healthy individuals as determined by our measures of RJPS at the ankle in the motions of plantar flexion and 20º of plantar flexion with inversion.

    Anterior ankle impingement results from an impingement of the ankle joint by a soft tissue or osteophyte formation at the anterior aspect of the distal tibia and talar neck. It often occurs secondary to direct trauma (impaction force) or repetitive ankle dorsiflexion (repetitive impaction and traction force). Chronic ankle pain, swelling, and limitation of ankle dorsiflexion are common complaints. Imaging is valuable for diagnosis of the bony impingement but not for the soft tissue impingemen...

  7. Arthrography of the ankle

    As part of a clinical prospective investigation 102 patients with fresh ankle injuries underwent ankle arthrography and surgery for rupture of the lateral ligaments of the ankle. Three hypotheses concerning the improvement of the arthrographic diagnosis of rupture of the calcaneofibular ligament were tested. Two were rejected. Improvement in the diagnostic specificity was possible by combining arthrography with a stress inversion test, but the sensitivity of this combination was low. It was demonstrated that absence of peroneus sheath filling was a better diagnostic sign with good rather than with poor recess filling. (Auth.)

    2007-01-01

    OBJECTIVE: To sum up the treatment of brachial plexus root avulsion and the progress in functional reconstruction and rehabilitation following brachial plexus root avulsion.DATA SOURCES: A search of Medline was performed to select functional reconstruction and rehabilitation following brachial plexus injury-related English articles published between January 1990 and July 2006, with key words of "brachial plexus injury, reconstruction and rehabilitation". Meanwhile, a computer-based search of CBM was carried out to select the similar Chinese articles published between January 1998 and July 2006,with key words of "brachial plexus injury, reconstruction and rehabilitation".STUDY SELECTION: The materials were checked primarily, and the literatures of functional reconstruction and rehabilitation of brachial plexus injury were selected and the full texts were retrieved.Inclusive criteria: ① Functional reconstruction following brachial plexus injury. ② Rehabilitation method of brachial plexus injury. Exclusive criteria: Reviews, repetitive study, and Meta analytical papers.DATA EXTRACTION: Forty-six literatures about functional reconstruction following brachial plexus injury were collected, and 36 of them met the inclusive criteria.DATA SYNTHESIS: Brachial plexus injury causes the complete or incomplete palsy of muscle of upper extremity. The treatment of brachial plexus is to displace not very important nerves to the distal end of very important nerve, called nerve transfer, which is an important method to treat brachial plexus injury.Postoperative rehabilitations consist of sensory training and motor functional training. It is very important to keep the initiativeness of exercise. Besides recovering peripheral nerve continuity by operation, combined treatment and accelerating neural regeneration, active motors of cerebral cortex is also the important factor to reconstruct peripheral nerve function.CONCLUSION: Consciously and actively strengthening functional

  12. Cervical myelographic findings of brachial plexus injury by trauma

    Authors reviewed 50 cases of cervical myelography during 4 years and 5 months, from February, 1985 to July, 1989 at Department of Radiography, Wonkwang University Hospital to analyse myelographic findings of traumatic brachial plexus injury with symptoms and signs and to discuss literature. The results were as follows: 1. Brachial plexus injury was predominant in male and the incidence was 50% in 3rd decade of the males. 2. Among the 50 patients, 11 were the peripheral type, which had symptoms but normal findings in cervical myelography and 39 were the central type, which were definitely abnormal findings in cervical myelography. 3. Cervical myelographic findings in the central type were divided into 5 groups. (all 39 cases) a. Obliteration of nerve root filling defect 39(cases) b. Pseudomeningocele. 32(cases) c. Narrowing of ipsilateral subarachnoid space 31(cases) d. Diverticulum. 4 (cases) e. Tracking of dye down the axillary sheath 1 (cases) 4. The most large numbers of pseudomeningoceles in cervical myelography were shown for two and in each case, the most multiple developing numbers of pseudomeningoceles were identified for four, that happened in one case. 5. In brachial plexus injury, there were two the most large involving numbers among the nerve roots, and in each involving nerve root, C7 was most common

  13. MR neurography of the brachial plexus

    Magnetic resonance neurography was used to directly image the brachial plexus in patients with clinically suspected brachial plexus neuritis. The authors obtained spectral presaturation with inversion recovery and short T1 inversion recovery images parallel to the long axis of nerves using neurovascular array coils in 17 patients. In seven patients, the images revealed nerve swelling and hyperintensity in the the brachial plexus. In three patients with zoster paresis of the shoulder or upper extremity the images revealed marked hyperintensity in the roots. Direct nerve imaging may prove to be helpful in evaluating patients with brachial plexus neuritis. (author)

  14. Ankle injuries in basketball players.

    Leanderson, J; Nemeth, G; Eriksson, E

    1993-01-01

    We carried out a retrospective study of the frequency of ankle sprains in basketball players. A questionnaire about previous ankle injuries, time off after such injuries, current ankle problems, personal data, number of practice hours and the use of prophylactic measures was sent out to 102 basketball players in a second division league in Sweden. Ninety-six players answered. 92% of them had suffered an ankle sprain while playing basketball, and of these 83% reported repeated sprains of one ankle. In the last two seasons, 78% of the players had injured at least one ankle. The injury frequency in the investigation was 5.5 ankle injuries per 1000 activity hours. 22% of the players used some kind of prophylactic support of their ankle joints. Because of the great number of ankle sprains and the disability in terms of time away from sports that they cause, prevention of these injuries is essential. PMID:8536029

  16. CT scanning of the brachial plexus, normal anatomy, pathology, and radiation fibrosis

    The brachial plexus is a region difficult to examine clinically and by conventional radiology. CT is ideally suited to image this area, and detailed anatomy of the plexus can be visualized. Sixty patients with brachial plexus symptoms underwent CT of the root of the neck and axilla. Forty-two of these had previously been treated with radiation therapy for carcinoma of the breast. CT was a sensitive modality for demonstrating abnormalities in this region, and radiation fibrosis could be differentiated from recurrent axillary disease. A greater degree of fibrosis did not correlate with different treatment schedules but with a higher fraction size

  17. Ankle ligament injuries

    Per A.F.H. Renström

    1998-06-01

    Full Text Available Acute ankle ligament sprains are common injuries. The majority of these occur during athletic participation in the 15 to 35 year age range. Despite the frequency of the injury, diagnostic and treatment protocols have varied greatly. Lateral ligament complex injuries are by far the most common of the ankle sprains. Lateral ligament injuries typically occur during plantar flexion and inversion, which is the position of maximum stress on the anterotalofibular liagment (ATFL. For this reason, the ATFL is the most commonly torn ligament during an inversion injury. In more severe inversion injuries the calcaneofibular (CFL, posterotalofibular (PTFL and subtalar ligament can also be injured. Most acute lateral ankle ligament injuries recover quickly with nonoperative management. The treatment program, called "functional treatment," includes application of the RICE principle (rest, ice, compression, and elevation immediately after the injury, a short period of immobilization and protection with an elastic or inelastic tape or bandage, and early motion exercises followed by early weight bearing and neuromuscular ankle training. Proprioceptive training with a tilt board is commenced as soon as possible, usually after 3 to 4 weeks. The purpose is to improve the balance and neuromuscular control of the ankle. Sequelae after ankle ligament injuries are very common. As much as 10% to 30% of patients with a lateral ligament injury may have chronic symptoms. Symptoms usually include persistent synovitis or tendinitis, ankle stiffness, swelling, and pain, muscle weakness, and frequent giving-way. A well designed physical therapy program with peroneal strengthening and proprioceptive training, along with bracing and/or taping can alleviate instability problems in most patients. For cases of chronic instability that are refractory to bracing and external support, surgical treatment can be explored. If the chronic instability is associated with subtalar instability

    2014-10-01

    Ankle sprains constitute the majority of ankle injuries, and result in pain, limited mobility/exercise and loss of school/work days. Ankle sprains involve at least one of the ankle ligaments and range from a micro tear to complete tear of the ligament or group of ligaments. The most common mechanism of ankle sprains is inversion stress of a plantar-flexed foot, while the most frequently injured ligament is the anterior talofibular ligament. The attending clinician needs to stratify the risk of fracture through history-taking and physical examination, manage the pain, assess long‑term complications and provide certification for rest and recovery. The Ottawa ankle rules may be useful. Graduated exercises to maintain the ankle's range of motion should be started early, after the resolution of initial pain and swelling. The risk of recurrent ankle injuries is often a combination of both mechanical and functional disabilities. PMID:25631892

  3. Brachial neuritis following a corticosteroid injection.

    Robinson, Matthew; Fulcher, Mark

    2014-01-01

    This report presents a case of brachial neuritis following a subacromial corticosteroid injection. The patient developed an anterior interosseous neuropathy shortly after the injection, with no other trigger being identified. This neuropathy has unfortunately not shown any sign of recovery at 2 years. The authors propose that corticosteroid injection be added to the list of possible triggering events of brachial neuritis and highlight the frequent use of oral corticosteroids in its treatment. (1) The injection of local anaesthetic and corticosteroid should be considered as a potential trigger for brachial neuritis. (2) Brachial neuritis should be considered in the differential diagnosis for patients presenting with severe arm pain and weakness. (3) The nerves originating from the upper trunk of the brachial plexus are most commonly affected. (4) The anterior interosseous nerve is involved in one-third of cases.

  6. Traumatic injuries of brachial plexus

    The authors report their experience in 144 patients with traumatic brachial plexus injury who underwent Direct Cervical Myelography (DCM). Sometimes the diagnostic investigation was completed by CT. Various myelographic patterns are described: pseudomeningocele, missing sheet of the root, scarring lesions. In 9 cases only, myelography was not sufficient to provide a complete diagnosis. The examination showed all plexus roots lacerated in 14 patients, a monoradicular lesion in 75 cases, and no lesion in 26 cases. Twenty-one out of the 26 negative cases were confirmed during surgery, while in 2 patients an intracanalar injury was found, which had not been detected due to the presence of scars. Scars often compress healty roots, and may mask intracanalar injuries. In such cases, and when the spinal cord stretches towards the side of the lesion, Myelo-CT can be useful. DCM proved to be an extremely sensitive and specific method, which can be used as a first-choice radiological procedure in the study of traumatic injuries of the brachial plexus

    Magnetic resonance neurography (MRN) enables visualization of peripheral nerves. Clinical examination and electrodiagnostic studies have been used in the evaluation of birth-related brachial plexus injury. These are limited in their demonstration of anatomic detail and severity of injury. We investigated the utility of MRN in evaluating birth-related brachial plexus injury in pediatric patients, and assessed the degree of correlation between MRN findings and physical examination and electromyographic (EMG) findings. The MRN findings in 11 infants (age 2 months to 20 months) with birth-related brachial plexus injury were evaluated. A neuroradiologist blinded to the EMG and clinical examination findings reviewed the images. Clinical history, examination, EMG and operative findings were obtained. All infants had abnormal imaging findings on the affected side: seven pseudomeningoceles, six neuromas, seven abnormal nerve T2 signal, four nerve root enlargement, and two denervation changes. There was greater degree of correlation between MRN and physical examination findings (kappa 0.6715, coefficient of correlation 0.7110, P < 0.001) than between EMG and physical examination findings (kappa 0.5748, coefficient of correlation 0.5883, P = 0.0012). MRN in brachial plexus trauma enables localization of injured nerves and characterization of associated pathology. MRN findings demonstrated a statistically significant correlation with physical examination and EMG findings, and might be a useful adjunct in treatment planning. (orig.)

    Forte, A; Gallinaro, L S; Bertagni, A; Montesano, G; Prece, V; Illuminati, G

    1999-01-01

    Neurinomas, also referred to as neurilemmomas and schwannomas, are rare benign tumours of the peripheral nerves, a low proportion of which arise from the brachial plexus. Authors report a case of an ancient schwannoma arising from the brachial plexus. The tumour, usually asymptomatic, may cause sensory radicular symptoms, or rarely motor deficits in the involved arm. Enucleation of the tumour from the nerve without damage to any of the fascicles is the correct treatment. PMID:10710825

  19. Arthrography of the ankle

    Arthrography was performed in 105 cases with freshly sprained ankles and signs of rupture of the anterior talofibular ligament. They were subsequently operated upon. The arthrographic films were examined retrospectively to assess the value of different criteria for the differential diagnosis between rupture of the anterior talofibular ligament and combined rupture of this and the calcaneofibular ligament. The diagnostic value of arthrography was found to be high in isolated rupture of the anterior talofibular ligament, and is acceptable in the combined ruptures. (Auth.)

  20. Update on acute ankle sprains.

    Tiemstra, Jeffrey D

    2012-06-15

    Ankle sprains are a common problem seen by primary care physicians, especially among teenagers and young adults. Most ankle sprains are inversion injuries to the lateral ankle ligaments, although high sprains representing damage to the tibiofibular syndesmosis are becoming increasingly recognized. Physicians should apply the Ottawa ankle rules to determine whether radiography is needed. According to the Ottawa criteria, radiography is indicated if there is pain in the malleolar or midfoot zone, and either bone tenderness over an area of potential fracture (i.e., lateral malleolus, medial malleolus, base of fifth metatarsal, or navicular bone) or an inability to bear weight for four steps immediately after the injury and in the emergency department or physician's office. Patients with ankle sprain should use cryotherapy for the first three to seven days to reduce pain and improve recovery time. Patients should wear a lace-up ankle support or an air stirrup brace combined with an elastic compression wrap to reduce swelling and pain, speed recovery, and protect the injured ligaments as they become more mobile. Early mobilization speeds healing and reduces pain more effectively than prolonged rest. Pain control options for patients with ankle sprain include nonsteroidal anti-inflammatory drugs, acetaminophen, and mild opioids. Because a previous ankle sprain is the greatest risk factor for an acute ankle sprain, recovering patients should be counseled on prevention strategies. Ankle braces and supports, ankle taping, a focused neuromuscular training program, and regular sport-specific warm-up exercises can protect against ankle injuries, and should be considered for patients returning to sports or other high-risk activities.

  1. MR imaging of the ankle

    To define the clinical role of MRI of the ankle joint, a total of 98 patients were investigated. In the evaluation of ligamentous injuy, MRI was inferior to established imaging methods. By contrast, it provided additional therapy-relevant information in the assessment of hemophilic arthropathy, osteochondritis dissecans, and inflammatory and neoplastic diseases of the ankle joint. In the latter conditions, MRI may make other more conventional methods of examining the ankle joint unnecessary. (orig.)

    2013-01-01

    Ankle syndesmosis injuries are relatively frequent in sports, especially skiing, ice hockey, and soccer, accounting for 1 %–18 % of all ankle sprains. The evolution is unpredictable: When missed, repeated episodes of ankle instability may predispose to early degenerative changes, and frank osteoarthritis may ensue. Diagnosis is clinical and radiological, but arthroscopy may provide a definitive response, allowing one to address secondary injuries to bone and cartilage. Obvious diastasis needs...

  4. Perspectives on glenohumeral joint contractures and shoulder dysfunction in children with perinatal brachial plexus palsy.

    Gharbaoui, Idris S; Gogola, Gloria R; Aaron, Dorit H; Kozin, Scott H

    2015-01-01

    Shoulder joint deformities continue to be a challenging aspect of treating upper plexus lesions in children with perinatal brachial plexus palsy (PBPP). It is increasingly recognized that PBPP affects the glenohumeral joint specifically, and that abnormal scapulothoracic movements are a compensatory development. The pathophysiology and assessment of glenohumeral joint contractures, the progression of scapular dyskinesia and skeletal dysplasia, and current shoulder imaging techniques are reviewed.

  5. Acute ankle sprain: an update.

    Ivins, Douglas

    2006-11-15

    Acute ankle injury, a common musculoskeletal injury, can cause ankle sprains. Some evidence suggests that previous injuries or limited joint flexibility may contribute to ankle sprains. The initial assessment of an acute ankle injury should include questions about the timing and mechanism of the injury. The Ottawa Ankle and Foot Rules provide clinical guidelines for excluding a fracture in adults and children and determining if radiography is indicated at the time of injury. Reexamination three to five days after injury, when pain and swelling have improved, may help with the diagnosis. Therapy for ankle sprains focuses on controlling pain and swelling. PRICE (Protection, Rest, Ice, Compression, and Elevation) is a well-established protocol for the treatment of ankle injury. There is some evidence that applying ice and using nonsteroidal antiinflammatory drugs improves healing and speeds recovery. Functional rehabilitation (e.g., motion restoration and strengthening exercises) is preferred over immobilization. Superiority of surgical repair versus functional rehabilitation for severe lateral ligament rupture is controversial. Treatment using semirigid supports is superior to using elastic bandages. Support devices provide some protection against future ankle sprains, particularly in persons with a history of recurrent sprains. Ankle disk or proprioceptive neuromuscular facilitation exercise regimens also may be helpful, although the literature supporting this is limited. PMID:17137000

  6. Talofibular compartment of the ankle joint after recent ankle sprain

  7. Role of endothelin receptor A and NADPH oxidase in vascular abnormalities

    De-Zai Dai

    2010-09-01

    Full Text Available De-Zai Dai, Yin DaiResearch Division of Pharmacology, China Pharmaceutical University, Nanjing, 210009, ChinaAbstract: Vascular dilatation is critically impaired in many diseases and is encountered by an upregulated endothelin receptor A (ETA in the vasculature in association with a decline in nitric oxide bioavailability. Diabetic vasculopathy is characterized as a compromised vascular dilatation, implicated in many diabetic complications. It appears to be activated ETA and NADPH (­nicotinamide adenine dinucleotide phosphate oxidase in the vasculature. Glucose-lowering agents do not always blunt these changes, as these changes may be progressive leading to the end stage of renal disease. The vascular insults by hypertension, hyperglycemia and aging may share the changes with diabetic vascular beds. Endothelin receptor antagonist CPU0213 and ingredients from plant origins such as CPU86017, p-benzyl-tetra-hydro-berberine are effective in attenuating vascular abnormality by normalizing changes of biomarkers in the ­vascular wall. The early sign of subclinical atherosclerosis presented as an intima media thickness in the carotid may indicate endothelium dysfunction. The reduced ABI (ankle brachial index has been taken to predict patients at risk for cardiovascular and cerebrovascular events, and an increased risk of mortality from all causes and cardiovascular disease. An application of agents which ­suppress the activated ET-NADPH oxidase in the vascular wall is beneficial to attenuate vascular abnormalities. It is worth testing the activity of these agents further for the potential in relieving abnormal vascular activity, reducing the risk of morbidity and mortality in patients at risk.Keywords: diabetes, hypercholesterolemia, ETA, peripheral artery disease, vascular dilatation

    2011-01-01

    Brachial plexus birth injuries in children are usually diagnosed using 1.5-T magnetic resonance imaging, while the application of high-field magnetic resonance imaging is rarely reported. Therefore, a retrospective comparison of 18 cases of children with brachial plexus injury was performed to investigate the characteristics of 3.0-T magnetic resonance imaging and intraoperative observations. Magnetic resonance examinations in 18 cases of children showed that pseudo-meningocele sensitivity, specificity, accuracy, and positivity rates were 83.3%, 79.6%, 81.1%, and 40.0%, respectively. As for the neuroma and fibrous scar encapsulation, the sensitivity, specificity, accuracy, and positivity rates were 92.9%, 50.0%, 83.3%, and 77.8%, respectively. These results confirm that 3.0-T high-field magnetic resonance imaging can clearly reveal abnormal changes in brachial plexus injury, in which pseudo-meningocele, fibrous scar encapsulation, and neuroma are the characteristic changes of obstetric brachial plexus preganglionic and postganglionic nerve injury.

  9. Radiology of chronic diseases of the ankle joint

    The etiology of chronic diseases of the ankle joint comprises a wide spectrum including chronic inflammatory processes and chronic degenerative, tumorous and neuropathic processes, as well as some specific syndromes based on chronic changes of the ankle joint. Of the inflammatory processes, chronic juvenile arthritis (JVC) is the most common disease. However, also Reiter disease, psoriasis or chronic monoarthritid diseases such as gout, as well as granulomatous diseases (tuberculosis, sarcoidosis) and fungal infections, may affect the ankle joint in a chronic course. Chronic degenerative changes are usually secondary due to abnormal positioning of the joint constituents or repetitive trauma. Neuropathic changes, as frequently seen in the course of diabetes, present with massive osseous destruction and malposition of the articular constituents. Chronic osseous as well as cartilaginous and synovial changes are seen in hemoplici patients. Chronic traumatic changes are represented by pigmented villonodular synovitis (PVNS), and chondromatosis, both with a predilection for the ankle joint. Due to the possibilities of magnetic resonance imaging (MRI), diagnosis of chronic ankle changes includes chronic ligamentous, tendinous and soft tissue changes. With the use MRI, specific syndromes can be defined which particularly affect the ankle joint in a chronic way, such as the os trigonum syndrome, the anterolateral impingement syndrome and the sinus tarsi syndrome. Nevertheless, plain film radiographs are still the basic element of any investigation. MRI, however, can be potentially used as a second investigation, saving an unnecessary cascade of investigations with ultrasound and CT. The latter investigations are used only with very specific indications, for instance CT for subtle bone structures and sonography for a limited investigation of tendons or evaluation of fluid. Particularly due to the possibilities of MRI and the development of special gradient-echo imaging or

  10. Total ankle arthroplasty with severe preoperative varus deformity.

    Hanselman, Andrew E; Powell, Brian D; Santrock, Robert D

    2015-04-01

    Advancements in total ankle arthroplasty (TAA) over the past several decades have led to improved patient outcomes and implant survivorship. Despite these innovations, many implant manufacturers still consider a preoperative coronal plane deformity greater than 10° a relative contraindication to TAA. Without proper intraoperative alignment, these implants may experience abnormal wear and hardware failure. Correcting these deformities, often through the use of soft tissue procedures and/or osteotomies, not only increases the difficulty of a case, but also the intraoperative time and radiation exposure. The authors report a case in which a 54-year-old man with a severe right ankle varus deformity of 29° underwent successful TAA using the INBONE II Prophecy total ankle system (Wright Medical Technology, Inc, Memphis, Tennessee) and additional soft tissue reconstruction. Intraoperatively, the patient's coronal deformity was corrected to 1.8°. At 8 months postoperatively, the patient ambulated without restriction and had substantial improvement in validated patient outcome scores, specifically the Academy of Orthopaedic Surgeons Foot and Ankle Module and the Short Form Health Survey-12 This unique report documents the first time that this particular implant, with an exclusive preoperative computed tomography-derived patient-specific guide, has been used effectively for a severe preoperative varus deformity greater than 20° without the need for an osteotomy. Future studies should be directed toward the prospective evaluation of different total ankle implant systems and their outcomes with severe coronal plane deformity, specifically computed tomography-derived patient-specific guided implants.

    Objective. To describe the MR imaging appearance of radiation-induced brachial plexopathy. Design. MR imaging was performed in two patients with the clinical diagnosis of radiation-induced brachial plexopathy and in one with surgically proven radiation fibrosis of the brachial plexus. Patients. Three patients who had had radiation therapy to the axilla and supraclavicular region (two with breast carcinoma and one with Hodgkin`s lymphoma) presented with symptoms in the arm and hand. To exclude metastases or tumor recurrence MR imaging was performed. Results and conclusion. In one patient, fibrosis showing low signal intensity was found, while in two patients high signal intensity fibrosis surrounding the brachial plexus was found on the T2-weighted images. In one case gadolinium enhancement of the fibrosis was seen 21 years after radiation therapy. It is concluded that radiation-induced brachial plexopathy can have different MR imaging appearances. We found that radiation fibrosis can have both low or high signal intensities on T2-weighted images, and that fibrosis can enhance even 21 years after radiation therapy. (orig.). With 3 figs.

  12. Role of dexamethasone in brachial plexus block

    To evaluate the effect of dexamethasone added to (lignocaine) on the onset and duration of axillary brachial plexus block. Study Design: Randomized controlled trial. Place and Duration of Study: Combined Military Hospital Rawalpindi, from September 2009 to March 2010. Patients and Methods: A total of 100 patients, who were scheduled for elective hand and forearm surgery under axillary brachial plexus block, were randomly allocated to group A in which patients received 40 ml 1.5% lidocaine with 2 ml of isotonic saline (0.9%) and group B in which patients received 40 ml 1.5% lidocaine with 2 ml of dexamethasone (8 mg). Nerve stimulator with insulated needle for multiple stimulations technique was used to locate the brachial plexus nerves. After the injection onset of action and duration of sensory blockade of brachial plexus were recorded at 5 minutes and 15 minutes interval. Results: Group A showed the onset of action of 21.64 ± 2.30 min and in group B it was 15.42 ± 1.44 min (p< 0.001). Duration of nerve block was 115.08 ± 10.92 min in group A and 265.42 ± 16.56 min in group B (p < 0.001). Conclusion: The addition of dexamethasone to 1.5% lignocaine solution in axillary brachial plexus block prolongs the duration of sensory blockade significantly. (author)

  13. Ultrasonography of ankle ligaments

    The lateral collateral ligament of the ankle is a complex of 3 ligaments: The anterior and posterior talofibular ligaments and the calcaneofibular ligament; these ligaments work together to support the lateral aspect of the ankle. The anterior talofibular (ATF) ligament (Fig. 1) runs from the anterior of the talus. The probe is placed in a slightly oblique position from the malleolus toward the forefoot. The ligament is hyperechoic when its fibres are perpendicular to the ultrasound beam (anisotropy artifact is present in ligaments as well as in tendons). It is approximately 2 mm thick and, during examination, must be straight and tight from one insertion point to the other, as seen in Fig. 2. The posterior talofibular (PTF) ligament, which runs from the posterior part of the malleolus to the posterior part of the talus, is difficult to see on US, being partially or sometimes completely hidden by the malleolus. The calcaneofibular ligament forms the middle portion of the lateral collateral ligament. It is tight between the inferior part of the lateral malleolus and the calcaneus, and runs in a slightly posterior oblique direction toward the heel (Fig. 3). The ligament lies on the deep surface of the fibular tendons, forming a hammock to fall deep on the calcaneus surface (Fig. 4). The calcaneofibular ligament is approximately 2-3 nun thick and is hyperechoic in the distal two-thirds only because of the obliquity of the proximal part. When examining this ligament, it is mandatory that the ankle be flexed dorsally; this stretches the ligament so that it can be seen clearly. (author)

    Full Text Available Objectives: To document the prevalence and spectrum of musculoskeletal ultrasound (MSKUS findings at different parts of the foot. Materials and Methods: All MSKUS studies conducted on the foot during a 2-year period (2012-2013 at the Department of Radiology were reviewed. Demographic parameters including age, gender, and MSKUS findings were documented. Results: Three hundred and sixty-four studies had been conducted in the 2-year period. Ninety-three MSKUS evaluations were done for the ankle, 30 studies for the heel, and 241 for the rest of the foot. The most common MSKUS finding at the ankle was tenosynovitis, mostly in female patients; at the heel it was Achilles tendonitis, also mostly in female patients; and for the rest of the foot it was fluid collection and presence of foreign body, mainly in male patients. The number of different MSKUS abnormalities that were reported was 9 at the ankle, 9 at the heel, and 21 on the rest of the foot. Conclusions: MSKUS has the potential for revealing a huge spectrum of abnormalities. The most common finding was collection/hematoma and foreign bodies at the foot, tenosynovitis at the ankle, and Achilles tendinitis at the heel.

    Purpose To assess brachial plexus magnetic resonance (MR) imaging features and limb-girdle muscle abnormalities as signs of muscle denervation in patients with amyotrophic lateral sclerosis (ALS). Materials and Methods This study was approved by the local ethical committees on human studies, and written informed consent was obtained from all subjects before enrollment. By using an optimized protocol of brachial plexus MR imaging, brachial plexus and limb-girdle muscle abnormalities were evaluated in 23 patients with ALS and clinical and neurophysiologically active involvement of the upper limbs and were compared with MR images in 12 age-matched healthy individuals. Nerve root and limb-girdle muscle abnormalities were visually evaluated by two experienced observers. A region of interest-based analysis was performed to measure nerve root volume and T2 signal intensity. Measures obtained at visual inspection were analyzed by using the Wald χ(2) test. Mean T2 signal intensity and volume values of the regions of interest were compared between groups by using a hierarchical linear model, accounting for the repeated measurement design. Results The level of interrater agreement was very strong (κ = 0.77-1). T2 hyperintensity and volume alterations of C5, C6, and C7 nerve roots were observed in patients with ALS (P brachial nerve roots do not exclude a diagnosis of ALS and suggest involvement of the peripheral nervous system in the ALS pathogenetic cascade. MR imaging of the peripheral nervous system and the limb-girdle muscle may be useful for monitoring the evolution of ALS and distinguishing patients with ALS from those with inflammatory neuropathy, respectively.

  16. Association of posterior tibial tendon abnormalities with abnormal signal intensity in the sinus tarsi on MR imaging

    Objective. To evaluate the association of abnormal signal intensity within the sinus tarsi with abnormalities of the posterior tibial tendon (PTT) on MR imaging. Design and patients. Sinus tarsi abnormalities were identified on 30 ankle MR examinations in 29 patients. The PTT and anterior talofibular ligament were retrospectively analyzed for abnormalities in these same patients. Results and conclusions. Tears of the anterior talofibular ligament were found in 13 of 30 (43%) ankles. PTT abnormalities (complete tear, partial tear or dislocation) were seen in 14 of 30 (47%) studies, and were distributed relatively equally between those patients with and without lateral ligament tears. Our results provide evidence of an association between abnormalities of the PTT and the sinus tarsi. The finding of abnormal signal intensity within the sinus tarsi on MR imaging should alert the radiologist to potential abnormalities of the PTT. (orig.)

    Superficial peroneal neuropathy is a known complication of foot and ankle arthroscopy. A 27-year-old man developed pain and paresthesia on the medial side of the dorsum of his left foot after ankle arthroscopy. An electrodiagnostic study revealed conduction abnormality in the medial branch of superficial peroneal nerve, in which neuroma-in-continuity was subsequently detected by ultrasonography. After neuroma excision and nerve graft, the subject's neuropathic pain was substantially improved. PMID:24486918

  20. Herpetic Brachial Plexopathy: Application of Brachial Plexus Magnetic Resonance Imaging and Ultrasound-Guided Corticosteroid Injection.

    Kim, Jeong-Gil; Chung, Sun G

    2016-05-01

    Herpes zoster, commonly known as shingles, is an infectious viral disease characterized by painful, unilateral skin blisters occurring in specific sensory dermatomes. Motor paresis is reported in 0.5% to 5% of patients. Although the mechanism of zoster paresis is still unclear, the virus can spread from the dorsal root ganglia to the anterior horn cell or anterior spinal nerve roots. It rarely involves the brachial plexus. We report a case of brachial plexitis following herpes zoster infection in which pathological lesions were diagnosed using brachial plexus magnetic resonance imaging and treated with ultrasound-guided perineural corticosteroid injection. PMID:26829085

  1. Radiation-induced brachial plexus paralysis

    Fifteen patients with radiation-induced brachial plexus paralysis were studied. Thirteen women had been treated for breast cancer. Two men developed symptoms and signs following radiation therapy for lung cancer. The brachial plexus paralysis initially was not static and progressed, but spontaneous arrest with permanent residual paralysis was seen in three patients. Three were noted to have intractable pain, but the major complaint of the remaining 12 was the inability to use their hands. The ten patients on whom an earlier operation directed at the brachial plexus had been performed were not relieved. Two of these were later considered excellent candidates for a tendon transfer in the hand. One did not desire surgery. The other underwent operation and showed marked improvement of her grasp and general hand function

  3. MRI of ankle sprain

    We reviewed MR (magnetic resonance) studies in 54 patients with a sprained ankle. MR examination was able to depict the following injuries: lateral collateral ligamentous injuries, fluid collection in the peroneal tendon sheath, injury to the peroneal tendon, deltoid ligamentous injuries, the extent of subcutaneous soft tissue swelling, and various kinds of osseous injuries. A total of 21 patients underwent repair or reconstructive surgery to the lateral collateral ligaments, the findings of which were correlated with those on MR examination. MR diagnosis of anterior talofibular ligamentous injury was confirmed in 16/21; the discrepancy could be attributed to remodeling and/or reorganization which progressed during the time lapse between the MR examination and surgery in three, while the misdiagnosis resulted from the difficulty in distinguishing the acute tear from the injured scar in two. The calcaneofibular ligamentous injury was confirmed in 10/12; two false negatives were responsible for the difficulty in delineating its entire length on a single image and/or in differentiating between the attenuated star and the normal calcaneofibular ligament. MR imaging is a useful tool to use in deciding the surgical indication and predicting the prognosis of the patients with ankle sprain. (author)

  5. Radiation-included brachial plexus injury

    All 449 breast cancer patients treated with post-operative radiotherapy to the breast and lymph nodes between 1982 and 1984 have been followed for 3-5.5 years. In this group two different fractionation schedules were used, one five times a fortnight and one daily, both over 6 weeks. The calculated dose to the brachial plexus was 45 Gy in 15 fractions or 5e Gy in 30 fractions. These schedules are equivalent doses using the standard NSD formula. The diagnosis of a brachial plexus injury was made clinically and computed tomography from recurrent disease. The actuarial incidence of a radiation-induced brachial plexus injury for the whole group was 4.9% at 5.5 years. No cases were seen in the first 10 months following radiotherapy. The incidence rises between 1 and 4 years and then starts to plateau. When the large fraction size group is compared with the small fraction size group the incidence at 5.5 years is 5.9% and 1.0%, respectively (p 0.09). Two different treatment techniques were used in this group but were not found to contribute to the probability of developing a brachial plexud injury. It is suggested that radiation using large doses per fraction are less well tolerated by the brachial plexus than small doses per fraction; a commonly used fractionation schedule such as 45 Gy in 15 fractions may give unacceptably high brachial plexus morbidity; and the of small doses per fraction or avoiding lymphatic irradiation is advocated.

    2012-12-01

    The brachial plexus is an important nervous system structure. It can be injured during the perinatal period and by postnatal damage. The goal of this study was to assess human fetal brachial plexus variability. A total of 220 brachial plexuses were surgically prepared from 110 human fetuses aged 14-32 weeks of fetal life (50 females and 60 males) ranging in CRL from 80 to 233 mm. The study incorporated the following methods: dissectional and anthropological, digital image acquisition, digital image processing using Image J and GIMP software, and statistical methods (Statistica 9.0). Symmetry and sexual dimorphism were examined. Anomalies of the brachial plexuses were observed in 117 (53.18 %) cases. No sexual dimorphism was found. It was observed that cord variations occurred more often on the left side. Division variants (33.64 %) occurred most often, but also cords (18.18 %) as well as root nerves and terminal ramifications (15.90 %) were found. Trunk anomalies were rare and occurred in only 5.45 % of plexuses. Three height types of median nerve roots in combination with the nerve were distinguished. In one-third of cases, median nerve root connections were found below the axillary fossa and even half in the proximal part of the humerus. In conclusion, the brachial plexus was characterized for anatomical structural variability. Most often division and cord variations were observed. Anomalies occurred regardless of sex or body side except for cord variants. Brachial plexus variation recognition is significant from the neurosurgical and traumatological point of view.

  8. Magnetic resonance neurography of the brachial plexus

    Vaishali Upadhyaya

    2015-01-01

    Full Text Available Magnetic Resonance Imaging (MRI is being increasingly recognised all over the world as the imaging modality of choice for brachial plexus and peripheral nerve lesions. Recent refinements in MRI protocols have helped in imaging nerve tissue with greater clarity thereby helping in the identification, localisation and classification of nerve lesions with greater confidence than was possible till now. This article on Magnetic Resonance Neurography (MRN is based on the authors′ experience of imaging the brachial plexus and peripheral nerves using these protocols over the last several years.

  9. Nerve Transfers for Adult Traumatic Brachial Plexus Palsy (Brachial Plexus Nerve Transfer)

    Rohde, Rachel S.; Wolfe, Scott W.

    2006-01-01

    Adult traumatic brachial plexus injuries can have devastating effects on upper extremity function. Although neurolysis, nerve repair, and nerve grafting have been used to treat injuries to the plexus, nerve transfer makes use of an undamaged nerve to supply motor input over a relatively short distance to reinnervate a denervated muscle. A review of several recent innovations in nerve transfer surgery for brachial plexus injuries is illustrated with surgical cases performed at this institution.

  10. Magnetic resonance imaging of the shoulder in children with brachial plexus birth palsy

    Five patients suffering from Erb-Duchenne brachial plexus birth palsy were prospectively studied with MRI. A group of 11 healthy children was used as a control to understand the MRI anatomy of the normal growing glenohumeral joint. A hypoplastic and flattened posterior part of the glenoid fossa and a blunt posterior labrum were found in all patients. Four patients had a blunt anterior labrum and a flattened humeral head. Three patients presented with a posterior subluxation of the humeral head. These results suggest that MRI provides a non-ionising and non-invasive method of demonstrating the early abnormalities of the shoulder associated with obstetrical brachial plexus paralysis, which may prompt orthopaedic correction.

    Brachial plexus injury represents the most severe nerve injury of the extremities. While obstetric brachial plexus injury has showed a reduction in the number of cases due to the improvements in obstetric care, brachial plexus injury in the adult is an increasingly common clinical problem. The therapeutic measures depend on the pathologic condition and the location of the injury: Preganglionic avulsions are usually not amenable to surgical repair; function of some denervated muscles can be restored with nerve transfers from intercostals or accessory nerves and contralateral C7 transfer. Postganglionic avulsions are repaired with excision of the damaged segment and nerve autograft between nerve ends or followed up conservatively. Magnetic resonance imaging is the modality of choice for depicting the anatomy and pathology of the brachial plexus: It demonstrates the location of the nerve damage (crucial for optimal treatment planning), depicts the nerve continuity (with or without neuroma formation), or may show a completely disrupted/avulsed nerve, thereby aiding in nerve-injury grading for preoperative planning. Computed tomography myelography has the advantage of a higher spatial resolution in demonstration of nerve roots compared with MR myelography; however, it is invasive and shows some difficulties in the depiction of some pseudomeningoceles with little or no communication with the dural sac.

  15. Arthrography of the ankle sprains

    Ankle arthrography, by direct puncture of joint cavity, is considered to be a simple and accurate diagnostic method for a precise evaluation of ligamentous injury. Forty-seven cases of ankle arthrography were successively performed in the patients of acute ankle sprains. The purpose of this study is to demonstrate how ankle arthrography can delineate the pathologic anatomy in such cases. The results are as follows: 1. Thirty cases among forty seven revealed the findings of ligament tears. 2. For better diagnostic accuracy, the arthrography should be performed within 72 hrs. after injury. 3. The anterior talofibular ligament tears were the most common (twenty-nine cases) of all and seventeen of them revealed tears without association of any other ligament tears. 4. There were ten cases of calcaneofibular ligament tears and nine of them were associated with anterior talofibular ligament tears. 5. Three cases of anterior tibiofibular and one deltoid ligament tears were demonstrated

  18. Upright MRI of glenohumeral dysplasia following obstetric brachial plexus injury.

    Nath, Rahul K; Paizi, Melia; Melcher, Sonya E; Farina, Kim L

    2007-11-01

    The purpose of this study was to evaluate the role of upright magnetic resonance imaging (MRI) shoulder scanning in the diagnosis of glenohumeral deformity following obstetric brachial plexus injury (OBPI). Eighty-nine children (ages 0.4 to 17.9 years) with OBPI who have medial rotation contracture and reduced passive and active lateral rotation of the shoulder were evaluated via upright MRI of the affected glenohumeral joint. Qualitative impressions of glenoid form were recorded, and quantitative measurements were made of glenoid version and posterior subluxation. Glenoid version of the affected shoulder averaged -16.8 +/- 11.0 degrees (range, -55 degrees to 1 degrees ), and percentage of the humeral head anterior to the glenoid fossa (PHHA) averaged 32.6 +/- 16.5% (range, -17.8% to 52.4%). The glenoid form was normal in 43 children, convex in 19 children and biconcave in 27 children. Standard MRI protocols were used to obtain bilateral images from 14 of these patients. Among the patients with bilateral MR images, glenoid version and PHHA were significantly different between the involved and uninvolved shoulders (P<.000). Glenoid version in the involved shoulder averaged -19.0 +/- 13.1 degrees (range, -52 degrees to -3 degrees ), and PHHA averaged 29.7 +/- 18.4% (range, -16.2% to 48.7%). In the uninvolved shoulder, the average glenoid version and PHHA were -5.2 +/- 3.7 degrees (range, -12 degrees to -1 degrees ) and 47.7 +/- 3.0% (range, 43% to 54%), respectively. The relative beneficial aspects of upright MRI include lack of need for sedation, low claustrophobic potential and, most important, natural, gravity-influenced position, enabling the surgeon to visualize the true preoperative picture of the shoulder. It is an effective tool for demonstrating glenohumeral abnormalities resulting from brachial plexus injury worthy of surgical exploration. PMID:17448618

  19. Tibiofemoral angle and its relation to ankle sprain occurrence.

    The lack of a normal joint orientation generates translational or shear forces across the joint. These forces can put abnormally high strain on the cartilage and the surrounding capsuloligamentous tissues. Ankle joint structure can affect or be affected by bony malformations of the surrounding areas, including the knee and hip. The aim of the current study is to examine the possible relationship between the tibiofemoral (TFA) angle and other factors (anthropometric characteristics, medical history, and age) on the occurrence of ankle sprains because its value provides useful information for the anatomical alignment of the lower extremity. The study sample consisted of 45 high-level athletes, evenly distributed among 3 sports (basketball, soccer, and volleyball). TFA measurements were made on radiographs. The study lasted 2 years. A logistic regression was used to determine the importance of each factor on the probability in question. A significance level of P = .1 was used. The factors contributing more to an ankle sprain were a previous injury of the same type followed by body mass index (BMI) and age. On the contrary, TFA was proven to be statistically nonsignificant. When the BMI variable was substituted with body inertia propensity, a derived variable, the TFA remained statistically nonsignificant. TFA magnitude does not seem to be a determinant factor that could increase the probability of spraining an ankle. PMID:20400424

  20. Dynamic high-resolution US of ankle and midfoot ligaments: normal anatomic structure and imaging technique.

    Sconfienza, Luca Maria; Orlandi, Davide; Lacelli, Francesca; Serafini, Giovanni; Silvestri, Enzo

    2015-01-01

    The ankle is the most frequently injured major joint in the body, and ankle sprains are frequently encountered in individuals playing football, basketball, and other team sports, in addition to occurring in the general population. Imaging plays a crucial role in the evaluation of ankle ligaments. Magnetic resonance imaging has been proven to provide excellent evaluation of ligaments around the ankle, with the ability to show associated intraarticular abnormalities, joint effusion, and bone marrow edema. Ultrasonography (US) performed with high-resolution broadband linear-array probes has become increasingly important in the assessment of ligaments around the ankle because it is low cost, fast, readily available, and free of ionizing radiation. US can provide a detailed depiction of normal anatomic structures and is effective for evaluating ligament integrity. In addition, US allows the performance of dynamic maneuvers, which may contribute to increased visibility of normal ligaments and improved detection of tears. In this article, the authors describe the US techniques for evaluation of the ankle and midfoot ligaments and include a brief review of the literature related to their basic anatomic structures and US of these structures. Short video clips showing dynamic maneuvers and dynamic real-time US of ankle and midfoot structures and their principal pathologic patterns are included as supplemental material. Use of a standardized imaging technique may help reduce the intrinsic operator dependence of US. Online supplemental material is available for this article. PMID:25590396

    1992-11-01

    This article presents a radiologic review of the spectrum of acquired and congenital orthopedic abnormalities found in patients with myelomeningocele. These abnormalities are caused predominantly by muscle imbalance, paralysis, and decreased sensation in the lower extremity. Iatrogenic injury, such as a postoperative tethered cord, may also cause bone abnormalities. Selected images were obtained from more than 800 children. Important entities presented include spinal curvatures such as kyphosis, scoliosis, and lordosis; subluxation and dislocation of the hip, coxa valga, contractures of the hip, and femoral torsion; knee deformities; rotational abnormalities of the lower extremity and external and internal torsion; ankle and foot abnormalities such as ankle valgus, calcaneus foot, congenital vertical talus (rocker-bottom deformity), and talipes equinovarus; and metaphyseal, diaphyseal, and physeal fractures. Familiarity with congenital abnormalities and an understanding of the pathogenesis of acquired disorders in patients with myelomeningocele are essential for proper radiologic interpretation and timely therapy.

    Highlights: • MR neurography is the imaging modality of choice in patients who have sustained brachial plexus injury. It is helpful in determining the level and extent of injury. • The authors have used a Visual Per-operative Scoring system to assess the usefulness of MR neurography in delineating the level and type of the lesion. • The imaging findings were classified based on the level of injury—root, trunk or cord. These findings were correlated with those seen on surgical exploration. A good correlation was found in the majority (65%) of patients and average correlation (30%) in others. - Abstract: Objectives: Imaging of the brachial plexus has come a long way and has progressed from plain radiography to CT and CT myelography to MRI. Evolution of MR imaging sequences has enabled good visualization of the small components of the plexus. The purpose of our study was to correlate the results of MR neurography (MRN) in patients with traumatic brachial plexopathy with their operative findings. We wanted to determine the usefulness of MRN and how it influenced surgical planning and outcome. Methods: Twenty patients with features of traumatic brachial plexopathy who were referred to the MRI section of the Department of Radiology between September 2012 and January 2014 and subsequently underwent exploration were included in the study. MR neurography and operative findings were recorded at three levels of the brachial plexus—roots, trunks and cords. Results: Findings at the level of roots and trunks were noted in 14 patients each and at the level of the cords in 16 patients. 10 patients had involvement at all levels. Axillary nerve involvement as a solitary finding was noted in two patients. These patients were subsequently operated and their studies were assigned a score based on the feedback from the operating surgeons. The MRN study was scored as three (good), two (average) or one (poor) depending on whether the MR findings correlated with operative

  4. Evaluation of the brachial plexus with MR imaging

    MR imaging allows excellent visualization of the brachial plexus, including its cervical, subscapular, and axillary course. The anatomy of the normal brachial plexus as it appears on 5-mm coronal (short TR) and axial (1st and 2nd spin-echo sequences) images obtained using a body coil at 1.5 T is presented. Normal findings are compared with examples of pathologic masses arising in or adjacent to each part of the brachial plexus. Selected surface coil views were useful in the evaluation of the proximal brachial plexus. The MR imaging demonstration of the morphology of mass lesions and their relationship to the brachial plexus is superior to CT demonstration and can be accomplished in little time and without the use of intravenous contrast media. Currently it is not possible to achieve sufficient detail to detect infiltrative, fibrotic, or atrophic processes unless these cause significant changes in the size, shape, or position of the brachial plexus

    The chronic ankle pain is a very frequent clinical problem, which is often characterized by a painful mechanical limitation of full-range ankle movement. A large amount of causes are involved in its pathogenesis, but the most common forms are secondary to an osseous or soft tissue abnormality. Especially for professional athletes, impingement lesions are the most important causes of chronic pain; however, this symptomatology can also affect ordinary people, mostly in those who work in environments that cause severe mechanical stress on the joints. This group of pathologies is characterized by a joint conflict secondary to an abnormal contact among bone surfaces or between bones and soft tissues. Diagnosis is mainly clinic and secondly supported by imaging in order to localize the critical area of impingement and determine the organic cause responsible for the joint conflict. Treatments for different forms of impingement are similar. Usually, the first step is a conservative approach (rest, physiotherapy, ankle bracing, shoe modification and local injection of corticosteroids), and only in case of unsuccessful response, the second step is the operative treatment with open and arthroscopic techniques. The aim of the study is to describe different MR imaging patterns, comparing our data with those reported in the literature, in order to identify the best accurate diagnostic protocol. PMID:23949936

  10. Imaging tumours of the brachial plexus

    Tumours of the brachial plexus are rare lesions and may be classified as benign or malignant. Within each of these groups, they are further subdivided into those that are neurogenic in origin (schwannoma, neurofibroma and malignant peripheral nerve sheath tumour) and those that are non-neurogenic. Careful pre-operative diagnosis and staging is essential to the successful management of these lesions. Benign neurogenic tumours are well characterized with pre-operative MRI, appearing as well-defined, oval soft-tissue masses, which are typically isointense on T1-weighted images and show the ''target sign'' on T2-weighted images. Differentiation between schwannoma and neurofibroma can often be made by assessing the relationship of the lesion to the nerve of origin. Many benign non-neurogenic tumours, such as lipoma and fibromatosis, are also well characterized by MRI. This article reviews the imaging features of brachial plexus tumours, with particular emphasis on the value of MRI in differential diagnosis. (orig.)

  11. Myelography in obstetric palsies of brachial plexus

    The use of myelography in obstetric palsies of brachial plexus is aimed at diagnosing root avulsion.This kind of lesion appears as the disappearance of the slightly-transparent nerve roots which might be combined either with pseudo-meningocele or with deformation of radicular pouch. This study 69 operated patients who had previously undergone myelography have been considered. In 74.2% of cases mylographic findings were confirmed at surgery.False positives and false negatives were 9.7% and 3.2%, respectively. Uncorrect diagnoses were made in 12.9% of cases, because of misread lesions and uncorrect evaluation of their location, usually at the cervicol-dorsal junction.No side-effects were observed. Myelography appears thus to be extremely useful for both the preoperative evaluation and the choice of surgery in newborn children with obstetric palsy of the brachial plexus

    Myelography has been the most popular and reliable method for evaluation of nerve root avulsion in brachial plexus injury. However, it is invasive because it requires the use of contrast medium, dural puncture and exposure to radiation. In addition, it has a fault. When a nerve rootlet is not filled with contrast medium, it is impossible to evaluate it. It has sometimes been a problem in the injury to upper roots. Recently, MRI also has been used for diagnosis of brachial plexus injury. But it was not until recently that it has had a high resolution to detect affected nerve rootlets. We have used MR myelography with high resolution for diagnosis of brachial plexus injury. The purpose of this study is to investigate the usefulness of it. MR myelography was preoperatively performed in 14 cases, consisting of 13 traumatic brachial plexus injuries and an obstetrical palsy. In them, 12 cases had root avulsion injuries and 2 cases had infraclavicular injuries. A 1.5 Tesla MR system (Philips) and a cervical coil were used. Coronal sections with 2 mm-overcontiguous thickness were obtained by heavily T2-weighted sequence fast spin echo (TR/TE=3000/450). The fat signal was suppressed by a presaturation inversion-pulse. The scanning time was about five minutes. The three-dimensional image was reconstructed by using maximum intensity projection (MIP) method. MIP images and individual coronal images were used for evaluation for root avulsion. In evaluation the shape of a nerve sleeve and nerve rootlets was compared on both sides. The abnormal shape of a nerve sleeve or the defect of nerve rootlets was diagnosed as root avulsion. The brachial plexus lesions were exposed operatively and examined with electrophysiologic methods (SEP and/or ESCP) in all cases. Operative findings were compared with MR myelography. Twenty-four roots had been diagnosed as normal and 46 roots had been diagnosed as root avulsion with MR myelography preoperatively. In the former only one root was

    The differential intensity of cosmic radiation shows a sequence of depressions referred to as "knees" in a large energy band above 10^15 eV. The global depression entailed in the complete spectrum with respect to the extrapolated intensity based on low energy data amounts to a maximum factor of 8, occurring at 5 x 10^18 eV, where flux measurements exhibit a relative minimum, referred to as the "ankle". It is demonstrated by a full simulation of cosmic ray trajectories in the Galaxy that the intensity minimum around the ankle energy is primarily due to the nuclear interactions of the cosmic ions with the interstellar matter and to the galactic magnetic field. "Ankles" signal the onset energies of the rectilinear propagation in the Milky Way at the Earth, being for example, 4 x 10^18 eV for helium and 6 x 10^19 eV for iron. The ankle, in spite of its notable importance at the Earth, is a local perturbation of the universal spectrum which, between the knee and the ankle, decreases by a round factor 10^9, regaini...

  15. Posterior Ankle Structure Injury During Total Ankle Replacement.

    Reb, Christopher W; McAlister, Jeffrey E; Hyer, Christopher F; Berlet, Gregory C

    2016-01-01

    Total ankle replacement studies have focused on reporting complications that are directly observed clinically or radiographically, including wound problems, technical errors, implant loosening, subsidence, infection, bone fractures, and heterotopic ossification. However, patients can still experience unresolved pain even when these problems have been ruled out. We initiated a study to more clearly define the relative risk of injury to the anatomic structures in the posterior ankle during total ankle replacement using a third-generation implant system. Ten fresh-frozen adult cadaveric below-the-knee specimens were positioned in the intraoperative positioning frame of an approved total ankle replacement system and adjusted to achieve proper foot alignment using fluoroscopic imaging. The relationship between the tibial cutting guide pins and the posterior neurovascular and tendon structures was measured using digital calipers. High rates of posterior structural injury were found. Nearly all proximal-medial pins encountered a posteromedial neurovascular structure, most commonly the tibial nerve. The distal-medial pins mainly encountered posteromedial tendinous structures, in particular, the flexor digitorum longus tendon. The proximal lateral pins were highly likely to encounter the Achilles tendon and the sural nerve. Our results support our hypothesis that the tibial neurovascular structures are at the greatest risk when preparing for and completing the bony resection, particularly with the medial and proximal cuts. Posterior ankle soft tissue structure injuries can occur during implantation but currently with unknown frequency and undetermined significance. Further study of posterior structural injuries could result in a more informed approach to post-total ankle replacement complications and management. PMID:27291681

  18. Evaluation of brachial plexus injury by MRI

    Objective: To evaluate the diagnostic value of MRI in brachial plexus injury. Methods: Total 98 patients with brachial plexus injury were examined by MRI before operation. Fifty-four of 98 patients MR imaging were obtained by 0.5 Tesla scanner and other 44 patients were obtained by 1.5 Tesla scanner. The scanning sequences include: SE T1WI, T2WI, FFE T2WI and T2WI SPIR. Exploration of the supraclavicular plexus was carried out and the MR imaging were compared with the operative finding in 63 patients. Thirty-five patients who had not surgery, were followed-up. Results: MR imaging found pre-ganglionic injuries in 45 patients and post- ganglionic injuries in 56 patients. Pre- and post- ganglionic injuries simultaneously in 16 patients among them. MR imaging can not find injury, sings in 13 patients. The positive rate was 86.73%. MR imaging finding of pre-ganglionic injuries include: (1) Spinal cord edema and hemorrhage, 2 patients (4.44%). (2) Displacement of spinal cord, 17 patients (37.78%). (3) Traumatic meningoceles, 37 patients( 82.22% ). (4) Absence of roots in spinal canal, 25 patients (55.56%). (5) Scarring in the spinal cnanl,24 patients (53.33%). (6) Denervation of erector spine, 13 patients (28.89%). MR imaging finding of post-ganglionic injuries include: (1) Trunk thickening with hypointensities in T2WI, 23 patients (41.07%). (2) Nerve trunk complete loss of continuity with disappeared of nerve structure, 16 patients (28.57%). (3) Continuity of nerve trunk was well with disappearance of nerve structure, 14 patients (25.00%). (4) Traumatic neurofibroma, 3 patients (5.36%). Conclusion: MR imaging can reveal Pre- and post- ganglionic injuries of brachial plexus simultaneously. MR imaging is able to determine the location (pre- or post- ganglionic) and extent of brachial plexus injury, provided important information for treatment method selection. (authors)

    Injuries of the ankle joint have a high incidence in daily life and sports, thus, playing an important socioeconomic role. Therefore, proper diagnosis and adequate treatment are mandatory. While most of the ligament injuries around the ankle joint are treated conservatively, great controversy exists on how to treat deltoid ligament injuries in ankle fractures. Missed injuries and inadequate treatment of the medial ankle lead to inferior outcome with instability, progressive deformity, and ank...

  7. Ankle impingement syndromes; Impingement-Syndrome am Sprunggelenk

    Eiber, Matthias; Woertler, Klaus [Klinikum rechts der Isar, Muenchen (Germany). Inst. fuer Roentgendiagnostik

    2010-06-15

    Soft-tissue and osseous impingement syndromes can be an important cause of chronic ankle pain, particularly in the professional athlete. The classification of ankle impingement syndromes is based to their anatomical location around the tibiotalar joint. The most important impingement syndromes are anterolateral, anterior and posterior impingement with more recent studies describing posteromedial and anteromedial impingement. Usually conventional radiography is the first imaging technique to be performed as it allows assessment of potential bone abnormalities, particularly in anterior and posterior joint compartments. Computed tomography (CT) only plays a role in the assessment of the posterior impingement. Magnetic resonance (MR) imaging is regarded as the modality of choice as it is able to demonstrate both osseous and soft tissue changes, such as bone marrow edema, capsular and ligametous thickening, and localized synovitis.

  11. Expecting ankle tilts and wearing an ankle brace influence joint control in an imitated ankle sprain mechanism during walking.

    Gehring, Dominic; Wissler, Sabrina; Lohrer, Heinz; Nauck, Tanja; Gollhofer, Albert

    2014-03-01

    A thorough understanding of the functional aspects of ankle joint control is essential to developing effective injury prevention. It is of special interest to understand how neuromuscular control mechanisms and mechanical constraints stabilize the ankle joint. Therefore, the aim of the present study was to determine how expecting ankle tilts and the application of an ankle brace influence ankle joint control when imitating the ankle sprain mechanism during walking. Ankle kinematics and muscle activity were assessed in 17 healthy men. During gait rapid perturbations were applied using a trapdoor (tilting with 24° inversion and 15° plantarflexion). The subjects either knew that a perturbation would definitely occur (expected tilts) or there was only the possibility that a perturbation would occur (potential tilts). Both conditions were conducted with and without a semi-rigid ankle brace. Expecting perturbations led to an increased ankle eversion at foot contact, which was mediated by an altered muscle preactivation pattern. Moreover, the maximal inversion angle (-7%) and velocity (-4%), as well as the reactive muscle response were significantly reduced when the perturbation was expected. While wearing an ankle brace did not influence muscle preactivation nor the ankle kinematics before ground contact, it significantly reduced the maximal ankle inversion angle (-14%) and velocity (-11%) as well as reactive neuromuscular responses. The present findings reveal that expecting ankle inversion modifies neuromuscular joint control prior to landing. Although such motor control strategies are weaker in their magnitude compared with braces, they seem to assist ankle joint stabilization in a close-to-injury situation. PMID:24365326

    Ankle sprains constitute the majority of ankle injuries, and result in pain, limited mobility/exercise and loss of school/work days. Ankle sprains involve at least one of the ankle ligaments and range from a micro tear to complete tear of the ligament or group of ligaments. The most common mechanism of ankle sprains is inversion stress of a plantar-flexed foot, while the most frequently injured ligament is the anterior talofibular ligament. The attending clinician needs to stratify the risk o...

    2015-07-01

    [Purpose] The purpose of this study was to report the effects of ankle inversion taping using kinesiology tape in a patient with a medial ankle sprain. [Subject] A 28-year-old amateur soccer player suffered a Grade 2 medial ankle sprain during a match. [Methods] Ankle inversion taping was applied to the sprained ankle every day for 2 months. [Results] His symptoms were reduced after ankle inversion taping application for 2 months. The self-reported function score, the reach distances in the Star Excursion Balance Test, and the weight-bearing ankle dorsiflexion were increased. [Conclusion] This study showed that ankle inversion taping using kinesiology tape may be an effective therapy for a patient with a medial ankle sprain. PMID:26311991

  15. Syndesmotic ankle sprains in athletes.

    Williams, Glenn N; Jones, Morgan H; Amendola, Annunziato

    2007-07-01

    Ankle sprains are among the most common athletic injuries and represent a significant source of persistent pain and disability. Despite the high incidence of ankle sprains in athletes, syndesmosis injuries have historically been underdiagnosed, and assessment in terms of severity and optimal treatment has not been determined. More recently, a heightened awareness in sports medicine has resulted in more frequent diagnoses of syndesmosis injuries. However, there is a low level of evidence and a paucity of literature on this topic compared with lateral ankle sprains. As a result, no clear guidelines are available to help the clinician assess the severity of injury, choose an imaging modality to visualize the injury, make a decision in terms of operative versus nonoperative treatment, or decide when the athlete may return to play. Increased knowledge and understanding of these injuries by clinicians and researchers are essential to improve the prevention, diagnosis, and treatment of this significant condition. This review will discuss the anatomy, mechanism of injury, diagnosis, and treatment of syndesmosis sprains of the ankle while identifying controversies in management and topics for future research.

  16. Comparison of three ankle-foot orthosis configurations for children with spastic hemiplegia.

    Buckon, C E; Thomas, S S; Jakobson-Huston, S; Sussman, M; Aiona, M

    2001-06-01

    The purpose of this study was to examine the effectiveness of the hinged ankle-foot orthosis (HAFO), posterior leaf spring (PLS), and solid ankle-foot orthosis (SAFO), in preventing contracture, improving efficiency of gait, and enhancing performance of functional motor skills in 30 children (21 male, 9 female; mean age 9 years 4 months; age range 4 to 18 years,) with spastic hemiplegia. Following a 3-month baseline period of no ankle-foot orthosis (AFO) use, each AFO was worn for 3 months after which ankle range of motion, gait analysis, energy consumption, and functional motor skills were assessed. The HAFO and PLS increased passive ankle dorsiflexion and normalization of ankle rocker function during gait. Normalization of knee motion in stance was dependent upon the knee abnormality present and AFO configuration. The HAFO was the most effective in controlling knee hyperextension in stance, while PLS was the most effective in promoting knee extension in children with >10 degree knee flexion in stance. Energy efficiency was improved in 21 of the children, with 13 of these children demonstrating the greatest improvement in HAFO and PLS. Improvements in functional mobility were greatest in the HAFO and PLS. PMID:11409825

  2. Brachial plexus palsy caused by halo traction before posterior correction in patients with severe scoliosis

    QIAN Bang-ping; QIU Yong; WANG Bin; YU Yang; ZHU Ze-zhang

    2007-01-01

    Objective: To explore the clinical features and treatment results of brachial plexus palsy caused by halo traction before posterior correction in patients with severe scoliosis.Methods: A total of 300 cases of severe scoliosis received halo traction before posterior correction in our department from July 1997 to November 2004. Among them, 7 cases were complicated with brachial plexus palsy.The average Cobb angle was 110° (range, 90°-135°).Diagnoses were made as idiopathic scoliosis in 1 case,congenital scoliosis in 3 cases, and neuromuscular scoliosis in 3 cases. Additionally, diastematomyelia and tethered cord syndrome were found in 3 cases and thoracolumbar kyphosis in 2 cases. Weight of traction was immediately reduced when the patient developed any abnormal neurological symptoms in the upper extremity, and rehabilitation training was undertaken. Simultaneously,neurotrophic pharmacotherapy was applied, and the neurological function restoration of the upper limbs and the recovery time were documented.Results: Traction was used for an average of 3.5 weeks (range, 2-6 weeks) before spinal fusion for these 7 patients. The average traction weight was 8 kg, which was 19% on average (range, 13%-26%) of the average body weight (40.2 kg). These 7 patients had long and thin body configuration with a mean height of 175 cm. The duration between symptoms of brachial plexus paralysis and the diagnosis was 1-3 hours. All of these 7 patients presented various degrees of numbness in the ulnar side of the hand and forearm. Median nerve paresis was found in 3 cases and ulnar nerve paresis in 4 cases. Complete recovery of the neurological function had been achieved by the end of three months.Conclusions: The clinical features of brachial plexus palsy caused by halo traction include median nerve paresis,ulnar nerve paralysis, and numbness in the ulnar side of the hand and forearm, which may be due to the injury of the inferior part of the brachial plexus, i.e. , damage of Cs and

  3. Motor cortex neuroplasticity following brachial plexus transfer

    Michael Biggs

    2013-08-01

    Full Text Available In the past decade, research has demonstrated that cortical plasticity, once thought only to exist in the early stages of life, does indeed continue on into adulthood. Brain plasticity is now acknowledged as a core principle of brain function and describes the ability of the central nervous system to adapt and modify its structural organization and function as an adaptive response to functional demand. In this clinical case study we describe how we used neuroimaging techniques to observe the functional topographical expansion of a patch of cortex along the sensorimotor cortex of a 27 year-old woman following brachial plexus transfer surgery to re-innervate her left arm. We found bilateral activations present in the thalamus, caudate, insula as well as across the sensorimotor cortex during an elbow flex motor task. In contrast we found less activity in the sensorimotor cortex for a finger tap motor task in addition to activations lateralised to the left inferior frontal gyrus and thalamus and bilaterally for the insula. From a pain perspective the patient who had experienced extensive phantom limb pain before surgery found these sensations were markedly reduced following transfer of the right brachial plexus to the intact left arm. Within the context of this clinical case the results suggest that functional improvements in limb mobility are associated with increased activation in the sensorimotor cortex as well as reduced phantom limb pain.

  4. Imaging tumours of the brachial plexus

    Saifuddin, Asif [Department of Radiology, The Royal National Orthopaedic Hospital NHS Trust, Brockley Hill, HA7 4LP, Stanmore (United Kingdom)

    2003-07-01

    Tumours of the brachial plexus are rare lesions and may be classified as benign or malignant. Within each of these groups, they are further subdivided into those that are neurogenic in origin (schwannoma, neurofibroma and malignant peripheral nerve sheath tumour) and those that are non-neurogenic. Careful pre-operative diagnosis and staging is essential to the successful management of these lesions. Benign neurogenic tumours are well characterized with pre-operative MRI, appearing as well-defined, oval soft-tissue masses, which are typically isointense on T1-weighted images and show the ''target sign'' on T2-weighted images. Differentiation between schwannoma and neurofibroma can often be made by assessing the relationship of the lesion to the nerve of origin. Many benign non-neurogenic tumours, such as lipoma and fibromatosis, are also well characterized by MRI. This article reviews the imaging features of brachial plexus tumours, with particular emphasis on the value of MRI in differential diagnosis. (orig.)

  5. Muscular and glenohumeral changes in the shoulder after brachial plexus birth palsy: an MRI study in a rat model

    Soldado Francisco

    2012-12-01

    Full Text Available Abstract Background Shoulder abnormalities are the major cause of morbidity in upper brachial plexus birth palsy (BPBP. We developed a rat model of upper trunk BPBP and compared our findings to previously reported animal models and to clinical findings in humans. Methods Forty-three 5-day-old newborn rats underwent selective upper trunk neurectomy of the right brachial plexus and were studied 3 to 20 weeks after surgery. The passive shoulder external rotation was measured and the shoulder joint was assessed bilaterally by a 7.2T MRI bilaterally. Results We found a marked decrease in passive shoulder external rotation, associated with a severe subscapularis muscle atrophy and contracture. None however developed the typical pattern of glenohumeral dysplasia. Conclusions In contradiction with previous reports, our study shows that the rat model is not adequate for preclinical studies of shoulder dysplasia. However, it might serve as a useful model for studies analyzing shoulder contracture occurring after upper BPBP.

  6. Median nerve's loop in the arm penetrated by a superficial brachial artery: case report and neurosurgical considerations

    George K. Paraskevas

    2015-08-01

    Full Text Available Median nerve is commonly formed by the union of the lateral and medial cord of the brachial plexus, which embrace the third part of the axillary artery. Formation of a median nerve's loop is a very rare condition. We present a cadaveric case, in which the right median nerve was found at the upper arm forming a fusiform neural loop penetrated by a superficial brachial artery, which continued over the forearm as the radial artery. The literature concerning nerve loops and traversing arteries is discussed, as well as the relevant embryology. We consider that such nerve loops constitute vulnerable sites of the nerve trunk since it is compressed by the pulsation of the abnormal traversing artery. Moreover, neurosurgeons should keep in mind that in case of existing arterial variation, variation of the associated neural structures may co-exist. [Int J Res Med Sci 2015; 3(8.000: 2123-2125

    2011-01-15

    Our purpose was to clarify the magnetic resonance (MR) imaging characteristics of the brachial and lumbar plexuses in patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) using various kinds of sequences, including diffusion-weighted images (DWI). We evaluated the MR imaging findings for lumbar and/or brachial nerve plexuses in 13 CIDP patients and 11 normal volunteers. The nerve swelling was evaluated in comparison with normal controls by coronal short tau inversion recovery (STIR), and signal abnormalities were evaluated by coronal STIR, T1-weighted images, and DWIs. The degrees of contrast enhancement and apparent diffusion coefficient (ADC) values of the plexus were also assessed. In the patient group, diffuse enlargement and abnormally high signals were detected in 16 out of 24 plexuses (66.7%) on STIR, a slightly high signal was detected in 12 of 24 plexuses (50%) on T1-weighted images, and a high-intensity signal was detected in 10 of 18 plexuses (55.6%) on DWIs with high ADC values. Contrast enhancement of the plexuses was revealed in 6 of 19 plexuses (31.6%) and was mild in all cases. There were statistically significant differences between the ADC values of patients with either swelling or abnormal signals and those of both normal volunteers and patients without neither swelling nor abnormal signals. There were no relationships between MR imaging and any clinical findings. STIR is sufficient to assist clinicians in diagnosing CIDP. T1-weighted images and DWIs seemed useful for speculating about the pathological changes in swollen plexuses in CIDP patients. (orig.)

  14. Obstetrical brachial plexus injuries: a MRI diagnostic approach

    Purpose: To demonstrate the utility of Magnetic Resonance (MR) imaging in the evaluation of the obstetric injuries of the brachial plexus. Material and methods: 23 patients with semiology of brachial plexus palsy have been evaluated with high field MR. Patients were evaluated with a brain coil in axial, oblique coronal and sagittal planes with T1, T2 and STIR sequences. Results: In four patients (17%) the study was normal. In 19 patients (83%) we got pathological findings (pseudomeningoceles, neuromas, tumour and arachnoid cyst). Conclusion: The MR is a non-invasive method that permits to determinate the site and range of the brachial plexus damage, allowing to plan therapy. (author)

    Lin, Chung-Wei Christine; Hiller, Claire E; de Bie, Rob A.

    2010-01-01

    The most common ankle injuries are ankle sprain and ankle fracture. This review discusses treatments for ankle sprain (including the management of the acute sprain and chronic instability) and ankle fracture, using evidence from recent systematic reviews and randomized controlled trials. After ankle sprain, there is evidence for the use of functional support and non-steroidal anti-inflammatory drugs. There is weak evidence suggesting that the use of manual therapy may lead to positive short-t...

  20. Electrodiagnosis in traumatic brachial plexus injury

    K A Mansukhani

    2013-01-01

    Full Text Available Electrodiagnosis (EDX is a useful test to accurately localize the site, determine the extent, identify the predominant pathophysiology, and objectively quantify the severity of brachial plexopathies. It can also be used to examine muscles not easily assessed clinically and recognize minimal defects. Post-operatively and on follow up studies, it is important for early detection of re-innervation. It can be used intra-operatively to assess conduction across a neuroma, which would help the surgeon to decide further course of action. Localization of the site of the lesion can be very challenging as there may be multiple sites of involvement and hence the electroneuromyographic evaluation must be adequate. The unaffected limb also needs to be examined for comparison. The final impression must be co-related with the type and severity of injury.

  1. Brachial access technique for aortoiliac stenting revisited

    2007-01-01

    We report a modified technique to perform iliac artery stenting through the brachial artery access. A 6F Brite tip sheath (Cordis, Jonhson & Jonhson Medical, Miami Lakes, FL, USA) is inserted into either brachial artery and a standard 4F Judkins Right diagnostic catheter was inserted over a 260 cm 0.038" Terumo Stiff wire (Terumo Corp, Tokyo, Japan) through the sheath. The catheter is navigated down to the aortic bifurcation, and after selecting the common iliac artery ostium, the wire is navigated through the lesion and advanced to the ipsilateral superficial femoral arteries. The catheter should be then moved forward over the wires beyond the lesion and the Terumo guidewire is replaced by two 0.038" 260 cm Supracor wires (Boston Scientific Corporation, San Jose, CA, USA). In order to facilitate advancement of the stent without risk of dislodgement as well as to check the position with low contrast dose injection, a 6 F (or 7F if large stent is selected) 90cm Shuttle Flexor introducer long sheath (Cook Group, Bloomington, IN, USA) should be advanced over the Supracor wire until it reaches the common iliac artery ostium. A road-map technique can be used to check the ostium position in order to properly deploy the selected stent. This technique promises to be safe and effective offering more support than guiding catheter technique; moreover it reduces the stress on the arterial vessel at the subclavian site and enables a stiff balloon or stent catheter to be advanced even through a very elongated and calcified aorta without the risk of stent dislodgement.

  2. The Split Second Effect: The Mechanism of How Equinus Can Damage the Human Foot and Ankle.

    Amis, James

    2016-01-01

    We are currently in the process of discovering that many, if not the majority, of the non-traumatic acquired adult foot and ankle problems are caused by a singular etiology: non-neuromuscular equinus or the isolated gastrocnemius contracture. There is no question that this biomechanical association exists and in time much more will be uncovered. There are three basic questions that must be answered: why would our calves tighten as we normally age, how does a tight calf, or equinus, actually cause problems remotely in the foot and ankle, and how do the forces produced by equinus cause so many seemingly unrelated pathologies in the foot and ankle? The purpose of this paper is to address the second question: how does a tight calf mechanically cause problems remotely in the foot and ankle? There has been little evidence in the literature addressing the biomechanical mechanisms by which equinus creates damaging forces upon the foot and ankle, and as a result, a precise, convincing mechanism is still lacking. Thus, the mere concept that equinus has anything to do with foot pathology is generally unknown or disregarded. The split second effect, described here, defines exactly how the silent equinus contracture creates incremental and significant damage and injury to the human foot and ankle resulting in a wide variety of pathological conditions. The split second effect is a dissenting theory based on 30 years of clinical and academic orthopedic foot and ankle experience, keen clinical observation along the way, and review of the developing literature, culminating in examination of many hours of slow motion video of normal and abnormal human gait. To my knowledge, no one has ever described the mechanism in detail this precise. PMID:27512692

  4. Can Local Anesthesia Prevent the Injury of Brachial Plexus?

    Alaattin Ozturk

    2014-01-01

    Schwannomas (neurilemmomas) are benign tumors arising from peripheral nerve sheaths. They can be seen all over the body, but approximately half of the cases occur in the head and neck region. The schwannoma arising from brachial plexus is a rare cause of neck masses. They are rarely diagnosed preoperatively. The risk of nerve damage after excision is high under general anesthesia. In this article, a case of brachial plexus schwannoma was presented and the excision with local anesthesia was sh...

    Primary tumours of the brachial plexus are rare entities. They usually present as extrathoracic masses located in the supraclavicular region. This report describes two cases of benign schwannomas arising from the brachial plexus with an intrathoracic growth. In the first case the tumour was completely intrathoracic and it was hardly removed through a standard posterolateral thoracotomy. In the second case the tumour presented as a cervicomediastinal lesion and it was resected through a one-st...

  6. Schwannoma of the brachial plexus presenting as a cystic swelling

    Somayaji, K. S. G.; Rajeshwari, A.; Gangadhara, K. S.

    2004-01-01

    Schwannomas are benign nerve sheath tumours. A small percentage of these tumours arise from the brachial plexus. Cystic degeneration and hemorrhagic necrosis can occur in these tumours in up to 40% of the cases. Detailed preoperative evaluation and careful dissection during surgery will avoid post operative neurological complications. We report a case of schwannoma of the brachial plexus presenting as a cystic neck swelling which was successfully managed by us.

    Kylma Lorena Saldanha Chagas; Lara Cochete Moura Fé; Luiza Correa Pereira; Érika Branco; Ana Rita de Lima

    2014-01-01

    The brachial plexus is formed by the ventral roots of the spinal nerves, which unite to form the nerve trunks. It is usually formed by contributions of the last three cervical nerves and the first two thoracic nerves. Due to the scarcity of information on neuroanatomy, this study aimed to determine the macroscopic morphology of the brachial plexus of the ocelot (Leopardus pardalis). In this work, we used two ocelot specimens from the area of the Paragominas Bauxite Mine, P...

    Songning; Zhang; Michael; Wortley; Julia; Freedman; Silvernail; Daniel; Carson; Maxime; R.Paquette

    2012-01-01

    <正>Purpose:The purpose of this study was to examine effects of a sport version of a semi-rigid ankle brace(ElementTM) and a soft ankle brace (ASO) on ankle biomechanics and ground reaction forces(GRFs) during a drop landing activity in subjects with chronic ankle instability(CAD compared to healthy subjects with no history of CAI. Methods:Ten healthy subjects and 10 subjects who had multiple ankle sprains participated in the study as the control and unstable subjects, respectively.The CAI subjects were age,body mass index and gender matched with the control subjects.The arch index and ankle functions of the subjects were measured in a subject screening session.During the biomechanical test session,participants performed five trials of drop landing from 0.6 m,wearing no brace(NB).Element? brace and ASO brace.Simultaneous recording of three-dimensional kinematic(240 Hz) and GRF(1200 Hz) data were performed. Results:The CAI subjects had lower ankle functional survey scores.The arch index and deformity results showed greater arch deformity of ElementTM against a static load than in NB and ASO due to greater initial arch position held by the brace.CAI participants had greater eversion velocity than healthy controls.The ASO brace reduced the first peak vertical GRF whereas ElementTM increased 2nd peak vertical GRF. ElementTMbrace reduced eversion range of motion(ROM) and peak eversion velocity compared to NB and ASO.In addition,ElementTM reduced dorsiflexion ROM and increased peak plantarflexion moment compared to NB and ASO. Conclusion:Results of static arch measurements and dynamic ankle motion suggest that the restrictions offered by both braces are in part due to more dorsiflexed ankle positions at contact,and higher initial arch position and stiffer ankle for ElementTM.

  12. Redefining prosthetic ankle mechanics: non-anthropomorphic ankle design.

    LaPrè, Andrew K; Sup, Frank

    2013-06-01

    The moment transferred at the residual limb socket interface of transtibial amputees can be a limiting factor of the comfort and activity level of lower limb amputees. The high pressures seen can be a significant source of pain, as well as result in deep tissue damage. The compensation of the sound limbs causes an asymmetrical gait which can be a contributor of early onset osteoarthritis in the sound limbs. It has been shown that the moment transferred with conventional passive prostheses can be lowered in magnitude by aligning the tibia with ground reaction forces, but this limits the effectiveness of the device. With recent powered prosthetics designed to mimic the missing limb, power can be injected into the gait cycle, but can also be limited by this pressure threshold. This paper shows the results of calculations that suggest that altering the prosthetic ankle mechanism can reduce the socket interface moments by as much as 50%. This supports the development of an active non-anthropomorphic ankle prosthesis which reduces socket interface moments while still injecting substantial power levels into the gait cycle.

    Padur, Ashwini Aithal; Shanthakumar, Swamy Ravindra; Shetty, Surekha Devadas; Prabhu, Gayathri Sharath; Patil, Jyothsna

    2016-01-01

    Introduction Adequate knowledge on variant morphology of brachial plexus and its branches are important in clinical applications pertaining to trauma and surgical procedures of the upper extremity. Aim Current study was aimed to report variations of the branches of the lateral cord of brachial plexus in the axilla and their possible clinical complications. Materials and Methods Total number of 82 upper limbs from 41 formalin embalmed cadavers was dissected. Careful observation was made to note the formation and branching pattern of lateral cord. Meticulous inspection for absence of branches, presence of additional or variant branches and presence of abnormal communications between its branches or with branches of other cords was carried out. Results In the present study, we noted varied branching pattern of lateral cord in 6 out of 82 limbs (7%). In one of the limb, the median nerve was formed by three roots; two from lateral cord and one from medial cord. Two limbs had absence of lateral pectoral nerve supplemented by medial pectoral nerves. One of which had an atypical ansa pectoralis. In 2 upper limbs, musculocutaneous nerve was absent and in both cases it was supplemented by median nerve. In one of the limb, coracobrachialis had dual nerve supply by musculocutaneous nerve and by an additional branch from the lateral cord. Conclusion Variations of brachial plexus and its branches could pose both intraoperative and postoperative complications which eventually affect the normal sensory and motor functions of the upper limb.

  17. Non-traumatic brachial plexopathies, clinical, radiological and neurophysiological findings from a tertiary centre.

    Mullins, G M

    2012-02-03

    OBJECTIVE: To establish the clinical characteristics, aetiology, neuro-physiological characteristics, imaging findings and other investigations in a cohort of patients with non-traumatic brachial plexopathy (BP). METHODS: A 3-year retrospective study of patients with non-traumatic BP identified by electromyography (EMG) and nerve conduction studies (NCS). Clinical information was retrieved from patients\\' medical charts. RESULTS: Twenty-five patients were identified. Causes of BP included neuralgic amyotrophy (NA) (48%), neoplastic (16%), radiation (8%), post infectious (12%), obstetric (4%), rucksack injury (4%), thoracic outlet syndrome (4%) and iatrogenic (4%). Patients with NA presented acutely in 50%. The onset was subacute in all others. Outcome was better for patients with NA. All patients with neoplastic disease had a previous history of cancer. MRI was abnormal in 3\\/16 patients (18.8%). PET scanning diagnosed metastatic plexopathy in two cases. CONCLUSIONS: NA was the most common cause of BP in our cohort and was associated with a more favourable outcome. The authors note potentially discriminating clinical characteristics in our population that aid in the assessment of patients with brachial plexopathies. We advise NCS and EMG be performed in all patients with suspected plexopathy. Imaging studies are useful in selected patients.

  18. The role of ankle bracing for prevention of ankle sprain injuries.

    Gross, Michael T; Liu, Hsin-Yi

    2003-10-01

    Lateral ankle sprains are one of the most common injuries incurred in recreational and competitive athletics. These injuries have a significant impact in terms of cost, athletic participation, and activities of daily living. Prophylactic ankle braces are often used to reduce the risk of injury recurrence when individuals return to athletic participation. The purpose of this clinical commentary is to review the literature and provide our own experience relative to the use of prophylactic ankle bracing. Relatively high incidence rates of ankle sprain injury have been reported for basketball and soccer athletes, military trainees, and individuals with a previous history of ankle sprain injury. Semirigid and laced ankle braces have significantly reduced the incidence of initial and recurrent ankle sprain injuries in athletic and military samples. With few exceptions, these braces do not appear to affect functional performance adversely. The prophylactic use of semirigid ankle braces appears warranted to reduce the incidence of initial and, in particular, recurrent ankle sprain injuries for individuals who participate in activities that have the highest risk for these injuries. Additional research is needed to evaluate the many new braces that are available and in use and their influence on the incidence of ankle sprain injury and functional performance. PMID:14620786

  1. EFFECTS OF FATIGUE & GENDER ON PERONEAL REFLEXES AFTER ANKLE INVERSION

    Wilson, Erin Lawall

    2005-01-01

    An estimated 23,000 ankle injuries occur every day in the U.S. Ankle sprains account for 85% of all ankle injuries and inversion ankle sprains account for 85% of all ankle sprains. There is growing evidence that suggests gender and fatigue may increase the risk for inversion ankle sprains. Investigating the effects of fatigue and gender on peroneal reflex response after ankle inversion may help explain the differences in sprain rates with fatigue and gender. Therefore, the purpose of this stu...

  2. Conversion of ankle autofusion to total ankle replacement using the Salto XT revision prosthesis.

    Williamson, Emilie R C; Demetracopoulos, Constantine A; Ellis, Scott J

    2016-09-01

    Few reports in the literature have described the conversion of a surgically fused ankle to a total ankle replacement. The takedown of an autofusion and conversion to a prosthesis has not been described. We report the case of a patient with severe rheumatoid arthritis with an ankle autofusion fixed in equinus and severe talonavicular arthritis that was converted to ankle replacement using the Salto XT revision system. We describe the reasons why the decision was made to perform total ankle arthroplasty while concomitantly fusing the talonavicular joint, and discuss the rationale of the various surgical treatment options considered. We describe the clinical and radiographic outcomes achieved in this case. At 12 months post-operatively the patient reported significant reduction of pain, increased FAOS scores and had increased ankle range of motion. PMID:27502236

  3. MR imaging (at 1.5 T) of the brachial plexus

    Brachial plexus pathology can at times be difficult to visualize on CT, relative to normal structures, even with the aid of intravenous contrast. MR images of this area routinely give excellent anatomic delineation, due to the marked contrast in signal between fat in the axillary fossa, muscle, and pathology. The authors studied 15 patients at 1.5 T, eight normal and seven abnormal, with visualization of the trunks and cords. Some of the positive cases included metastatic deposits, cervical rib, severe vascular ectasia, a postangiography hematoma, etc. The distinct signal of pathologic tissue compared with the distinct signals of normal structures and the ability to evaluate vascular patency make MR imaging ideally suited in the evaluation of this region without the need of intravenous contrast

  4. Foot and Ankle Injuries in Runners.

    Tenforde, Adam S; Yin, Amy; Hunt, Kenneth J

    2016-02-01

    Foot and ankle injuries account for nearly one-third of running injuries. Achilles tendinopathy, plantar fasciopathy, and ankle sprains are 3 of the most common types of injuries sustained during training. Other common injuries include other tendinopathies of the foot and ankle, bone stress injuries, nerve conditions including neuromas, and joint disease including osteoarthritis. This review provides an evidence-based framework for the evaluation and optimal management of these conditions to ensure safe return to running participation and reduce risk for future injury.

    Imaging plays an essential role for the detection and analysis of pathologic conditions of the brachial plexus. Currently, several new techniques are used in addition to conventional 2D MR sequences to study the brachial plexus: the 3D STIR SPACE sequence, 3D heavily T2w MR myelography sequences (balanced SSFP = CISS 3D, True FISP 3D, bFFE and FIESTA), and the diffusion-weighted (DW) neurography sequence with fiber tracking reconstruction (tractography). The 3D STIR sequence offers complete anatomical coverage of the brachial plexus and the ability to slice through the volume helps to analyze fiber course modification and structure alteration. It allows precise assessment of distortion, compression and interruption of postganglionic nerve fibers thanks to the capability of performing maximum intensity projections (MIP) and multiplanar reconstructions (MPRs). The CISS 3D, b-SSFP sequences allow good visualization of nerve roots within the spinal canal and may be used for MR myelography in traumatic plexus injuries. The DW neurography sequence with tractography is still a work in progress, able to demonstrate nerves tracts, their structure alteration or deformation due to pathologic processes surrounding or located along the postganglionic brachial plexus. It may become a precious tool for the understanding of the underlying molecular pathophysiologic mechanisms in diseases affecting the brachial plexus and may play a role for surgical planning procedures in the near future.

  12. Primary ankle arthrodesis for neglected open weber B ankle fracture dislocation.

    Thomason, Katherine

    2014-07-01

    Primary ankle arthrodesis used to treat a neglected open ankle fracture dislocation is a unique decision. A 63-year-old man presented to the emergency department with a 5-day-old open fracture dislocation of his right ankle. After thorough soft tissue debridement, primary arthrodesis of the tibiotalar joint was performed using initial Kirschner wire fixation and an external fixator. Definitive soft tissue coverage was later achieved using a latissimus dorsi free flap. The fusion was consolidated to salvage the limb from amputation. The use of primary arthrodesis to treat a compound ankle fracture dislocation has not been previously described.

    2008-07-01

    Full Text Available Abstract Background Long-term patients with diabetes and peripheral neuropathy show altered foot biomechanics and abnormal foot loading. This study aimed at assessing muscle performance and ankle mobility in such patients under controlled conditions. Methods Forty six long-term diabetes patients with (DN and without (D peripheral neuropathy, and 21 controls (C were examined. Lower leg muscle performance and ankle mobility were assessed by means of a dedicated equipment, with the patient seated and the examined limb unloaded. 3D active ranges of motion and moments of force were recorded, the latter during maximal isometric contractions, with the foot blocked in different positions. Results All patients showed reduced ankle mobility. In the sagittal and transversal planes reduction vs C was 11% and 20% for D, 20% and 21% for DN, respectively. Dorsal-flexing moments were significantly reduced in all patients and foot positions, the highest reduction being 28% for D and 37% for DN. Reductions of plantar-flexing moments were in the range 12–15% for D (only with the foot blocked in neutral and in dorsal-flexed position, and in the range 10–24% for DN. In all patients, reductions in the frontal and transversal planes ranged 14–41%. Conclusion The investigation revealed ankle functional impairments in patients with diabetes, with or without neuropathy, thus suggesting that other mechanisms besides neuropathy might contribute to alter foot-ankle biomechanics. Such impairments may then play a role in the development of abnormal gait and in the onset of plantar ulcers.

  14. Prognostic value of thumb pain sensation in birth brachial plexopathy

    Carlos O. Heise

    2012-08-01

    Full Text Available OBJECTIVE: To evaluate the prognostic value of absent thumb pain sensation in newborns and young infants with birth brachial plexopathy. METHODS: We evaluated 131 patients with birth brachial plexopathy with less than two months of age. Pain sensation was evoked by thumb nail bed compression to evaluate sensory fibers of the upper trunk (C6. The patients were followed-up monthly. Patients with less than antigravity elbow flexion at six months of age were considered to have a poor outcome. RESULTS: Thirty patients had absent thumb pain sensation, from which 26 showed a poor outcome. Sensitivity of the test was 65% and specificity was 96%. CONCLUSION: Evaluation of thumb pain sensation should be included in the clinical assessment of infants with birth brachial plexopathy.

  15. Reversible brachial plexopathy following primary radiation therapy for breast cancer

    Salner, A.L.; Botnick, L.E.; Herzog, A.G.; Goldstein, M.A.; Harris, J.R.; Levene, M.B.; Hellman, S.

    Reversible brachial plexopathy has occurred in very low incidence in patients with breast carcinoma treated definitively with radiation therapy. Of 565 patients treated between January 1968 and December 1979 with moderate doses of supervoltage radiation therapy (average axillary dose of 5000 rad in 5 weeks), eight patients (1.4%) developed the characteristic symptoms at a median time of 4.5 months after radiation therapy. This syndrome consists of paresthesias in all patients, with weakness and pain less commonly seen. The symptom complex differs from other previously described brachial plexus syndromes, including paralytic brachial neuritis, radiation-induced injury, and carcinoma. A possible relationship to adjuvant chemotherapy exists, though the etiology is not well-understood. The cases described demonstrate temporal clustering. Resolution is always seen.

  17. A novel dynamic ankle-supinating device.

    Gutierrez, Gregory M; Kaminski, Thomas

    2010-02-01

    Lateral ankle sprains (LAS) are among the most common joint injuries, and although most are resolved with conservative treatment, others develop chronic ankle instability (AI). Considerable attention has been directed toward understanding the underlying causes of this pathology; however, little is known concerning the neuromuscular mechanisms behind AI. A biomechanical analysis of the landing phase of a drop jump onto a device that simulates the mechanism of a LAS may give insight into the dynamic restraint mechanisms of the ankle by individuals with AI. Furthermore, work evaluating subjects who have a history of at least one lateral ankle sprain, yet did not develop AI, may help elucidate compensatory mechanisms following a LAS event. Identifying proper neuromuscular control strategies is crucial in reducing the incidence of AI. PMID:20147765

  19. Postoperative MR study of the ankle

    20 patients with acute traumatic rupture of the anterior talofibular ligament and ligamental suture were studied postoperatively by MRI. MR results were correlated with stress X-ray studies. We found a normal anterior talofibular ligament in eight cases. However, stress X-ray images showed normal stability of the ankle joint in eighteen cases. In six patients the anterior talofibular ligament was thickened, in another six cases it could not be separated from scar tissue. Therefore MR imaging of ankle ligaments did not allow a diagnosis of their function. Nevertheless, sequelae of the ankle trauma such as osteochondrosis, exsudation into the ankle joint and tendovaginitis of the flexor muscles were sensitively visualised by MR. (orig.)

  1. Permanent upper trunk plexopathy after interscalene brachial plexus block.

    Avellanet, Merce; Sala-Blanch, Xavier; Rodrigo, Lidia; Gonzalez-Viejo, Miguel A

    2016-02-01

    Interscalene brachial plexus block (IBPB) has been widely used in shoulder surgical procedures. The incidence of postoperative neural injury has been estimated to be as high as 3 %. We report a long-term neurologic deficit after a nerve stimulator assisted brachial plexus block. A 55 year-old male, with right shoulder impingement syndrome was scheduled for elective surgery. The patient was given an oral dose of 10 mg of diazepam prior to the nerve stimulator assisted brachial plexus block. The patient immediately complained, as soon as the needle was placed in the interscalene area, of a sharp pain in his right arm and he was sedated further. Twenty-four hours later, the patient complained of severe shoulder and arm pain that required an increased dose of analgesics. Severe peri-scapular atrophy developed over the following days. Electromyography studies revealed an upper trunk plexus injury with severe denervation of the supraspinatus, infraspinatus and deltoid muscles together with a moderate denervation of the biceps brachii muscle. Chest X-rays showed a diaphragmatic palsy which was not present post operatively. Pulmonary function tests were also affected. Phrenic nerve paralysis was still present 18 months after the block as was dysfunction of the brachial plexus resulting in an inability to perform flexion, abduction and external rotation of the right shoulder. Severe brachial plexopathy was probably due to a local anesthetic having been administrated through the perineurium and into the nerve fascicles. Severe brachial plexopathy is an uncommon but catastrophic complication of IBPB. We propose a clinical algorithm using ultrasound guidance during nerve blocks as a safer technique of regional anesthesia. PMID:25744163

    Ankle sprain is a common sports injury and is often regarded as trivial by athletes and coaches. This epidemiological study was conducted among three categories of Hong Kong Chinese athletes: national teams, competitive athletes and recreational athletes. This study shows that as much as 73% of all athletes had recurrent ankle sprain and 59% of these athletes had significant disability and residual symptoms which led to impairment of their athletic performance. This study indicates that a pro...

  5. The diagnosis by computed tomography of brachial plexus lesions following radiotherapy for carcinoma of the breast

    The region of the brachial plexus in the root of neck and axilla was examined by computed tomography (CT) in 62 patients attending the Royal Marsden Hospital. Forty-two of these patients had been treated by surgery and subsequent radiotherapy for carcinoma of the breast. Computed tomography was able to identify varying grades of abnormality that were ascribed to radiation fibrosis. Twenty-eight patients had neurological symptoms affecting the arm or hand on the treated side and CT changes were seen in 96%. The grading and significance of these CT abnormalities is discussed. The patients had been treated by two different radiotherapy techniques (three-field and four-field) which utilised either a large or small treatment fraction. The higher grades of abnormality on CT were seen in 57% of those treated with the large fraction size and 27% of those treated with the small fraction size. However, the changes on CT did not relate to the different radiotherapy techniques. (author)

  7. Pediatric Stinger Syndrome: Acute Brachial Plexopathy After Minor Trauma.

    Quong, Whitney L; Hynes, Sally L; Arneja, Jugpal S

    2015-11-01

    The "stinger" or "burner" is a form of transient brachial plexopathy termed for its characteristic knife-like pain extending from the neck to the fingertips. Muscle weakness and paresthesia are oftentimes associated symptoms and are similarly temporary. Commonly observed in athletes of contact sports, the stinger results from high force trauma causing either traction/direct compression to the brachial plexus or extension/compression of the cervical nerve roots. We describe a pediatric case of a stinger in a 14-year-old boy, which was caused by a relatively low force trauma accident. Our management strategy and recommendations are discussed. PMID:26893985

  9. Ankle flexibility and injury patterns in dancers.

    Wiesler, E R; Hunter, D M; Martin, D F; Curl, W W; Hoen, H

    1996-01-01

    Lower-extremity injuries are common among dancers and cause significant absences from rehearsals and performances. For this study of lower-extremity injuries in 101 ballet and 47 modern dance students, injuries requiring medical attention sustained over 1 academic year were associated with the following data obtained at the beginning of the school year: ankle flexibility, sex, dance discipline, previous injury, body mass index, and years of training. Eighty-three of the 148 students (age range, 12 to 28 years) reported prior lower-limb injuries, the most common being ankle sprains (28% of all dancers). Previous leg injuries correlated significantly with lower dorsiflexion measurements and with more new injuries. Female students had greater ankle and first metatarsophalangeal flexibility. Modern dancers had greater ankle inversion. Ninety-four students sustained 177 injuries during the study, including 75 sprains or strains and 71 cases of tendinitis. Thirty-nine percent (N = 69) were ankle injuries; 18% (N = 33) were knee injuries; 23% (N = 40) were foot injuries; and 20% (N = 35) were either hip or thigh injuries. Sixty-seven percent (N = 78) of the injured students were ballet dancers. Age, years of training, body mass index, sex, and ankle range of motion measurement had no predictive value for injury; previous injury and dance discipline both correlated with increased risk of injury.

  10. Experimental evaluation of a portable powered ankle-foot orthosis.

    Shorter, Kenneth A; Li, Yifan; Morris, Emily A; Kogler, Géza F; Hsiao-Wecksler, Elizabeth T

    2011-01-01

    Ankle-foot orthoses (AFOs) ameliorate the impact of impairments to the lower limb neuromuscular motor system that affect gait. Emerging technologies provide a vision for fully powered, untethered AFOs. The portable powered AFO (PPAFO) provides both plantarflexor and dorsiflexor torque assistance via a bi-directional pneumatic rotary actuator. The system uses a portable pneumatic power source (bottle of compressed CO(2)) and embedded electronics to control foot motion during level walking. Experimental data were collected to demonstrate functionality from two subjects with bilateral impairments to the lower legs. These data demonstrated the PPAFO's ability to provide functional assistance during gait. The stringent design requirements of light weight, small size, high efficiency and low noise make the creation of daily wear assist devices challenging; but once such devices appear, they will present new opportunities for clinical treatment of gait abnormalities.

  12. [Brachial plexus. Long lasting neurological deficit following interscalene blockade of the brachial plexus].

    Funk, W; Angerer, M; Sauer, K; Altmeppen, J

    2000-07-01

    An interscalene block of the brachial plexus was combined with general anaesthesia for repair of a complex chronic lesion of the shoulder. The localisation of the plexus with electro-stimulation and the injection of Bupivacain 0.5% were accomplished easily and without painful sensations. 48 hours later the block was still partially present. Paraesthesia and a sensory and motor innervation deficit affected mainly the dorsal fascicle, but also areas innervated by the median and lateral fascicles. The deficit did not completely disappear for 18 month. The cause could have been due to direct traumatisation during blockade or operation, toxic action of the injected substance (Bupivacain 0.5%, 30 ml), distension of the plexus, a cervical syndrome or an aseptic plexitis, although a definite determination is not possible. However, the pattern of the lesion and the lack of pain during localisation of the plexus and injection favour traumatisation during the acromioplasty. PMID:10969388

  13. The prevalence and influence factors of inter-ankle systolic blood pressure difference in community population.

    Zhihong Zhang

    Full Text Available AIM: The aim of this study was to investigate the prevalence of interankle systolic blood pressure difference (sIAND and its influencing factors in community population. METHODS: This study included 2849 (65.1±9.4 y subjects. Blood pressure (BPs of four limbs was simultaneously measured with 4 electronic sphygmomanometers after 10 min rest in supine position. The difference of systolic BP (SBP between two ankles was calculated as DETASBP. The criterion for abnormal sIAND was ≥10 mmHg of absolute DeltaSBP, in which the criterion for 1o sIAND was 10-19 mmHg and for 2o sIAND was ≥20 mmHg. Age, gender, smoking, hypertension, family histories of hypertension and diabetes were recorded. Fasting blood glucose and lipids, circumference of hip and waist, and body mass index (BMI were measured. RESULTS: The SBP was higher in the right ankle than in the left ankle (158.9±21.8 vs 157.3±21.6 mmHg, P<0.05 and mean DeltaSBP was 6.08±6.26 mmHg. Similar difference was found in both genders. The prevalence of abnormal was 18.5%, in which, the prevalence 1o sIAND was 15.3% and that of 2o sIAND was 3.1%. Multivariate regression analysis showed that age, waist circumference and blood glucose level were the positive factors for DeltaSBP. The normal upper limit for DeltaSBP was 16.7 mmHg in this population, the prevalence of sIAND by≥16 mmHg was 5.8%. CONCLUSION: Aging, hypertension, obesity and abnormal glucose metabolism are positive factors for inter-ankle SBP difference.

  14. Interrater and intrarater reliability of photoplethysmography for measuring toe blood pressure and toe-brachial index in people with diabetes mellitus

    Scanlon Christopher

    2012-06-01

    Full Text Available Abstract Background A reliable tool to measure arterial flow to the feet in people with diabetes is required given that they are particularly prone to peripheral arterial disease. Traditionally, the ankle brachial index (ABI has been used to measure arterial circulation, but its application is limited due to calcification of larger arteries. More recently, toe pressure and the toe brachial index (TBI has been suggested as superior to ABI measurements because they assess smaller digital arteries less prone to arterial calcification. However, reliability studies for the clinical use of photoplethysmography (PPG in people with diabetes are lacking. Methods Sixty people with diabetes mellitus (35 males and 25 females, mean age 59.6 yrs consented to take part in the study. The majority (92% had type 2 diabetes and 8% had type 1 diabetes. Forty-three percent were diagnosed as having peripheral neuropathy when tested using a biothesiometer and 15% were current smokers (10 – 40/day. A podiatrist and a diabetes educator measured toe and brachial blood pressure independently and in a random order using PPG. These measurements were repeated again seven days later, and subsequently analysed with intraclass correlation coefficients (ICC, 95% confidence intervals (CI and standard error of measurement (SEM. Results The intrarater reliability of measuring toe pressures was excellent (ICC3,1 =0.78-0.79, SEM 8 mmHg and interrater reliability was also excellent (ICC2,2 = 0.93, SEM 4 mmHg. The intrarater reliability for measuring brachial pressures was generally poor (ICC3,1 = 0.40 – 0.42, SEM 19 mmHg and interrater reliability was fair-good (ICC2,2. 0.65, SEM 14 mmHg. The TBI intrarater reliability was fair-good (ICC3,1 = 0.51-0.72, SEM 0.08, whilst the interrater reliability of TBI was excellent (ICC2,2 = 0.85, SEM 0.07. Conclusions Based on these results, interrater and intrarater reliability of PPG is excellent for measuring toe

  15. MRI features of posterior ankle impingement syndrome in ballet dancers: a review of 25 cases

    AIM: To describe the magnetic resonance imaging (MRI) features of posterior ankle impingement syndrome (PAIS) in classical ballet dancers. MATERIALS AND METHODS: A retrospective review was undertaken of 25 MRI examinations of the ankle performed on 23 ballet dancers over a 26-month period. Images were examined for the presence of osseous and soft-tissue anatomical variants at the posterior ankle and imaging signs of PAIS. All patients presented with symptoms and signs suggestive of PAIS including posterior ankle pain, swelling and stiffness during plantar flexion. RESULTS: Anatomical variants predisposing to PAIS including as os trigonum and tuberosity arising from the superior calcaneum were clearly depicted. The most common imaging feature of PAIS in our series was high T2 signal posterior to the talocalcaneal joint indicating synovitis (n=25). Thickening of the posterior capsule (n=13) and tenosynovitis of flexor hallucis longus (n=17) were also common. An os trigonum was an infrequent finding (n=7). Bone marrow oedema, commonly in the posterior talus (n=10) or in a patchy distribution (n=10) was often noted. CONCLUSION: MRI is a useful diagnostic tool in PAIS, and in the present series, clearly demonstrates the anatomical variants and range of osseous and soft-tissue abnormalities associated with this condition. Prospective studies are needed to understand the significance and importance of individual MRI findings in producing the symptoms of PAIS

    Full Text Available BACKGROUND: The Ottawa ankle rules (OAR are clinical decision guidelines used to identify whether patients with ankle injuries need to undergo radiography. The OAR have been proven that their application reduces unnecessary radiography. They have nearly perfect sensitivity for identifying clinically significant ankle fractures. OBJECTIVES: The purpose of this study was to assess the applicability of the OAR in China, to examine their accuracy for the diagnosis of fractures in patients with acute ankle sprains, and to assess their clinical utility for the detection of occult fractures. METHODS: In this prospective study, patients with acute ankle injuries were enrolled during a 6-month period. The eligible patients were examined by emergency orthopedic specialists using the OAR, and then underwent ankle radiography. The results of examination using the OAR were compared with the radiographic results to assess the accuracy of the OAR for ankle fractures. Patients with OAR results highly suggestive of fracture, but no evidence of a fracture on radiographs, were advised to undergo 3-dimensional computed tomography (3D-CT. RESULTS: 183 patients with ankle injuries were enrolled in the study and 63 of these injuries involved fractures. The pooled sensitivity, specificity, positive predictive value and negative predictive value of the OAR for detection of fractures of the ankle were 96.8%, 45.8%, 48.4% and 96.5%, respectively. Our results suggest that clinical application of the OAR could decrease unnecessary radiographs by 31.1%. Of the 21 patients with positive OAR results and negative radiographic findings who underwent 3D-CT examination, five had occult fractures of the lateral malleolus. CONCLUSIONS: The OAR are applicable in the Chinese population, and have high sensitivity and modest specificity for the diagnosis of fractures associated with acute ankle injury. They may detect some occult fractures of the malleoli that are not visible on

  1. Axillary Brachial Plexus Blockade for the Reflex Sympathetic Dystrophy Syndrome.

    Ribbers, G. M.; Geurts, A. C. H.; Rijken, R. A. J.; Kerkkamp, H. E. M.

    1997-01-01

    Reflex sympathetic dystrophy syndrome (RSD) is a neurogenic pain syndrome characterized by pain, vasomotor and dystrophic changes, and often motor impairments. This study evaluated the effectiveness of brachial plexus blockade with local anaesthetic drugs as a treatment for this condition. Three patients responded well; three did not. (DB)

  2. Imaging diagnosis of neurogenic tumors of the brachial plexus

    To analyse the imaging characteristics of neurogenic tumors in the brachial plexus, six cases of neurogenic tumors of the brachial plexus were reported pathologically proved as schwannoma in 4 and neurofibroma in 2 cases. The plain films demonstrated the mass at the apex of lung in 3 cases, enlargement of cervical intervertebral foremen in 1. CT scan revealed that the average diameter of the masses was 4 cm, with spindle shape in 4, dumb-bell shape in 2 cases. The averaged CT value was similar to that of muscle on plain scan. The density of the tumor was higher than that of muscle and lower than that of vessels after contrast enhancement. On MRI T1W image, the masses were all hyperintense. Three schwannoma presented high signal intensity similar to CSF. The lesion demonstrated moderate enhancement after contrast administration in 1 case. Based on the location of the mass and its imaging features, diagnosis of neurogenic tumor of the brachial plexus could possibly be established before operation. MRI imaging is the imaging modality of choice in displaying the anatomy and the lesion of brachial plexus

  3. Morphological description of the brachial plexus in ocelot (Leopardus pardalis

    Kylma Lorena Saldanha Chagas

    2014-06-01

    Full Text Available The brachial plexus is formed by the ventral roots of the spinal nerves, which unite to form the nerve trunks. It is usually formed by contributions of the last three cervical nerves and the first two thoracic nerves. Due to the scarcity of information on neuroanatomy, this study aimed to determine the macroscopic morphology of the brachial plexus of the ocelot (Leopardus pardalis. In this work, we used two ocelot specimens from the area of the Paragominas Bauxite Mine, PA, Brazil/Empresa Terra LTDA, with permission from SEMA – BP Nos. 455/2009 and 522/2009. The animals were donated to the Research Laboratory of Animal Morphology (LaPMA, Federal Rural University of Amazonia (UFRA, after they were accidentally run over. They were fixed by intramuscular injection of 10% formaldehyde. After fixation, the animals were dissected, allowing visualization of the thoracic nerves, as well as the identification of the ventral rami of the cervical and thoracic spinal nerves forming the brachial plexus. The brachial plexus was found to be formed by four trunks, which originated the ventral branches of cervical spinal nerves C6, C7 and C8 and the first thoracic (T1. These trunks gave rise to the suprascapular, subscapular, musculocutaneous, axillary, radial, median, ulnar, thoracodorsal and lateral thoracic nerves.

  6. Analysis of the Effects of Normal Walking on Ankle Joint Contact Characteristics After Acute Inversion Ankle Sprain.

    Bae, Ji Yong; Park, Kyung Soon; Seon, Jong Keun; Jeon, Insu

    2015-12-01

    To show the causal relationship between normal walking after various lateral ankle ligament (LAL) injuries caused by acute inversion ankle sprains and alterations in ankle joint contact characteristics, finite element simulations of normal walking were carried out using an intact ankle joint model and LAL injury models. A walking experiment using a volunteer with a normal ankle joint was performed to obtain the boundary conditions for the simulations and to support the appropriateness of the simulation results. Contact pressure and strain on the talus articular cartilage and anteroposterior and mediolateral translations of the talus were calculated. Ankles with ruptured anterior talofibular ligaments (ATFLs) had a higher likelihood of experiencing increased ankle joint contact pressures, strains and translations than ATFL-deficient ankles. In particular, ankles with ruptured ATFL + calcaneofibular ligaments and all ruptured ankles had a similar likelihood as the ATFL-ruptured ankles. The push off stance phase was the most likely situation for increased ankle joint contact pressures, strains and translations in LAL-injured ankles. PMID:26077988

  7. Radiographic Evaluation of the Ankle Mortise

    Hamid Mirbagheri

    2010-05-01

    Full Text Available The ankle joint is the most frequently injured joint in adults. Decisions on management are usually based on clinical examination and interpretation of the x-rays. Stability of the ankle mortise relies on the configuration of the osseous structures and the ligaments. A basic radiographic examination consists of a mortise-view and a lateral view. Some add the AP-view. The Mortise view is an AP-view with 15-25 degrees endorotation of the foot. "nThe view clearly demonstrates both lateral and medial joint spaces. On a true AP-view the talus overlaps a portion of the lateral malleolus obscuring the lateral aspect of the ankle joint. However, the AP-view will give you an extra view on both malleoli from a different angle. The lateral radiograph of the ankle should include the base of the fifth metatarsal because of the frequency of fractures at this side that clinically mimic a fracture of the ankle.

  8. Acute injury of the ankle joint

    The diagnosis of lateral collateral ankle ligament trauma is based on patient history, clinical examination, and clinical stress tests. If the clinical stress test is positive, stress radiography could be performed. There is no consensus about the usefulness of stress radiography in acute ankle sprain, particularly about the cut-off talar tilt angle beyond which a two-ligament rupture would be certain, ranging from 5 to 30 . Today MRI is not used for this indication, although it allows, with controlled positioning of the foot and with defined sections, visualization of injured lateral collateral ankle ligaments. In ankle injuries, plain radiographs form the established basis of diagnostic imaging and can provide definitive answers in most cases. CT is used in complex fractures for complete visualization. MRI is the method of choice for several diagnostic problem cases, including occult fractures and post-traumatic avascular necrosis. In tendon injuries, MRI is important if ultrasound is not diagnostic. Generally, for the evaluation of acute ankle injuries, MRI is the most important second-step procedure when radiographs are nondiagnostic. (orig.)

  10. Brachial Neuritis With Phrenic Nerve Involvement in a Patient With a Possible Connective Tissue Disease.

    Subash, Meera; Patel, Gaurav; Welker, John; Nugent, Kenneth

    2014-01-01

    Background. Brachial neuritis (BN) is a rare inflammatory condition of peripheral nerves, usually involving the cervicobrachial plexus. These patients present with sudden onset of shoulder and arm pain that evolves into muscle weakness and atrophy.. Case Report. A 33-year-old woman presented with a 1-month history of diffuse pain in her thorax. She had no trauma or inciting incident prior to the onset of this pain and was initially treated for muscle spasms. The patient was seen in the emergency room multiple times and was treated with several courses of antibiotics for pneumonia on the basis of clinical symptoms and abnormal x-rays. The pleuritic chest pain persisted for at least 4 months, and the patient was eventually admitted for worsening pain and dyspnea. On physical examination, crackles were heard at both lung bases, and chest inspection revealed increased expansion in the upper thorax but poor expansion of the lower thorax and mild paradoxical respiration. "Sniff" test revealed no motion of the left hemidiaphragm and reduced motion on the right hemidiaphragm. Her computed tomography scan revealed bilateral atelectasis, more severe at the left base. She reported no symptoms involving her joints or skin or abdomen. Her presentation and clinical course are best explained by BN with a bilateral diaphragmatic weakness. However, she had a positive ANA, RF, anti-RNP antibody, and anti SS-A. Conclusion. Patients with BN can present with diffuse thoracic pain, pleuritic chest pain, and diaphragmatic weakness. Our patient may represent a case of connective tissue disease presenting with brachial plexus neuritis. PMID:26425609

    Botchu, Rajesh; Allen, Patricia; Rennie, Winston J

    2013-12-01

    High ankle sprains are difficult to diagnose and account for 10% of all ankle sprains. A high index of suspicion is essential for diagnosis. High ankle sprains are managed symptomatically, with prolonged rehabilitation. The posterior inferior tibiofibular ligament is the strongest syndesmotic ligament; isolated injury of it is rare. We present 3 cases of isolated posterior high ankle sprain and discuss the relevant anatomy, mechanism of injury, and management. PMID:24366808

    Context: Functional ankle instability has been defined in a variety of ways. Factors that are frequently used in this definition include a history of a severe ankle sprain, a history of multiple ankle sprains, and a recurrent feeling of instability or “giving way.” With all the variations in defining functional ankle instability, it becomes increasingly important to develop a more consistent framework for assessing this instability.

  15. RMI study and clinical correlations of ankle retinacula damage and outcomes of ankle sprain.

    Stecco, Antonio; Stecco, Carla; Macchi, Veronica; Porzionato, Andrea; Ferraro, Claudio; Masiero, Stefano; De Caro, Raffaele

    2011-12-01

    Recent studies reveal the role of the ankle retinacula in proprioception and functional stability of the ankle, but there is no clear evidence of their role in the outcomes of ankle sprain. 25 patients with outcomes of ankle sprain were evaluated by MRI to analyze possible damage to the ankle retinacula. Patients with damage were subdivided into two groups: group A comprised cases with ankle retinacula damage only, and group B those also with anterior talofibular ligament rupture or bone marrow edema. Both groups were examined by VAS, CRTA and static posturography and underwent three treatments of deep connective tissue massage (Fascial Manipulation technique). All evaluations were repeated after the end of treatment and at 1, 3 and 6 months. At MRI, alteration of at least one of the ankle retinacula was evident in 21 subjects, and a further lesion was also identified in 7 subjects. After treatment, VAS and CRTA evaluations showed a statistically significant decrease in values with respect to those before treatment (p stabilometric platform results. No significant difference was found between groups A and B. The initial benefit was generally maintained at follow-up. The alteration of retinacula at MRI clearly corresponds to the proprioceptive damage revealed by static posturography and clinical examination. Treatment focused on the retinacula may improve clinical outcomes and stabilometric data. PMID:21305286

  16. Subacute posteromedial impingement of the ankle in athletes: MR imaging evaluation and ultrasound guided therapy

    To describe the use of MR imaging and efficacy of ultrasound-guided steroid injection in the diagnosis and management of athletes with clinical posteromedial impingement of the ankle. A retrospective analysis of imaging findings on MR was undertaken in nine elite athletes with clinical posteromedial ankle impingement. MR studies from six professional athletes with posterolateral pain were also reviewed as an imaging control group. The two reviewing radiologists were blinded to the clinical details and the proportion of control and study subjects. The nine study athletes also underwent diagnostic ultrasound and ultrasound-guided injection of steroid and anaesthetic into the posteromedial capsular abnormality. Follow-up was by telephone interview. Posteromedial capsular thickening was seen only in athletes with posteromedial impingement (7/9). Posteromedial synovitis was present in all athletes with posteromedial impingement; however, posterior and posterolateral synovitis was also seen in these athletes. Mild posteromedial synovitis was present in two control athletes. Ultrasound identified abnormal posteromedial soft tissue thickening deep to tibialis posterior between the medial malleolus and talus in all nine athletes. After injection all athletes returned to their previous level of sport, with eight of the nine not experiencing any residual or recurrent symptoms. If MR imaging excludes significant coexistent abnormality, ultrasound can localise posteromedial soft tissue abnormality and guide injection therapy, allowing return to athletic activity without surgical intervention.

  20. Evaluation of Asymptomatic Peripheral Arterial Disease by Ankle-brachial Index in Patients with Concomitant Coronary Arterial Disease

    Hosein Vakili

    2012-12-01

    Full Text Available Background: Peripheral arterial disease is associated with adverse cardiovascular outcomes. As such, it is found that screening for peripheral arterial disease (PAD improves risk assessment. Thus, intensive risk factor modification and medical treatment in these patients are necessary. Objectives: The purpose of this study was to determine the prevalence of asymptomatic peripheral arterial disease in patients with concomitant coronary arterial disease. Methods: Asymptomatic peripheral arterial disease was investigated in 400 patients (60% males, 40% females, aged 59.7± 11.3 with a documented coronary arterial disease. Results: Among patients with documented CAD, 12% had asymptomatic PAD with the ABI ratio of less than 0.9. Conclusions: It is advisable to screen for PAD not only as a disease but also as a risk assessment method for atherosclerosis.

  1. Ankle Brachial Index Compared With Different Lipid Ratios to Predict Coronary Events in Patients with Coronary Artery Disease

    2014-02-01

    Multivariable adjusted relations revealed that HDL-C and #8804;34 Mg/dl significantly increased the risk of future UA, HDL-C and #8804;53 Mg/dl and sedentary life style increased the risk of MI. CONCLUSION: Multivariate adjusted relationships revealed that HDL-C and #8804;34 Mg/dl was a strong predictor of unstable angina pectoris after 15 months of follow up period. HDL-C and #8804;53 Mg/dl and physical inactivity were associated with increased risk of MI after 15 months. Of the lipid ratios the strongest predictors for developing future MI and unstable angina were TC/HDL-C and LDL-C/HDL-C. [TAF Prev Med Bull 2014; 13(1.000: 29-36

  2. Anterolateral ankle impingement: findings and diagnostic accuracy with ultrasound imaging

    The objective was to evaluate the findings and diagnostic accuracy of ultrasound in antero-lateral ankle impingement (ALI) with clinical and arthroscopic correlation. Seventeen elite footballers with chronic ankle pain were referred for ultrasound with a clinical diagnosis of ALI (n = 8) or a control condition (n = 9; lateral mechanical instability, osteochondral defect, intra-articular bodies and osteoarthritis). Ultrasound examination included the antero-lateral gutter for abnormal synovial tissue (synovitic lesion), lateral ligament integrity, tibiotalar joint and osseous spurs of the distal tibia and talus. Ultrasound findings were correlated with subsequent arthroscopic appearance. Ultrasound examination detected a synovitic mass in the antero-lateral gutter in all 8 footballers with clinical ALI (100%) and in 2 patients with a control diagnosis (22%). Arthroscopic correlation of antero-lateral synovitis and fibrosis was present in all 10 cases (100%). The synovitic lesion was seen at ultrasound as a nodular soft tissue mass of mixed echogenicity within the antero-lateral gutter, which extruded anteriorly with manual compression of the distal fibula against the tibia. Increased blood supply was detected using power Doppler imaging in only 1 patient. The synovitic lesion measured >10 mm in its maximum dimension in 7 footballers with clinical ALI and <10 mm in the control group. Additional ultrasound findings in patients with abnormal antero-lateral synovial tissue included an anterior talofibular ligament injury in all patients (n = 10), a tibiotalar joint effusion (n = 6) and osseous spurs (n = 4). Antero-lateral synovitic tissue was accurately identified at ultrasound in the absence of an effusion (n = 4). No synovitic lesion was detected at ultrasound or arthroscopy in the remaining 7 patients with a control diagnosis. Ultrasound is accurate in detecting synovitic lesions within the antero-lateral gutter, demonstrating associated ligamentous injuries and in

    2010-09-15

    Purpose: To evaluate late brachial plexopathy after primary chemoradiotherapy for locally advanced head and neck squamous cell carcinoma. Patients and Methods: Consecutive 43 disease-free patients were evaluated by a specifically developed 26-item questionnaire. Retrospectively, the brachial plexus was delineated and the dose-volume histograms were calculated. Results: After a median follow-up of 24 months, no radiation-induced brachial plexopathy was reported in these 43 patients. Conclusion: No radiation-induced brachial plexopathy was seen in the patient group, although 72.1% of the brachial plexuses received doses > 60 Gy. These findings should prompt further prospective studies and also stress the importance of trying to keep the doses to the brachial plexus as low as possible while covering the target volumes well.

  5. An anatomical study of double brachial arteries – a case report

    Krstonosic B

    2010-02-01

    Full Text Available Superficial brachial artery is one of the major variations of the arterial pattern in the upper limb. During routine anatomical dissection in our department, we observed a case of unilateral double brachial artery in a formalin-fixed female cadaver.Left axillary artery entered into the anterior region of the arm, where it branched into two brachial arteries – the superficial brachial artery (SBA, which was longer, tortuous and with a smaller caliber, and the brachial artery (BA, which was placed deep and medially. In the cubital fossa, covered with an aponeurosis of the biceps brachii muscle, both brachial arteries were connected with an anastomotic vessel. Under this anastomotic branch, in the forearm, SBA continued as the radial artery, whereas BA continued as the ulnar artery.Variations of the arterial pattern in the upper limb are undoubtedly of interest to the anatomists as well as to the clinicians.

  6. Retrograde transdorsal-to-plantar or transplantar-to-dorsal intraluminal re-entry treatment following unsuccessful subintimal angioplasty for below-the-ankle arterial occlusion

    Objective: To assess the technical feasibility and efficacy of transdorsal-to-plantar (TDP) or transplantar-to-dorsal (TPD) intraluminal re-entry procedure following unsuccessful subintimal angioplasty for the treatment of arterial occlusion below the ankle. Methods: TDP or TPD retrograde intraluminal re-entry angioplasty was carried out in 8 diseased limbs of 8 diabetic patients (5 males and 3 females, aged 62∼81 years with a mean age of 75±8 years), who were accompanied with chronic below-the-ankle arterial occlusive disease, after the standard transtibial subintimal angioplasty had failed. Both before and after the procedure the clinical symptoms, dorsal or plantar arterial pulse volume scores and ankle-brachial indexes (ABI) were determined in all patients, the results were compared and statistically analysed. During the follow-up period, the degree of pain relief, the healing of the wound, the salvage of the diseased limb and the restenosis occurrence of the target vessels were evaluated. Results: Of the total 8 patients, TDP or TPD retrograde intraluminal re-entry angioplasty was successfully performed in 5(62.5%). After the treatment the foot pain was markedly relieved, the median pulse volume scores and ankle-brachial indexes were increased from 0.60±0.55 and 0.32±0.20 before the procedure to 2.40±0.55 and 0.75±0.12 after the procedure, respectively (P<0.01 for both). At the end of the follow-up lasting for twelve months, the visual analogue scale was apparently improved, the scores decreased from preoperative 7.40±1.14 to 2.20±1.48 (P=0.002). Of two cases with intractable skin ulcer, the skin lesion was completely healed in one and was significantly decreased in size in another. No amputation surgery was needed in all successfully treated patients. Magnetic resonance angiography revealed that one target vessel developed re-stenosis. Conclusion: TDP and TDP retrograde intraluminal re-entry techniques are clinically feasible and effective for the

    Ankle sprain is a frequent injury in humans that results in pain, swelling and difficulty in walking on the affected ankle. Currently a suitable animal model resembling human ankle sprain is lacking. Here, we describe an animal ankle sprain model induced by ankle ligament injury (ALI) in rats. Cutting combinations of the lateral ankle ligament complex produced pain, edema and difficulty of weight bearing, thereby mimicking severe (grade III) ankle sprain in humans.

  8. Short-term ankle motor performance with ankle robotics training in chronic hemiparetic stroke

    Anindo Roy, PhD

    2011-05-01

    Full Text Available Cerebrovascular accident (stroke often results in impaired motor control and persistent weakness that may lead to chronic disability, including deficits in gait and balance function. Finding ways to restore motor control may help reduce these deficits; however, little is known regarding the capacity or temporal profile of short-term motor adaptations and learning at the hemiparetic ankle. Our objective was to determine the short-term effects of a single session of impedance-controlled ankle robot (“anklebot” training on paretic ankle motor control in chronic stroke. This was a double-arm pilot study on a convenience sample of participants with chronic stroke (n = 7 who had residual hemiparetic deficits and an equal number of age- and sex-matched nondisabled control subjects. Training consisted of participants in each group playing a target-based video game with the anklebot for an hour, for a total of 560 movement repetitions in dorsiflexion/plantar flexion ranges followed by retest 48 hours later. Task difficulty was adjusted to ankle range of motion, with robotic assistance decreased incrementally across training. Assessments included robotic measures of ankle motor control on unassisted trials before and after training and at 48 hours after training. Following exposure to the task, subjects with stroke improved paretic ankle motor control across a single training session as indexed by increased targeting accuracy (21.6 +/– 8.0 to 31.4 +/– 4.8, p = 0.05, higher angular speeds (mean: 4.7 +/– 1.5 degrees/s to 6.5 +/– 2.6 degrees/s, p 0.05 at 48 hours in both groups. Robust maintenance of motor adaptation in the robot-trained paretic ankle over 48 hours may be indicative of short-term motor learning. Our initial results suggest that the anklebot may be a flexible motor learning platform with the potential to detect rapid changes in ankle motor performance poststroke.

    To guide development of robotic lower limb exoskeletons, it is necessary to understand how humans adapt to powered assistance. The purposes of this study were to quantify joint moments while healthy subjects adapted to a robotic ankle exoskeleton and to determine if the period of motor adaptation is dependent on the magnitude of robotic assistance. The pneumatically-powered ankle exoskeleton provided plantar flexor torque controlled by the wearer’s soleus electromyography (EMG). Eleven naïve ...

    Our previous studies have demonstrated that some male patients suffering from brachial plexus injury, particularly brachial plexus root avulsion, show erectile dysfunction to varying degrees. However, the underlying mechanism remains poorly understood. In this study, we evaluated the erectile function after establishing brachial plexus root avulsion models with or without spinal cord injury in rats. After these models were established, we administered apomorphine (via a subcutaneous injection...

  11. Post-operative brachial plexus neuropraxia: A less recognised complication of combined plastic and laparoscopic surgeries

    2014-01-01

    This presentation is to increase awareness of the potential for brachial plexus injury during prolonged combined plastic surgery procedures. A case of brachial plexus neuropraxia in a 26-year-old obese patient following a prolonged combined plastic surgery procedure was encountered. Nerve palsy due to faulty positioning on the operating table is commonly seen over the elbow and popliteal fossa. However, injury to the brachial plexus has been a recently reported phenomenon due to the increasin...

    Background A prospective, double blind study was performed to compare the clinical effect of vertical infraclavicular and supraclavicular brachial plexus block using a nerve stimulator for upper limb surgery. Methods One hundred patients receiving upper limb surgery under infraclavicular or supraclavicular brachial plexus block were enrolled in this study. The infraclavicular brachial plexus block was performed using the vertical technique with 30 ml of 0.5% ropivacaine. The supraclavicular b...

  13. Delayed rupture of a pseudoaneurysm in the brachial artery of a burn reconstruction patient

    Lee, Jun Yong; Kim, Hyeri; Kwon, Ho; Jung, Sung-No

    2013-01-01

    A brachial artery pseudoaneurysm is a rare but serious condition that can be limb threatening. A number of reports have found that it may be the result of damage to the blood vessels around the brachial artery, either directly or indirectly, due to trauma or systemic diseases. We present our experience of delayed pseudoaneurysm rupture of the brachial artery in a rehabilitation patient with burns of the upper extremity who underwent fasciotomy and musculocutaneous flap coverage. We also provi...

  14. Technical note: the humeral canal approach to the brachial plexus.

    Frizelle, H P

    2012-02-03

    Many variations to the axillary approach to the brachial plexus have been described. However, the success rate varies depending on the approach used and on the definition of success. Recent work describes a new approach to regional anaesthesia of the upper limb at the humeral\\/brachial canal using selective stimulation of the major nerves. This report outlines initial experience with this block, describing the technique and results in 50 patients undergoing hand and forearm surgery. All patients were assessed for completeness of motor and sensory block. The overall success rate was 90 percent. Motor block was present in 80 percent of patients. Completion of the block was necessary in 5 patients. Two patients required general anaesthesia. The preponderance of ulnar deficiencies agrees with previously published data on this technique. No complications were described. Initial experience confirms the high success rate described using the Dupre technique. This technically straightforward approach with minimal complications can be recommended for regional anaesthesia of the upper limb.

  15. MR evaluation of the brachial plexus: Optimal imaging technique

    The authors compared four different reception coils, different degrees of T1 and T2 weighting, and different imaging planes for ability to depict normal brachial plexus anatomy at 1.5 T in 67 subjects. The use of loop gap resonators (axial opposed and butterfly) resulted in better resolution but a more limited field of view than did use of a rectangular surface coil (placed transversely behind the base of the neck) and the body coil. T1 and spin-density coronal images showed normal anatomy of the roots, trunks, and cords in a high proportion of cases. Double-echo (spin-density and T2-weighted) coronal imaging performed with a transversely oriented rectangular coil may be the best technique for imaging all three portions of the brachial plexus in the neck, retroclavicular, and axillary regions

  16. Brachial plexus lesions in patients with cancer: 100 cases

    In patients with cancer, brachial plexus signs are usually caused by tumor infiltration or injury from radiation therapy (RT). We analyzed 100 cases of brachial plexopathy to determine which clinical criteria helped differentiate tumor from radiation injury. Seventy-eight patients had tumor and 22 had radiation injury. Severe pain occurred in 80% of tumor patients but in only 19% of patients with radiation injury. The lower trunk was involved in 72% of the tumors. Seventy-eight percent of the radiation injuries affected the upper plexus (C5-6). Horner syndrome was more common in tumor, and lymphedema in radiation injury. The time from RT to onset of plexus symptoms, and the dose of RT, also differed

  17. Number of distal limb and brachial pressure measurements required when diagnosing peripheral arterial disease by laser Doppler flowmetry

    We examine the reliability of single and repeated blood pressure measurements at ankle, toe, and arm levels for the diagnosis of peripheral arterial disease (PAD) by laser Doppler flowmetry. Segmental pressures were measured in 200 patients with known or suspected PAD. Segmental indices were calculated using (1) one measurement [M-1], two measurements [M-2], or by a predefined reproducibility criterion (RC) as well as (2) by using one brachial blood-pressure (BBP-one) or correspondent to each segmental pressure (BBP-all) as reference. The agreement in diagnosis of PAD by Cohen's Kappa was κ = 0.930 when comparing RC to M-1, and κ = 0.977 when comparing RC to M-2. The same comparison showed excellent relative reliability for segmental indices (all intra-class correlation coefficients (ICC) ≥ 0.980). Diagnostic classification agreement for BBP-all versus BBP-one were κ = 0.831 for RC, κ = 0.804 for M-1, and κ = 0.847 for M-2. The relative reliability analysis showed excellent correlation in segmental indices (all ICC ≥ 0.957). The study shows minimal difference in segmental indices and diagnostic classification when comparing calculations based on the listed strategies. However, the study indicated that it is important to measure BBPs correspondent to each segmental pressure. (paper)

    2015-01-01

    A 27-year old woman was admitted to the emergency room after her left ankle rolled inward during a volleyball game. On physical examination a bony prominence on the lateral side of the left foot was noticeable, without neurovascular injury. An X-ray (anterior-posterior view) showed a subtalar dislocation without associated fractures. PMID:26420145

  19. Injury of the ankle joint ligaments

    The diagnosis of lateral collateral ankle ligament trauma is based on patient history, clinical examination and clinical stress tests. If the clinical stress test is positive, stress radiography can be performed. There is, however, no consensus about the usefulness of stress radiography in acute ankle sprain, and in particular about the cut-off talar tilt angle beyond which a two-ligament rupture would be certain, ranging from 5 to 30 . Today, magnetic resonance imaging (MRI) is not used in this area, although it does allow controlled positioning of the foot and defined section visualization of injured lateral collateral ankle ligaments. In acute and chronic sinus tarsi injuries, MRI forms the established basis for diagnostic imaging, and can provide a definitive answer in most cases. MRI is also the method of choice for chronic posttraumatic pain with anterolateral impingement after rupture of the anterior talofibular ligament. Generally, for the evaluation of acute ankle injuries, MRI has developed to be the most important second-step procedure when projection radiology is non-diagnostic. (orig.)

  20. Evaluation of brachial plexus injury by CT myelography

    Objective: To evaluate the diagnostic value of CT myelography (CTM) in brachial plexus injury. Methods: Twenty-seven patients with brachial plexus injury were examined by using cervical CTM with spiral scan and bone reconstruction algorithm. CT images were reviewed by the senior radiologists, who determined if the nerve root avulsion was presented. The criteria of diagnosing nerve root avulsion were loss of normal nerve root appearance in the Isovist filled thecal sac in consecutive CTM slices plus companion signs. The sensitivity, specificity, and accuracy of CTM in diagnosing nerve root injuries were calculated with operation findings and follow-up results as gold standard. Results: Direct sign of nerve root avulsion was the loss of normal nerve root defect seen in the Isovist filled thecal sac in consecutive CTM slices. Indirect signs included: (1) Pseudomeningocele bulge: The leak of Isovist into nerve root sheath, and extended into foramina; (2) Arachnoid cyst: displacement of spinal cord; (3) Dissymmetry of subarachnoid cavity: deformity of thecal sac, partially lack of Isovist into arachnoid space; (4) Non-integrity of dural cap sule wall: one side of cap sule cavity was obstructed. Part of the surface of spinal cord was exposed. Brachial plexus injury could be diagnosed by direct sign with one of the indirect signs. Of the 27 patients (128 nerve roots), 91 nerve root avulsions were found on CTM, and 37 was found normal. Compared with operation findings, 84 were true positive, 7 false positive, 34 true negative, and 3 false negative. Based on these results, the sensitivity, specificity, and accuracy were 96.6%, 82.9%, and 92.2%, respectively. Conclusion: CTM is accurate in detecting nerve root avulsion of brachial plexus.

  1. Delayed presentation of a traumatic brachial artery pseudoaneurysm.

    Forde, James C

    2009-09-01

    Delayed presentation of a brachial artery pseudoaneurysm following penetrating trauma is infrequently reported. We report the case of a 23-year-old male who presented three months following a penetrating trauma to his antecubital fossa with a sudden exacerbation of swelling and tenderness of his elbow. Doppler ultrasound and computed tomography arteriography confirmed the presence of a large pseudoaneurysm. Surgical reconstruction was performed using the long saphenous vein as an interposition vein graft, restoring normal arterial circulation.

  4. Trapezius transfer to treat flail shoulder after brachial plexus palsy

    Diaz Humberto

    2007-01-01

    Full Text Available Abstract Background After severe brachial palsy involving the shoulder, many different muscle transfers have been advocated to restore movement and stability of the shoulder. Paralysis of the deltoid and supraspinatus muscles can be treated by transfer of the trapezius. Methods We treated 10 patients, 8 males and 2 females, by transfer of the trapezius to the proximal humerus. In 6 patients the C5 and C6 roots had been injuried; in one C5, C6 and C7 roots; and 3 there were complete brachial plexus injuries. Eight of the 10 had had neurosurgical repairs before muscle transfer. Their average age was 28.3 years (range 17 to 41, the mean delay between injury and transfer was 3.1 years (range 14 months to 6.3 years and the average follow-up was 17.5 months (range 6 to 52, reporting the clinical and radiological results. Evaluation included physical and radiographic examinations. A modification of Mayer's transfer of the trapezius muscle was performed. The principal goal of this work was to evaluate the results of the trapezius transfer for flail shoulder after brachial plexus injury. Results All 10 patients had improved function with a decrease in instability of the shoulder. The average gain in shoulder abduction was 46.2°; the gain in shoulder flexion average 37.4°. All patients had stable shoulder (no subluxation of the humeral head on radiographs. Conclusion Trapezius transfer for a flail shoulder after brachial plexus palsy can provide satisfactory function and stability.

  5. Metastatic Brachial Plexopathy in a Case of Recurrent Breast Carcinoma Demonstrated on {sup 18}F-FDG PET/CT

    referred for magnetic resonance imaging (MRI) to demonstrate the brachial plexus involvement. Coronal diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) revealed a mass in the right axilla, with a b value of 1,000, infiltrating the cord and branches of the right brachial plexus visualised as linear hyperintensities (Fig. 1c, arrow). Brachial plexopathy in breast cancer patients can be metastatic (because major lymph drainage routes for the breast course through the axilla) or radiation induced, the former being the commoner of the two. Differentiation between the two pathologies is important for appropriate treatment planning. {sup 18}F-FDG PET/CT is a useful tool in the evaluation of patients with recurrent or metastatic breast cancer. Recognition of the pattern of brachial plexus involvement is thus essential for accurate interpretation of the {sup 18}F-FDG PET/CT study. To date, two case reports and one small case series have demonstrated the feasibility of PET for confirming metastatic brachial plexopathy when MRI was suspicious of the same or when the patient was symptomatic for the same. This case highlights the possibility of metastatic brachial plexopathy even when the patient may not be overtly symptomatic for the same. The typical pattern as seen on MIP and coronal images is linear, extending from the superomedial aspect (supra/infraclavicular) to the lateral aspect of axilla closely related to the subclavian/axillary vessels). The commonest finding on computed tomography (CT) is that of an axillary mass, but may range from no remarkable abnormality to minimal thickening. Moreover, CT would not be able to differentiate metastatic from radiation plexopathy. MRI is the first-line imaging modality for evaluating brachial plexopathy and can delineate both normal and abnormal anatomy of the brachial plexus, with the ability to differentiate nerves from the surrounding vessels and soft tissue with greater detail than CT. In this case

    Full Text Available This presentation is to increase awareness of the potential for brachial plexus injury during prolonged combined plastic surgery procedures. A case of brachial plexus neuropraxia in a 26-year-old obese patient following a prolonged combined plastic surgery procedure was encountered. Nerve palsy due to faulty positioning on the operating table is commonly seen over the elbow and popliteal fossa. However, injury to the brachial plexus has been a recently reported phenomenon due to the increasing number of laparoscopic and robotic procedures. Brachial plexus injury needs to be recognised as a potential complication of prolonged combined plastic surgery. Preventive measures are discussed.

  7. Novel Axillary Approach for Brachial Plexus in Robotic Surgery: A Cadaveric Experiment

    2014-01-01

    Full Text Available Brachial plexus surgery using the da Vinci surgical robot is a new procedure. Although the supraclavicular approach is a well known described and used procedure for robotic surgery, axillary approach was unknown for brachial plexus surgery. A cadaveric study was planned to evaluate the robotic axillary approach for brachial plexus surgery. Our results showed that robotic surgery is a very useful method and should be used routinely for brachial plexus surgery and particularly for thoracic outlet syndrome. However, we emphasize that new instruments should be designed and further studies are needed to evaluate in vivo results.

    Brachial neuritis is a rare disease in children, affecting mainly the lower motor neurons of the brachial plexus and/or individual nerves or nerve branches. We report a case of idiopathic brachial plexus neuritis in a 2½-year-old female child admitted with acute respiratory distress and given antibiotic therapy following which she developed weakness of the left hand. She was diagnosed as a case of idiopathic brachial plexus neuritis and was given supportive care. Although, the association with antibiotic therapy in this case could be incidental, indeed it is intriguing and requires further studies. PMID:25624937

  10. Continuous shoulder analgesia via an indwelling axillary brachial plexus catheter.

    Reuben, S S; Steinberg, R B

    2000-09-01

    Continuous interscalene brachial plexus blockade can provide anesthesia and analgesia in the shoulder region. Difficulty accessing the interscalene space and premature displacement of interscalene catheters may preclude their use in certain situations. We present two case reports in which a catheter was advanced from the axilla along the brachial plexus sheath to the interscalene space to provide continuous cervicobrachial plexus analgesia. In the first case report, previous neck surgery made the anatomic landmarks for performing an interscalene block very difficult. An epidural catheter was advanced from the axillary brachial plexus sheath to the interscalene space under fluoroscopic guidance. This technique provided both intraoperative analgesia for shoulder surgery as well as 24-hour postoperative analgesia by an infusion of 0.125% bupivacaine. In the second case report, a catheter was inserted in a similar fashion from the axillary to the interscalene space to provide 14 days of continuous analgesia in the management of complex regional pain syndrome. We have found that this technique allows us to secure the catheter more easily than with the traditional interscalene approach and thus prevents premature dislodgment. This approach may be a suitable alternative when either an interscalene or an infraclavicular catheter may not be inserted. PMID:11090734

  11. Neurolysis and myocutaneous flap for radiation induced brachial plexus neuropathy

    Surgical treatment for radiation induced brachial plexus neuropathy is difficult. We followed 9 patients of radiation induced brachial plexus neuropathy who were surgically treated with neurolysis and myocutaneous flap coverage. Their ages ranged from 29 to 72 years old. Their diagnoses were breast cancer in 6 patients, lingual cancer in 1, thyroid cancer in 1 and malignant lymphoma in 1. Total dose of radiation ranged from 44 to 240 Gy. Interval from radiation therapy to our surgery ranged from 1 to 18 years (mean 6.7 years). Chief complaints were dysesthesia in 9 patients, motor weakness in 7 patients and dullach in scar formation of radiated skin in 7 patients. Preoperative neural functions were slight palsy in 1, moderate palsy in 5 and complete palsy in 3. In surgical treatment, neurolysis of the brachial plexus was done and it was covered by latissimus dorsi myocutaneous flap. We evaluated about dysesthesia and motor recovery after treatment for neuropathy. Follow up periods ranged from 1 to 11 years (average in 5 years). Dysesthesia improved in 6 patients and got worse in 3 patients. Motor weakness recovered in only 2 patients and got worse in 7 patients. From our results, intolerable dysesthesia which was first complaint of these patients improved. But motor function had not recovered. Our treatment was thought to be effective for extraneural factor like an compression neuropathy by scar formation and poor vascularity. But it was not effective for intraneural damage by radiation therapy. (author)

  15. A multimodal approach to ankle instability: Interrelations between subjective and objective assessments of ankle status in athletes.

    Golditz, Tobias; Welsch, Goetz H; Pachowsky, Milena; Hennig, Friedrich F; Pfeifer, Klaus; Steib, Simon

    2016-03-01

    The aim of this retrospective cohort study is to investigate the association between different subjective and objective assessments of ankle function in a population of athletes with or without functional ankle instability (FAI). 29 athletes with a history of ankle spraining were divided into two groups according to their ankle status: 16 with FAI (initial ankle sprain with residual functional instability) (age 24.6 ± 3.1 years), and 13 COPERS (initial ankle sprain without residual instability) (age 25.3 ± 4.4 years). The assessment of each individual's ankle function was based on three approaches: The "functional-ankle-ability-measure" (FAAM) assessing subjective ankle functionality, measures of sensorimotor control as objective functional measurements and MRI-based T2-mapping as a quantitative marker of compositional joint status. Pearson's product-moment-correlation coefficient, student's t-test and analysis-of-variance were used for statistical analysis. Significant group differences existed for subjective ankle function (FAAM, p = 0.04) and MRI-data mainly in the medial compartment of the ankle joint (p ≤ 0.05). We found unique associations between T2-mapping results and sensorimotor scores in the COPER (r = -0.756-0.849), and "FAI"-group (r = 0.630-0.657). The location and magnitude differed between groups. No correlations existed between these measures and the FAAM. This exploratory study provides preliminary evidence for potential interrelations between various diagnostic measures of ankle function and structure in individuals with and without FAI. We found associations between MRI-results and selected measures of sensorimotor control, indicating a potential link between loss of ankle function and early joint degeneration. Despite these interrelations, each of the different assessment options appears to contain unique information on ankle functionality important in a clinical assessment. PMID:26309042

  17. Design of a simple, lightweight, passive-elastic ankle exoskeleton supporting ankle joint stiffness

    Kim, Seyoung; Son, Youngsu; Choi, Sangkyu; Ham, Sangyong; Park, Cheolhoon

    2015-09-01

    In this study, a passive-elastic ankle exoskeleton (PEAX) with a one-way clutch mechanism was developed and then pilot-tested with vertical jumping to determine whether the PEAX is sufficiently lightweight and comfortable to be used in further biomechanical studies. The PEAX was designed to supplement the function of the Achilles tendon and ligaments as they passively support the ankle torque with their inherent stiffness. The main frame of the PEAX consists of upper and lower parts connected to each other by tension springs (N = 3) and lubricated hinge joints. The upper part has an offset angle of 5° with respect to the vertical line when the springs are in their resting state. Each spring has a slack length of 8 cm and connects the upper part to the tailrod of the lower part in the neutral position. The tailrod freely rotates with low friction but has a limited range of motion due to the stop pin working as a one-way clutch. Because of the one-way clutch system, the tension springs store the elastic energy only due to an ankle dorsiflexion when triggered by the stop pin. This clutch mechanism also has the advantage of preventing any inconvenience during ankle plantarflexion because it does not limit the ankle joint motion during the plantarflexion phase. In pilot jumping tests, all of the subjects reported that the PEAX was comfortable for jumping due to its lightweight (approximately 1 kg) and compact (firmly integrated with shoes) design, and subjects were able to nearly reach their maximum vertical jump heights while wearing the PEAX. During the countermovement jump, elastic energy was stored during dorsiflexion by spring extension and released during plantarflexion by spring restoration, indicating that the passive spring torque (i.e., supportive torque) generated by the ankle exoskeleton partially supported the ankle joint torque throughout the process.

  18. Acute and chronic lateral ankle instability in the athlete.

    Chan, Keith W; Ding, Bryan C; Mroczek, Kenneth J

    2011-01-01

    Ankle sprain injuries are the most common injury sustained during sporting activities. Three-quarters of ankle injuries involve the lateral ligamentous complex, comprised of the anterior talofibular ligament (ATFL), the calcaneofibular ligament (CFL), and the posterior talofibular ligament (PTFL). The most common mechanism of injury in lateral ankle sprains occurs with forced plantar flexion and inversion of the ankle as the body's center of gravity rolls over the ankle. The ATFL followed by the CFL are the most commonly injured ligaments. Eighty percent of acute ankle sprains make a full recovery with conservative management, while 20% of acute ankle sprains develop mechanical or functional instability, resulting in chronic ankle instability. Treatment of acute ankle sprains generally can be successfully managed with a short period of immobilization that is followed by functional rehabilitation. Patients with chronic ankle instability who fail functional rehabilitation are best treated with a Brostrom-Gould anatomic repair or, in those patients with poor tissue quality or undergoing revision surgery, an anatomic reconstruction.

  19. The value of spiral CT scan on fracture of ankle joint and tarsal bones

    Objective: To study the value of spiral CT scan on the fracture of ankle joint and tarsal bones. Methods: 43 cases with the fracture of ankle joint and tarsal bones were collected and analyzed. All the cases were examined by plain film radiography and spiral CT thin slice scan. Multi-planar reformation (MPR), surface shaded display (SSD) and other techniques of image post-processing were performed in 35 cases of them. Results: Spiral CT scan could demonstrate more fractures than plain film radiography in 28 cases(65.1%). There are 15 cases (34.9%) which are normal in plain film radiography but abnormal in Spiral CT scan. Spiral CT could demonstrate the different length, width, direction and number of linear low density shadow. SSD and MPR were performed again in the cases with avulsion fracture and fragmental fracture to demonstrate the fracture direction and the shape, size and location of fragments more clearly. Conclusion: Spiral CT thin slice scan with image post-processing techniques can play an important role in fracture of ankle joint and tarsal bones. (authors)

  20. Predicting functional recovery after acute ankle sprain.

    Sean R O'Connor

    Full Text Available INTRODUCTION: Ankle sprains are among the most common acute musculoskeletal conditions presenting to primary care. Their clinical course is variable but there are limited recommendations on prognostic factors. Our primary aim was to identify clinical predictors of short and medium term functional recovery after ankle sprain. METHODS: A secondary analysis of data from adult participants (N = 85 with an acute ankle sprain, enrolled in a randomized controlled trial was undertaken. The predictive value of variables (age, BMI, gender, injury mechanism, previous injury, weight-bearing status, medial joint line pain, pain during weight-bearing dorsiflexion and lateral hop test recorded at baseline and at 4 weeks post injury were investigated for their prognostic ability. Recovery was determined from measures of subjective ankle function at short (4 weeks and medium term (4 months follow ups. Multivariate stepwise linear regression analyses were undertaken to evaluate the association between the aforementioned variables and functional recovery. RESULTS: Greater age, greater injury grade and weight-bearing status at baseline were associated with lower function at 4 weeks post injury (p<0.01; adjusted R square=0.34. Greater age, weight-bearing status at baseline and non-inversion injury mechanisms were associated with lower function at 4 months (p<0.01; adjusted R square=0.20. Pain on medial palpation and pain on dorsiflexion at 4 weeks were the most valuable prognostic indicators of function at 4 months (p< 0.01; adjusted R square=0.49. CONCLUSION: The results of the present study provide further evidence that ankle sprains have a variable clinical course. Age, injury grade, mechanism and weight-bearing status at baseline provide some prognostic information for short and medium term recovery. Clinical assessment variables at 4 weeks were the strongest predictors of recovery, explaining 50% of the variance in ankle function at 4 months. Further

    Kim, Ki-Jong; Jun, Hyun-Ju; Heo, Myoung

    2015-11-01

    [Purpose] The objective of this study was to examine the effects of a training program using the Nintendo Wii Fit Plus on the ankle muscle strengths of subjects with functional ankle instability. [Subjects and Methods] This study was conducted using subjects in their 20s who had functional ankle instability. They were randomized to a strengthening training group and a balance training group with 10 subjects in each, and they performed an exercise using Nintendo Wii Fit Plus for 20 minutes. In addition, every participant completed preparation and finishing exercises for 5 minutes, respectively. [Results] The muscle strengths after conducting plantar flexion and dorsiflexion significantly increased at the angular velocities of 60° and 120° in the strengthening training group. Furthermore, the muscle strengths after conducting plantar flexion, dorsiflexion, eversion, and inversion significantly increased at the angular velocities of 60° and 120° in the balance training group. [Conclusion] The balance training group using Nintendo Wii Fit Plus showed better results than the strengthening training group. Consequently, it is recommended to add the balance training program of the Nintendo Wii Fit Plus to conventional exercise programs to improve ankle muscle strength in functional ankle instability at a low cost.

  3. Disturbed function of the brachial plexus after irradiation for a malignant disease

    In reference to the case history of a woman aged 26 years in whom approx. 7 years after irradiation for Hodgkin's disease, lesions of the upper roots of the brachial plexus (Erb-Duchenne type) developed, the differential diagnosis is discussed of brachial plexus lesions in the presence of a recurrent malignant disease or as the consequence of irradiation.

    An interscalene brachial plexus block is an effective means of providing anesthesia-analgesia for shoulder surgery. However, it has a multitude of potential side effects such as phrenic nerve block. We report a case of a patient who developed atelectasis of the lung, and pleural effusion manifested as chest discomfort during a continuous interscalene brachial plexus block for postoperative analgesia.

  5. On the cause of brachial plexus neuropathy after radiation therapy of patients with mamma carcinoma

    Radiation therapy is often considered as cause of brachial plexus neuropathy in patients with mamma carcinoma. One case (in which metastases could be established as specific cause) is used as specific example for the possible differential diagnosis of brachial plexus neuropathy. (orig.)

    2013-01-01

    Brachial plexus schwannomas are rare tumors. They are benign nerve sheath tumors and only about 5% of Schwannoma arise from the brachial plexus. They pose a great challenge to surgeons due to their rare occurrence and complex anatomical location. We present two cases who presented with a supraclavicular swelling, that were proven to be schwannoma on histopathology.

    2014-01-01

    Our previous studies have demonstrated that some male patients suffering from brachial plexus injury, particularly brachial plexus root avulsion, show erectile dysfunction to varying degrees. However, the underlying mechanism remains poorly understood. In this study, we evaluated the erectile function after establishing brachial plexus root avulsion models with or without spinal cord injury in rats. After these models were established, we administered apomorphine (via a sub-cutaneous injection in the neck) to observe changes in erectile function. Rats subjected to simple brachial plexus root avulsion or those subjected to brachial plexus root avulsion combined with spinal cord injury had signiifcantly fewer erections than those subjected to the sham operation. Expression of neuronal nitric oxide synthase did not change in brachial plexus root avulsion rats. However, neuronal nitric oxide synthase expression was signiifcantly decreased in brachial plexus root avulsion + spinal cord injury rats. These ifndings suggest that a decrease in neuronal nitric oxide synthase expression in the penis may play a role in erectile dysfunction caused by the combi-nation of brachial plexus root avulsion and spinal cord injury.

    Brachial plexuses of 110 healthy volunteers were examined using high resolution color Doppler ultrasound. Ultrasonic characteristics and anatomic variation in the intervertebral foramen, interscalene, supraclavicular and infraclavicular, as well as the axillary brachial plexus were investigated. Results confirmed that the normal brachial plexus on cross section exhibited round or elliptic hypoechoic texture. Longitudinal section imaging showed many parallel linear hypo-moderate echoes, with hypo-echo. The transverse processes of the seventh cervical vertebra, the scalene space, the subclavian artery and the deep cervical artery are important markers in an examination. The display rates for the interscalene, and supraclavicular and axillary brachial plexuses were 100% each, while that for the infraclavicular brachial plexus was 97%. The region where the normal brachial plexus root traversed the intervertebral foramen exhibited a regular hypo-echo. The display rate for the C5-7 nerve roots was 100%, while those for C8 and T1 were 83% and 68%, respectively. A total of 20 of the 110 subjects underwent cervical CT scan. High-frequency ultrasound can clearly display the outline of the transverse processes of the vertebrae, which were consistent with CT results. These results indicate that high-frequency ultrasound provides a new method for observing the morphology of the brachial plexus. The C7 vertebra is a marker for identifying the position of brachial plexus nerve roots.

  9. Modulation of ankle stiffness during postural sway.

    Lang, Christopher B; Kearney, Robert E

    2014-01-01

    Ankle stiffness is a nonlinear, time-varying system which contributes to the control of human upright stance. This study sought to examine the nature of the contribution of stiffness to postural control by determining how intrinsic and reflex stiffnesses varied with sway. Subjects were instructed to stand quietly on a bilateral electro-hydraulic actuator while perturbations were applied about the ankle. Subjects performed three types of trials: normal stance, forward lean, and backward lean. Position, torque, and EMGs from the tibialis anterior and triceps surae were recorded. Background torque, intrinsic stiffness and reflex stiffness were calculated for each perturbation. Intrinsic and reflex stiffnesses were heavily modulated by postural sway. Moreover, they were modulated in a complimentary manner; intrinsic stiffness was lowest when reflex gain was highest, and vice versa. These findings suggest that intrinsic stiffness is modulated simultaneously with reflex stiffness to optimize the control of balance. PMID:25570884

  10. MR arthrography of the ankle joint

    Due to its superior soft tissue contrast conventional MRI is the imaging method of choice in the evaluation of ankle joint disorders. Conventional MR imaging can accurately demonstrate normal or acutely injured ligaments; however, in subacute and chronic injury joint fluid necessary for delineation of injured ligaments is absent and MR arthrography should be performed. MR arthrography uses the intraarticular injection of contrast material to distend the joint, yielding improved discrimination of intraarticular structures. This joint distension with MR arthrography is also helpful in the staging of osteochondritis dissecans, since in cases of unstable lesions tracking of contrast material into the interface can be more easily demonstrated. Finally, high contrast and joint distension by MR arthrography improves the detection of intraarticular loose bodies, which often require surgery. MR artrography, although invasive, may provide additional information in various ankle joint disorders. (orig.)

    2015-04-01

    Ankle sprains are orthopedic clinical common disease, accounting for joint ligament sprain of the first place. If treatment is not timely or appropriate, the joint pain and instability maybe develop, and even bone arthritis maybe develop. The mechanism of injury of ankle joint, anatomical basis has been fully study at present, and the diagnostic problem is very clear. Along with the development of science and technology, biological modeling and three-dimensional finite element, three-dimensional motion capture system,digital technology study, electromyographic signal study were used for the basic research of sprain of ankle. Biomechanical and kinematic study of ankle sprain has received adequate attention, combined with the mechanism research of ankle sprain,and to explore the the biomechanics and kinematics research progress of the sprain of ankle joint. PMID:26072625

  12. Diagnosis of ligament injuries in the superior ankle joint

    Nearly 40 years after ankle arthrography was first introduced, the anterior and inversion stress views of the ankle are still widely preferred as a noninvasive method of evaluating ligament injuries in the upper ankle. We consider the stress test, bilaterally performed using a standardized stress apparatus, as a basic examination by which to differentiate between slight and severe sprain. Intensive muscel splinting due to painful swelling can sometimes be treated by injection of local anesthetic. Like many authors, we perform ankle arthrography in cases where there is a significant difference between the clinical findings and the stress test. The technique of ankle arthrography can be readily learned and is extremely accurate in delineating the extent of ligamentous injury produced by moderate or severe ankle sprains. It can be performed in any X-ray department. (orig.)

  13. Injuries of the lateral collateral ligaments of the ankle: assessment with MR imaging

    The aim of this study was to evaluate the ability of MRI to display injuries of the lateral collateral ligamentous complex in patients with an acute ankle distorsion trauma. The MR examinations of 36 patients with ankle pain after ankle distorsion were evaluated retrospectively without knowledge of clinical history, outcome and/or operative findings. The examinations were performed on a 1.5-T whole-body imager using a flexible surface coil. The signs for ligamentous abnormality were as follows: complete or partial discontinuity, increased signal within, and irregularity and waviness of the ligament. The results were compared with operative findings in 18 patients with subsequent surgical repair. Eighteen patients with conservative therapy had a follow-up MR examination after 3 months. There was 1 sprain, 3 partial and 32 complete tears of the anterior talofibular ligament, and 5 sprains, 5 partial, and 7 complete tears of the calcaneofibular ligament. There were no lesions of the posterior talofibular ligament. Compared with surgery, MRI demonstrated in 18 of 18 cases the exact extent of anterior talofibular ligament injuries and underestimated the extent in 2 of 8 cases of calcaneofibular ligament injury. In patients with follow-up MRI after conservative therapy, a thickened band-like structure was found along the course of the injured ligament in 17 of 18 cases. The absence of ligament repair after conservative treatment was confirmed during operative revision in one case. The MRI technique allows for grading of the extent of injury of the lateral collateral ligamentous complex after acute ankle strain. It seems to be suitable for monitoring the healing process after conservative-functional treatment of ligament tears. (orig.)

  15. Clinical and electrodiagnostic findings in breast cancer patients with radiation-induced brachial plexus neuropathy

    The clinical and neurophysiological characteristics of radiation-induced brachial plexopathy (RBP) were assessed in 79 breast cancer patients without signs of recurrent disease at least 60 months after radiotherapy (RT). Clinically, 35% (95% confidence limits: 25-47%) had RBP. Fifty percent (31-69%) had affection of the entire plexus, 18% (7-36%) of the upper trunk only, and 4% (1-18%) of the lower trunk. In 28% (14-48%), assessment of a definite level was not possible. In most, symptoms began during or immediately after RT, thus being without significant latency. Numbness or paresthesias (71%, 52-86%) and pain (43%, 25-62%) were the most prominent symptoms, while the most prominent objective signs were decreased or absent muscle stretch reflexes (93%, 77-99%) closely followed by sensory loss (82%, 64-93%) and weakness (71%, 52-86%). Neurophysiological investigations were carried out in 46 patients (58%). The most frequent abnormalities in patients with RBP were signs of chronic partial denervation with increased mean duration of individual motor unit potentials, and decreased amplitude of compound muscle and sensory action potentials. Nerve conduction velocities were normal. (author)

  16. Diagnostic dilemmas in foot and ankle injuries

    Keene, J.S.; Lange, R.H.

    1986-07-11

    Differential diagnosis of foot and ankle injuries should include (1) stress fractures of the great toe sesamoids, the shaft of the fifth metatarsal, and the tarsal navicular bone; (2) transchondral talar-dome fractures; (3) fractures of the os trigonum; and (4) dislocating peroneal tendons. Diagnosis of these injuries is challenging because the initial roentgenograms often are normal, and special clinical tests and ancillary studies are required.

  17. Osteoarthritis after osteosynthesis of ankle injuries

    98 patients were clinically and radiographically examined 2 to 9 years following the osteosynthesis of ankle fractures. The rate of secondary osteoarthritis was 70% including 40% of minor, 17% of medium and 13% of serious changes. Depending on the injured structures the frequency of posttraumatic osteoarthritis varies. Medium and serious radiology changes cause obvious dysfunction in 56% and 62% respectively. Joints free of Osteoarthritis one year after the injury will not develop secondary osteoarthritis later. (orig.)

  20. The management of soft tissue ankle injuries.

    Crean, D.

    1981-01-01

    The anatomy of the ankle, and the types of sporting injuries that occur in this joint, are described. Traditional treatment of soft tissue injuries involves immobilisation, and the value of this is questioned. An alternative treatment strategy is described, and involves immobilisation and compression for twenty-four hours, followed by rapid mobilisation using a balance board. This alternative strategy can bring about full functional mobility in 94% of patients within 14 days.

  1. Evaluation of brachial plexus with MR echo planar imaging: initial experience

    Objective: To determine the optimal sequences and scan parameters of Brachial Plexus MRI. Methods: Eighteen volunteers were underwent conventional MRI and echo planar imaging scanning. The images acquired were compared with the standard anatomical pictures. Results: Ventral rami, ganglion, trunks, cords and some peripheral nerves of brachial plexus were demonstrated very well by echo planar imaging with the post-processing techniques such as MIP, thin slice MIP and MPR. In 18/18 cases the postganglions on both sides and 17/18 cases the preganglions of brachial plexus on both sides could be visualized in EPI pre-processed and post-processed images. Conclusion: Echo planar imaging is an effective technique of accurately displaying brachial plexus and adjacent structures. It has potential value in the diagnosis and treatment of brachial plexus diseases. It is also a potential technique to demonstrate other peripheral nerves accurately. (authors)

  2. MR imaging of the ankle: Normal variants

    Thirty asymptomatic ankles were studied with high-resolution surface coil MR imaging. The thirty ankles were reviewed for identification or normal structures. The MR appearance of the deltoid and posterior to talo-fibular ligaments, peroneous brevis and longus tendons, and posterior aspect of the tibial-talar joint demonstrated several normal variants not previously described. These should not be misinterpreted as pathologic processes. The specific findings included (1) cortical irregularity of the posterior tibial-talar joint in 27 of 30 cases which should not be mistaken for osteonecrois; (2) normal posterior talo-fibular ligament with irregular and frayed inhomogeneity, which represents a normal variant in seven of ten cases; and (3) fluid in the shared peroneal tendons sheath which may be confused for a longitudinal tendon tear in three of 30 cases. Ankle imaging with the use of MR is still a relatively new procedure. Further investigation is needed to better define normal anatomy as well as normal variants. The authors described several structures that normally present with variable MR imaging appearances. This is clinically significant in order to maintain a high sensitivity and specificity in MR imaging interpretation

  3. Forces predicted at the ankle during running.

    Burdett, R G

    1982-01-01

    A biomechanical model of the ankle joint was developed and was used to predict the forces at the ankle during the stance phase of running. Measurements from five cadavers were averaged to obtain insertion points and directions of pull of equivalent tendons with respect to the assumed center of the ankle joint. A minimum joint force solution was obtained by assuming that only two equivalent muscle groups could exert force at one time. Three subjects ran at 4.47 m/s across a force platform that recorded the external forces and moments acting on the foot. Cinematography was used to measure the foot and leg positions during stance. Peak resultant joint forces ranging from 9.0 to 13.3 times body weight and peak Achilles tendon forces ranging from 5.3 to 10.0 times body weight were predicted. Small variations in some cases resulted in large differences in predicted forces. The highest tendon forces predicted exceeded those reported to cause damage to cadaver tendons in other studies.

  4. Kinesthesia Is Not Affected by Functional Ankle Instability Status.

    Hubbard, Tricia J; Kaminski, Thomas W

    2002-12-01

    OBJECTIVE: To determine whether subjects with functional ankle instability suffered kinesthetic deficits in the injured ankle compared with the healthy ankle and to examine the effect of prophylactic ankle bracing on kinesthesia in uninjured and functionally unstable ankles. DESIGN AND SETTING: We tested subjects over 4 consecutive days in a climate-controlled athletic training/sports medicine laboratory setting. A single-group time-series design enabled all subjects to serve as their own controls. A different bracing condition was tested on each of those occasions. SUBJECTS: Sixteen subjects (8 men, 8 women; age = 21.6 +/- 1.7 years; mass = 73.5 +/- 15.0 kg; height = 172.9 +/- 8.8 cm) with unilateral functional ankle instability participated in this study. MEASUREMENTS: Kinesthetic threshold-to-detection of passive motion (TTDPM) measurements were obtained during passive inversion and eversion movements (0.5 degrees.s(-1)) under 4 different bracing or taping conditions (unbraced, Swede-O Ankle Lok, Aircast Air-Stirrup, and tape). RESULTS: We analyzed the data using a 3-factor analysis of variance with repeated measures on the ankle and motion factors. Threshold-to-detection of passive motion scores in the unbraced condition were significantly better than the TTDPM scores in any of the other 3 test conditions. No significant differences were seen in TTDPM scores between the 2 ankles under any of the 4 conditions. CONCLUSIONS: Threshold-to-detection of passive motion scores did not differ in uninjured ankles and those with functional instability; however, bracing with either the Ankle Lok or Air-Stirrup decreased the ability to detect passive motion when compared with the no-tape (unbraced) condition. Further research is needed to determine the exact contributions of taping and bracing on ankle joint kinesthesia. PMID:12937571

    Background Lateral ankle sprain (LAS) has often been considered an injury leading to localized joint impairments affecting the musculoskeletal system. Persistent chronic ankle instability and bilateral alterations in motor control after a first ankle sprain episode suggest that the origin of relapses might be a maladaptive reorganization of central motor commands. The objectives of this study were (1) to compare the quality of motor control through motor strategy variables of two groups (with...

    Ankle inversion ligamentous sprain is one of the most common sports injuries. The most direct way is to investigate real injury incidents, but it is unethical and impossible to replicate on test participants. Simulators including tilt platforms, trapdoors, and fulcrum devices were designed to mimic ankle inversion movements in laboratories. Inversion angle was the only element considered in early designs; however, an ankle sprain is composed of inversion and plantarflexion in clinical observa...

  11. Understanding acute ankle ligamentous sprain injury in sports

    Fong Daniel TP; Chan Yue-Yan; Mok Kam-Ming; Yung Patrick SH; Chan Kai-Ming

    2009-01-01

    Abstract This paper summarizes the current understanding on acute ankle sprain injury, which is the most common acute sport trauma, accounting for about 14% of all sport-related injuries. Among, 80% are ligamentous sprains caused by explosive inversion or supination. The injury motion often happens at the subtalar joint and tears the anterior talofibular ligament (ATFL) which possesses the lowest ultimate load among the lateral ligaments at the ankle. For extrinsic risk factors to ankle sprai...

  16. Limiting the use of routine radiography for acute ankle injuries.

    Cockshott, W P; Jenkin, J. K.; Pui, M.

    1983-01-01

    In the diagnosis of ankle injuries routine radiography is often productive. An international survey of the average number of radiographs made of injured ankles suggested that two projections are adequate to detect fractures. This was confirmed in a prospective study of 242 patients coming to a hospital emergency department with recent ankle injuries. All the fractures could be identified on an anteroposterior or a lateral projection, although some were more obvious on an oblique view. As well...

    2010-01-01

    Foot and ankle injuries are extremely common among athletes and other physically active individuals. Rehabilitation programs that emphasize the use of therapeutic exercise to restore joint range of motion, muscle strength, neuromuscular coordination, and gait mechanics have been shown to have clinical success for patients suffering various foot and ankle pathologies. Rehabilitation programs are discussed for ankle sprains, plantar fasciitis, Achilles tendonitis, and turf toe.

  18. Differences in Men's and Women's Mean Ankle Ligamentous Laxity

    Wilkerson, Ricky D; Mason, Melanie A

    2000-01-01

    The incidence of ligamentous ankle injuries is known to be one of the most common athletic injuries that exists. Recently, there has been a great deal of interest regarding the increased risk of female ligamentous injury, such as the anterior cruciate ligament, lateral ankle sprains and others. The purpose of this study is to evaluate whether or not normal lateral ankle ligamentous laxity is similar in male and female athletes. This study selects 22 male and 27 female college athletes who hav...

  3. Postirradiation lesions of the brachial plexus. Results of surgical treatment

    In a series of 103 cases of postirradiation lesions of the brachial plexus operated on between 1978 and 1986--of which 60 patients have been reviewed with a follow up from 2 to 9 years--the surgical results are analyzed according to an anatomic classification, a clinical classification, and the surgical procedures. We conclude that the radiation plexitis should be treated surgically and at the earliest possible time after the onset of paresthesias. Also, the surgical procedure which gives the best results is neurolysis with pedicled omentoplasty

  4. Boston Children's Hospital approach to brachial plexus birth palsy.

    Vuillermin, Carley; Bauer, Andrea S

    2016-07-01

    The treatment of infants with brachial plexus birth palsy (BPBP) continues to be a focus at Boston Children's Hospital. Over the last 15 years, there have been many developments in the treatment of infants with BPBP. Some of the greatest changes have emerged through technical advances such as the advent of distal nerve transfers to allow targeted reinnervation as well as through research to understand the pathoanatomical changes that lead to glenohumeral dysplasia and how this dysplasia can be remodeled. This review will discuss our current practice of evaluation of the infant with BPBP, techniques for microsurgical reconstruction, and prevention and treatment of secondary glenohumeral dysplasia.

  5. Comparison of penile brachial index and penile arteriography

    Thirty patients complaining of erectile dysfunction were evaluated by measurement of the penile brachial index and arteriography. The PBIs were measured in five healthy controls. Half of the patients were studied in a vascular laboratory and the other half in a radiology-urology erectile dysfunction clinic. A poor correlation was found between PBI and arteriographic findings. No statistical difference was observed between the correlation coefficients for the two laboratory sites. Factors responsible for accurate and inaccurate assessments are discussed, and the process by which PBI measurements are obtained and their relationship to the physiology of erections is explained

    2012-02-01

    Full Text Available Introduction: Supraclavicular brachial plexus block provides safe, effective, low cost anaesthesia with good postoperative analgesia. This study was conducted to compare the postoperative analgesic efficacy and safety of dexmedetomidine for brachial plexus blockade along with bupivacaine. Methodology: This prospective double blind study was conducted on 70 patients of age 18 to 60 years posted for various upper limb surgeries and randomly allocated into two equal groups of 35 each. Control group-C received injection bupivacaine (0.25% 38 milliliter plus 2 milliliter normal saline, dexmedetomidine group-D received injection bupivacaine (0.25% 38 milliliter plus dexmedetomidine 30 microgram (2 milliliter. Assessment of motor and sensory blockade, pulse, systolic blood pressure, respiration and side effects were noted every 5 minutes for first 30 minute and every 10 minute till end of surgery. Duration of analgesia and incidence of various complications following the procedure were observed. Results: It was observed that in control group onset of motor and sensory blockade was faster. Where as, dexmedetomidine group have better hemodynamic stability and greater postoperative analgesia. Only two cases of bradycardia and two cases of hypotension were noticed in dexmedetomidine group-D. [National J of Med Res 2012; 2(1.000: 67-69

    2012-03-01

    Full Text Available Objective: Peripheral nerve blocks are usually used either alone or along with general anesthesia for postoperative analgesia. We also aimed to present the results and experiences.Materials and methods: This retrospective study was conducted to scan the files of patients who underwent orthopedic upper extremity surgery with peripheral nerve block between September 2009 and October 2010. After ethics committee approval was obtained, 114 patients who were ASA physical status I-III, aged 18-70, performed upper extremity surgery in the Orthopedics and Traumatology Clinic were included to study. Patients’ demographic data, clinical diagnoses, premedication status, peripheral block type, local anesthetic dose, stimuplex needle types, hemodynamic parameters at the during surgery, the first postoperative analgesic requirements, complications and patient satisfaction were recorded.Results: Demographic data were similar to each other. Brachial plexus block was commonly performed for the forearm surgery. Infraclavicular block was performed the most frequently to patients. As the classical methods in the supine position were preferred in 98.2% of patients, Stimuplex A needle (B. Braun, Melsungen AG, Germany have been used for blockage in 80.7% of patients. Also, in 54.4% of patients, 30 ml of local anesthetic solution composed of bupivacaine + prilocaine was used for blockade. Blocks applied to patients had provided adequate anesthesia.Conclusion: Since the brachial plexus blockade guided peripheral nerve stimulator for upper extremity surgery provide adequate depth of anesthesia and analgesia, it may be a good alternative to general anesthesia because of unwanted side effects

  11. Kinematics of ankle taping after a training session.

    Meana, M; Alegre, L M; Elvira, J L L; Aguado, X

    2008-01-01

    This study aimed to test the effectiveness of ankle taping on the limitation of forced supination during a change of direction, as well as the losses of effectiveness after a 30-minute training session. Fifteen young men with no ankle injury volunteered for the study. The static and dynamic ranges of movement (ROM) were measured before and after a training session. The dynamic measurements were recorded using high-speed 3D photogrammetry. The differences between static and dynamic measures of ankle supination and plantar flexion were significant. The losses of effectiveness during supination and ankle plantar flexion restriction were 42.3 % and 47.6 %, respectively. Ankle taping was effective in restricting the maximal static ROMs before a training session, but the effectiveness decreased after 30 min of training. The present study shows the necessity of performing dynamic ROM analysis of sports techniques involved in the ankle sprain mechanism in order to determine the degree of tape restriction after a training session, because there were differences between static and dynamic ankle ROMs. The lack of effects on the restriction of the dynamic plantar flexion would bring into question the necessity of ankle taping in subjects without previous injuries.

  12. Relationship between stress ankle radiographs and injured ligaments on MRI

    This study was performed to investigate the relationship between the injured lateral ankle ligaments on MRI and stress ankle radiographs. Two hundred and twenty-nine consecutive patients (mean age 35.5 years, SD 14.6 years; 136 males and 93 females) that underwent ankle stress radiographs and MRI for lateral ankle instability were included. Tibiotalar tilt angle and anterior translation of talus were measured on stress ankle radiographs. Degree of lateral ligaments (anterior talofibular, calcaneofibular, and posterior talofibular) and deltoid ligament injuries were evaluated and scored as intact (0), partial injury (1), and complete injury (2) on MR images. Effusion of ankle joint was also recorded. The effects of gender, age, injuries of ligaments, and ankle joint effusion on stress radiographs were statistically analyzed. Gender (p = 0.010), age (p = 0.020), and anterior talofibular ligament (ATFL) injury (p < 0.001) were the factors significantly affecting tibiotalar tilt angle. Posterior talofibular ligament (PTFL) injury (p = 0.014) was found to be the only significant factor affecting the anterior translation on the anterior drawer radiographs. ATFL injury and PTFL injury on MRI significantly affected tibiotalar tilt angle and anterior drawer on stress radiographs. Other factors, such as age and gender, need to be considered in evaluating radiographic lateral ankle instability. (orig.)

  13. Magnetic resonance imaging findings in anterolateral impingement of the ankle

    Objective. To demonstrate the MR imaging findings of anterolateral impingement (ALI) of the ankle.Design and patients. Nine patients with a history of ankle inversion injury and chronic lateral ankle pain were imaged with MR imaging, and the findings correlated with the results of arthroscopy. Three additional patients with clinically suspected ALI of the ankle were also included. Ankle MR imaging studies from 20 control patients in whom ALI was not suspected clinically were examined for similar findings to the patient group.Results. MR imaging findings in the patients with ALI included a soft tissue signal mass in the anterolateral gutter of the ankle in 12 of 12 (100%) cases, corresponding to the synovial hypertrophy and soft tissue mass found at arthroscopy in the nine patients who underwent arthroscopy. Disruption, attenuation, or marked thickening of the anterior talofibular ligament was seen in all cases. Additional findings included signs of synovial hypertrophy elsewhere in the tibiotalar joint in seven of 12 patients (58%) and bony and cartilaginous injuries to the tibiotalar joint in five of 12 (42%). None of the control patients demonstrated MR imaging evidence of a soft tissue mass in the anterolateral gutter.Conclusions. ALI of the ankle is a common cause for chronic lateral ankle pain. It has been well described in the orthopedic literature but its imaging findings have not been clearly elucidated. The MR imaging findings, along with the appropriate clinical history, can be used to direct arthroscopic examination and subsequent debridement. (orig.)

  1. FEATURES OF THE X-RAY ANATOMICAL CONDITIONS OF THE FOOT AND ANKLE IN CHILDREN WITH FIBULAR APLASIA

    Dmitry Stepanovich Buklaev

    2013-03-01

    Full Text Available The article contains the results of the analysis of radiographs of the foot and ankle in 84 children with malformations of the fibula. We found that infants’ relation to the ankle joint is often normal, as in the sagittal and frontal planes. With increasing age the number of posterior subluxation increases as well as anteriorly, laterally. Also dislocations of the foot were presented. The most significant relationships were violations of the subtalar joint. There were pronation, supinatsion, positions of calcaneus bone and its lateroposition, which was the most frequent cause of valgus deformity. Also we found a violation of the form of the talus such as a flattening of the block, smoothing of the neck. In rare cases of the varus deformity of the foot abnormalities of the tarsal bones were observed.

  2. Understanding acute ankle ligamentous sprain injury in sports

    Fong Daniel TP

    2009-07-01

    Full Text Available Abstract This paper summarizes the current understanding on acute ankle sprain injury, which is the most common acute sport trauma, accounting for about 14% of all sport-related injuries. Among, 80% are ligamentous sprains caused by explosive inversion or supination. The injury motion often happens at the subtalar joint and tears the anterior talofibular ligament (ATFL which possesses the lowest ultimate load among the lateral ligaments at the ankle. For extrinsic risk factors to ankle sprain injury, prescribing orthosis decreases the risk while increased exercise intensity in soccer raises the risk. For intrinsic factors, a foot size with increased width, an increased ankle eversion to inversion strength, plantarflexion strength and ratio between dorsiflexion and plantarflexion strength, and limb dominance could increase the ankle sprain injury risk. Players with a previous sprain history, players wearing shoes with air cells, players who do not stretch before exercising, players with inferior single leg balance, and overweight players are 4.9, 4.3, 2.6, 2.4 and 3.9 times more likely to sustain an ankle sprain injury. The aetiology of most ankle sprain injuries is incorrect foot positioning at landing – a medially-deviated vertical ground reaction force causes an explosive supination or inversion moment at the subtalar joint in a short time (about 50 ms. Another aetiology is the delayed reaction time of the peroneal muscles at the lateral aspect of the ankle (60–90 ms. The failure supination or inversion torque is about 41–45 Nm to cause ligamentous rupture in simulated spraining tests on cadaver. A previous case report revealed that the ankle joint reached 48 degrees inversion and 10 degrees internal rotation during an accidental grade I ankle ligamentous sprain injury during a dynamic cutting trial in laboratory. Diagnosis techniques and grading systems vary, but the management of ankle ligamentous sprain injury is mainly conservative

  3. Clinical experiences with three different designs of ankle prostheses.

    Rippstein, Pascal F

    2002-12-01

    Until 1995, fusion was in our institution the only rational surgical option for a severe ankle arthrosis. Consistent reports about good mid- and long-term results with ankle replacement allowed us to change our minds. Ankle replacement became the gold standard and fusion was then almost totally banished. Because ankle arthrosis can be morphologically different from one patient to another, we soon believed that one single type of ankle prosthesis would not be the universal optimal solution for all patients. We therefore divided the ankle arthrosis into three groups. Each group shows the best solution from each of the ankle prostheses with which we had gained experience (Agility, STAR, and BP). The Agility prosthesis, which was indicated for ankles with extremely damaged geometry, did not restore sufficiently the ankle motion. Preoperatively stiff ankles remained stiff postoperatively. Additionally, significant residual pain was more likely to occur in those patients. These cases did not show significant advantages compared with ankle fusion, especially from a functional point of view. Fusion for these stiff ankles is therefore today our first treatment of choice. In our experience, the malleolar joints do not have to be replaced. Even a severe arthrosis at this level does not produce significant pain, provided that osteophytes have been removed and joint height has been restored by the implanted prosthesis. It is our strong belief that these malleolar joints are also less sensitive to pain, similar to the femoropatellar joint. For these reasons, a replacement of the malleolar joints and the resurfacing of the talar sides is not necessary. Leaving the talar sides untouched requires less bone resection and makes the implantation of the talar component easier. Although we obtained good results with the STAR prosthesis, we progressively abandoned it because of these reasons, and we preferred the BP prosthesis. The BP prosthesis works on the same biomechanic principle as

  4. Robotic Ankle for Omnidirectional Rock Anchors

    Parness, Aaron; Frost, Matthew; Thatte, Nitish

    2013-01-01

    Future robotic exploration of near-Earth asteroids and the vertical and inverted rock walls of lava caves and cliff faces on Mars and other planetary bodies would require a method of gripping their rocky surfaces to allow mobility without gravitational assistance. In order to successfully navigate this terrain and drill for samples, the grippers must be able to produce anchoring forces in excess of 100 N. Additionally, the grippers must be able to support the inertial forces of a moving robot, as well gravitational forces for demonstrations on Earth. One possible solution would be to use microspine arrays to anchor to rock surfaces and provide the necessary load-bearing abilities for robotic exploration of asteroids. Microspine arrays comprise dozens of small steel hooks supported on individual suspensions. When these arrays are dragged along a rock surface, the steel hooks engage with asperities and holes on the surface. The suspensions allow for individual hooks to engage with asperities while the remaining hooks continue to drag along the surface. This ensures that the maximum possible number of hooks engage with the surface, thereby increasing the load-bearing abilities of the gripper. Using the microspine array grippers described above as the end-effectors of a robot would allow it to traverse terrain previously unreachable by traditional wheeled robots. Furthermore, microspine-gripping robots that can perch on cliffs or rocky walls could enable a new class of persistent surveillance devices for military applications. In order to interface these microspine grippers with a legged robot, an ankle is needed that can robotically actuate the gripper, as well as allow it to conform to the large-scale irregularities in the rock. The anchor serves three main purposes: deploy and release the anchor, conform to roughness or misalignment with the surface, and cancel out any moments about the anchor that could cause unintentional detachment. The ankle design contains a

    Myrick, Karen M

    2014-01-01

    Ankle sprains are a common occurrence and are frequently either undertreated or overtreated. With the incidence estimated at more than 3 million a year and at a rate of 2.15/1,000 in the United States alone, this is an orthopaedic injury that providers should be acutely aware of and successfully able to evaluate and treat. This clinical feature will provide a thorough review of the mechanism of injury, the history and physical examination, and the classification and management of these injuries. Clinical red flags are discussed. PMID:25233201

  6. Dose Constraints to Prevent Radiation-Induced Brachial Plexopathy in Patients Treated for Lung Cancer

    Purpose: As the recommended radiation dose for non-small-cell lung cancer (NSCLC) increases, meeting dose constraints for critical structures like the brachial plexus becomes increasingly challenging, particularly for tumors in the superior sulcus. In this retrospective analysis, we compared dose-volume histogram information with the incidence of plexopathy to establish the maximum dose tolerated by the brachial plexus. Methods and Materials: We identified 90 patients with NSCLC treated with definitive chemoradiation from March 2007 through September 2010, who had received >55 Gy to the brachial plexus. We used a multiatlas segmentation method combined with deformable image registration to delineate the brachial plexus on the original planning CT scans and scored plexopathy according to Common Terminology Criteria for Adverse Events version 4.03. Results: Median radiation dose to the brachial plexus was 70 Gy (range, 56–87.5 Gy; 1.5–2.5 Gy/fraction). At a median follow-up time of 14.0 months, 14 patients (16%) had brachial plexopathy (8 patients [9%] had Grade 1, and 6 patients [7%] had Grade ≥2); median time to symptom onset was 6.5 months (range, 1.4–37.4 months). On multivariate analysis, receipt of a median brachial plexus dose of >69 Gy (odds ratio [OR] 10.091; 95% confidence interval [CI], 1.512–67.331; p = 0.005), a maximum dose of >75 Gy to 2 cm3 of the brachial plexus (OR, 4.909; 95% CI, 0.966–24.952; p = 0.038), and the presence of plexopathy before irradiation (OR, 4.722; 95% CI, 1.267–17.606; p = 0.021) were independent predictors of brachial plexopathy. Conclusions: For lung cancers near the apical region, brachial plexopathy is a major concern for high-dose radiation therapy. We developed a computer-assisted image segmentation method that allows us to rapidly and consistently contour the brachial plexus and establish the dose limits to minimize the risk of brachial plexopathy. Our results could be used as a guideline in future

    Purpose: As the recommended radiation dose for non-small-cell lung cancer (NSCLC) increases, meeting dose constraints for critical structures like the brachial plexus becomes increasingly challenging, particularly for tumors in the superior sulcus. In this retrospective analysis, we compared dose-volume histogram information with the incidence of plexopathy to establish the maximum dose tolerated by the brachial plexus. Methods and Materials: We identified 90 patients with NSCLC treated with definitive chemoradiation from March 2007 through September 2010, who had received >55 Gy to the brachial plexus. We used a multiatlas segmentation method combined with deformable image registration to delineate the brachial plexus on the original planning CT scans and scored plexopathy according to Common Terminology Criteria for Adverse Events version 4.03. Results: Median radiation dose to the brachial plexus was 70 Gy (range, 56-87.5 Gy; 1.5-2.5 Gy/fraction). At a median follow-up time of 14.0 months, 14 patients (16%) had brachial plexopathy (8 patients [9%] had Grade 1, and 6 patients [7%] had Grade {>=}2); median time to symptom onset was 6.5 months (range, 1.4-37.4 months). On multivariate analysis, receipt of a median brachial plexus dose of >69 Gy (odds ratio [OR] 10.091; 95% confidence interval [CI], 1.512-67.331; p = 0.005), a maximum dose of >75 Gy to 2 cm{sup 3} of the brachial plexus (OR, 4.909; 95% CI, 0.966-24.952; p = 0.038), and the presence of plexopathy before irradiation (OR, 4.722; 95% CI, 1.267-17.606; p = 0.021) were independent predictors of brachial plexopathy. Conclusions: For lung cancers near the apical region, brachial plexopathy is a major concern for high-dose radiation therapy. We developed a computer-assisted image segmentation method that allows us to rapidly and consistently contour the brachial plexus and establish the dose limits to minimize the risk of brachial plexopathy. Our results could be used as a guideline in future prospective

    Primary brachial plexus tumors are rare, usually benign, and in general have a good prognosis after surgical excision. We present a case of a schwannoma in which sonography enabled the correct diagnosis of a probably benign brachial plexus tumor. Key to the diagnosis was the demonstration of a smooth-bordered, longish, and well-defined nodule along a brachial plexus nerve root. Cross-sectional imaging modalities that provide a high degree of soft tissue contrast and spatial resolution, such as sonography and MR imaging, were suitable methods to establish the correct preoperative diagnosis. Findings at CT, sonography, MR imaging, and surgery are discussed. (orig.)

  11. Distinction between neoplastic and radiation-induced brachial plexopathy, with emphasis on the role of EMG

    The results of clinical, radiologic, and electrophysiologic studies are retrospectively reviewed for 55 patients with neoplastic and 35 patients with radiation-induced brachial plexopathy. The presence or absence of pain as the presenting symptom, temporal profile of the illness, presence of a discrete mass on CT of the plexus, and presence of myokymic discharges on EMG contributed significantly to the prediction of the underlying cause of the brachial plexopathy. The distribution of weakness and the results of nerve conduction studies were of no help in distinguishing neoplastic from radiation-induced brachial plexopathy

  12. MRI of injuries of the lateral ankle ligaments

    The most frequent sport injury of the ankle is located in the lateral ankle ligaments. The diagnosis of lateral collateral ankle ligament trauma is based on patient history, clinical examination, and stress radiography, allowing a fair diagnosis for the daily routine. For the direct visualization and precise diagnosis of the lateral ankle ligaments MRI provides the best answer. MRI is used with controlled positioning of the foot, correct angulation of sequenzes, and distinct analysis of MR findings. Sinus tarsi ligaments and ligaments of the distal syndesmosis should be included to the report. In selected patients MRI allows the best evaluation of the extent of the lateral ankle ligaments. MRI is the method of choice for combined osteochondral injuries and soft tissue lesions too. (orig.)

    Syndesmosis sprains in the National Football League (NFL) can be a persistent source of disability, especially compared with lateral ankle injuries. This study evaluated syndesmosis and lateral ankle sprains in NFL players to allow for better identification and management of these injuries. Syndesmosis and lateral ankle sprains from a single NFL team database were reviewed over a 15-year period, and 32 NFL team physicians completed a questionnaire detailing their management approach. A comparative analysis was performed analyzing several variables, including diagnosis, treatment methods, and time lost from sports participation. Thirty-six syndesmosis and 53 lateral ankle sprains occurred in the cohort of NFL players. The injury mechanism typically resulted from direct impact in the syndesmosis and torsion in the lateral ankle sprain group (P=.034). All players were managed nonoperatively. The mean time lost from participation was 15.4 days in the syndesmosis and 6.5 days in the lateral ankle sprain groups (P⩽.001). National Football League team physicians varied treatment for syndesmosis sprains depending on the category of diastasis but recommended nonoperative management for lateral ankle sprains. Syndesmosis sprains in the NFL can be a source of significant disability compared with lateral ankle sprains. Successful return to play with nonoperative management is frequently achieved for syndesmosis and lateral ankle sprains depending on injury severity. With modern treatment algorithms for syndesmosis sprains, more aggressive nonoperative treatment is advocated. Although the current study shows that syndesmosis injuries require longer rehabilitation periods when compared with lateral ankle sprains, the time lost from participation may not be as prolonged as previously reported.

    This study was carried out to evaluate the long-term effect on the donor side of the foot and ankle following vascularized fibular graft resection in children. Eight patients underwent resection of the fibula for the purpose of a vascularized fibular graft by a surgical team who practiced leaving at least 6 cm residual distal fibula. The age of these children at the time of surgery was between 3 and 12 years. They were reviewed between 3 and 12 years after surgery. Two patients who underwent resection of the middle shaft of the fibula at 3 and 5 years of age developed abnormal growth of the distal tibia, leading to ankle valgus. They were treated with growth modulation of the distal tibial physis and supramalleolar osteotomy with tibiofibular synostosis. Another patient who underwent the entire proximal fibula resection at the age of 6 years had developed hindfoot valgus because of weakness of the tibialis posterior muscle. He required talonavicular fusion and flexor hallucis to tibialis posterior muscle transfer. Patients operated at the age of older than 8 years neither had ankle nor hindfoot deformity. We concluded that resection of the middle shaft of the fibula for the purpose of a vascularized fibula graft, leaving a 6 cm distal fibular stump in children younger than 6 years old, may give rise to abnormal growth of the distal tibial physis, leading to valgus ankle. The entire proximal fibular resection for the similar purpose in a 6-year-old child may give rise to weakness of tibialis posterior and hindfoot valgus. PMID:26049965

  17. Fracture line index of fibular stalk and the ankle joint bone in the classification of the ankle joint trauma

    Objective: To evaluate the fracture line index of fibular stalk and the ankle joint bone in the classification of the ankle joint trauma. Methods: Measure fracture line index of fibular stalk and the ankle joint in 217 adult cases of fracture and dislocation of ankle joint. And the cases were classified by the results of the measurement. Results: Measurement was unavailable in 9 cases of tearing fracture. In 31 cases, the lesions could not be particularly classified. And in the rest 176 cases the trauma were precisely classified. The over all successful rate was 81.6%. Conclusion: Fracture line index of fibular stalk and the ankle joint bone are valuable in classification of the trauma of the angle joint. While the specificity of this method is low in differentiating the adducting and abducting fracture of the medial angle, in which a combined investigation is recommended

  18. The foot and ankle of Australopithecus sediba.

    A well-preserved and articulated partial foot and ankle of Australopithecus sediba, including an associated complete adult distal tibia, talus, and calcaneus, have been discovered at the Malapa site, South Africa, and reported in direct association with the female paratype Malapa Hominin 2. These fossils reveal a mosaic of primitive and derived features that are distinct from those seen in other hominins. The ankle (talocrural) joint is mostly humanlike in form and inferred function, and there is some evidence for a humanlike arch and Achilles tendon. However, Au. sediba is apelike in possessing a more gracile calcaneal body and a more robust medial malleolus than expected. These observations suggest, if present models of foot function are correct, that Au. sediba may have practiced a unique form of bipedalism and some degree of arboreality. Given the combination of features in the Au. sediba foot, as well as comparisons between Au. sediba and older hominins, homoplasy is implied in the acquisition of bipedal adaptations in the hominin foot.

  19. Interscalenic approach to the cervico-brachial plexus.

    Evenepoel, M C; Blomme, A

    The concept of a closed peri-neurovascular space surrounding the cervicobrachial plexus, introduced by A. Winnie, allows the blockade of the cervical and brachial plexuses by means of a single puncture technique. The single puncture has positive advantages: 1. The rapidity of the blockade; 2. The simplicity of the blockade; 3. Comfort for the patient. The landmarks are easy to make. As with epidural blockade, the injection level and the volume of local anesthetic determine the quality and extent of the block. The traditional indication is surgery of the shoulder and of the supraclavicular area. A new indication seems to be the implantation of a cardiac pacemaker. Complications often quoted in literature are Horner syndrome-a minor complication-and blockade of the ascending branches of the recurrent laryngeal nerve and of the phrenic nerve. The risk of a pneumothorax is almost nil. PMID:7324853

    Full Text Available Adult post traumatic Brachial plexus injury is unfortunately a rather common injury in young adults. In India the most common scenario is of a young man injured in a motorcycle accident. Exact incidence figures are not available but of the injuries presenting to us about 90% invole the above combination This article reviews peer-reviewed publications including clinical papers, review articles and Meta analysis of the subject. In addition, the authors′ experience of several hundred cases over the last 15 years has been added and has influenced the ultimate text. Results have been discussed and analysed to get an idea of factors influencing final recovery. It appears that time from injury and number of roots involved are most crucial.
