Thus, it is speculated that such patients generally have a poor prognosis. How absent sensory nerve action potential affects surgical outcomes remains uncertain owing to a scarcity of reports and conflicting results. This retrospective study recruited one hundred and fourteen cases(88 patients with absent sensory nerve action potential and 26 patients with present sensory nerve action potential) undergoing either subcutaneous transposition or in situ decompression. The minimum follow-up was set at 2 years. Primary outcome measures of overall hand function included their McGowan grade, modified Bishop score, and Disabilities of the Arm, Shoulder, and Hand Questionnaire(DASH) score. For patients with absent sensory nerve action potential, 71 cases(80.7%) achieved at least one McGowan grade improvement, 76 hands(86.4%) got good or excellent results according to the Bishop score, and the average DASH score improved 49.5 points preoperatively to 13.1 points postoperatively. When compared with the present sensory nerve action potential group, they showed higher postoperative McGowan grades and DASH scores, but there was no statistical difference between the modified Bishop scores of the two groups. Following in situ decompression or subcutaneous transposition, great improvement in hand function was achieved for severe cubital tunnel syndrome patients with absent sensory nerve action potential. The functional outcomes after surgery for severe cubital tunnel syndrome are worse in patients with absent sensory nerve action potential than those without. This study was approved by the Ethical Committee of Huashan Hospital, Fudan University, China(approval No. 2017142).展开更多

This study was designed to investigate the causes of cubital tunnel syndrome by surgical means and to assess the clinical value of the neurophysiological diagnosis of cubital tunnel syndrome. Methods Twenty-one patients (involving a total of 22 limbs from 16 men and 5 women, aged 22 to 63, with a mean age of 49 years) with clinical symptoms and signs indicating a problem with their ulnar nerve underwent motor conduction velocity examinations at different sites along the ulnar nerve and examinations of sensory conduction velocity in the hand, before undergoing anterior transposition of the ulnar nerve.Results Electromyographic abnormalities were seen in 21 of 22 limbs [motor nerve conduction velocity (MCV) range (15.9-47.5) m/s, mean 32.7 m/s] who underwent motor conduction velocity examinations across the elbow segment of the ulnar nerve. Reduced velocity was observed in 13 of 22 limbs [MCV (15.7-59.6) m/s, mean 40.4 m/s] undergoing MCV tests in the forearms. An absent or abnormal sensory nerve action potential following stimulation was detected in the little finger of 14 of 22 limbs. The factors responsible for ulnar compression based on observations made during surgery were as follows: 15 cases involved compression by arcuate ligaments, muscle tendons, or bone hyperplasia; 2 involved fibrous adhesion; 3 involved compression by the venous plexus or a concurrent thick vein; 2 involved compression by cysts. Conclusions Factors inducing cubital tunnel syndrome include both common factors that have been reported and rare factors, involving the venous plexus, thick veins, and cysts. Tests of motor conduction velocity at different sites along the ulnar nerve should be helpful in diagnosis cubital tunnel syndrome, especially MCV tests indicating decreased velocity across the elbow segment of the ulnar nerve.展开更多

The goal of this study was to determine the effect of different elbow positions at full extension and 70° flexion on SSNCS in CubTS. Methods： In this cross-sectional study, the clinical data of seventy elbows from 59 CubTS patients between September, 2011 and December, 2014 in the Peking University First Hospital were included as CubTS group. Moreover, thirty healthy volunteers were included as the healthy group. SSNCS were conducted in all subjects at elbow fhll extension and 70° elbow flexion. Paired nonparametric test, bivariate correlation, Bland-Altman, and Chi-squared test analysis were used to compare the effectiveness of elbow full extension and 70° flexion elbow positions on SSNCS in CubTS patients. Results： Data of upper limit was calculated from healthy group, and abnormal latency was judged accordingly. CubTS group＇s latency and compound muscle action potential （CMAP） of each segment at 70° elbow flexion by SSNCS was compared with lull extension position, no statistically significant difference were found （all P 〉 0.05）. Latency and CMAP of each segment at elbow full extension and 70° flexion were correlated （all P 〈 0 elbow （P - 0.43）, and the latency （P = 0.15） and the CMAP （P = 01）, except the latency of segment of 4 cm to 6 cm above 0.06） of segment of 2 cm to 4 cm below elbow. Bivariate correlation and Bland-Altman analysis proved the correlation between elbow full extension and 70° flexion. Especially in segments across the elbow （2 cm above the elbow and 2 cm below it）, latency at elbow full extension and 70° flexion were strong direct associated（r=0.83, P〈0.01;r=0.55, P〈0.01）,andsodidtheCMAP（r 0.49, P〈0.01;r=0.72, P〈0.01）.Therewasno statistically significant difference in abnormality of each segment at full extension as measured by SSNCS compared with that at 70° flexion （P 〉 0.05, respectively）. Conclusions： There was no statistically significant difference in the diagnosis of CubTS with the elbow at full extension compared with that at 70° flexion during SSNCS. We suggest that elbow positon at full extension can also be used during SSNCS.展开更多

The purpose of this study was to investigate and clarify the etiology and associated factors for CTS and CuTS in the Japanese general population. Methods: A total of 1875 participants, who participated in health checkups conducted in rural areas in Japan in 2010, were enrolled. The prevalence of CTS and CuTS was investigated. Logistic regression models were performed to examine the relationship between CTS and CuTS and correlated factors such as occupational status, smoking and alcohol preferences, and medical characteristics. Results: The overall prevalence of CTS and CuTS was 2.0% and 2.2%, respectively. With regards to CTS, female subjects showed 7.33-times higher risk of CTS compared with male subjects. In addition, hypertension was also at high risk of CTS (5.56-times higher in borderline and 4.55-times higher in definite hypertension compared with normal blood pressure). However, there were no significant associations between CuTS and age, gender, occupation, smoking and alcohol preferences, or metabolic factors. Conclusions: CTS was associated with female gender and hypertension, whereas there was no obvious risk factor contributing to the onset of CuTS.展开更多
