    Analysis of Subcutaneous Anterior Transposition versus in-situ Decompression of Ulnar Nerve with Force Transducer in Cadaver Specimen

    AIM: To evaluate the changes in the pressure values of the ulnar nerve after in-situ decompression and anterior subcutaneous transposition of the ulnar nerve. MATERIAL and METHODS: The ulnar nerve was released in the postcondylar groove. An ultrathin (100 lm) force transducer was embedded between the posterior of the ulnar nerve and the anterior of the medial epicondyle. The elbow joint was flexed from full extension position to maximum flexion and was measured to obtain the maximum stress at 0 degrees, 45 degrees, 90 degrees, and 135 degrees of flexion. Then, the ulnar nerve was transposed anterior subcutaneously. The same measurement was applied to the two procedures. Data were compared between the two surgical techniques. RESULTS: Our study was performed on the right upper extremities of eight (seven men and one woman) fresh frozen cadavers. The mean age of the cadavers was 67.25 +/- 12.2 years. Mean values of 0 degrees, 45 degrees, 90 degrees, and 135 degrees of flexion after the ulnar nerve insitu decompression were 0.41, 0.9, 1.7, and 4.3 N, respectively. Mean values of 0 degrees, 45 degrees, 90 degrees, and 135 degrees of flexion after anterior transposition of the ulnar nerve were 0.3, 0.73, 1.63, and 2.15 N, respectively. No significant difference was noted between the two groups in terms of 0 degrees, 45 degrees, and 90 degrees of flexion values. However, there was a significant difference between the two groups in the 135 degrees of flexion measurement values. CONCLUSION: Anterior transposition is a more appropriate technique than in-situ decompression in the treatment of cubital tunnel syndrome that does not respond to conservative treatment regardless of the severity of the symptom.

    Assessment of the Quality and Reliability of the Information on Rotator Cuff Repair on YouTube
    (ELSEVIER MASSON, CORP OFF, 2020-01-01) Celik, Haluk; Polat, Omer; Ozcan, Cagri; Camur, Savas; Kilinc, Bekir Eray; Uzun, Metin
    Introduction: YouTube has become a common health information source for patients. Recent studies have determined that videos on YouTube contain misleading and inappropriate information for different medical conditions. The aim of the present study was to assess the quality and reliability of videos pertaining to rotator cuff (RC) repair surgery. Hypothesis: YouTube users prefer watching videos with high educational quality which are provided by physicians. Material and methods: A search was performed using keywords ``rotator cuff surgery{''} and ``rotator cuff repair{''} on YouTube and the first 100 videos for each keyword were analyzed. Video source, time since upload, duration, and number of views, likes, and dislikes were recorded. Video popularity was reported using the video power index (VPI) and view ratio. Video educational quality was measured using the recognized DISCERN, the Journal of the American Medical Association (JAMA) score and a novel RC-specific score (RCSS). Results: Among the 200 videos identified, 67 were included. The mean duration was 7.7 minutes and the mean number of the views was 147,430. Videos uploaded by a physician had significantly higher DISCERN, JAMA, and RCSS (p < 0.001). While the main video source was physicians (48\%), the most popular videos were uploaded by patients and commercial websites, according to the VPI and view ratios. The number of likes, view ratios, and VPI were negatively correlated with each score. There were negative correlations between duration and VPI scores, and positive correlations with DISCERN, JAMA score, and RCSS. Animated videos showed significantly lower results for all quality scores (p <0.05), while their VPI was significantly higher (p < 0.01). Discussion: Online information on RC repair surgery provided by YouTube was low quality, despite being mostly uploaded by physicians and having relatively higher quality scores. YouTube users prefer watching low quality videos which were provided by patients and commercial websites. (C) 2019 Elsevier Masson SAS. All rights reserved.
