Validity and reliability of the Greek version of the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form.

BACKGROUND: The aim of our study is to prove the validity and reliability of the Greek translated version of the self-report section of the American Shoulder and Elbow Surgeons (ASES) questionnaire. METHODS: A total of 108 patients with various shoulder disorders were evaluated at two different orthopedic centers. All patients answered the Greek ASES questionnaire as well as the previously validated Greek version of the Disability Arm Shoulder and Hand score. Three days after the first evaluation, a subgroup of 40 individuals was randomly selected to complete again the Greek ASES text to prove its reliability, after the test-retest procedure. Reliability was tested with Cronbach's alpha, stability by calculating the intraclass correlation coefficient and by Blant Altman plot and structural validity with the confirmatory factor analysis. RESULTS: The internal consistency of the ASES functional score and the ASES total score was 0.925 and 0.750 respectively. The intraclass correlation coefficient between initial assessment and reassessment of the ASES functional and total score was 0.951 and 0.938 (P < .001), respectively. The correlation coefficients correlation between the ASES functional and total scores with DASH total score were -0.881 and -0.759 (P < .001), respectively. CONCLUSIONS: The Greek ASES version proved to be equivalent to the English original version in evaluating different shoulder disorders in the Greek population.

Rupture of the flexor digitorum superficialis at the musculotendinous junction due to a forearm fracture: a case report.

We present a case of a closed distal-third forearm fracture, in which the flexor digitorum superficialis was found ruptured at its musculotendinous junction. We diagnosed the ruptured tendon during the exploration of the ulnar nerve for observed preoperative palsy. Although there are numerous reports about avulsions at the bony insertions, there are very few about avulsion at the musculotendinous junction in the literature. This consideration leads to the conclusion that this kind of rupture may be more frequent than recognized.

Lipomatosis of the sciatic nerve: report of a case and review of the literature.

We report a case of lipomatosis of the sciatic nerve, also known as lipofibromatous hamartoma. A male, 26-year-old, presented with gait impairment, leg pain, and foot drop compatible with sciatic nerve's compression. The preoperative magnetic resonance imaging (MRI) revealed diffuse thickening of the proximal third of the sciatic nerve with adipose tissue interspersed among the nerve fascicles. Internal neurolysis was performed with microsurgical techniques under high magnification. The patient was followed up for a period of 34 months. He significantly recovered, and there was no clinical recurrence of the tumor.
