Translation and cultural adaptation of the oxford hip score for Iranian population.

INTRODUCTION: In recent years, outcome assessment related to orthopedic surgeries has increasingly focused on patient-reported questionnaires. The Oxford Hip Score (OHS), self-administered questionnaire, is a reliable, valid, and responsive instrument for assessing hip in patients undergoing Arthroplasty. METHODS: The study involved 105 adult Persian-speaking patients admitted for primary Total Hip Arthroplasty in two hospitals in Isfahan in Iran from September 2009 until April 2011. All of them filled out their scales (Persian OHS, WOMAC, and SF12) in preoperative examination. RESULTS: Mean scores of OHS in first administrations was 42.7 ± 12.7. The Persian OHS overall score demonstrated high reproducibility (ICC,0.93, P < 0.001) and internal consistency (CA, 0.94). PersianOHS had high correlations with WOMAC total score (r = 0.86), function score (r = 0.86), and pain score (r = 0.79), the relationship between the Persian OHS and the WOMAC stiffness subscale was somewhat lower (r = 0.69). The correlation coefficient between the Persian OHS and the PCS of the SF-12 in our study was moderate (r = 0.58). Persian OHS had low correlation with MCS of the SF-12 (r = 0.40). DISCUSSION: Persian OHS had high correlations with WOMAC total score, function score, and pain score. It had moderate correlation with PCS of the SF-12 and low correlation with MCS of the SF-12. CONCLUSIONS: Our study demonstrated the trans-cultural adaptation and validation of the Persian OHS is a reliable and practicable instrument for assessment of function and pain in Iranian patients with hip osteoarthritis.

Comparison of anterior subcutaneous and submuscular transposition of ulnar nerve in treatment of cubital tunnel syndrome: A prospective randomized trial.

BACKGROUND: This study was designed to compare two methods of surgery, anterior subcutaneous transposition (ASCT) and anterior submuscular transposition (ASMT) of the ulnar nerve in treatment of cubital tunnel syndrome. MATERIALS AND METHODS: This randomized trial study was conducted from October 2008 to March 2009 in the Department of Orthopedic Surgery at University Hospital. Forty-eight patients with confirmed cubital tunnel syndrome were randomized in two groups, and each patient received one of two different surgical treatment methods, either ASCT (n = 24) or ASMT (n = 24). In the ASCT technique, the ulnar nerve was transposed and retained in the subcutaneous bed, whereas in the ASMT, the nerve was retained deep in the transected muscular complex, near the median nerve. Patient outcomes, including pain, sensation, muscle strength, and muscle atrophy were compared between groups. RESULTS: The two groups were similar in baseline characteristics. However, those treated with ASMT had a statistically significant reduction in their pain levels compared with ASCT (21 (87.5%) vs 8 (33.3%), P < 0.05). There were no statistically significant differences between the two groups relative to sensation (11 (45.8%) vs 12 (50%)), muscle strength (17 (70.8%) vs 15 (62.5%)), or muscle atrophy (15 (62.5%) vs 17 (70.8%)) (P > 0.05). CONCLUSIONS: Our results indicate that ASMT are more efficient than ASCT for managing cubital tunnel syndrome. In patients who had ASMT, there were significant reductions of pain compared with ASCT.
