Purpose To use the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement checklist to critically evaluate the change in quality of observational trial reporting in the Journal of Hand Surgery American between 2005 and 2011. Methods A cross-sectional analysis of observational studies published in Journal of Hand Surgery American was designed to sample 2 6-month periods of publication (March 2005 - August 2005 and June 2011 - November 2011). Fifty-one items were extracted from the STROBE statement for evaluation. Overall STROBE compliance rates for articles and specific checklist items were determined. Final compliance percentages from each period were compared by Student t-testing. Changes in item compliance over time were quantified. Results Overall compliance with the STROBE statement was 38% (range, 10-54%) in 2005 and 58% (range, 39%-85%) for 2011 manuscripts representing a significant improvement. Seventy-five percent or greater of articles (2005/2011) provided the explicit reporting of background (100%/97%), follow-up time (85%/94%), overall interpretation of data (100%/94%), and results of similar studies (95%/89%). Twenty-five percent or less of articles provided the study design in the abstract (10%/20%), a clear description of the study's setting (10%/23%), the handling of missing data (0%/6%), the potential directions of bias (5%/11%) and use of a power analysis (0%/17%). Eighty-six percent (44/51) of items were more frequently satisfied in 2011 articles compared to 2005 publications. Absolute increases in compliance rates of ≥40% were noted in 10 items (20%) with no worsening in compliance for an individual item over 6%. Discussion The overall quality of the reporting of observational trials in Journal of Hand Surgery American improved from 2005 to 2011. Current observational trials in hand surgery could still benefit from increased reporting of methodologic details including the use of power analyses, the handling of missing data, and consideration of potential bias.

Background: Shoulder external rotation recovery in brachial plexus birth injury is often limited. Nerve grafting to the suprascapular nerve and transfer of the spinal accessory nerve to the suprascapular nerve are commonly performed to restore shoulder external rotation, but the optimal surgical technique has not been clearly demonstrated. We investigated whether there was a difference between nerve grafting and nerve transfer in terms of shoulder external rotation recovery or secondary shoulder procedures. Methods: This is a multicenter, retrospective cohort study of 145 infants with brachial plexus birth injury who underwent reconstruction with nerve grafting to the suprascapular nerve (n = 59) or spinal accessory nerve to suprascapular nerve transfer (n = 86) with a minimum follow-up of 18 months (median, 25.7 months [interquartile range, 22.0, 31.2 months]). The primary outcome was the Active Movement Scale (AMS) score for shoulder external rotation at 18 to 36 months. The secondary outcome was secondary shoulder surgery. Two-sample Wilcoxon and t tests were used to analyze continuous variables, and the Fisher exact test was used to analyze categorical variables. The Kaplan-Meier method was used to estimate the cumulative risk of subsequent shoulder procedures, and the proportional hazards model was used to estimate hazard ratios (HRs). Results: The grafting and transfer groups were similar in Narakas type, preoperative AMS scores, and shoulder subluxation. The mean postoperative shoulder external rotation AMS scores were 2.70 in the grafting group and 3.21 in the transfer group, with no difference in shoulder external rotation recovery between the groups (difference, 0.51 [95% confidence interval (CI), −0.31 to 1.33]). A greater proportion of the transfer group (24%) achieved an AMS score of >5 for shoulder external rotation compared with the grafting group (5%) (odds ratio, 5.9 [95% CI, 1.3 to 27.4]). Forty percent of the transfer group underwent a secondary shoulder surgical procedure compared with 53% of the grafting group; this was a significantly lower subsequent surgery rate (HR, 0.58 [95% CI, 0.35 to 0.95]). Conclusions: Shoulder external rotation recovery in brachial plexus birth injury remains disappointing regardless of surgical technique, with a mean postoperative AMS score of 3, 17% of infants achieving an AMS score of >5, and a high frequency of secondary shoulder procedures in this study. Spinal accessory nerve to suprascapular nerve transfers were associated with a higher proportion of infants achieving functional shoulder external rotation (AMS score of >5) and fewer secondary shoulder procedures.
