A Retrospective Review of Differences in Complication Rates between Dorsal Percutaneous and Mini-Open Surgical Fixation of Scaphoid Fractures

Abstract Objective  We retrospectively reviewed the complications of 80 cases of scaphoid screw fixation in acute fractures and early nonunions comparing dorsal percutaneous and mini-open approaches. Methods  We performed a chart review of all patients who underwent surgical fixation of a scaphoid fracture or a nascent nonunion using a dorsal percutaneous or dorsal mini-open technique by a single surgeon. We collected data on patient demographics, including age and smoking status, time to surgery, fracture type, union, and the major and minor complications that occurred in each group. Fisher's exact tests were used to compare the complication rates between the groups. Results  We identified 80 patients who underwent surgical fixation. Of these, 44 underwent percutaneous fixation and 36 underwent mini-open fixation. All fractures went on to heal. There was a total of five complications identified. There were no major complications in the percutaneous group, but one major complication in the mini-open group (a delayed union that eventually healed at 6 months). There were two minor complications in each group. There was no statistically significant difference in total, major, or minor complication rates between the groups. Conclusions  This study suggests that a dorsal percutaneous surgical technique for scaphoid fracture repair does not affect the complication rate despite prior literature to the contrary. Both techniques analyzed produce excellent rates of union with very low complication rates. Surgeon-specific technique rather than operative approach or exposure may be responsible for previously reported complication rates in the fixation of scaphoid fractures. Level of Evidence  This is a level III, therapeutic study

The Effect of Thursday Night Games on In-Game Injury Rates in the National Football League

Background: Although claims of increased injury rates with Thursday night National Football League (NFL) games exist, a paucity of data exist substantiating these claims. Purpose: To evaluate the effect of rest between games on in-game injury rates as it pertains to overall injury incidence, location, and player position. Study Design: Descriptive epidemiologic study. Methods: Data were obtained from official NFL game books for regular season games from all 32 teams for the 2013-2016 seasons. All in-game injuries recorded in official game books were included. Rest periods between games were classified as short (4 days), regular (6-8 days), or long (≥10 days). Overall observed injury rates per team-game were analyzed in relation to different rest periods using negative binomial regression. For results with significant overall findings, pairwise comparisons were tested using the Wald chi-square test. Exploratory secondary analyses were performed in a similar fashion to assess differences in injury rates for the different rest periods when stratified by anatomic location and player position. Results: A total of 2846 injuries were identified throughout the 4 seasons. There was an overall significant difference in injuries per team-game between short, regular, and long rest ( P = .01). With short rest, an observed mean of 1.26 injuries per game (95% CI, 1.06-1.49) was significantly different from the 1.53 observed injuries per game with regular rest (95% CI, 1.46-1.60; P = .03), but not compared with the 1.34 observed injuries per game with long rest ( P = .56). For player position, only the tight end, linebacker, and fullback group demonstrated significant differences between the injury rates for different rest categories. Quarterback was the only position with more injuries during games played on Thursday compared with both regular and long rest. This specific analysis was underpowered and the difference was not significant ( P = .08). No differences were found regarding injury rates in correlation with differences in rest periods with different injury locations. Conclusion: A short rest period between games is not associated with increased rates of observed injuries reported in NFL game books; rather, our data suggest there are significantly fewer injuries for Thursday night games compared with games played on regular rest. Future research correlating rest and quarterback injury rates is warranted
