Abstract
Purpose
Displaced midshaft clavicular fractures are a common injury with a high occurrence rate in young, active individuals. Non-operative care has traditionally been the standard of care for such fractures, but more recent studies have suggested benefits following primary operative fixation. The purpose of this study was to review the literature on displaced midshaft clavicle fractures, identify randomized controlled trials of operative versus non-operative treatment, and pool the functional outcome and complication rates (including nonunion and symptomatic malunion), to arrive at summary estimates of these outcomes.
Method
A systematic review of the literature was performed to identify studies of randomized controlled trials comparing operative versus non-operative care for displaced midshaft clavicle fractures. Meeting abstracts were also searched and included in this study.
Results
Six randomized controlled trials (n=421 patients, mean Detsky score= 15.2) were identified and included. The nonunion rate was higher in the non-operative group (28/207) then it was in patients treated operatively (3/214) (p<0.001). The rate of symptomatic malunion was higher in the non-operative group (15/207) than the operative group (0/214) (p<0.001). The total complication rate was 71 complications in 214 operative cases (33%), and 93 complications in 207 non-operative cases (45%)(p=0.016). The Constant Shoulder scores (CS) and Disability of the Arm, Shoulder and Hand (DASH) scores showed marginally improved (mean 4.1 point increase in CS at one year, mean 5.8 point decrease in DASH at one year) functional values in the operative group: this difference was especially marked in the early post operative period.
Conclusion
Operative treatment provided lower complication rates (especially nonunion and symptomatic malunion) and an earlier functional return compared to non-operative treatment. However, there is little evidence at present to show that the long term effects of operative intervention are significantly superior to non-operative care.
