Internal fixation of displaced middle-third clavicle fractures is a widely used treatment but is frequently associated with post-operative complications. The aim of this study is to investigate whether or not using a skin incision along Langer’s lines, as opposed to a traditional transverse incision, reduces complications. We retrospectively reviewed data on 108 patients who underwent open reduction and internal fixation of mid-shaft clavicle fractures between 2014 and 2018. Either an oblique incision along Langer’s lines or a transverse incision was used according to surgeon’s preference. A pre-contoured diaphyseal locking plate was used in all cases. We collected data on fracture classification, minor complications (irritation from plate, chest wall numbness, superficial wound infection) and major complications (irritation from plate necessitating metalwork removal, periprosthetic fracture, deep infection, neurovascular injury and non-union). Statistical analysis was performed using multivariant regression analysis and Fisher’s exact tests. Fifty-seven patients underwent fixation using the oblique incision and 51 via the transverse incision. Age, gender and fracture pattern in the two groups were comparable. There were 14 minor and 6 major complications in the oblique group. In the transverse group, there were 16 minor and 5 major complications. The major complication rate was 10.5% in the oblique group and 9.8% in the transverse group. The overall major complication rate was 10.2%. No statistically significant difference in the rate of complications between the two groups was identified. Based on our data, an incision following Langer’s lines does not reduce the rate of complications following fixation of displaced middle-third clavicle fractures.
