Supracondylar farctures of the humerus are one of most frequently encountered entities in orthopaedic practice. A multitude of the classification systems have been propounded time to time, although Modified Gartland is the most widely used world wide. Gartland type I fractures (undisplaced) are managed conservatively, while as for displaced fractures closed reduction and percutanous pinning (CRPP) is the accepted gold standard. However, there are many instances in which open reduction remains to be the only option available to fix these fractures. In our study, we compared the results of a posterior triceps splitting approach with a lateral approach in open reduction and fixation of these fractures. According to the inclusion and exclusion criteria, we selected 57 patients, which were divided into two groups: Group 1 (n=45) in which posterior triceps splitting approach was used and Group 2 (n=12) in which lateral approach was used. Flynn criteria was used for outcome analysis. The mean fracture union time in Group 1 and Group 2 was 45.3 days and 46.4 days, respectively (P Value < 0.05). Patient or parent satisfaction in Group 1 was 72% while as it was 74% in group 2 (P value < 0.05). Time taken to return to near complete range of motion was 58.5 days in Group 1 and 58.9 days in group 2 (P Value < 0.05). Hence, we conclude that for displaced supracondylar fractures of humerus, when open reduction is inevitable, use of posterior triceps splitting approach is a safe method with results comparable to the lateral approach.
