TRAP vs. Olecranon Osteotomy in Intra-Articular Distal Humerus Fractures: A Comparative Study

Abstract

Background and Objectives: Various approaches can be employed for the management of intra-articular distal humeral fractures. This study aims to assess and compare the functional outcomes associated with two distinct approaches: one involving olecranon osteotomy and the other utilizing the triceps-lifting approach (TRAP) for treating intra-articular distal humeral fractures.
Materials and Methods: A total of 17 patients in Group A were juxtaposed with an equal number in Group B. Both groups demonstrated similarity concerning age, gender distribution, duration of injury, and the extent of fracture comminution. Comparative analyses encompassed operative duration, hospital stay, union rates, range of motion, and complications. The assessment of functional outcomes utilized the Mayos’ elbow performance score (MEPS).
Results: Patient follow-up extended for a minimum of 12 months. Fracture union occurred at or before 4 months for all patients in both groups, except for one case in Group A where union was observed at 8 months. The average time to union exhibited comparability between the two groups. The overall range of motion was akin in both groups. No statistically significant differences were discerned between the two groups concerning mean MEPS. The cumulative complication rate was 38% in the TRAP group and 28% in the olecranon osteotomy group.Conclusion: Surgical intervention is imperative for optimal functional outcomes in intraarticular distal humerus fractures. Despite its technical intricacy, the TRAP exposure emerges as a viable alternative to the olecranon osteotomy approach. Both methodologies demonstrate comparable clinical and functional outcomes in the management of intra-articular distal
humerus fractures.
