Functional outcome of intraarticular distal humerus fracture
Background : Displaced intraarticular distal humerus fracture has been conventionally treated operatively with various triceps disrupting approaches. These approaches are associated with several complications, such as triceps weakness, nonunion or delayed union of osteotomy, implant prominence, and delayed mobilization of the elbow. We present the functional outcome of intraarticular distal humerus fracture fixation using a triceps-sparing paratricipital approach which allows early elbow mobilization and preserving triceps strength.

Materials and Methods : Twenty five patients with intraarticular distal humerus fracture were operated using triceps-sparing paratricipital approach with orthogonal plate construct. There were 16 male and 9 female patients and average age was 42.16 years (range 23-65 years). The mechanism of injury was fall from height (n = 8), road traffic accident (n = 13) and ground level fall (n = 4). Clinical, radiological, and functional assessment with Mayo Elbow Performance Index (MEPI) were obtained at follow up period.

Conclusion : Open reduction and internal fixation of intraarticular distal humerus fractures with triceps-sparing paratricipital approach provide adequate exposure with no adverse effect on triceps muscle strength and allows early initiation of elbow motion. We analyzed, age and injury to surgical interval with relation to functional range of elbow using Z-test which is insignificant.
