Posterior extensile approach to the elbow joint and distal humerus

Between 1986 and 1990, the authors treated 14 intra-articular fractures of the distal humerus using a posterior extensile approach. This approach, a combination of a triceps-splitting approach and an olecranon osteotomy, allows extensive exposure of the posterior aspect of the elbow joint and distal humerus, facilitating fracture reduction. The extensile approach is advocated for intra-articular fractures of the distal humerus with proximal extension. This approach can be extended proximally to the midshaft of the humerus or distally to expose the radial head and the ulnar shaft. The anatomy of the radial nerve and the innervation of the triceps were noted by studying 10 cadaveric elbow specimens.
