The Outerbridge-Kashiwagi (O-K) procedure has conventionally been used for the treatment of osteoarthritis of the elbow and to treat posttraumatic sequelae including posttraumatic arthritis, stiffness, contracture, and ulnar neuritis. The procedure involves exposure of the posterior elbow joint as well creating a window posteriorly through the olecranon fossa to target anterior aspects of the elbow. Several case series have shown the O-K procedure to have good functional outcomes with minimal complications. Used mostly for the surgical treatment of adult osteoarthritis, the O-K procedure has not been previously described for the treatment of a pediatric supracondylar humerus fracture malunion. This article and accompanying video will present the pearls and discuss the technique of the O-K procedure used to treat the loss of elbow flexion as a sequelae of supracondylar humerus fracture malunion.
