Surgical Management of Proximal Interphalangeal Joint Repetitive Stress Epiphyseal Fracture Nonunion in Elite Sport Climbers.

Abstract

Repetitive stress fracture of the middle phalanx epiphysis is an injury specific to elite adolescent sport climbers. As sport climbing becomes increasingly popular in younger age groups, an increased number of these injuries have been reported in recent years. To date, treatment of these fractures has been nonsurgical, with strict rest and physiotherapy prescribed until fracture union. However, when these patients present in a delayed fashion with an established nonunion, nonsurgical treatment may fail, leading to disabling chronic pain and/or digital deformity in some cases. In this article, we present 2 cases of surgical treatment for finger middle phalanx repetitive stress epiphyseal fracture nonunion, using a percutaneous spot drilling epiphysiodesis technique.
