Arthroscopic aided fixation of scaphoid fractures.

Abstract

Acute nondisplaced scaphoid fractures have traditionally been managed with cast immobilization. Although cast immobilization may be successful in approximately 90% of cases, prolonged casting may lead to muscle atrophy, joint contracture, disuse osteopenia, and potential financial hardship. An athlete or worker may be inactive for 6 months or longer as the fracture heals. Arthroscopic assisted fixation offers a middle ground between traditional cast immobilization and open reduction for scaphoid fractures. These techniques reduce exposure and minimize soft tissue dissection with potential loss of vascularity, avoid division of the important radioscaphocapitate ligament, and allow for detection and management of any associated intracarpal soft tissue injuries. This article presents the indications and describes in detail the various applications for wrist arthroscopy in management of scaphoid fractures.
