Arthroscopic-assisted percutaneous reduction and screw fixation of displaced scaphoid fractures.

Abstract

Many scaphoid fractures can be treated with percutaneous screw insertion, but fracture displacement usually necessitates open reduction. Two surgeons treated 20 consecutive patients with displaced fractures of the scaphoid using arthroscopic-assisted percutaneous screw fixation. Thirteen patients had dorsal (antegrade) and seven had palmar (retrograde) percutaneous screw insertion. At an average follow-up of 18 (range 6-48) months, all of the fractures were healed and there were no implant problems. The early results of arthroscopic-assisted percutaneous screw fixation of displaced fractures of the scaphoid suggest that union can be obtained and good to excellent function achieved predictably without the need for open exposure. Avoidance of an open exposure limits wrist ligament injury and may preserve blood supply. Further evaluation of this procedure is merited.
