Abstract
The scaphoid is the most frequently fractured carpal bone. Given its retrograde blood supply, the proximal pole of the scaphoid is at higher risk of nonunion and avascular necrosis (AVN), ultimately resulting in a well-described pattern of wrist arthritis. Surgical intervention prior to the development of advanced arthritis is important, particularly in young, active patients.
Treatment options for AVN of the proximal pole include scaphoidectomy with 4 corner arthrodesis, and, gaining recent popularity, proximal scaphoid reconstruction with the medial femoral trochlea (MFT) graft. The former procedure is a historically favored method to treat collapse of the proximal pole of the scaphoid in younger patients, the disadvantage being loss of normal carpal kinematics that results after the scaphoid is removed and the midcarpal joint is fused. Conversely, reconstruction with the MFT graft preserves the scaphoid and thus theoretically maintains normal intercarpal kinematics. The drawback for this procedure is the potential donor site morbidity and the need for microsurgery. Direct comparison of functional wrist motion after these two surgical procedures has not been reported.

The objective of this study is to directly compare wrist motion following two accepted surgical procedures for patients with scaphoid nonunion and proximal pole avascular necrosis. Wrist kinematics following scaphoidectomy and 4 corner arthrodesis vs. scaphoid reconstruction with the medial femoral trochlea graft will be directly compared using a previously published cadaveric optoelectronic wrist motion simulator at the Hines VA musculoskeletal biomechanics laboratory. Dynamic CT reconstruction will then illustrate the path of flexion, extension and dart thrower's motion.

The ultimate goal of this project is to provide patients with tangible evidence for expected functional results after both procedures, on which they can base their treatment selection.
