Comparing Motion Outcomes In Salvage Procedures For Wrist Arthritis, Stacy Fan

Electronic Thesis and Dissertation Repository

Scaphoidectomy and four corner fusion (4CF), and proximal row carpectomy (PRC) are salvage procedures that may be offered in advanced wrist arthritis. The optimal clinical treatment remains unclear. Biomechanical studies comparing outcomes of these procedures often only report uniplanar motion, rather than multiplanar motion which is more representative of functional wrist motion. Further, the impact of altering the relationship of the proximal and distal carpal rows in the coronal plane during 4CF has not been well-studied.

The purpose of this in-vitro biomechanical study was to quantify changes in wrist kinematics during wrist flexion-extension, radial-ulnar deviation, and circumduction in “anatomic 4CF”, …
