Comparison of Thumb Metacarpophalangeal Arthrodesis to Volar Plate Capsulodesis for Metacarpophalangeal Hyperextension in the Setting of Basal Joint Arthritis—A Case-Control Study

Our LRTI + C cohort experienced persistent MCP hyperextension, with mean postoperative hyperextension of >30°. Despite the literature suggesting that this portends inferior outcomes, our LRTI + C cohort demonstrated near-equal outcomes when compared with the LRTI, LRTI + A, and control groups. We no longer perform capsulodesis for MCP hyperextension and offer arthrodesis for MCP arthrosis or hyperextension not actively correctable by the patient.
