About this study

The purpose of this study is to evaluate the basis for three widely held fundamental tenets about surgical intervention for thumb basal joint arthritis; 1. Trapeziectomy with ligament reconstruction and metacarpal stabilization is associated with superior functional outcomes and strength, 2. Preservation of the arthroplasty space correlates with functional outcomes, pain relief, and restoration of strength after basal joint arthroplasty, and 3. Mitigation of metacarpophalangeal joint (MCPJ) hyperextension optimizes postoperative strength after basal joint arthroplasty, regardless of surgical technique. It is hypothesized that thumb basal joint arthroplasty with metacarpal stabilization, by either ligament reconstruction (I) or suture suspension (II), provides greater improvement in grip and pinch strength, and better hand function, than might be achieved following provision of pain relief alone by simple trapeziectomy (III). Preservation of the arthroplasty space will correlate positively, and MCPJ hyperextension will correlate negatively, with improved thumb function and lateral pinch strength. Primary Aims (within 3 procedure cohorts): 1. Compare pre-operative pinch and grip strength as well as patient-reported outcomes (PROs) for pain in patients before and after lidocaine injection of the trapeziometacarpal joint, prior to thumb basal joint arthroplasty; 2. Compare post-operative pinch and grip strength and PROs for pain and function at 3 and 6 months after thumb basa…
