Suspension Arthroplasty Versus Interposition Arthroplasty in the Treatment of Trapeziometacarpal Osteoarthritis: a Clinical and Magnetic Resonance Imaging Study

Biological arthroplasties are the most used surgical techniques, for the treatment of trapeziometacarpal osteoarthritis; all of them provide the reconstruction of trapeziometacarpal joint by a tendon graft. The aim of the study is to compare two surgical techniques: interposition arthroplasty and suspension arthroplasty at 12-month follow-up in order to evaluate the clinical and radiographic results.
