Pinch Grip and Functional Outcomes Between Hematoma Distraction Arthroplasty Versus Ligament Reconstruction Tendon Interposition Arthroplasty in Trapeziometacarpal Osteoarthritis.

To date, there is no gold standard for the treatment of severe trapeziometacarpal joint osteoarthritis. Despite the fact that new procedures have been described, techniques such hematoma distraction or ligament reconstruction tendon interposition are still valid non-implant options. The main hypothesis was that patients treated with LTRI technique would show superior clinical outcomes at one-year follow-up in terms of tip and key pinch and DASH scores in comparison with HDA technique. As secondary objectives, complication rates and surgical times were recorded.
