Research summary
Trapeziectomy alone and Trapeziectomy with ligament reconstruction tendon interposition (LRTI) are both recommended treatments for patients with carpometacarpal arthritis of the thumb. Both procedures can be readily performed under local anaesthetic as day case procedures. Our standard practise is to perform a trapeziectomy with an LRTI.
Research into the biomechanical outcome of a trapeziectomy alone vs trapeziectomy with an LRTI is lacking. The only available published research is in cadaveric studies. Whilst these anatomical studies have been conducted to a high standard, they do not provide in vivo results. Furthermore, they are not controlled to each patient and thus are confounded by the differing premorbid biomechanical properties in different individuals’ hands.
We want to perform pressure readings for pinch grips preceeding trapeziectomy, following trapeziectomy and following LRTI for participating patients. This would allow us to biomechnaically assess whether there is a difference in pinch grip between trapeziectomy and trapeziectomy and LRTI which is case controlled to each patient.
