Osteoarthritis of the CMC joint of the thumb is common. Various conservative and surgical options to relieve pain and imrpove function exist. Ligament reconstruction tendon interposition (LRTI) is the most common surgery used. However, various types of joint replacement now exist. The purpose of the study is to determine the difference between pre-and post-operative levels of function, pain, range of movement and strength in participants receiving a pyrocarbon CMC joint replacement or the convential surgery using a ligament reconstruction interposition technique. We are investigating the radiographic alignment of the joint and implant complications over a 24 month period. The Clinical Performance of the two different types of surgery will be evaluated with respect to: clinical response (Quick DASH, Patient Rated Wrist Evaluation, pain VAS score, range of motion, grip and pinch strength); radiographic performance and complication rates.
This study is currently recruiting participants.
