Trapeziectomy with ligament reconstruction and tendon interposition arthroplasty in a male cohort : a retrospective study.

Osteoarthritis of the carpometacarpal joint of the thumb is a common disease, mostly affecting middle aged women. This article presents the results of a trapeziectomy with a ligament recontruction/tendon interposition procedure. We evaluated 60 male patients with 76 operated thumbs. The mean follow- up was 62 months (ranging from 13 to 133 months, with SD of 33 months). The outcome was measured with the disabilities of the arm, shoulder and hand score, a Nelson Hospital score, a Visual analogue scale score and range of motion. The preoperative height of the trapezium was measured and compared with the height of the trapezial space postoperativaly. The disabilities of the arm, shoulder and hand score improved from 25.6 to 16.1. The Visual analogue scale score for pain, satisfaction, dexterity and funcion were correlated with each other. On x-ray, there was an average loss of 67% of trapezial height compared preoperativaly with postoperativaly, but no correlation was found with clinical outcome parameters.
