No results posted yet for this study

Summary

There is currently no consensus on the best surgical approach for carpometacarpal osteoarthritis treatment. Simple trapeziectomy (TI) or trapeziectomy with ligament reconstruction tendon interposition (LRTI) are both accepted procedures but evidence is lacking. We want to conduct a high quality prospective randomized trial in which preoperative and postoperative objective and subjective outcome measures of both procedures will be compared.

In this trial, investigators compare the Weilby procedure (LRTI) to simple trapeziectomy (TI) with shame incisions in patients with severe trapeziometacarpal osteoarthritis. Investigators hypothesize that TI will be equal to LRTI in terms of both subjective and objective outcome measures

Conditions

  • Thumb Osteoarthritis

Interventions

PROCEDURE

Simple trapeziectomy

A curvilinear incision is made over the base of the 1. metacarpal towards the tendon of the extensor pollicis brevis in the distal part of the anatomical snuffbox. The joint is opened as widely as possible and the trapezium is dissected free in a proximal direction until the articulation with the scaphoid is reached. Then trapezium is removed taking care not to damage tendon of the flexor carpi radialis. The joint capsule is closed and skin sutured in the usual manner. At the completion of the procedure two small shame incision are made (1 cm each) involving only epidermis on the volar aspect of the palm and forearm. Each of them will be closed with one stitch

PROCEDURE

Weilby

The first part of the surgical procedure is identical to simple trapeziectomy. In addition, the tendon sheath of the first extensor compartment is divided. After this, a strip consisting of approximately one-third of flexor carpi radialis tendon is dissected using two small incisions on the volar aspect of the wrist and distal forearm. The distally based tendon strip is tunneled to its insertion on the second metacarpal bone. Then the strip of tendon is winded around the abductor pollicis longus tendon and the rest of the tendon at least twice, pulling those tendons together into the space created after excision of the trapezium. The tendons are sutured together with non-absorbable sutures while the skin is sutured in the usual manner
