Abstract

Complete thumb ulnar collateral ligament (UCL) injuries usually require primary repair. The ulnar collateral ligament is often torn from its insertion site and reattachment is difficult. Seven patients underwent repair with the Mitek bone anchor (Mitek Surgical Products, Norwood, MA) for complete ulnar collateral ligament disruptions. A Stener lesion was found in four patients. Follow-up examination was at approximately 1 year. All patients regained a stable metacarpophalangeal joint to valgus stress. X-ray films demonstrated accurate placement of the bone anchor with protraction of the metallic wings within cancellous bone. Range of motion revealed a 7% loss of metacarpophalangeal flexion-extension and a 21% loss of interphalangeal motion. Pinch strength in apposition averaged 98% and in opposition 97% of the uninvolved hand. Grip strength was 96% of the contralateral extremity.
