ObjectiveReduction of pain and gain of functionality in symptomatic osteoarthritis of the first carpometacarpal joint.IndicationsIdiopathic, rheumatic, or posttraumatic osteoarthritis of the first carpometacarpal joint. RELATIVE CONTRAINDICATIONS: Poor general condition, poor condition of the hand's soft tissue/skin, chronic regional pain syndrome, current or recent infections of the hand, heavy manual labor (decision on a by-case basis).Surgical TechniqueSupine position, hand pronated or slightly tilted. Upper arm tourniquet (Esmarch's method). Loupe magnification. Incision over the first extensor compartment. Exposure and incision of the thumb's basal joint. Resection of the trapezium. Exposure of the abductor pollicis longus (APL) tendon. Longitudinal split of the tendon harvesting the distally based ulnar part of the tendon. The split APL tendon is wrapped around the flexor carpi radialis (FCR) muscle tendon, suturing it to the tendon and back to itself. The rest of the split APL tendon is placed into the gap between the scaphoid and the first metacarpal bone, which is followed by wound closure.Postoperative ManagementPlaster cast (thumb abduction splint) for 4 weeks. Stable commercially available wrist brace for at least 2 more weeks.ResultsThere were no significant differences between the FCR arthroplasty (Epping's method) and the APL arthroplasty (Wulle's technique) regarding pain (visual analog scale), disability/usability (DASH score), or range of motion. Patients who had undergone APL arthroplasty showed significantly better grip and pinch strength. Furthermore, the operating time was significantly shorter and scars were significantly smaller in APL arthroplasty.
