Abstract
GA Robertson, C Hong, CD Zimmerman. The abductor pollicis longus: A key to basal joint surgery. Can J Plast Surg 1993;1(1):30-35. Anatomical studies show that the abductor pollicis longus acts primarily as a radial deviator of the wrist and as the main stabilizer of the basal joint of the thumb. An advancement and reinforcement technique of this muscle is used in conjunction with a standard silastic replacement arthroplasty for osteoarthritis of the trapezio-metacarpal joint. Excellent postoperative stability is achieved together with good pain relief and improvement in strength.
