Novel surgical procedure of the half palmaris longus transfer for the opponensplasty of the thumb in patients with carpal tunnel syndrome: A Technical Note. J Nippon Med Sch. 2020 Aug 01;: Authors: Tomori Y, Nanno M, Kentrao S, Majima T Abstract Thumb opposition is an essential movement for daily use of the hand, including precise pinch or grasping as well as fine and complicated hand movement. Although previous studies have reported several donor tendons for opponensplasty, opponensplasty using palmaris longus, Camitz opponensplasty, have been utilized in patients who have loss of opposition function due to long-standing carpal tunnel syndrome, because the procedure involves a simple and useful tendon transfer without causing functional deficits. To obtain enough length to transfer the tendon to the metacarpophalangeal joint of the thumb, the PL tendon should be obtained along with the palmar aponeurosis. However, the palmar aponeurosis is not always available for the opponensplasty, as it occasionally appears thin and is not sufficient for the elongation of the palmaris longus. The extended skin incision over the palm causes painful scar formation or postoperative residual pain. This procedure restores the palmar abduction function of the thumb, but not the opposition function. In the present article, we present the modified Camitz opponensplasty using half split of palmaris longus, which has enough length to anchor to the insertio...
