Camitz opponensplasty in a patient with advanced carpal tunnel syndrome. ( A ) Incisions and marked thenar atrophy. ( B ) The palmaris longus is harvested with an extension of palmar fascia as shown, prior to distal division and elevation. ( C ) Position of thumb after transfer to the base of the proximal phalanx. Note the line of pull is directed more toward the forearm, making this more of an abductorplasty rather than a true opponensplasty.
