The Camitz transfer and its modifications: a review

Abstract

The Camitz procedure involves transfer of the insertion of the palmaris longus tendon with a strip of the palmar aponeurosis to the insertion of abductor pollicis brevis in order to improve thumb opposition, and is usually done when severe carpal tunnel syndrome results in complete wasting of the thenar muscles. We carried out a systematic review of the published reports of this procedure. Analysis of available outcome data showed improvement in overall hand function in 86–100% of patients undergoing the original Camitz procedure. Several modifications of the original Camitz transfer have been described, with most focusing on the incorporation and placement of pulleys. All studies are limited by their small sample sizes. Overall, there is a lack of studies comparing the Camitz transfer with other opponensplasty techniques and comparing the various modifications of the original procedure. Level of evidence: IV
