Two-stage extensor tendon graft using the Paneva-Holevitch procedure: A new technique
2018
Abstract Reconstruction of the extensor tendons remains a therapeutic challenge. Tendon transfers and grafts are a potential source of morbidity at the donor site, and the graft stock is limited. In the index finger, the tendon of the extensor indicis proprius can be anastomosed to the tendon of the extensor digitorum, and then the extensor digitorum tendon turned over after being cut at the forearm. We assessed the feasibility of this reconstruction on 12 upper limbs from 6 cadavers and we report the case of a 24-year-old patient who suffered destruction of the extensor apparatus in the index and middle fingers. For the cadaver study, in each case, the tendon could be moved onto the proximal interphalangeal joint, after having done an anastomosis downstream of the extensor retinaculum. The mean graft length was 13 cm (9.7–15.2). This method was used in one clinical case with an excellent outcome. This is a simple technique that is without consequences since the tendons used are already cut, therefore saving a tendon graft. This technique should be part of our therapeutic arsenal.
