A case series of upper extremity reconstructions utilizing partial ECRB and ECRL tendon autografts

Sources of autografts such as palmaris longus or plantaris are often limited or absent. We present our experience using a low donor-site morbidity method of harvesting strips of extensor carpi radialis brevis and longus (ECRB and ECRL) as free tendon autografts in upper extremity soft tissue reconstructions. Retrospective chart review identified five patients who received reconstructive upper extremity surgeries using ECRB and ECRL partial tendon autografts from January 2014 to October 2021 with at least a 12-month follow-up period. Mayo wrist scores were calculated to demonstrate clinical outcomes. All five patients (mean follow-up: 21 months) were able to return to regular activities while demonstrating improvements in 6- and 12-month postoperative Mayo wrist scores. There was minimal donor site morbidity and no ruptures of parent tendons following harvest. This study provides additional support for utilizing partial strips of ECRB and ECRL in repairing upper extremity tendon gap and ligament deformities.
