Reoperation Rate and Indication for Reoperation after Free Functional Muscle Transfers in Traumatic Brachial Plexus Injury
plexus injury. Few studies report the rate of revision surgeries following free functional muscle transfers. We examinedthe reoperation rate and indication for reoperation after primary reconstruction of upper extremity function with a freegracilis transfer after brachial plexus injury.
From 2003-2016, we identified 25 patients who underwent a free functional gracilis muscle transfer forrestoration of upper extremity function. We reviewed their medical charts to record patient, injury, and treatmentcharacteristics. Indication for reoperation and reoperative procedure were also identified.
Fourteen out of 25 patients (56%) had a reoperation after FFGT. Four flaps were re-explored for vascularcompromise, but there were no flap failures. The majority of reoperations involved adjustment of tendon excursion(8/14) which demonstrated that tenolysis was the main procedure.
Despite promising results of free functional gracilis transfers, reoperation is relatively common and shouldbe discussed with the patient as a preoperative strategy. Early exploration of vascular compromise may decrease theflap failure. Poor tendon excursion is a common unpredicted consequence after FFMT and is the main indication forreoperation.Level of evidence: IV
