Conduit-assisted Allograft Neurorrhaphy for the Treatment of Intractable Lower Extremity Pain Due to Neuromas-in-continuity
Background:. We present a novel technique for the management of intractable lower extremity pain, due to neuromas-in-continuity of two peripheral nerves, through combined neurectomies proximal to the zone of initial injury and subsequent bridging utilizing an allograft-coupled conduit construct.

| Sumario: | Background:. We present a novel technique for the management of intractable lower extremity pain, due to neuromas-in-continuity of two peripheral nerves, through combined neurectomies proximal to the zone of initial injury and subsequent bridging utilizing an allograft-coupled conduit construct.
Methodology:. A retrospective chart review of 36 patients (18 women and 18 men) with recalcitrant nerve pain secondary to neuromas-in-continuity of two peripheral nerves following lower extremity trauma was conducted. Subjects underwent superficial peroneal nerve (SPN) to deep peroneal nerve neurorrhaphy (19 patients) or SPN to sural nerve neurorrhaphy (17 patients) proximal to the zone of initial injury. Patient demographics, comorbidities, procedure details, complications, and preoperative and postoperative pain assessments using a visual analog scale were evaluated.
Results:. Residual nerve pain from previous lower extremity trauma was included. Analysis of preprocedure and postprocedure visual analog scale scores demonstrated a mean decrease of 7.45 points (mean: pre 8.89, mean: post 1.44). All patients voiced satisfaction with postoperative ambulatory tolerance and pain relief at last follow-up (mean: 30.86 months).
Conclusions:. The sequelae of neuromas-in-continuity of the SPN, deep peroneal nerve, and sural nerves were noted to have significantly improved with proximal neurectomy and subsequent bridging utilizing a nerve allograft and conduit construct. We present this coaptation technique as a viable treatment option for reduction in neurogenic pain involving peripheral nerve injury of two dermatome distributions. |
