Clinical Outcome for Surgical Treatment of Traumatic Neuroma With a Processed Nerve Allograft: Results of a Small Prospective Case Series.
Abstract
Processed nerve allografts are used increasingly in the treatment of traumatic neuroma in small sensory nerves. The goal of the present study was to investigate the use of an allograft after different intervals between injury and repair and to analyze results, not only for the success of pain relief, but also for potential recovery of sensation in time. Four patients with painful neuroma in small sensory nerves in the lower extremity were surgically treated with a decellularized allograft. Patients were followed prospectively for at least 1 y. Clinical outcome was assessed using the Likert scale. Recovery of sensation was tested using Semmes-Weinstein monofilaments. In all 4 cases an allograft of 3-cm was used to reconstruct a defect in the superficial peroneal (3) or sural nerve (1) after excision of the neuroma. Complete relief of pain symptoms was achieved in 2 patients: 1 case concerned the reconstruction of a neuroma with an interval of less than 1 y between injury and repair and 1 case a neuroma-in-continuity. Sensation recovered completely in these 2 cases. In the other 2 cases, that had an interval between injury and reconstruction of more than 1 y, there was neither successful pain relief nor recovery of sensation. Thi...Continue Reading

Allogenic & Autologous Therapies
Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
