“…A range of commercial products, including de-cellularized nerve allografts and collagen-based or synthetic nerve guides/conduits, have been developed, and their application in peripheral nerve repair has been extensively reviewed (see for example Arslantunali, et al Khoe et al and Kaushik and Hammert) [15][16][17]. Although autologous tissues, such as muscles and/or veins, may also be used to form a nerve conduit, commercial products are available off-the-shelf and minimize the time needed for tissue harvesting and conduit preparation.…”

Background Recovery of sensibility after digital nerve injury is crucial for restoring normal hand function. We evaluated long-term outcomes of digital nerve reconstruction with autografts. Methods This retrospective study included patients who underwent secondary reconstruction of digital nerves with nerve autografting. Recovery of sensibility was evaluated based on the following: patient self-assessment, two-point discrimination (2PD), and a total sensation score (sum of proprioception, temperature sensation, and sharp/dull discrimination). Mixed models regression was used to study predictors of sensibility outcomes. The predictors analyzed were age, sex, smoking status, number of fingers involved in a patient (as a measure of injury severity), time to reconstruction, and time to follow-up. Results In 61 patients, 174 digital nerves in 126 fingers were reconstructed after an average of 33.1 weeks from injury. The mean follow-up was 6.4 years from reconstruction. The mean graft length was 3.6 cm. Self-rated sensibility in the affected area was very good in 13% of patients, good in 33%, satisfactory in 40%, and poor in 24%. 2PD at 6 mm was present in 17% of patients, at 10 mm in 12%, and at 15 mm in 18% (mean 2PD was 10.8). Proprioception was preserved in 107 (85%) fingers, sensation of temperature was preserved in 99 (75%) of fingers, and sharp/dull discrimination in 88 (70%) fingers. Time from injury to reconstruction was the only significant predictor of the total sensation score. Conclusion Our data indicate that earlier reconstruction is associated with a favorable outcome.
