Abstract

Purpose

Digital nerve reconstruction with a biodegradable conduit offers the advantage of providing nerve reconstruction while providing a desirable environment for nerve regeneration. Many conduit materials have been investigated, but there have been few reports of human clinical trials of purified type I bovine collagen conduits.

Methods

We report a prospective study of 22 isolated digital nerve lacerations in 19 patients reconstructed with a bioabsorbable collagen conduit. The average nerve gap measured 12   mm. An independent observer performed the postoperative evaluation, noting the return of protective sensation, static 2-point discrimination, and moving 2-point discrimination, and recording the patient’s pain level using a visual analog scale. Minimal follow-up was 12   months and mean follow-up was 20   months after surgery.
