Abstract
Background: Amputated neuromas, a common consequence of peripheral nerve injury, can cause significant pain and may impair daily life. Herein, we conducted a retrospective study on patients who underwent a nerve-capping technique using the bioabsorbable nerve conduit Renerve®, with a minimum follow-up period of 6 months. Methods: We conducted a retrospective study to assess patients with amputation neuromas of the finger or palm who underwent surgical treatment using the capping technique with the Renerve® conduit between October 2018 and September 2022. The data on demographics, operative details, pre- and postoperative evaluations (visual analogue scale [VAS] pain scores and Tinel sign) and complications were analysed. Results: Seven patients (seven nerves) with a median age of 51 years (three men and four women) were assessed. The median follow-up duration was 15 months. Renerve® conduits of varying sizes (1.0-2.3 mm) and lengths (15-25 mm) were used. The median duration until surgery was 195 days. After the procedure, VAS pain scores significantly decreased from a baseline of 53.1 mm to 5.7 mm at the 6-month follow-up. Tinel sign persisted in four patients, and no postoperative complications occurred. Conclusions: Our study demonstrates the clinical usefulness of the Renerve® conduit as a nerve-capping technique for amputation neuroma. Considering the limited availability of real-world data on Renerve® conduits for nerve capping, our findings provide valuable insights for clinical practitioners. Level of Evidence: Level IV (Therapeutic).
