Surgical Approach for Sciatic Nerve Entrapment Secondary to Biopolymer Injection.

Abstract

The patient presented with a history of deep injection of a nonmedical substance (biopolymer) into the gluteal region, resulting in compression of the sciatic nerve. The surgical technique used to remove biopolymers from the subcutaneous tissue, muscle tissue, and sciatic nerve is described. A structured review of the current surgical approaches for the sciatic nerve was conducted. The preoperative evaluation, intraoperative technique, and postoperative follow-up of the clinical case are detailed. The described surgical approach effectively decompresses the sciatic nerve, removes the biopolymer material from the subcutaneous tissue and muscle tissue, and improves symptoms, cosmetic outcomes, recovery time, and the need for additional surgery. Given the limited information on the management of biopolymer removal and nerve compression, this technique represents a viable alternative, offering benefits in recovery and cosmetic outcomes.
