Sub-Gluteus Maximus Fascial Plane and Perineural Hydrodissection as Novel Treatment for Posterior Femoral Cutaneous Nerve Entrapment.

Posterior femoral cutaneous nerve (PFCN) entrapment due to overuse is rarely reported in the literature, and treatment is limited. Conventional treatment includes focused rehabilitation exercises, computed tomography-guided or magnetic resonance (MR)-guided nerve blocks, MR-guided cryoablation, and surgical decompression, but data for treatment validation and efficacy are lacking. Sub-gluteus maximus fascial plane and perineural hydrodissection may offer an effective alternative treatment for PFCN entrapment, especially given reports of successful cases with similar procedural techniques in other anatomical locations and structures.
