This study identifies key anatomical sites where the pudendal nerve can be compressed, causing chronic perineal pain. Surgical and nerve block treatments offer significant pain relief for affected individuals.

Area of Science:

  • Anatomy
  • Neuroscience
  • Pain Medicine

Context:

  • Chronic perineal pain, particularly when sitting, is a debilitating condition.
  • The pudendal nerve is implicated in the etiology of this pain.
  • Understanding the anatomical basis of pudendal nerve entrapment is crucial for effective treatment.

Purpose:

  • To investigate the anatomical causes of pudendal nerve entrapment.
  • To correlate anatomical findings with clinical and neurophysiological data in patients with perineal pain.
  • To evaluate the efficacy of nerve blocks and surgical interventions for chronic perineal pain.

Summary:

  • Anatomical dissection of 50 cadavers revealed potential sites of pudendal nerve (PN) conflict, including the ischiatic spine, Alcock's canal, and crossing the falciform process.

  • Pudendal nerve entrapment, possibly between the sacro-tuberal and sacro-spinal ligaments or within the internal obturator muscle fascia, is proposed as a cause of chronic perineal pain.
  • Nerve blocks and a posterior surgical approach were employed, with surgery providing successful pain relief in two-thirds of patients with persistent pain.

    • Impact:

    • Provides detailed anatomical insights into pudendal nerve entrapment.
    • Offers a structured approach to diagnosing and treating chronic perineal pain.
    • Demonstrates the effectiveness of interventional pain management strategies, including surgery, for refractory cases.
