Top 10 Technical Tips and Tricks for Safe Sciatic Nerve Management During Posterior Hip Endoscopy.

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Anatomy

Background:

• Posterior hip anatomy, particularly the sciatic nerve's proximity to the ischium and hamstring origin, is vital for safe posterior hip endoscopy.
• Increasing use of endoscopic techniques for proximal hamstring repair has led to a rise in iatrogenic sciatic nerve injuries, necessitating improved nerve protection strategies.

Purpose of the Study:

• To outline essential anatomical considerations and surgical techniques for safeguarding the sciatic nerve during posterior hip endoscopy and proximal hamstring repair.

Main Methods:

• Utilizing prone positioning with strategic padding to relax the sciatic nerve and increase the ischiofemoral space.
• Meticulous creation of the subgluteal space, including bursa resection, and identification of the fascial veil separating the hamstring tendon from the sciatic nerve.
• Employing fluoroscopy for precise bony resection and assessing ischial width during endoscopic repair and ischioplasty.

Main Results:

• Endoscopic proximal hamstring repair demonstrates significant improvements in pain and function.
• Complications like postoperative neuropathy occur in approximately 8% of cases, underscoring the importance of meticulous sciatic nerve protection.

Conclusions:

• Endoscopic proximal hamstring repair and ischioplasty are effective minimally invasive treatments for proximal hamstring pathology.
• A comprehensive understanding of posterior hip anatomy, strategic positioning, precise portal placement, and careful dissection are critical for minimizing sciatic nerve injury.
