Area of Science:

  • Orthopedic Surgery
  • Radiology
  • Nerve Surgery

Background:

  • Proximal hamstring avulsion repair necessitates sciatic nerve mobilization.
  • Mobilization difficulty correlates with scar tissue and nerve adherence.
  • Predicting challenging sciatic nerve dissection has been a clinical gap.

Purpose of the Study:

  • Identify clinical and radiological predictors of difficult sciatic nerve dissection during proximal hamstring repair.
  • Develop tools to anticipate intraoperative challenges in these repairs.

Main Methods:

  • Retrospective review of 67 patients undergoing proximal hamstring repair.
  • Analysis of medical records and preoperative magnetic resonance imaging (MRI).
  • Comparison between patients with and without difficult sciatic nerve dissection.

Main Results:

  • Factors predicting difficult dissection include complete conjoint tendon avulsion, greater tendon retraction, sciatic nerve imaging abnormalities, and circumferential hematoma.
  • The Sciatic Nerve Dissection Score showed 53% positive and 88% negative predictive values at a threshold of 23.
  • A decision tree achieved 75% positive and 87% negative predictive values.

Conclusions:

  • Imaging factors predict sciatic nerve scarring and adherence, indicating difficult dissection.
  • Novel methods, the Sciatic Nerve Dissection Score and a decision tree, can predict dissection difficulty.
  • These tools aid in preoperative planning for proximal hamstring repair surgeries.
