Summary
Superior gluteal nerve injuries are serious hip surgery complications. Dissection reveals nerve branching patterns, proposing a 2-3 cm safe zone above the greater trochanter to prevent damage.
Area of Science:
- Anatomy
- Orthopedic Surgery
- Neuroscience
Background:
- Superior gluteal nerve injuries are significant complications during hip surgery.
- Precise anatomical knowledge of the superior gluteal nerve's course is crucial for surgical safety.
Purpose of the Study:
- To precisely map the superior gluteal nerve's branching patterns and anatomical landmarks.
- To establish a safe surgical zone to minimize the risk of nerve damage during hip procedures.
Main Methods:
- Dissection of 19 adult cadaveric half pelves (10 male, 9 female).
- Measurement of distances and angles from nerve entry points to the greater trochanter.
- Statistical analysis of anatomical data.
Main Results:
- The superior gluteal nerve typically bifurcated (89.48%) or trifurcated (10.52%) after exiting the pelvis.
- The caudal branch consistently innervated the tensor fascia latae muscle.
- Defined measurements and angles for nerve entry into gluteal muscles.
Conclusions:
- A 2-3 cm safe area superior to the greater trochanter is proposed.
- This anatomical understanding and defined safe zone can help prevent superior gluteal nerve injury in hip surgery.
