Summary
Nerve variations near the piriformis muscle were studied in cadavers. Most nerves were in typical positions, but some pierced or had unusual locations, impacting surgical approaches.
Area of Science:
- Anatomy
- Surgical Anatomy
- Neuroanatomy
Background:
- The piriformis muscle is in the deep gluteal region.
- Nerve variations can complicate surgical procedures.
Purpose of the Study:
- To examine the anatomical relationship between nerves and the piriformis muscle.
- To identify variations in nerve positioning relative to the piriformis muscle.
Main Methods:
- Dissection of 50 buttock specimens from adult and newborn male cadavers.
- Documentation of nerve positions relative to the piriformis muscle.
Main Results:
- Nerves were in the usual position in 74% of specimens.
- One or more nerves perforated the piriformis muscle in 16% of specimens.
- Unusual nerve locations with an intact piriformis muscle were observed in 10% of specimens.
Conclusions:
- Anatomical variations of nerves in the deep gluteal region are common.
- Understanding these variations is crucial for surgical planning and avoiding nerve injury.
