Discussion

This technique shows improved operability for exposing the sciatic nerve in the gluteus maximus, suggesting less muscle damage.

The modified technique offers a surgical pathway with only partial detachment of the gluteus maximus muscle.
Only a slight decrease in the angle of the surgical corridor is noted compared to traditional methods.
Utilizing this approach may prevent muscle damage associated with muscle deafferentation during surgery.
Illustrative case supports the feasibility and efficacy of this alternative method for sciatic nerve exposure.

Gagliardi et al. (2025) studied this question.
