Deep Gluteal Space (Posterior Hip)

spatium gluteale profundum

The deep gluteal space is the posterior hip compartment bounded by the posterior hip capsule anteriorly, the gluteus maximus posteriorly, the sacrotuberous ligament medially, and the greater trochanter laterally. It contains the sciatic nerve, the short external rotators, the inferior gluteal vessels, and the posterior femoral cutaneous nerve.

Clinical Notes

Deep gluteal syndrome is an umbrella diagnosis for non-discogenic sciatic nerve entrapment within the deep gluteal space, encompassing piriformis syndrome, obturator internus syndrome, gemelli-quadratus femoris pathology, hamstring origin entrapment, and fibrovascular bands. Hip arthroscopy has enabled endoscopic access to the deep gluteal space for nerve release. MRI with dedicated posterior hip protocol identifies compressive lesions within this space.

Common Injuries & Conditions

Deep Gluteal Syndrome

Sciatic nerve entrapment within the deep gluteal space from various compressive causes producing sciatica without lumbar disc pathology, confirmed by MRI and treated by endoscopic posterior hip decompression.
