This broader classification is now called deep gluteal syndrome, of which piriformis syndrome is one cause. [ 79 ] [ 29 ] Today piriformis syndrome is in the same place herniated disk once were - there is a link between the pathophysiology and the symptoms (it's clear why the most studied treatments work), but piriformis syndrome does not have ...
The all encompassing term "deep gluteal syndrome" was developed to appreciate the many causes of non-discogenic sciatic nerve entrapment in the deep gluteal space. Piriformis syndrome is now considered one of many causes of deep gluteal syndrome. [1] 1947 - Piriformis syndrome described. [31] 1999 - Deep gluteal syndrome is proposed to replace ...
Piriformis syndrome occurs when the piriformis irritates the sciatic nerve, which comes into the gluteal region beneath the muscle, causing pain in the buttocks and referred pain along the sciatic nerve. [8] This referred pain is known as sciatica. Seventeen percent of the population has their sciatic nerve coursing through the piriformis muscle.
[20] [21] There are now many known causes of sciatic nerve entrapment, such as fibrous bands restricting nerve mobility, that are unrelated to the piriformis in the deep gluteal space. Deep gluteal syndrome was created as an improved classification for the many distinct causes of sciatic nerve entrapment in this anatomic region. [21]
Many large and small muscles have relationships with the ligaments of the sacroiliac joint including the piriformis (see "piriformis syndrome", a condition often related with sacroiliac joint dysfunction), rectus femoris, gluteus maximus and minimus, erector spinae, latissimus dorsi, thoracolumbar fascia, and iliacus.

Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve , though this may also refer to nerve root compression (by a herniated disc , for example).
More difficult exercises may include the incorporation of resistance training (weights), gym equipment and more explosive movements. Other exercises such as cycling (stationary), swimming and water-based activities have also been found to strengthen and improve overall stability and strength in the core, lower back and hips. [20]
The nerve also courses between the gluteus medius and minimus. The superior gluteal artery also supplies the tensor fasciae latae. [1] The superior gluteal nerve arises from the sacral plexus and only has muscular innervation associated with it. There is no cutaneous innervation for sensation that stems from the superior gluteal nerve. [2]
