“…Since physical therapy was considered inadequate, surgical correction [2,3,5] of both the possible causes of piriformis syndrome was performed in perspective of a highly probable good outcome [1,3,8]. The initially slow clinical improvement and the incomplete long-term resolution of the pain registered in our case may be attributed to the very long history of the disease and the clinical condition before surgery as well as the concomitancy of two irritating causes on the nerve.…”

“…a hypertrophic piriformis muscle and a neurovascular conflict consisting of an abnormal and absolutely rare arterial loop intimately abutting on the sciatic nerve. Diagnosis was based on some clinical criteria [2,6] corresponding to the typical requirement of the piriformis syndrome [3] and on the instrumental negativity for spinal or radicular pathologies.…”

“…Before the advent of magnetic resonance imaging (MRI), the clinical suspicion of the syndrome arose when common etiologies for spinal pain were excluded. Beside the more frequent causative factors represented by anomalies of the piriformis muscle [1,2], sometimes associated with a fascial constricting band around the nerve [1,3], vascular malformations [4,5] are rarely implicated in piriformis syndrome.…”

Notwithstanding the advent of magnetic resonance imaging (MRI), some etiologies of piriformis syndrome continue to remain obscure and elude this investigation. We report a case characterized by a long history and a clinical picture both typical of piriformis syndrome, caused by hypertrophy of the piriformis muscle clearly demonstrated at MRI. At surgery, we also found a likely neurovascular conflict not documented by MRI, consisting of an intimate relation between the sciatic nerve and the inferior gluteal artery.Following the surgical correction of both possible sources of pain, the patient experienced a slowly progressive relief of the sciatica.

Piriformis syndrome is an uncommon condition characterized by sciatic nerve entrapment at the greater sciatic notch. Nonoperative treatment such as physical therapy, nonsteroidal antiinflammatory drugs, and local injections often results in relief of symptoms. For patients who do not benefit from nonoperative therapy, surgical exploration and decompression of the sciatic nerve has been effective. However, the success of surgery may be diminished by scar formation or hematoma in the anatomically restricted sciatic notch. We report two patients with piriformis syndrome who responded primarily to surgical decompression and had recurrent symptoms resulting from scar tissue formation in the sciatic notch. On revision surgery, polytetrafluoroethylene pledgets were placed around the sciatic nerve to avoid compression and entrapment by scar tissue. Both patients had satisfactory outcomes at 3 years followup.

“…Surgical release with relief of symptoms has also been reported ( 0,1 ). Functional loss after this procedure is minimal as the piriformis muscle is only the fourth strongest of the short external rotators of the hip (12).…”

Wheelchair-confined patients with neuromuscular diseases are vulnerable to the piriformis syndrome. This syndrome, a not uncommon cause of entrapment sciatic neuritis, has a typical presentation, is easily diagnosed by placing direct or indirect tension on the piriformis muscle, and can be managed with injection of local anesthetic and steroid into the muscle augmented by tone relaxation including passive stretch.
