BACKGROUND AND OBJECTIVE A less common but important cause of buttock and leg pain known as "Piriformis Syndrome". Piriformis syndrome is all intrinsic pathology of the piriformis itself, such as myofascial pain, anatomical variations, hypertrophy, and myositis ossificans or it is caused by trauma to the pelvis or buttock. In this case report we are going to present a rare cause of piriformis syndrome. CASE REPORT Our first case was a 32 year old woman. She was referred to our pain clinic for…

Development of Unilateral Piriformis Syndrome in a Female with Congenital Leg Length Discrepancy
TLDR
A 22-year-old female soldier who was admitted for lower back pain with soreness radiating to her right buttock and right lower extremity found that she had leg length discrepancy under X-ray finding, which might be caused by short-term compensation in congenital leglength discrepancy.
Four symptoms define the piriformis syndrome: an updated systematic review of its clinical features
TLDR
Piriformis syndrome is at a stage previously encountered with herniated intervertebral disc: its prevalence among low back pain and sciatica sufferers and the diagnostic accuracy of clinical features requires cross-sectional studies free of incorporation and verification biases.
Piriformis syndrome: Does it bother your daily life?
TLDR
Six key features of the piriformis syndrome are described: a history of trauma or direct fall to the buttock; difficulty walking; worsening with squatting or lifting; a sausage-like mass within the muscle; positive straight leg raising test (SLR test) and gluteal atrophy.
Leg length discrepancy as a rare cause of a piriformis syndrome.
TLDR
Two female patients with piriformis syndrome who had a shorter leg on the effected side were presented and it was concluded that a “short leg” is one of the rarer causes of PS and it can be seen alone or in combination with other causal factors.
Retrospective Review of Pyriformis Syndrome-Extra Spinal Sciatica : A Missed Entity .
TLDR
In the present study, retrospectively reviewed charts of patients treated for pyriformis syndrome and their outcome, finding MR diagnosis of the condition is a definitive sign in conjunction with clinical assessment.
Piriformis Syndrome in Fibromyalgia: Clinical Diagnosis and Successful Treatment
TLDR
Piriformis and fibromyalgia syndrome in a 30-year-old young lady, an often missed diagnosis, is described and management of the piriformis syndrome is focused on.
Piriformis syndrome: a case series of 31 Bangladeshi people with literature review
TLDR
In Bangladesh piriformis syndrome is more common in female, especially among housewives, and should be considered as possible diagnosis when sciatica occurs without a clear spine pathology.
Piriformis pyomyositis, an unusual presentation of leg pain post partum – case report and review of literature
TLDR
A case of piriformis pyomyositis involving a parturient is reported and published cases available in the literature are reviewed.
Piriformis Syndrome in Knee Osteoarthritis Patients after Wearing Rocker Bottom Shoes
TLDR
RBS may extend duration of the PS in osteoarthritis patients, and the positive FAIR test ratios, mean NRS scores, and revised ODIs were higher in the KO group than the SN group from 4?12 weeks after treatment.
Hip Pathology: Overload Syndromes
TLDR
This chapter demonstrates a “unified hip theory,” exhibiting how overload of the hip may result in a multitude of pathologies and subsequently a variety of symptoms.

TLDR
Patients who have blunt trauma to the buttock and then have signs and symptoms that are suggestive of lumbar nerve-root compression may have posttraumatic piriformis syndrome.

TLDR
The case of a patient in whom the sciatic nerve was compressed between the piriformis muscle and the roof of the Sciatic notch was reported, and bone-scanning, computerized axial tomography, magnetic resonance imaging, and histopathological testing indicated that the compression was secondary to myositis ossificans of the pirathanis muscle.

TLDR
The technique used in the current study was successful in injecting the medications near the area of the sciatic nerve and into the piriformis muscle and in the patients who received the injections.
Anatomic considerations and the relationship between the piriformis muscle and the sciatic nerve
TLDR
It is confirmed that the sciatic nerve (SN) is prone to be trapped in the test position, and diagnosis of this situation requires dynamic MR and MR neurography study.
