PurposeTo update the evidence on the clinical features of the piriformis syndrome since the first systematic review published in 2010.MethodA systematic review of all case, cross-sectional and prevalence studies.ResultsThe commonest features reported were: buttock pain, pain aggravated on sitting, external tenderness near the greater sciatic notch and pain on any maneuver that increases piriformis muscle tension, and limitation of straight leg raising. The quality of case reports since the…

This study aimed to assess the value of ultrasound (US) in the diagnosis of PS and found that on US and MRI, the thickness and CSA were increased in PS patients.
Little needle-scalpel for piriformis syndrome
This systematic review will provide an evidence to judge whether Little needle-scalpel therapy for patients with piriformis syndrome is an effective and safe intervention and will provide a comprehensive review of the available evidence for the treatment.
Overview of the anatomical basis of the piriformis syndrome-dissection with magnetic resonance correlation
Clear osseous landmarks are established that may help evaluate associations and possible nerve compressions on pelvic MRI examination to identify the piriformis syndrome and to differentiate it from other causes of internal pudendal neuralgia.

A less well known cause of sciatica is impingement of the nerve trunk from a range of musculoskeletal conditions that compress the sciatic nerve as it passes through the confines of the deepgluteal space, termed the deep gluteal syndrome (DGS).
Deep gluteal syndrome as a cause of posterior hip pain and sciatica-like pain.
This comprehensive review aims to provide the latest information about the epidemiology, aetiology, pathology, clinical features, diagnosis, and treatment of deep gluteal syndrome.
Is it painful to be different? Sciatic nerve anatomical variants on MRI and their relationship to piriformis syndrome
This large-scale correlative radiologic study into the relationship between sciatic nerve variants and piriformis syndrome calls into question this purported relationship.
‘Hand on hip’ sign: A novel screening test and diagnostic tool in piriformis syndrome
A pose used by the patients to describe the pain in the gluteal region in cases of suspected piriformis syndrome is found and is described as ‘hand on hip sign’ (HHS), which serves as an effective screening test in the identification of piriformIS syndrome.


The clinical features of the piriformis syndrome: a systematic review
The most common features found in sciatica patients with and without disc herniation or spinal stenosis were: buttock pain, external tenderness over the greater sciatic notch, aggravation of the pain through sitting and augmentation of thePain with manoeuvres that increase piriformis muscle tension.

Piriformis syndrome in an incomplete paraplegic patient: a case report
The first reported case of PS in a patient with SCI, diagnosed and treated as the piriformis syndrome, is presented, keeping in mind as a pain generator, especially in active and ambulatory SCI patients.
A rare cause of a piriformis syndrome.
" short leg" is one of the rare causes of piriformis syndrome and can be seen alone or with the other causes, and the injection on Piriformis muscle could be more effective for the patients who have PS after the "short leg" treated.
Prevalence of piriformis syndrome among the cases of low back/buttock pain with sciatica: A prospective study
Piriformis syndrome is one of the differential diagnoses of low back/buttock pain with Sciatica and individuals of all activity levels can be affected.
The piriformis muscle syndrome: a simple diagnostic maneuver.
The maneuver described in this report was helpful in diagnosing the piriformis syndrome because it relies on contraction of the muscle, rather than stretching, which the author believes better reproduces the actual syndrome.
Piriformis Syndrome is a cause for Low back pain which is most of the times misdiagnosed as it may mimic with various other conditions. Abnormal condition of the Piriformis muscle such as
Piriform syndrome.
Among a variety of deep muscle trigger points, the piriform muscle trigger point is selected for individual scrutiny by the great potential for confusing this entity with discogenic disease and consequently having unnecessary surgical procedures carried out.
