The deep gluteal region is often encountered when performing injections, when performing surgery such as total hip replacements, or diagnosing problems of this region or lower limbs using clinical or imaging techniques. Previously, the prevalence figures of piriformis and sciatic nerve anomalies have ranged from 1.5 to 35.8% in dissected specimens. This study systematically reviews and meta‐analyses the prevalence of piriformis and sciatic nerve anomalies in humans using previously published…

Is it painful to be different? Sciatic nerve anatomical variants on MRI and their relationship to piriformis syndrome
TLDR
This large-scale correlative radiologic study into the relationship between sciatic nerve variants and piriformis syndrome calls into question this purported relationship.
Composite Anatomical Variations between the Sciatic Nerve and the Piriformis Muscle: A Nepalese Cadaveric Study
Piriformis syndrome is a rare syndrome which is one of the main causes of nondiscogenic sciatica causing severe low back pain due to entrapment of sciatic nerve either by the hypertrophy or by
Sciatic Nerve Variants in Patients Diagnosed With Sciatica: Is There a Correlation?
TLDR
There is strong statistical significance regarding the relationship between sciatic nerve variation and the clinical diagnosis of sciatica and preoperative magnetic resonance imaging can be considered in Sciatica patients to prevent iatrogenic injury in pelvic surgery.

Anatomical variations of the sciatic nerve in a group of Brazilian cadavers *
TLDR
Evaluated characteristics of the sciatic nerve and its relationship to the piriformis muscle in a group of Brazilian cadavers suggested that the painful syndrome may often occur without the anatomical variations.

TLDR
Evaluated characteristics of the sciatic nerve and its relationship to the piriformis muscle in a group of Brazilian cadavers suggested that the painful syndrome may often occur without the anatomical variations.
Surgical and Non-surgical Treatment Options for Piriformis Syndrome: A Literature Review
TLDR
Clinicians should consider medical management and conservative management in the initial treatment plan for piriformis syndrome, and the preference of the endoscopic approach over the open approach due to improved outcomes and decreased complications.

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.
Piriformis muscle: clinical anatomy and consideration of the piriformis Syndrome
TLDR
The anatomical causes for the piriformis syndrome are rare and a more precise workup is necessary to rule out more common diagnosis.
Topographic variations of the relationship of the sciatic nerve and the piriformis muscle and its relevance to palsy after total hip arthroplasty
TLDR
According to the presented anatomical study, overstretching of the nerve itself or its branches in the area of the pelvitrochanteric muscles after their release from their origin can be another mechanism.
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.

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
This is a very rare case of surgically treated piriformis syndrome resulting from type d anatomic variation in Beaton’s classification.

TLDR
A tenotomy of the piriformis muscle at the greater trochanter relieved entrapment of the sciatic nerve and gave satisfactory results and a pelvic examination is recommended in the evaluation of suspected cases of piriformIS muscle syndrome.
