Imaging on the painful and compressed nerve: lower extremity.
Int Orthop
January 2025
Aspetar Orthopedic and Sports Medicine Hospital, Doha, Qatar.
Entrapment neuropathies of the lower extremity are often underdiagnosed due to limitations in clinical examination and electrophysiological testing. Advanced imaging techniques, particularly MR neurography and high-resolution ultrasonography (US), have significantly improved the evaluation and diagnosis of these conditions by enabling precise visualization of nerves and their surrounding anatomical structures. This review focuses on the imaging features of compressive neuropathies affecting the lumbosacral plexus and its branches, including the femoral, obturator, sciatic, common peroneal, and tibial nerves.

Background: Piriformis syndrome, an often-overlooked cause of sciatica, commonly presents as chronic gluteal pain and poses a diagnostic challenge, particularly in patients with axial spondyloarthritis (axSpA).
Purpose: To examine piriformis muscle abnormalities on sacroiliac magnetic resonance imaging (MRI) and their association with clinical outcomes in patients with axSpA.
Material And Methods: This cross-sectional study included 100 axSpA patients (50 radiographic [r-axSpA], 50 non-radiographic [nr-axSpA]), classified by the 2009 ASAS Axial Spondyloarthritis criteria, who underwent MRI evaluations of the sacroiliac joints over a 6-month period.
Assessment of the piriformis muscle and piriformis syndrome via Web of Science database: A bibliometric analysis.

Background: Piriformis syndrome, which is seen as the cause of 0.3% to 6% of low back pain, is a painful condition that occurs as a result of compression of the piriformis muscle on the sciatic nerve. Although there are many studies in the literature about piriformis syndrome, no bibliometric analysis has been found.

Piriformis syndrome (PS) is an underdiagnosed condition, caused by entrapment of the sciatic nerve by the piriformis muscle tendon and adhesions in the deep gluteal space. We present a step-by-step endoscopic technique with the patient in a prone position through a posterior approach. This approach provides improved orientation for tracking the sciatic nerve from distal to proximal, facilitating the release of all adhesions and concluding with a piriformis tendon release.

Objective: To determine the prevalence of piriformis syndrome (PS) among undergraduate university health sciences students aged 18 to 25 and assess the significant predictors of PS regardless of its type and severe PS in particular.
Design: A cross-sectional study.
Setting: The study was conducted at a tertiary care hospital of a public university in Pakistan from December 2023 to May 2024.
