Epidemiology and etiology of secondary piriformis syndrome: A single-institution retrospective study.

J Clin Neurosci 2019 Jan 24;59:209-212. Epub 2018 Oct 24.

Department of Neurological Surgery, University of Miami Miller School of Medicine, Miami, FL, USA. Electronic address:

Piriformis syndrome (PS) is a rare etiology of extra-spinal sciatica in which pathologies associated with or around the piriformis muscle (PM) irritate the adjacent sciatic nerve (SN), however, there is scarcity in the literature regarding its exact etiologies, thus, we performed a retrospective study to elucidate the epidemiology of PS and assess various causes of the syndrome. Our study included patients assessed at our institution who presented with sciatica of non-spinal origin between May 2014 and December 2015. Radiology reports of all patients who received pelvic MRI were examined for positive findings involving PM and SN. Read More

EMG in piriformis syndrome diagnosis: Reliability of peroneal H-reflex according to results obtained after surgery, Botox injection and medical treatment.

J Clin Neurosci 2019 Jan 28;59:55-61. Epub 2018 Nov 28.

Orthopedic Surgery Department, Sacré-Coeur Hospital, P.O. Box 116, Hazmieh, Lebanon.

Diagnosing piriformis syndrome (PS) throughout the past decades was not that easy, however peroneal H-reflex was proved as reliable test for PS with the change in wave amplitude and delay in conduction as parameters for diagnosis. We interpreted these parameters according to treatment's results carried out for patients presenting clinical PS, aiming to define a threshold value for peroneal H-reflex delay to accurately diagnose. A retrospective mono-centric review of 27 patients, 9 females and 18 males, aged 22-65 years, benefited from peroneal H-reflex test and treated for clinical PS. Read More

Authors:
Md Abu B Siddiq

Cureus 2018 May 10;10(5):e2606. Epub 2018 May 10.

Physical Medicine and Rheumatology, Brahmanbaria Medical College, Bangladesh.

Piriformis syndrome (PS) involves the piriformis muscle and adjacent sciatic nerve, producing features similar to true sciatica of lumbar spine origin, for example, lumbar disc prolapse, thereby confusing pain physicians about the diagnosis. Synonyms that are used frequently for PS are deep gluteal syndrome, extra-spinal sciatica, wallet neuritis, etc. Commonly presenting symptoms of PS include gluteal pain which increases with affected side sitting/per-rectal manoeuvre, and improves with ambulation/intra-lesional steroid, etc. Read More

Diagnosis and Management of Piriformis Syndrome: A Rare Anatomic Variant Analyzed by Magnetic Resonance Imaging.

J Clin Imaging Sci 2018 21;8. Epub 2018 Feb 21.

Department of Radiology, David Grant Medical Center, Fairfield, CA, USA.

Piriformis syndrome is an uncommon condition that causes significant pain in the posterior lower buttocks and leg due to entrapment of the sciatic nerve at the level of the piriformis muscle. In the typical anatomical presentation, the sciatic nerve exits directly ventral and inferior to the piriformis muscle and continues down the posterior leg. Several causes that have been linked to this condition include trauma, differences in leg length, hip arthroplasty, inflammation, neoplastic mass effect, and anatomic variations. Read More

Ultrasound Imaging and Guided Injection for the Lateral and Posterior Hip.

Am J Phys Med Rehabil 2018 04;97(4):285-291

From the Department of Physical Medicine and Rehabilitation, National Taiwan University Hospital, BeiHu Branch and National Taiwan University College of Medicine, Taipei, Taiwan (K-VC, W-TW); Department of Physical Medicine and Rehabilitation, School of Medicine, Virginia Commonwealth University, Richmond, Virginia (HLL); John A Burns School of Medicine, University of Hawaii at Manoa, Honolulu, Hawaii (HLL); and Department of Physical and Rehabilitation Medicine, Hacettepe University Medical School, Ankara, Turkey (LÖ).

Ultrasound has emerged as one of the most utilized tools to diagnose musculoskeletal disorders and to assist in interventions. Traditionally, sonographic examination of the hip joint has been challenging because most of the major structures are deeply situated, thus requiring the use of curvilinear transducer for better penetrance. The posterior lateral hip is a frequent area for musculoskeletal pain and nerve entrapments. Read More

Deep gluteal space problems: piriformis syndrome, ischiofemoral impingement and sciatic nerve release.

Muscles Ligaments Tendons J 2016 Jul-Sep;6(3):384-396. Epub 2016 Dec 21.

Orthopedic Surgery Department Clinica Mompia, Santander, Cantabria, Spain.

Background: Deep gluteal syndrome (DGS) is an underdiagnosed entity characterized by pain and/or dysesthesias in the buttock area, hip or posterior thigh and/or radicular pain due to a non-discogenic sciatic nerve entrapment in the subgluteal space. Multiple pathologies have been incorporated in this all-included "piriformis syndrome", a term that has nothing to do with the presence of fibrous bands, obturator internus/gemellus syndrome, quadratus femoris/ischiofemoral pathology, hamstring conditions, gluteal disorders and orthopedic causes.

Methods: This article describes the subgluteal space anatomy, reviews known and new etiologies of DGS, and assesses the role of the radiologist and orthopaedic surgeons in the diagnosis, treatment and postoperative evaluation of sciatic nerve entrapments. Read More

[Tendinopathies of the hip : Treatment recommendations according to evidence-based medicine].

Unfallchirurg 2017 Mar;120(3):192-198

Klinik für Unfallchirurgie, Medizinische Hochschule Hannover, Carl-Neuberg-Str. 1, 30625, Hannover, Deutschland.

Tendinopathies of the hip are a differential diagnostic challenge. The spatial proximity of these structures is challenging and many of the structures are located in very deep positions in an individual-specific manner and are covered by other tissues resulting in difficult accessibility for a clinical examination. Furthermore, the definition of the different syndromes is not consistent in the literature, which makes a comparability and assessment difficult. Read More
