Deep gluteal syndrome as a cause of posterior hip pain and sciatica-like pain.

Bone Joint J 2020 May;102-B(5):556-567

Department of Orthopedic Surgery, Seoul National University Bundang Hospital, Department of Orthopedic Surgery, Seoul National University College of Medicine Seongnam, South Korea.

Deep gluteal syndrome is an increasingly recognized disease entity, caused by compression of the sciatic or pudendal nerve due to non-discogenic pelvic lesions. It includes the piriformis syndrome, the gemelli-obturator internus syndrome, the ischiofemoral impingement syndrome, and the proximal hamstring syndrome. The concept of the deep gluteal syndrome extends our understanding of posterior hip pain due to nerve entrapment beyond the traditional model of the piriformis syndrome. Read More

Case report and review of the potential role of the Type A piriformis muscle in dynamic sciatic nerve entrapment variant of piriformis syndrome.

Surg Radiol Anat 2020 Feb 28. Epub 2020 Feb 28.

Medical Department, Fremantle Football Club, Cockburn Central, WA, Australia.

Piriformis syndrome (PS) is an underdiagnosed but common cause of chronic buttock pain and sciatica. Anatomical variants of the piriformis muscle and sciatic nerve have not been thought to be significant in the pathophysiology of PS however, recent description of the piriformis musculotendinous junction has identified a common variant that we believe frequently results in dynamic sciatic nerve entrapment at the infra-piriformis fossa. We performed ultrasound guided low-dose Botulinum Toxin-A (BTX-A) injection to the lower piriformis muscle belly in an elite Australian Rules football player with PS and Type A piriformis muscle to relieve symptomatic sciatic nerve compression.

Radiographics 2020 Jan-Feb;40(1):181-199. Epub 2019 Nov 22.

From the Department of Radiology, University of British Columbia, Royal Columbian Hospital, 300 Columbia St E, New Westminster, BC, Canada V3L 3W7 (J.I.B.); Department of Radiology and Imaging Sciences, University of Utah School of Medicine, Salt Lake City, Utah (B.Y.C.); and Department of Radiology, University of Wisconsin School of Medicine and Public Health, Madison, Wis (P.M., K.S.L.).

Hip pain is a commonly reported primary symptom with many potential causes. The causal entity can remain elusive, even after clinical history review, physical examination, and diagnostic imaging. Although there are many options for definitive treatment, many of these procedures are invasive, are associated with risk of morbidity, and can be unsuccessful, with lengthy revision surgery required.

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

Department of Physical Medicine and Rehabilitation, Istanbul University, Cerrahpasa Medical Faculty, Istanbul, Turkey.

Key Points: • Lack of use of local injection test to confirm the diagnosis may lead to miss the diagnosis of PMS of myofascial origin. • Piriformis muscle syndrome should be diagnosed on the basis of clinical symptoms, specific physical examinations, and positive response to local injection. • Sciatic nerve entrapment is not a must in the diagnosis of PMS and PMS is mostly myofascial in origin.

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

Sciatic neuropathy developed after injection during curettage.

Agri 2016 Jan;28(1):46-8

Department of Neurology, Istanbul University Cerrahpasa Faculty of Medicine, Istanbul, Turkey.

Intramuscular injections are likely the most common cause of sciatic nerve injury in developing countries. Less common causes include piriformis syndrome, primary tumors of the sciatic nerve, metastatic tumors invading or compressing the nerve, endometriosis, vascular malformations, and prolonged immobilization or positioning. While the most reliable diagnostic and prognostic methods include nerve conduction studies and electromyography, magnetic resonance imaging has been suggested as an alternative method of determining type of lesion, establishing location, and investigating level of nerve involvement.

Evaluation and management of ischiofemoral impingement: a pathophysiologic, radiologic, and therapeutic approach to a complex diagnosis.

Skeletal Radiol 2016 Jun 3;45(6):771-87. Epub 2016 Mar 3.

Department of Radiology, POVISA Hospital, Vigo, Pontevedra, Spain.

Ischiofemoral impingement syndrome (IFI) is an underrecognized form of atypical, extra-articular hip impingement defined by hip pain related to narrowing of the space between the ischial tuberosity and the femur. The etiology of IFI is multifactorial and potential sources of ischiofemoral engagement include anatomic variants of the proximal femur or pelvis, functional disorders as hip instability, pelvic/spinal instability, or abductor/adductor imbalance, ischial tuberosity enthesopathies, trauma/overuse or extreme hip motion, iatrogenic conditions, tumors and other pathologies. Magnetic resonance imaging (MRI) is the diagnostic procedure of choice for assessing IFI and may substantially influence patient management. Read More

Endoscopic Sciatic Neurolysis.

Arthrosc Tech 2015 Aug 10;4(4):e353-8. Epub 2015 Aug 10.

Millennium Institute of Sport and Health, Auckland, New Zealand.

Despite remaining a controversial diagnosis, piriformis syndrome continues to affect patients' quality of life with pain, sitting discomfort, and exercise intolerance. Open sciatic neurolysis has been noted by the senior author to often only bring temporary relief of the symptoms, with the recurrence presumably due to postoperative scar tissue. Minimally invasive techniques used to decompress the nerve have met with mixed results. Read More

Injuries to the hip and pelvis among runners can be among the most challenging to treat. Advances in the understanding of running biomechanics as it pertains to the lumbopelvic and hip regions have improved the management of these conditions. Conservative management with an emphasis on activity modification and neuromuscular exercises should comprise the initial plan of care, with injection therapies used in a supportive manner.

Usefulness of Magnetic Resonance Neurography for Diagnosis of Piriformis Muscle Syndrome and Verification of the Effect After Botulinum Toxin Type A Injection: Two Cases.

Medicine (Baltimore) 2015 Sep;94(38):e1504

From the Department of Rehabilitation Medicine, Veterans Health Service Medical Center, Department of Rehabilitation Medicine, Seoul, Korea (HEY); Department of Rehabilitation Medicine, Gangnam Severance Hospital, Rehabilitation Institute of Neuromuscular Disease, Yonsei University College of Medicine, Seoul, Korea (JHP); and Department of Radiology, Gangnam Severance Hospital, Yonsei University College of Medicine, Seoul, Korea (SJK).

Piriformis muscle syndrome (PMS) is a controversial neuromuscular disorder that is presumed to involve compression neuropathy of the sciatic nerve at the level of the piriformis muscle. Botulinum toxin A (BTX-A) injection into the piriformis muscle is widely used as a treatment aimed at relieving sciatic nerve compression. In 2 patients with PMS, magnetic resonance neurography (MRN) was taken before and after BTX-A injection. Read More

Ultrasound-Guided Injection of Botulinum Toxin Type A for Piriformis Muscle Syndrome: A Case Report and Review of the Literature.

Toxins (Basel) 2015 Aug 10;7(8):3045-56. Epub 2015 Aug 10.

Physical Medicine and Rehabilitation Section, "OORR" Hospital, University of Foggia, Foggia 71100, Italy.

Piriformis muscle syndrome (PMS) is caused by prolonged or excessive contraction of the piriformis muscle associated with pain in the buttocks, hips, and lower limbs because of the close proximity to the sciatic nerve. Botulinum toxin type A (BoNT-A) reduces muscle hypertonia as well as muscle contracture and pain inhibiting substance P release and other inflammatory factors. BoNT-A injection technique is important considering the difficult access of the needle for deep location, the small size of the muscle, and the proximity to neurovascular structures. Read More

Piriformis syndrome: comparison of the effectiveness of local anesthetic and corticosteroid injections: a double-blinded, randomized controlled study.

Pain Physician 2015 Mar-Apr;18(2):163-71

Department of Physical Medicine and Rehabilitation, Koc University Hospital, Istanbul, Turkey; Istanbul University, Cerrahpasa Medical Faculty, Istanbul, Turkey;3Medical Park Hospital Gebze, Kocaeli, Turkey; Medicana Hospital Haznedar, Istanbul, Turkey.

Background: Piriformis syndrome (PS), which is characterized by pain radiating to the gluteal region and posterior leg, is accepted as one of the causes of sciatalgia. Although the importance of local piriformis muscle injections whenever PS is clinically suspected has been shown in many studies, there are not enough studies considering the clinical efficacy of these injections.

Objective: To investigate the differences between local anesthetic (LA) and LA + corticosteroid (CS) injections in the treatment of PS. Read More
