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

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

Background: With the patient in a constant supine position, elevation of the femur in THA (DAA) provides a more intuitive and conducive location of the acetabulum for the correct placement of the acetabular prosthesis, but elevation of the femur for broaching becomes more challenging. The purpose of this study is to analyze the restriction of the ischiofemoral ligament and short external rotation muscles, and its effect on the elevation of the proximal femur in the DAA.
Methods: The study subjects comprised 5 freshly frozen cadavers with 10 normal hips. Read More

Background: Despite the popularity of minimally invasive approaches in total hip arthroplasty, studies regarding their impact on soft tissues and long-term benefits are lacking. This study aims to compare the 10-year functional outcome of the piriformis-sparing minimally invasive approach to the standard posterior approach for total hip arthroplasty surgery.
Methods: Hundred patients were randomized, 48 patients to the piriformis-sparing approach and 52 to the standard approach. Read More

Background: Sacral chordoma is a locally aggressive malignant tumour originating from ectopic notochordal cells. The natural history of sacral chordoma is a slow growing tumour arising at the midline of the lower sacrum that can invade the sacrum and progressively increase in size expanding cranially and anteriorly. Metastasis is very rare even when the tumour is large. Read More

Introduction: The piriformis muscle is clinically implicated in pain disorders, posterior approaches for total hip arthroplasty, and iatrogenic injury to the muscle and the surrounding nerves. The piriformis muscle has been said to receive innervation from L5 to S3 ventral rami with most sources using S1 and S2 ventral rami as the most common innervation this muscle. However, descriptions of the nerve in the literature are vague. Read More

Robinson, in 1947 introduced for the first time the term 'piriformis syndrome'. More recently, many etiologies of sciatic nerve entrapment around the gluteal region or the non-discogenic area have been identified, resulting in the use of a new term 'The Deep Gluteal Syndrome'. The purpose of this study was to assess the outcomes following the endoscopic release of sciatic nerve entrapment. Read More

Variants of gluteal neural anatomy are important to consider, especially during surgical approaches to the hip. During the routine dissection of the gluteal region, a variant of the sciatic nerve was found where the nerve left the pelvis fully split into its tibial and common fibular components. Intrapelvically and extrapelvically, there was no splitting of the two components by the piriformis muscle. Read More

Background And Purpose: The incidence of running related injuries remains high despite numerous efforts to understand the mechanical contributors to the etiology of these injuries. In light of continued running injury, theories of neuromuscular control, or movement patterns, have been suggested as possible contributors to running related injuries. However, the clinical decision making determining when altered neuromuscular control strategies may be affecting a runner's symptoms has not been described. Read More

Regardless of the surgical approach used, dislocation remains a complication following total hip replacement. In recent years, newer technologies, such as the use of large femoral heads, have reduced the rate of postoperative dislocation. The combination of such technology, together with a soft tissue repair technique, may reduce the dislocation rate even further. Read More

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

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.

Background: Endoscopic piriformis release (EPR) is among the available treatments for piriformis syndrome. This procedure typically involves dividing the muscle near the sciatic nerve in the sub-gluteal space, which contains numerous blood vessels and nerves. The objectives of this prospective cadaver study were: 1) to assess the reproducibility and quality of endoscopic piriformis tenotomy near the greater trochanter; 2) to detect iatrogenic injuries to the lateral hip rotators, nerves, and vessels; 3) and to define the surgical safety margins relative to the sciatic nerve and inferior gluteal bundle.

Purpose: The preservation technique of the piriformis tendon during the posterolateral approach in total hip arthroplasty (THA) is reportedly superior to the reattachment technique in terms of dislocation. However, the long-term effects of preservation of the piriformis tendon during THA remain unknown. In this study, we evaluated the contiguity of the piriformis/conjoined tendon and atrophy of the piriformis/internal obturator muscle during a long-term postoperative follow-up using magnetic resonance imaging (MRI).

Piriformis syndrome is a common cause of lumbar, gluteal, and thigh pain, frequently associated with sciatic nerve symptoms. Potential etiologies include muscle injury or chronic muscle stretching associated with gait disturbances. There is a common pathological end pathway involving hypertrophy, spasm, contracture, inflammation, and scarring of the piriformis muscle, leading to impingement of the sciatic nerve. Read More

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

Anterior cruciate ligament (ACL) injuries are a burdensome condition due to potential surgical requirements and increased risk of long term debilitation. Previous studies indicate that muscle forces play an important role in the development of ligamentous loading, yet these studies have typically used cadaveric models considering only the knee-spanning quadriceps, hamstrings and gastrocnemius muscle groups. Using a musculoskeletal modelling approach, we investigated how lower-limb muscles produce and oppose key tibiofemoral reaction forces and moments during the weight acceptance phase of unanticipated sidestep cutting.
