Abstract An uncomon cause of sciatica is piriformis syndrome, that involves deep buttock pain reffered to the leg. Piriformis syndrome is usually discribed as a neuromuscular disorder caused by compression or irritation of the sciatic nerve by the piriformis muscle. There are a lot of means to diagnose Piriformis syndrome, and to distinguish it from other pain inducing conditions. Unfortunatelly not every practitioner has the opportunity to use special means, and not every patient has the financial support to beneficiate of the same special means, represented by Computed tomography (CT), Magnetic resonance imaging (MRI), Electromyography (EMG) and Neurography. For this reason, the present paper gathered the most popular functional tests used in the practice to diagnose the piriformis syndrome

Summary Objectives: Although magnetic resonance imaging (MRI) is reported to be superior to myelography to determine the location and site of first time disc herniation, comparison of these diagnostic methods in cases of recurrent intervertebral disc disease (IVD) herniation after a first surgery has not been evaluated. The objective was to compare the diagnostic accuracy of MRI and myelography in a series of dogs undergoing repeat surgical decompression for recurrent IVD extrusion when compared to the gold standard of surgery. Methods: Ten dogs with recurrent IVD herniation underwent MRI and myelography followed by surgical decompression. Three observers reviewed the images to determine the site and side of the first surgery and the recurrent lesion. Agreement was determined by calculating a kappa (κ) score. Results: Substantial interobserver agreement was noted for recurrent lesion site using MRI and myelography (κ = 0.77 vs. 0.73) and when comparing MRI and myelography to the reported surgical site (κ = 0.73 vs. 0.67). Interobserver agreement was greater with MRI for circumferential location compared to myelography (κ = 0.76 vs. 0.43), similar to what was found when comparing to surgical side (κ = 0.82 vs. 0.49). The previous surgical site in this study had no effect on ability to identify the new lesion. Clinical significance: Despite the limitations of MRI, there was greater agreement between observers using MRI for both the recurrent and first lesion.

The spondyloarthritides encompass various clinical manifestations. The hallmark of the spondyloarthropathies is inflammatory axial and sacroiliac (buttock) pain. Associated findings include peripheral arthritis, uveitis, conjunctivitis, enthesitis, and psoriasis. Human leukocyte antigen (HLA) B27 is positive in a majority of patients. Radiographic abnormalities appear first on vertebral column/sacroiliac magnetic resonance imaging (MRI) and many years later on radiography, which makes the diagnosis challenging. Of course, rheumatoid factor is negative – hence the term seronegative arthritis. Other clinical clues that help identify this disease’s spectrum are a family history of ankylosing spondylitis (AS), psoriasis, or inflammatory bowel disease (IBD); intestinal or genitourinary symptoms; or the presence of psoriasis. All this heterogeneity makes an early diagnosis difficult.

Title: The Effectiveness of Myofascial Release over Stretching on Pain and Range of Motion among Female College Students with Piriformis Syndrome.Background & Aim: Piriformis syndrome is a painful neuromuscular disorder that occurs when the piriformis muscle irritates and/or compresses the proximal sciatic nerve. Prolonged sitting position is the foremost cause of piriformis tightness in sedentary population that may eventually leads to piriformis syndrome. The incidence of piriformis has been reported to be six times more prevalent in female than in males. Piriformis tightness will cause reduced in range of motion as well as limitations in walking, sitting and even running. Moreover, individuals will also feel pain at their butt muscles which could be frustrating. Thus, the aim of this study is to determine the effectiveness of myofascial release over stretching on pain and range of motion among female college students with piriformis syndrome.Methods: twenty subjects aged between 19 to 25 years old with tight piriformis muscle for 4 weeks will make a part of the study based on the inclusion and exclusion criteria. Subjects are divided and will undergo myofascial release and stretching treatment for 4 weeks twice in a week. At the beginning before the session the pain score and goniometer measurements will be recorded.Conclusion: Group 1 and Group 2 are beneficial in reducing pain and range of motion. Therefore, there are no significant effect of myofascial release over stretching between the two groups.Keywords: Myofascial release, college students, piriformis syndrome, stretching, goniometer, pain score.

Background: Piriformis syndrome (PS) is a neuromuscular condition caused by the entrapment of the sciatic nerve at the level of the piriformis muscle (PM). Diagnosing PS remains challenging despite recent invasive and non-invasive diagnostic methods. Response to invasive nerve block is still one of the most reliable diagnostic modalities because there is no gold standard test for PS. As early diagnosis may prevent delayed diagnosis that results in chronic somatic dysfunction and muscle weakness, a screening test with high sensitivity could guide clinicians in performing the next appropriate step in diagnosing PS.Aim: The purpose of this study is to determine the sensitivity, specificity, and best cut-off point of ultrasound-guided PM thickness in PS.Method: This case-control study was conducted in a general hospital in Tangerang during a 3-month period. We recruited 58 patients clinically diagnosed with PS and 58 healthy patients (without a history of hip and buttock pain) during their visits to the outpatient clinic. All patients underwent ultrasound assessment to measure bilateral PM thickness. Sex, age, body mass index, history of micro-/macro-trauma, and prolonged sitting duration were recorded. Statistical analyses were performed using the Statistical Package for the Social Sciences version 25.Result: The PS and control groups predominantly comprised female subjects, with mean ages of 51.79 ± 14.10 and 50.09 ± 13.26 years on PS and healthy subjects, respectively. The mean ultrasound-guided PM thickness was higher in PS subjects compared to healthy subjects with mean thicknesses of 1.16 ± 0.13 and 0.85 ± 0.11 cm, respectively (p < 0.05). The area under the receiver operating characteristic curve of the PM was 0.970 (95% confidence interval 0.943–0.998, p < 0.05). The best cut-off point defined by Youden's J index was 0.9950 cm for all PS subjects.Conclusion: We propose 0.9950 cm as the cut-off point for diagnosing PS by ultrasound, which has the sensitivity and specificity of 94.8 and 87.9%, respectively.

Repetitive mechanical loading induces microscale damage in bone to accumulate and may lead to stress fractures [1]. People with weakened bones due to disuse or disease, or, healthy people who have excessive exercise regimes (soldiers and athletes) experience these fractures [2]. Stress fractures interrupt training, reduce fitness and may even lead to discharge from the military in certain occasions [3]. Therefore, early prognosis and prevention of stress fractures would be desirable. Currently, following methods are being used for diagnosis: plain radiography, computed tomography (CT), bone scintigraphy and magnetic resonance imaging (MRI). The sensitivity of plain radiography is very low, 15–35% [4]. CT is less sensitive than radiography except some very special and rare cases of stress fractures [5]. Among these diagnostic methods, scintigraphy and MRI are more sensitive. However, the former lacks specificity because it may confound infections, tumors, bone infarctions, periostisis and osteonecrosis [2,5]. Furthermore, it is radioactive [5]. MRI has immense economical and logistical limitations [6].

Piriformis Syndrome (PS) is an uncommon, controversial neuromuscular disorder that is presumed to be a compression neuropathy of the sciatic nerve at the level of the piriformis muscle (PM). The diagnosis is hampered by a lack of agreed upon clinical criteria and a lack of definitive investigations such as imaging or electrodiagnostic testing. Treatment has focused on stretching, physical therapies, local injections, including botulinum toxin, and surgical management. This article explores the various sources of controversy surrounding piriformis syndrome including diagnosis, investigation and management. We conclude with a proposal for diagnostic criteria which include signs and symptoms, imaging, and response to therapeutic injections.
