An appraisal and comparative analysis of superb microvascular imaging with conventional ultrasound and MRI for greater trochanteric pain syndrome management.

Greater trochanteric pain syndrome (GTPS) is a common cause of hip pain and is often associated with chronic lower back pain and lower extremity osteoarthritis. Its diagnosis is clinical; however, imaging has been shown to aid in the differential diagnosis of challenging cases. Superb microvascular imaging (SMI) is a new technique that may be more effective than power Doppler ultrasonography (PDUS) in the detection of inflammation-related vascularity in patients.

An unusual imaging finding mimicking double contour sign following ultrasound-guided intra-articular knee injection of steroid: A case report.

Examination of monosodium urate crystals in the synovial fluid remains the gold standard for the diagnosis of gout. On ultra-sound (US) examination, the double contour sign (DCS) is one of the most common imaging findings of gout. In this article, we present, for the first time, a unique imaging finding mimicking DCS after US-guided intra-articular knee injection of steroid and discuss it in light of the literature data.

The frequency of superior cluneal nerve entrapment diagnosed with ultrasound-guided nerve block in patients with low back pain: A prospective, cross-sectional study.

Introduction: To determine the frequency of superior cluneal nerve entrapment (SCN-E) in patients who applied to our outpatient clinic with low back pain.

Methods: Two hundred patients with mechanical low back pain persisting more than 3 months were included in our study. All patients were evaluated with detailed clinical history and physical examination.

Quadriceps femoris muscle ultrasound in sarcoidosis: an observational case-control study.

Background: Although loss of muscle mass may be associated with general weakness, intolerance to physical activity and fatigue, it is underestimated and poorly understood in patients with sarcoidosis.

Aim: To compare the quadriceps femoris muscle (QFM) thickness measured by ultrasonography (US) between the female patients with sarcoidosis and controls, secondly to assess the correlation between the muscle strength, fatigue and QFM thickness.

Design: Observational, case-control study.

Clinical and ultrasonographic enthesitis assessment before and after anti-tumor necrosis factor treatment in patients with spondyloarthritis.

Objectives: This study aimed to clinically and ultrasonographically evaluate enthesitis in patients with spondyloarthritis (SpA) and to determine enthesitis response to anti-tumor necrosis factor (TNF) treatment.

Patients And Methods: Thirty-one SpA patients (22 males, 9 females; mean age: 39.4±10.

Ultrasonographic evaluation of ulnar nerve morphology in patients with ulnar nerve instability.

Introduction/aims: Ulnar nerve instability (UNI) in the retroepicondylar groove is described as nerve subluxation or dislocation. In this study, considering that instability may cause chronic ulnar nerve damage by increasing the friction risk, we aimed to examine the effects of UNI on nerve morphology ultrasonographically.

Methods: Asymptomatic patients with clinical suspicion of UNI were referred for further clinical and ultrasonographic examination.

Ultrasonographic Evaluation of Nail Involvement in Patients With Axial Spondyloarthritis.

Objectives: This study aimed to evaluate the nail units of patients with axial spondyloarthritis (ax-SpA) using ultrasound and to identify any subclinical changes. We also aimed to examine the relationship between clinical enthesitis scores and nail involvement in patients with ax-SpA.

Methods: The study included 40 patients with ax-Spa, 40 patients with psoriatic arthritis (PsA), and 40 healthy controls.

Magnetic resonance imaging/ultrasound fusion-guided sacroiliac joint corticosteroid injection in patients with axial spondyloarthritis.

Local glucocorticoid injections are used in the treatment of isolated sacroiliitis in patients with spondyloarthritis. Sacroiliac joint injections can be performed intraarticularly or periarticularly. Since the accuracy of blind injections is low, fluoroscopy, magnetic resonance imaging, computed tomography, or ultrasonography guidance are used to increase the accuracy of sacroiliac joint injections.

Ultrasound-Guided Treatment of Meralgia Paresthetica: With or Without Corticosteroid? A Double-Blinded, Randomized Controlled Study.

Background: Blockade of the lateral femoral cutaneous nerve (LFCN) with local anesthetic (LA) has therapeutic role as well as diagnostic value for meralgia paresthetica (MP). The aim of this study was to compare the effectiveness of ultrasound-guided LA and LA + CS injections in the treatment of MP.

Methods: This was a prospective, double-blinded, randomized controlled study.

Ultrasound-guided lateral branch radiofrequency ablation for sacroiliac joint pain.

Sacroiliac joint (SIJ) pain is one of the leading causes of mechanical low back pain. Treatment includes conservative methods, surgery, and radiofrequency thermocoagulation (RFTC) as a novel therapeutic approach. Herein, we present a 71-year-old female patient who was first admitted to the outpatient clinic about four years ago.

An unusual cause of posterior interosseous nerve palsy and contribution of ultrasonography to electromyography in a patient with neurofibroma.

Neurofibroma, a benign peripheral nerve sheath tumor, represents a rare cause of posterior interosseous nerve syndrome. Electrodiagnostic studies may not identify the exact site of nerve compression, a possible lesion that compresses the nerve and do not provide information about the morphological changes. Ultrasound is a cost-effective, practical modality that provides the opportunity for dynamic tracking in the peripheral nerves, and it is widely considered as the initial imaging modality for peripheral nerves.

Coccydynia in patients with axial spondyloarthritis: Reflection of enthesitis?

Objectives: In this study, we aimed to compare the Maastricht Ankylosing Spondylitis Enthesitis Score (MASES) values of patients with axial spondyloarthritis (ax-SpA) with and without coccydynia.

Methods: We included 42 cases between the ages of 18 to 65 that were admitted to our clinic between August 1, 2019 and April 20, 2020 with the diagnosis of ax-SpA. The first group consisted of 13 patients with coccydynia and the second group consisted of 29 patients without coccydynia.

Bilateral foot drop after COVID-19-related acute respiratory distress syndrome: A case report.

In these days of the pandemic, we have faced with the locomotor system problems following severe acute respiratory syndrome-coro- navirus 2 (SARS-CoV-2) infection. While some of these problems are related to the disease itself, some of them are associated with the prolonged immobilization during the infection. Long-term intensive care unit admissions of patients may also lead to various types of neuropathies, extending the recovery period.

The lumbar erector spinae plane block: a cadaveric study.

Background: The aim of this cadaveric study was to investigate the erector spinae plane block (ESPB) in lumbar region and to elucidate the possible mechanisms of action of these injections in lumbar radicular pain by means of detecting expected dye dispersion to the neural structures.

Methods: Ultrasound-guided lumbar ESPB was performed in three formaldehyde-embalmed human cadavers. For this purpose, a 10 mL of methylene blue was injected into the fascial space between the L4 transverse process and the erector spinae muscles.
