A 30-year-old Indian man presented with progressive renal impairment following a seizure. The complaint of troublesome back pain led to the suspicion of rhabdomyolysis being the cause of acute renal failure. The diagnosis of rhabdomyolysis was supported by a markedly elevated serum creatinine phosphokinase level. Magnetic resonance imaging revealed a right paraspinal muscle tear. The patient un...

STUDY DESIGN Retrospective case control study. OBJECTIVE To determine prevalence and risk factors for intraoperative bacterial contamination in posterior spinal deformity surgery. SUMMARY OF BACKGROUND DATA The prevalence of deep surgical site infection in pediatric spinal deformity surgery varies from 1% to 14%. Little evidence exists about the incidence and role of intraoperative bacteria...

Low-Back Disorders (LBDs) are the most prevalent source of musculoskeletal disability and the most common musculoskeletal problem in the United States. LBDs are often attributed to tissue strain from spinal instability. Stability is defined as the ability to maintain intervertebral and global torso equilibrium despite the presence of small mechanical disturbances and/or small neuromuscular cont...

Methods To measure the muscle activations of the C6, T7 and L5 paraspinal muscles and lumbar multifidus during standing, EMG (Keypoint, Medrtonic, USA) was used. After breathing was calmed down, muscle activation during standing on the ground with bare foot was measured. Subsequently, muscle activation during standing wearing shoes with 8cm Wedge heel, Setback heel and French heel were measured...

A 67-year-old man with poorly controlled type II diabetes mellitus was evaluated for right lower extremity erythema and swelling and left-sided lower back pain. He was found to have Pasteurella multocida bacteremia; magnetic resonance imaging showed osteomyelitis of the lumbar spine with myositis in the adjacent left paraspinal muscles. He was initially treated with intravenous antibiotics and ...

A 9-year-old female child presented with a history of falls, weight loss, diffuse leg pain, and progressive gait disorder, following 1 previous event described as a tonic–clonic seizure. She had increased thyroid volume, brisk symmetric reflexes, abnormal gait, and painful spasms of the paraspinal musculature. Thyroid function tests indicated biochemical hyperthyroidism, and thyrotropin recepto...

Electrodiagnostic findings of fibrillations and positive sharp waves in the lumbosacral paraspinals in patients without previous back surgery has been generally considered to be abnormal, consistent with posterior rami denervation. In some cases, it is the only abnormality on the electromyographic examination. This study was undertaken to determine the prevalence of abnormal spontaneous activit...

INTRODUCTION Camptocormia refers to an abnormal posture with flexion of the thoraco-lumbar spine which increases during walking and resolves in supine position. This symptom is an increasingly recognized feature of parkinsonian and dystonic disorders, but may also be caused by neuromuscular diseases. There is recent evidence that both central and peripheral mechanisms may be involved in the pat...

Muscle signal alteration detected on MRI is seen in diverse pathologic conditions. We observed signal alterations within the paraspinal muscles in dogs with acute thoracolumbar intervertebral disk extrusion. The aim of this retrospective study was to describe MRI features of paraspinal muscle signal alteration in dogs with acute thoracolumbar intervertebral disk extrusion and to investigate an ...

A 31-year-old female with a history of ovarian cancer underwent an F-18 fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET-CT) scan. The PET-CT demonstrated focal nodular uptake in the subcutaneous tissue of the back adjacent to the paraspinal muscles. Color Doppler ultrasonography examination demonstrated a vascular solid mass. The patient underwent biopsy followed ...
