OBJECTIVE Screw fixation via the paraspinal muscle sparing approach and by percutaneous screw fixation are known to diminish the risk of complications, such as, iatrogenic muscle injury as compared with the conventional midline approach. The purpose of this study was to evaluate tissue injury markers after these less traumatic screw fixation techniques for the treatment of L4-L5 spondylolisthes...

Recurrent low back pain (LBP) is a common musculoskeletal problem, and there is a 24% to 87% recurrence rate within one year [1,2]. Those who have recovered from an episode of LBP demonstrated altered paraspinal muscle spindle afference and central processing of this sensory input for balance performance [3-5], altered proprioceptive postural control that might be caused by anticipation of post...

OBJECTIVE To evaluate the changes in static and dynamic postural control after the development of acute low back pain. METHODS Thirty healthy right-handed volunteers were divided into three groups; the right back pain group, the left back pain group, and the control group. 0.5 mL of 5% hypertonic saline was injected into L4-5 paraspinal muscle for 5 seconds to cause muscle pain. The movement ...

Patients with primary orthostatic tremor (OT) experience a disabling sense of unsteadiness but rarely fall. In order to study the relationship between the development of subjective unsteadiness, objective unsteadiness and tremor, we recorded standing under four conditions (eyes open or closed, feet together or apart) in six patients with OT. Subjective unsteadiness was indicated by the patients...

Pisa Syndrome (PS) is a real clinical enigma, and its management remains a challenge. In order to improve the knowledge about resting state and during maximal voluntary muscle contraction (MVMC) of the axial muscles, we described the electromyography results of paraspinal muscles, rectus abdominis, external oblique, and quadratus lumborum of both sides of 60 patients. Electromyography was asses...

Background To determine the usefulness of enhanced rate gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid–enhanced magnetic resonance imaging (EOB-MRI) during hepatobiliary phase as a new parameter for hepatic functional reserve. Aim We retrospectively analyzed 153 patients who underwent EOB-MRI before radiofrequency ablation or resection between January 2008 and December 2012. The wa...

BACKGROUND Involutional changes to the body in elderly patients affect the shape of the spine and the activity of postural muscles. The purpose of this study was to assess the influence of age-related changes in spinal curvature on postural balance in elderly women. METHODS The study population consisted of 90 women, with a mean age of 70 ± 8.01 years. Static balance assessments were conducte...

BACKGROUND Child with mild scoliosis is always a subject of interest for most orthopaedic surgeons regarding progression. Literature described Hueter-Volkmann theory regarding disc and vertebral wedging, and muscular imbalance for the progression of adolescent idiopathic scoliosis. However, many authors reported spontaneous resolution of curves also without any reason for that and the rate of r...

AIM To investigate the effects of local and systemic administration of etanercept on the formation of epidural fibrosis. MATERIAL AND METHODS Twenty-eight rats were randomly divided into four equal groups (Control, SpongostanTM, Local etanercept and Systemic etanercept) and laminectomy was performed between T11 and L1 in all rats. SpongostanTM was soaked with saline (0.1 mg/kg), local etanerc...
