Some cases with lumbar degenerative diseases require multi-level fusion surgeries. At our institute, 27 and 4 procedures of 3- and 4-level fusion were performed out of a total 672 posterior lumbar interfusions (PLIFs) on patients with lumbar degenerative disease from 2005 to 2010. We present 2 osteoporotic patients who developed proximal vertebral body fracture after 4-level fusion. Both cases ...
AIM To carry out comparison and correlation analyses of the intervertebral disc (IVD) and vertebral body (VB) volumes in magnetic resonance (MR) images of patients with degenerated and nondegenerated lumbar discs. MATERIALS AND METHODS MR images were examined retrospectively in 93 patients. Lumbar VB and IVD volumes in T1-T2 weighted sagittal MR images were calculated via the Cavalieri method...
Introduction: Bone mineral density (BMD) has been identified as a major factor in spine construct strength, with failures resulting in pedicle screw loosening and pullout [2,3]. Computed tomography (CT) scans have been shown to effectively measure BMD [1,4]. Previous research has utilized this linear correlation of CT Hounsfield Units (HU) to BMD in order to determine BMD as a function of anato...
How are spinopelvic tumor resections classified? The type of pelvic resection depends on the area involved and the extent of the tumor. Problems arise when the tumor involves the sacrum and the lower lumbar spine. To obtain acceptable surgical margins in these cases, skeletal resection should extend beyond the standard hemipelvectomy (ie, the sacroiliac joint) and may include the ilium, part of...
An extradural spinal tumor was diagnosed in a 12-year-old Labrador retriever that was presented with a one-week history of paraparesis. Myelography indicated a deviation of the spinal cord to the right side at the level of the second lumbar (L2) vertebra. The difference in length measuring the left and right sides of the L2 vertebra suggested a fracture of the vertebral body. Severe bone remode...
Human lumbar vertebrae support the weight of the upper body. Loads lifted and carried by the upper extremities cause significant loading stress to the vertebral bodies. It is well established that trauma-induced vertebral fractures are common especially among elderly people. The aim of this study was to investigate the morphological factors that could have affected the prevalence of trauma-rela...
Abstract: Menopausal women have many problems such as osteoporosis that means decrease in bone density. One of the solutions for prevent this problem is doing exercises. Study the effect of 16 weeks Pilates training on bone density in menopausal women is the purpose of present study. The subjects of this study were 30 menopausal women that divided to two groups randomly. T-score of L1-L4 of ve...
[Purpose] The purpose of this case study was to identify the effects of joint mobilization using Kaltenborn-Evjenth orthopedic manual therapy (KEOMT) and proprioceptive neuromuscular facilitation (PNF) techniques on a patient with chronic low back pain (CLBP) and a lumbar transitional vertebra. [Methods] The intervention methods were joint mobilization using KEOMT and PNF techniques. The progra...
Objective To assess the cross-sectional area (CSA) of the muscles for investigating the occurrence of asymmetry of the paraspinal (multifidus and erector spinae) and psoas muscles and its relation to the chronicity of unilateral lumbar radiculopathy using magnetic resonance imaging (MRI). Methods This retrospective study was conducted between January 2012 to December 2014. Sixty one patients ...
