Introduction. The association of bone morphogenetic protein 2 (BMP2) with BMD and risk of fracture was suggested by a recent linkage study, but subsequent studies have been contradictory. We report the results of a study of the relationship between BMP2 genotypes and BMD, annual change in BMD, and risk of fracture in male subjects. Materials and Methods. We tested three single-nucleotide polymo...

In a review of 155 craniovertebral fractures (occiput-C1-C2), 40 of these had associated fractures and/or dislocations or subluxations elsewhere in the spine. This rather common occurrence, one of four, has not been emphasized in the recent literature, indicating that the radiologic examination should not stop after the craniovertebral fracture is identified. Furthermore, in 13 patients, neurol...

Traumatic spondylolisthesis of the lumbar spine is uncommon and can result in canal narrowing and spinal cord injury. Early decompression promotes recovery of neurological function. We report 3 such cases: one in the lumbosacral joint and 2 in the lumbar spine. The former patient had an open fracture-dislocation and underwent (delayed) posterior decompression and instrumentation without interbo...

We report the first case of a combined bony and soft tissue Chance fracture in the thoracic spine, with late presenting displacement following conservative management. Chance fractures are flexion-distraction injuries to the spine. They consist of disruption and longitudinal separation of the posterior elements of the vertebra, with the fracture extending through the pedicles and into the verte...

STUDY DESIGN Prospective, randomised controlled, single centre study of 45 patients posted for two level lumbar fixation surgery in the prone position. PURPOSE To compare intra-abdominal pressure (IAP), mean airway pressure mean airway pressure and blood loss during the spine surgery in prone position using three different positioning systems. OVERVIEW OF LITERATURE Studies have correlated ...

Tension pneumocephalus occurs when a continuous flow of air accumulates in the intracranial cavity and produces a mass effect on the brain. We describe a case in which tension pneumocephalus was caused by the performance of continuous lumbar CSF drainage in a middle-aged man who had experienced a temporal bone fracture. Continuous lumbar CSF drainage is commonly performed in patients with tempo...

We experienced a 73-year-old male with lumbar nerve root compression due to leakage of bone cement after vertebroplasty. He was underwent vertebroplasty for acute osteoporotic L4 compression fracture at our hospital. After vertebroplasty, his back pain was improved but right leg pain was newly developed. Lumbar computed tomography scanning showed that bone cements were leaked along the L4 nerve...

[Purpose] To examine the variations in the lumbopelvic rhythm and lumbar-hip ratio in the frontal plane. [Subjects and Methods] Markers were placed on the T10 and T12 spinous processes, bilateral paravertebral muscles at the T11 level, the pelvis, and the femur. Lumbar spine and hip angles were measured during lateral trunk bending using three-dimensional motion analysis. Data from the trunk la...

[Purpose] The purpose of this study was to examine the effects of running in place while using the abdominal drawing-in method on healthy adults' lumbar stability. [Subjects] A total of 30 subjects were divided into a training group of 15 subjects and a control group of 15 subjects. [Methods] The training group ran in place using the abdominal drawing-in method for 30 minutes per session, three...

The aim of this study was to investigate joint mobility, segmental and general spinal mobility and their interrelationship in 607 women working as homecare personnel. Joint mobility (mainly peripheral) was estimated using the "Beighton" score. Spinal posture and mobility were measured by Debrunner's kyphometer. Passive segmental mobility and pain provocation were estimated manually. Reliability...
