background: the principal aim of this study was therefore to investigate association between family history of osteo porotic hip fracture, bmd and femur geometry in bushehr city in south of iran. methods: in this cross-sectional study, data were obtained from iranian multi-center osteoporosis study (imos) in bushehr. healthy men and women aged 50 to 75 years were selected based on randomized cl...

Bilateral pedicle stress fractures are rare even in the elderly. Bilateral pedicle fractures are due to post-surgical complications at the level of fusion or stress related activities in most cases. The authors describe a unique case of adjacent L4 bilateral pedicle fractures, which developed 4 years after anterior lumbar interbody fusion with bone cement augmented screw fixation at the L5-S1 l...

OBJECTIVE To study the relationship of plasma homocysteine (Hcy), bone turnover biomarkers (BTB), and bone mineral density (BMD) with osteoporotic fracture (OPF) in elderly people. METHODS Eighty-two patients (aged 65 years or older) admitted to our orthopedics department between October 2014 and May 2015 were randomly divided into three groups: 1) OPF group: 39 cases with the mean age 81.82±...

This article is a comparative study. The aim of the study is to investigate the difference of sagittal alignment of the pelvis and spine between patients with thoracolumbar kyphosis secondary to ankylosing spondylitis (AS) and thoracolumbar fracture, and to evaluate the role of sacropelvic component in AS patients' adaption to the changes in sagittal alignment. Advanced stages of AS are often a...

Concomitant spine and hip disease in patients undergoing total hip arthroplasty (THA) presents a management challenge. Degenerative lumbar spine conditions are known to decrease lumbar lordosis and limit lumbar flexion and extension, leading to altered pelvic mechanics and increased demand for hip motion. In this study, the effect of lumbar spine disease on complications after primary THA was a...

1. Bone mineral content of the second, third and fourth lumbar vertebrae was determined in normal women and women with clinical osteoporosis by using dual-photon (153Gd) absorption. 2. A cross-sectional study of 70 normal (aged 19-88 years) showed a bone loss of 44% from the age of around 34 years throughout life. 3. Longitudinal data from 59 normal women confirmed that the vertebral bone loss ...

For comminuted shaft fracture of clavicle, the operative goal, aside from sound bone healing without complications of direct reduction, is maintenance of the original length in order to maintain the normal biomechanics of adjacent joint. Our bridge plating technique utilizing distraction through a lumbar spreader was expected to be effective for restoring clavicular length with soft tissue pres...

Introduction: Standard techniques for lumbar pedicle screw and rod fi xation involve open exposure and extensive muscle dissection. Percutaneous pedicle screw system minimises the morbidity associated with traditional open approaches without compromising the quality of spinal fi xation. A preliminary experience with this device has been encouraging. The purpose of this study was to demontrate o...
