Low bone mineral density (BMD) is common in people living with HIV infection (PLWH), increasing fracture risk. Alcohol use is also common in PLWH and is a modifiable risk factor for both HIV disease progression and low BMD. In PLWH, alcohol's effect on BMD is not well understood.We studied adult PLWH with substance dependence. We measured lifetime alcohol use (kg) and recent (i.e., past 30-day) alcohol use (categorized as: abstinent, low risk, or high risk). In adjusted multivariable regression analyses, we tested associations between lifetime and recent alcohol use and (i) mean BMD (g/cm) at the femoral neck, total hip, and lumbar spine and (ii) low BMD diagnosis (i...

We describe the use of a C1 laminar screw in combination with a C2 laminar screw as a salvage technique to treat two patients, one with persistent first intersegmental artery and the other with vertebral artery occlusion after cervical spine fracture. The combined use of C1 and C2 laminar screws allows for good fixation of the atlantoaxial joint with a lower risk of vertebral artery injury; therefore, it can be an alternative surgical procedure for patients with congenital or traumatic anomalous vertebral artery...

PURPOSE: Bone fracture risk assessed ancillary to positron emission tomography with computed tomography co-registration (PET/CT) could provide substantial clinical value to oncology patients with elevated fracture risk without introducing additional radiation dose. The purpose of our study was to investigate the feasibility of obtaining valid measurements of bone mineral density (BMD) and finite element analysis-derived bone strength of the hip and spine using PET/CT examinations of prostate cancer patients by comparing against values obtained using routine multidetector-row computed tomography (MDCT) scans-as validated in previous studies-as a reference standard...

Post-pregnancy osteoporosis is a rare condition with little known pathophysiology. Most cases are diagnosed in the late stage of pregnancy or in the post-partum while breastfeeding, particularly in first pregnancy. Vertebral fractures are most commonly observed and characterized by prolonged severe pain and functional limitations. Measurements of bone mineral density(BMD)of the lumbar spine and proximal femur with dual energy X-ray absorptiometry(DXA)are the clinical methods most commonly used for no fracture women...

BACKGROUND: Ankylosing spondylitis (AS) is a chronic autoimmune spondyloarthropathy that primarily affects the axial spine and hips. Progressive disease leads to pronounced spinal kyphosis, positive sagittal balance, and altered biomechanics. The purpose of this study is to determine the complication profile of patients with AS undergoing total hip arthroplasty (THA). METHODS: The Medicare sample was searched from 2005 to 2012 yielding 1006 patients with AS who subsequently underwent THA...

BACKGROUND: The objective of surgical management of spinal metastases is to reduce pain and improve the patient's quality of life. The operation should restore spinal stability and decompress neural structures. One surgical technique is corpectomy followed by vertebral body reconstruction and stabilisation of the spine. The procedure may be performed in patients in overall good health and a good survival prognosis. The aim of this paper is to present the outcomes of surgical management of spinal metastases in patients who underwent corpectomy followed by vertebral body reconstruction and stabilisation of the spine...

Distal junctional failure (DJF) with fracture at the last instrumented vertebra is a rare occurrence. In this case report, we present two patients with L5 vertebral fracture post-instrumented fusion of the lumbar spine. The first patient is a 78-year-old female who had multi-level degenerative disc disease, spinal stenosis and degenerative scoliosis involving levels T12 to L5. She underwent instrumented posterolateral fusion (PLF) from T12 to L5, and transforaminal lumbar interbody fusion (TLIF) at L2/3 and L4/5...

Between the 80% and 90% of vertebral fractures in over 65 years people are due to osteoporosis. Over the 30% of patients affected by vertebral osteoporosis fractures needs of surgical treatment and the 12% presents complications requiring an invasive surgical approach. We report an unusual case of spontaneous corpectomy and anterior arthrodesis occurred in a patient suffering from Ankylosing Spondylitis. This event invites us to reflect about the magnitude of the biological power of the bone healing, even in adverse conditions...

In subjects with chronic kidney disease (CKD) who suffer a minimal trauma fracture, the problem is to differentiate between osteoporosis and the various forms of renal bone disease associated with CKD-mineral and bone disorder. This problem is exacerbated by the fact that renal osteodystrophy may coexist with osteoporosis. The World Health Organization's bone mineral density (BMD) criteria for osteopenia ( -2.5 < T-score < -1.0) and osteoporosis (a T-score ≤ -2.5) may be used in patients with CKD stages 1-3...

BACKGROUND: Older adults represent a growing proportion of trauma patients treated in the United States, and cervical spine (c-spine) fracture is an injury that is increasingly common in this population. Neck pain is a major component of current clinical clearance guidelines, but some older adults with c-spine fractures report no neck pain after injury. The objective of this study was to investigate the frequency at which c-spine fractures were unassociated with neck pain in an aging population...

Previous reports demonstrated that bone density decreased rapidly during the initial few months of steroid therapy and continued decreasing at a rate of 2 to 4% annually. Our data indicates that denosumab can also play a role in the treatment of osteoporosis in the steroid-taking population. INTRODUCTION: Respiratory physicians are often faced with the dilemma that long-term steroid use will deteriorate bone mineral density and quality. Previous reports demonstrated that bone density decreased 8 to 12% during the initial few months of steroid therapy then continued decreasing at a rate of 2 to 4% annually...

Odontoid process fracture accounts for 5% to 15% of all cervical spine injuries, and the rate is higher among elderly people. The anterior cannulated screw fixation has been widely used in odontoid process fracture, but the fixation strength may still be limited under some circumstances. This study aims to investigate the biomechanical fixation strength of expansive double-threaded bi-directional compression screw (EDBCS) compared with cannulated lag screw (CLS) and improved Herbert screw (IHS) for fixation of type II odontoid process fracture...

BACKGROUND: Avulsion fractures of the pelvic apophyses typically occur in adolescent athletes due to a sudden strong muscle contraction while growth plates are still open. The main goals of this systematic review with meta-analysis were to summarize the evidence on clinical outcome and determine the rate of return to sports after conservative versus operative treatment of avulsion fractures of the pelvis. METHODS: A systematic search of the Ovid database was performed in December 2016 to identify all published articles reporting outcome and return to preinjury sport-level after conservative or operative treatment of avulsion fractures of the pelvis in adolescent patients...

Vertebral hemangiomas are the most common benign vertebral neoplasms and are generally asymptomatic. In the present study, we report the case of a 52-year-old male master ultra-marathoner suffering from a pathologic fracture of the thoracic spine due to a vertebral hemangioma. A further examination in the athlete revealed an accompanying osteopenia, which was most likely due to a deficiency in both vitamin D and testosterone. The treatment of the fracture consisted of percutaneous vertebroplasty. Shortly after the operation the athlete was able to continue running...

Clinical case report and review of the literature. This is the first case of primary leiomyoma in an immunocompetent woman without previous history of uterine leiomyoma being reported in the literature to the best of our knowledge. Leiomyoma, a type of smooth muscle cell tumor, involving the vertebra is extremely rare. There were very few primary leiomyoma in patients with AIDS or in the immune-suppressed patients. This 48-year-old female came with H/o neck pain, weakness and bladder retention. On examination, tone increased in all four limbs, power on the right side of the limbs 4/5, power on the left upper limb 0/5, lower limb 3/5, left plantar was up going, decreased sensation over the left second cervical vertebra (C2) dermatome and all modalities decreased below C2...

BACKGROUND AND AIMS: Restriction of head and neck movements prevents the alignment of the oral, pharyngeal, and laryngeal axes and increases the incidence of difficult tracheal intubation in patients with cervical spine fractures. Video laryngoscopes have gained an important role in the management of difficult intubation, especially in situations with limited head and neck movements. This study compares the success of intubation using Macintosh laryngoscope assisted Bonfils(®) fiberscope (ML-BF) with Truview(PCD) video laryngoscope (TV) in patients with simulated restricted head and neck movements...
