BACKGROUND: The estimated incidence of osteoporotic pelvic fractures among persons over age 60 in Germany is 224 per 100 000 persons per year, and rising. A number of surgical treatment options are available, but clinical long-term data are lacking. METHODS: This review is based on pertinent publications and guidelines retrieved by a selective literature search, and on the authors' clinical experience. RESULTS: Patients often report one or more relatively trivial traumatic incidents leading up to the fracture...

Fracture risk increases as type 2 diabetes (T2D) progresses. With the rising incidence of T2D, in particular early-onset T2D, a representative pre-clinical model is needed to study mechanisms for treating or preventing diabetic bone disease. Towards that goal, we hypothesized that fracture resistance of bone from diabetic TallyHO mice decreases as the duration of diabetes increases. Femurs and lumbar vertebrae were harvested from male, TallyHO mice and male, non-diabetic SWR/J mice at 16 weeks (n ≥ 12 per strain) and 34 weeks (n ≥ 13 per strain) of age...

OBJECTIVE: To investigate the effect of grip strength on bone mineral density (BMD) in postmenopausal women. Low BMD is related to risk of fracture and falling is the strongest factor for fragility fractures. Handgrip strength is a reliable indicator of muscle strength and muscle strength is associated with falling. METHODS: For the present study 120 women were divided into two groups: those ≤65 years and those >65 years. Serum 25 hydroxyvitamin D (25OHD), BMD, and handgrip strength were measured to observe the effect of age on 25OHD, grip strength, and BMD, as well as the effect of 25OHD on grip strength and BMD...

PURPOSE: Polymethylmethacrylate (PMMA) augmentation is a common method to increase pullout strength fixed for osteoporotic spines. However, few papers evaluated whether these pedicle screws migrated with time and functional outcome in these geriatrics following PMMA-augmented pedicle screw fixation. METHODS: From March 2006 to September 2008, consecutive 64 patients were retrospectively enrolled. VAS and ODI were used to evaluate functional outcomes. Kyphotic angle at instrumented levels and horizontal and vertical distances (HD and VD) between screw tip and anterior and upper cortexes were evaluated...

The incidence of thoracolumbar spine fractures in blunt trauma is 4 to 5 per cent. These fractures may lead to neurologic injury, chronic back pain, and disability. Most studies from United States trauma centers focus on neurologic sequelae and/or compare treatment modalities. However, most patients with spine fractures do not have a neurologic deficit. Our primary objective was to determine the long-term outcome of traumatic thoracolumbar spine fractures, specifically addressing quality of life, chronic pain, and employment using a validated patient outcome survey...

OBJECTIVE: Higher incidence of osteopenia and osteoporosis underlie increased rates of fragility fracture in HIV infection. B cells are a major source of osteoprotegerin (OPG), an inhibitor of the key osteoclastogenic cytokine receptor activator of nuclear factor-κB ligand (RANKL). We previously showed that higher B-cell RANKL/OPG ratio contributes to HIV-induced bone loss. T-cell OPG production in humans, however, remains undefined and the contribution of T-cell OPG and RANKL to HIV-induced bone loss has not been explored...

Annual intravenous administration of zoledronic acid is used in the treatment of osteoporosis. A mathematical model was developed to predict bone mineral density up to 2 years after two annual doses of zoledronic acid from the early values of a bone resorption marker in osteoporosis patients. INTRODUCTION: The measurement of bone mineral density (BMD) has been used as a surrogate marker instead of the observation of incident fractures to detect the efficacy of treatment. However, this method requires a long time to obtain significant changes...

OBJECTIVE: To assess the effect of Accountable Care Organizations (ACOs) on the use of surgical services among racial and ethnic minorities. BACKGROUND: Health reform efforts were expected to reduce healthcare disparities. The impact of ACOs on existing disparities in access to surgical care remains unknown. METHODS: We used national Medicare data (2009-2014) to compare rates of surgery among white, African American, Hispanic, and Asian Medicare beneficiaries for coronary artery bypass grafting, colectomy, total hip arthroplasty, hip fracture repair, and lumbar spine surgery...

STUDY DESIGN: A case report. OBJECTIVE: To outline the potential risks of late bleeding from the segmental vessels following less invasively dorsolateral approaches to the thoracolumbar spine. SUMMARY OF BACKGROUND DATA: A low risk of major intraoperative bleeding, associated traditional dorsolateral approach to the lumbar spine is reported , but segmental arteries and great vessels may be rarely damaged. Spine surgeons who are involved with these approaches should be aware of these rare but potential dangerous vascular complication because they could be life threatening, particularly in elderly patients with increased morbidity, and/or metastatic disease to the spine...

Introduction: The trabecular bone score (TBS) is a gray-level textural metric that can be extracted from the two-dimensional lumbar spine dual-energy X-ray absorptiometry (DXA) image. TBS is related to bone microarchitecture. Several literature data suggest that TBS predicts fracture risk as well as lumbar spine bone mineral density (LS-BMD) measurements in postmenopausal women. Objective: A retrospective case-control study assessing the ability of the TBS to predict spine fragility fractures (SFF) in postmenopausal women with or without osteoporosis (diagnosed by T-score≤-2...

BACKGROUND: Patients with ankylosing spines are susceptible to developing spinal fractures even with minor trauma and can develop early or late neurological injuries. These fractures require early and aggressive surgical management to enable spinal stability and/or neural decompression. Being highly unstable by nature, they require relatively long segment instrumentation and fusion, which can increase paravertebral soft tissue damage and perioperative bleeding. The purpose of this report is to describe a rare case of traumatic double fractures at the cervico-thoracic and thoraco-lumbar transition zones in ankylosing spine with spondylo-epiphyseal dysplasia (SED) of unknown cause, which were successfully treated with a combined open and percutaneous spinal fusion procedure...
