BACKGROUND: In cases of Kümmell's disease without neuro deficit, percutaneous vertebroplasty or Kyphoplasty have achieved short-term favorable outcomes. In the long term, re-collapse of the augmented vertebral body and aggravation of the kyphosis at the index level is often reported. On the other hand, owing to medical comorbidities, the elderly are often not suited for extensive open spine surgery under general anesthesia. CASE DESCRIPTION: A 95-year-old man presented with a one-month history of intractable back pain and gait disturbance...

Vitamin D receptor (VDR) is one of the main mediators of vitamin D biological activity. VDR dysfunction might substantially contribute to development of postmenopausal osteoporosis (PMO). Numerous studies have revealed the effects of several VDR gene variants on osteoporosis risk, although significant variation in different ethnicities have been suggested. The main purpose of this work was to assess the frequency of distribution of VDR genetic variants with established effect and evaluate their haplotype association with the risk of PMO in a cohort of Belarusian and Lithuanian women...

OBJECTIVE: To compare the efficacy of long and short segment instrumentation following pedicle subtraction osteotomy (PSO) for thoracolumbar kyphosis caused by ankylosing spondylitis (AS). METHODS: Sixty-four consecutive AS patients were analyzed and divided into groups according to length of instrumentation. We defined short segment instrumentation (SSI) as construct length less than 7 levels (3 levels above and below the osteotomy or less) (n=17). In contrast, long segment instrumentation (LSI) was defined as construct length equal to or greater than 7 levels (4 levels above and 3 levels below the osteotomy or more) (n=47)...

PURPOSE: The role of glucocorticoids in the treatment of rheumatoid arthritis (RA) is widely debated. Impairment of bone formation may be counter-balanced by reduced systemic inflammation. This review aims to assess the effect of prednisolone/prednisone on bone mineral density (BMD) in patients with RA analyzed in randomized, controlled trials. METHODS: We performed a systematic literature search and identified randomized, double-blinded placebo-controlled studies including patients with RA and using prednisolone or prednisone as the intervention...

L Pietrogrande, E Raimondo
Abaloparatide is a synthetic 34-amino acid peptide analogue of the 1-34 portion of the human parathyroid hormone-related protein (PTHrP). It has been approved in the U.S. for the treatment of postmenopausal women with osteoporosis at a high risk for fracture. Abaloparatide is an anabolic agent and it seems to have a potent anabolic activity with reduced effects on bone resorption. It reduces the risk of vertebral and nonvertebral fractures, major osteoporotic fractures and clinical fractures, with a significant improvement in bone mineral density at femoral neck, total hip and lumbar spine...

BACKGROUND: The patients with secondary hyperparathyroidism (SHPT) usually had reduced bone mineral density, which might lead to a substantial increase in osteoporosis, fracture and mortality. Although surgical intervention is effective in reducing parathyroid hormone (PTH) levels in suitable candidates refractory to medical therapy, the effect of surgery on bone mass changes still requires further evaluation. Thus, the aim of this study was to evaluate the characteristics of BMD changes after total parathyroidectomy (PTX) without autotransplantation and its associated factors...

The aim of the present study was to assist rheumatologists in differentiating hypophosphatemic osteomalacia (HO) from mimic rheumatology diseases. Clinical data was obtained from 9 patients with acquired HO, initially misdiagnosed as mimic rheumatologic diseases. The data were retrospectively analyzed and a literature review was performed. The etiology of the cases was as follows: Adefovir dipivoxil-induced Fanconi syndrome was present in 6 of the cases, 2 were tumors and 1 case was chronic nephropathy. The chief complaint was thoracic or back pain and arthralgia, followed by progressive muscle weakness and dramatic movement limitation...

Evan Luther, Timur Urakov, Steven Vanni
BACKGROUND AND STUDY OBJECTIVE:  Complex traumatic lumbar spine fractures are difficult to manage and typically occur in younger patients. Surgical immobilization for unstable fractures is an accepted treatment but can lead to future adjacent-level disease. Furthermore, large variations in fracture morphology create significant difficulties when attempting fixation. Therefore, a surgical approach that considers both long-term outcomes and fracture type is of utmost importance. We present a novel technique for percutaneous fixation without interbody or posterolateral fusion in a young patient with bilateral pedicle dissociations and an acute-onset incomplete neurologic deficit...

Background: The conventional interlaminar approach is adequate for access to most disc herniations in lumbar spine surgery. The access to cranially and caudally migrated disc fragments, by conventional interlaminar fenestration, requires an extension of the fenestration with the potential destruction of the facet joint complex and consequent postsurgical instability. To describe the technique and results of the translaminar technique of targeted discectomy using tubular retractors for the surgical treatment of cranially and caudally extruded discs...

BACKGROUND: Percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) are two common procedures that could be applied simply in treatment of vertebral compression fractures (VCFs). Despite simplicity and safe application of these procedures, there are some drawbacks as well. The cement leakage into spinal canal is mostly seen complication of PVP and PKV procedures. The aim of this article is to present a minimally invasive alternative technique for removing cement leakage fragment after the PVP...

BACKGROUND: Osteoporotic vertebral compression fracture (OVCF) is a common type of fracture, and percutaneous kyphoplasty (PKP) is an eligible solution to it. Previous studies have revealed that both the volume and filling pattern of bone cement correlate with the clinical outcomes after PKP procedure. However, the role of bone cement distribution remains to be illustrated. METHODS: To retrospectively evaluate the relationship between the bone cement distribution and the clinical outcomes of unilateral PKP, we enrolled 73 OVCF patients receiving unilateral PKP treatment...

BACKGROUND: Studies using dual energy X-ray absorptiometry (DXA) demonstrate a reduction in bone mineral density (BMD) in children and adolescents with Turner syndrome (TS). However, these studies do not take into account changes in bone size, which influence BMD in the case of short-statured patients. Phalangeal quantitative ultrasound (phQUS) measurements have shown an ability to reveal changes due to skeletal growth, aging, and bone and mineral disorders. There is limited data on bone mineral status in girls with TS assessed by 2 different techniques, i...

An 8-y-old lactating Holstein cow was presented to the herd veterinarian with a history of acute ataxia, and because of poor prognosis, the animal was euthanized and submitted for postmortem examination. A lumbar vertebra was incompletely fractured and had an adjacent subdural hematoma. The pancreas had a hard texture with exaggerated nodular appearance, and on cut surface, the pancreatic ducts appeared fibrotic and contained scores of round-to-faceted pancreatoliths of 0.5-2.0 mm diameter. These calculi extended from the major ducts to the pancreatic duct, sphincter, and into the duodenal lumen...

BACKGROUND: People living with HIV (PLWH) commonly have low bone mineral density (BMD) (low bone mass and osteoporosis) and are at high risk for fractures. Fractures and low BMD are significant causes of morbidity and mortality, increasingly relevant as PLWH age. Alcohol use is common among PLWH and known to affect bone health. The association between alcohol use and changes in BMD among PLWH is not well understood. METHODS: We conducted a 3.5-year prospective cohort study of 250 PLWH with substance use disorder or ever injection drug use...

INTRODUCTION: The bone mineral density (BMD) status of dancers is currently unknown. Some research indicates that female dancers have no difference or higher BMD than non-dancers. Other evidence indicates they have lower BMD, predisposing them to osteoporosis and fractures later in life. These differences among studies may be due to differences in dancer type, age, level, and lack of control of confounding variables. Few studies have been completed on college-level dancers. PURPOSE: To evaluate BMD in female college-level dance majors...
