BACKGROUND Two major factors associated with skeletal fracture in older persons are intrinsic bone strength and risk of falling. This study examined the role of Timed Up and Go (TUG) test performance, a validated predictor of falling, and hip areal bone mineral density (BMD), a validated predictor of bone strength in fracture prediction in a 10-year longitudinal study. METHODS The study parti...

Congenital femoral deficiency (CFD) is a spectrum of severity of femoral deficiency and deformity. Deficiency implies a lack of integrity, stability, and mobility of the hip and knee joints. Deformity refers to bone malorientation, bone malrotation, and soft tissue contractures of the hip and knee. Both deficiencies and deformities are present at birth, are nonprogressive, and are of variable d...

Background The ability to follow the distribution and migration of biologically active cells in human is essential for the development of cell-based therapies and diagnostics. Nuclear medicine imaging is widely applied in clinic as an attractive technique for in vivo WBC and stem cell tracking. The aim of this study was to evaluate prosthesis infection of a 51 years old man with previous histo...

PURPOSE The preoperative prevalence of osteoporosis and/or osteopenia and overall bone quality in prospective total knee arthroplasty (TKA) patients may affect the postoperative outcome after prosthetic insertion into the bone. The purpose of this study is to determine the baseline bone mineral density (BMD) and bone turnover in preoperative, female, primary TKA patients. METHODS We prospecti...

OBJECTIVES The objectives of the study were to assess the 2 year BMD changes and their determinants in patients with early inflammatory back pain suggestive of axial spondyloarthritis (SpA) (DESIR cohort). METHODS A total of 265 patients (54% male, mean age 34.4 years) had BMD measurements at baseline and at 2 years. Low BMD was defined as a Z score ≤-2 (at at least one site) and significant ...

OBJECTIVE Alcoholism is a risk factor for osteoporotic fractures and low bone density, but the effects of moderate alcohol consumption on bone are unknown. We performed a systematic review and meta-analysis to assess the associations between alcohol consumption and osteoporotic fractures, bone density and bone density loss over time, bone response to estrogen replacement, and bone remodeling. ...

BACKGROUND The effects of aerobic exercise on bone density at the hip in postmenopausal women in the absence of estrogen replacement therapy are not currently known. The purpose of this study was to examine the effects of aerobic exercise on bone density at the hip in postmenopausal women. METHODS Using the meta-analytic approach, studies dealing with the effects of aerobic exercise on bone d...

Two stage total hip arthroplasty revision surgery includes foreign material debridment, insertion of antibiotic impregnatedcement spacer, and finally, reimplantation of the prosthesis. This review has aimed to evaluate the efficacy of antibioticimpregnated cement spacers in infection control and eradication in arthroplasties.A total of 85 articles on total hip arthroplasty wer...

background: a growing body of investigations demonstrated the essence role of zinc on growing and maintaining bone tis sue .the idea that zinc could enhance bone content and adjourn or prevent osteoporosis in men, has been experimented as a hy pothesis. methods: six hundred healthy men (age 20-69 yr) through iranian multicenter osteoporosis study (imos) which is a na tional project running in 5...

Background and Aim: Temporomandibular joint osteoarthritis (TMJOA) appears to be more common in osteoporotic patients. Fractal analysis is a mathematical method that can be used to assess trabecular bone. The aim of this study was to assess the correlation of bone mineral density (BMD) and fractal dimension (FD) of the condyles in women with TMJOA using cone-beam computed tomography (CBCT).   ...
