background: bisphosphonates (bps) are used extensively for managing the osteoporosis. there are some controversies on atypical fractures of femur that associated with increase in cortical thickness (ct) and bps' use. in this study, the effects of alendronate consumption were studied on femoral ct as a predictor for atypical fracture.   methods: forty nine post-menopausal women aged 50-70 years ...

BACKGROUND As longevity of cementless femoral components enters the third decade, concerns arise with long-term effects of fixation mode on femoral bone morphology. We examined the long-term consequences on femoral remodeling following total hip arthroplasty with a porous plasma-sprayed tapered titanium stem. METHODS Clinical data and radiographs were reviewed from a single center for 97 rand...

Revision surgery of the hip was performed on 114 hips using an extensively porous-coated femoral component. Of these, 95 hips (94 patients) had a mean follow-up of 10.2 years (5 to 17). No cortical struts were used and the cortical index and the femoral cortical width were measured at different levels. There were two revisions for aseptic loosening. Survivorship at 12 years for all causes of fa...

The purpose of our study was to investigate the radiographic characteristics of atypical femoral shaft fractures (AFSFs) in females with a particular focus on femoral bow and cortical thickness. We performed a fracture location-, age-, gender-, and ethnicity-matched case-control study. Forty-two AFSFs in 29 patients and 22 typical osteoporotic femoral shaft fractures in 22 patients were enrolle...

BACKGROUND This study assessed the differences in femoral geometry and bone mineral density between femoral neck fragility fractures and trochanteric fractures. METHODS One hundred and seventeen patients were divided into femoral neck and trochanteric fracture groups. There were 69 patients with femoral neck fractures, 20 men and 49 women with an average age of 75.1 ± 9.6 years and an average...

this study was aimed to investigate the use of panoramic radiography in patients with low bone mineral density (bmd) in order to diagnose and prevent osteoporotic fractures. panoramic radiographs of 60 patients  (20 men and 40 women) aged from 40 to 70 years with cortical thicknesses of less than 3 mm in the mandibular angle were selected from patients referred to a dentomaxillofacial radiology...

Skeletal growth is explored between Early Neolithic (EN) (8000 to 6800 BP) and Late Neolithic (LN) (6000 to 5200 BP) foragers from the Cis-Baikal region of Eastern Siberia. Previous studies suggest that increased systemic stress and smaller adult body size characterize the EN compared to LN. On this basis, greater evidence for stunting and wasting is expected in the EN compared to LN. Skeletal ...

The local structure of the proximal femoral cortex is of interest since both fracture risk, and the effects of various interventions aimed at reducing that risk, are associated with cortical properties focused in particular regions rather than dispersed over the whole bone. Much of the femoral cortex is less than 3mm thick, appearing so blurred in clinical CT that its actual density is not appa...

PURPOSE To assess the Dorr proximal femoral types and the cortical thickness index for predicting peri-operative complications during hemiarthroplasty. METHODS Records of 53 male and 147 female elderly who underwent cemented or uncemented monopolar hemiarthroplasty for displaced intracapsular femoral neck fractures were reviewed. Any intra-operative fracture and postoperative dislocation with...

INTRODUCTION: Alendronate (Aln) is a bisphosphonate agent that has been widely used for the treatment of osteoporosis. Recently, several studies have suggested an association between long-term use of Aln and the occurrence of low-energy subtrochanteric/femoral shaft (ST/FS) fractures. Previous studies described characteristic imaging features of this atypical fracture including transverse orien...
