The Western world is currently facing an “epidemic” in fractures of the proximal femur. Although the unexplained increase in the age specific incidence seems to have reached a plateau, absolute numbers will continue to rise because of the increasing number of elderly people in the population. Age alone, which inevitably brings a reduction in bone density, does not explain this phenomenon fully....

BACKGROUND Many studies that analyzed bone mineral density (BMD) and skeletal factors of hip fractures were based on uncalibrated radiographs or dual-energy xray absorptiometry (DXA). QUESTIONS/PURPOSES Spatial accuracy in measuring BMD and morphologic features of the femur with DXA is limited. This study investigated differences in BMD and morphologic features of the femur between two types ...

SUMMARY This study is designed to confirm the changes of various bones in the osteopetrotic op/op mouse. The female adult mouse were sonicated in papain solution. After the complete treatment, the bones (Skull, Mandible, Scapula, Humerus, Radius, Ulna, Hip, Femure, Tibia, Atlas, Axis and 5th Lumbar vertebra) were measured three dimensionally using of high quality scale and low power binocular ...

[Purpose] This study aimed to determine static balance according to hip joint angle of the unsupported leg during one-leg standing. [Subjects and Methods] Subjects included 45 healthy adult males and females in their 20s. During one-leg standing on the non-dominant leg, the position of the unsupported leg was classified according to hip joint angles of point angle was class. Static balance was ...

A total of 125 consecutive hip fracture patients were investigated regarding hip geometry. There were 33 men of mean age 76 +/- 10 years, and 92 women of mean age 78 +/- 9 years. Patients with previous hip surgery were excluded. Hip geometry (hip-axis length, width of collum femoris, and femoral shaft and neck-shaft angle) were registered on both plain radiographs and DEXA scans performed withi...

Background: Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease and increases the risk of developing osteoporosis. Incidence fracture higher in this group patients compared to general population can lead increased morbidity (1). Bone strength proximal femur not only linked bone mineral density; it also depends on geometric properties mass (2). Hip structural analysis (HSA) te...

A direct lateral approach to the hip is described which allows adequate access for orientation of the implant, for the insertion ofthe cement and for the correction ofdiscrepancy in leg length. An anatomical observation was made that the gluteus medius muscle is inserted into the greater trochanter by a tendon and that the axis of the shaft of the femur lies anterior to the main bulk of the mus...

Background: The valgus cut angle (VCA) of the distal femur in Total Knee Arthroplasty (TKA) is measured preoperativelyon three-joint alignment radiographs. The anatomical axis of the femur can be described as the anatomical axis of thefull length of the femur or as the anatomical axis of the distal half of the femur, which may result in different anglesin some cases. During TKA, the anatomical ...
