Abstract:
Hip fracture occurs relating to fall and decreased mechanical integrity of the femoral neck. Mechanical strength of the femoral neck is determined by both bone mineral density and other factors such as bone quality and hip geometry. Histomorphometrical studies show that cortical thinning, regional hyper-mineralization, decreased osteocyte lacunae and microdamage accumulation occur in aged or fractured subjects, suggesting that bone quality contributes mechanical integrity of femoral neck. Recent dual energy X-ray absorptiometry (DXA) studies revealed that hip axis length, longer in femoral neck fracture patients may contribute to the risk of femoral neck fracture.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
Gross Anatomy of Bone
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in adults, it...
