Abstract:
Osseointegration is a term that refers to the formation of a direct interface between an implant and bone without intervening soft tissue. Cementless femoral fixation in total hip arthroplasty is dependent on mechanical and biological factors that affect implant stability and long-term outcome. Osteoporosis leads to morphological and biological alterations in the proximal femur that adversely affect both mechanical stability of implant and biological response of bone, making it more challenging to achieve a valid osseointegration.

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
