Extract

The loss of bone mass and consequently bone strength in persons aged forty and beyond is a continuing problem to the orthopaedic community. This progressive loss has been documented by various means such as radiographs, autopsy materials, CAT scans, and single or dual photon absorptiometrv. Orthopaedic problems arising from osteoporosis include fractures of the lumbar spine, distal radius and the femoral neck. Likewise, this age group represents the fraction of the population that will require prosthetic replacement of a joint. Unfortunately, little information is available concerning the mechanical properties of osteoporotic bones and its interaction with prosthetic devices.
