Current Augmentation Fixation Techniques for the Osteoporotic Patient

Abstract

Osteoporosis is defined as the deterioration of microarchitecture and overall poor bone quality, which represents a risk of implant fixation failure when patients with osteoporosis are surgically treated. Fragility fractures in elderly patients, typically at the hip, spine and wrist, should be assessed by the orthopaedic surgeon prior to surgery in order to select the most appropriate technique necessary to overcome failures and other complications associated with reduced osteofixation. In this review, advanced methods of augmenting implant fixation in osteoporotic bone are described including polymethylmethacrylate (PMMA), bone grafts, calcium phosphate implants, calcium phosphate cements, calcium phosphate coatings, modified implants and pharmaceutical augmentation concepts. The indication for these techniques should be based on the quantitative assessment of the osteoporotic quality of bone evaluated by dual energy X-ray absorptiometry (DXA).
