Osteoporotic femoral neck fractures: management and current controversies.

ÌÇÐÄ´«Ã½

Abstract

Osteoporosis is a pervasive disease among the growing elderly population. Femoral neck fractures are often a direct result of osteoporosis and are challenging to treat. Surgical interventions seek to return the patient to preinjury function as quickly as possible, but many obstacles exist. Disruption of the blood supply occurs regardless of the fracture pattern, and in the active elderly population, reduction and fixation should be done as soon as possible to minimize healing problems. Closed reduction with percutaneous cannulated screw instrumentation is currently the fixation method of choice, but even with meticulous technique, moderate complication rates persist. Newer devices and biologic bone augmentation cement show promise in decreasing postoperative fracture collapse. Patients in whom a stable reduction cannot be achieved or who have a limited life expectancy should undergo arthroplasty. Unipolar and bipolar arthroplasty have both been effective in restoring function and have been the standard of care in these patients. Recent evidence suggests that active elderly patients who have acetabular disease or severely displaced fractures may benefit most from primary total hip arthroplasty.
