[Femoral neck fracture].

The incidence of femoral neck fractures increases exponentially with rising age. Young patients are rarely affected but when they are it is mostly due to high energy accidents, whereas older patients suffer from femoral neck fractures by low energy trauma due to osteoporotic changes of the bone mineral density. Treatment options have not essentially changed over the last few years. Non-operative treatment may be a choice in non-dislocated and impacted fractures. Due to the high risk of secondary fracture displacement prophylactic screw osteosynthesis is recommended even in Garden type I fractures. Osteosynthetic fracture stabilization with cannulated screws or angle stable sliding screws, is usually applied in non-displaced fractures and fractures in younger patients. Older patients need rapid mobilization after surgery; therefore, total hip arthroplasty and hemiarthroplasty are commonly used with a low incidence of secondary complications. In addition to sufficient operative treatment a guideline conform osteoprosis therapy should be initiated for the prophylaxis of further fractures and patients should undertake a suitable rehabilitation.
