Treatment of femur neck fractures is often challenging, especially in adults aged under 55–60 years. Despite improved medical care and modern implant technology, complication rates are still high. Nearly 20% of patients require a second surgery. Death, non-union, infection, implant failure, avascular necrosis of the femur head, and shortening of the femur neck are commonly seen complications. Despite advanced medical facilities, mortality rates of up to 30% are seen at the end of the first year of the treatment. In the cases of implant failure and non-union of the femoral neck fractures of young patients, re-osteosynthesis of the fracture or proximal femoral osteotomies are used to preserve the native femoral head. In the elderly arthroplasty is the preferred choice of treatment method. In patients who develop femoral head avascular necrosis, the best treatment is often total hip arthroplasty. Being under 60 years of age, female gender, and displaced fractures are known as risk factors for avascular necrosis of the femoral head. In order to avoid complications, optimum care should be given to technical rules and tissue viability while caring the patients.
