[Hip fractures in the elderly : Osteosynthesis versus joint replacement].

Background Osteoporotic fractures of the femoral neck and trochanteric region pose an ever-expanding existential problem both for the individual and for society. Despite numerous innovations and advances regarding implant design, mortality and the systemic and mechanical complication rates remain high. Objectives Depiction of treatment options for femoral neck fractures and trochanteric femur fractures in the elderly comparing joint replacement and osteosynthesis. Methods A search of the Medline, Embase and Cochrane databases was carried out focusing on hip fracture treatment. Randomized or quasi-randomized controlled trials, meta-analyses and reviews comparing joint replacement or fixation implants in the elderly were included. Results Displaced fractures of the femoral neck often require total joint arthroplasty whereas trochanteric fractures are amenable to internal fixation. Cemented total hip replacement as opposed to cementless techniques is recommended in the elderly and yields good functional results in active patients. Hemiarthroplasty is the treatment of choice in infirm patients with multiple comorbidities and cognitive impairment. Trochanteric fractures (AO/OTA types A1 and A2) can be successfully treated with intramedullary or extramedullary fixation. Adequate reduction and stable fixation are prerequisites for uneventful healing. A meticulous operative technique can prevent iatrogenic complications. Conclusion In summary, there are many parameters affecting the outcome in the treatment of fragility and hip fractures. Technical features as well as surgeon characteristics play an important role and the ultimate solution has yet to be developed. Even though fracture morphology may indicate a specific treatment option, patient characteristics play an important role in decision-making. The development of centers of fragility fracture care in Germany could help to lower the complication rate and increase quality of life in hip fracture patients in the future.
