1. 1. Internal fixation of femoral neck fractures

   Författare :Leif Hernefalk; Linköpings universitet; []
   Nyckelord :Femoral neck fracture; osteotomy; internal fixation; device; technical principles; scintimetry; radiography; biomechanics; malposition; malreduction; complications; bone necrosis; revascularization; segmental collapse; non-union; elderly; osteoporosis; MEDICINE; MEDICIN;

   Sammanfattning : The incidence of femoral neck fractures in elderly people is rising requiring large health care resources. Internal fixation of the fracture is the treatment of choice in Scandinavia, but in 20-40% of the cases a late complication such as a segmental collapse of the femoral head after initial bone necrosis, or a non-union of the fracture because of non-healing, will occur.

4. 3. Displaced femoral neck fractures : studies on osteosynthesis and total hip arthroplasty

   Författare :Gustaf Neander; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :displaced femoral neck fracture; osteosynthesis; total hip arthroplasty; bone mineral measurement; quantitative computed tomography;

   Sammanfattning : The treatment of femoral neck fractures has for many years in Sweden been reduction and osteosynthesis with nails or screws. For displaced fractures the risk of complications such as avascular necrosis and non-union is up to 50 %, often leading to a secondary operation with an arthroplasty. LÄS MER

5. 4. Displaced Femoral Neck Fractures : A prospective randomized study of clinical outcome, nutrition and costs

   Författare :Torsten Johansson; Ola Wahlström; Karl-Göran Thorngren; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Arthroplasty; replacement; hip; adverse effects; economics; fracture fixation; internal; femoral neck fractures; surgery; ossification; heterotropic; etiology; nutritional support; Orthopaedics; Ortopedi;

   Sammanfattning : Displaced femoral neck fractures comprise more than a third of all hip fractures. There is controversy as to the optimal treatment. Despite attempts to improve the methods for internal fixation, complication rates have been almost unchanged: 20-40% non-union and late segmental collapse in another 10-20%. LÄS MER
