Closed reduction and internal fixation with two parallel screws (Olmed)
Procedure: Internal fixation
Fluoroscopic Control. Percutaneous. FWB. Two parallel screws (Olmed)
Other Name: Olmed (DePuy)
Hemiarthroplasty with Charnley/ Hastings prosthesis
Procedure: Bipolar hemiarthroplasty
Lateral approach. FWB.
Other Name: Charnley/Hastings
Patients were included from 2002-2004. Two years follow up was finished by 2006. Patients with displaced intracapsular femoral neck fractures were included and randomized by means of closed numbered envelopes to operation groups:
- Two parallel screws (Olmed).
- Hemiarthroplasty with Charnley/ Hastings prosthesis.
A priori one would expect that there would be less morbidity and mortality with the less extensive and quicker operation with parallel screw and that a faster and better rehabilitation would be achieved with hemiarthroplasty.
