About

Uncemented Hemiarthroplasty, Radiological Features Comparing Lateral Versus Anterolateral Approach. Comparing leg length discrepancy, femoral offset, valgus/varus position of the stem. Also is there a difference in heterotopic ossification at 12 months.

Full description

Between January 2014 and July 2017 a RCT was conducted at Sorlandet Hospital Kristiansand, Norway. The trial was approved by the regional ethics committee (2013/1853/REK) and registered at ClinicalTrials.gov (ClinicalTrials.gov Identifier NCT02028468). This study is a follow-up on the same study population.

150 patients (70 to 90 years) with a displaced femoral neck fracture was randomized to be operated With either anterolateral og Direct lateral surgical approach. Investigators want to compare the radiological features of the femoral stem between the two Groups.
