Brief Summary:
The purpose of this study is to evaluate whether an uncemented hip prosthesis is as safe as an cemented hip prosthesis for patients undergoing total hip arthroplasty surgery following a displaced femoral neck fracture.

Condition or disease Intervention/treatment Phase
Hip Fractures Procedure: Uncemented femoral stem Procedure: Cemented femoral stem Not Applicable

Detailed Description:
The study will randomize patients between an uncemented and cemented stem
