Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

There is increasing evidence that primary hemiarthroplasty is the treatment of choice for displaced femoral neck fractures in the elderly

No definite conclusions have been made in regards to what kind of arthroplasty is favourable

Cemented implants are associated with increased risk of perioperative cardiovascular incidents and increased mortality.

Cementless implants are associated with increased postoperative pain and decreased walking ability.

This study investigates the differences between one well-documented cemented femoral stem and one well-documented uncemented femoral stem. Previous studies have mostly used uncemented stems with different designs.

Null hypothesis: No (less than 10 points) difference in HHS between groups at 1 year and 5 years

Detailed Description

Inclusion Criteria: Dislocated intracapsular femoral neck fracture in patients ≥ 70 years old Exclusion criteria: Pathological fracture, Systemic or local infection, Short life expectancy/not mobile at all, Symptomatic coxarthrosis.

Null hypothesis: No (less than 10 points) difference in HHS between groups at 1 year (SD of HHS is 15 points) Power: 95% Significance: 0.05 60 patients in each group needed. To compensate for high mortality and drop-out: 200 patients, 100 in each group
