A Prospective Randomized Trial of Uncemented Versus Cemented Hemiarthroplasty for Displaced Femoral Neck Fractures - Full Text View

ClinicalTrials.gov Identifier:	NCT00491673

Purpose

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
