About this study

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

Questions about this trial

What is this clinical trial studying?

A study testing Uncemented primary bipolar hemiarthroplasty of the hip and Cemented primary bipolar hemiarthroplasty of the hip in people with Femoral Neck Fractures, run by Ullevaal University Hospital at 2 sites in Norway.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 24 Sep 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Norway. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Functional outcome including pain (Harris Hip Score) (time frame: 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Sep 2010.
