Trial summary

Postoperative periprosthetic femoral fracture after hip arthroplasty is associated with considerable morbidity and mortality. Recent cohort studies have demonstrated a high incidence of PPF in elderly patients treated with two commonly used polished, tapered, collarless stems in elderly patients. Read more about this study

  • Older adult

Study population: We included all patients above the age of 80 years old, operated between September 2009 and April 2015 with a primary hip arthroplasty for an acute displaced femoral neck fractures. Patients were treated either with the cemented CPT or SP2 stems.

About this study

Postoperative periprosthetic femoral fracture after hip arthroplasty is associated with considerable morbidity and mortality. Recent cohort studies have demonstrated a high incidence of PPF in elderly patients treated with two commonly used polished, tapered, collarless stems in elderly patients. The aim of this study was to compare the rate and characteristics of PPF in a consecutive cohort of patients treated either the polished tapered CTP stem or the matte anatomic SP2 stem in an elderly population above 80 years of age with femoral neck fracture.

Questions about this trial

What is this clinical trial studying?

An observational study of Hip Fracture and Femoral Neck Fracture, run by Sundsvall Hospital.

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 1 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: finished, as of the sponsor's last update on 12 May 2016. Status can change between updates, so confirm with the study contact before making plans.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Incidence of periprosthetic femoral fracture (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02591342, which also lists 3 linked publications.

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 12 May 2016; AzTrials last refreshed its copy on 7 Nov 2026.
