Trial summary

The primary aim of the study is to compare migration of the cemented Corail stem representing polished surfaced versions of the femoral stem. Two different methods will be used for reaming the femoral canal and cementing of the stem. Radiostereometric analysis (RSA) will be used in migration measurements. Read more about this study

About this study

Official title: Comparison of Two Cementing Techniques of the Femoral Component in a Hip Prosthesis. A Randomized Single-blind Trial

The primary aim of the study is to compare migration of the cemented Corail stem representing polished surfaced versions of the femoral stem. Two different methods will be used for reaming the femoral canal and cementing of the stem. Radiostereometric analysis (RSA) will be used in migration measurements.

Furthermore pain, postoperative outcome and patient satisfaction will be assessed.

Being tested
line-to-line reaming and cementing technique, standard over-reaming with 2 broach sizes

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Difference in subsidence of femoral stems of 200 microns

    Radiostereometric analysis (RSA) of implant migration: difference in translation and rotation (x-, y-, and z- axis) of the femoral stem

    Measured: change from 6th day postoperative to 24 months

Secondary outcomes (5)
  1. Oxford Hip Score

    12 questions. Every question is scored 4 to 0 according to the selected response.

    Thus it is a continuous score ranging from 48-0. Each of the 12 questions on the Oxford hip score is scored in the same way with the score decreasing as the reported symptoms increase (ie. become worse). All questions are laid out similarly with response categories denoting least (or no) symptoms being to the left of the page (scoring 4) and those representing greatest severity lying on the right hand side (scoring 0).

    Measured: change from 6th day postoperative to 24 months

  2. EQ-5D-5L

    5 questions. Every question is scored 1 to 5 where 5 is worse outcome. For example one profile could be' 12233' We then convert this specific health state to an index value specific for that country. The index value calculator can be downloaded from the EuroQol Office. 5 questions. Every question is scored 1 to 5 where 5 is worse outcome. For example one profile could be' 12233' We then convert this specific health state to an index value specific for that country. The index value calculator can be downloaded from the EuroQol Office.

    Measured: change from 6th day postoperative to 24 months

  3. Harris Hip Score (HHS)

    Four subscales make up HHS. The first is pain, which measures pain severity (44 points); function, which is made up of daily activities and gait (47 points); the absence of deformity, which is a subscale that measures hip flexion, adduction, internal rotation, leg length discrepancy and range of motion measures.(4 points), and range of motion (5 points).

    The survey has 10 question items and scores range from 0-100 with higher scores representing less dysfunction and better outcomes.

    Measured: change from 6th day postoperative to 24 months

  4. Visual Assessment Scale (VAS) for pain

    A horizontal or vertical 10 cm line labelled at each end by descriptors such as 'no pain' and 'worse pain ever'. The patient marks the line to indicate pain severity and it is simply quantified by measuring the distance in cm from 0 (no pain) to the patient's marked rating.

    Measured: change from 6th day postoperative to 24 months

  5. Merle D'Aubigne scale

    The score includes the parameters pain, mobility, and ability to walk, with each rated from 0 points (worst condition) to 6 points (best condition). Addition of the scores for pain and mobility results in an absolute estimation of hip function.

    Measured: change from 6th day postoperative to 24 months

Questions about this trial

What is this clinical trial studying?

A study testing line-to-line reaming and cementing technique and standard over-reaming with 2 broach sizes in people with Osteoarthritis, Hip, run by Norwegian University of Science and Technology at 1 site 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 4 inclusion and 6 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 4 May 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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?

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?

Difference in subsidence of femoral stems of 200 microns (time frame: change from 6th day postoperative to 24 months). 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 NCT01952067, which also lists 1 linked publication.

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 4 May 2022.
