Trial summary

The aim of hip replacement surgery is to re-establish the physiological hip function and to obtain a stable fixation between the prosthetic components and the native bone. Commonly, the fixation is obtained by bone ingrowth between the prosthesis and the native bone. Read more about this study

About this study

Official title: Analysis of the Osteogenic Potential of Multipotent Cells From Different Anatomical Regions in Hip Replacement Surgery

The aim of hip replacement surgery is to re-establish the physiological hip function and to obtain a stable fixation between the prosthetic components and the native bone. Commonly, the fixation is obtained by bone ingrowth between the prosthesis and the native bone. Thus, the quality of the patient's bone stock is essential to achieve this aim. However, several clinical conditions may impair the bone stock; therefore, in these cases bone grafts are necessary to improve the prosthetic fixation. The gold standard is represented by autologous bone grafts (from iliac crest or from acetabular bone chips) or allogeneic bone grafts from cadaveric femoral heads. Nevertheless, the osteogenic potential of multipotent cells derived from different anatomical regions has never been examined.

Thus, the aim of this study is to isolate multipotent cells from acetabular or femoral bone chips and from bone marrow aspirate of the same patient and to compare their osteogenic potential. The results of this study may reveal differences, which may have a clinical relevance for hip replacement surgery.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Isolation of multipotent cellsBiological

    Isolation of multipotent cells from patient's cells. Analysis of CFU and differentiation potential

What is being measured

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

  1. Evaluation of differences in Colony Forming Units (CFU) percentage

    Formation of CFUs will be evaluated in the three different samples (acetabular bone chips, femoral bone chis or bone marrow aspirated) and CFUs will be counted in each sample

    Measured: 6 months

Secondary outcomes (3)
  1. Evaluation of the osteogenic potential in the three different cell populations

    Evaluation of Alizarin red stain. Analysis of bone markers (RUNX2, Collagen type I, Collagen type X, Alkaline Phosphatase)

    Measured: 1 year

  2. Evaluation of the chondrogenic potential in the three different cell populations

    Evaluation of Alcian blue stain in pellet culture. Analysis of chondrogenic markers (Collagen type II and SOX9)

    Measured: 1 year

  3. Evaluation of the adipogenic potential in the three different cell populations

    Evaluation of Oil red stain. Analysis of adipogenic markers (Peroxisome proliferator-activated receptor gamma (PPAR-γ), Lipoprotein lipase (LPL))

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Complications; Implant, Orthopedic, run by I.R.C.C.S Ospedale Galeazzi-Sant'Ambrogio at 1 site in Italy.

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 7 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 16 Apr 2019. 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 Italy. 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?

Contact Laura Mangiavini, Dr (00390266214930, laura.mangiavini@grupposandonato.it), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Evaluation of differences in Colony Forming Units (CFU) percentage (time frame: 6 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 NCT03369457, 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 16 Apr 2019.
