About this study

Official title: Collection of Bone Specimens for Testing of A Special Vessel Subtype

RATIONALE: Collecting and storing bone samples from patients with osteoporotic and nonosteoporotic fracture to study a special vessel subtype in the laboratory may help surgeon learn more about the relationship between bone mineral density (BMD) and a special vessel subtype (type H vessel).

PURPOSE: This research study is looking at changes of a special vessel subtype in bone samples from patients with osteoporotic and nonosteoporotic fracture.

Read the detailed description

OBJECTIVES:

  1. Establish type H vessel in bone specimen in patients with hip fracture.
  2. Explore the correlation of BMD and type H vessel.

OUTLINE:

  1. Collect human bone specimens from patients with Osteoporotic and Nonosteoporotic Fracture.
  2. Provide a repository for storage of tissue and make these specimens available for approved projects by laboratory-based investigators.
  3. Observe the type H vessel in bone slice by immunofluorescence staining.
  4. Collect clinical data on these patients including bone mineral density.
  5. Investigate the relationship between BMD and type H vessel.
Being tested
total hip arthroplasty or proximal femoral nails

What is being measured

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

  1. The area of a special vessel subtype in human bone samples

    Bone samples were fixed in 4% PFA, decalcified, dehydrated, embedded and immunofluorescent staining for 3 months. Calculate the proportion of the special vessel of total vessel.

    Measured: 3 months

Secondary outcomes (2)
  1. The value of bone mineral density

    Bone mineral density was measured by double energy X-ray absorptiometer (DXA) in a week before surgery.

    Measured: 1 week

  2. Correlation of of bone mineral density and area of a special vessel subtype in human bone

    Calculate correlation coefficient of BMD and type H vessel in human bone samples in 2 months.

    Measured: 2 months

Questions about this trial

What is this clinical trial studying?

A study testing total hip arthroplasty or proximal femoral nails in people with Femoral Neck Fractures, run by Second Affiliated Hospital of Soochow University at 1 site in China.

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 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 25 Apr 2016. 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 China. 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. Some participants in this study may receive a placebo. 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?

The area of a special vessel subtype in human bone samples (time frame: 3 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 NCT02750046, which also lists 5 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 25 Apr 2016.
