Stem Cells Predicting Orthopedic Outcomes

University of Nebraska

Status: Completed

Conditions: Hip Arthroplasty

Study type: Observational

Funder types: Other

Identifiers

NCT01366911

Details and patient eligibility

About

This is a pilot study to provide preliminary data of the association between bone mineral denity adjacent to acetabular implants, as measured by quanitative computed tomography (QCT), at least 2 years post Total Hip Arthoplasty (THA) surgery with Mesechymal stem cell assays, obtained at time of surgery, and to begin to evaluate if stem cells can predict orthopaedic surgical outcomes.

Full description

Subjects who have undergone a THA and who previously consented to "Stem Cell Quality Assays: Correlation with Aging/Health" study which used excess bone marrow and blood samples to complete stem cell assay labs will be invited back at least 2 years post THA to complete bilateral hip x-rays, if not already completed as part of routine medical follow up plus a QCT bone density testing and to complete a questionnaire regarding smoking, alcohol and exercise history along with recording BMIs.

This ability to identify older individuals with compromised stem cell function could offer opportunities to develop and test new preventative and therapeutic strategies to improve outcomes.

Enrollment: 203 patients

Sex: All

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• subjects who previously had a total hip arthroplasty and had stem cell assays completed on excess bone marrow

Exclusion criteria
