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.

Hip Arthroplasty

Study Type: Observational
Study Design: Time Perspective: Prospective
Official Title: Can Stem Cells Predict Orthopaedic Outcomes? The Correlation of Bone Density Findings Post Total Hip Arthoplasty With Stem Cell Assays Obtaned at Time of Surgery

Further study details as provided by University of Nebraska:

Primary Outcome Measures:
  • Can Stem Cells Predict Orthopaedic Outcomes? [ Time Frame: Enrollment expected to begin June 2011and this pilot study is expected to be completed by May 2012. ]
    Bone mineral density adjacent to acetabular implants will be evaluated using QCT which can show early bony changes, which can provide information about the quality of implant fixation and surrounding bone adaption. X-rays will evaluate component loosening, wear, alignmet and osteolytis. Patient characteristics will be summarized using descriptive statistics. Spearman correlation coefficients will be used to assess the association of Mesenchymal stem cell assays and bone density findings.

Estimated Enrollment: 50
Study Start Date: April 2011
Estimated Study Completion Date: April 2012
Estimated Primary Completion Date: April 2012 (Final data collection date for primary outcome measure)
stem cell QCT testing

Detailed 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.
