A Randomized Clinical Trial of a Modular Cementless Acetabular Metal on Poly Component Versus a Monoblock Cementless Titanium Shell With Ceramic on Ceramic Bearing and CORAIL Stem: A Bone Mineral Density Study
In Brief
A clinical study evaluating Total hip replacement with titanium shell and CORAIL stem and Total hip replacement with Modular Titanium Femoral Stem for Total Hip Arthroplasty. Completed, enrolled 88 participants across 1 site.
Detailed Summary
The main goal is to prospectively evaluate bone mineral density adjacent to the femoral component and femoral bone remodeling of two different designs: CORAIL impaction broach titanium stem compared to a modular titanium femoral stem (Tri-lock). Patients will be randomized to one of the two treatment groups prior to surgery. Each patient will be evaluated at their regularly scheduled 10-14 days, 3, 6, 12 and 24 month visits following surgery. Patients will be asked to have bilateral DEXA bone mineral density tests (10-14 days post-surgery, and 6, 12 and 24 months post-operatively). Urine and serum samples (measures of bone turnover) will be collected at 3, 6 and 12 months post-operatively after an overnight fast. Patient reported questionnaires will be completed preoperatively and at the 3, 6, 12, and 24 month visits.

Interventions
Patients that are randomized into Group 1 will receive a total hip replacement with the following components: CORAIL (impaction broach) titanium stem and a monoblock cup with ceramic on ceramic bearing (DELTA motion).
Patients that are randomized into Group 2 will receive a total hip replacement with the following components: the Trilock-Pinnacle system (titanium stem and titanium cup with polyethylene insert).
