Comparing Collared and Collarless Femoral Stems in Primary Total Hip Arthroplasty
Sponsor: Medstar Health Research Institute
Summary
This is a prospective randomized control trial comparing two collared and collarless femoral implants used in primary total hip arthroplasty. The specific aims of this trial are to: SA1: Prospectively assess clinical outcomes in patients undergoing primary total hip arthroplasty with a collared versus collarless femoral stem of the same design. SA2: Evaluate serial radiographs to quantify differences in subsidence between collared and collarless implant groups. SA3: Report and compare incidence rates of intraoperative and postoperative periprosthetic fractures and aseptic loosening following primary total hip arthroplasty with use of either a collared or collarless stem. Hypothesis: The addition of a collar to the same designed triple-taper primary hip stem will lead to a reduction in subsidence and incidence of perioperative and periprosthetic femur fractures.

Interventions
Collarless Femoral Stem
Patients will be randomized to one of two groups receiving either a collarless or collared femoral stem. Patients randomized to this group will receive a collarless femoral stem implant at time of surgery.
Collared Femoral Stem
Patients will be randomized to one of two groups receiving either a collarless or collared femoral stem. Patients randomized to this group will receive a collared femoral stem at the time of surgery.
