DFACTO: Displaced Femoral (neck fx) Arthroplasty Consortium for Treatment and Outcomes

This research study is a prospective randomized multicenter study comparing total hip arthroplasty (THA) to hemiarthroplasty in the treatment of Garden III and IV displaced femoral neck fractures. The comprehensive approach measures functional outcome in physically active, non-institutionalized hip fracture patients who are without concurrent hip disease at 6, 12, 18, and 24 months post-fracture. The primary outcomes are validated measures of functional status (SF-36, Western Ontario and McMaster University Osteoarthritis Index {WOMAC}, the Harris Hip Score and the Timed Up and Go Test). Although we anticipate that the functional outcomes at 6 months between the two groups will be similar, we expect to observe a significant divergence in functional status between the groups at two years.

This study of 300 patients is being conducted at several hospitals which include: Columbia University Medical Center, New York, NY, The North Shore Medical Center, Lynnfield, MA; Lahey Clinic, Burlington, MA; University of Pennsylvania, Philadelphia, PA; University of California at San Francisco, San Francisco, CA; University of Nebraska Medical Center, Omaha, NE; Baylor College of Medicine, Houston, TX; Lakewood Orthopaedic Surgeons, Tacoma, WA; Tri-County Orthopaedic & Sports Medicine, Morristown, NJ; Sinai Hospital of Baltimore, Baltimore, MD.
