PRACTICE PEARLS: Use of a Triflange Cup in Revision THA
The goals of revision total hip arthroplasty are to:
- Restore bone stock
- Achieve component stability
- Restore the hip center of rotation
Acetabular bone loss – particularly in Paprosky 3A and 3B defects and pelvic dissociation – jeopardizes these goals, however, compromising the success of the revision procedure.
Fortunately, Harold E. Cates, MD, from the Tennessee Orthopaedic Clinics in Knoxville, has a solution: the use of triflange cups, which he has found to provide reliable fixation for even the most complex acetabular deficiencies.
In addition, the cup he prefers has a standard locking mechanism that allows him to employ a variety of liners.
Dr. Cates has used triflange cups in dozens of procedures in which the patient had too much bone loss to support a traditional cementless cup. At ICJR’s Pan Pacific Orthopaedic Congress, Dr. Cates reviewed the lessons he has learned, as well as provided his top surgical pearls.
