Summary

Converting fused hips to total hip arthroplasty can improve patient function, though outcomes are less satisfactory than routine procedures. Careful planning is essential for optimal results in these complex hip surgeries.

Area of Science:

  • Orthopedic Surgery
  • Reconstructive Surgery

Background:

  • Ankylosed or arthrodesed hips present unique challenges for total hip arthroplasty (THA).
  • Previous literature reports both benefits and technical difficulties of converting fused hips to THA.

Purpose of the Study:

  • To review the single-surgeon experience of converting ankylosed hips to uncemented total hip arthroplasty.
  • To evaluate the clinical and radiological outcomes of this challenging procedure.

Main Methods:

  • Retrospective review of 5 uncemented THA cases for ankylosed hips (November 1991 - June 1996).
  • Minimum 3-year clinical and radiological follow-up.
  • Assessment of patient satisfaction and Harris Hip Scores.

Main Results:

Related Experiment Videos

  • Patients reported general satisfaction with the surgery.
  • Average Harris Hip Score improved from 62 preoperatively to 72 postoperatively.
  • Surgical outcomes were less satisfactory compared to routine THA.
  • Conclusions:

    • Uncemented THA for ankylosed hips can yield satisfactory outcomes with careful preoperative planning.
    • Restoration of leg length and abductor moment arm is crucial.
    • Modular prostheses offer surgical versatility in these complex cases.
