Summary

As clinical and radiographic performance of an ultra-short anatomic cementless stem have been investigated only two randomized controlled studies, well-designed trials should aim for a thorough comparison of the outcomes of ultra-short and conventional cementless stems. The purpose of this study was to compare the outcomes of ultra-short and conventional stems in the same young patients who underwent simultaneous bilateral sequential total hip arthroplasties.

Conditions

  • Hip Replacement, Total
  • Osteonecrosis of Femoral Head
  • Coxarthrosis

Interventions

PROCEDURE

Total hip replacement

1. Simultaneous bilateral sequential total hip arthroplasties under the same anesthetic. 2. Randomization to treatment with an ultra-short or a convnetional cementless stem was accomplished with use of study numbers in sealed envelope, which were opened in the operating room before the skin incision was made. 3. The pore size was 250㎛. A 28-mm-diameter Biolox forte ceramic femoral head (CeramTec AG, Polchingen, Germany) ) was used in all hips. A cementless cup and a 28mm internal-diameter Biolox forte ceramic liner was used in all hips in both groups.
