Summary

This study on uncemented CLS Spotorno femoral stems for total hip replacement shows a 96.7% survival rate and over 90% good functional scores. Further long-term follow-up is needed for comparison with cemented stems.

Area of Science:

  • Orthopedic surgery
  • Biomaterials science
  • Medical device engineering

Context:

  • Total hip replacement (THR) is a common procedure for hip osteoarthritis.
  • Uncemented femoral stems offer potential advantages over cemented stems, including bone ingrowth fixation.
  • The CLS Spotorno femoral stem is designed for uncemented fixation.

Purpose:

  • To evaluate the medium-term clinical and radiographic outcomes of uncemented CLS Spotorno femoral stems in total hip replacement.
  • To assess the survival rate, functional scores, and incidence of postoperative thigh pain.

Summary:

  • A review of 145 patients undergoing THR with CLS Spotorno stems (mean age 54.9 years, follow-up 7.8 years) was conducted.
  • Utilizing Merle d'Aubigne and Harris hip scores, along with plain radiographs, outcomes were assessed.

Related Experiment Videos

  • Results demonstrated a 96.7% survival rate and over 90% good functional outcomes, with minimal thigh pain (1 patient).

    • Impact:

    • The CLS Spotorno uncemented femoral stem shows promising medium-term results for total hip replacement.
    • These findings suggest a viable alternative to cemented stems, though longer-term data is required.
    • The low incidence of thigh pain is a notable positive outcome.
