The collarless, smooth, polished, tapered stem shows good long-term radiographic results, supporting its continued use in total hip arthroplasty. Future designs with interchangeable heads may help manage polythene wear, a significant long-term challenge.

Area of Science:

  • Orthopedic surgery
  • Biomaterials science
  • Radiology

Background:

  • Total hip arthroplasty (THA) is a common procedure to address hip joint degeneration.
  • Long-term implant survival is crucial for patient outcomes.
  • Polythene wear is a known mode of failure in THA.

Purpose of the Study:

  • To evaluate the long-term radiographic outcomes of a specific collarless, smooth, polished, tapered femoral stem.
  • To discuss the potential of future implant designs with interchangeable heads to mitigate polythene wear.

Main Methods:

  • Review of radiographic appearances of patients with the specified femoral stem.
  • Analysis of potential solutions for long-term implant challenges.

Main Results:

  • The collarless, smooth, polished, tapered stem demonstrated satisfactory long-term radiographic appearances.
  • The design encourages continued clinical use based on current evidence.

Conclusions:

  • The evaluated femoral stem design is suitable for long-term implantation.
  • Interchangeable heads in future THA designs could provide a solution for managing polythene wear.
