Summary

Radial head prostheses (RHP) aim to restore elbow stability and function after fracture. While effective, careful implantation and rehabilitation are crucial for good outcomes, especially in younger patients.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Radial head resection surgery can lead to complications.
  • Radial head prostheses (RHP) aim to replicate native radial head function for elbow stabilization and force transmission.
  • Current RHP strategies include loose fit stem, bipolar radial head, and anatomical radial head designs.

Purpose of the Study:

  • To review the role and outcomes of radial head prostheses in managing unfixable radial head fractures and elbow instability.
  • To highlight the importance of surgical technique and rehabilitation in minimizing complications.

Main Methods:

  • Literature review and analysis of personal experience regarding radial head prostheses.
  • Discussion of different RHP strategies and their associated challenges.
  • Emphasis on the necessity of a personalized postoperative rehabilitation program.

Main Results:

  • Radial head replacement is increasingly used for complex elbow injuries, despite potential complications.
  • Implantation technique and concurrent treatment of associated lesions are critical factors.
  • Positive clinical and radiographic results at 6-12 months suggest favorable medium- to long-term outcomes.

Conclusions:

  • Radial head prostheses offer a viable solution for specific elbow injuries, but complication rates are a concern.
  • Meticulous surgical technique and tailored rehabilitation are essential for successful outcomes.
  • Long-term success is anticipated if early clinical and radiographic results are positive, even in young patients.
