Instability in unlinked total elbow arthroplasties can be minimized with precise surgical techniques. Conversion to linked total elbow arthroplasty can salvage function in unstable cases.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Unlinked (unconstrained, resurfacing) total elbow arthroplasties (TEAs) face challenges with instability, limiting their clinical use.
  • True dislocation in unlinked TEAs occurs in less than 5% of patients.

Purpose of the Study:

  • To explore factors influencing instability in unlinked total elbow arthroplasties.
  • To discuss the management of unstable unlinked TEAs, including conversion to linked TEAs.

Main Methods:

  • Review of surgical techniques for unlinked total elbow arthroplasty.
  • Analysis of factors contributing to instability.
  • Discussion of conversion procedures from unlinked to linked total elbow arthroplasty.

Main Results:

Related Experiment Videos

  • Careful operative technique, including medial collateral ligament tensioning and lateral collateral ligament repair, may reduce dislocation risk.
  • Conversion to a linked total elbow arthroplasty is a viable salvage option for unstable unlinked TEAs.

    • Conclusions:

    • Optimizing surgical technique is crucial for improving the stability of unlinked total elbow arthroplasties.
    • Linked total elbow arthroplasty conversion offers a method to restore function after instability in unlinked implants.
