Instability after resurfacing total elbow arthroplasty can occur due to ligament issues or surgical errors. Ligament reconstruction is recommended despite mixed results, as converting to a hinged implant later is difficult.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Reconstructive Surgery

Background:

  • Resurfacing total elbow arthroplasty can lead to instability.
  • Instability may stem from ligament insufficiency or surgical technique errors.
  • Current treatment options for instability have limitations.

Purpose of the Study:

  • To evaluate the challenges and potential benefits of ligament reconstruction in cases of resurfacing total elbow arthroplasty instability.
  • To discuss the difficulties associated with converting resurfacing implants to semiconstrained hinged implants.

Main Methods:

  • Review of clinical cases and surgical outcomes.
  • Analysis of factors contributing to instability in total elbow arthroplasty.
  • Discussion of ligament reconstruction techniques and their efficacy.

Main Results:

  • Ligament insufficiency and improper implant positioning are identified as key causes of instability.
  • Ligament reconstruction attempts, while yielding mixed results, are considered valuable.
  • Conversion from resurfacing to hinged implants presents significant surgical challenges.

Conclusions:

  • Addressing ligament integrity is crucial for stability in total elbow arthroplasty.
  • Ligament reconstruction should be considered despite variable outcomes.
  • Early intervention and appropriate surgical technique are vital to avoid complex revisions.
