Summary
Total elbow arthroplasty (TEA) implant modifications are common, especially in revision surgeries. While generally safe, these modifications carry a potential complication rate of at least 15%.
Area of Science:
- Orthopedic surgery
- Arthroplasty
- Biomedical engineering
Background:
- Implant modifications in total elbow arthroplasty (TEA) may be necessary for complex cases.
- Bone deformity and revision surgery are key indications for TEA implant modification.
- This study investigated the frequency and outcomes of TEA implant modifications.
Purpose of the Study:
- To determine the prevalence of implant modifications during TEA procedures.
- To assess the clinical outcomes and complication rates associated with modified TEA implants.
- To compare modification rates in primary versus revision TEA surgeries.
Main Methods:
- Retrospective review of 731 TEA procedures with intraoperative implant modification (1992-2019).
- Classification of complications as related or unrelated to implant modification by senior surgeons.
- International survey to assess the commonality of TEA implant modification practices.
Main Results:
- 13% of TEA procedures (94/731) involved implant modification in 84 patients.
- Modifications were more frequent in revision (21%) than primary (8%) TEA.
- Complications possibly or probably related to modification occurred in 15% of cases; no modifications led to implant failure.
Conclusions:
- Implant modification during TEA is not uncommon, particularly in revision cases.
- While not definitively linked to implant failure, modifications have an associated complication risk.
- Surgeons should carefully consider the necessity and potential risks of TEA implant modification.
