Summary
Custom glenoid implants offer a promising solution for significant bone loss during shoulder replacement surgery. These custom components improve patient outcomes and function in complex cases.
Area of Science:
- Orthopedic Surgery
- Biomaterials Engineering
- Radiology
Background:
- Massive bone loss in reverse total shoulder arthroplasty (RTSA) presents significant challenges in both primary and revision procedures.
- Custom glenoid implants have emerged as a potential solution for extensive glenoid bone destruction.
- Current usage is limited due to strict indications and the novelty of these custom components.
Purpose of the Study:
- To systematically review and analyze the existing literature on the clinical and radiological outcomes of custom glenoid implants in RTSA.
- To summarize the effectiveness of custom glenoid components in addressing bone loss during shoulder arthroplasty.
Main Methods:
- A systematic review was conducted following PRISMA guidelines.
- Databases searched included PubMed, Cochrane, and Livivo for relevant studies.
- Four studies encompassing 46 shoulders were included, reporting on clinical and radiological outcomes.
Main Results:
- The mean patient age was 68.8 years with a mean follow-up of 24.3 months.
- Significant improvements were observed in CMS (32.7 points) and ASES (39.8 points) scores.
- Positive radiological findings included increased anteversion (67.4 degrees) and abduction (51.9 degrees), with a reduction in VAS pain scores (5.4 points).
Conclusions:
- Custom-made glenoid implants represent a viable and effective option for managing large combined glenoid bone loss in RTSA.
- These implants demonstrate promising early results for both primary and revision shoulder arthroplasty settings.
- Further research and broader adoption may be warranted given the positive outcomes observed.
