Summary
This study evaluated trapezium replacements for thumb arthritis, finding satisfactory pain relief and function. However, achieving stable implants remains a challenge, with potential causes discussed.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Biomaterials Science
Background:
- Pantrapezial disease and first carpometacarpal arthritis significantly impact thumb function and quality of life.
- Trapezium replacement is a surgical option for managing these conditions.
- Implant stability is crucial for long-term success in joint replacement surgery.
Purpose of the Study:
- To report early outcomes of total and partial trapezium replacements.
- To assess pain relief and functional recovery in patients undergoing trapezium replacement.
- To identify challenges related to implant stability and explore potential causes.
Main Methods:
- Review of early results from thirteen total trapezium replacements.
- Review of early results from seven partial trapezium replacements.
- Analysis of patient-reported pain and functional outcomes.
Main Results:
- Satisfactory pain relief was achieved in most patients.
- Good thumb function was observed post-surgery.
- Difficulty in achieving implant stability was a notable finding.
Conclusions:
- Trapezium replacement can provide effective pain relief and functional improvement for thumb arthritis.
- Implant stability is a key challenge in trapezium replacement surgery.
- Further research is needed to address and overcome implant instability issues.
