Summary
This study shows the Acumed Hubcap circular plate is effective for four-corner carpal arthrodesis in wrist collapse. Patients reported good satisfaction and functional outcomes, with all achieving bone union.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Wrist Arthroscopy
Background:
- Four-corner carpal arthrodesis is a surgical procedure to fuse the carpal bones in the wrist.
- Scapholunate advanced collapse (SLAC) and scaphoid non-union advanced collapse (SNAC) are common causes of wrist arthritis and pain.
- Circular plates are used to stabilize the carpal bones during fusion.
Purpose of the Study:
- To evaluate the outcomes of four-corner carpal arthrodesis using the Acumed Hubcap circular plate.
- To assess functional outcomes, patient satisfaction, and radiological union in patients undergoing this procedure.
Main Methods:
- Retrospective review of eight patients who underwent eight four-corner carpal arthrodesis procedures using the Acumed Hubcap plate.
- Procedures were performed for scapholunate advanced collapse (five wrists) and scaphoid non-union advanced collapse (three wrists).
- Outcomes assessed included range of motion, quickDASH scores, visual analogue scores for satisfaction, and radiological union.
Main Results:
- All eight procedures achieved radiological union.
- Mean flexion-extension arc was 56°, and mean radial-ulnar deviation was 29°.
- Mean quickDASH score was 23/100, and mean patient satisfaction was 7.7/10 (77%).
- 87.5% of patients would recommend the procedure.
Conclusions:
- The Acumed Hubcap circular plate provides effective fixation for four-corner carpal arthrodesis.
- Functional outcomes and patient satisfaction are comparable to other circular plates.
- No non-unions were reported, which is a significant advantage over other fixation methods.
