Purpose
To evaluate the complication rate of circular plate fixation in four-corner arthrodesis and compare outcomes to traditional fixation methods.
Methods
Retrospective chart review of 16 patients who underwent four-corner arthrodesis using the Spider Limited Wrist Fusion Plate. Patients were monitored clinically and radiographically for an average of 16 months.
Key Findings
- 56% of patients experienced complications.
- Specific complications included non-union (25%), dorsal impingement (25%), broken screws (13%), and others.
- The union rate was lower and complication rate higher than previously reported with other fixation methods.
Conclusion
Circular plate fixation for four-corner arthrodesis is associated with a high rate of complications and may not offer advantages over traditional techniques.
What This Means for Patients
Patients undergoing wrist fusion surgery should be aware of higher complication risks with circular plate devices and may benefit from alternative, more established fixation methods.
