Purpose
To assess the complication rates associated with circular plate fixation (Spider Limited Wrist Fusion Plate) in four-corner arthrodesis and compare outcomes to traditional fixation methods.
Methods
Retrospective review of 16 patients treated with circular plate fixation, followed clinically and radiographically for an average of 16 months.
Key Findings
- 56% complication rate observed.
- Complications included non-union (25%), dorsal impingement (25%), and screw breakage (13%).
- Union rates were lower, and complication rates higher than with traditional fixation techniques.
Conclusion
Circular plate fixation in four-corner arthrodesis is associated with a high rate of complications and may not provide advantages over conventional methods.
What Does This Mean for Providers?
Exercise caution when selecting circular plate fixation for four-corner arthrodesis. Consider traditional fixation methods given their comparatively lower complication rates and higher union success.
