Summary
A novel monolateral external fixation technique for ankle joint compression-arthrodesis shows promising fusion rates and functional recovery in post-traumatic cases. This method offers a useful alternative for ankle fusion, with most patients experiencing pain relief and improved mobility.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Context:
- Ankle joint destruction often necessitates arthrodesis.
- Traditional arthrodesis methods can have limitations.
- External fixation offers adjustable compression and stability.
Purpose:
- To introduce and evaluate a new method of compression-arthrodesis of the ankle joint using monolateral external fixation.
- To assess the efficacy, complications, and functional outcomes of this technique.
Summary:
- A cohort of ten patients underwent ankle compression-arthrodesis with monolateral external fixation for post-traumatic joint destruction.
- The procedure involved bimalleolar incision, joint surface resection, and fixation with a Monofixateur.
- Bone fusion was achieved in 8-12 weeks, with a mean hospital stay of 17 days and early weight-bearing allowed.
Impact:
- Eight patients followed up showed significant pain relief and improved gait, with five rating the outcome as good.
- Complications included two pin-tract infections; one case had poor results due to screw penetration.
- The procedure resulted in a mean leg length discrepancy of 1 cm and preserved mean tarsal mobility of 23 degrees.
