Technical Advantages, Disadvantages, Risks, and Tips

Advantages	Disadvantages	Risks	Tips
Lighter assembly than circular fastener	Need for patient commitment to distraction	Inaccurate distraction can lead to consolidation or a lack of regeneration	If the osteotomy is consolidated, perform a new osteotomy. Compress the osteotomy and restart the distraction if the tissue does not regenerate due to distraction error.
Significant deformities can be corrected.	Need for care with pin dressing	Peroneal nerve neuropraxia	If neuropraxia occurs, start neuropathic pain medication.
Apply load on day 1 postoperative.	Fracture of the medial cortex of the osteotomy		If medial cortex fracture occurs, replace the self-centering apparatus and acutely reduce the residual deformity
A unique distractor facilitates patient understanding.
If overcorrection occurs, compress the osteotomy to the optimal point.
