Corrective osteotomy : synostosis
When bones are fused together, a corrective osteotomy can be performed, restoring the good functioning of the articulation.
This synostosis surgery requires high precision in order to separate the bones to the appropriate depth on the one hand, and to maintain the healthy articulation on the other hand.
A surgical guide helps the surgeon to resect coalescent bones. It controls the shape of the resection (depth, length and thickness) with a high precision and accuracy.
