Why “progressive”?
The surgeon, after making an anamnesis, explains a surgical plan to the patient or his family.
When the surgical treatment is applied in inhalation general anesthesia enhances the elimination from 10 to 16 contractures in one surgery.
When applied in local one, from 4 to 6.
The period passing from a surgery to following one depends on the severity of the motor disease, presence of related pathologies and motor growth curve (when dealing with children).
