La distraction physaire dans les inégalités de longueur et déviations angulaires des membres

Chondrodiastasis has specific complications, mainly involving the distal femur (stiff knee, risk of septic arthritis). It provides rapid in situ correction resulting from epiphysiodesis bridges. The resection step proposed by Bollini is not necessary, but the growth plate is definitively sterilized. This implies that the procedure be used for preventive lengthening, depending on the predicted limb length discrepancy. This notion limits indications to older children. Besides the fact that several deformations can be corrected simultaneously, this technique does not require osteotomy and respects vascular supply to the regenerative tissue. It involves the physis responsible for the angular deformation or limb length discrepancy. It does not require internal fixation nor bone grafting and can be performed with weight bearing. Finally, the procedure can be adjusted as needed during the correction phase, with the patient in the standing position.
