Abstract
Corticotomy is an essential procedure for deformity correction and there are many techniques described. However there is no proper classification of the fracture pattern resulting from corticotomies to enable any studies to be conducted. We performed a retrospective study of corticotomy fracture patterns in 44 patients (34 tibias and 10 femurs) performed for various indications. We identified four distinct fracture patterns, Type I through IV classification based on the fracture propagation following percutaneous corticotomy. Type I transverse fracture, Type II transverse fracture with a winglet, Type III presence of butterfly fragment and Type IV fracture propagation to a fixation point. No significant correlation was noted between the fracture pattern and the underlying pathology or region of corticotomy.
Highlights
Distraction osteogenesis is a procedure in which a bone is fractured and gradually distracted to allow correction of deformity or lengthening of the bone
In some cases the whole extent of corticotomy could only be observed following some amount of lengthening
Type III is a transverse corticotomy with a “butterfly” fragment / both proximal and distal extension (Fig. 1C)
Summary
Distraction osteogenesis is a procedure in which a bone is fractured and gradually distracted to allow correction of deformity or lengthening of the bone. The procedure allows preservation of blood supply to the bone ends, and improves the quality of new bone formation[3] As first described by Gavriil Ilizarov the technique of corticotomy involves the use of an osteotome to divide the anterior, lateral and medial cortices, while the posterior cortex is broken by rotational force 4. De Bastiani later improved on this technique with the use of multiple drill holes connected with an osteotome to complete the corticotomy 1. Both techniques have been shown to yield similar results in terms of bone regenerative quality and time to union and consolidation 5
