CORRECTION OF ADOLESCENT BLOUNT`S DISEASE DEFORMITY USING ILIZAROV FRAME A CASE REPORT.

Abstract

Introduction- Blount's disease is dened as a growth disorder of medial aspect of proximal tibia physis with abrupt medial angulation of proximal tibia distal to epiphysis, leading to varus angulation of proximal tibia and medial rotation of tibia. Epidemiology is not well established and very rarely cases have been reported from Indian subcontinent. It is associated with internal tibial torsion and genu recurvatum. The aim of Objective: this work to evaluate the results of acute correction of adolescent Blount's disease using ilizarov frame constructed for gradual correction taking the benets of acute correction. A 16 year old male adolescent presented with Presentation Of Case- deformity in right foot and altered walking pattern for past 2 years . On examination there was 13 degrees varus deformity in right leg. There was a 15 degree internal tibial rotation on right side. Knee range of motion was 10 degree of hyperextention to 140 degree of full exion. Patient managed by surgical intervention. oblique proximal osteotomy was done. deformity correction was done by ilizarov frame. patient recovered well with correction of deformity and could walk with normal gait pattern. Patient result were assessed both cli Results- nically and radiological .Restoration of mechanical axis ,knee range of movement, weight bearing, range of motion [ROM] external xator time and possible complications were assessed. The average external xator time was 12 weeks. Blount's disease is a very rarely encountered condition in Conclusion- Indian subcontinent but has a characteristic presentation. We conclude that acute correction of adolescent Blount`s disease using a frame constructed for gradual correction is a safe and reliable technique. It combines the benets of both acute and gradual correction allowing for shorter healing time and to correct any operative error at the clinic and reducing the need for intraoperative uoroscopy.
