Management of olliers disease and its complications: 11 years prospective study of a case report

7 yr old male child presented to us for shortening of left lower limb by 2 cm with mild pain thigh and leg before 11yrs. We followed him till today.on investigation and biopsy from tibia found multiple enchondromas even in opposit lower limb but not much significant symptomatic. 4 yrs later pt developed pathological fracture in lower end left femur treated surgically .at the onset of growth spurt pt developed limb length discrepancy and varus angular deformity at left knee.pt underwent corrective surgery in the form of partial epiphyseal growth arrest surgery and limb lengthening surgery for tibia as its contribution in shortening was more ,by rail Road fixation and corticotomy at proximal end . Though literature advocates ring fixator but we found it more convenient. at the end of 9 months we achieved our goal. 15.6 degree of varus was reduced to 6 degree and was compensated at valgus of 6 degrees. Even after 4 ½ yrs of last surgery patient is doing very well.
