Abstract

Objective

To find out frequency of bony union and postoperative complications with segment transport by Ilizarov in patients with congenital pseudoarthrosis of the tibia (CPT).

Study design

Descriptive case series.

Place & Duration of study

Department of Orthopedics, Bahawal Victoria Hospital, Bahawalpur, from June 2009 to December 2016.

Methodology

In all patients osteotomy was done and Ilizarov fixator applied for bifocal technique of segment transport. Variables under consideration were leg length discrepancy, associated neurofibromatosis, postoperative hospital stay, bony union, postoperative complications and patients’ compliance and patient/attendant satisfaction.

Results

Ilizarov external fixator was applied to all seven patients after generous excision of the sclerosed bone (2.5 - 4cm) with thorough debridement of surrounding periosteum.  Consolidation (clinical and radiological) was achieved in average 5.86 weeks. Illizarov fixator was removed followed by application plaster cast for further six weeks.  All patients showed bone union. There was no case of re-fracture, nonunion and residual leg deformity during average follow up of two years.

Conclusion

Ilizarov fixation not only preserved local circulation, produced adequate compression but also covered the bone loss by segment transport resulting in bone union in all cases.
