INTRODUCTION: This study compared bone transport to acute shortening/lengthening in a series of infected tibial segmental defects from 3 to 10cm in length.
METHODS: In a retrospective comparative study 42 patients treated for infected tibial non-union with segmental bone loss measuring between 3 and 10cm were included. Group A was treated with bone transport and Group B with acute shortening/lengthening. All patients were treated by Ilizarov methods for gradual correction as bi-focal or tri-focal treatment; the treating surgeon selected either transport or acute shortening based on clinical considerations. The principle outcome measure was the external fixation index (EFI); secondary outcome measures included functional and bone results, and complication rates.
RESULTS: The mean size of the bone defect was 7cm in Group A, and 5.8cm in Group B. The mean time in external fixation in Group A was 12.5 months, and in Group B was 10.1 months. The external fixation index (EFI) measured 1.8 months/cm in Group A and 1.7 months/cm in Group B (P=0.09). Minor complications were 1.2 per patient in the transport group and 0.5 per patient in the acute shortening group (P=0.00002). Major complications were 1.0 per patient in the transport group versus 0.4 per patient in the acute shortening group (P=0.0003). Complications with permanent residual effects (sequelae) were 0.5 per patient in the transport group versus 0.3 per patient in the acute shortening group (P=0.28).
CONCLUSIONS: While both techniques demonstrated excellent results, acute shortening/lengthening demonstrated a lower rate of complications and a slightly better radiographic outcome. Bone grafting of the docking site was often required with both procedures.
LEVEL OF EVIDENCE: Level III; Retrospective comparative study.
