Lengthening of free fibular grafts for reconstruction of the residual leg length discrepancy.

BACKGROUND

We evaluated our results of lengthening of free vascularized fibular grafts using a unilateral external fixator in patients with residual leg length discrepancy after free vascularized fibular graft for lower limb reconstruction.

CASES PRESENTATION: Two patients were administrated to our hospital with residual tibial length discrepancy after vascularized free fibular graft surgery. Lengthening of the free vascularized fibular graft with a unilateral external fixator was performed to correct the leg length discrepancy. Both patients recovered well with no difficult in activities of daily living at the last follow-up.

CONCLUSIONS

This study shows that lengthening of free vascularized fibular grafts with an external fixator is an effective treatment for massive residual leg shortening after vascularized free fibular graft surgery.
