Lengthening z-osteotomy of the fibula to correct persistent talar shift following open reduction internal fixation of ankle fractures.

BACKGROUND

In cases where ankle fracture union has been compromised by persistent syndesmotic diastasis following open reduction internal fixation, both external rotation and shortening of the fibula have been identified as prominent features.

OBJECTIVE

This study reports a technique that uses a z-osteotomy to achieve both lengthening and internal rotation of the fibula to correct persistent talar shift following ankle fracture fixation.

METHODS

Four patients with persistent talar shift following open reduction internal fixation for an ankle fracture received z-osteotomy of the fibula to achieve both lengthening and internal rotation.

RESULTS

At the latest clinic review, all 4 ankles exhibited satisfactory clinical and radiological union. All patients have returned to full mobility and are satisfied with the outcome.

CONCLUSIONS

This study demonstrates the effectiveness of lengthening z-osteotomy of the fibula in correcting persistent talar shift following internal fixation of ankle fractures.

LEVEL OF EVIDENCE: Therapeutic Level V.
