STUDY DESIGN: A case of a Chance fracture through an instrumented pedicle is presented. The radiographic and intraoperative findings and management of this complication are reported. OBJECTIVE: To increase awareness of the complications of transpedicular screw fixation and to suggest a form of management of this unusual complication. SUMMARY OF BACKGROUND DATA: To the authors' knowledge, this is the first reported case of such a vertebral fracture occurring after pedicle screw fixation. METHODS: A 44-year-old man with athetoid cerebral palsy and a progressive thoracic kyphosis sustained a Chance fracture at the caudal end of the segmental instrumentation construct. RESULTS: Surgical intervention, including fracture reduction and extension of the instrumented fusion to the pelvis, provided effective restoration of physiologic sagittal alignment. CONCLUSION: Chance fracture after pedicle screw fixation can be successfully managed with surgical intervention.
