A case of a Chance fracture through an instrumented pedicle is presented. The radiographic and intraoperative findings and management of this complication are reported.
To increase awareness of the complications of transpedicular screw fixation and to suggest a form of management of this unusual complication.
To the authors' knowledge, this is the first reported case of such a vertebral fracture occurring after pedicle screw fixation.
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.
Surgical intervention, including fracture reduction and extension of the instrumented fusion to the pelvis, provided effective restoration of physiologic sagittal alignment.
Chance fracture after pedicle screw fixation can be successfully managed with surgical intervention.

提高对经椎弓根螺钉固定并发症的认识，并提出对这种罕见并发症的一种处理方式。
据作者所知，这是首次报道的椎弓根螺钉固定术后发生此类椎体骨折的病例。
一名患有手足徐动型脑瘫且胸椎后凸进行性加重的44岁男性，在节段性器械固定结构的尾端发生了Chance骨折。
手术干预，包括骨折复位以及将器械融合范围扩展至骨盆，有效恢复了生理矢状位对线。
经椎弓根螺钉固定术后的Chance骨折可通过手术干预成功处理。
