The clinical outcome of patients with ankylosing spinal disorders (ASDs) sustaining a spinal fracture has been described to be worse compared with the general trauma population. ⋯ Many patients with AS and DISH showed unstable (hyperextension) fracture configurations and neurologic deficits. Complication and mortality rates were higher in patients with ASD compared with control patients. Increasing age and presence of DISH are predictors of mortality after a spinal fracture.

Primary malignant tumors of the sacrum are rare. Chondrosarcoma is one of the common malignant tumors arising from the sacrum. Chondrosarcoma is often invasive, and there is a high propensity for local recurrence. Surgical resection is often the only effective treatment; however, the treatment of malignant sacral tumors can be challenging, both because of the anatomy of the spinopelvic complex and the frequently large tumor size. ⋯ The advantages of our method include the availability of high dose of radiation because of extracorporeal irradiation, excellent fit between graft and host bone, reduction of the dead space, no immunological rejection, no need for a bone bank, availability of the sacrum not only for the augmentation of the large defect but also for the scaffold for the other bone grafts. Our report is of only one case; however, we consider that it could be one option for the treatment of sacral malignant bone tumors, such as chondrosarcoma.

Despite the frequency with which surgeons perform posterior spinal surgery and the precautions against wrong-site surgery, operations on incorrect levels still occur. Wrong-level exposure is documented in 0.32% to 15% of cases. Additionally, there is little consensus as to what is the most accurate method for localizing the correct spinal level. ⋯ Despite the variety of localization modalities, most surgeons use only a few. Whereas wrong-level localization is relatively rare, the ideal frequency is never. There is no standard approach that will entirely eliminate these mistakes; however, using a localization time out and increasing awareness of common sources of error may help decrease the incidence of wrong-level spine surgery.
