A Case Report of U-Type Sacral Fracture After Chiropractic Adjustment

A U-type sacral fracture, or spinopelvic dissociation, resulting from chiropractic manipulation has not been described in the medical literature. This report presents the case of a 74-year-old male patient who sustained a U-type sacral fracture after drop-table chiropractic manipulation.

Our case demonstrates that chiropractic manipulative therapy involving the commonly used drop-table can cause severe injury. The patient's course was complicated by a delay in diagnosis and a prolonged hospital stay. Orthopaedic surgeons should have a high degree of suspicion for spinopelvic dissociation in the setting of bilateral sacral fractures. One year after injury, with conservative management, the patient returned to baseline function with mild residual neuropathy.
