STUDY DESIGN: Twelve spontaneously occurring fractures of the spin in nine skeletally immature animals were investigated.
OBJECTIVES: These fractures were analyzed radiographically, morphologically, and histologically.
SUMMARY OF BACKGROUND DATA: The most commonly injured regions were the cervical and lumbar regions. Multiple-level fractures were noted in three specimens.
METHODS: Morphologic and histologic examination invariably detected fractures in cases of spinal cord injury without radiographic abnormality.
RESULTS: The end-plate physes and synchondroses were found to be the "weak links" for propagation of fractures. Radiographically benign-appearing ring apophyseal fractures were found histologically to propagate from the end-plate physis through the vertebral body via the contiguous neurocentral synchondroses.
CONCLUSIONS: The observed morphologic and histologic fracture patterns should provide a better understanding of the probable comparable pathoanatomy of spine and spinal cord injuries in children.
