Image Classification of Osteoporotic Vertebral Fracture with Endplate-disc Complex Injury

Abstract

Background The purpose of this study was to observe the condition of osteoporosis vertebral fracture(OVF) combined with endplate-disc complex (EDC) injury through MRI and CT, and to classify the degree of EDC injury according to the changes in the signal and morphology of the EDC on the image.Methods A total of 479 cases of OVF were included in this study. Baseline data were recorded. We investigate the incidence of EDC injury, observed the morphology and signal changes of EDC injury through MRI and CT, and divided it into grades 0-4 according to the severity of injury.We compared whether there were differences in the degree of EDC injury among different vertebral fractures, bone mineral density(BMD), and severity of vertebral fractures. Results Among 479 patients, 321 cases had EDC injury adjacent to fractured vertebral body. Among them, 158 cases were grade 0, 66 cases were grade 1, 72 cases were grade 2, 78 cases were grade 3, and 92 cases were grade 4. The degree of EDC injury combined with thoracolumbar vertebral fractures was more serious than that of thoracic and lumbar vertebral body fractures.Vertebral fractures with severe osteoporosis were combined with more severe EDC injury. The more severe the vertebral fracture, the more severe the combined EDC injury.Conclusion This study found that the incidence rate of EDC injury reached 67.0%. To patients with OVF, severe osteoporosis, and severe fractures in the thoracolumbar segments often have more severe EDC injury.

Preoperative planning of compact zone trajectory is necessary in treating osteoporotic vertebral compression fracture with endplate involvement: A prospective randomized controlled study

“…[8] According to previous report, the incidence rate of EDC injury reached 67.0% among patients with OVF. [9] Endplate integrity is critical in treating vertebral compression fracture. [10] One recent study emphasized the importance of distribution pattern of cement distribution between upper and lower endplates in these patients.…”
