Abstract

Objective: To describe the clinical and paraclinical characteristics of patients with thoractolumbar vertebral compression due to Kummell’s disease at Viet Duc University Hospital. Methods: A prospective descriptive study conducted on 27 patients with thoractolumbar vertebral compression due tho Kummell’s disease at Viet Duc University Hospital from January 2021 to January 2023. Results: Among the 27 patients in our study, the majority were female, accounting for 70.4%, with an average age of 58,6 ± 4,9 years. The clinical characteristics of the patients included an average VAS score of 7,4 ± 0,8, with 5 patients presenting with AIS D-level neurological injury, and an average ODI score of 67,2% ± 4,8%. On X-ray imaging: most patients had damage to a single vertebra (92,6%), with an average vertebral body compression angle of 29,2° ± 1,4°, and a regional kyphotic angle of 33,3° ± 1,8°, 100% of patients had intravertebral vacuum sign. The average T-score was 3,4 ± 0,5. On MRI: 77.8% of patients had vertebral body edema, 29.6% had spinal canal stenosis, and 18,5% had posterior ligamentous complex (PLC) injury, 100% of patients had intravertebral vacuum sign hyperintense on T2W and hypointense on T1W. Conclusion: The prominent clinical symptom of patients with vertebral compression due to Kummell's disease is spinal pain, which may be accompanied by neurological symptoms, primarily of mild to moderate severity. On X-rays, patients exhibit spinal kyphosis with an increased kyphotic angle and vertebral body collapse angle, along with a visible intravertebral vacuum sign. MRI may reveal damage to the posterior ligamentous complex (PLC), spinal cord edema, and a signal void within the vertebral body that appears hyperintense on T2W and hypointense on T1W.
