To describe imaging characteristics of lumbar vertebrae compression fracture due to osteoporosis with indication for vertebroplasty on X-ray and magnetic resonance imaging. Subjects and research methods: Cross-sectional description, prospective study on 51 patients with lumbar vertebrae compression fracture due to osteoporosis with vertebroplasty at 103 Military Hospital from March 2023 until April 2024. Results: Most patients had 1 collapsed vertebra, accounting for 72.55%. The most common location of vertebral collapse is in L1, accounting for 39.39%. The majority of collapsed vertebrae were moderate (51.51%), wedge-shaped (59.09%), and had bone marrow edema on magnetic resonance (100%). Disc bulge and herniation are the most common combined injuries in patients with lumbar vertebrae collapse due to osteoporosis, accounting for 64.71%. The anterior wall, middle wall, and posterior wall heights were 17.93 ± 4.56, 16.89 ± 4.12, and 24.46 ± 3.85 mm, respectively. The indices of vertebral body collapse angle, Cobb angle and kyphosis angle are 13.58 ± 5.23, respectively; 10.93 ± 4.81 and 7.34 ± 3.26 degrees. Conclusion: Most patients have a collapsed vertebra, most commonly at the L1 position. Most of the moderately collapsed discs, wedge-shaped, have bone marrow edema on magnetic resonance and the most common combined lesions are disc bulges and herniations. The anterior wall, middle wall, and posterior wall heights were 17.93 ± 4.56, 16.89 ± 4.12, and 24.46 ± 3.85 mm, respectively. The indices of vertebral body collapse angle, Cobb angle and kyphosis angle are 13.58 ± 5.23, respectively; 10.93 ± 4.81 and 7.34 ± 3.26 degrees.
