A previously healthy 42-year-old man presented with sudden onset back pain whilst playing football. A T8 vertebral fragility fracture was diagnosed following X-ray and MRI thoracic spine, which demonstrated grade 1 compression. In addition, osteopenia was reported on dual-energy X-ray absorptiometry scan (DXA), which revealed a T-score of -1.8 in the lumbar spine. A follow-up MRI carried out after 18 months, reviewed by the metabolic bone clinic (MBC)-radiology multidisciplinary team, suggested features compatible with a ruptured Schmorl's node. The DXA was re-reviewed by an MBC specialist and revealed bone density within expected range for age based on a Z-score above -2.0 using the ISCD 2023 recommended diagnostic criteria for men aged under 50. A conservative treatment approach was taken, sparing the patient from bisphosphonate therapy. This case highlights the importance of considering a ruptured Schmorl's node in the differential of vertebral compression, especially in younger patients with no risk factors, and assessing bone density using Z-score definition rather than T- scores.
一名42岁既往健康的男性在踢足球时突然出现背痛。胸椎X线和MRI检查后诊断为T8椎体脆性骨折，显示为1级压缩。此外，双能X线吸收法扫描（DXA）报告有骨质减少，腰椎T值为-1.8。18个月后进行了随访MRI检查，由代谢性骨病诊所（MBC）-放射学多学科团队进行评估，提示有符合Schmorl结节破裂的特征。MBC专家对DXA结果进行了重新评估，根据国际临床骨密度学会（ISCD）2023年推荐的50岁以下男性诊断标准，基于Z值高于-2.0，显示骨密度在该年龄的预期范围内。采取了保守治疗方法，使患者无需接受双膦酸盐治疗。该病例强调了在椎体压缩的鉴别诊断中考虑Schmorl结节破裂的重要性，特别是在无危险因素的年轻患者中，以及使用Z值定义而非T值来评估骨密度。
