Schmorl's nodes and vertebral fractures: A diagnostic dilemma

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.
