To examine the relationship between vertebral trabecular bone mineral density (tBMD), vertebral strength, and syndesmophytes in ankylosing spondylitis (AS) using quantitative computed tomography (QCT). Associations between syndesmophytes and vertebral density and strength in AS differ between bridged and non‐bridged vertebrae. Among non‐bridged vertebrae, low tBMD and strength are associated with syndesmophyte growth. Conversely, bridging is associated with subsequent large losses in tBMD, possibly due to mechanical off‐loading.
