摘要Introduction: Vertebral compression fractures (VCFs) are the most common among all osteoporotic fractures. The body may compensate to kyphosis from vertebral compression fractures (VF) with lordosis of the adjacent spinal segments, posterior tilting of the pelvis, hip extension, knee flexion and ankle dorsiflexion. However, the detailed influence of classical and novel sagittal parameters in VCF patients remains to be clearly documented.
Methods: In total, 142 patients with VCFs aged >60 years and 38 age-matched asymptomatic controls were prospectively enrolled. Whole-body sagittal alignment including thoracic kyphosis (TK), lumbar lordosis (LL), pelvic tilt (PT), pelvic incidence (PI), sagittal vertical axis (SVA), T1-pelvic angle (TPA), knee-flex angle and ankle-flex angle were measured. Quality of life was assessed with short-form 12 (SF-12), Oswestry Disability Index (ODI) and visual analogue scale (VAS).
Results: Despite presence of vertebral fracture, TK and LL showed no significant difference between two groups. However, PT and PI were found to be increased in VCF patients (p<0.001). TPA was significantly increased in VCF patients (p<0.001). All questionnaires (including SF12, ODI and VAS) showed poorer quality of life and increased pain in vertebral fracture group than those without (p<0.001).
Conclusion: Pelvic parameters are significantly worse in patients with vertebral collapse in elderly with VCF. In a previous younger cohort, spinal parameters were found to be worse in patients with VCF instead of pelvic parameters. This may be explained by the time needed for our body to accommodate to newly acquired deformities after osteoporosis related vertebral fractures.
