Comparison Between the Clinical Effect of Percutaneous Kyphoplasty for Osteoporosis Vertebral Compression Fracture Patient with or Without Sarcopenia: A Retrospective Cohort Study

Figures & data

Figure 1 An 84-year OVCF female patient with sarcopenia treated with PKP. (A) the CT scan at the level of third lumbar vertebrae, (B–D) the preoperative X-ray and CT-scan showed L1 compression fracture, and the AH is 66.1%, LKA is 16.4°(Red arrows: Cobb angle between the superior and inferior aspect of the fractured vertebra). (E and F) the post-operative CT scan showed the post-operative AH is 93.1% and LKA is 6.3°.
