Acute L2 vertebral compression fracture sustained 2 months after surgery and treated with percutaneous VP. An 81-year-old female patient was diagnosed with L4 osteoporotic vertebral collapse (flat-type) and severe central canal and right central hugged lumbar disk herniation at L4-L5 underlying lumbar degenerative kyphosis. (A) Whole-spine lateral radiographic image (white dotted line: plum line). The patient simultaneously underwent (B) L4 percutaneous balloon kyphoplasty and (C) unilateral biportal endoscopic decompressive laminectomy. Sufficient neural decompression is seen on the magnetic resonance T2-weighted axial images (D) preoperatively, (E) immediately postoperatively, and (F) after 2 months postoperatively. Within the 2 months after surgery, she felt a significant improvement in pain and disability. Plain lateral radiographs (G) immediately postoperatively and (H) at 2 months postoperatively show acute L2 vertebral compression fracture, and (I) percutaneous vertebroplasty was performed on L2
