case_images: A plain radiograph revealed cervical degenerative kyphoscoliosis with ossification of the anterior longitudinal ligament (Figure 1). Plain lateral radiography in standing position 4 months after surgery revealed improvement of sagittal balance and pelvic tilt compared to preoperative results (preoperative C7 plumb line -85.1 mm   postoperative C7 plumbline -11.7 mm, preoperative pelvic tilt 22    postoperative pelvic tilt 14 ), with significant improvement in overall spinal alignment (Figures 1, 2).

case_images: Histological examination. (A) H.E. staining of trapezius muscle, showing myogenic atrophy. (B) H.E. staining of sternohyoid muscle, showing normal pattern.
