Case:
A 20-year-old man with Noonan syndrome had rigid cervical kyphosis caused by cervical myelopathy and thoracic lordosis caused by pulmonary disfunction. Two-staged corrective surgery, which involved initial posterior spinal fusion (PSF) in T2-L2 followed by PSF in C3-T2, had been performed without any complications. The radiographs before surgery and 2 years after surgery showed that cervical lordosis (C2-7) changed form -56° to -29°, and thoracic kyphosis (T5-12) improved from -49° to 10°.
Conclusion:
Initial realignment surgery in the caudal lesion should be better for improving global spinal alignment in patients with rigid spinal deformities at different locations.
