During growing rod treatment, the cervical sagittal balance changes in the patient without PJK. (It is a 10-year-old male patient diagnosed with idiopathic EOS. After the 2nd distraction, scoliosis and hyperkyphosis are corrected well. In the final follow-up, he does not have PJK above the growing rod. Sagittal cervical alignment change: C2-C7 CL increases from 57.9° to 62.9°, T1 slope increases from 48.1° to 57.4°, and C2-C7 SVA increases from 22.5 mm to 24.5 mm.)
