Cervical Sagittal Imbalance after Cervical Laminoplasty in Elderly Patients

Table 3

Change in sagittal alignment parameters in patients after laminoplasty (1-year follow-up).

	All patients (60 cases)
	Preoperative	Postoperative
C2-7 SVA	2.20	3.16	0.96	<0.01
CL	13.28	13.54	0.25	0.758
T1 slope	25.79	28.47	2.68	<0.01
T1 slope-CL	13.06	15.96	2.90	<0.01

C2-7 SVA: C2-7 sagittal vertical axis; CL: cervical lordosis; T1 slope-CL: T1 slope minus cervical lordosis. . , statistically significant.
