Prevalence and risk factors of axial neck pain in patients undergoing multilevel anterior cervical decompression with fusion surgery

Table 3 Comparison of C2–7 Cobb angle between the patients presenting preoperative kyphosis in the two groups

	Preoperative kyphosis		P value
	Axial pain (n = 11)	No axial pain (n = 14)	P value
Angle of C2–7 (°)	− 12.65 ± 3.09	− 7.05 ± 1.64	< 0.001
Correction range for kyphosis (°)	20.07 ± 3.99	12.57 ± 3.65	< 0.001

For all the patients with preoperative cervical kyphosis, the axial neck group was significantly more likely to exist a higher preoperative angle of C2–7 (P < 0.001) and a higher correction range for kyphosis (P < 0.001)
