Histomorphological study of the spinal growth plates from the convex side and the concave side in adolescent idiopathic scoliosis

Table 2 The proliferation potential indexes(PCNA indexes)(Mean ± SD) between the convex side and the concave side of the vertebral growth plate (%)

Locations		Upper end	Apex	Lower end
Resting zone	Convex side	2.78 ± 0.71	2.80 ± 0.71	2.69 ± 0.51
	Concave side	2.65 ± 0.56	2.77 ± 0.56	2.43 ± 0.76
Proliferative & Hypertrophic zone	Convex side	42.90 ± 11.46*	43.43 ± 5.47*	42.81 ± 3.10
	Concave side	39.17 ± 5.13*^#	25.63 ± 7.22*^#+	41.89 ± 3.27⁺

Note: * indicates statistical significant between convex side and concave side(P < 0.05);^# indicates statistical significant between upper end vertebrae and apex vertebrae(P < 0.05); ⁺indicates statistical significant between lower end vertebra and apex vertebrae(P < 0.05)
