Table 2 Histomorphometric analysis of the iliac cartilage of IS and control subjects (expressed as median (minimum, maximum))

From: Accelerated endochondral growth in adolescents with idiopathic scoliosis: a preliminary histomorphometric study

  HZ thickness (μm) Area of cell-nest in HZ (μm2) Number of HC (/cell-nest) Number of PC (/microscope)
IS (Risser = 0) 270.8(196.9, 318.0) 6566.8(3009.9, 10306.7) 14.2(8.0, 16.6) 111.8(79.0, 202.0)
Control (Risser = 0) 226.6(91.0, 328.4)* 5433.2(1850.7, 19223.0)* 10.1(5.3, 13.1)* 86.6(67.0, 131.0)*
IS (Risser = 2) 182.8(134.0, 310.0) 4721.1(2347.0, 13006.0) 9.0 (6.4, 14.8) 80.7(67.0, 110.0)

  1. HZ: hypertrophic zone; HC: chondrocytes in hypertrophic zone; PC: chondrocytes in the proliferative zone; IS: idiopathic scoliosis.
  2. The Mann–Whitney U test were used to compare IS and control subjects, *:P < 0.05.
