Histomorphometric Analysis of Callus Formation Stimulated by Axial Dynamisation in a Standardised Ovine Osteotomy Model

Table 4

nBV/TV and CgV/TV were assessed separately for the anterior and the posterior callus side. Although the absolute area of callus tissues is significantly different between the anterior and the posterior side, the relative amount of new bone within the anterior and the posterior callus area (nBV/TV) is very similar. Data are presented as mean values (mean), standard deviations (SD), median, minimum (Min), and maximum (Max) in %.
