44只兔在5周龄时进行手术；其中一组在右侧股骨髁间部分穿过生长板中央部分向上至骨干处钻一个2mm的孔，而另一组则钻一个类似的3.2 mm的孔。术后3周、6周、12周和24周，采用x线摄影、显微摄影、组织学和组织形态学技术对两股生长板标本进行分析。研究发现，生长板截面积的7%被破坏会造成永久性生长障碍和股骨短缩。
Forty-four rabbits were operated on when five weeks old; in one group a 2 mm drill-hole was made in the intercondylar portion of the right femur across the central portion of the growth plate up to the diaphysis, while in the other group a similar drill-hole of 3.2 mm was made. At 3, 6, 12 and 24 weeks after operation, specimens from the growth plates of both femora were analysed using radiographic, microradiographic, histological and histomorphometric techniques. It was found that destruction of 7% of the cross-sectional area of the growth plate caused permanent growth disturbance and shortening of the femur.
