对年轻大鼠肱骨移植物的生长进行了研究，在肱骨干的近端或远端对骨膜进行周向分割。骨膜分离导致的骨骼比那些没有切开骨膜的骨骼更长。在近端分裂后，实验骨在两端比对照骨多生长30%，在远端分裂后近端多生长16%。然而，在骨膜远端分离后，实验骨和对照骨在远端的生长之间没有差异。实验组肱骨干骨膜下新骨沉积少于对照组。这些发现支持这样的观点，即骨膜是由于生长板的活动而处于张力下，并且骨膜张力的变化影响骨膜下骨的长度和沉积的生长。
The growth of transplants of young rat humeri has been studied following circumferential division of the periosteum at either the proximal or the distal end of the shaft. Periosteal division resulted in bones that were longer than those in which the periosteum was not cut. Following proximal division the experimental bones grew 30% more at both ends than the control bones and 16% more at the proximal end following distal division. There was, however, no difference between the growth of the experimental and control bones at the distal end following distal division of the periosteum. The experimental humeri had less new subperiosteal bone deposited over their diaphyses than the control humeri. These findings support the view that the periosteum is under tension as a result of the activity of the growth plates, and that changes in periosteal tension affect both the growth in length and the deposition of subperiosteal bone.
