In primary closed and simple fractures the local bone healing type--primary or secondary bone healing--after internal fixation depends on the stability/rigidity which has been achieved and secured. This fact is not only of scientific interest but is also important and essential for a correct assessment of the postoperative clinical course. This is demonstrated and discussed by means of intramedullary nailing, which is an unstable osteosynthesis but which allows early loading.
在原发性闭合性单纯骨折中，内固定后局部骨愈合类型（一期或二期骨愈合）取决于所实现并确保的稳定性/坚固性。这一事实不仅具有科学研究价值，对于正确评估术后临床病程也至关重要。通过髓内钉固定术对此进行了说明和讨论，髓内钉固定术是一种不稳定的骨接合术，但允许早期负重。
