【摘要】 交锁髓内钉作为四肢管状骨骨折治疗的主流器械,使用方法有动力性固定和静力性固定,前者骨折端应力遮挡效应小,但稳定性差,后者恰相反。所以临床上常选用交锁髓内钉静力性固定作为手术常规。因应力遮挡造成的各种并发症时常发生,本文意在阐明微动与骨折愈合的关系,并且展望一种具有微动功能的交锁髓内钉。更多还原

【Abstract】 As a main treatment instrument of limb fractures, the interlocking nail is used in two ways: dynamic fixation and static fixation. The former has less stress shielding but lower satiability. The latter is just the opposite. Therefore, static fixation is the main choice in clinic. But because of the higher stress shielding, complications take place frequently. This article is to discuss the relationship between micromovement and fracture healing, and calls for a new kind of interlocking nail which has micromovement function.更多还原
