Application and controversy concerning dynamization of interlocking intramedullary nails to facilitate healing of long bone fracture / 中华创伤骨科杂志

ABSTRACT

Controversy exists concerning clinical application of dynamization of interlocking intramedullary nails. Some scholars believe that dynamization of interlocking intramedullary nails is an effective therapy for delayed union and nonunion of long bones, the tibia and the femur in particular, because it may promote healing of long bones. However, some hold that the dynamization may detriment fracture healing because it deteriorates the instability of the fracture ends. It helps foster the rate of fracture healing and reduce complications to understand the impact of dynamization on fracture healing, proper timing of the dynamization, and rational application of the dynamization methods. This review expounds the research progress in dynamization mechanisms, optimal timing of the dynamization and controversy over the treatment strategies.
