“…Clinically, the mechanical environment can be altered through increasing the amount of interfragmentary movement (IFM) by reducing the fixation stiffness of interlocked nails [2,4,[38][39][40][41][42] or external fixators [12,17,28]. The IFM is also influenced by the load on the operated leg due to gravity and muscle forces [7,14,20,36,43].…”

Background Dynamization involves a reduction in fixation construct stiffness during bone healing, allowing increased interfragmentary movement of the fracture through physiologic weightbearing and muscle contraction. Within some optimal range, interfragmentary movement stimulates healing, but this range likely varies across stages of bone healing. Questions/purposes How does the time of dynamization affect the cartilage formation, bony bridging, and bone resorption in a rat fracture-healing model? Methods Unilateral external fixators, stabilizing a 1-mm gap, were dynamized at 1 (D1 group, n = 10), 3 (D3 group, n = 11), or 4 (D4 group, n = 11) weeks postoperatively. Continuously 5 weeks stiff (S group, n = 10) and flexible (F group, n = 11) fixation were included for comparison. After 5 weeks, healing was evaluated by histomorphometric methods.

“…et al 1997.) 7 Intramedullary interlocking nailing has proved to be the effective method in the treatment of the complex fracture shaft of femur in adults. Since the femur is surrounded by muscles and excellent soft tissue coverage, the destruction of endosteal blood supply due to reaming does not impede the fracture healing.…”

Intramedullary interlocking nail is an effective treatment for tibial diaphyseal fracture. The contact between medullary rod and diaphyseal cortex is able to enhance fracture stability. However, how and to what degree the contact affects fracture healing and subsequent bone remodeling is still unclear. To investigate this, fracture healing and remodeling algorithms were combined, improved, and used to simulate the healing and remodeling processes in a transverse tibial diaphyseal fracture fixed with an intramedullary interlocking nail device. Two different diaphyseal fracture statuses, three different initial loading levels, and two nail materials were considered. The results showed that the medullary contact could significantly enhance the fixation stability; the strain reduction was up to 80% in the initial granulation callus. However, low initial loading level was found to be a more potential risk factor for the insufficient loading-induced nonunion other than medullary contact and stiffer nail material. Furthermore, the stabilizing effect of medullary contact diminished when stiff bone tissue formed in the callus; thus, the remodeling in the long-term was not affected by medullary contact.
