A novel intramedullary callus distraction system for the treatment of femoral bone defects

Abstract: An intramedullary device has some advantages over external fixation in callus distraction for bone defect reconstruction. There are difficulties controlling motorized intramedullary devices and monitoring the distraction rate which may lead to poor results. The aim of this study was to design a fully implantable and non-motorized simple distraction nail for the treatment of bone defects. The fully implantable device comprises a tube-in-tube system and a wire pulling mechanism for callus distraction. For the tr… Show more

“…In general, the thicker the skeleton, or the longer the TBS and transport distance, the greater the force [10][11][12][13]. Horas et al [4] used eight cadaveric thigh specimens to make a 60 mm bone defect at the middle femur, and then assessed the traction force required for 40-mm and 60-mm long of TBS using a novel type of intramedullary distraction system. The results showed that the traction force generated by soft tissue was linearly correlated with the transport distance.…”

“…Removal of external xator is usually performed after maturation of mineralization of the distracted callus and union of the docking site in traditional Ilizarov bone transport. However, traditional Ilizarov bone transport presented high rates of delayed union and nonunion of the docking site and pin-track infection or loosening, inconvenience for rehabilitation and nursing, and psychological disorder induced by long-term external xation [3][4][5][6]. These complications and drawbacks have become the bottleneck restricting the development of this technology.…”
