ABSTRACT

[Objective]To study the techqiue and method of using in-situ replantation of dead bone to treat infected nonunion of femur. [Method] Debridement and removal of dead bone were carried out in 2 patients who had a chunk of dead bone and multiple sinus without involucrum formation.Sterilized sequester was replanted in-situ,tibia traction was performed and continual Kawashima's irrigation was applied with sensitive antibiotic after surgery.[Result]The time of bone healing in 1 case was ten months.The patient was followed up for 42 months,there was no recurrence of osteomyelitis.The time of bone healing in another case was about 12 months,he was followed up for 30 months,there was also no recurrence in this patient.[Conclusion]Traumatic osteomyelitis complicated with a massive sequester and nonunion could be cured by process which included debridement,in-situ replantation of sterilized death bone,continual washing as well as comprehesive treatment.It could achive the two primary purposes,inflammation cure and bone healing.Among these methods,improved Kawashima's irrigation is the most important method for inflammation cure and bone union.
