Reimplantation of an extruded osteoarticular segment of the femur: Case series and in vitro study in a rat model

Our study suggests that reimplantation of extruded osteoarticular segments of long bone may represent a feasible alternative to amputation. This is the first description of such a technique and its long-term outcomes in the clinical setting, which were corroborated with the outcomes of in vitro investigation in a rat model, concluding that contaminated extruded osteoarticular segments can be adequately sterilized for reimplantation by cleaning with povidone-iodine scrub followed by brief soaking in antibiotic solution. However, it remains unclear whether the antibacterial efficacy of different sterilizations noted in vitro is reflected in vivo, warranting further research.
