Continuous Local Antibiotic Perfusion (CLAP) for Post-operative Infection of Open Tibial Fractures: A Case Report.

INTRODUCTION

We encountered a case of post-operative infection of an open tibial fracture that was controlled by continuous local antibiotic perfusion (CLAP), a novel method of fracture-related infection (FRI) that we have developed. CLAP is a procedure in which a bone marrow needle and a double lumen tube are placed in the infected area, and an appropriate concentration of antimicrobial agent is continuously administered and perfused.

CASE REPORT

The patient was a 78-year-old woman. She was hit by a motor vehicle and fell to the farmyard floor. She suffered multiple traumas, including a lower leg open fracture, multiple rib fractures, clavicle fracture, pelvic fracture, mandibular fracture, and liver injury. Her tibial fracture was a Gustilo-Anderson type IIIA open fracture. After debridement and external fixation of the tibial open fracture on the same day, open reduction and internal fixation with an intramedullary nail was performed 3 days after the injury. Twelve days after the injury, local heat and redness were observed at the nail insertion wound and the posteromedial calf, and a purulent clot was discharged from the open wound. We performed curettage of the lesion and retained the implant. CLAP was then constructed to perfuse local antibiotics along the nail and large hematoma area. Locally, the inflammation improved and the inflammatory response became negative 3 weeks after the initiation of CLAP. Six months after surgery, bony union was achieved. At present, 3.5 years after the internal operation, there is no sign of infection, and the patient has returned to her pre-injury life with no abnormalities in motor function.

CONCLUSION

CLAP may be a novel treatment method that can be expected to achieve bone healing while preserving the implant in FRI cases after open tibial fracture.
