Slotted fenestration combined with antibiotic cement intramedullary nailing in the treatment of chronic femoral osteomyelitis caused by Salmonella and Bacillus subtilis:a case report
Objective To introduce the cases of chronic femoral osteomyelitis caused by Salmonella and Bacillus subtilis and share the treatment methods.Methods A 53-year-old male patient was admitted due to redness and swelling pain in the right thigh with elevated body temperature for one week.The limited mobility was observed.A hard lump was palpable on the outer,anterior,and inner sides of the right thigh,with obvious tenderness.The X-ray film showed a large area of density change in the femur,with scallion-like changes in the medullary cavity and uneven thickness of the bone cortex.MRI showed large high signal areas in the femoral marrow cavity,ranging from the proximal femur to the upper part of the knee joint,with edema and abnormal high signal in the surrounding soft tissues of the femur.After relevant examinations,the patient underwent slotted fenestration combined with antibiotic cement intramedullary nailing.Results The patient's body temperature did not rise again after surgery.After routine dressing changes and a gradual decreased drainage flow from the incision,the drainage tube was removed and the internal end of the drainage tube was subjected to bacterial culture.The culture result was negative.The patient was discharge from the hospital when the wound healed and the suture was removed.The patient could walk with the assistance of an assistive device when discharged.Conclusions Grooved fenestration combined with antibiotic bone cement intramedullary nailing has good effects on osteomyelitis,along with complete debridement and low-risk bone strength reduction.
