A case report of implanted bone displacement after abscess formation.

RATIONALE

Implanted bone is a commonly used filling material for bone defects, participating in the formation of new bone. Complications associated with implanted bone include nonunion, infection, etc. Few cases of implanted bone displacement through gravitational abscesses have been reported in the literature. This article aims to improve clinicians' recognition of this phenomenon and discuss preventive measures and treatment strategies for implant-associated infections.

PATIENT CONCERNS

A 7-year-old female patient was admitted to the hospital due to recurrent purulent fluid discharge from the incision site for 3 months following a right hip surgery 4 months ago. Wound secretion culture revealed a methicillin-resistant Staphylococcus aureus infection. The imaging before the first debridement in the external hospital showed that there were 2 high-density shadows around the right femoral greater trochanter, which were implanted bone.

DIAGNOSES

Implant-related infection and chronic osteomyelitis.

INTERVENTIONS

The implant and inflammatory lesions were removed through multiple surgeries and anti-infection treatment.

OUTCOMES

After 6 months of follow-up, there was no sign of infection in the wound.

LESSONS

It is rare-reported that implanted bone displacement is caused by factors such as abscess formation. Treatment and understanding of implanted bone around the greater trochanter of the right femur is important. Early recognition and surgical removal of displaced implanted bone play a crucial role in infection control and disease prognosis.
