THA (Fig. 1a). Three months later, she presented with a 6-week history of insidious onset of pain that worsened with prolonged ambulation. Plans were made to proceed with arthroplasty (Fig. 1b). The decision was made intraoperatively to obtain cultures and place an antibiotic spacer (Fig. 1c). The patient underwent insertion of a peripherally inserted central catheter and received 6 weeks of vancomycin. Her radiographs demonstrated well-ingrown components without any radiographic lucencies (Fig. 1d).

His initial radiographs showed bone loss of both the femoral head and acetabulum on the right side and the appearance of avascular necrosis on the left (Fig. 2a). Follow-up radiographs demonstrated that the patient's components were well fixed without evidence of lucency (Fig. 2c).

Radiographs at that time demonstrated right femoral head bone loss with associated acetabular bone loss and significant arthritis in the left hip (Fig. 3a). Radiographs at this time demonstrated good position of the right-sided implants; however, rapid dissolution of the left hip was noted (Fig. 3b).
