Delayed Infection in a Patient After Total Hip Arthroplasty.

A 67-year-old woman presented 3 weeks following left total hip arthroplasty (THA) and received 12 physical therapy sessions over 2 months. One week after returning to work, the patient experienced severe left buttock pain and was diagnosed with degenerative L5-S1 spondylolisthesis and foraminal stenosis, for which she subsequently underwent L5-S1 laminectomy and fusion. She returned to physical therapy 2 weeks later and was referred back to the physician, who ordered radiographs that showed medial migration of the hip components. In addition, joint cultures were positive for the bacteria Parvimonas micra. The patient had a revision THA and was treated for the infection.
