clinical presentation of vertebral osteomyelitis
localized LBP and tenderness, paravertebral muscle spasms, and radicular pain, extremity weakness causing SCI or nerve root compression
3
chronic osteomyelitis clinical presentation
pain for month, intermittent bone pain and tenderness, not as painful as acute osteomyelitis.

what are the three categories of the prosthetic joint infections
early less than 3 months post surgery
delayed 3-24 months
