title: Percutaneous drainage of subperiosteal abscess: a potential treatment for osteomyelitis.
abstract: OBJECTIVE
  Intravenous antibiotics and surgical drainage are the accepted methods of treating osteomyelitis complicated by abscess formation. The objective of this study was to determine whether percutaneous drainage of subperiosteal abscess is a potential treatment for osteomyelitis.
  
  
  METHODS
  Three pediatric patients with subperiosteal abscesses from acute osteomyelitis had percutaneous drainage with sonographic and fluoroscopic guidance using a Seldinger technique and an 8-F catheter.
  
  
  RESULTS
  Two patients required no further intervention and had the drainage catheter removed after 72 h. After completing a course of antibiotics they healed completely. One patient, after a week of purulent drainage, required open drainage including a bone debridement of an area of septic necrosis.
  
  
  CONCLUSIONS
  Percutaneous drainage of subperiosteal abscess may be an alternative to surgical drainage when medical therapy alone is inadequate. Development of intraosseous abscess, necrosis or persistent drainage suggests further intervention may be necessary.
