One of the most important causes of residual damage in skeleton is incompletely treated osteoarticular infections (OAI).
Goal:
to assess the value of emergency three-phase bone scan (3FBS) in the evaluation of OAI.Methods:
Thirty-eight children were studied with 54 3FBS.Results:
Global analysis: 76% of the cases were principally articular; staphylococcus germs and hip's affection were the common. Nine patients with preoperative scan were positive with 16 foci, 86% confirmed by surgery cultivate. Seven children had negative 3FBS without posterior clinical symptomatology; in 5 of them it was demonstrated soft tissue involvement with normal osteoblastic phase. In 14/17 cases evaluated after surgical intervention, there was a relation between the scan and the clinical course. In two of those cases, in the 3FBS a new location was found.Conclusion:
3FBS is a helpful tool in the diagnosis and assessment of acute OAI in pediatric population. A positive 3FBS is highly accurate for OAI and a negative one rules it out securely.
La principal causa de daño esquelético residual son las infecciones osteoarticulares (IOA) con un tratamiento inadecuado.
