Abstract

Background: Bone and joint infections are common diseases in pediatrics. They still are a public health problem in Tunisia. The diagnosis is based on clinical, biological, radiological and skeletal scintigraphy arguments. The purpose of this study is to determine the contribution of triple phase bone scan in the exploration of musculoskeletal pain febrile child. Methods: This was a descriptive and retrospective study. It was conducted over a period of 5 years. It has interested all children explored in nuclear medicine department with suspected acute osteomyelitis (OMA) , osteoarthritis (OA) or septic arthritis (SA) referred from Orthopaedic Infantile service. All these patients had, alongside the conventional radiologic exams, a triple phase bone scan HMDP-Tc99m. Results: We collected 62 patients. Among the selected diagnoses, there were: 22 OMA, 4 OA, 4 SA. The mean age of the patients was 5.58 years with a male predominance. The main reason for consultation was pain. Fever was ≥ 38° C in 80 % of cases. The preferential localization was the lower limb (93.5 %). The quantitative and qualitative bone scan abnormalities objectified led to a correct diagnosis of: 18 OMA, 3 OA and 2 SA with a respectively estimated sensitivity and specificity of 76.6% and 90.6% in the all population. Conclusions: Bone scan demonstrates early abnormalities allowing osteoaricular infection diagnosis. It highlights the infection site, and draws a map of the lesions. Currently, imaging modalities differ in their availability, their cost, their input and diagnostic accuracy but they are complementary.
