title: Multi slice computed tomography approach in the assessment of supracondylar humeral fractures in children.
abstract: The purpose of this study was to assess the impact of Multi Slice Computed Tomography (MSCT) on the understanding of the spatial displacement of supracondylar humeral (SCH) fractures, their classification and their management. A prospective study was conducted on 63 children with SCH fractures Gartland II or Lagrange 2 and 3, over a period of 30 months. The patients were 42 boys and 21 girls, aged between 3 and 14. All patients were imaged using conventional radiography. Thirty-two patients underwent MSCT and 3-dimensional reconstructions. According to the Lagrange classification system, 16 patients had type 2 fractures and 47 had type 3 fractures. In type 2, the posterior cortices of both medial and lateral columns were bent on CT (n = 6). In type 3, CT-scan made it possible to distinguish two subgroups. In the first subgroup (n = 12) there was fracture of both anterior and posterior cortices of the lateral column; however, the posterior cortical surface of the medial column was preserved. In the second subgroup (n = 14), there was no cortical surface contact in the medial column, but the continuity of the posterior cortical surface of the lateral column was preserved. Based on a new concept of column stability, the use of CT-scan has allowed for a better understanding of supracondylar fractures in children.
