RESUMEN
<p><b>OBJECTIVE</b>To compared the effect between early anatomical open reduction, internal fixation (ORIF) and closed reduction, internal fixation (CRIF) for treatment of children displaced femoral neck fracture.</p><p><b>METHODS</b>From March 2006 to May 2010,34 children with displaced femoral neck fractures were reviewed retrospectively. These patients were divided into two groups. Among them, 19 cases were treated by open reduction and internal fixation (ORIF) as group A, included 11 males and 8 females with an average age of (8.1 +/- 1.3), the other 15 cases were treated by closed reduction and internal fixation (CRIF) as group B, included 9 males and 6 females with an average age of (7.9 +/- 1.5). Complications were observed and the short term effectiveness was evaluated by Ratliff standard.</p><p><b>RESULTS</b>All children were followed-up from 1 to 3 years (means 1.2 years). All fractures were healed. There was statistical different in the curative effects between the two groups (Z=2.389, P= 0.017). The incidence of complications in two groups had statistical different (P=0.046).</p><p><b>CONCLUSION</b>The early ORIF could get better reduction with fewer complications than CRIF in fractures of the displaced femoral neck in children in Delbet type-II and type-III, therefore, ORIF should be considered.</p>
