[Severely displaced radial neck fractures after minimally invasive joystick reduction and Prévot nailing: long-term course in childhood].

Significantly displaced radial neck fractures in children are at risk for functional problems due to malaligned healing or growth disturbances at the proximal growth plate. Anatomic reduction is needed, especially in older children (aged 10+ years). Elastic stable intramedullary nailing (ESIN) (1993 Metaizeau) is the preferred method. When closed reduction is not possible, we use a joystick technique to fully reduce the radial head. The aim of this study was to challenge the hypothesis that this manipulation leads to secondary complications by affecting blood flow. Also, we asked the question to which extent an additional injury to the growth plate leads to functional problems concerning range of motion in the elbow joint. We undertook a retrospective analysis of children with severely displaced radial head fractures that occurred as isolated incidents or in combination with complex elbow fractures who had been treated by us with this technique between 1998 and 2004. We collected data on the clinical and radiological healing process.
