Factors affecting early re-displacement of paediatric diaphyseal forearm fractures at Korle Bu Teaching Hospital
Abstract
Background: Complete fractures of the forearm have the potential to displace and angulate with overriding fracture fragments. Maintaining acceptable reduction is not always possible, and re- displacement or re-angulation is the most commonly reported complication. Factors responsible for the re-displacement after an initial acceptable reduction have not been clearly defined. The study aimed to determine the factors that influence early re-displacement of paediatric diaphyseal forearm fractures in Korle-Bu Teaching Hospital.
Methods: A prospective study in a cohort of 72 children below the age of 12 years with diaphyseal forearm fracture attending the Orthopaedic clinic were followed with close reduction casting from April 2017-December, 2017. Factors analysed included demographics, initial fracture features and the radiographic indices of the cast quality.
Results: 93.1% (67) of the fractures were because of the children falling on an outstretched arm. Majority of the children had a fracture of the distal 1/3 of the radius (n=38, 52.6%). The overall C.I was 0.8 (SD 0.1). The only significant predictor for predicting re-displacement was children falling on an outstretched hand (p-value=0.0).
Conclusion: This study has shown that the degree of initial displacement and the ability to achieve good reduction with a well moulded cast, constitute the major factors for early re-displacement of paediatric forearm fractures
