CHIVERS, DA; HILTON, TL and DIX-PEEK, SI. An assessment of the three-point index in predicting the redisplacement of distal radial fractures in children. SA orthop. j. [online]. 2013, vol.12, n.2, pp.18-22. ISSN 2309-8309.
BACKGROUND: Distal metaphyseal radial fractures are common in the paediatric population and their management is predominantly conservative. The incidence of redisplacement of these fractures is high and various methods have been described with the view to predict fracture redisplacement. One of these indices is the three-point index (TPI). METHODS: A retrospective review of 43 patients with distal radius fractures revealed that 19 patients suffered significant redis-placement at 2 weeks after closed manipulation in a plaster cast. RESULTS: The TPI index in the study was found to have a sensitivity of 84%, a specificity of 37%, a negative predictive value of 75% and a positive predictive value of 51%.: CONCLUSIONS: It was concluded that the TPI was a sensitive but not specific measure of fracture redisplacement and not practically applicable to influence management of these fractures and therefore not a useful tool in our clinical setting.
