Distal radius fractures in children: substantial difference in stability between buckle and greenstick fractures

Background and purpose Numerous follow-up visits for wrist fractures in children are performed without therapeutic consequences. We investigated the degree to which the follow-up visits reveal complications and lead to change in management. The stability of greenstick and buckle fractures of the distal radius was assessed by comparing the lateral angulation radiographically

Predicting redisplacement after manipulation of paediatric distal radius fractures: the importance of cast moulding.

INTRODUCTION The majority of displaced distal radius fractures are managed by closed reduction and cast immobilisation. Redisplacement is associated with initial displacement, imperfect reduction and quality of cast. The aim of this study was to establish which factors predict the risk of redisplacement. MATERIALS AND METHODS A retrospective analysis between September 2010 and April 2013 of children who underwent closed manipulation and cast immobilisation for a distal third radius fracture was performed. Open fractures, those treated with fixation, and cases with associated dislocations or physeal injuries were excluded. Initial fracture translation and angulation, the distance from the physis and the presence of an ulna fracture were recorded. Intra-operative radiographs were analysed to assess reduction, the cast index and gap index. Clinic records and post-operative radiographs were reviewed to identify redisplacement or further surgical intervention. RESULTS During the study period, 107 children underwent closed reduction and casting: 82 boys (76.6 %) and 25 girls (23.4 %), and the mean age of the group was 10 years. Twenty-nine children (27 %) suffered a radiographic redisplacement although only five children underwent a second surgical intervention. Statistically significant risk factors for redisplacement were initial fracture translation (p < 0.001), success of reduction (p < 0.001) and associated ulna fracture (p = 0.021). Both the mean cast index (0.81 vs. 0.78) and mean gap index (0.16 vs. 0.14) were higher in the redisplaced group, but this did not reach statistical significance. CONCLUSION Closed reduction and immobilisation of paediatric distal radius fractures is associated with a high redisplacement rate. Initial fracture type and success of reduction are key risk factors

Distal metaphyseal radius fractures in children following closed reduction and casting: can loss of reduction be predicted?

PURPOSE: The aim of this study was to identify factors which contribute to loss of reduction (LOR). METHODS: Outpatient records and initial, post-reduction (PR) and follow-up radiographs of patients with a distal radial metaphyseal fracture were reviewed to determine demographic factors; fracture characteristics (obliquity, comminution, intact ulna); three-point cast index (3PI); and initial, PR, and follow-up displacement (angulation and translation in the sagittal and coronal planes). Univariate and multivariate regression were used to identify significant risk factors for LOR. RESULTS: A total of 161 patients were included in our series (119 boys and 42 girls). Fifty-seven (35%) patients met the criteria for LOR. Multivariate logistic regression revealed that patients over 14 years old were 4.8 times more likely (p = 0.01) to lose reduction, and those with more than 10% PR translation in the sagittal plane were four times more likely (p = 0.03) to lose reduction. In younger patients, initial coronal translation and PR sagittal translation were independent risk factors. Patients with over 10% initial translation in the coronal plane were 2.4 times more likely (p = 0.01) to lose reduction, and those with over 10% PR translation in the sagittal plane were 2.7 times more likely (p = 0.03) to lose reduction. Three point cast index was not found to be a significant risk factor (1.64 vs. 1.57, p = 0.43). CONCLUSION: Our study, the largest dedicated series of distal radial metaphyseal fractures, indicates that loss of reduction is common. Our analysis suggests that an anatomical reduction, which minimises residual translation, is the most important variable in preventing a loss of reduction
