Introduction Standards for treating idiopathic clubfoot are still under discussion. Over the last 10-15 years the Ponseti method has been widely accepted as the treatment of choice, but the method has been modified very often, and the original protocol is not always properly performed. A consensus group was set up in the UK in 2011 to define standards for Ponseti clubfoot treatment, and the purpose of our meeting is to extend these standards to the European level. Clubfoot experts from 12 countries met at Karolinska University in Stockholm to discuss goals, standards, challenges and treatment outcome, based on literature review and personal experience. Items discussed The ambitious agenda included most aspects of clubfoot treatment. Discussion following an intensive literature review was constructive, and the group was able to carry out discussions on defining the goal of clubfoot treatment and the preferred standard of treatment. Conclusion In order to establish the Ponseti method as the most effective treatment in the European context a methodological approach and analysis of existing literature remain crucial. Focus should hereby remain on defining outcome measures, the evaluation and comparison of all available methods over the long term and ease of implementation in the different healthcare environments across Europe.
Purpose The signs for clubfoot relapse are poorly defined in the literature and there is a lack of a scoring system that allows assessment of clubfeet in ambulatory children. The aim of this study is to develop an easy to use, reliable and validated evaluation tool for ambulatory children with a history of clubfoot. Methods A total of 52 feet (26 children, 41 clubfeet, 11 unaffected feet) were assessed. Three surgeons used the seven-item PBS Score to rate hindfoot varus, standing and walking supination, early heel rise, active/passive ankle dorsiflexion and subtalar abduction blinded to the other examiners. All parents answered the modified Roye score questionnaire prior to the clinical assessment. Correlation between the mean PBS Score and the Roye score was evaluated using Spearman’s rank correlation coefficient. Interobserver reliability was tested using weighted and unweighted Cohen’s Kappa coefficients. Results The Spearman’s rank correlation coefficient for correlation between mean PBS Score and Roye score was 0.73 (moderate to good correlation).The interobserver agreement for the total PBS Score resulted in an intraclass correlation coefficient of 0.93 (almost perfect agreement). Conclusion The PBS score is an easy to use, clinical assessment tool for walking age children with clubfoot deformity. It includes passive and active criteria with a very good interobserver reliability and moderate to good validity. Level of Evidence: Level I - Diagnostic study
