Comparison between percutaneous and open reduction for treating paediatric talar neck fractures

摘要

Abstract Background The purpose of the study was to introduce percutaneous reduction and fixation of paediatric talar neck fractures. The study also included a comparison between the technique and the conventional open surgery. Methods From October 2003 to May 2013, 23 children (group A) with closed two-part talar neck fractures were treated with percutaneous reduction. For comparison, another group of 26 children (group B) were treated with the conventional open surgery. A p value Results In group A, bone healing was achieved in all cases at a mean of eight?weeks. At the mean follow-up of 27?months, mean plantar flexion and dorsiflexion reached 96% of the opposite, normal, side. There were 20 excellent and three good results. In group B, bone healing occurred in 21 of 26 cases at a mean of 11?weeks. Nonunion was noted in five patients, among whom three were combined with avascular necrosis of the talar body. Mean follow-up was 29?months; mean plantar flexion and dorsiflexion reached 94% of the opposite normal side. There were 13 excellent, six good, two fair and five unsatisfactorily results. There were significant differences in the time to bone healing and in ankle-joint motion and function ( p ? Conclusions Percutaneous reduction is a successful technique for paediatric talar neck fractures. Compared with conventional open surgery, the mini-invasive procedure may produce rapid bone healing and better functional results. Level of evidence Therapeutic study, Level Ia (perspective study).
