查看更多>>摘要：Pre-contoured anatomical locking plates were designed to address the clinical need of fixing small epiphyseal segments with a larger number of screws.Those plates match the contour and shape of a variety of bones allowing for optimal buttress properties.The aim of this manuscript is to highlight the benefits of applying proximal humerus locking plates in the fixation of lower extremity bones.Although designed for the proximal humerus,the low-profile plate shape and anatomic contour also provides versatile use in certain areas of the lower extremity.This technical narrative highlights the versatile and reliable use of this plate for other anatomical areas than the one to which it has been originally conceived.
