Fig. 1From: A two-stage retrospective analysis to determine the effect of entry point on higher exit of proximal pins in lateral pinning of supracondylar humerus fracture in childrenSchematic representation of the exit zones of the proximal lateral pins. Line AB represents the upper border of the metaphyseal-diaphyseal junction (MDJ) region. Line CD is the inter-epicondylar line. − 1 to − 4 are exit zones below the upper border of the MDJ; + 1 to + 4 are exit zones above the upper border of the MDJBack to article page
