Physeal effects of posterior VBT are not uniform throughout a multi-tether construct in the kyphotic swine model

Mean vertebral growth was not significantly inhibited by a posterior tether. Despite uniform tensioning throughout each construct, the most proximal tethered level experienced the most growth modulation indicating that growth may not be modulated the same at each level within a construct. Additionally, asymmetric vertebral growth may contribute to junctional kyphosis in the growing spine.
