The present application discloses methods for treating a multi-level spinal deformity. The methods may include inserting a tether in a minimally-invasive manner through an entrance incision. The tether is moved along the spine and positioned to reduce and/or eliminate the deformity. Once the tether is positioned along the spine, the tether may be secured to the vertebral members. In one embodiment, the tether includes a rigid section and a flexible section. The tether may be positioned within the spine with the rigid section extending along a first length of the spine and the flexible section extending along a second length of the spine. The different sections provide different corrective forces to the spine to reduce and/or eliminate the spinal deformity. In one embodiment, the rigid section extends along an apex of the spinal deformity.
