A T-square apparatus that facilitates intra-operative applications of orthogonal alignment to spinal reconstruction. More specifically, at least one cross member is connected orthogonally to a longitudinal member to assist in aligning the hips and pelvis perpendicular to the longitudinal access of the spine and to assist in positioning of the shoulders parallel to the hips and perpendicular to the spine. The T-square apparatus includes radiopaque markers to allow more accurate estimation of this sometimes difficult to appreciate intra-operative alignment. |
