摘要： The method according the the invention comprises the following steps: a) taking a sagittal preoperative x-ray of the vertebral column of the patient to be treated, extending from the cervical vertebrae to the femoral heads; b) on that x-ray, identifying the pelvic parameters, the lumbar lordosis, the position of the apical lumbar vertebra, distances called SVA and SFD and a cloud of points; c) deducing, among predetermined morphotypes, the morphotype to which the treated vertebral column corresponds and deducing therefrom the desired postoperative apex point; d) positioning the different points of the cloud of points in a reference centered at the plate of S1; e) simulating the correction to be applied to the lumbar segment to be treated, by defining co-radial arcs situated below and above the desired postoperative apex point; defining two arcs concentric to the two curvatures obtained, which are tangent to each other at the apex point; f) translating these arcs away from the mean line of the vertebral column and defining a two- or three-dimensional model of the rod to be implanted, curved along the arcs.

摘要： The implant (1) includes at least two assembled components, at least a first component (3) is intended to be movable relative to at least a second component (2). The method includes the steps of: designing the implant (1) such that the second component (2) at least partially envelops the first component (3) and that at least one connecting bridge (4) connects the first component to the second component, each bridge (4) having a section such that it is frangible; making the implant (1) using a so-called “3D printing” method, includes depositing on a platen, a layer of powdered fusible material, causing the particles of this layer of powder to fuse in locations corresponding to the shape which, at this layer, the first component (3, 23, 33, 53, 63) and/or the second component (2, 22, 32, 52, 62) and/or the at least one bridge (4, 24, 54, 64) have, depending on whether the first component, the second component and/or said bridge are present at the section the implant to be formed has at the layer; repeating these operations until the implant (1, 21, 31, 51, 61) is fully constructed, and eliminating the powder particles that are not fused.
