A traction method and apparatus for treating irregularities in the lateral curvature and global posture of the thoraco-lumbar, lumbar, lumbo-pelvic and / or pelvic region of the spine involving the application of an intermittent transverse traction load to a region of the patient's body. The patient is placed in a supine or semi-supine position, and a traction sling is positioned about a region of the body of the patient, where the region of the body can be the thoracic region, lumbar region and pelvic region of the body. A transverse traction load having an intermittently varying magnitude is exerted on the sling to induce an extension posture in at least a portion of the spine of the patient and / or a flexion posture of the pelvic portion of the spine of the patient. The flexion and extension postures serve to at least partially restore normal lateral curvature of the thoraco-lumbo-pelvic region of the spine, thereby reducing lower back pain, correcting abnormal posture, and easing other symptoms that are related to thoraco-lumbo-pelvic spine curvature irregularities.

Individualized 3D printing method for thoracolumbar spine lateral approach interbody fusion cage
InactiveCN110384574AAvoid damagePrevent collapseAdditive manufacturing apparatusJoint implantsThree dimensional ctSpinal cage
The invention relates to the technical field of biomedicine, in particular to an individualized 3D printing method for a thoracolumbar spine lateral approach interbody fusion cage. The individualized3D printing method comprises the following steps that (1) three-dimensional CT scanning is conducted on a target part of a spine of a patient; and (2) three-dimensional CT scanning data are input intoa data workstation, corresponding intervertebral space three-dimensional stereoscopic structures completely matched with faces of upper and lower endplates of the target part of the spine of the patient are simulated, that is, the faces, the heights and the angles of the upper and lower endplates of the cage are determined. After being placed in the intervertebral space of the patient, the 3D printing interbody fusion cage is completely matched with or attached to the thoracolumbar spine intervertebral disc and the upper and lower endplates of the patient in a face-to-face mode, face-to-facesupporting between the cage and the end plates can be provided, thus damage and collapse of the end plates are avoided, sinking of the cage is avoided, stability is better, interbody fusion is facilitated accordingly, and the comfortable degree of the patient is increased.
