Problems solved by technology

[0011] However, it is difficult for the surgeon to determine the optimal configuration of the optimal fusion cage or prosthesis based only on experience and specific biometric data he obtains from the relevant spinal segment, for example using medical imaging techniques

Embodiment Construction

[0120] 1 Introduction

[0121] figure 1 is a side view of a human spine containing vertebrae 12 and intervertebral discs 14 disposed in intervertebral disc cavities formed between adjacent vertebrae 12 . The first seven vertebrae 12 counted from the top of the spine 10 form the cervical spine 16 , the next twelve vertebrae form the thoracic spine 18 and the remaining five vertebrae 12 form the lumbar spine 19 . The latter is connected to the pelvis by the sacrum S. The cervical and lumbar spine 16, 19 have a lordotic curvature, while the thoracic spine 18 has a kyphotic curvature. according to figure 1 Clearly, vertebrae 12 and intervertebral discs 14 have different shapes and sizes. This in turn causes different curvatures and different mobility of the spinal segments. The joints formed by pairs of adjacent vertebrae 12 then have significantly different properties along the spine.

Abstract

A computer program for spine mobility simulation is configured, if running on a computer, to cause the computer to perform the following steps: a) accessing biometric data which relate to the spine of a patient, the spine having at least one compromised spine segment; b) displaying a model of the spine of the patient comprising a plurality of vertebrae; c) enabling a user to change the position of at least one of the vertebrae of the spine model; d) computing the effects of the position change on the remaining vertebrae; e) displaying the spine model in a new configuration, thereby taking into account the position changed by the user in step c) and the position changes of the remaining vertebrae computed in step d).

Description

technical field [0001] The present invention relates to a computer program for spinal mobility simulation. Such procedures may be used to configure spinal implants, such as cages or other fusion implants, or non-fusion implants such as intervertebral disc prostheses. The invention also relates to a spine simulation method. Background technique [0002] In the treatment of diseases, injuries or deformities affecting the moving parts of the spine, particularly the disc tissue, it has long been known to remove some or all of the degenerated, ruptured or otherwise failed discs. In cases involving intervertebral disc tissue removed or otherwise missing from the spinal column of motion, corrective measures are indicated to ensure proper spacing between the vertebrae previously separated by the removed disc tissue. [0003] Sometimes two adjacent vertebrae are fused together using bone grafts, artificial fusion components, or other devices. Artificial fusion components typically...
