Abstract
A method of tailoring a spinal implant to correspond to a specific patient's needs includes: pre-operatively evaluating a patient to determine a desired spinal segment response; and modifying one or more features of flexures of an implant to provide the desired spinal segment response. Modifying one or more features of flexures of the implant can include modifying one or more of a thickness, width, length and/or shape of the features of the flexures. Various systems for executing the methodologies taught herein are also provided.
Claims22
A method of tailoring a spinal implant to correspond to a specific patient's needs, the method comprising:
- pre-operatively evaluating information regarding a patient to determine a desired spinal segment stiffness response, comprising:
- determining a first range of motion for a target spinal segment, the first range of motion for the target spinal segment comprising at least two of:
- a flexion/extension component;
- a lateral bending component;
- an axial rotation component;
- and
- a compression component;
- wherein the determining the first range of motion for the target spinal segment comprises:
- manipulating the target spinal segment within the first range of motion under a load;
- and
- capturing and reviewing images of the target spinal segment as manipulated along the at least two of the flexion/extension component, the lateral bending component, the axial rotation component, and the compression component;
- determining a hysteresis curve for the target spinal segment based on the first range of motion as determined from the images;
- and
- modifying one or more flexures of the spinal implant to cause the spinal implant to correspond with the first range of motion of the target spinal segment to provide the desired spinal segment stiffness response.
