Abstract
The following relates to patient-specific or patient-matched, customized apparatus for use in surgical procedures, including various interbody procedures. The patient-matched apparatus may be a modular implant, a monolithic implant, and may include an instrument for use in procedures involving a modular or monolithic implant. One or more patient-matched apparatus described herein may be configured for use with a guide, with robotic instrumentation, or with augmented reality system.
Claims19
A modular, patient-matched implant assembly, comprising:
- an upper endplate;
- a lower endplate;
- a medial component selectively positionable between the upper endplate and the lower endplate and comprising at least a top surface and a bottom surface;
- the upper endplate comprising a first surface and a second surface, the first surface comprising one or more patient-specific contours determined from the anatomical data of a specific patient, the second surface complementary to the top surface of the medial component;
- the lower endplate comprising a first surface and a second surface, the first surface comprising one or more patient-specific contours determined from the anatomical data of a specific patient, the second surface complementary to the bottom surface of the medial component;
- wherein the upper endplate, lower endplate and medial component are secured together by one or more screws;
- and
- wherein the assembly comprises two sets of screws secured perpendicular to the medial component, a first set of the two sets of screws oriented in a first direction and a second set of the two sets of screws oriented in a second direction.
A method for fabricating a modular, patient-matched implant comprising the steps of:
- acquiring patient anatomical data, preferably in the form of images;
- segmenting and converting the data into a 3D model representative of the patient anatomical data;
- adjusting the 3D model based upon input from at least one individual;
- determining a maximum length, width, height and wedge angle(s) for the specific patient;
- determining a maximum footprint of a device that is able to conform to the patient anatomical data;
- determining the height and wedge angle of the device for manufacture specific to the patient;
- determining a first dimension of a medial component of the device;
- determining a second and third dimensions of an upper and lower endplates, including:
- (a) defining contours of an upper surface of the upper endplate to match a lower surface of the adjacent vertebral body;
- (b) defining contours of a lower surface of the upper endplate to match an upper surface of the medial component;
- (c) defining the contours of a lower surface of the lower endplate to match an upper surface of the adjacent vertebral body;
- and
- (d) defining the contours of an upper surface of the lower endplate to match a lower surface of the medial component;
- wherein the patient-matched implant further comprises a first set of two sets of screws oriented in a first direction and a second set of two sets of screws oriented in a second direction, the first and second set of screws inserted through the medial component, the upper endplate and the lower endplate.
