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.

Claims (39)

1 . 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.

2 . The modular, patient-matched implant assembly of claim 1 , wherein the patient-matched implant assembly is configured for a TLIF trajectory, an ALIF trajectory, a DLIF trajectory, a PLIF trajectory, a TLIFO trajectory, an OLIF trajectory, a XLIF trajectory, or a cervical interbody trajectory.

3 . The modular, patient-matched implant assembly of claim 2 , wherein the leading edge of the implant assembly comprises a tapered shape to facilitate insertion along a chosen trajectory.

4 . The modular, patient-matched assembly of claim 1 , wherein the first direction is an opposing direction to the second direction.

5 . The modular, patient-matched implant assembly of claim 1 , wherein the medial component is provided in a variety of lengths, widths, heights and angles.

6 . The modular, patient-specific implant assembly of claim 5 , wherein the lengths, widths, heights and angles of the medial component are standardized.

7 . The modular, patient-matched implant assembly of claim 1 , wherein at least one of the upper endplate, lower endplate and medial component comprise a plurality of apertures.

8 . The modular, patient-matched implant assembly of claim 7 , wherein one or more of the plurality of apertures comprise a porous structure.

9 . The modular, patient-matched implant assembly of claim 8 , wherein the porous structure is patient-specific and determined from the anatomical data of the specific patient.

10 . The modular, patient-matched implant assembly of claim 1 further comprising a central aperture that spans the upper endplate, lower endplate and medial component.

11 . The modular, patient-matched implant assembly of claim 1 , wherein the one or more patient-specific contours of the upper and lower endplates are additively manufactured.

12 . The modular, patient-matched implant assembly of claim 1 , wherein the at least a top surface and a bottom surface of the medial component comprise a slot for mating with adjoining surfaces of the upper and lower endplates.

13 . The modular, patient-matched implant assembly of claim 1 , further comprising a tool having a threaded portion, the threaded portion configured to engage the one or more screws for securing the upper and lower endplates to the medial component.

14 . The modular, patient-matched implant assembly of claim 1 further comprising at least one pin.

15 . The modular, patient-matched implant assembly of claim 14 , wherein the at least one pin is secured to the medial component by a friction fit.

16 . The modular, patient-matched implant assembly of claim 1 , wherein the at least one pin further comprises a friction fit with the upper endplate.

17 . The modular, patient-matched implant assembly of claim 1 , wherein the at least one pin further comprises a friction fit with the lower endplate.

18 . The modular, patient-matched implant assembly of claim 1 , wherein the implant assembly is assembled in situ.

19 . 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.
