Patient-specific spinal fusion devices and associated systems and methods

A patient-specific spinal interbody implant, comprising:

• a cage body configured to be delivered into spine of a subject, the cage body is asymmetrical with respect to a mid-sagittal plane of the cage body and is asymmetrical with respect to a transverse plane of the cage body, wherein the cage body includes
• a first patient-specific endplate having a patient-contoured region,
• an interior region including a plurality of solid regions and a plurality of lattice regions, wherein each of the solid regions is located between a respective pair of the lattice regions, and
• an outer solid rim defining a continuous surface extending along a periphery of the interior region, wherein the outer solid rim includes a concave section and a convex section, wherein the patient-contoured region protrudes outwardly past the concave section, and
• an anchor-receiving throughhole extending through the cage body and the patient-contoured region;
• and
• an anchor configured to be positioned within the anchor-receiving throughhole and to extend through the first patient-specific endplate and a first vertebral endplate of the spine of the subject such that the patient-contoured region is positioned along the first vertebral endplate when the cage body is positioned between the first vertebral endplate and a second vertebral endplate of the spine.

A patient-specific spinal interbody implant comprising:

• a cage body including
• a first patient-specific endplate having a first patient-contoured region configured to contact a first endplate of a spine of a patient,
• a second patient-specific endplate having a second patient-contoured region configured to contact a second endplate of the spine,
• a first lattice region positioned between the first patient-specific endplate and the second patient-specific endplate,
• a second lattice region positioned between the first patient-specific endplate and the second patient-specific endplate,
• a continuous tubular portion defining an anchor-receiving throughhole extending through the cage body, and
• a strut extending between the first patient-specific endplate and the second patient-specific endplate, wherein the strut is positioned between the first lattice region and the second lattice region, and wherein the second lattice region is positioned between the strut and an entrance opening of the anchor-receiving throughhole.

A patient-specific spinal interbody implant comprising:

• a cage configured to be implanted along a spine of a patient, the cage including
• a first endplate having a first patient-contoured region,
• a second endplate having a second patient-contoured region,
• an interior region between the first endplate and the second endplate and including plurality of solid regions and a plurality of lattice regions, wherein each of the plurality of solid regions is located between a respective pair of the plurality of lattice regions, and
• an anchor-receiving throughhole extending through the cage and the first patient-contoured region;
• and
• an anchor configured to be positioned within the anchor-receiving throughhole and to extend through the first endplate of the cage and a first anatomical endplate of the spine such that the first patient-contoured region is positioned along the first anatomical endplate.

An interbody implant comprising:
