Intervertebral cage with integrated transmitter

A spinal implant configured to securely mate with anatomical elements in a patient, the spinal implant comprising:

• an intervertebral cage body having
• a patient-specific textured upper surface configured to engage a first vertebral endplate of the patient, and
• a patient-specific textured lower surface configured to engage a second vertebral endplate of the patient, wherein the patient-specific textured upper surface is angled with respect to the patient-specific textured lower surface for lordotic correction;
• a proximity communication component inside the intervertebral cage;
• and
• a memory operatively coupled to the proximity communication component, the memory storing data after the spinal implant is implanted in the patient, wherein the data includes
• texturing data associated with manufacturing of the patient-specific textured upper surface and the patient-specific textured lower surface, and
• a private key, wherein the memory is configured to provide the private key through the proximity communication component to an external device for enabling the external device to access one or more electronic medical records associated with the patient in which the spinal implant is implanted, from a distributed blockchain ledger of electronic medical records.
