Light emitting bone implants

A bone implant implanted in a bone of a patient, the bone implant comprising:

• a rod having an aperture extending entirely through the rod, the aperture to receive a fastener to couple the rod to the bone of the patient;
• a light source disposed on the rod, the light source to emit light onto a portion of the bone of the patient, adjacent the rod to at least one of stimulate bone growth or reduce bone loss;
• a controller operatively coupled to the light source via a frangible lead;
• and
• wherein the controller is to control power supplied to the light source to enable the bone implant to deliver doses of light of four Joules to six Joules of energy per day.

A bone implant, the bone implant being implanted in a bone of a patient, the bone implant comprising:

• a light source to emit light having a wavelength from about 600 nanometers to about 950 nanometers, the light source implanted in the bone of the patient;
• an aperture extending through the bone implant, the aperture to receive a fastener to secure the bone implant to the bone;
• and
• wherein the light source delivers a predetermined dose of light to the bone of the patient.
