Minimally invasive shoulder implant and method

A method of implanting a prosthetic stemless shoulder implant comprising:

• making an incision into a shoulder area of a patient;
• inserting a first cutting instrument through the incision and through a rotator cuff interval of the patient;
• resecting a central portion of a native humeral head of the patient with the first cutting instrument;
• removing the central portion of the native humeral head of the patient so that a central void remains where the central portion of the native humeral head was previously positioned;
• inserting a second cutting instrument through the incision, through the rotator cuff interval, and into the central void;
• resecting a medial portion of the native humeral head adjacent the central void;
• removing the medial portion of the native humeral head from the patient;
• resecting a lateral portion of the native humeral head adjacent the central void;
• removing the lateral portion of the native humeral head from the patient;
• implanting a base of a prosthetic stemless shoulder into a proximal portion of the humerus after passing the base through the rotator cuff interval;
• coupling a first portion of a prosthetic humeral head to the base after passing the first portion of the prosthetic humeral head through the rotator cuff interval;
• and
• coupling a second portion of the prosthetic humeral head to the base and to the first portion of the prosthetic humeral head after passing the second portion of the prosthetic humeral head through the rotator cuff interval,
• wherein resecting the medial portion of the native humeral head and resecting the lateral portion of the humeral head occurs after the central portion of the native humeral head is resected and removed from the patient.
