An extended deltoid tensioning humeral head which includes a humeral prosthetic and a deltoid tensioning device to replace a shoulder joint for a patient that may be suffering from shoulder arthritis or poor rotator cuff functionality. The humeral prosthetic consists of a humeral head and a humeral stem to replace the humerus of the patient. The deltoid tensioning device provides a means to tension the muscle fibers of the deltoid providing increased abduction motion of the arm. The extended deltoid tensioning humeral head provides an anatomical alternative for the replacement of a shoulder joint opposed to the reverse total shoulder arthroplasty.
