1. A surgical instrumentation system for a shoulder arthroplasty comprising:
a retractor including:
a curved section structured to wrap around and substantially engage a posterior portion of a humeral head,
a shaft extending from the curved section, said shaft defines a first plane,
an alignment guide extending from the retractor, the alignment guide comprising a plurality of primary alignment shafts, each of the primary alignment shafts extends obliquely from a central location of the shaft, and
an orthogonal segment defining a second plane orthogonal to the first plane and connecting the shaft to a distal end of the alignment guide; and
a resection guide attachable to the shaft of the retractor and configured for lockable adjustment along the shaft, the resection guide including a guide surface for guiding a cutting tool to resect the humeral head;
wherein a first of the primary alignment shafts extends at a first angle of about 140 to about 145 degrees, a second of the primary alignment shafts extends at a second angle of about 152 to about 157 degrees, and a third of the primary alignment shafts extends at a third angle of about 165 to about 169 degrees, each with respect to the first plane, and
wherein the curved section, the alignment guide, the plurality of primary alignment shafts and the orthogonal segment are of unitary construct.
