1. A proximal portion of an implant for repairing a multipart fracture of a proximal end of a humerus of a human, the proximal portion comprising:
an asymmetric body having a proximal end, a distal end opposite the proximal end, a medial side, a lateral side opposite the medial side, an anterior edge, a posterior edge opposite the anterior edge, and a medial surface extending along at least a portion of the medial side, the medial surface having a proximal end and a distal end;
wherein the distal end is configured to be coupled to a proximal end of an intramedullary nail, and
wherein the asymmetric body is sized and shaped to be implanted so as to be surrounded by bone within a proximal volume of a humerus of a human;
a humeral head support, wherein the humeral head support comprises:
a base portion joined to the asymmetric body, and
a support portion extending from the base portion,
wherein the support portion extends from the base portion in a direction such that the support portion is configured to extend from the base portion diagonally in a medial and distal direction when the base portion is attached to the proximal end of the implant, and
wherein the support portion is positioned with respect to the base portion so as to be positioned between the humeral head of the humerus and a lesser tuberosity of the humerus so as to support the humeral head of the humerus during a repair of a four-part fracture of the humerus; and
at least one anchoring point formed in the asymmetric body, the at least one anchoring point configured to engage an anchoring device to thereby anchor the proximal portion to a portion of the humerus.
