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 , and a posterior edge opposite the anterior edge ; - a medial surface extending along at least a portion of the medial side , the medial surface having a proximal end and a distal end ; - a protrusion forming the lateral side of the asymmetric body, the protrusion being offset in an anterior direction, the protrusion extending in a direction so as to point toward a bicipital groove of the humerus when the proximal portion is implanted in the humerus, - an anterior support surface defined by an anterior side of the protrusion and extending to the anterior edge of the asymmetric body, the anterior support surface being configured to support a lesser tuberosity of the proximal end of the humerus; - a posterior support surface defined by a posterior side of the protrusion and extending to the posterior edge of the asymmetric body, the posterior support surface being configured to support a greater tuberosity of the proximal end of the humerus; - a generally triangular angled surface having a first side defined by the proximal end of the medial surface , a second side defined by a proximal end of the anterior support surface , and a third side defined by a proximal end of the posterior support surface , wherein the generally triangular surface is angled with regard to the medial surface ; 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. - 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 , and a posterior edge opposite the anterior edge ; - a medial surface extending along at least a portion of the medial side , the medial surface having a proximal end and a distal end ; - a protrusion forming the lateral side of the asymmetric body, the protrusion being offset in an anterior direction, the protrusion extending in a direction so as to point toward a bicipital groove of the humerus when the proximal portion is implanted in the humerus, - an anterior support surface defined by an anterior side of the protrusion and extending to the anterior edge of the asymmetric body, the anterior support surface being configured to support a lesser tuberosity of the proximal end of the humerus; - a posterior support surface defined by a posterior side of the protrusion and extending to the posterior edge of the asymmetric body, the posterior support surface being configured to support a greater tuberosity of the proximal end of the humerus; - a generally triangular angled surface having a first side defined by the proximal end of the medial surface , a second side defined by a proximal end of the anterior support surface , and a third side defined by a proximal end of the posterior support surface , wherein the generally triangular surface is angled with regard to the medial surface ; 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. <EOS>
