Orthopedic implant with improved variable angle locking mechanism

An orthopedic implant comprising:

• an outer surface;
• a bone contacting surface opposite the outer surface;
• and
• at least one opening extending between the outer surface and the bone contacting surface, the at least one opening including first and second rows of fins, each of the first and second rows of fins including a plurality of fins circumferentially disposed about the at least one opening, the fins in the first row of fins being aligned in a vertically stacked relationship with the fins in the second row of fins;
• wherein, for each vertically stacked relationship, the fin in the first row of fins has one of a first configuration and a second configuration, the fin in the second row of fins has the other one of the first configuration and the second configuration, the first configuration being different than the second configuration;
• and
• wherein the first and second configurations are selected from one of a different length as measured from a base of the fin to a tip of the fin, and a different cross-sectional area at the tip of the fin.
