An orthopedic implant structure is provided for joining and retaining components of a multi-part orthopedic device. The orthopedic implant joining and retaining structure may be embodied in two or more components of the multi-part orthopedic device. In one form, the multi-part orthopedic implant structure is a resilient snap structure such as a resilient flange in one part and a channel structure formed in another part of an orthopedic implant. A channel of the channel structure may have a cavity formed at a rear of the channel that accepts a configured lip formed on an end of the resilient flange. According to another embodiment, the retaining structure includes resilient snap flanges formed on an interconnection component of the multi-part orthopedic implant. A corresponding bore in another part of the multi-part orthopedic implant receives the interconnection component.
