A medical implant is provided that includes a bone plate having an aperture therethrough. The aperture receives a portion of the bone anchor. A retention mechanism is coupled to the bone plate. The retention mechanism includes a retainer and a biasing member. The biasing member is operatively engaged with at least the retainer. The insertion of the bone anchor in the aperture causes the retainer to move to a first position and elastically deform the biasing member. The biasing member causes the retainer to move to the second position to retain the bone anchor in the bone plate.
