Claim Text:
1. A surgical method comprising: providing a fastener having a head member and a shaft member; providing a crown, wherein the crown comprises an upper surface, a bottom surface and an opening formed between the upper and bottom surfaces, wherein the crown further comprises a slit formed in the crown, wherein the slit extends from the upper surface to the bottom surface, wherein the slit extends from an outer most surface of the crown to the opening in the crown; and inserting the fastener through the opening of the crown and into a bone member, wherein the head member of the fastener applies a pressure to the surface of the crown to cause deformation of the crown, thereby causing free ends of the crown to move toward a common plane, wherein the first free end or the second free end comprise one or more protrusions configured and dimensioned to interfere with a portion of the opposing free end to provide tactile or audible feedback to a user, wherein as the fastener is inserted into bone, the deformation of the crown allows for increasing load distribution by the crown on the surface of the bone.
