International ClassA61B 017/00AbstractPresented is a metallic cannulated rivet adapted for implantation in a bone mass through use of arthroscopic or open surgery for attachment of soft tissue thereto. The rivet in a first configuration is implanted, following which, a portion of the implanted rivet projecting from the bone site and penetrating the soft tissue is reformed in situ to clamp the soft tissue to the bone site. In a second aspect, the invention comprises the method and instrumentalities for effecting implantation of the rivet and reformation thereof in situ to mechanically clamp the soft tissue to the bone site. The method includes forming a small portal or incision to expose and prepare the bone site, torn or severed soft tissue is mobilized to intimately contact the bone site, the soft tissue is retained in proper position and a K-wire is advanced through the portal to penetrate the soft tissue and the bone mass to a predetermined depth and mark the point of implantation of the cannulated rivet. Thereafter, the rivet in its first configuration is advanced along the K-wire and inserted through the formed aperture in the soft tissue and anchored in the bone mass at the bone site with its proximate end projecting above the soft tissue. The head of the rivet is next reformed to clamp the soft tissue to the bone site, and the portal is closed.Field of SearchSuture retaining means (e.g., buttons)Orthopedic fastener Threaded fastener element Staple or similar driven fastener Internal fixation means Orthopedic instrumentation Femoral screw Anti-rotation or keeper means Femoral nail Expanding Expanding in diameter or length Surgical mesh, connector, clip, clamp or band Design of fastener or substructure restricts rotation (e.g., flattened head rotatable in receiving slot, depression in substructure, bolt clipped to substructure) Mass of bolt head or nut offset from fastener longitudinal axis Fastener having a deformable portion or deforms substructure (e.g., prong) Nut assembled to substructure by plastically deformable region on nut Region on inwardly facing surface of bolt head or nut Surface extends radially beyond flat sides of bolt head or nut And includes resilient flange Having axially directed projection or recess Plural, radially extending, and generally equally spaced INDEPENDENT, HEADED, APERTURE PASS-THROUGH FASTENER | |
