An artificial bone replacement device includes opposite end connectors interconnected to each other by a flexible unit consisting of an outer plastic tube and an inner plastic tube. The flexible telescoped tubes provide a flexible joint permitting angular movement of the connectors relative to each other. The connector are constructed for connection to a bone structure of a cadaver or to a bone replacement element in a cadaver such as a tubular member. A shoulder replacement device includes a first connector having a projecting screw member for threading into the collar bone. The opposite connector includes a tubular member connected to the tubular plastic tubes and having an opposite outer end tubular connector for interconnection to a bone or an artificial replacement member. The tubes are secured to the connectors by a cross screw threaded through the respective connectors and tubes. A similar screw is provided to connect the outer tubular connector to the bone or a bone replacement element. The replacement device can be constructed with the screw members at the opposite end or with both end connectors formed as tubular members for telescopic reception of bone structure or bone replacement elements.
An artificial bone replacement device for replacement of a removed bone joint structure of a cadaver, said joint structure having a first existing bone member and a second existing bone member, comprising a first connector unit for connection to the first existing bone member of the removed joint structure of the cadaver, a second connector unit for connection to the second existing bone member of said cadaver for the same removed joint structure, an elongated flexible unit connected to said first and second connection units, said elongated flexible unit being bendable about an intermediate location between said connector units into a plurality of different planes for essentially unrestricted preset orientation of said connected first and second existing bone members in a single plane and in any one of said plurality of different planes relative to each other and holding said existing bone members in said preset orientation.
A shoulder replacement device for replacing the shoulder structure of a cadaver, said shoulder structure having a collar bone and an arm member, comprising a first connector unit having an attachment element for embeddment in the collar bone of a cadaver, a second connector unit for connection to the arm member of the cadaver, and an elongated semi-flexible unit connected between said first and second connector unit, said semi-flexible unit being bendable in a plurality of planes for angularly offsetting said connector units in the same plane or into different planes relative to each other and thereby orient said arm member relative to said collar bone.
An elbow replacement device for replacing an elbow structure of a cadaver, comprising a first connector unit for attachment to an upper arm bone of a cadaver, a second connector unit for attachment to a lower bone of a cadaver, an elongated semi-flexible unit connected between said first and second connector unit, said semi-flexible unit being bendable in a plurality of planes for angularly offsetting said connector units in the same plane or in different planes relative to each other and orient said upper and lower bones relative to each other.
