ABSTRACT:
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.
