Abstract
A device for promoting the healing of bones has a pair of elongated carriers which support screws to be anchored in bone structure. The screws are movable longitudinally of the carriers by means of spindles. The carriers are joined to one another by a connector consisting of a rigid rod having a ball at either end. The balls are received in part-spherical sockets formed in the respective carriers and can be fixed relative to the carriers via screws.
Claims17
A device for promoting the healing of bones, comprising first and second supports having confronting end portions;
- at least one anchoring member separably mounted on each of said supports and designed to be anchored in bone structure;
- a substantially barbell-shaped connector for joining the confronting end portions of said supports to one another, said connector including first and second at least approximately spherical elements each mountable on the end portion of the respective support, and a spacer rigidly connecting said elements to one another, said device being free of protrusions extending between said supports and the interiors of the respective elements, the end portion of each of said supports being provided with a first socket having the configuration of a quarter of a sphere;
- and means for arresting said connector relative to said supports, including first and second confining members distinct from and arranged to cooperate with the respective supports and including second part spherical sockets complementary to the respective first sockets, each of said elements being receivable in the respective first and the respective second socket to establish a universal joint between said spacer and the respective support.
