Abstract
Official abstract text for this publication.
A reconfigurable bone adjustment device includes a first member configured for attachment to a first bone fragment, portion, etc., a second member configured for attachment to a second bone fragment, portion, etc., a drive mechanism configured to move the second member relative to the first member, a threaded rod having a proximal end operatively coupled to the drive mechanism and a distal end operatively coupled to the second member so that rotation of the drive mechanism rotates the threaded rod and moves the second member relative to the first member, and a dynamic segment positioned between the first and second members to enable compression of the second member relative to the first member to stimulate bone growth. The dynamic segment may be a silicone/rubber compressible member or assembly, a metallic spring, a non-metallic shock absorbing material or washer, or the like.
First claim
Opening claim text (preview).
The invention claimed is: 1. A reconfigurable bone adjustment device comprising: a first member configured for attachment to a first bone fragment; a second member configured for attachment to a second bone fragment; a drive mechanism configured to move the second member relative to the first member; a threaded rod having a proximal end operatively coupled to the drive mechanism, and a distal end operatively coupled to the second member so that operation of the drive mechanism rotates the threaded rod and moves the second member relative to the first member; and a dynamic segment positioned between the first and second members to enable compression of the second member relative to the first member to stimulate bone growth; wherein the dynamic segment includes a compressible assembly including a compressible member sandwiched between first and second end plates, the compressible member being selected from one of a silicone and a rubber, and the first and second end plates being manufactured from a metallic material. 2. The reconfigurable bone adjustment device of claim 1 , wherein the dynamic segment is positioned within the first member. 3. The reconfigurable bone adjustment device of claim 1 , wherein the dynamic segment is positioned adjacent to the drive mechanism. 4. The reconfigurable bone adjustment device of claim 1 , wherein the compressible member is molded to the end plates. 5. The reconfigurable bone adjustment device of claim 1 , wherein the compressible assembly including the compressible member and the first and second end plates include an opening formed therein for enabling the threaded rod to pass therethrough. 6. A reconfigurable bone adjustment device comprising: a first member configured for attachment to a first bone fragment; a second member configured for attachment to a second bone fragment; a drive mechanism configured to move the second member relative to the first member; a threaded rod having a proximal end operatively coupled to the drive mechanism, and a distal end operatively coupled to the second member so that operation of the drive mechanism rotates the threaded rod and moves the second member relative to the first member; and a dynamic segment positioned between the first and second members to enable compression of the second member relative to the first member to stimulate bone growth; wherein the dynamic segment includes a containment cup and a compressible member, the containment cup includes a ledge projecting along an outer circumference thereof, the ledge defining a pocket arranged and configured to receive at least a portion of the compressible member therein. 7. The reconfigurable bone adjustment device of claim 6 , wherein the containment cup is manufactured from a metallic material, the compressible member is manufactured from one of a silicone or a rubber. 8. The reconfigurable bone adjustment device of claim 6 , wherein the compressible member extends beyond the ledge of the containment cup. 9. The reconfigurable bone adjustment device of claim 6 , wherein the dynamic segment is positioned within the first member. 10. The reconfigurable bone adjustment device of claim 6 , wherein the dynamic segment is positioned adjacent to the drive mechanism.
