  • Patent number: 8657820
    Abstract: Systems and methods for stabilizing portions of bone are provided. In some aspects, a bone plate system includes a plate configured to be fastened to at least one bone portion. The plate includes a keel slot and a locking assembly. The bone plate system also includes a keel configured to extend into the at least one bone portion through the keel slot. The locking assembly is configured to substantially prevent the keel from dislodging from the plate when the keel extends into the at least one bone portion through the keel slot.

  • Publication number: 20130267955
    Abstract: Systems and methods for stabilizing portions of bone are provided. In some aspects, a bone fixation system can include a plate configured to be fastened to a growing bone to control growth of the bone in at least one direction. The system can include a keel structure having a longitudinal axis. The keel can extend from the plate into the bone to permit bone growth along the keel longitudinal axis on one side of the bone while the plate generally inhibits growth on the other side of the bone.

  • Publication number: 20110087229
    Abstract: Systems and methods for stabilizing and/or compressing portions of bone are provided. In some aspects, a bone plate system may comprise a plate having a bone engaging surface. The plate may be fastened to two bone portions having a joint line therebetween. The system may also include a keel projecting from the bone engaging surface. The keel may extend into the bone portions and span the joint line when the plate is fastened to the bone portions. In some aspects, a ratio of an average thickness of the plate to an average width of the plate may be less than or equal to about 0.11.

  • Publication number: 20100179591
    Abstract: A method according to embodiments of the present invention for repairing an Achilles tendon that has completely or partially ruptured leaving a distal stump extending from a calcaneus and a proximal stump, the proximal stump having a proximal stump end, and the distal stump having a distal stump end, includes attaching a first suture to the distal stump, positioning an augmentation patch against an anterior portion of the Achilles tendon, attaching a second suture to the proximal stump and to the augmentation patch, apposing the proximal stump end and the distal stump end such that a gap between the proximal stump end and distal stump end is minimized or eliminated, joining the first suture with the second suture to secure the proximal stump to the distal stump, and attaching the augmentation patch to the calcaneus.

  • Patent number: 7625409
    Abstract: A fixed-bearing ankle prosthesis may include tibial and talar components whose articulating surfaces directly contact one another. The tibial component defines medial and lateral concave condylar facets separated by a convex central portion. The talar component includes medial and lateral convex condyles separated by a concave central portion. The condyles each have a single radius of curvature in a medial-lateral plane such that each condyle has a circular-arc cross-section continuously extending from the respective medial or lateral edge of the talar component to the concave central portion. The medial-lateral radii of the condyles are smaller than corresponding radii of the condylar facets.
