Abstract
Bone plates for engaging bone members are described herein. The bone plates can receive one or more screws to secure the bone plates to an underlying bone member. The one or more screws can be inserted into bone plate holes that can be considered locking or non-locking. The bone plates described herein can have particular combinations of locking and/or non-locking holes. In addition, instruments such as distal and proximal aiming guides can accompany the bone plates to guide one or more screws into the bone plates.
Claims18
A system for treating a fracture in a bone, comprising:
- an aiming arm having a proximal end, a distal end, a first side, and a second side, the aiming arm comprising a plurality of openings, wherein each of the plurality of openings is spaced at predetermined intervals between the proximal end and the distal end, a bone plate configured to engage the bone, the bone plate comprising a proximal end, a distal end, a head portion, a neck portion and a shaft portion, wherein the head portion comprises a first row of openings and a second row of openings for receiving one or more fasteners therein, wherein the shaft portion comprises at least one additional opening for receiving a fastener therein;
- an attachment guide operatively connected to the first side of the proximal end of the aiming arm, the attachment guide including at least one opening that is coaxial with an opening in the neck portion of the bone plate;
- an attachment post having a first and a second end, wherein the attachment post is operable to pass through the at least one opening in the attachment guide and the opening in the neck portion of the bone plate;
- wherein the first end of the attachment post is operatively connectable to the opening in the attachment guide and the second end is operatively connectable to the opening in the neck portion of the bone plate;
- and a proximal targeting guide comprising openings that are coaxial with the first row of openings and the second row of openings in the head portion of the bone plate.
An apparatus A system for treating a fracture in a bone, comprising:
- a bone plate configured to engage the bone, the bone plate comprising a proximal end, a distal end, a head portion, a neck portion and a shaft portion, wherein the shaft portion comprises holes operable to receive fasteners therein;
- an aiming arm having a substantially rectangular shaft having a proximal end and a distal end, the substantially rectangular shaft including holes that are coaxial with the holes in the shaft portion of the bone plate;
- an attachment guide extending away from a first side of the proximal end of the shaft of the aiming arm, the attachment guide configured and dimensioned so that a hole in the attachment guide is coaxial with a hole in the neck portion of the bone plate;
- a fastener that is operatively connected to the hole in the neck portion of the bone plate;
- and an attachment post that is operatively connected to the fastener, the neck portion of the bone plate, and the hole in the attachment guide to form a rigid connection between the aiming arm and the bone plate;
- and a proximal targeting guide operatively connected to the head portion of the bone plate, wherein the proximal targeting guide includes at least one hole that is coaxial with a hole in the head portion of the bone plate.
