Bone stabilization systems
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. The bone plates can include features that accommodate the underlying anatomy of different types of bone, such as the condylar region of a femur.
