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.
