In certain embodiments, the medial bone plate 400 is connectable to other implants such as an intramedullary nail, lateral bone plate, other medial bone plate, arthroplasty implant, or the like. The medial bone plate 400 may connect to these other implants using fasteners or may connect by way of connectors that may be formed in one or the other or both of the medial bone plate 400 and the other implant. |

Figure 4A is a perspective view of a medial bone plate 400 deployed on a long bone, such as a femur 102, according to one embodiment. The medial bone plate 400 includes a proximal end 402, a distal end 404, and a body 406. The proximal end 402 includes one or more arms 408. In certain embodiments, an arm 408 may be referred to as a tab, finger, or the like. In the illustrated embodiment, one arm 408 extends from the body 406 in an anterior direction relative to the femur 102. In another embodiment, the one or more arms 408 may extend from the body 406 in a posterior direction relative to the femur 102. |

The medial bone plate 400 may be manufactured to have a variety of different widths and/or thicknesses in order to provide a medial bone plate 400 with a desired level of rigidity/stiffness and/or flexibility or both. Accordingly, the components of the medial bone plate 400 may be sized to provide a desired length, width, height, or thickness and the material used for one or more components may be selected to provide a desired level of rigidity and/or flexibility, or both. |

In one embodiment, the medial bone plate 400 is configured, designed, and/or engineered to account for the close proximity of the large femoral artery of a patient that runs along the medial side of the femur 102. In particular, the femoral artery sits very close to the shaft 410 of the femur 102 and is not as close to the femur 102 near the distal end 412 of the femur 102. The medial bone plate 400 is configured for percutaneous deployment through an entry point/incision on the inside of the thigh (i.e., medial side at the distal end). |

The arm 408 at, or near, the proximal end 402 provides for fixation of medial bone plate 400 to the femur 102. The arm 408 can include one or more fastener openings 414 positioned at a variety of positions along the arm 408. The one or more fastener openings 414 are each configured to receive a fastener of a variety of types and configurations. Fasteners placed in the fastener openings 414 may engage the cortex of the long bone at a variety of angles, such as between 20 degree and 90 degrees in relation to a longitudinal axis of the long bone. Similarly, the positioning of the fastener openings 414 on the arm 408 can provide for a variety of different angles for the deployment of fasteners into the bone in relation to the medial bone plate 400. In one embodiment, the fasteners may be deployed at an angle between about 20 degrees relative to a longitudinal axis of the long bone to 90 degrees to 180 degrees (perpendicular to the body 406 of the medial bone plate 400). |

In certain embodiments, the presented solution includes the use of a protected drill sleeve/drill guide protector for deployment of fasteners into the fastener openings 414 of the arm 408 from the lateral side of the long bone. As one example, a surgeon may use a protected drill sleeve/drill guide protector similar to those used for fixation of an anterior cruciate ligament (ACL) guide. Use of the protected drill sleeve/drill guide protector when deploying from the lateral side of the long bone can protect soft tissue of the patient at the entry point and mitigate medial over penetration when the fasteners are deployed. |

The distal end 404 may include a fixation feature 416 that includes one or more fastener openings 414. The fixation feature 416 may be shaped and contoured to contact and follow a contour of a medial condyle of the long bone. The body 406 may be configured to contact a medial surface of a long bone, such as femur 102. Accordingly, the body 406 may include a curve or bow shape to follow a contour of the medial surface of the femur 102. |

In one embodiment, the fastener openings 414 ( in the body 406, the arm 408, and/or fixation feature 416) and/or fixation feature 416 may be configured to use fasteners such as screws, pins, bones screws, or the like. In other embodiments, the medial bone plate 400 may include other fixation features and the corresponding components for those fixation features in place of the fastener openings 414 and/or fixation feature 416. For example, the fastener openings 414 and/or fixation feature 416 may instead comprise anchors, nuts, threaded openings, buttons, stops, of the like for implementing one or more of a variety of fixation technologies. For example, fixation of the medial bone plate 400 to the long bone may be done using cables, wires, sutures, suture buttons, flexible fasteners or the like. |
