DETAILED DESCRIPTION
[0284] Exemplary embodiments of the present disclosure will be best understood by reference to the drawings, wherein like parts are designated by like numerals throughout. It will be readily understood that the components of the present disclosure, as generally described and illustrated in the drawings, could be arranged, and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments of the devices, systems, and methods, as represented in the drawings, is not intended to limit the scope of the present disclosure but is merely representative of exemplary embodiments of the present disclosure.
[0285] The word exemplary is used herein to mean serving as an example, instance, or illustration. Any embodiment described herein as exemplary is not necessarily to be construed as preferred or advantageous over other embodiments. While the various aspects of the embodiments are presented in the drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
[0286] Standard medical planes of reference and descriptive terminology are employed in this specification. While these terms are commonly used to refer to the human body, certain terms are applicable to physical objects in general.
[0287] A standard system of three mutually perpendicular reference planes is employed. A sagittal plane divides a body into right and left portions. A coronal plane divides a body into anterior and posterior portions. A transverse plane divides a body into superior and inferior portions. A mid-sagittal, mid-coronal, or mid-transverse plane divides a body into equal portions, which may be bilaterally symmetric. The intersection of the sagittal and coronal planes defines a superior-inferior or cephalad-caudal axis. The intersection of the sagittal and transverse planes defines an anterior-posterior axis. The intersection of the coronal and transverse planes defines a medial-lateral axis. The superior-inferior or cephalad-caudal axis, the anterior-posterior axis, and the medial-lateral axis are mutually perpendicular.
[0288] Anterior means toward the front of a body. Posterior means toward the back of a body. Superior or cephalad means toward the head. Inferior or caudal means toward the feet or tail. Medial means toward the midline of a body, particularly toward a plane of bilateral symmetry of the body. Lateral means away from the midline of a body or away from a plane of bilateral symmetry of the body. Axial means toward a central axis of a body. Abaxial means away from a central axis of a body. Ipsilateral means on the same side of the body. Contralateral means on the opposite side of the body. Proximal means toward the trunk of the body. Proximal may also mean toward a user or operator. Distal means away from the trunk. Distal may also mean away from a user or operator. Dorsal means toward the top of the foot. Plantar means toward the sole of the foot. Varus means deviation of the distal part of the leg below the knee inward, resulting in a bowlegged appearance. Valgus means deviation of the distal part of the leg below the knee outward, resulting in a knock-kneed appearance.
[0289] The present disclosure relates to fracture plating devices, systems, and methods. Those skilled in the art will recognize that the following description is merely illustrative of the principles of the technology, which may be applied in various ways to provide many alternative embodiments. The present disclosure illustrates devices for plating systems for one or more fractures of a rib for the purposes of illustrating the concepts of the present design. However, it will be understood that other variations and uses are contemplated including, but not limited to, fractures of metatarsals, fractures of phalanges, metacarpals, and carpals, fractures of a fibula, fractures of an ulna, and other bone fractures.

[0470]
[0471] The shank portion 1457 may be smaller than a width of the first slot 105 and/or the second slot 115 to allow the ratchet fastener 1450 to translate along the length of the first slot 105 and/or the second slot 115. The tip portion 1462 may be configured to ease insertion of the ratchet fastener 1450 into a hole in a bone portion. The cannulation 1465 may be configured to slidably receive a tether 60. The ratchet portion 1460 may be configured to receive a ratchet cap 1470. The rounded edge 1468 may reduce stress on the tether 60 when the tether 60 exerts a force on the ratchet fastener 1450.
[0472] The ratchet portion 1460 may include a plurality of grooves. Each of the plurality of grooves may have a leading angle 1458 and a trailing angle 1459. The leading angle 1458 may be within a range of 15 to 45. More specifically, the leading angle 1458 may be within a range of 20 to 40. More specifically, the leading angle 1458 may be 30. The trailing angle 1459 may be generally perpendicular to a long axis of the shank portion 1457.
[0473] The ratchet fastener 1450 may be configured within a range of lengths from 5 mm to 30 mm and within a range of diameters from 3 mm to 8 mm. The ratchet fastener 1450 may be one of a set of differently-sized implants, each having a different length and/or diameter. The ratchet cap 1470 may be one of a set of differently-sized implants, each having a different diameter configured to engage each of the differently sized ratchet fasteners 1450.
[0474] The ratchet fastener 1450 may be configured to receive the ratchet cap 1470 so that the ratchet portion 1460 of the ratchet fastener 1450 engages the ratchet portion 1472 of the ratchet cap 1470. More specifically, the leading angle 1481 of the ratchet cap 1470 and the leading angle 1458 of the ratchet fastener 1450 may be configured to allow the ratchet cap 1470 to advance along a length of the ratchet fastener 1450 from the tip portion 1462 towards the head portion 1455.
[0475] Moreover, the trailing angle 1482 of the ratchet cap 1470 and the trailing angle of the ratchet fastener 1450 may be configured to prevent translation of the ratchet cap 1470 along a length of the ratchet fastener 1450 from the head portion 1455 towards the tip portion 1462.
[0476] The ratchet cap 1470 may create compression at the interface similar to the locking nut 1370, but the advantage may be that it the ratchet cap 1470 may not require a drive feature to install the ratchet cap 1470 and secure the construct. The drive feature on the previous concepts may require the cap to have some thickness to engage with. The ratchet cap 1470 may not require a non-circular drive feature to apply torque. Thus, the ratchet cap 1470 may be much thinner than the locking nut 1370. A thinner cap may result in a lower profile construct on the bone and thus may reduce irritation of the surrounding soft tissues.

[0483] In the undeformed configuration 1520 the bridge portion 1550 may include a bridge apex 1580. The bridge apex 1580 may be centrally located along the bridge portion 1550. In the undeformed configuration 1520 the fracture repair system 1500 may include a first leg spacing 1590. In the expanded configuration 1540 the fracture repair system 1500 may include a second leg spacing 1592. The first leg spacing 1590 may be less than the second leg spacing 1592.
[0484] The fracture repair system 1500 may be configured so that an external force is required to transition from the undeformed configuration 1520 to the expanded configuration 1540. Additionally, when the external force is removed, the fracture repair system 1500 will return from the expanded configuration 1540 to the undeformed configuration 1520 with no other externally applied forces.
[0485] An instrument/tool (not shown) may be used to elastically deform the fracture repair system 1500 from the undeformed configuration 1520 to the expanded configuration 1540. Once inserted into the tissue (bone and/or cartilage) the force of the instrument may be removed and the fracture repair system 1500 may return to the undeformed configuration 1520. The fracture repair system 1500 may be inserted to bridge a rib fracture in the expanded configuration 1540, and then may be used to compress the fractured bones back together as it moves back towards the undeformed configuration 1520.

[0537] Step 11 may include placing a first washer over the first tether end 62 and then over the tip portion of the first fastener and placing a second washer over the second tether end 64 and then over the tip portion of the second fastener.
[0538]
[0539] Step 12 may include placing a first locking nut 30 over the first tether end 62 and threading and tightening the first locking nut onto the threaded portion of the first fastener. Placing a second locking nut 30 over the second tether end 64 and threading and tightening the second locking nut onto the threaded portion of the second fastener.
[0540]
[0541] Step 13 may include removing the single tether 60 by pulling it with an endoscopic grasper, or similar instrument, through the VATS portal.
[0542] A method for stabilizing one or more fractures of a bone may include using a tether to advance a first fastener and/or a second fastener to the interior surface of the bone. The method may further include introducing the first fastener and/or the second fastener through a VATS portal. The method may also include introducing the plate to an exterior surface of the bone. The method may include advancing the fasteners through a hole in the bone so that a head portion contacts the interior surface and a distal end extends from the exterior surface of the bone. The method may further include receiving the distal end within a slot of the plate, and, using the fastener, securing the plate to the exterior surface of the bone.
[0543] A method for stabilizing one or more fractures of a portion of bone may include the following steps: [0544] Step 1 may include identifying one or more fractures of a bone. [0545] Step 2 may include drilling a first hole 15 and a second hole 16 wherein the first hole 15 and the second hole 16 are separated by a first fracture 21. The step may further include drilling additional holes through the bone on opposite sides of additional fractures, so that each fracture is between two holes in the bone. [0546] Step 3 may include inserting a first end 72 of a first flexible guide tube 70 through the first hole 15. Inserting a first end 72 of a second flexible guide tube 70 through the second hole 16. Pulling the first end 72 of the first flexible guide tube 70 and the first end of the second flexible guide tube out 70 through a VATS portal using an endoscopic grasper or similar instrument. Ensuring that a second end 74 of the first flexible guide tube 70 does not pass through the first hole 15 and ensuring that a second end 74 of the second flexible guide tube 70 does not pass through the second hole 16. The flexible guide tube 70 may be fabricated of silicone rubber or other biocompatible elastomeric material. [0547] Step 4 may include measuring the rib thickness and other features of patient anatomy and a location of the fracture. Selecting two or more fasteners from a range of available sizes based on patient anatomy and a location of the fracture. Selecting a plate from a range of available sizes based on patient anatomy and location/quantity of one or more fractures. [0548] Step 5 may include inserting a first tether end 62 through a first fastener and a second tether end 64 through a second fastener. [0549] Step 6 may include inserting a first tether end 62 into a second end 74 of the first flexible guide tube 70 and inserting the second tether end 64 into a second end 74 of the second flexible guide tube 70. [0550] Step 7 may include feeding the first tether end 62 and the second tether end 64 through the first flexible guide tube 70 and the second flexible guide tube 70, respectively until the first tether end 62 and the second tether end 64 protrude through the first end 72 of the first flexible guide tube 70 and the first end 72 of the second flexible guide tube 70. [0551] Step 8 may include removing the first flexible guide tube 70 and the second flexible guide tube 70 from the surgical site by pulling the first end 72 of the first flexible guide tube 70 and the first end 72 of the second flexible guide tube 70. [0552] Step 9 may include pulling the first tether end 62 and the second tether end 64 until the first fastener is received in the first hole 15 and the second fastener is received in the second hole 16. [0553] Step 10 may optionally include repeating Step 3 through Step 9 to introduce additional fasteners through additional holes in the bone. [0554] Step 11 may include placing the plate on an exterior surface of the bone so that the plate spans the one or more fractures and the fasteners are received within one or more slots of the plate. The plate may be guided to the exterior surface by receiving the first tether end 62 and the second tether end 64 through one or more slots of the plate. The plate may be placed on the exterior surface of the bone through an open incision and/or through a transverse skin tunnel connecting two vertical soft tissue tunnels. [0555] Step 12 may include securing the plate to the exterior surface of the bone by placing a first locking nut 30 over the first tether end 62 and threading and tightening the first locking nut onto the threaded portion of the first fastener and placing a second locking nut 30 over the second tether end 64 and threading and tightening the second locking nut onto the threaded portion of the second fastener. Optionally, additional locking nuts 30 may be used to engage additional fasteners. [0556] Step 13 may include removing the single tether 60 by pulling it with an endoscopic grasper, or similar instrument, through the VATS portal and/or a trans-intercostal incision.
[0557] Those of skill in the art will recognize that this is only one of many potential methods that may be used to stabilize one or more fractures of a bone. In alternative embodiments, different methods may be used to implant the fracture plating system 100 or other fracture plating systems described above. Further, the method set forth in
