DEVICES AND TECHNIQUES FOR TREATING METATARSUS ADDUCTUS

A metatarsus adductus technique may involve cutting an end of one or both of a second metatarsal and an intermediate cuneiform to create a wedge-shaped opening between the end of the second metatarsal and the intermediate cuneiform. The method may further involve cutting an end of one or both of a third metatarsal and a lateral cuneiform to also create a wedge-shaped opening between the end of the third metatarsal and the lateral cuneiform. The second metatarsal and the third metatarsal can then be moved in a transverse plane to close a metatarsus adductus angle. Movement of the second and third metatarsal may close the wedge-shaped openings forming during bone cutting. With the second and third metatarsals appropriately realigned, the clinician can fixate the moved position of the second metatarsal and the third metatarsal.

Bone cutting guide

Provided is a Bone Cutting Guide (BCG) for facilitating the cutting of a patent's bones that may include an outer shell, comprising an upper shell; and a lower shell; a left guidance sphere, comprising a first plurality of pin guidance holes; and a first guide surface; a right guidance sphere, comprising a second plurality of pin guidance holes; and a second guide surface, wherein the left and right guidance spheres are positioned between the upper and lower shells; and a plurality of fasteners configured to hold the upper and lower shells together and, when tightened, secure the left guidance sphere and right guidance sphere into selected positions.

Process, kit, and implant for correction of a bone injury

There is a process for correcting a bone injury, an implant for correcting the bone injury and a kit for applying the implant for correcting the bone injury. The process can be made substantially uniform with the application of a standardized kit. In at least one application the process is for correcting a bunion on a patient. The process can include applying a first drill guide to a bone, and then a second drill guide. Once the drill guides have been applied and wires have been inserted into a bone, an implant can then be applied to correct a bone injury and to allow the bone injury to heal.

DISTRACTORS HAVING ATTACHABLE PADDLES, IMPACTION DEVICES, AND METHODS FOR USE IN TOTAL ANKLE REPLACEMENT

A distractor system for use in a joint between two bone surfaces of an anatomical structure includes, for example, distractor and at least one detachable tool comprising a body having a proximal portion and a distal portion, said proximal portion being releasably attachable to at least one of a first end of the distractor and/or a second end of the distractor. The distal portion of the detachable tool being operably positionable in the joint between the two bone surfaces of the anatomical structure. The detachable tools may include a detachable paddle.

POLYAXIAL DRILL GUIDE

An orthopedic drill guide assembly is disclosed. The assembly can include an elongated shaft having a proximal end and a distal end, and a first guide member that includes a bonecontacting surface and a second surface opposite the bone-contacting surface. The first guide member is provided at the distal end of the elongated shaft. The first guide member includes one or more guide holes that are configured for receiving a drill bit at an angle that can vary from 0 to 30 degrees from orthogonal of the bone-contacting surface.

CHAMFER GUIDANCE SYSTEMS AND METHODS

A surgical tool includes a handle and a trial section coupled to the handle by an engagement section. The trial section includes an upper surface and a lower surface. The upper surface has a shape that corresponds to an upper surface of an implant. The trial section defines a first slot extending from the upper surface to the lower surface and inwardly from a first side. A second slot extends from the upper surface to the lower surface and inwardly from a second side.

Ankle fusion system with expandable spacer
11612490 · 2023-03-28 · ·

System, including apparatus and methods, for ankle fusion using a device for separating a first bone and a second bone of an ankle region. In some embodiments, the device may comprise an expandable spacer including first and second bone-contacting surface regions facing away from one another and configured to be abutted with the first and second bones, respectively. A distance between the first and second bone-contacting surface regions may be adjustable to change the separation of the first and second bones. The first bone-contacting surface region may correspond to a portion of a sphere and may be configured to be disposed at least partially in a concavity formed surgically in the first bone. The expandable spacer offers improved control over the length of the lower limb and the orientation of the foot during ankle fusion surgery.

Patient-specific bridging plates

Disclosed herein are a bone plating system and a method for utilizing the same. The bone plating system may include first and second bone plates in contact with respective first and second bones, a cross-connector, a cutting guide and a targeter device. The cross-connector may have a first end and an opposite second extending along a longitudinal axis from the first bone plate to the second bone plate. The cutting guide may have an elongate body placed on one of the first or second bones. The targeter device may have a drill guide to align the cross-connector with the first and second bone plates. A method for fixing the bone plating system to the first and second bone may include using the targeter device.

PATIENT-SPECIFIC INSTRUMENTS FOR PERFORMING BONE CUTS

An apparatus and a method are provided for a patient-specific instrument guide for arthroplasty or other operations on bone tissue, capable of limiting bone cuts, achieving optimal implant positioning, and providing improved stability of implants. The patient-specific instrument guide comprises a body that includes a bone contact surface configured to contact a bone surface of a patient. The body is configured to be 3D printed according to medical imaging of a patient's anatomy, such that the bone contact surface optimally contacts the surface of the patient's bone. The body includes one or more guide slots that each slidably receives a cutting guide. The cutting guides are configured to receive a saw blade during bone cutting. The cutting guides may be oriented to guide cutting a talus or a tibia during a total ankle arthroplasty surgery.
