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.

A system is disclosed for repairing and reconstructing an injured intra-articular, extra-articular ligament or tendon to a bone. The system includes realigning the axis of a bone, and further includes fixing fragments of a bone together. Novel devices, instruments and methods are disclosed, including a cortical loop for engaging a bundle of soft-tissue and capturing the bundle against a bone surface, an anchor for stabilizing a fractured bone, a guide for directing an orthopaedic blade, and a hinged external jig arranged to position and guide the blade. Methods are disclosed for connecting soft-tissue to a bone and for bone alignment.

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.

A method of preparing a tarsometatarsal joint can include imaging a tarsometatarsal joint of a patient between a metatarsal and a cuneiform to determine a size and/or angle of a wedge-shaped bone portion to be cut at the tarsometatarsal joint. The method can include obtaining a bone preparation guide that includes a first guide surface positionable over the metatarsal and a second guide surface positionable over the cuneiform, where an angle of the first guide surface relative to the second guide surface is selected corresponding to the size and/or angle of the wedge-shaped bone portion to be cut as determined via imaging of the tarsometatarsal joint. The method can include positioning the guide surfaces over the metatarsal and cuneiform and guiding a tissue removing instrument with the guide surfaces to cut an end of the metatarsal and to cut an end of the cuneiform.

A system for providing fixation of first and second bones includes a drill guide that receives a drill bit to create first and second holes in the first and second bones, respectively. Guide pins can be driven into the first and second holes. The guide pins are received by a surgical saw to guide the surgical saw toward a joint between the first and second bones, thereby creating a third hole in each of the bones across the joint. The guide pins are then removed, and an implant can be inserted into the bones, such that a first leg of the implant is disposed in the first hole, a second leg of the implant is disposed in the second hole, and a keel of the implant is disposed in the third hole.

Apparatus and methods are disclosed for correcting deformities in a patient's foot. In one example, a metatarsus adductus is addressed using a pin placement guide that is angulated to be placed in alignment with a cuneiform and a metatarsal, such that the TMT joint can be subsequently cut, and the metatarsal moved into proper alignment. Th pin placement guide can be a variable angle guide, or a kit of fixed-angle pin placement guides can be provided.

A compressor-distractor device may be used during a surgical procedure, such as a surgical procedure to correct a bunion deformity. In some examples, the compressor-distractor includes first and second engagement arms having first and second pin-receiving holes, respectively. The first and second pin-receiving holes may be angled relative to each other. The compressor-distractor may also include an actuator operatively coupled to the first and second engagement arms. In some example uses, a clinician may pin a first surgical device to a patient's bones use a pair of parallel pins. After removing the surgical device over the parallel pins, the clinician may thread the parallel pins through the angled first and second pin-receiving holes of the compressor-distractor, causing the bones to move relative to each other. Thereafter, the clinician may actuate the actuator on the compressor-distractor to move the bones towards and/or away from each other.

A surgical guidance system (SGS) for performing a cruciate pivot osteotomy in canines to treat cranial cruciate ligament disease. The SGS comprises a guide, a jig, and a plate. The guide is first placed over the tibia until it interacts with specific anatomical features of the tibia, thereby marking the proper position for the jig to be placed. After the jig has been secured, a blade defines an osteotomy within a proximal portion of the tibia. A portion of the jig is then cranially rotated providing a rotational correction of the proximal tibia. A compressive force is then applied to the osteotomy by the jig. Next the multiplane locking plate is placed over the osteotomy as dictated by the features of the jig. After initially securing the plate into its correct position, the jig is removed and the plate is then secured to the cranial surface of the tibia.

A patient-specific instrument is disclosed for performing an osteotomy. The patient-specific instrument includes a body that includes a proximal side, a distal side, a medial side, a lateral side, and an inferior side having a bone engagement surface shaped to match at least one of a first surface of a first bone, a second surface of a second bone, a third surface of a third bone, and a fourth surface of a fourth bone of adjacent joints. The instrument also includes a superior side having one or more guide features that are positioned to guide resection of at least one of the first bone, the second bone, the third bone, and the fourth bone. The body is configured to seat transverse to the adjacent joints with the bone engagement surface engaging at least one of the first surface, the second surface, the third surface, and the fourth surface.

Systems and methods for performing an osteotomy are presented. Examples include forming a fusion osteotomy at a metatarsocuneiform joint of the first ray of a human foot.
