Arthroscopic surgery method for ankle ligament reconstruction
An arthroscopic surgery method for ankle ligament reconstruction of this embodiment is removed using an ultrasonic treatment tool, blowing away a synovial membrane, and secures the view for a remnant ligament. Then, bone holes are produced to a fibula, a talus and a calcaneus using the ultrasonic treatment tool.
Bone positioning and preparing guide systems and methods
Methods for temporarily fixing an orientation of a bone or bones. Methods of correcting a bunion deformity. Bone positioning devices. Methods of using a bone positioning device. Bone preparation guides. Methods of using a bone preparation guide.
Bone cutting guide systems and methods
A method of correcting an alignment between bones of a foot may involve positioning a first cutting slot of a bone cutting guide over a first metatarsal and inserting a first fixation pin through a first fixation aperture of the bone cutting guide and into the first metatarsal. The method may also involve inserting a cutting member through the first cutting slot to remove a portion of the first metatarsal and adjusting an alignment of the first metatarsal relative to a first cuneiform. In some examples, the method further includes positioning a second cutting slot of the bone cutting guide over the first cuneiform and inserting a second fixation pin through a second fixation aperture of bone cutting guide into the first cuneiform. The method can involve inserting a cutting member through the second cutting slot to remove a portion of the first cuneiform and causing the first metatarsal to fuse to the first cuneiform in the moved position.
BONE REPOSITIONING GUIDE SYSTEM AND PROCEDURE
An improved surgical system and procedure for correcting a deformity between first and second bones using an alignment guide based on a correction factor. The correction factor can be based on a virtual model of the first and second bones in a deformed configuration and a corrected configuration. In the virtual corrected configuration, first and second virtual axes can be fixed in the respective first and second bones. When reverted to the virtual deformed configuration, the orientation of the first and second axes can be used to determine the correction factor. The alignment guide is used to insert one or more k-wires into each of the first and second bones in a deformed configuration. A correction guide is passed along the k-wires to rotate and/or translate the first bone relative to the second bone into the corrected configuration.
Ankle replacement system and method
Various surgical devices and methods are disclosed herein. Also disclosed is multi-component prosthesis, which can be used as an ankle prosthesis. One of the disclosed surgical alignment systems includes a guide arm, a ratchet arm frame configured to be coupled slidably to the guide arm, a ratchet arm configured to be coupled to the ratchet arm frame, and a sagittal sizing guide body configured to be coupled to the ratchet arm. The sagittal sizing guide body includes a first radiopaque object disposed at a first position and a second radiopaque object disposed at a second position that is spaced apart from the first position.
Joint spacer systems and methods
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.
Small joint fixation
A method of joining adjacent bone includes providing a medical device having a first implant portion, a second implant portion attached to the first implant portion, and a driver assembly having an instrument adapted to form an opening in bone. The driver assembly is integrally connected to and removably attached to the second implant portion at a connection, distal from the first implant portion. The driver assembly further has a wire driver extending therefrom, distal from the first implant portion. The method further includes inserting the wire driver into a wire driver tool; placing the first implant portion against a first bone structure; inserting the first implant portion into the first bone structure; removing the second implant portion from the driver assembly; using the driver assembly to form an opening in a second bone structure, adjacent to the first bone structure; and inserting the second implant portion into the opening.
Systems and methods for implanting surgical implants
The present invention relates to an implant system that comprises an implant, a handle configured to removably receive the implant, and, in some embodiments, a spacer tool configured to be mounted on the implant. In further embodiments, a k-wire is employed to guide the implant to a desired location. The handle has a hole for receiving a first portion of the implant. Using the handle to implant the implant, along with an associated spacer, provides a quick and convenient method for implanting the implant as described herein and in the associated drawings.
Joint osteotomy system and method
A system includes a first spacer sized and configured to be received within a resected bone space of a first bone and a second spacer sized and configured to be coupled to a second bone. The first spacer and the second spacer each include a body extending between a bone contacting surface and a coupling surface. At least one shim is positioned between the first and second spacers. The shim includes a body extending between a first coupling surface and a second coupling surface. The first spacer, the second spacer, and the at least one shim position the first and second bones in a predetermined alignment. An adjustable guide including a guide adapter and a guide body is configured to couple to the first spacer and is adjustable on a first axis.
BONE REPOSITIONING GUIDE SYSTEM AND PROCEDURE
A surgical system and procedure are provided for correcting a deformity between first and second bones using an alignment guide based on a correction factor. The alignment guide is used to insert one or more k-wires into each of the first and second bones in a deformed configuration. A correction guide is passed along the k-wires to rotate and/or translate the first bone relative to the second bone into the corrected configuration. An auxiliary correction guide can be passed along the k-wires to further rotate and/or translate the first bone relative to the second bone from the corrected configuration to an adjusted configuration.
