A61B 17/88
A61B 17/80
A61B 17/15

Abstract:

A technique for correcting a bone deformity, such as a bunion, may be performed using an instrument. The technique may include preparing an end of a first metatarsal and preparing an end of a medial cuneiform opposing the end of the first metatarsal. The technique may also include moving the first metatarsal relative to the medial cuneiform. The technique can involve inserting the instrument between a first metatarsal and a second metatarsal.

International Classification:

A61B 17/15
A61B 17/17

A61B 17/66

Abstract:

A bone cutting and joint realignment instrument may include an integrated spacer body, bone preparation guide, and fulcrum body. The spacer body is configured to be inserted into a joint space between a metatarsal and an opposed cuneiform of a foot. The bone preparation guide body is affixed to the spacer body with the spacer body extending downwardly from the bone preparation guide body. The bone preparation guide body can define at least one guide surface configured to be positioned over at least one of the metatarsal and the opposed cuneiform. The fulcrum body may be rotatably coupled to the spacer body within a bounded range of rotation, such as a bounded range of less than 45 degree. The fulcrum body can be configured to be inserted in an intermetatarsal space between the metatarsal and an adjacent metatarsal.

International Classification:

A61B 17/17
A61B 17/88

Abstract:

A metatarsal correction procedure may be performed so as to minimize the length of the surgical incision created during the procedure. A variety of different instruments and/or techniques and facilitate the minimal incision procedure. In some examples, a technique involves making a comparatively small surgical incision to access a tarsometatarsal joint. A metatarsal and a cuneiform separated by the tarsometatarsal joint can be prepared. In addition, the metatarsal can be moved relative to the cuneiform using a bone positioning device having a metatarsal engagement member positioned in contact with the skin of the patient on a medial side of the metatarsal. After moving the metatarsal, a fixation device can be installed across the tarsometatarsal joint to cause fusion. In some examples, a plate holder is attached to a U-shaped bone plate to facilitate plating across the joint through the comparatively small incision.

International Classification:

A61B 17/80
A61B 17/86

Abstract:

A method of applying a bone plate across a tarsometatarsal joint or two different portions of a metatarsal may involve positioning a bone plate across a separation between two bone portions. The bone plate can have at least two fixation holes and a bend between the holes. A locking screw can be inserted through one or both holes that has a head thread and a shaft thread, where the shaft thread has a pitch greater than a pitch of the head thread. The locking screw can be screwed into an underlying bone portion until the bend in the bone plate is deformed.

Abstract:

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.

International Classification:

A61B 17/80
A61B 17/17

Abstract:

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.

International Classification:

A61B 17/15
A61B 17/68

Abstract:

An osteotomy procedure may be performed to correct a misalignment of a bone, such as a bunion deformity. In some examples, the osteotomy procedure involves making a spherical-shaped cut transecting a first metatarsal, thereby forming a first metatarsal portion having a spherical-shaped projection and a second metatarsal portion having a spherical-shaped recess. The method further involves moving the second metatarsal portion in at least two planes relative to the first metatarsal portion, thereby adjusting an anatomical alignment of the second metatarsal portion.
