Disclosed are sterile instruments and instrument kits for use in surgery, said instruments including a reamer assembly comprising a reamer depth stop and a reamer, a grommet placer instrument, and a sizing instrument for use in joint implant surgery. The invention also concerns a kit for use in joint implant surgery, comprising said reamer assembly, said grommet placer instrument, a wire guide, comprising a wire guide body, and a guide wire. A method for using one or more of the instruments and kit as described herein is also provided.

A procedure and device that resolves CMC arthritis by mimicking a thumb CMC joint fusion, while avoiding common shortcomings of the fusion surgery as well as existing alternative surgeries for thumb CMC arthritis which can also replace the trapezium bone in the carpometacarpal joint with a stemmed trapezial implant. In addition, the trapezial implant device replicates skeletal anatomy and is configured to directly contact native bone and cartilage in order to more evenly distribute stresses.

A bone cut guide includes a first portion having a first cut slot and having an aperture for receiving a wire to connect the first portion to a first bone. A second portion has a second cut slot and a second aperture for receiving a second wire to connect the second portion to a second bone. The first portion and the second portion are movably connected to each other to allow the first bone and the second bone to move relative to each other.

Apparatus and methods are described for use in securing a first bone relative to a second bone using a pair of surgical staples or, alternatively, a surgical staple and a bone screw. When a pair of staples are used, one of the legs of one of the staples may pass between the legs of the another of the staples. When a staple and a bone screw are used, the bone screw may pass between the legs of the staple. A guide tool can be used during the drilling of the holes for the legs of the staples or the legs of the staple and a bone screw. The guide tool provides guides for drilling guide holes for the staples or for the screw and staple. The guides can be fixed relative to each other during drilling of the guide holes.

Thumb carpometacarpal (CMC) joint implants include a trapezium implant defining an articulating surface and a cooperating first metacarpal implant with a base portion of the first metacarpal defining an articulating surface. The first metacarpal base articulating-surface is configured to articulate against the trapezium implant articulating surface.

A guide assembly for facilitating placement of a fixation member within a medullary canal of a radius is provided. According to one embodiment, a guide assembly includes a guide fastener configured to attach to a fixation member and a guide member configured to receive the guide fastener such that the guide member is secured to the fixation member. The guide assembly also includes an interchangeable distal guide member configured to engage and be disengaged from the guide member. The distal guide member defines a plurality of fastener guide openings for guiding respective fasteners through a plurality of fastener openings defined in the fixation member.

A fusion implant and fusion members for fusing target bones of an upper extremity. The fusion implant including internally threaded apertures of a first thread lead, and the fusion members including threading of the first thread lead and threading of a second thread lead that is less than the first thread lead. The fusion implant and a targeting instrument being configured to couple to one another in a predefined orientation. The predetermined orientation resulting in alignment of aspects of the fusion implant with aspects of the targeting instrument. A guide clamp for facilitating forming of an implant cavity in adjacent bones for implantation of the fusion implant therein. A surgical method for facilitating fusion of adjacent target bones utilizing a fusion implant, fusion members, a targeting instrument and a guide clamp to reduce space between the adjacent bones such that they at least abut one another.

An orthopedic plate is specifically configured for use in osteotomies, in which part of the plate extends into a portion of a first bone segment and part is external to the cortical surface of an adjacent bone segment to fix the segments to allow them to fuse. The plate has a first end and a second end where the end which is inserted into the bone has a chamfer and a through hole having a hole axis optionally at an oblique angle to the longitudinal axis of the plate, and which can receive a screw, peg or pin. The second end of the plate includes a locking screw hole and optionally including a compression slot extending in a direction toward a screw hole in the opposing end. Optionally, the non-locking hole has a shroud that forms an arc or portion of a cylinder over the hole. A plate driver having a recess that holds the plate is used to insert the plate into the bone.

A method for applying compression to a joint includes providing an intramedullary fixation assembly having a proximal screw member positioned at a proximal end of the intramedullary fixation assembly and a lag screw member positioned at a distal end of the intramedullary fixation assembly. Medullary canals are drilled in a first and second bone and the medullary canals are reamed. The proximal screw member is inserted into the first bone and a drill is used create a dorsal hole in the first bone. The lag screw member is slideably coupled to the dorsal hole and to the proximal screw member and into the second medullary canal. A torque is applied to the lag screw member to apply compression to the joint.

A stabilization device is provided including an axle and a portion that can be affixed to a bone. The device is used to stabilize a joint while allowing motion of the joint along its natural trajectory and it is placed internally in order to prevent pin tract problems. Additionally, methods for using the device are provided that include, in various sequences, inserting the axle into a bone of a joint, adjusting the geometry of the device and attaching the fixable portion to another bone of the joint. The device can be provided as part of a system including an axis trajectory guide useful for locating the axis of rotation of the joint prior to insertion, adjustment and attachment of the device.
