Abstract: A bone harvester and bone marrow removal system. The bone harvester can include a body defining a channel extending longitudinally therethrough from a distal to a proximal portion of the body. The distal portion can include a cutting tip. Bone marrow may be drawn through the channel.

Abstract: A bone cutting guide may include a support that contains a shaft movable relative to the support. The shaft may carry a guide member having one or more cut guides through which a clinician inserts a cutting member to cut bone positioned under the guide cut guides. In operation, a clinician may fixate the support of the bone cutting guide to a bone and translate the guide member until the one or more cut guides are positioned at a desired cut location. The clinician may then perform a cut through the cut guide. In some examples, the bone cutting guide includes additional components, such as bridging member or secondary cut guide, to provide additional functionality.

Abstract: In some examples, a method for preparing one or more bones involves inserting a spacer into a space defined between a first bone and a second bone, such as a joint space between a first metatarsal and medial cuneiform. A bone preparation guide can be aligned with opposed ends of the first bone and the second bone using the spacer as an alignment reference. For example, the bone preparation guide may include an opening such that the guide can be installed across the joint space with the spacer received in the opening. A clinician may use the bone preparation guide to guide a tissue removing instrument to cut or otherwise prepare the ends of the first bone portion and second bone portion.

Abstract: A technique for correcting a bone deformity, such as a bunion, may be performed using a fulcrum. In some examples, the technique involves inserting a fulcrum between a first metatarsal that is anatomically misaligned with respect to a second metatarsal. The technique further includes preparing an end of the first metatarsal and preparing an end of a medial cuneiform opposing the end of the first metatarsal. In addition, a distal portion of the first metatarsal is moved toward the second metatarsal in a transverse plane, thereby pivoting a proximal portion of the first metatarsal about the fulcrum and reducing an intermetatarsal angle between the first metatarsal and the second metatarsal.

Abstract: A bone positioning guide may include a main body member, a shaft, and a bone engagement member. The shaft can be movably connected to the main body member and have the bone engagement member rotatably coupled to its distal end. The bone engagement member can have a surface configured to engage a bone. The main body member can also include a tip opposite the bone engagement member for engaging a second bone. In use, the bone engagement member may be positioned in contact with a medial side of a first metatarsal while the tip is positioned in contact with a lateral side of a different metatarsal, such as a second metatarsal. The shaft can then be moved to advance the bone engagement member toward the tip, causing realignment of the first metatarsal.

Abstract: A bone cutting guide may include a support that contains a shaft movable relative to the support. The shaft may carry a guide member having one or more cut guides through which a clinician inserts a cutting member to cut bone positioned under the guide cut guides. In operation, a clinician may fixate the support of the bone cutting guide to a bone and translate the guide member until the one or more cut guides are positioned at a desired cut location. The clinician may then perform a cut through the cut guide.

Abstract: An intra-osseous support structure can be used to fixate opposed portions of bone. In some examples, the intra-osseous support structure is positioned in openings formed in adjacent portions of bones. Fasteners are inserted through the bone portions to secure the intra-osseous support structure in the bones. Depending on the application, one or more external bone plates may also be applied to the bone portions. The external bone plate may be in compression while the intra-osseous support structure is in tension under load in situ.

Abstract: A bone plate kit may be provided for a foot or ankle orthopedic procedure, such as a lapidus procedure. In some examples, the bone plate kit includes a sterile container that holds multiple unicortical bone plate fasteners and one or more bone plates. For example, the kit may contain two bone plates configured to be used together during a tarsal-metatarsal fusion procedure. Each of the two bone plates may be configured to span different regions of a tarsal-metatarsal joint. The unicortical bone plate fasteners can be used to secure the two bone plates to the first metatarsal and medial cuneiform of a patient undergoing a procedure. In some configurations, one of the bone plates is a helical bone plate while the other bone plate may or may not be a helical bone plate.

Abstract: Instruments and surgical techniques may be used to correct a bone deformity, such as a bunion in which a metatarsal is misaligned with respect to a medial cuneiform. In some examples, a bone cutting guide is utilized to cut an end of the metatarsal and/or an end of the medial cuneiform to facilitate realignment of the bones. The cutting guide can have a pivotable cut guide surface along which a cutting instrument is translated to provide a precise bone cut. In some applications, after suitably preparing and aligning the bones, the bones are compressed together using a fixation pin. The fixation pin can be driven through one of the bones, into the second bone, and then further driven to compress the bones together.

Abstract: A method and apparatus for preparing a bone graft composite using an infusion chamber. A modular tube having a porous material contained therein and having removable end caps is provided. Bone marrow aspirate or other bone morphogenic protein containing suspensions may be infused into the tube. A filter on one end of the tube prevents the fluid from escaping while permitting air to be expelled from the tube as it is filled with bone marrow aspirate. Once infused into the tube, the bone marrow aspirate is allowed to settle to a putty or paste-like consistency, the putty and material together forming a bone graft composite.

Abstract: A bone plating system for fixating distal or proximal ends of long bones includes a bone plate having a head portion and a shaft portion, and a plurality of bone screws, at least one of which is a locking bone screw and at least one non-locking cancellous bone screw. The bone plate has a plurality of plate holes in the head portion and a plurality of plate holes in the shaft portion. The head portion or the shaft portion of the bone plate may have a plurality of threaded plate holes for engaging the at least one locking bone screw and at least one non-threaded plate hole for engaging the non-locking cancellous bone screw. The non-locking cancellous bone screw and the at least one non-threaded plate hole are configured and dimensioned to have a particularly useful dimensional relationship.

Abstract: A medical ventilation tube for placement in an opening formed in an anatomical structure, such as the tympanic membrane of the ear, includes a hollow tubular shaft made of a first material having a hardness or durometer to maintain a passage through the shaft when the medical ventilation tube is placed in the opening, and a flange made of a second material having a hardness or durometer less than that of the first material to permit the flange to deform in response to contact with the anatomical structure during removal of the medical ventilation tube from the opening.
