SYSTEMS AND METHODS FOR INTRAMEDULLARY NAIL IMPLANTATION
Intramedullary nails, systems, and methods. The intramedullary nail may include a generally elongate body extending from a first, distal end to a second, proximal end. The distal end may include one or more openings configured to receive one or more bone anchors that extend transversely through the distal end intramedullary nail, and thereby configured to secure the distal end of the nail. The proximal end may also include one or more openings configured to receive one or more bone anchors that extend transversely through the proximal end of the intramedullary nail, and thereby configured to secure the proximal end of the nail. In some embodiments, the proximal opening may contain one or more relief cuts.
Stent
A stent is disclosed that has an elongated body having a proximal end, a distal end, at least one open spiral channel formed on the exterior surface of the body to provide fluid communication between the proximal end and the distal end. The stent also has a central lumen open at the proximal and distal ends of the stent for the passage of a guide wire. A method for using the stent and a kit containing the stent are also disclosed.
Stent
A stent is disclosed that has an elongated body composed of a bioabsorbable polymer having a proximal end, a distal end, two open spiral channels formed on the exterior surface of the body to provide fluid communication between the proximal end and the distal end. The stent also has a central lumen open at the proximal and distal ends of the stent for the passage of a guide wire. A method for using the stent and a kit containing the stent are also disclosed.
Intramedullary pin, clamp and method of use thereof
An intramedullary pin includes a main body having a proximal boundary and a distal boundary; a curved extension having a degree of curvature of at least 1°, the curved extension being in direct contact with the distal boundary; a distal cap having a cylindrical portion and a rounded portion, the cylindrical portion being in direct contact with the curved extension; a grip element having at least one contour, the grip element being in direct contact with the proximal boundary; and a proximal cap having a flat surface, the proximal cap being in direct contact with the grip element. Also disclosed is a clamp that includes a handle, two blades, a pivot, and a plurality of grasping elements including a notch, at least one protrusion, and a groove, where one or more grasping elements have a contour that is structurally complementary to the grip element in the intramedullary pin. A method of immobilizing a bone fracture using the intramedullary pin and/or clamp is also disclosed.
Surgical systems, kits and methods for setting bone segments
An intramedullary nail system is provided with at least one resilient, elongate nail body configured to extend axially along a medullary bone cavity, and at least one bone anchor. The bone anchor includes a distal bone engagement portion configured to secure the anchor to a bone, a proximal nail engagement portion configured to receive a portion of the nail body therethrough, and a tightening mechanism configured to move from a movable state in which the nail body may slide axially and rotate through the engagement portion and a fixed state in which the nail body is prevented from moving relative to the engagement portion. Methods of use and surgical kits are also provided.
SURGICAL DEVICES FOR SMALL BONE FRACTURE SURGERY
Small bone surgical nail devices and methods for use m small hone fracture surgeries, for example, clavicle fracture surgery. The systems and methods can include a nail device with specific design features including, but not limited to differing designs, geometries, and configurations in multiple zones of the device, an associated optional end cap, and/or optional locking screws.

In some embodiments, the proximal end may further include a cross-locking feature, which includes a second bone anchor that interlocks with a first bone anchor, for example, for enhanced bone purchase and bony fixation.
Systems and methods for Lapidus repair of bunions
Systems, devices, and methods for performing Lapidus bunionectomy procedures are disclosed. An example method includes inserting a plurality of metatarsal pins into the first metatarsal at a first predetermined spacing relative to the first tarsometatarsal (TMT) joint, excising the first TMT joint by cutting the bases of the first metatarsal and the first cuneiform proximate the first TMT joint, inserting a plurality of cuneiform pins into the first cuneiform at a second predetermined spacing relative to the first TMT joint, compressing the first TMT joint using a compressor block such that a cut face of the first metatarsal contacts a cut face of the first cuneiform, and fixing the first TMT joint using a bone plate and a plurality of bone screws. At least one of the plurality of bone screws may be a cross screw extending at an angle of less than 90 degrees relative to the bone plate and may anchor the resected first TMT joint to the second metatarsal or the second cuneiform to prevent recurrence of the bunion.
BONE NAIL
Bone nail (1) with a front portion (2), suitable for insertion into the bone and having a free end (3), a rear portion (5) having a free end (6), an outer surface (4); and a nail axis (7); wherein the rear portion (5) has a through hole (8) with a central axis (12) and with an inlet opening (9) located at the rear free end (6) and an outlet opening (10) located on the outer surface (4) of the rear section (5) whereby the through hole (8) is formed for receiving a polyaxial bone screw (11).
