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 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.
POSITIONING AND ALIGNMENT INSTRUMENT FOR INTRODUCING SURGICAL DEVICES INTO BONE
A positioning and alignment instrument, and methods of use thereof, are provided for facilitating the alignment and insertion of a device, such as a guide wire, into bone. The instrument includes a handheld anchoring component and a rotatable guidance component. During use, the anchoring component is anchored into bone via anchoring protrusions, such that the position and orientation of the anchoring component is fixed relative to the bone. The guidance component, which is mechanically supported by the anchoring component, includes a device guide channel for receiving the device and guiding the device towards an insertion location adjacent to the distal end of the anchoring component. The guidance component is rotatable relative to the anchoring component about a rotation axis that is located adjacent to the distal end of the anchoring component, such that the insertion location remains adjacent to the distal end of the anchoring component under rotation.
SUPRAPATELLAR INSERTION SYSTEM, KIT AND METHOD
A system is provided for inserting and securing, through a suprapatellar region of a leg, a nail into a medullary canal of a bone. The system can include a flexible sleeve configured to be partially inserted in the leg. The flexible sleeve can define a leading end and a trailing end spaced apart from the leading end along a first axis. The flexible sleeve can define a first cannulation that extends along the first axis between the leading and trailing ends. The first cannulation can be sized to receive therethrough at least the intramedullary nail. The system can further include a retaining member configured support at least a portion of the flexible sleeve. The retaining member can be configured to position the flexible sleeve through the suprapatellar region of the leg such that the flexible sleeve leading end is aligned with the proximal end of the bone. The intramedullary nail can be insertable through the flexible sleeve and into the medullary canal.
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.
DEVICE FOR DRIVING FIXATION ELEMENTS INTO BONE AND METHOD OF USE THEREOF
A implanting device for driving a fastener or fixation element into bone is described. Also described are methods for using a implanting device for driving a fastener or fixation element into bone and a kit comprising a pneumatic implanting device for driving a fastener or fixation element into bone.
System and method for treating bone fractures
An intramedullary nail includes one or more nail openings extending therethrough. The intramedullary nail is implantable within a medullary canal of the bone. A bone plate is configured to engage an outer surface of the bone. The bone plate includes one or more plate openings extending therethrough. The plate openings are spaced about the bone plate such that the bone plate is positionable to axially align the plate openings with the nail openings when the intramedullary nail is implanted within the medullary canal of the bone. An aiming guide includes one or more targeting openings. The targeting openings are spaced about the aiming guide such that the aiming guide is positionable to axially align the targeting openings with the plate openings and the nail openings for extending one or more stabilizing fasteners therethrough when the intramedullary nail is implanted within the medullary canal of the bone.
Orthopaedic broach extraction tool
An apparatus, system, and method for extracting an orthopaedic broach from a bone of a patient comprises an orthopaedic broach extraction tool having a pair of jaws that are operable to secure the orthopaedic broach extraction tool to the orthopaedic broach. Once secured, the orthopaedic broach extraction tool can be used to facilitate extraction of the orthopaedic broach from the patient's bone using, for example, a reverse impaction tool.
INTRAMEDULLARY NAIL INSERTION HANDLE
In one embodiment, an intramedullary nail insertion system has a handle, a coupler, and a securement member. The handle has a body that includes a distal body end, and a proximal body end that is spaced from the distal body end along a proximal direction. Further, the handle defines an aperture that extends from the distal body end to the proximal body end. The coupler includes a distal coupler end having a first fastener that fastens to an intramedullary nail, and includes a proximal coupler end having a second fastener sized to be received through the distal body end in the proximal direction into the aperture of the handle. The securement member has a third fastener that fastens to the second fastener of the coupler so as to capture the handle body between the securement member and the intramedullary nail. The system can be assembled using a two-handed operation.
Method and apparatus for treating a bone fracture
Apparatus for treating a bone fracture, the apparatus comprising: an anchoring tube comprising a hollow elongated shaft adapted for disposition in a hole formed in a bone and having a distal end, a proximal end and a lumen extending therebetween, and a substantially planar plate mounted to the proximal end of the hollow elongated shaft and adapted for disposition against the outer surface of the bone; wherein the plate comprises a top surface and a bottom surface, and further wherein the bottom surface of the plate is convex, such that when the anchoring tube is disposed in a hole formed in a bone and is rotated about the longitudinal axis of the hollow elongated shaft, the convex bottom surface of the plate maintains supporting contact with the outer surface of the bone.
Suprapatellar insertion system, kit and method
A system is provided for inserting and securing, through a suprapatellar region of a leg, a nail into a medullary canal of a bone. The system can include a flexible sleeve configured to be partially inserted in the leg. The flexible sleeve can define a leading end and a trailing end spaced apart from the leading end along a first axis. The flexible sleeve can define a first cannulation that extends along the first axis between the leading and trailing ends. The first cannulation can be sized to receive therethrough at least the intramedullary nail. The system can further include a retaining member configured support at least a portion of the flexible sleeve. The retaining member can be configured to position the flexible sleeve through the suprapatellar region of the leg such that the flexible sleeve leading end is aligned with the proximal end of the bone. The intramedullary nail can be insertable through the flexible sleeve and into the medullary canal.
