A percutaneous method for removing an outer portion of the proximal end of a lag screw protruding from a fractured femur when embedded in the femur to stabilize an intramedullary nail implanted in the intramedullary canal using a multi-part cannulated driver wherein the lag screw comprises a distal section, an intermediate section including a channel formed in the proximal portion thereof with a driver recess formed at the distal end thereof, and a proximal section having a notch, groove or score mark formed on the exterior surface of the lag screw separating or between the intermediate section and the proximal section and the multi-part cannulated driver comprises a cannulated shaft including a first driver member formed thereon configured to engage the driver recess to prevent the distal section and intermediate section of the lag screw from rotating in the femoral head when torque is applied to the proximal section by a second driver member engaging the proximal section of the lag screw to separate the proximal section from the section and the intermediate section along the notch, groove or score mark.

A femoral fixation device may include a shaft and a helical thread disposed about the shaft between a first location and a second location along the shaft. The helical thread may include a concave undercut surface. The femoral fixation device may be configured such that, when the femoral fixation device is implanted within a neck and a head of a femoral bone: the first location, the second location, and the helical thread therebetween may be disposed within the head of the femoral bone; the concave undercut surface may be oriented toward a proximal end of the femoral fixation device; and the concave undercut surface may be configured to transmit at least one force from the head of the femoral bone to the neck of the femoral bone.

The present application provides a new and innovative device for aiding in screw installation through a distal end of a nail installed in a patient's bone (e.g., humerus). The nail's distal end is disposed away from an insertion point of the nail into the bone. The targeting device includes a targeting body having an outer frame, a flexible member connected to the outer frame, a targeting block having multiple holes and connected to the flexible member such that the flexibility of the flexible member enables the targeting block to translate towards sides of the outer frame, and an adjustment assembly that adjusts and maintains the targeting block's position relative to the sides of the outer frame. The targeting device further includes a base plate removably coupled to the targeting body. The targeting device may be coupled to the nail at the base plate.

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.

A bone plate comprises a body including an elongated opening extending therethrough, the opening being open at a distal end of the body and including a distal portion and a proximal portion, the distal portion having a width smaller than a width of the proximal portion, the width being a dimension between two longitudinal sides of the opening extending parallel to a longitudinal axis of the body, the body further including an insert including a head portion and a base portion, the base portion being shaped to be slidably mounted within the proximal portion of the opening, a diameter of the base portion being larger than a width of the distal portion of the opening such that the base portion is prevented from exiting the opening through the distal portion thereof, the insert further including a central fixation element receiving hole configured to receive a bone fixation element therethrough.

One aspect of the invention provides a lag-screw-retaining clip including: a medial flange adapted and configured for engagement medially under a head of a laterally inserted screw of a trochanteric fracture nail system; an axial offset member coupled to the medial flange, the axial offset member including: a first, medial end coupled to the medial flange; and a second, lateral end; and a lateral flange coupled to the second, lateral end of the axial offset member. The lateral flange is adapted and configured to rest against a lateral end of a lag screw of the trochanteric fracture nail system and resist lateral movement of the lag screw.

An intramedullary nail implant for positioning in a bone having a head and a shaft defining an intramedullary canal. The implant includes a distal portion having a shaft extending along a central axis and configured for positioning within the intramedullary canal. A proximal portion extends proximally from the distal portion. The proximal portion defines a contact surface which extends at least in part medially of the central axis such that it is configured to extend within a medial portion of the bone head. A method of implanting the nail is also provided.

Intramedullary systems, expandable intramedullary nails, expandable anchors, and methods of using the same. The intramedullary system may include an expandable intramedullary nail configured to extend into an intramedullary canal of a long bone and/or one or more expandable anchors configured to extend at an angle transverse to the intramedullary nail. The intramedullary nails and/or anchors may include one or more integrated expansion mechanisms that allow for insertion in a contracted configuration and expansion into a deployed configuration to lock the relative position and prevent axial rotation and translation of the system.

A device for fixation of bone fragments (4, 8) comprises a locking plate (1) for fixation on the outside of an outer bone fragment (4). The locking plate has a distal portion (1 a) with at least one first hole (6), extending through the locking plate, for a distal fixing means (2) and a proximal portion (1 b) with a second hole (7), extending through the locking plate, for a proximal fixing means (3). The locking plate (1) is configured also with a third hole (9) which is located between said at least one first hole (6) in the distal portion (1 a) of the locking plate and said second hole (7) in the proximal portion (1 b) of the locking plate and this third hole extends as the other holes through the locking plate. The device further comprises a rotary-preventing and load-carrying means (10) which is configured for inser¬tion and fixation in said third hole (9) in the locking plate (1) and by cooperating with the proximal fixing means (3) prevent rotation of the proximal fixing means but permit displa¬cement thereof in its longitudinal direction relative to the rotary-preventing and load-car¬rying means during compression after surgery of the outer and inner bone fragments (4, 8) and facilitate for the proximal fixing means to carry loading forces acting on the inner bone fragment (8).

A method to secure and stabilize an intramedullary nail in the medullary canal of a fractured hip including the steps of positioning the intramedullary nail within the medullary canal, positioning an alignment tool including a plurality of alignment bores on the intramedullary nail to align drill bits to drill holes or channels in the femur neck, femur cortex and upper and lower portions of the intramedullary nail, threading a femur neck screw through the corresponding alignment bore into a channel in the femur neck, through the hole in the upper portion of the intramedullary nail and into the head, threading a locking screw through the corresponding alignment bore and a hole in the proximal cortex and channel in the lower portion of the intramedullary nail and into the distal cortex, threading a stabilizer member through the corresponding alignment bore until the distal end portion engages the proximal surface of the intramedullary nail to limit lateral movement of the intramedullary nail thereby stabilizing the intramedullary nail in the medullary canal and removing the alignment tool from the upper portion of the intramedullary nail.
