The diaphyseal portion defines a longitudinally extending first surface of the diaphyseal portion. The first surface defines a longitudinally extending first void. The first epiphyseal portion extends from the diaphyseal portion. The first epiphyseal portion is configured for placement in the medullary canal of the first epiphysis of the long bone. The nail also includes a first insert positioned in the longitudinally extending first void of the diaphyseal portion. The first insert and the diaphyseal portion of the body are made from different materials. | 04-02-2009 |
20090088768 | Apparatus for measuring an angle of a guide wire relative to a bone - A measurement apparatus has a body that includes a reference surface that defines a reference line. The body further includes a first elongate window defining a first measurement line and a first measurement indicia positioned in association with the first elongate window. The first measurement line and the reference line define a first angle having a first magnitude. The first measurement indicia corresponds to the first magnitude. | 04-02-2009 |
20090088806 | Plate holder assembly having bone plate seating confirmation arrangement - An assembly includes a plate holder having a body. The assembly further includes a stop structure movable in relation to the body between a first location and a second location. In addition, the assembly includes a bone plate assembly including (i) a bone plate having a plurality of fastener openings defined therein, the bone plate being attached to the body, and (ii) a fastener guide. One of the bone plate and the fastener guide includes a channel, and the other of the bone plate and the fastener guide includes a projection configured to be received in the channel. | 04-02-2009 |
20090248025 | Intramedullary nail with coupled shafts - A nail assembly for use in trauma surgery is provided. The nail assembly includes an intramedullary shaft including a first transverse passage and a second transverse passage in the shaft. The, first transverse passage and the second transverse passage do not contact each other on the shaft. The nail assembly also includes a first shaft extending through the first transverse passage in the intramedullary shaft and a second shaft extending through the second transverse passage in the intramedullary shaft. The second shaft includes an engagement feature configured to bring the second shaft into contact with the first shaft. The engagement feature may be in the form of a lateral mechanical feature that provides simultaneous unilateral coupled motion of the first shaft with the second shaft through the transverse passages in the intramedullary shaft. | 10-01-2009 |
20090326534 | Fracture Fixation Apparatus - An apparatus for treating a bone fracture comprises an intramedullary rod extending through a first bone segment of a fractured bone. A lag screw assembly extends through a first transverse aperture in the rod, while a control member extends through a second transverse aperture longitudinally offset from the first aperture. The lag screw assembly includes a lag screw engaged to the second bone segment and a locking sleeve mounted over a proximal portion of the lag screw. The locking sleeve defines a groove aligned with the second aperture. The control member includes a distal portion penetrating the bone segments, an intermediate portion configured to engage the second aperture and an enlarged head configured to slidably engage the groove. The groove includes a terminus that contacts the head of the control member after a predetermined amount of lateral migration of the lag screw as the fracture collapses. | 12-31-2009 |
20090326541 | Targeting Apparatus for Use in a Medical Procedure - A universal targeting apparatus includes a generally U-shaped body having one end configured to be coupled to the proximal end of the intramedullary implant and a mounting portion at an opposite end of said body. An arm is rotatably mounted to the mounting portion of the U-shaped body and includes bores defined at its opposite ends. Each bore is arranged at a different angle to correspond to the angle of a transverse aperture in the intramedullary implant. The arm can be rotated so an appropriate one of the angled bores is aligned with the transverse aperture to serve as a guide for creating targeting holes in the bone. | 12-31-2009 |
20100249781 | INTRAMEDULLARY NAIL WITH LOCKING KEY - An intramedullary nail comprises longitudinal channel, a first transverse passage and a second transverse passage. A lag screw extends through the first transverse passage of the intramedullary nail. An anti-rotation shaft extends through the second transverse passage of the intramedullary nail. A cannulated lag screw lock is positioned in the intramedullary shaft and engages the lag screw. The anti-rotation shaft extends through a cross channel in the lag screw lock. A second shaft lock is positioned in the intramedullary nail with the second shaft lock engaging the anti-rotation shaft. In at least one embodiment, the lag screw lock includes a substantially cylindrical body portion rotatably connected to a threaded head portion. In at least one embodiment, the second shaft lock is provided as an end cap including a threaded upper portion and a lower post portion that extends into the lag screw lock. | 09-30-2010 |
20130030444 | TARGETING APPARATUS FOR USE IN A MEDICAL PROCEDURE - A universal targeting apparatus includes a generally U-shaped body having one end configured to be coupled to the proximal end of the intramedullary implant and a mounting portion at an opposite end of said body. An arm is rotatably mounted to the mounting portion of the U-shaped body and includes bores defined at its opposite ends. Each bore is arranged at a different angle to correspond to the angle of a transverse aperture in the intramedullary implant. The arm can be rotated so an appropriate one of the angled bores is aligned with the transverse aperture to serve as a guide for creating targeting holes in the bone. | 01-31-2013 |
20140276826 | TARGETING GUIDE FOR AN INTRAMEDULLARY NAIL - A targeting instrument system for positioning an intramedullary implant. The system comprises a multi-use targeting guide arm, an intramedullary implant, and a single-use nose segment configured to maintain a locking alignment between the intramedullary implant and the targeting guide arm during the placement of the intramedullary implant into a subject. The system may be provided as a sterile kit, and the intramedullary implant may be preassembled to the nose segment. Alternatively, system may include a sterile kit comprising a single-use targeting guide arm, and an intramedullary implant, wherein the intramedullary implant is preassembled to the single-use targeting guide arm. | 09-18-2014 |
20140276878 | INTRAMEDULLARY NAIL HOLDING DEVICE - A targeting instrument system is provided and methods for positioning an internal fixation prosthesis, such as an intramedullary rod or nail, including a targeting guide device, an internal fixation prosthesis, and a detachable holding device. The holding device may include an exterior grip portion and a clamp portion defining an interior engaging surface for maintaining a locking alignment between the prosthesis and the targeting guide device during the placement of the internal fixation prosthesis into a subject. The holding device may be formed as a monolithic component including at least two flexible, spaced apart arms defining an elongated receiving channel extending from a proximal end configured to releasably engage the prosthesis and a distal end configured to releasably engage the targeting guide device. Alternatively, the holding device may include two pivotally coupled clamp bodies joined by a shaft rod. | 09-18-2014 |
