20130046349 | CONTOURED BONE PLATE FOR FRACTURE FIXATION HAVING HOOK MEMBERS AND HOLDER/IMPACTOR FOR SAME - A bone fixation plate for fixation of fractures having a small terminal bone fragment, such as fractures of the distal radius. The plate includes an elongated body, and two hook members extending from a first end of the elongated body. A contoured region is configured to approximate the surface contour of the distal radius proximate the volar rim, the dorsal rim, or the radial arm. Each hook member is configured to provide subchondral support to a distal bone fragment, without causing shortening of the fragment into the metaphyseal bone, and without providing a bending torque directed to the base of the plate. The tooth members of the hook plate are preferably sharpened at their tips and edges to facilitate their impaction. A holder/impactor for gripping the radial hook plate, and for further facilitating impacting of the hook plate without the need to pre-drill pilot holes, is also provided. | 02-21-2013 |
20130204307 | Distal Radius Fracture Fixation Plate with Integrated and Adjustable Volar Ulnar Facet Support - A volar distal radius plate includes a shaft and a head. The head includes a radial side that seats below the volar rim, and an ulnar side with two extending tabs that provide a buttress support to ulnar fragments from the volar rim. The tabs are contoured to be atraumatic to the overlying soft tissue. The tabs can be readily re-orientated to better approximate the volar rim and provide close support to the volar fragments. Each tab includes a single hole specifically sized to closely receive a K-wire in a fixed angle orientation, and which permits the K-wire to apply a bending load to a tab in situ to bend the tab about a lower recess between the tab and the remainder of the head. Therefore, the plate does not require a dedicated bender. The tabs can also accommodate sutures. | 08-08-2013 |
20130238035 | LOCKING PIN PLATE ASSEMBLY ADAPTED FOR FRACTURE FIXATION - A lockable pin plate assembly which has a pin plate adapted to be secured to stable bone and provided with pin holes for pins for pinning an unstable bone fragment. One or more pin holes are engageable by pins of an integral U-pin. The pins have stop surfaces thereon which are resiliently displaced when the pins are seated to automatically and self-lock the pin and the pin plate to oppose withdrawal and backing out of the pins from the pin plate. In a preferred embodiment, each pin of the U pin has a leading portion and a trailing portion, the leading portion being of smaller diameter to pass freely through an elliptical hole in the pin plate whereas the trailing portion is of larger size to become locked in the pin hole as it is advanced therein. | 09-12-2013 |
20140058456 | Distal Radius Fracture Fixation Plate with Ulnar Buttress - A distal volar fixation plate includes a body portion and a head portion angled upwards relative to the body portion. The head portion includes a lower surface, a central portion, a radial side and an ulnar side. The head portion defines a buttress portion extends greater distally on the ulnar side than on the radial side to support the volar lip of the lunate fossa. | 02-27-2014 |
