20090088862 | STEM EXTENSION AND ADAPTOR FOR USE WITH A KNEE ORTHOPAEDIC IMPLANT - An orthopaedic implant includes a knee prosthetic component, adaptor, and stem extension. The adaptor includes a first mounting end and a second mounting end. The first mounting end is coupled to the knee prosthetic component, and the second mounting end is coupled to the stem extension. The first mounting end of the adaptor defines a first axis, and the second mounting end of the adaptor defines a second axis. The first axis is offset from and parallel to the second axis when viewed in a first anatomical plane. Additionally, the first axis and second axis define an angle therebetween when viewed in a second anatomical plane. In some embodiments, the second mounting end may be movable with respect to the first mounting end. In other embodiments, the adaptor may be integral with the stem extension. Additionally, in some embodiments, the adaptor may be embodied as multi-piece adaptor. | 04-02-2009 |
20100114323 | KNEE PROSTHESIS KIT WITH WINGED SLEEVES AND MILLING GUIDE - A knee prosthesis kit includes single-winged and double-winged metaphyseal sleeve components. A milling guide and reamers in the kit allow for a cavity to be prepared to receive the metaphyseal sleeve components by pivoting one of the reamers on a portion of the milling guide. The instruments allow the cavity to be aligned with the intramedullary canal regardless of the relative hardness of the bone in the vicinity of the cavity. | 05-06-2010 |

20130172850 | APPARATUS AND METHOD FOR DISPENSING BONE CEMENT - An apparatus and method for dispensing bone cement includes a cartridge for containing the bone cement. The apparatus also includes a plunger insertable into the cartridge. An impedance sensor is coupled to the plunger and configured to produce an output signal indicative of an impedance of bone cement contained in the cartridge. The apparatus may also include a processing circuit configured to determine an impedance value of bone cement contained within the cartridge based on the sensor signal. The processing circuit may activate a visual indicator based on the impedance value to indicate that the dough time, the end-of-work time, and/or setting-time of bone cement contained in the cartridge has been reached. | 07-04-2013 |
20140081408 | FEMORAL KNEE PROSTHESIS SYSTEM WITH AUGMENTS AND MULTIPLE LENGTHS OF SLEEVES SHARING A COMMON GEOMETRY - A modular knee prosthesis system includes a femoral component having a stem, a plurality of different sizes of sleeves mountable on the stem, and a plurality of different sizes of augments mountable on the femoral component. The system is modular, and provides the surgeon with the option of distally offsetting the joint line by selecting the size of sleeve that will provide the desired joint line. The different sizes of sleeves have different axial lengths but share a common geometry along a substantial part of their lengths so that the same bone cavity will accept multiple sizes of sleeves. | 03-20-2014 |
20140081409 | KNEE PROSTHESIS SYSTEM WITH STANDARD AND DISTAL OFFSET JOINT LINE - A modular knee prosthesis system includes a femoral component having a stem and a sleeve. The system is modular, and provides the surgeon with the option of distally offsetting the joint line by controlling the relative axial positions of the stem and the sleeve. Alternative options include providing sleeves with tapered bores of different diameters, providing a shim to be placed between the sleeve and the stem and providing the stems as adapters having different diameters. | 03-20-2014 |
20140081410 | MODULAR KNEE PROSTHESIS SYSTEM WITH MULTIPLE LENGTHS OF SLEEVES SHARING A COMMON GEOMETRY - A modular knee prosthesis system includes a femoral component having a stem and a plurality of different sizes of sleeves mountable on the stem. The system is modular, and provides the surgeon with the option of distally offsetting the joint line by selecting the size of sleeve that will provide the desired joint line. The different sizes of sleeves have different axial lengths but share a common geometry along a substantial part of their lengths so that the same bone cavity will accept multiple sizes of sleeves. | 03-20-2014 |
20140081411 | SURGICAL INSTRUMENT SYSTEM WITH MULTIPLE LENGTHS OF BROACHES SHARING A COMMON GEOMETRY - An orthopaedic surgical instrument system includes a first broach including a first end configured to be separately secured to a handle and a tapered body having a plurality of cutting teeth defined therein, and a second broach including a first end configured to be separately secured to the handle in place of the first broach, a first tapered body extending distally from a second end positioned opposite the first end, and a second tapered body extending distally from the first tapered body. The tapered body of the first broach and the first tapered body of the second broach have a first outer geometry and the second tapered body has a second outer geometry different from the first outer geometry. | 03-20-2014 |
