| 20080234829 | HUMERAL HEAD AUGMENT DEVICE AND METHOD FOR USE IN A SHOULDER PROSTHESIS - A humeral head augment device for use in a modular shoulder prosthesis. The humeral head augment device has an external bearing surface with at least one surface portion that includes a radius of curvature. The radius of curvature is configured to constrain translational movement of the implanted shoulder prosthesis when the humeral head augment device is positioned within the shoulder prosthesis. The humeral head augment device also includes a coupling mechanism designed to lock the humeral head augment device to either the stem or the humeral head, thereby ensuring proper operational positioning of the device within the shoulder prosthesis and allowing the implanted shoulder prosthesis to function in a patient suffering from rotator cuff arthropathy. A shoulder prosthesis using a humeral head augment device, a method for assembling a shoulder prosthesis and method for using a humeral head augment device in a shoulder prosthesis are also disclosed. | 09-25-2008 |
| 20090299375 | CATHETER NAIL TARGETING GUIDE - An instrumentation or targeting guide for use with an orthopedic device, such as an intramedullary nail, for example. The guide includes a guide body having a handle portion and a barrel portion. An intramedullary nail is fixedly securable to the barrel portion via a locking bolt. The barrel portion includes at least one canal configured to receive a catheter, the canal aligned with a corresponding canal in the intramedullary nail. In use, a catheter may be inserted over a guide wire and through both the canal in the barrel portion of the guide body and through the corresponding canal in the intramedullary nail prior to insertion of the intramedullary nail into the intramedullary canal of a long bone. In this manner, the placement of the catheter for delivery of medications within in the intramedullary canal of the long bone is facilitated. | 12-03-2009 |
| 20100228352 | GLENOID IMPLANT ANCHOR POST - A prosthesis that mechanically couples with both cancellous bone and cortical bone of a glenoid includes a head portion comprising a rear surface and an articular surface, an anchor member, and a plurality of deformable fins extending radially outward from the anchor member. The anchor member includes a distal end and a proximal end connected to the rear surface of the head portion. The plurality of deformable fins extend radially outward from the anchor member and includes at least a first proximal fin adjacent to the rear surface of the head portion positioned to engage with the cortical bone. The anchor member may also include at least one distal fin located proximate the distal end of the anchor member positioned to engage with the cancellous bone. | 09-09-2010 |
| 20110082557 | Integral, One-Piece Humeral Head Device - A humeral head augment device for use in a modular shoulder prosthesis. The humeral head augment device has an external bearing surface with at least one surface portion that includes a radius of curvature. The radius of curvature is configured to constrain translational movement of the implanted shoulder prosthesis when the humeral head augment device is positioned within the shoulder prosthesis. The humeral head augment device also includes a coupling mechanism designed to lock the humeral head augment device to either the stem or the humeral head, thereby ensuring proper operational positioning of the device within the shoulder prosthesis and allowing the implanted shoulder prosthesis to function in a patient suffering from rotator cuff arthropathy. A shoulder prosthesis using a humeral head augment device, a method for assembling a shoulder prosthesis and method for using a humeral head augment device in a shoulder prosthesis are also disclosed. | 04-07-2011 |
| 20110125155 | HUMERAL HEAD SHAPING DEVICE AND METHOD - Provided is a method and device for shaping a greater tuberosity of a humerus in preparing for receiving a prosthetic humeral head. The device shaves bone from the greater tuberosity such that the greater tuberosity is not resected or completely removed. | 05-26-2011 |
