20090248024 | INTRAMEDULLARY DEVICE ASSEMBLY AND ASSOCIATED METHOD - An intramedullary device assembly is provided for repairing defects of a bone. The intramedullary device assembly includes a device that is configured to be inserted into the medullary canal of the bone. The assembly also includes a guide adapter that attaches to the end of the device and includes a movable and adjustable bone engagement member. Also a compression member may be attached to the guide adapter that pushes the bone engagement member into engagement with the bone. The bone engagement member defines at least two bone engagement points and wherein at least one bone engagement point is movable relative to at least one other bone engagement point in the direction of the bone. The compression member forces the bone engagement member in the direction of the bone along the bone engagement member guide and the at least one bone engagement point is permitted to move relative to the other at least one bone engagement point so that both bone engagement points can engage the end of the bone as compression is applied to the bone. The guide adapter and compression member may then be detached from the intramedullary device. A breakaway stud may also be included to connect the guide adapter to the intramedullary device such that the application of force on the assembly may break the breakaway stud and detach the guide adapter and compression member from the installed intramedullary device. | 10-01-2009 |
20120215222 | COMPRESSIBLE DEVICE ASSEMBLY AND ASSOCIATED METHOD FOR FACILITATING HEALING BETWEEN BONES - A method of applying compression between a distal bone portion and a proximal bone portion using an orthopedic device is provided. The method may include inserting the orthopedic device through the proximal bone portion and into the distal bone portion, where the orthopedic device includes a core and a sleeve. The method may further include fastening the core to the distal bone portion and fastening the sleeve to the proximal bone portion. The method may further include applying initial compression between the distal bone portion and the proximal bone portion. The method may further include maintaining compression between the distal bone portion and the proximal bone portion with a pawl member. The method may also include allowing for dynamic compression between the distal bone portion and the proximal bone portion after the initial compression has been achieved and maintaining the dynamic compression between the distal bone portion and the proximal bone portion with the pawl member. | 08-23-2012 |
20120265201 | INTRAMEDULLARY DEVICE ASSEMBLY AND ASSOCIATED METHOD - An intramedullary device for repairing defects of a bone is provided. The intramedullary device is configured to be inserted into the medullary canal of a bone and includes a stud protruding from the end. The stud includes a portion that is tapered from a first cross-sectional area to a second cross-sectional where the second cross-sectional area is smaller than that of the first cross-sectional area and the second cross-sectional area defines a region of concentrated stress. The stud also includes a portion configured to engage the internal threads of a fastener retained within an intramedullary device assembly, such as a guide member adapter. The external threads of the stud engage the internal threads of the fastener to secure the intramedullary device to the intramedullary assembly when a first torque is applied to the fastener. | 10-18-2012 |
