20080317812 | SPACER WITH A COATING THEREON FOR USE WITH AN IMPLANT DEVICE - The present invention relates to a spacer, such as a polymeric spacer, for use with an implant device, e.g., a bone plate, for splinting a fracture of a bone. The spacer includes a body defining a bone healing surface, wherein at least a portion of the bone healing surface has a coating which includes a therapeutic agent, a polymeric carrier, and a buffer medium to stimulate bone growth and/or promote fracture healing. A kit is also disclosed which includes one or more of the spacers, at least one bone plate, and optionally one or more bone screws for securing he bone plate to bone. A method for promoting fracture healing in bone is further disclosed which includes securely situating a coated portion of the spacer adjacent bone. | 12-25-2008 |
20090053673 | METHOD FOR LOCALIZED TREATMENT OF PERIODONTAL TISSUE - A method for localized treatment using a microneedle array to controllably administer a dose of a bone anabolic drug localized at a dental implant site. The bone anabolic drug enhances alveolar bone growth at the dental implant site. Examples of drugs that may be used include, but are not limited to, bone anabolic drugs (e.g., bone morphogenetic proteins, fibroblast growth factor 2, statins parathyroid hormone), and/or drugs that target cell signalling pathways involved in the regulation of the osteoblastic lineage and function. In one embodiment, the method includes monitoring the dental implant site for periodontal tissue generation sufficient to support a dental implant. When sufficient tissue is generated, the dental implant is surgically inserted in the dental implant site. Additional doses of the bone anabolic drug may be delivered prior to detecting tissue generation. | 02-26-2009 |

20130096618 | BONE ANCHOR ASSEMBLIES - A bone anchor assembly includes a bone anchor, a receiver member for receiving a spinal fixation element to be coupled to the bone anchor, and a closure mechanism. The closure mechanism is positionable between the arms of the receiver member to capture a spinal fixation element within the receiver member and fix the spinal fixation element with respect to the receiver member. The closure mechanism includes an outer thread engageable with an inner thread on the arms of the receiver member. The inner thread and the outer thread have a thread angle between 5° and 25°. | 04-18-2013 |
20140277158 | BOTTOM-LOADING BONE ANCHOR ASSEMBLIES AND METHODS - Bone anchor assemblies and methods are provided having a multi-component bone anchor that is configured to allow the shank of the bone anchor to be bottom loaded into a receiver member. In one embodiment, a bone anchor assembly is provided having a shank with a distal threaded portion and a proximal head portion, a ball having a spherical exterior surface and a central lumen sized to receive the head portion of the shank, and a clip configured to be engaged between the head portion and the ball such that the clip is effective to lock the ball in engagement with the shank. | 09-18-2014 |
20140277159 | BOTTOM-LOADING BONE ANCHOR ASSEMBLIES - Bone anchor assemblies are disclosed herein and include bone anchors, receiver members, and closure mechanisms. In one embodiment, a receiver member can be configured to seat a portion of a bone anchor and to receive a spinal fixation element, such as a rod. In an exemplary embodiment, the receiver member is bottom-loading and can include a seat having an opening that can be selectively increased and decreased in size so as to allow a bone anchor to be bottom-loaded. A force can be applied to the receiver member to increase a size of the opening, allowing a portion of the anchor to pass through the opening and into the seat. A closure element can be coupled to the receiver member and can apply a force to decrease a size of the seat and a size of the opening, angularly fixing the receiver member relative to the bone anchor. | 09-18-2014 |
