    摘要： Implant assemblies for reverse shoulder arthroplasty are disclosed. In one embodiment, the implant assembly comprises a humeral component, an adaptor fixed to the neck of the humeral component, and a glenosphere bearing component coupled to the adaptor. The glenosphere bearing component comprises a first bearing surface that interfaces with an articulating surface of the adaptor to allow the adaptor to rotate relative to the adaptor and humeral component. The adaptor and the glenosphere bearing component form a locking mechanism that prevents the adaptor from decoupling from the glenosphere bearing component while allowing the adaptor to remain rotatable relative to the glenosphere bearing component after the implant assembly is implanted in the patient The second bearing surface is configured to interface with a glenosphere component to allow the glenosphere bearing component to articulate relative to the glenosphere component.

    摘要： A prosthetic stem is configured to reduce the perioperative and intraoperative risk of catastrophic medical complications and death that may be caused by BCIS. The prosthetic stem includes one or more internal channels that are configured to self-regulate intramedullary pressure within a prepared bone channel as the stem is inserted into the channel, thus reducing the likelihood of BCIS without sacrificing biomechanics and maintaining a reliable and repeatable implantation process. The stem includes a head and a body, wherein the head is configured to serve as a joint replacement and the body is configured for insertion into the prepared bone channel of a patient. One or more internal channels in the stem are configured to control the pressure within the prepared bone channel during insertion of the stem into the channel, particularly by forming a path through which excess cement may flow as the stem proceeds into the prepared bone channel. By so limiting pressurization of cement during this process, the risk of BCIS complications and other potential harmful effects are reduced while still maintaining sufficient fixation of the prosthetic stem in the prepared bone channel.

    摘要： Described herein are cords (or sutures) and methods for using cords wherein the cords comprise a synthetic aromatic polyamide (or aramid) polymer, wherein the cords comprise a core of a high-strength material such as a polymer (e.g., PET), aramid, ceramic, or metal with a coating of ePTFE encapsulating the core, or wherein the cords comprise braided strands of ePTFE. The disclosed cords have higher strength and durability than typical ePTFE cords or sutures. Furthermore, disclosed herein are methods that utilize the disclosed cords in cardiac repairs, thereby resulting in repairs that are superior to repairs that utilize typical ePTFE cords.
