摘要： A surgical instrument includes a movable member having a proximal portion, the movable member defining an opening at the proximal portion. The instrument includes a stationary member defining an aperture. The stationary member is arranged relative to the movable member with a close fit between the stationary member and the movable member such that aspiration occurs through the movable member substantially only during a portion of a repetitive motion of the movable member. The instrument includes a surgical handpiece coupled to the movable member and the stationary member to provide suction and motion to the movable member. A method of regulating aspiration through a surgical instrument includes providing a close fit between a moving member having an opening at a proximal portion and a stationary member having an aperture such that aspiration occurs through the moving member substantially only during a portion of a repetitive motion of the movable member. The moving member and the stationary member are coupled to a surgical handpiece to provide suction and motion to the moving member.

摘要： The present invention relates to the prevention and decrease of osteolysis produced by wear of the ultrahigh molecular weight polyethylene (UHMWPE). Methods are disclosed for the isolation of wear particles, preparation of implants exhibiting decreased wear in comparison to conventional UHMWPE and preparation of implants that cause decreased biological response in comparison to conventional UHMWPE. The implants created by these methods are also included in the present invention.

摘要： An apparatus (10) for ultrasonically treating an injury in conjunction with an orthopaedic cast (288) is disclosed. The apparatus includes a portable self-contained main operating unit (12), a support fixture (110, 520, 590, 610, 632, 672, 708, 824), an ultrasonic transducer treatment head module (14), and casting material for attaching the support fixture (110, 520, 590, 610, 632, 672, 708, 824) to the orthopaedic cast (288). The support fixture (110, 520, 590, 610, 632, 672, 708, 824) is configured and adapted for attachment to the orthopaedic cast (288) adjacent an external site corresponding to an internal injury remote from the main operating unit (12). The support fixture (110, 520, 590, 610, 632, 672, 708, 824) has a body (114) and at least one mesh projection (112, 526) extending from the body (114). The ultrasonic transducer treatment head module (14) is operatively connected to the main operating unit (12) and detachably engaged with the body (114) of the support fixture (110, 520, 590, 610, 632, 672, 708, 824). At least a portion of the casting material impregnates the mesh projection (112) to attach the support fixture (110, 520, 590, 610, 632, 672, 708, 824) to the cast (288).

摘要： The present invention is based, in part, on studies we conducted with biocompatible compositions that contain a copolymer and a filler material. Accordingly, the invention features compositions that include a copolymer (e.g., a copolymer that includes lactic acid and/or glycolic acid monomers) and a filler such as calcium carbonate (e.g., about 30-40% CaCO3 by weight (i.e., by weight of the composition as a whole)).

摘要： An implant drill guide (12, 72) and tower (18, 78) with one or more indicators (20, 80) that may be aligned with the holes (8, 68) in the implant (6, 66) under fluoroscopy or other x-ray technique and may indicate the extents or boundaries of the securing member shaft or body. Certain embodiments involve methods of using a surgical system (2, 62) to predict or otherwise determine the placement and selection of a surgical securing member (10) . Certain embodiments involve the use of radiolucent indicators (20, 80) to allow more precise placement and selection of a surgical securing member (10) .

摘要： Systems, methods and processes for computer-assisted soft tissue balancing, including ligament balancing, determining surgical cuts, and positioning or placement of the components of the prosthetic knee during TKR. The improved methods, systems, and processes consider and correlate anatomical landmarks and dynamic interactions of the knee bones and soft tissues. The improved methods, systems and processes resolve several problems related to the prosthetic knee component positioning and soft-tissue balancing during computer-assisted TKR. The improved methods, systems and processes are flexible and versatile, provide reliable recommendations to the surgeon, and improve restoration of the knee function and patient recovery. The computer stores in its memory a logic matrix for assessing kinematics of the knee, and provides output in the form of recommendations on soft tissue balancing.
