    摘要： A modular intramedullary nail includes three connectable sections that are connectable end to end. The three sections include an upper proximal nail component, a lower distal nail component, and a central nail component. The nail components are connected and the end using corresponding frustroconical socket and frustroconical projecting end portions of adjoining end nail components that can be fitted together with a taper lock or morse taper connection and secured tightly together upon impact. Upon assembly, the connections are self orienting, providing corresponding key and slot portions adjacent the respective frustroconical socket and frustroconical projecting end portions of the nail components. The interlocking keys and slot align and abut upon assembly so that the adjoining nail components only align in one relative rotational position.

    摘要： A fixation device for fastening a medical implant to a patient'3 s bone is provided which includes a fastener with a head member and a shank and a fixation member. The shank has threads along its whole length, and has an outside diameter greater than the width of the head member. The fixation member includes a bore for receiving the fastener. The bore has a diameter intermediate the width of the head member and the outside diameter of the threads of the shank. The head member of the fastener can thus be inserted into the bore such that the uppermost thread abuts against the underside of the fixation member to prevent the fastener from backing out.

    摘要： Ossicular replacement prostheses are manufactured from a non-biodegradable shape memory polymer. Such prostheses can include TORPs, PORPs, and incudo-stapedial joints (ISJs). The prostheses are reshaped upon application of a stimulus to capture a portion of one or more ossicles. The force of capture of a reshaped polymeric prosthesis is less than a comparable reshaped shape memory alloy prosthesis and thereby prevents recipient discomfort and/or pressure induced necrosis of the bone. In addition, biocompatible shape memory polymers can be designed with recoverable strain that is orders of magnitude higher than shape memory alloys. Furthermore, prostheses can be manufactured in a single size and easily trimmed or otherwise modified by the surgeon during the implantation procedure to tailor the prosthesis in size and/or shape for the particular anatomy. Such modification does not negatively effect the ability of the prostheses to engage the ossicle.

    摘要： A mobile bearing knee prosthesis enables a surgeon to convert a mobile bearing insert having articular surfaces, supported by a tibial base plate or tray from a rotating and translating prosthesis to one that rotates only. This conversion is accomplished with a fastener or locking member that connects through an opening in the insert to the tibial base plate. This prosthesis can be used as part of a total knee surgery when the surgeon chooses to use a prosthesis that incorporates a movable articular surface. In one embodiment, a projecting portion extends proximally from the insert and cooperates with a cam on the femoral component. The projecting portion can be a post extending up from the proximal surface of the insert and the femoral component includes an intercondylar surface that may contact the post to constrain the relative motion between the femoral component and the insert. In another embodiment, the insert is a two part assembly that includes a larger member with a central opening and a smaller member that fits the opening.
