摘要： A modular hip prosthesis can be custom fitted to a particular patient by a surgeon prior to surgical insertion. The prosthesis features a body having a neck portion for carrying a rounded head element, a transitional mid-section of the prosthesis body includes generally rectangular and generally rounded cross-sectional areas, and a stem section has a generally rounded cross-sectional area. The stem is tapered to receive a tubular extension sleeve with a hollowed portion corresponding in shape to the stem portion of the prosthesis. The tubular extension sleeve has an open end portion receptive of the lower tapering stem of the prosthesis body. The stem portion includes an internal bore, and an attachment in the form of an elongated screw is provided for connection to the stem internal bore for securing the extension sleeve and the prosthesis body together, forming a compressive sealed connection therebetween. Pads can be attached to the transitional mid-section of the prosthesis body for increasing the cross-sectional shape of the prosthesis at the transitional mid-section. The pads are loaded continuously to connect to the prosthesis body by the hip joint reaction force. Removable collars can be added to the prosthesis to form a transverse load carrying interface with the upper end of the patient's femur. Frustro-conically shaped extension sleeves can be added to the prosthesis neck for extending the neck length.

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： The present invention provides for an artificial bone graft implant for use as a replacement for living bone material in surgical procedures requiring the use of bone graft material. The implant has a body configured to be implanted into a prepared site in a patient's bone tissue, with the body having a pair of opposed outer surfaces defining the body. A first and a second porous portion form the body with the first and second porous portions having pores of different sizes such that the average pore size of the first porous portion is greater than the average pore size of the second porous portion. The first porous portion of the body is formed in the shape of a core, with the core being in contact with the opposed outer surfaces of the body, and the second porous portion of the body is formed in the shape of an outer shell. The pore size of the first porous portion of the implant allows for the ingrowth of bone tissue and the pore size of the second portion of the implant allows for a load bearing capacity similar to natural bone.

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.
摘要翻译：移动轴承膝关节假体使得外科医生能够将具有由胫骨基板或托盘支撑的关节表面的移动轴承插入件从旋转和平移假体转换成仅旋转的假体。这种转换是通过将插入物中的开口连接到胫骨基板上的紧固件或锁定构件实现的。当外科医生选择使用包含可动关节表面的假体时，该假体可用作全膝关节手术的一部分。在一个实施例中，突出部分从插入件向近侧延伸并与股骨部件上的凸轮配合。突出部分可以是从插入件的近侧表面向上延伸的柱，并且股骨部件包括可以接触柱的髁间表面，以限制股骨部件和插入物之间的相对运动。在另一个实施例中，插入件是两部分组件，其包括具有中心开口的较大构件和适合开口的较小构件。
