摘要： Methods and apparatus facilitate the positioning of a prosthetic element relative to a bone so as to achieve a desired orientation. An anchoring unit rigidly attaches to a point of the bone surrounding a region associated with receiving the prosthetic element, and at least one structural member is used to physically couple the prosthetic element to the anchoring unit. The combination of the anchoring unit and structural member includes one or more fasteners which may be loosened to temporarily remove the prosthetic element once a desired orientation is achieved, while facilitating re-installation of the element in accordance with the desired orientation following the temporary removal. In a preferred embodiment, the prosthetic element is an acetabular implant, and the surrounding bone forms part of a human pelvis. Regardless of the application, the element may take the form of a trial or a final implant.

摘要： Apparatus and method are disclosed for maintaining the proper positioning of an implant (310, 504) within a prepared bone cavity (312) during cement injection and curing. First stabilization means (340, 480), implantable within the bone cavity, minimize lateral movement of the implant distal end, while second stabilization means (330, 334, 406, 404), physically separate from the first stabilization means (340, 480), minimize both the lateral movement of the implant proximal end and the rotational movement of the implant overall. In the preferred embodiment, the second stabilization means (330, 334) includes an aperture cap (334) removable securable to the end of a prepared bone. This cap (334), preferably further includes first and second ports (322, 336) associated, respectively, with cement injection and cement over-pressurization. In an alterative embodiment, the second stabilization means (406, 404) includes a manually operated mechanism enabling (404) the implant (504) to be temporarily, yet rigidly, secured thereto in accordance with a desired orientation, preferably affording adjustments along multiple degrees of freedom prior to the rigid securement thereof.

摘要： Improved bone cutting guides enable a surgeon to better gauge required resection characteristics. In one embodiment at least a portion of the guide is transparent, thereby enabling the user to optimize cut estimates and to visualize the resection as it is being performed. In another embodiment, at least a portion of the outer surface of the body is shaped to interact with another bone or prosthetic element associated with a joint, thereby enabling the device to function both as a trial and as a cutting guide. In this embodiment as well the guide may be at least partially transparent to improve visualization. Although primarily intended for use in femoral-side knee arthroplasty, the invention is applicable to any procedure which might benefit from improved bone-cutting accuracy.
摘要翻译：改进的骨切割导轨使外科医生更好地测量所需的切除特征。在一个实施例中，引导件的至少一部分是透明的，从而使得使用者能够优化切割估计，并且在正在执行切割时可视化切除。在另一个实施例中，本体的外表面的至少一部分成形为与与关节相关联的另一骨或假体元件相互作用，从而使得该装置能够同时用作试验和切割引导。在该实施例中，引导件可以至少部分透明以改善可视化。虽然主要用于股骨侧膝关节置换术，但本发明适用于可能从改进的骨切割精度中获益的任何手术。

摘要： Modular acetabular reconstruction apparatus includes a generally cup-shaped portion adapted for fixation within a human pelvis and one or malleable extension arms adjustable in multiple dimensions. Each arm preferably includes one or more apertured sections spaced apart from one another by a necked-down section enabling each arm to be manipulated in three dimensions for intimate physical conformity with surrounding bone. The back surface of the generally cup-shaped portion may be adapted for a cemented or a non-cemented interface within a human pelvis; as such, the back surface may be adapted for porous bone in-growth. According to a disclosed method, the step of bending each arm in multiple dimensions may be carried out a part of a trial joint reduction. Various bending tools and techniques are also set forth.

摘要： A proximal femoral prosthesis minimizes impingement, thereby affording an enhanced range of motion as compared to existing devices. The central portion of the neck of a prosthesis according to the invention is oriented distally relative to a straight line drawn between the ball portion and a point of interconnection to the exposed portion of the stem. Such a configuration reduces impingement in flexion/internal rotation and extension/external rotation, assuming an appropriately placed acetabular component. In the preferred embodiment, the neck is curved between the head and the neck. In alternative embodiments, the neck may be provided in straight and/or modular segments. The invention is compatible with neck-shaft angles, offsets, head sizes, and other dimensions commonly designated with respect to available implants.

摘要： A modified joint prosthesis component is provided to reduce the backside wear of the joint implant. Whether the joint implant is for the knee joint, the hip joint or another joint, it is the modified bearing insert engaging surface of the metal base construct that provides for greater friction and therefore less micro-motion and resultant minimized backside wear.

摘要： A hospital type of bandage integrates an absorbent pad and non-stick layer with a fluid-impermeable outer layer and an adhesive in a single composite structure. In a preferred embodiment the invention further includes means which may be used to turn the bandage inside out upon removal, so that surfaces once contacting a patient are no longer externally exposed. A bandage according to the invertible embodiment preferably includes a pocket formed on the side of the bandage facing away from the patient after application, this pocket being large enough to accommodate at least a portion of a human hand, and inside this pocket and located opposite the entrance is a means for grasping which may be pulled outwardly through pocket opening, thereby inverting the entire structure. Various forms of devices for grasping are possible as alternatives, including a string, a tab and a tab with one or more finger-receiving holes. Means are further included for sealing the inverted structure, preferably in the form of a flap and associated adhesive.
