    Abstract: A method for locating a tool for industrial operations that is positioned in a sequence of operating points of an operating sequence associated to different positions on a component on which work is to be carried out, includes associating a light source to the tool and at least three light sources identifying a position reference triplet fixed with respect to the component. A stereovision apparatus having at least two video cameras acquires at least two respective images of the tool and component. The displacement of the operating points on the component is tracked when carrying out an industrial operation on the component by recognizing positions of the reference triplet and a point of the light source of the tool calculating the position of the operating points of an operating sequence with reference to the position assumed by the reference triplet and evaluating the position of the tool with respect to the calculated position of the operating points.

Also from the obtained image data, a superior surface of the guides and implants can be shaped to match the acetabulum of the patient. A nub portion extending outwardly from the superior surface of the guides and implants is shaped to substantially match the shape of a fovea of the acetabulum. A guide portion of the guides forming a slot has a longitudinal axis coaxial with the determined insertional vector of a corresponding acetabular component.

A buttress member of an acetabular augment is placed at a selected angular position relative to an affixation member of the acetabular augment, as determined by a trialing procedure in which a trial buttress member is placed at the deficiency while a trial affixation member is placed upon natural bone at the implant site to determine a trial relative angular position between the trial buttress member and the trial affixation member of a trial acetabular augment located at the implant site. The relative angular position between the buttress member and the affixation member then is selected to mimic the trial relative angular position.

  • Patent number: 8696757
    Abstract: A prosthetic device for replacement of a first pelvic portion of a pelvis of a patient opposite to a second pelvic portion relative to a median plane includes an acetabular component a flange component and a pubis component. The acetabular component has a first connecting portion and a second connecting portion at an angle relative to the first connecting portion, the angle selected for a corresponding anatomy of the patient. The flange component is coupled to the first connecting portion and configured to attach to a healthy pelvic portion on a same side of the median plane from the first pelvic portion. The pubis component is connected to the second connecting portion of the acetabular component and having a clamping portion configured to attach to a healthy pubis bone on an opposite side of the median plane from the first pelvic portion.

  • Patent number: 8680173
    Abstract: A method of producing an improved polyethylene, especially an ultra-high molecular weight polyethylene utilizes a sequential irradiation and annealing process to form a highly cross-linked polyethylene material. The use of sequential irradiation followed by sequential annealing after each irradiation allows each dose of irradiation in the series of doses to be relatively low while achieving a total dose which is sufficiently high to cross-link the material. The process may either be applied to a preformed material such as a rod or bar or sheet made from polyethylene resin or may be applied to a finished polyethylene part.

  • Patent number: 8652212
    Abstract: An orthopedic component having multiple layers that are selected to provide an overall modulus that is substantially lower than the modulus of known orthopedic components to more closely approximate the modulus of the bone into which the orthopedic component is implanted. In one exemplary embodiment, the orthopedic component is an acetabular shell. For example, the acetabular shell may include an outer layer configured for securement to the natural acetabulum of a patient and an inner layer configured to receive an acetabular liner. The head of a femoral prosthesis articulates against the acetabular liner to replicate the function of a natural hip joint. Alternatively, the inner layer of the acetabular shell may act as an integral acetabular liner against which the head of the femoral prosthesis articulates.

  • Patent number: RE44803
    Abstract: 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.
