Abstract: Modular neck components for hip implants having independent variables associated with physical characteristics of the implant, including leg length, offset, and anteversion. During surgery, the surgeon may be confronted with a need to change a preoperatively-chosen modular neck. For example, the surgeon may desire a change in at least one of the variables, e.g., leg length, offset, and/or anteversion. The present disclosure allows the surgeon to quickly and easily select a different modular neck based on an evaluation of one of the variables without requiring reevaluation of the other variables.

Abstract: A case for modular neck components for hip implants. The case may include indicators based on independent variables associated with physical characteristics of the implant, including leg length, offset, and anteversion. During surgery, the surgeon may be confronted with a need to change a preoperatively-chosen modular neck. For example, the surgeon may desire a change in at least one of the variables, e.g., leg length, offset, and/or anteversion. The case allows the surgeon to quickly and easily select a different modular neck based on an evaluation of one of the variables without requiring reevaluation of the other variables. A method described herein may include preoperative planning in which a template including a grid coordinate system is used, which advantageously provides an intuitive system for the surgeon both preoperatively and during surgery.

Abstract: A surgical instrument including an inserter having a body and a head. The head is dimensioned for receipt within a cavity formed by a final junction surface, for example a female tapered surface, of a prosthetic component. In one exemplary embodiment, a portion of the head has a scratch hardness that is less than the scratch hardness of the prosthetic component, i.e., is formed from a softer material. This allows for the cover of the head to be received within the cavity formed by the final junction surface of the prosthetic component without substantially scratching or damaging the final junction surface.

Abstract: The present invention relates to provisional prosthetic components for a medical device and the surgical methods for utilizing the same. In one embodiment, the provisional prosthetic component includes a first portion and a core. The first portion is capable of mating with another prosthetic component. The first portion of the provisional prosthetic component may have a scratch hardness which is less than the scratch hardness of the prosthetic component. This allows for the first portion to be placed in mating engagement with the prosthetic component without scratching or damaging the junction of the prosthetic component. Additionally, the core of the provisional prosthetic component may have a scratch hardness greater than the scratch hardness of the first portion of the provisional prosthetic component and/or a stiffness sufficient to minimize deflection of the provisional prosthetic component during trial reduction and range of motion testing.

Abstract: A hip stem centralizer is provided for positioning a proximal portion of a femoral hip stem component within an intramedullary canal of a femur. The centralizer includes a cavity and a side wall defining a lateral skirt. The cavity is removably engageable with the proximal portion of the hip stem component to position the lateral skirt between the lateral portion of the hip stem component and the lateral portion of the intramedullary canal.
