摘要:
Surgical trays and tools for use in hip revision surgery wherein the implanted prosthesis is a reverse prosthesis comprising an acetabular ball and a femoral cup. A set of trays is provided having tools for i) separating a femoral cup from an acetabular ball, ii) separating a femoral cup from a femoral implant and iii) separating an acetabular ball from an acetabular cup. A tool for removing an acetabular cup from an acetabulum is also described. A surgical method is also provided wherein the acetabular ball and femoral cup are separated first followed by, in any order, separating the femoral cup from the femoral implant and separating the acetabular ball from the acetabular cup.
摘要:
Prosthetic intervertebral discs and methods for using the same are described. The subject prosthetic discs include upper and lower endplates separated by a compressible core member. The prosthetic discs described herein include one-piece, two-piece, three-piece, and four-piece structures. The subject prosthetic discs exhibit stiffness in the vertical direction, torsional stiffness, bending stiffness in the saggital plane, and bending stiffness in the front plane, where the degree of these features can be controlled independently by adjusting the components of the discs. The interface mechanism between the endplates and the core members of several embodiments of the described prosthetic discs enables a very easy surgical operation for implantation.

An implantable modular orthopaedic hip prosthesis includes an implantable distal stem component having a tapered post which can be received into a tapered bore of an implantable proximal body component. A threaded bore extends inferiorly into the distal stem component, and an alignment key is secured to the superior surface of the distal stem component and extends superiorly therefrom.

A device (10) for treating flat feet, comprising an expandable block (11) with an axial seat (12) for an expander insert (13) adapted to be inserted in the axial seat (12), the expandable block (11) comprising two opposite end parts (14, 15) and a central part (16), the two opposite end parts (14, 15) being configured to be deformed so as to increase their own radial space occupation with respect to the central part (16) when the expander insert (13) is arranged in the axial seat (12).
摘要:
An intervertebral implant frame that is configured to be attached to a spacer body can include a pair of arms that extend longitudinally from a support member such that the arms extend substantially around the spacer body. The arms may be configured to expand, crimp, or otherwise engage the spacer body to thereby hold the spacer body to the frame. The spacer body may be made from bone graft.
