Revisable prosthetic device
First Claim
1. An anchoring device for disposition within an intervertebral space, comprising:
- first and second end members, the first and second end members cooperating to slidably receive a prosthetic insertion device,wherein the first and second end members each comprisea first surface, at least one vertebral-engaging member extending from the first surface,a second surface in an opposed relation to the first surface, a first sidewall, a second sidewall, and a back wall extending from the second surface to define a socket adapted to receive a portion of the prosthetic insertion device; and
at least one retention member having a first end and an engagement portion, the first end attached to a portion of the end member, the at least one retention member rotatable between a first position wherein the engagement portion is positioned outside of the socket for allowing the portion of the prosthetic insertion device to slide within the socket and a second position wherein the engagement portion is positioned at least partially within the socket to inhibit sliding of the portion of the prosthetic insertion device within the socket.

Abstract
A modular prosthetic device is described. The modular prosthetic device is provided with an anchoring device having first and second end members, the first and second end members cooperating to receive a prosthetic insertion device. The first and second end members each include a first surface, at least one vertebral-engaging member extending from the first surface, a second surface in an opposed relation to the first surface, and at least one flange extending from the second surface. The anchoring device is adapted to receive a variety of prosthetic insertion devices such that the modular prosthetic device can be revised into a variety of modular prosthetic devices. A stacking member is also provided for use with the anchoring device to provide a variety of modular, stackable prosthetic devices.

14. An anchoring device for receiving a prosthetic insertion device, comprising:
-
a first end member, comprising; a first surface in an opposed relation to a substantially parallel second surface; a pair of vertebral-engaging members extending from the first surface, the vertebral-engaging members being angled towards one another; a pair of flanges extending from the second surface, the flanges being angled towards one another to define a pair of elongated slots, the pair of elongated slots adapted to slidably receive a portion of the prosthetic insertion device; and a pair of retaining devices positioned adjacent the elongated slots, the retaining devices moveable between a first position for allowing the prosthetic insertion device to slide within the pair of elongated slots and a second position for limiting the motion of the prosthetic insertion device within the pair of elongated slots; a second end member cooperating with the first end member to slidably receive the prosthetic insertion device, the second end member comprising; a first surface in an opposed relation to a substantially parallel second surface; a pair of vertebral-engaging members extending from the first surface, the vertebral-engaging members being angled towards one another; a pair of flanges extending from the second surface, the flanges being angled towards one another to define a pair of elongated slots, the pair of elongated slots adapted to slidably receive a portion of the prosthetic insertion device; and a pair of retaining devices positioned adjacent the elongated slots, the retaining devices moveable between a first position for allowing the prosthetic insertion device to slide within the pair of elongated slots and a second position for limiting the motion of the prosthetic insertion device within the pair of elongated slots.

24. A system for securing a prosthetic insert within an intervertebral space, comprising:
-
a first end member comprising; a first surface, at least one vertebral-engaging member extending from the first surface, a second surface in an opposed relation to the first surface, a first sidewall, a second sidewall, and a back wall extending from the second surface to define a first socket adapted to receive a first portion of the prosthetic insertion device, at least one retention member having a first end and an engagement portion, the first end attached to a portion of the end member, the at least one retention member selectively rotatable between a first position wherein the engagement portion is positioned outside of the first socket for allowing the first portion of the prosthetic insert to slide within the first socket and a second position wherein the engagement portion is positioned at least partially within the first socket to inhibit sliding of the first portion of the prosthetic insert within the first socket, and a tool receiving aperture for accessing the at least one retention member; and a tool having a working end sized to fit at least partially within the tool receiving aperture of the end member, wherein the tool is adapted to selectively rotate the at least one retention member between the first position and the second position. - View Dependent Claims (25, 26, 27)
