Prosthetic device

A prosthetic device for replacing at least one vertebral body, the prosthetic device being expandable from a fully collapsed state to a fully expanded state and having

• an anterior end and a posterior end which are located on opposite sides of a vertical frontal plane;
• a proximal end and a distal end which are located on opposite sides of a vertical midsagittal plane arranged perpendicular to the frontal plane;
• and
• a top end and a bottom end which are located superiorly and inferiorly of a horizontal transverse plane, respectively,
• wherein the prosthetic device further comprises
• an upper endplate having a top surface that is located at the top end and is configured to abut against a first vertebral body,
• a lower endplate having a bottom surface that is located at the bottom end and is configured to abut against a second vertebral body,
• an expandable support structure extending between the upper and lower endplates, said expandable support structure being configured to displace the two endplates relative to one another along a longitudinal axis of the prosthetic device and to hold the two endplates at an axial distance that is measured between the top surface of the upper endplate and the bottom surface of the lower endplate and corresponds to the height of at least half a vertebral body and one intervertebral disc, and
• at least one fixation plate which extends from an edge of one of the endplates and approximately perpendicular thereto in a direction away from the other endplate, the fixation plate comprising at least one through-hole for receiving a fixation member therethrough,
• wherein the expandable support structure includes an anterior post and a posterior post, each post having an upper end hingedly connected to the upper endplate and a lower end hingedly connected to the lower endplate and each post having a length which is defined by the axial distance between the upper end and the lower end of the respective post, and
• wherein the length of each post is individually adjustable and is lockable independently from one another to hold the two endplates with an inclination of 0° to 40° relative to each other.

• wherein at least one of the endplates comprises a window or a grid-like structure for allowing the ingrowth of bone cells.
