Spinal arthroplasty device compatible with neural integrity monitoring
First Claim
1. An arthroplasty implant, comprising:
- a first member having an upper surface, a longitudinal side surface, and a lower surface;
a first electrode positioned on an outside portion of said longitudinal side surface of said first member oriented in an insertion direction of said arthroplasty implant; and
a connection terminal housed within said first member and electrically connected with said first electrode.

Abstract
A prosthetic implant is disclosed that includes at least one electrode mounted on an outside surface of the prosthetic implant and a connection terminal electrically connected with the electrode. A surgical instrument having a gripping member is used to selectively grip the prosthetic implant. The gripping member includes at least one connector oriented to be connected with the connection terminal of the prosthetic implant when the gripping member is secured to the prosthetic implant. An electrical stimulation signal generator is connected with the surgical instrument for providing electrical stimulation signals to the electrodes of the prosthetic implant thereby allowing a surgeon to neurologically monitor the implantation procedure.

20. A surgical method for inserting an implant, comprising:
-
creating a window to a bone structure; removing at least a portion of said bone structure; providing a prosthetic implant having at least one electrode positioned on an outside surface of said prosthetic implant, wherein said electrode is connected with at least one connection terminal positioned in said prosthetic implant; gripping said prosthetic implant with a surgical instrument such that a connector of said surgical instrument is electrically connected with said connection terminal of said prosthetic implant; inserting said implant through said window to replace said portion of said bone structure that has been removed using said surgical instrument; and generating an electrical stimulation signal that is selectively provided to said electrode while said prosthetic implant is being positioned to replace said portion of said bone structure. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)
