Abstract

A surgical instrument and method are provided for removal of a spinal implant from the intervertebral disc space. The instrument includes a carriage body for interfacing with the implant, a housing for interfacing with the vertebrae, and a handle portion having a first portion rotatably coupled with a proximal end of the housing and a second portion rotatably engageable with a proximal attachment portion of the carriage body. A central passage of the housing extends between the proximal end and a distal engagement surface of the housing. The central passage is dimensioned to mate with the carriage body. Rotation of the handle portion about an axis causes translational movement of the carriage body along the axis. A modular inserter/distractor apparatus and method and an anchor remover and method are also provided.

Claims16

Dependent claims

A method of inserting an implant in the intervertebral disc space between two adjacent vertebrae, the method comprising the steps of:

attaching a distal end of an engagement body to the implant, a proximal end of the engagement body connected with a handle portion such that the implant is disposed between superior and inferior distraction rails extending distally from the handle portion;
and
rotating the handle portion about an axis to cause translational movement of the engagement body along the axis to force distal ends of the rails apart from one another;
inserting the implant into the disc space by rotating the handle portion such that the implant passes distally between the rails and into the disc space;
and
inserting an anchor into engagement with the implant and an adjacent vertebra, including slidably translating the anchor toward the implant with a portion of the anchor disposed within a track embedded within a superior surface or an inferior surface of the engagement body.
