Abstract

Intervertebral implants and methods of delivering the intervertebral implants include delivering an implant through the Kambin's triangle from a posterolateral approach. The intervertebral implants can include a first body portion having an open configuration and a closed configuration. The intervertebral implants can also include a second body portion having an open configuration and a closed configuration. The first body portion removably connects to the second body portion.

What is claimed is: 
     
         1 . An intervertebral implant comprising:
 a first body portion comprising a first member, a second member, and a first joint portion;   a first shaft, the first member and the second member pivotable around the shaft;   a second body portion comprising a first member, a second member, and a second joint portion; and   a second shaft, the first member of the second body portion and the second member of the second body portion pivotable around the shaft,   wherein the first joint portion removably connects to the second joint portion.   
     
     
         2 . The implant of  claim 1 , wherein the first and second body portions include one or more apertures. 
     
     
         3 . The implant of  claim 1 , wherein the first and second body portions include one or more textured surfaces. 
     
     
         4 . The implant of  claim 3 , wherein the one or more textured surfaces includes a ribbed surface. 
     
     
         5 . The implant of  claim 1 , wherein the first and second body portions include a bioactive coating. 
     
     
         6 . The implant of  claim 1 , wherein the first joint portion and the second joint portion form a ball and socket joint. 
     
     
         7 . The implant of  claim 1 , wherein the first and second body portions include one or more depressions configured for interaction with a deployment tool. 
     
     
         8 . An intervertebral implant comprising:
 a body portion including a first member and a second member, the first body portion including an open configuration and a closed configuration;   a shaft, the first member of the first body portion and the second member pivotable around the shaft from the closed configuration to the open configuration,   wherein the body portion includes a motion limiting portion to limit rotational movement of first member relative to the second member when the body portion is in the open configuration.   
     
     
         9 . The implant of  claim 8 , wherein the first member is configured to translate along a central axis of the shaft. 
     
     
         10 . The implant of  claim 8 , wherein one or more surfaces of the body portion include a textured surface. 
     
     
         11 . The implant of  claim 10 , wherein the textured surface is a ribbed surface. 
     
     
         12 . The implant of  claim 8 , further comprising one or more apertures. 
     
     
         13 . The implant of  claim 8 , further comprising a bioactive coating. 
     
     
         14 . The implant of  claim 8 , wherein the body portion includes one or more depressions configured for interaction with a deployment tool. 
     
     
         15 . The implant of  claim 8 , wherein the body portion includes a spring-loaded mechanism capable of transitioning the body portion from the closed configuration to the open configuration. 
     
     
         16 . A method of performing orthopedic surgery comprising:
 engaging a first body portion with a deployment tool;   delivering the first body portion into an intervertebral space; and   transitioning the first body portion from a closed configuration to an open configuration.   
     
     
         17 . The method of  claim 16 , wherein delivering the first body portion further comprises delivering the first body portion through a posterolateral approach. 
     
     
         18 . The method of  claim 17 , wherein delivering the first body portion through the posterolateral approach further comprises delivering the first body portion through a Kambin's triangle. 
     
     
         19 . The method of  claim 14 , further comprising:
 engaging a second body portion with the deployment tool;   delivering the second body portion into the intervertebral space;   and transitioning the second body portion from a closed configuration to an open configuration.   
     
     
         20 . The method of  claim 19 , further comprising connecting a first joint portion of the first body portion to a second joint portion of the second body portion.
