Results of using the Smith-Robinson approach for herniated and extruded cervical discs. Technical note.

Abstract

SE of the Smith-Robinson approach for anterior cervical fusion has been limited chiefly to the treatment of spondylosis, because it has been felt that the exposure was inadequate for removal of protruded or extruded fragments from within the spinal canal. By contrast, the Cloward approach, which employs a dowel cutter, allows a more generous exposure of the ventral aspect of the spinal canal. We believe the Smith-Robinson approach to be less hazardous and more physiological, and in 1968 reported the successful use of this technique in the removal of 13 soft cervical disc protrusions. 1 Since that time we have used this technique exclusively in all cases of cervical discogenic disease. This paper analyzes that experience.
