11 Lateral Interbody Cages

11.1 Introduction

Perhaps the most distinguishing characteristic of lateral interbody cages is the larger footprints they afford, in addition to accommodating multiple methods of supplemental fixation. ¹ ^, ² The rate of subsidence appears to be lower when wider cages are used, ¹ ^, ² as evidenced by lateral interbody cages demonstrating lower rates of subsidence than comparable posterior interbody cages. ¹
