Complication avoidance in the lateral approach for interbody fusion

The lateral approach to the spine for interbody fusion is a relatively new surgical technique with different rates and types of complications that are not well defined. The goal of this chapter is to facilitate understanding, recognition, and prevention of complications associated with this approach. In general, postoperative motor deficits range in frequency from 0.7% to 7.1%. Thigh dysesthsias are common but typically transient. It is tolerated by elderly and obese patient populations. It can be used in osteoporotic patients but supplemental pedicle screw fixation may be recommended. Overall, the complication profile appears favorable, but efforts continue to reduce their incidence.
