Abstract

Purpose

Lateral access lumbar interbody fusion (LLIF) is a minimally invasive technique that has an increasing popularity. It offers unique advantages and circumvents risk of certain serious complications encountered in other conventional spinal approaches. This study provides a statistical analysis defining the lateral access learning curve in the Asian population.

Methods

This prospective study included 32 consecutive patients who underwent LLIF from April 2012 to August 2014. The surgeries were performed by two senior spine surgeons and follow-up was conducted at 6 weeks, 3, 6, 9 months and 1 year post-operation.

Results

The breakpoint in operating time occurred at the 22nd level operated, from a mean of 71 min in the early phase group to a mean of 42 min in the steady state group. LLIF at L4/5 level is technically more demanding but technically feasible as competency is achieved.

Conclusions

During the learning process, there was no compromise of perioperative or clinical outcomes. It should be feasibly incorporated into a spine surgeon’s repertoire of procedures for the lumbar spine.
