Given the lack of high-quality evidence to guide surgical technique selection in DS, appropriateness criteria and classification systems have been developed based on expert opinion. The DSIC System uses imaging and patient characteristics to predict stability. The purpose of this study was to evaluate the DSIC system as a guide for technique selection by determining if patients within each DSIC Type have different outcomes when treated with various surgical techniques.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;Patients undergoing surgery for symptomatic DS were prospectively enrolled at two centers. All patients were classified by DSIC Type and surgical technique. Due to small numbers in some subgroups, decompression alone and decompression with uninstrumented fusion were combined as uninstrumented group and decompression with instrumented and circumferential fusion were combined as instrumented group.

Surgical technique varied significantly across DSIC Type, with decompression alone performed most commonly in DSIC I and decompression and fusion performed more commonly in DSIC II and III.
