    JOSEPH, J. R., SMITH, B. W., PATEL, R. D., <(>&<)>AMP; PARK, P. (2016). USE OF 3D CT-BASED NAVIGATION IN MINIMALLY INVASIVE LATERAL LUMBAR INTERBODY FUSION. JOURNAL OF NEUROSURGERY: SPINE, 25(3), 339¿344. HTTPS://DOI.ORG/10.3171/2016.2.SPINE151295. SUMMARY: OBJECTIVE: LATERAL LUMBAR INTERBODY FUSION (LLIF) IS AN INCREASINGLY POPULAR TECHNIQUE USED TO TREAT DEGENERATIVE LUMBAR DISEASE. THE TECHNIQUE OF USING AN INTRAOPERATIVE CONE-BEAM CT (ICBCT) AND AN IMAGE-GUIDED NAVIGATION SYSTEM (IGNS) FOR LLIF CAGE PLACEMENT HAS BEEN PREVIOUSLY DESCRIBED. HOWEVER, OTHER THAN A SMALL FEASIBILITY STUDY, THERE HAS BEEN NO CLINICAL STUDY EVALUATING ITS ACCURACY OR SAFETY. THEREFORE, THE PURPOSE OF THIS STUDY WAS TO EVALUATE THE ACCURACY AND SAFETY OF IMAGE-GUIDED SPINAL NAVIGATION IN LLIF. METHODS: AN ANALYSIS OF A PROSPECTIVELY ACQUIRED DATABASE WAS PERFORMED. THIRTY-ONE CONSECUTIVE PATIENTS WERE IDENTIFIED. ACCURACY WAS INITIALLY DETERMINED BY COMPARISON OF THE PLANNED TRAJECTORY OF THE IGNS WITH POST¿CAGE PLACEMENT INTRAOPERATIVE FLUOROSCOPY. ACCURACY WAS SUBSEQUENTLY CONFIRMED BY POSTPROCEDURAL CT AND/OR RADIOGRAPHY. CAGE PLACEMENT WAS GRADED BASED ON A PREVIOUSLY DESCRIBED SYSTEM SEPARATING THE DISC SPACE INTO QUARTERS. RESULTS: THE MEAN PATIENT AGE WAS 63.9 YEARS. A TOTAL OF 66 SPINAL LEVELS WERE TREATED, WITH A MEAN OF 2.1 LEVELS (RANGE 1¿4) TREATED PER PATIENT. CAGE PLACEMENT WAS NOTED TO BE ACCURATE USING IGNS IN EACH CASE, AS CONFIRMED WITH INTRAOPERATIVE FLUOROSCOPY AND POSTOPERATIVE IMAGING. SIXTY-FOUR (97%) CAGES WERE PLACED WITHIN QUARTERS 1 TO 2 OR 2 TO 3, INDICATING PLACEMENT OF THE CAGE IN THE ANTERIOR OR MIDDLE PORTIONS OF THE DISC SPACE. THERE WERE NO INSTANCES OF MISGUIDANCE BY IGNS. THERE WAS 1 SIGNIFICANT APPROACH-RELATED COMPLICATION (PSOAS MUSCLE ABSCESS) THAT REQUIRED INTERVENTION, AND 8 PATIENTS WITH TRANSIENT, MILD THIGH PARESTHESIAS OR WEAKNESS. CONCLUSIONS: LLIF CAN BE SAFELY AND ACCURATELY PERFORMED UTILIZING ICBCT AND IGNS. ACCURACY IS ACCEPTABLE FOR MULTILEVEL PROCEDURES. REPORTED EVENT: THIRTY ONE PATIENTS WITH A HISTOLOGY OF DEGENERATIVE LUMBAR DISEASE UNDERWENT A LATERAL LUMBAR INTERBODY FUSION. ONE PATIENT DEVELOPED A PSOAS MUSCLE ABSCESS. TWO PATIENTS HAD A MYOCARDIAL INFARCTION, WITH ONE BEING A NON-ST-SEGMENT ELEVATION ASSOCIATED WITH ATRIAL FIBRILLATION AND RAPID VENTRICULAR RESPONSE. ONE PATIENT DEVELOPED THE MILLER-FISHER VARIANT OF ACUTE WITH INTERMITTENT DEMYELINATING POLYNEUROPATHY. ANOTHER PATIENT DEVELOPED URINARY RETENTION. ALL THE ABOVE PATIENTS MADE A FULL RECOVERY WITH NO RESIDUAL EFFECTS. ONE PATIENT'S PROCEDURE WAS ABORTED DUE TO AN ENDPLATE FRACTURE THAT OCCURRED DURING DISC PREPARATION. SEE ATTACHED ARTICLE.
