The Society for Minimally Invasive Spine Surgery awarded Neel Anand, MD, clinical professor of surgery and director of spine trauma at Cedars-Sinai Spine in Los Angeles, a the "Global Forum Best Paper Award."
Dr. Anand's paper was titled "Analysis of the 10 best and 10 worst functional outcomes of Circumferential Minimally Invasive Surgical correction of Adult Spinal Deformity."
The award was presented at the annual meeting in Las Vegas last week. The study examined outcomes for CMIS correction of adult spinal deformity. The single-center study included data from a prospective database for patients who underwent surgical correction at 10 or more levels. The researchers found:
1. The 10 best patients reported average preoperative ODI of 31.3 and postoperative ODI of 2.6. The average preoperative VAS was 5.7 and postoperative VAS was 0.5. The average preoperative Cobb angle was 30.3 and postoperative Cobb angle was 14.6. The average SVA was 64.8 preoperatively and 22.7 postoperatively.
2. The 10 worst patients reported preoperative ODI of 63.6 and postoperative ODI of 55.8. Average VAS was 7.4 preoperatively and 4.4 postoperatively. The preoperative Cobb angle was 23.7 on average; postoperative Cobb angle was 8.8. The average preoperative SVA was 59.5 and postoperative SVA was 39.5.
3. There were no cases of postoperative pseudoarthrosis among the 10 best patients; there were four cases among the 10 worst patients.
4. The best 10 patients had significantly lower postoperative ODI and VAS scores with less complications and lower postoperative pseudoarthrosis incidence than the 10 worst patients.
5. Nearly all — 90 percent — of the patients in the worst outcome group underwent surgery before 2011. Factors including age, sex, depression, diabetes, BMI, smoking and baseline deformity weren't statistically significant.
