Objectives: To compare the surgical treatment of neuromuscular scoliosis (NMS) with and without intraoperative skull-skeletal traction (ISST) in terms of the degree of curve correction, surgical time, hospitalization time, screw density, use of blood products,and complications. Methods: A comparative retrospective study, in which we analyzed the medical records and radiographs of 17 patients who underwent surgical treatment for neuromuscular scoliosis (NMS). They were divided into two groups, with 9 and 8 patients operated with and without ISST, respectively, at a referral hospital specialized in the treatment of spinal deformitiesfrom 2019 to 2021. The categorical variables were analyzed using the Chi-squared test. Results: Among the 17 patients included in the study, there was a higher prevalence of women in the group without ISST (6 and 2) and of men in group with ISST (5 and 3). The ages of the patients in the two groups ranged from 8-19 years and from 11-29 years, respectively. The screw density used in the traction group averaged 66.33%±8.49 and 82.63%±17.25 in the non-traction group, a statistically significant differencewith a P-value of 0.036. The average percent correction was 76.81%±15.61 in the traction group as compared to an average of 66.39%±12.99 in the non-traction group. In addition, there were complications in 1 patient in each of the groups. Conclusions: Surgical treatment for NMS with ISST allows surgery using fewer blood products to maintain the same hematimetric level in the postoperative period. ISST also allows the use of a lower screw density to correct more severe deformities. Level of evidence III; Comparative retrospective study.
