Scheuermann’s disease surgery. Major problems: non-systematic literature review (part I).

Objective. To perform multivariate comparison of two surgical strategies in the treatment of patients with severe Scheuermann’s disease. Material and Methods. The search of sources (in Scopus and Web of Science databases) revealed  56 publications containing the required information. The literature data were analyzed in four directions: the results of one- and two-stage interventions are compared in terms of the magnitude of achieved correction and its preservation, the complication rate, the surgery duration and the volume of intraoperative blood loss, and the quality of life of patients in the postoperative period. Results. The magnitude of the achieved correction of kyphotic deformity and postoperative loss of correction in patients after one- and two-stage operations are almost identical. Implant-associated complications are more often observed after one-stage operations, and purulent, neurological and other complications – after two-stage operations. Surgery duration and intraoperative blood loss volume are greater in two-stage operations. The quality of life assessed by various questionnaires is significantly improved, regardless of the type of surgery. Conclusion. Two-stage surgical correction of Scheuermann’s kyphosis has no noticeable advantages over one-stage surgery, however, new studies with long (more than 15–18 years) postoperative follow-up are needed.
