Кривая обучения при использовании малоинвазивной хирургической методики коррекции идиопатического сколиоза.

Abstract

The incidence of scoliosis remains stable. The only method of correcting scoliosis with an angle of curvature of the spine of more than 45° is surgical treatment. The most modern technique is the minimally invasive technique (MM). The purpose of the study: MM correction of scoliosis is a relatively new high-tech technique, which should take some time to master. This study aimed to analyze the learning curve when performing minimally invasive surgery.Methods. The analysis of MM data of 58 patients with idiopathic scoliosis and an average level of the curve of curvature of 51.7 ± 1.5 o was carried out; for 5 years, to build a learning curve, the time of the operation, correction of the main curve were estimated every year, the volume of blood loss was estimated for 5 years, with This took into account the number of operations to reach a plateau.Results. The operation time significantly decreased in the first 4 years or up to 52 patients from 413.6±25.8 min to 293.2±11.3 min, p<0.0001. The angle of correction in % increased up to 3 years, or 38 patients, from 17.9±2.6% to 25.8±2.4%, followed by a statistically insignificant increase over 2 years to 32±5.8% p =0.0051. The volume of blood loss decreased insignificantly over 5 years from 278.6±58.6 ml to 172.1±24.2 ml.Conclusions. Long-term surgical experience has been associated with reduced operative time, and improved scoliosis correction outcomes.Keywords. Minimally invasive surgery, scoliosis, learning curve
