[S2 Alar-Iliac Screws in Fixation and Correction of Combined Neuromuscular Spinal and Pelvic Deformities].

PURPOSE OF THE STUDY Neuromuscular deformities of the spine represent surgically uneasy to solve problems as well as serious handicaps causing sitting instability, pressure ulcers as well as pain. The aim of our study is to conduct a retrospective clinical analysis of the results of surgical correction of these deformities. This paper presents the use of a recent technique of sacral-alar-iliac (S2AI) screws and its comparison with other techniques of pelvic stabilisation.

[Comparison of two surgical methods for treatment of idiopathic thoracic scoliosis - anterior versus posterior approaches].

Purpose Of The Study: The aim of this retrospective randomised study is a comparison of two surgical approaches (anterior versus posterior) for the treatment of idiopathic thoracic scoliosis by corrective spondylodesis with segmental instrumentation in adolescents aged 13 to 20 years.

Material And Methods: The study included patients with right-sided idiopathic thoracic scoliosis (Cobb's angle, 40°-70°; Lenke type I). The group of patients treated from the posterior approach by fusion and segmental instrumentation, involving the use of a hybrid, tworod system or screws only, comprised 31 girls with an average age of 14.

[Infections in surgery of idiopathic scoliosis].

Purpose Of The Study: In this retrospective study, we evaluated infectious complications in the patients undergoing surgical treatment for idiopathic scolions in order to identify risk factors for postoperative infections.

Material: A total of 786 patients with idiopathic scoliosis were operated on during 24 years. In 754 (96%) cases, we used the posterior approach, involving posterior fusion and internal fixation, and subsequent immobilization in a brace.
