ABSTRACT Objectives: Evaluate the efficacy and effects of releasing the muscles of subluxated hips of patients with SCZ. Methods: This is a retrospective study with 29 patients with subluxation of the hip, corresponding to 55 hips operated in a public hospital in Recife, Brazil. Preoperative femoral head migration (PM) percentages were evaluated and compared with 6- and 12-month postoperative results. Results: Twenty-nine patients were eligible, representing 55 hips evaluated. 19 were female (65.5%), with a mean age of 31.45 months (ranging from 23 to 42 years). 19 patients were GMFCS level V (65.5%), 34.5% were level IV, and 20 of the 29 patients (69%) had no complications. The PM had an absolute reduction of 11.6% (GMFCS IV) and 13.31% (GMFCS V) in the first six months. After 12 months, there was a regression of MP of 7.14% (GMFCS V) and 11.25% (GMFCS IV) compared to preoperative values, with no significant statistical difference among MP values presented between 6 and 12 months after surgery. Conclusions: The surgery was effective in PM regression during the analyzed period and presented a low complication rate. Level of Evidence III; Comparative retrospective study.

RESUMO Objetivos: Avaliar a eficácia e os efeitos da liberação das musculaturas de quadris subluxados de pacientes com SCZ. Métodos: Trata-se de um estudo do tipo retrospectivo com 29 pacientes CZS com subluxação do quadril, correspondendo a 55 quadris operados em um hospital público de Recife, Brasil. Foram avaliados os percentuais migratórios da cabeça femoral (PM) no pré-operatório e comparados com os resultados pós-operatórios de 6 e 12 meses. Resultados: Foram elegíveis 29 pacientes, representando 55 quadris avaliados. 19 eram do sexo feminino (65,5%), com média de idade de 31,45 meses (variando de 23 a 42 anos). 19 pacientes eram GMFCS nível V (65,5%), 34,5% eram nível IV e 20 dos 29 pacientes (69%) não apresentaram complicações. O PM teve redução absoluta de 11,6% (GMFCS IV) e de 13,31% (GMFCS V), nos primeiros seis meses. Após 12 meses, houve regressão do PM de 7,14% (GMFCS V) e de 11,25% (GMFCS IV) em relação aos valores pré-operatórios, sem diferença estatística entre os valores do PM apresentados entre 6 e 12 meses da cirurgia. Conclusões: A cirurgia foi eficaz em regredir o PM no período analisado e apresentou uma baixa taxa de complicações. Nível de Evidência III; Estudo retrospectivo comparativo.

ABSTRACT PURPOSE: Implement a constructivist approach in thoracic drainage training in surgical ex vivo pig models, to compare the acquisition of homogeneous surgical skills between medical students. METHODS: Experimental study, prospective, transversal, analytical, controlled, three steps. Selection, training, evaluation. Inclusion criteria: a) students without training in thoracic drainage; b) without exposure to constructivist methodology. 2) Exclusion criteria: a) students developed surgical skills; b) a history of allergy. (N = 312). Two groups participated in the study: A and B. Lecture equal for both groups. Differentiated teaching: group A, descriptive and informative method; group B, learning method based on problems. A surgical ex vivo pig model for training the chest drain was created. Were applied pre and post-test, test goal-discursive and OSATS scale. RESULTS: Theoretical averages: Group A = 9.5 ± 0.5; Group B = 8.8 ± 1.1 (p = 0.006). Medium Practices: Group A = 22.8 ± 1.8; Group B = 23.0 ± 2.8 (p <0.001). CONCLUSION: Through the constructivist methodology implemented in the thoracic drainage training in surgical ex vivo pig models, has proven the acquisition of surgical skills homogeneous compared among medical students.
