Fracturas basicervicales tratadas con clavo intramedular con tornillo cefálico único. Serie de casos y revisión bibliográfica / Basicervical fractures treated with single-screw cephalomedullary nail. Case series and review of the literature

Introducción: Debido a la inestabilidad rotatoria de las fracturas basicervicales, en estudios recientes, se sugiere el uso de una hoja espiral, doble tornillo o tornillos de compresión en lugar del tornillo cefálico único. Objetivo: Analizar los resultados de las fracturas basicervicales tratadas con tornillo cefálico único en nuestro centro. Materiales y Métodos: Estudio retrospectivo de una serie de casos formada a partir de la revisión de todas las fracturas extracapsulares de fémur proximal tratadas con clavo intramedular con tornillo cefálico único entre 2016 y 2020. Se revisaron las historias clínicas y las radiografías de 269 pacientes, y solo 12 (6,4%) de ellos cumplieron los criterios de inclusión (fracturas en dos fragmentos no patológicas y con seguimiento mínimo de 9 meses). Se evaluaron diferentes factores, como distancia punta-ápex, posición del tornillo cefálico, calidad de la reducción, tiempo quirúrgico, complicaciones y reintervención, y se analizaron las posibles diferencias entre los pacientes que sufrieron complicaciones y los que no. Resultados: Cuatro de los 12 pacientes tuvieron una falla de la fijación que evolucionó a cut-out (única complicación identificada en la muestra). No hubo diferencias estadísticamente significativas entre pacientes con cut-outo sin cut-out respecto al resto de las variables analizadas. Conclusiones: La elevada proporción de pacientes que desarrollaroncut-out sugiere considerar la hipótesis de que debería evitarse fijar las fracturas basicervicales con tornillo cefálico único. Dada su alta tasa de inestabilidad rotatoria, podría ser más apropiado el uso de implantes que la contrarresten. Nivel de Evidencia: IV

Background: Given the rotational instability of basicervical fractures, recent studies suggest using a spiral blade, a second screw or compression screws instead of single-screw cephalomedullary nail fixation. Objective: The aim of our study is to analyze the outcomes of basicervical fractures treated with single-screw cephalomedullary nails. Materials and Methods: This is a retrospective study based on a case series identified from all extracapsular femoral fractures treated with single-screw cephalomedullary nails in our hospital from 2016 to 2020. Clinical records and radiographs from 269 patients were reviewed; only 12 (6.4%) subjects met inclusion criteria (two-part non-pathologic fractures with at least a 9-month follow-up). Different factors were evaluated, including: tip-apex distance, cephalic screw position, reduction quality, surgical time, complications and re-operations; differences between patients who experienced complications and those who did not were also assessed. Results: Four subjects out of the 12 included patients experienced fixation failure and implant cut-out. There were no statistically significant differences between subjects with and without cut-out regarding the analyzed variables. Conclusions: The high cut-out rate observed in our sample suggests considering the hypothesis that single-screw cephalomedullary nail fixation should not be used in basicervical fractures. Alternative fixation devices capable of controlling the high rotational instability of these fractures may be preferable. Level of Evidence: IV

Desenvolvimento de competências de prática baseada em evidência dos enfermeiros: contributos da supervisão clínica / Development of nurses' evidence-based practice skills: contributions of clinical supervision

RESUMO Objetivo avaliar o impacto da implementação do Modelo SafeCare nas competências de prática baseada em evidência dos enfermeiros. Métodos método misto caracterizado pela triangulação concomitante. Os dados quantitativos foram coletados antes e após a implementação do Modelo, por meio do Questionário de Eficácia Clínica e Prática Baseada em Evidências, com análise estatística descritiva. Os valores de prova foram obtidos com recurso ao teste de Wilcoxon. Participaram 13 enfermeiros. Os dados qualitativos foram obtidos de entrevistas com 11 enfermeiros de um hospital público e analisados pela técnica de Análise de Conteúdo. Resultados não houve diferenças estatisticamente significativas com a implementação do modelo. Contudo, os enfermeiros identificaram o aumento de competências em prática baseada em evidência com o reconhecimento de vantagens no seu desenvolvimento profissional, na organização e na assistência ao paciente. Conclusão a implementação do modelo mostrou ter contribuído para o desenvolvimento das competências em prática baseada em evidência.

ABSTRACT Objective to evaluate the impact of the implementation of the SafeCare Model on the evidence-based practice competencies of nurses. Methods mixed method characterized by concomitant triangulation. Quantitative data were collected before and after the implementation of the Model, by means of the Clinical Effectiveness and Evidence-Based Practice Questionnaire, with descriptive statistical analysis. Evidence values were obtained using the Wilcoxon test. Thirteen nurses participated. Qualitative data were obtained from interviews with 11 nurses from a public hospital and analyzed using the Content Analysis technique. Results there were no statistically significant differences with the implementation of the model. However, nurses identified increased competencies in evidence-based practice with the recognition of advantages in their professional development, organization, and patient care. Conclusion the implementation of the model has been shown to have contributed to the development of competencies in evidence-based practice.
