RESUMO
BACKGROUND: This study evaluates the efficacy of the calcaneo-stop (C-Stop) procedure's effectiveness in treating symptomatic flexible flatfoot (FFF) in children. METHODS: A systematic review and meta-analysis were conducted using PubMed, Embase, and Cochrane databases to identify studies until 2023 on the outcomes of the C-Stop procedure in children with FFF. The risk of bias was assessed using MINORS criteria. RESULTS: Of 85 studies screened, 20 involving 2394 feet from 1415 patients (mean age 11.2 ± 1.3 years) were included. Post-procedure, significant improvements were noted in pain reduction (93.5%), heel alignment (95.21%), and radiological measures, including reductions in Kite (7.32º), Meary (11.65º), Costa-Bartani angles (17.11º), talar declination (12.63º) and increase in Calcaneal Pitch Angle (5.92º). AOFAS scores increased by 22.32 points on average, with 94.83% reporting high satisfaction. Complication rate was low (7.8%). CONCLUSIONS: The C-Stop procedure is effective for treating FFF in children, offering significant clinical, radiological, and functional improvements with high patient satisfaction and a low complication rate. LEVEL OF EVIDENCE: Level IV, Systematic review of Level-IV studies.
RESUMO
INTRODUCCIÓN: El Gross Motor Function Classification System ha permitido estratificar, según su habilidad para caminar, a los pacientes que padecen parálisis cerebral infantil. La falta de sensibilidad en la detección de cambios y la ausencia de una evaluación del paciente en el contexto en el que se encuentra justifican la búsqueda de alternativas de evaluación pretratamiento. OBJETIVOS. Presentar y mostrar la concordancia interobservador inicial del sistema de clasificación de niveles de deambulación funcional. Con él se evalúa la destreza para caminar y la necesidad de asistencia para realizar transferencias desde la silla de ruedas, y, posteriormente se analiza el escenario que la salud y el entorno del paciente ofrecen como condicionantes en la corrección de la marcha o la bipedestación asistida. SUJETOS Y MÉTODOS: Se describe un nuevo marco de evaluación, elaborado por un grupo interdisciplinar con más de 15 años de experiencia media, enfocado inicialmente a la toma de decisiones antes de un tratamiento quirúrgico. Como control interno, 14 participantes evaluaron la historia clínica y los vídeos de marcha de 10 casos. RESULTADOS: Se alcanzó un índice kappa de acuerdo de 0,76 en niveles funcionales y de 0,79 en el tipo de escenario biológico, de 0,69 en el psicológico y de 0,64 en el social. CONCLUSIONES: El sistema de clasificación de niveles de deambulación funcional ofrece un marco para la evaluación conjunta de la deambulación y de los factores limitantes en la eficacia de un tratamiento. La concordancia interobservador avala iniciar su validación
INTRODUCTION: The Gross Motor Function Classification System has allowed us to stratificate cerebral palsy patients, according to their walking abilities. The lack of sensitivity about detecting changes and the absence of a global patient evaluation, justify the search of new pre-operative evaluation tools. AIMS. To present the Walking Abilities Levels Classification System (WALCS) and to show the first inter-observer agreement study that has been carried out. This system uses first a different pattern for ordering gait functional skills, and after that, evaluates the reversibility of the contextual factors that may limit the result of a gait disorder treatment. SUBJECTS AND METHODS: A new evaluation frame was built by an interdisciplinary team with an average professional experience of more than 15 years, initially focused as part of the pre-surgical patient evaluation. An inter-observer agreement study was held to gain the first insight of it. 14 participants studied the medical reports and gait lab video images of 10 cases. RESULTS: The kappa index was 0.76 for the walking ability level, 0.79 for the biological type, 0.69 psychological type and 0.64 social type of limiting factors. CONCLUSIONS: The WALCS offers a new evaluation frame gathering patient walking skills and limiting factors treatment. The initial inter-observer agreement rate endorsed more intra- and inter-studies in order to achieve a more robust validation
