Abstract (English): Introduction: Angular deformities around the knee, i.e., genu varum and genu valgum, are common in children and can arise from various underlying conditions. Surgical treatment options include temporary hemiepiphysiodesis (guided growth), which is less invasive and carries fewer risks compared to traditional osteotomies. While effective for coronal deformities, the impact of this technique on persistent torsional deformities remains underexplored. Objectives: This study aims to assess the persistent torsional deformity following complete correction of varus coronal deformity in pediatric patients treated with 8-plate hemiepiphysiodesis. Methods: A retrospective case series study was conducted in a tertiary center from March 2023 to January 2025. The study included skeletally immature patients aged 2.5 to 12 years with genu varum deformity who underwent 8-plate hemi-epiphysiodesis for varus deformity correction. Clinical and radiological assessments-including foot progression angle, thigh-foot angle and heel bisector line- were used to evaluate rotational deformities after varus correction. Results: A total of 26 limbs of 14 patients with mean age 4.54 years were analyzed. The mean duration of epiphysiodesis was 10.46 months. Despite successful correction of coronal deformities, 61.5% of patients exhibited persistent intoeing. The persistent torsion was of tibial source which was manifested in the foot progression angle and the thigh-foot angle. Conclusion: While 8-plate is effective for coronal deformity correction in pediatric genu varum, a significant proportion of patients retain persistent torsional deformities. [ABSTRACT FROM AUTHOR]
Abstract (Spanish): Introducción: las deformidades angulares alrededor de la rodilla, es decir, el genu varo y el genu valgo, son comunes en niños y pueden deberse a diversas afecciones subyacentes. Las opciones de tratamiento quirúrgico incluyen la hemiepifisiodesis temporal (crecimiento guiado), que es menos invasiva y conlleva menos riesgos en comparación con las osteotomías tradicionales. Si bien es eficaz para las deformidades coronales, el impacto de esta técnica en las deformidades torsionales persistentes sigue siendo poco explorado. Objetivos: Este estudio tiene como objetivo evaluar la deformidad torsional persistente tras la corrección completa de la deformidad coronal en varo en pacientes pediátricos tratados con hemiepifisiodesis de 8 placas. Métodos: se realizó un estudio retrospectivo de series de casos en un centro terciario entre marzo de 2023 y enero de 2025. El estudio incluyó pacientes esqueléticamente inmaduros de entre 2,5 y 12 años con deformidad de genu varo, sometidos a hemiepifisiodesis de 8 placas para la corrección de la deformidad en varo. Se utilizaron evaluaciones clínicas y radiológicas, incluido el ángulo de progresión del pie, el ángulo muslo-pie y la línea bisectriz del talón, para evaluar las deformidades rotacionales después de la corrección en varo. Resultados: se evaluaron 26 extremidades de 14 pacientes con una edad media de 4,54 años. La duración media de la epifisiodesis fue de 10,46 meses. A pesar de la corrección exitosa de las deformidades coronales, el 61,5% de los pacientes presentó marcha convergente persistente. La torsión persistente fue de origen tibial, manifestándose en el ángulo de progresión del pie y en el ángulo muslo-pie. Conclusión: si bien la placa de 8 es eficaz para la corrección de la deformidad coronal en el genu varo pediátrico, una proporción significativa de pacientes conserva deformidades torsionales persistentes.
