Anterior Cruciate Ligament Rupture in Skeletally Immature Patients.

In the past 20 years, sports injuries in pediatric and adolescent athletes have increased dramatically, with anterior cruciate ligament (ACL) injuries accounting for more than 25% of all knee injuries at this age. Diagnosis is based on detailed clinical history, physical examination, and imaging assessment, where magnetic resonance imaging plays a central role. The growing immature skeleton presents specific characteristics, which require unique methods for surgical reconstruction, ideally avoiding the physes or minimizing the risk of damaging them. Specific rehabilitation protocols are needed, and these patients face a higher risk of recurrent and contralateral ACL injury. Nonsurgical treatment or delayed reconstruction has been associated with persistent instability, activity modifications, worst functional outcomes, and increased risk of irreparable injuries to menisci and articular cartilage. Consequently, surgical stabilization is the preferred treatment for most patients, despite the eventual risk of angular deformities or limb-length discrepancies due to iatrogenic physeal injury. A variety of surgical techniques have been described, depending on the skeletal maturity and growth remaining. Targeted prevention programs play a key role in reducing the risk of ACL injury, are easy to implement, and require no additional equipment. High-quality evidence supports its use in all pediatric athletes.

Developmental dysplasia of the hip screening programme in Chile.

PURPOSE: Developmental dysplasia of the hip (DDH) encompasses a wide pathological spectrum, from mild acetabular dysplasia to complete congenital hip dislocation at birth. Screening policies have been implemented in an effort to effectively identify and treat patients with DDH. Since 2009 there has been a national DDH programme in Chile. The current study evaluates the results of the programme in patients born between 2010 and 2015. METHODS: Records of patients hospitalized from 1st January 2010 to 31st December 2019 were retrieved from national databases. Those born from 1st January 2010 to 31st December 2015 who underwent a procedure for DDH under general anaesthesia during their first five years of life were selected. Sex, first surgical procedure and age at first surgical procedure were analyzed. The incidence of DDH that required major surgical treatment was calculated. RESULTS: A total of 961 children born from 1st January 2010 to 31st December 2015 underwent a procedure for DDH during their first five years of life. The number of major procedures was significantly lower than the number of minor procedures (269 vs 692). The incidence of major procedures was 0.18 per 1000 live births. Girls underwent a higher number of procedures than boys (831 vs 130), whereas 39.2% of the boys and 26.2% of the girls had major procedures. The mean age at the time of the first procedure was 15.35 months (sd 10.09; range 0.03 to 55.92 months). CONCLUSION: The present study suggests that the Chilean National DDH Screening Program is an appropriate programme with substantial benefits with respect to public health. LEVEL OF EVIDENCE: II.

Fracturas múltiples de huesos largos en una escolar portadora de picnodisostosis: Reporte de caso / Multiple long bone fractures in a child with pycnodysostosis: A case report

Las fracturas en edad pediátrica son una entidad importante para considerar. Hay enfermedades en que los huesos del niño se fracturan ante traumatismos de menor energía. La picnodisostosis es un tipo inusual de displasia cráneo-metafisaria autosómica recesiva, cuya primera manifestación clínica suele ser una fractura en hueso patológico. Se presenta a una paciente, caucásica, de 9 años de edad, con diagnóstico de picnodisostosis, que ingresó al hospital por fractura del fémur derecho, por un mecanismo de baja energía. Los estudios radiográficos mostraron fracturas del fémur bilateral, fractura proximal de la tibia izquierda y consolidación viciosa en antecurvatum. Esta rara enfermedad se diagnostica a edades tempranas por talla baja, por fracturas repetidas o por traumas de baja energía. Las opciones terapéuticas son limitadas, y no se ha desarrollado una cura definitiva. Es importante, ante un paciente pediátrico con rasgos dismórficos faciales y fracturas en hueso patológico, sospechar displasias óseas, tales como la picnodisostosis y sus diagnósticos diferenciales.

Fractures are an important entity to consider in pediatric patients. There are certain diseases in which bones fracture with a minimal trauma. Pycnodysostosis is an autosomal recessive unusual type of cráneo metaphyseal dysplasia, that presents frequently as fracture in a pathological bone. A 9 year old caucasian female, diagnosed with pycnodysostosis, was admitted with a right femur fracture as a result of a low energy trauma. Radiographic studies showed bilateral femur fractures, proximal fracture and non-union in antecurvatum of the left tibia. Pycnodysostosis is a rare disease, generally diagnosed at an early age by growth restriction, frequent fractures or fractures with low energy trauma. Therapy alternatives are limited, and no permanent cure has been developed. If a patient has dysmorphic facial features and fractures in a pathological bone, it is important to suspect bone dysplasia, such as pycnodysostosis and its differential diagnoses.
