ABSTRACT
The growing rod technique is currently one of the most common procedures used in the management of early onset scoliosis. However, in order to preserve spine growth and control the deformity it requires frequent surgeries to distract the rods. Magnetically driven growing rods have recently been introduced with same treatment goal, but without the inconvenience of repeated surgical distractions. One of the limitations of this technical advance is an increase in radiation exposure due to the increase in distraction frequency compared to conventional growing rods. An improvement of the original technique is presented, proposing a solution to the inconvenience of multiple radiation exposure using ultrasound technology to control the distraction process of magnetically driven growing rods.

OBJECTIVE: To analyse cases of radial head and neck fractures in children and compare them with the literature. METHOD: Retrospective and descriptive study of 21 children with radial head and neck fractures. The following parameters were collected: demographics, comorbidity, classification, treatment, need for rehabilitation, lack of range of motion (ROM), time for recovery and complications. RESULTS: The series included 11 males, and the mean age was 8.3 years. The right side was affected in 14 patients. Twelve cases had an associated ipsilateral elbow injury. According to the Chambers classification, 15 cases belonged to group A, while in the Steele-Graham classification, 12 cases were in group I. Eleven patients were treated with immobilization only, 4 percutaneously, and 6 by open reduction and internal fixation (ORIF). Eleven of them needed rehabilitation and despite this, 8 did not achieve full mobility. The mean time to obtain the greatest ROM was 4.71 months. Eight patients had complications, with the most common being neuroapraxia and valgus deformity of the elbow. DISCUSSION AND CONCLUSIONS: Treatment of paediatric radius head and neck fractures must be step-wise, from immobilization only, manual and/or percutaneous reduction, to ORIF, whichever is less indicated. In this respect, both the transcapital needle and/or removal the radius head should be avoided. The most common complication is lack of supination, especially in cases treated by ORIF. The posterior interosseous neuroapraxia was the most common of the rest of complications.

Objetivo: La lesión de Monteggia es poco frecuente (el 2% de las fracturas de la región del codo) y los casos inveterados son muy raros. A continuación se presentan 3 casos tratados mediante reducción abierta y reconstrucción del ligamento anular con fascia tricipital. Casos clínicos: La edad media de los 3 sujetos era de 7 años (rango de 5 a 9), 2 de ellos eran varones y todos presentaban lesiones tipo i de Bado en el lado derecho. Los 3 recibieron tratamiento mediante técnica de Bell-Tawse modificada por Lloyd-Roberts y Bucknill; en un enfermo se asoció osteotomía cubital. Resultados: No se presentaron complicaciones. Tras un seguimiento medio de 35 meses (rango de 9 a 84) todos los sujetos consiguieron un arco de flexoextensión funcional con una pérdida leve de pronosupinación, pero no se detectaron restricciones en las actividades de la vida diaria ni déficit funcional. Conclusiones: La técnica de Bell-Tawse modificada es un método efectivo, aun cuando produce una pérdida leve de movilidad, especialmente de pronosupinación. Los resultados a largo plazo de esta técnica son mejores que los que se consiguen con la escisión tardía de la cabeza radial luxada (AU)
Purpose: Monteggia injuries are a rare occurrence (2% of all elbow fractures), and inveterate cases are extremely unusual. We present 3 cases treated by means of open reduction and reconstruction of the annular ligament with a strip of triceps fascia. Case reports: The mean age of the 3 patients was 7 years (range: 59). Two of them were male and all presented with type 1 Bado injuries on the right side. All 3 were treated by means of the Bell-Tawse technique as modified by Lloyd-Roberts and Bucknill; one of the patients was also subjected to ulnar osteotomy. Results: There were no complications. After a mean follow-up of 35 months (range: 984) all patients achieve a functional flexion-extension range. They experienced a slight loss of pronosupination but they reported no restrictions to their activities of daily living or any functional impairment. Conclusions: The modified Bell-Tawse technique is an effective method, even if it leads to a slight loss of mobility, especially in terms of pronosupination. The long-term results of this technique are better than those achieved with a late excision of the dislocated radial head (AU)
