ABSTRACT
Introducción: Las fracturas Salter-Harris VI son lesiones cuya característica es la ablación del anillo pericondral. Son infrecuentes, pero potencialmente devastadoras. El objetivo de este estudio fue evaluar el mecanismo, el tratamiento y los resultados funcionales de estas lesiones en pie y tobillo. Materiales y Métodos: Se analizaron retrospectivamente todos los pacientes con lesiones Salter-Harris VI de tobillo y pie, tratadas entre enero de 2010 y enero de 2013. Se documentaron datos demográficos, clasificación, mecanismo de lesión, tipo de lesiones asociadas y número de cirugías necesarias. La evaluación funcional se realizó con el puntaje de la AOFAS y se tomaron radiografías para determinar viabilidad de la fisis, acortamiento o deformidad angular. Resultados: Se analizaron 5 fracturas (4 pacientes). La edad promedio fue de 7.5 años (rango 6-10 años). El seguimiento promedio fue de 26.2 meses. Tres lesiones se produjeron por accidentes de moto y 2, por auto versus peatón. Todos los casos se acompañaron de pérdida de sustancia, el 75% tenía lesiones en más de un hueso y el 50%, lesiones tendinosas asociadas. Cada paciente requirió un promedio de 3,2 cirugías. El puntaje de la AOFAS promedio fue de 79.8 (rango 62-100). Sólo el 40% de las fisis afectadas permanecían viables al último control. Conclusiones: Las fracturas Salter-Harris VI se acompañan de una gran variedad de lesiones asociadas, requieren múltiples cirugías, suelen producir un cierre precoz de la fisis y algún grado de discapacidad. Se requieren medidas preventivas para evitar la exposición de los niños a este tipo de lesiones. Nivel de evidencia: IV - Serie de casos.
Background: Salter-Harris VI fractures (SHVI) are injuries in which part of the physis is missing. They are rare in children but potentially devastating. The aim of this study was to evaluate the mechanism of production, treatment, and functional outcomes of these injuries in the foot and ankle. Methods: All patients with foot and ankle SHVI injuries treated between January 2010 and January 2013 were retrospectively analyzed. Demographics, classification, mechanism of injury, type and number of associated injuries that required surgery were documented. Patients were assessed functionally with the AOFAS score and a radiological evaluation was performed to determine the viability of the physis, limb length discrepancies or angular deformities. Results: Five fractures in 4 patients were analyzed. The average age at injury was 7.5 years (range 6-10 years). Mean follow-up was 26.2 months (range 12-37 months). Three injuries occurred as a result of motorcycle accidents, and 2 in a car accident. All were associated with soft-tissue injuries, 75% had more than one injured bone and 50% had tendon lesions. Each patient required an average of 3.2 surgeries (range 2-5). The average AOFAS was 79.8 points (range 62-100). Radiographically, only 40% of the affected physis remained viable at last follow-up. Conclusions: SHVI fractures are associated with several injuries, require multiple surgeries and often result in premature growth arrest and some degree of disability. Prevention measures are required to avoid the exposure of children to this type of injury.

As estruturas responsáveis pelo crescimento do osso incluem a fise (também chamada placa de crescimento) e as epífises. Afecções que acometem pacientes com o esqueleto imaturo, ou seja, com a placa de crescimento ainda aberta, podem interferir no crescimento ósseo, resultando em complicações como parada do crescimento, encurtamento dos membros ou deformidades angulares. Condições traumáticas que resultam muitas vezes em fraturas epifisárias são a causa mais comum das lesões da placa de crescimento. A avaliação cuidadosa desses pacientes pelos métodos de diagnóstico por imagem atualmente disponíveis, sobretudo a radiografia, a tomografia computadorizada e a ressonância magnética, permite o reconhecimento precoce do comprometimento das estruturas relacionadas ao crescimento ósseo, além de tratamento adequado, diminuindo a possibilidade do desenvolvimento de tais complicações.
The structures responsible for the growth of bones include the physis (also called growth plate) and the epiphysis. Affections involving patients with immature skeletons, i.e., with a still open growth plate, may affect the bone growth, resulting in complications such as growth arrest, limb shortening and angular deformities. Traumatic conditions, many times resulting in epiphyseal fractures, are the most frequent cause of growth plate injuries. A careful evaluation of these patients by means of currently available imaging methods, especially radiography, computed tomography and magnetic resonance imaging, allows an early diagnosis of the involvement of structures related to the bone growth, besides an appropriate management, reducing the probability of secondary complications.
