    ObjetivoEvaluar los patrones morfológicos lesiónales en parálisis obstétricas del plexo braquial encontrados en 27 casos.Materiales y MétodosSe evaluó retrospectivamente los datos de las historias clínicas de 27 exploraciones microquirúrgicas realizadas durante el periodo de los años 2009-2012. Se usó la clasificación clínica de Narakas. Se comparó los hallazgos operatorios con el patrón clínico de lesión.ResultadosSe observaron 17 patrones diferentes de lesión. Las parálisis totales mostraban el mayor tipo de diversidad lesional, presentando en general roturas de raíces altas con avulsiones de raíces bajas. El compromiso clínico de la raíz de C7 no siempre se correlaciono con los hallazgos quirúrgicos.ConclusiónLas parálisis obstétricas del plexo braquial muestran una gran diversidad de lesiones. La cirugía es altamente demandante, requiriendo el manejo de todas las estrategias de reconstrucción para poder ser usadas dependiendo de acuerdo a los hallazgos quirúrgicos.

    BackgroundTo determine the morphological patterns of obstetrical brachial plexus lesions in 27 cases.Methods The clinical records of 27 microsurgical reconstructions of brachial plexus, performed between 2009 and 2012 were evaluated. Narakas classification was used and the surgical findings were compared with the clinical patterns.ResultsEighteen different types of anatomical lesions were found. The major diversity of injuries was detected in the group of total brachial plexus palsy. However, rupture of the upper root and avulsion of the lower root were the most frequent patterns. The clinical involvement of C7 root did not always correlate with the surgical findings. The obstetrical brachial plexus palsy has a great diversity of anatomical lesions. The microsurgical exploration and reconstruction is difficult, and it demands the knowledge of all different reconstructions due the diversity of the injury patterns. KEY WORDS: Brachial plexus.
