VALBUENA, Sebastián. Patrones de lesión en parálisis obstétricas del plexo braquial: Hallazgos morfológicos en 27 exploraciones microquirúrgicas. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2012, vol.77, n.4, pp.233-239. ISSN 1852-7434.

Background: To 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. Results: Eighteen 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. Conclusion: 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.
