Abstract
Objective To evaluate elbow flexion in children with obstetric brachial plexus paralysis submitted to Oberlin transfer. Methods Retrospective study with 11 patients affected by paralysis due to labor who did not present spontaneous recovery from elbow flexion until 12 months of life, operated between 2010 and 2018. Results The children were operated between 5 and 12 months of life, with a mean of 7.9 months, and the mean follow-up time was 133.2 months, ranging from 37 to 238 months. Six patients (54.5%) presented a degree of muscle strength ≥ 3, measured by the strength scale of the Medical Research Council (MRC) and, according to the active movement scale (AMS), 5 patients obtained a score of ≥ 5. A negative correlation was identified between the AMS and the Narakas classification (r = -0.509), as well as between the strength scale (MRC) and the Narakas classification (r = -0.495). A strong positive correlation was observed (r = 0.935) between the AMS and the MRC demonstrating that the higher the score on the movement scale, the higher the score on the muscle strength scale. Conclusion The Oberlin surgery is a possible option for recovery of elbow flexion in children with neonatal plexopathy, demonstrating, however, very heterogeneous results, even in the long-term follow-up.
