Role of early shoulder tomography on the obstetric brachial plexus palsy

ABSTRACT

Objective: To demonstrate the importance of performing early shoulder tomography in patients with obstetric brachial plexus palsy (OBPP). Methods: This series of cases retrospective study with level evidence IV was conducted by consulting 76 patient's medical records with OBPP divided into three age groups: ≤12 months, 13 to 24 months and ≥ 25 months. The patients were classified according to gender, affected side, type of paralysis according to Narakas classification, and by computed tomography, according to the Waters scale. Results: The association between the age groups with Waters classification was statistically significant (p=0,006), showing that patients in the group aged less than 12 months and in the group aged between 12 and 24 months had a relevant correlation between the physical examination and Waters > III when compared to patients from groups aged 25 months or older. Conclusion: This study shows a correlation between the findings in the physical examination and severe dysplasia on the shoulder of children under 24 months of age, justifying the early tomographic shoulder exam in order to achieve a better follow-up and a consider a more aggressive approach in the treatment of OBPP affected children.
