Forearm and elbow secondary surgical procedures in neonatal brachial plexus palsy: a systematic scoping review

Abstract

IntroductionNeonatal Brachial plexus palsy (NBPP) is an injury during delivery that can lead to loss of motor function and limited range of motion in patients due to damage of nerves in the brachial plexus. This scoping review aims to explore types of procedures performed and assess outcomes of forearm and elbow secondary surgery in pediatric patients. MethodsSearches of PubMed, Cochrane, CINAHL, Web of Sciences and Scopus were completed to obtain studies describing surgical treatment of elbow and forearm in pediatric patients with NBPP. 865 abstracts and titles were screened by two independent reviewers resulting in 295 full text papers; after applying of inclusion and exclusion criteria 18 articles were included. The level of evidence of this study is level IV. Results10 main procedures were performed to regain function of the forearm and elbow in neonatal brachial plexus birth palsy patients. Procedures had different aims, with supination contracture (6) and elbow flexion restoration (5) being the most prevalent. The variance between pre-and postoperative soft tissue and bony procedures outcomes decreased and showed improvement with respect to the aim of each procedure category. For soft tissue procedures, a statistically significant increase was found between pre- and postoperative values for active elbow flexion, passive supination, and active supination. For bony procedures, there was a statistically significant decrease between pre- and postoperative values of passive and active supination. ConclusionsOverall, all procedures completed in the assessed articles of this study were successful in their aim. Bony procedures, specifically osteotomies, were found to have a wider range of results, whereas soft tissue procedures were found to be more consistent and reproducible with respect to their outcomes. Bony and soft tissue procedures were found vary in their aims and outcomes. This study indicates the need for further research to augment knowledge about indications and long-term benefits to each procedure.
