Summary

This study on brachial plexus injuries (BPI) in Angola found low functional recovery rates due to delayed surgery. Lessons learned emphasize the need for comprehensive teams and partnerships to improve pediatric BPI care.

Area of Science:

  • Neurosurgery
  • Orthopedic Surgery
  • Global Health

Background:

  • Brachial plexus injuries (BPI) present significant challenges in low- and lower-middle-income countries.
  • Establishing effective surgical programs requires understanding patient profiles and logistical constraints.

Purpose of the Study:

  • To present a national prospective cohort study of neonatal and adult BPI in Angola.
  • To analyze clinical data, surgical outcomes, and lessons learned for improving BPI care.
  • To provide insights applicable to other resource-limited settings.

Main Methods:

  • A multicenter national prospective cohort of neonatal and adult BPI patients from January 2021 to December 2025.
  • Pre-operative clinical evaluation by a nerve surgeon; adult patients also underwent electromyography.

  • Standardized surgical procedures and post-operative follow-up by the same surgeon.

    • Main Results:

    • Included 16 neonatal and 86 adult BPI cases.
    • Functional recovery (MRC grade ≥3) was achieved in 43% of neonatal patients.
    • Adult patients had a mean injury-to-surgery interval of 14 months; 98% experienced neuropathic pain with 90% improvement post-surgery.

    Conclusions:

    • Low functional recovery rates are linked to delayed surgical intervention in both pediatric and adult BPI.
    • Successful BPI treatment necessitates a multidisciplinary approach, including dedicated pediatric teams and public-private partnerships.
    • The study highlights critical lessons for developing sustainable brachial plexus surgery programs in resource-limited environments.
