Pain After Brachial Plexus Injury Surgery: Variability in Reporting

Area of Science:

• Orthopedic Surgery
• Neurosurgery
• Pain Management

Background:

• Brachial plexus injury (BPI) frequently leads to significant postoperative pain and morbidity.
• Current reporting of pain outcomes after BPI surgical reconstruction is inconsistent, hindering clear understanding of treatment efficacy.

Purpose of the Study:

• To systematically review the literature on postoperative pain reporting following surgical treatment for traumatic BPI.
• To assess the variability in pain measurement techniques and reporting intervals in existing studies.

Main Methods:

• A systematic review adhering to PRISMA guidelines was performed.
• Studies included adults with traumatic BPI undergoing operative treatment who reported pain using the Visual Analog Scale (VAS).
• Data extraction focused on the timing and methods of postoperative pain assessment.

Main Results:

• Nine studies met the inclusion criteria, revealing significant heterogeneity in pain reporting.
• Over 15 different postoperative timepoints were reported, with few studies using comparable intervals, precluding pooled analysis.
• Pain was consistently prevalent post-BPI surgery, especially with root avulsion; some techniques showed qualitative pain improvement.

Conclusions:

• Pain reporting after BPI surgery lacks standardization, limiting meaningful outcome comparisons.
• Standardized measurement intervals and reporting methods are crucial for clinical guidance and future research.
• Consistent pain assessment is essential to guide clinical expectations and strengthen evidence-based practices for BPI management.
