Conclusion
Almost half of the evaluated plexuses had collateral variations, particularly in subscapular nerves.
Supporting Evidence
- 47.1% of the evaluated plexuses had collateral variations.
- Subscapular nerves were the most varied structure.
- Long thoracic nerve variations were present.
- Further studies are needed to confirm these variations.
Takeaway
The study looked at the nerves in the arm and found that many of them can be different than what doctors usually expect, which is important for surgeries.
Methodology
Anatomy of brachial plexus structures from 46 male and 11 female cadaverous specimens was studied using parametric measures.
Limitations
The study's sample size was small, and the cause of death for each cadaver was not known in detail.
Participant Demographics
46 male and 11 female mixed-race cadaverous specimens aged 40–80 years.
