What are the structures passing though the scalene triangle?
Please correct me if these are wrong or are there more

Scalene triangle made by the anterior and middle scalene muscle in the posterior triangle.
Structures are:
1. Brachial plexus
2. Phrenic nerve

  • Scalene triangle contains brachial plex and subclavian Artery .......
  • Phrenic nerve and subclavian vein lies on the anterior surface of ant scalene muscle and therefore not in the triangle
  • Compression of this triangle causes thoracic outlet syndrome (compression of brachial plx and subclavian artery)
