The scalene muscles generally are known as pectoralis minor or subclavius muscle can cause upper limb pain (Torriani et al.).
Numerous factors can lead to its extrinsic compression, including anomalous subclavius or scalenus anterior, a long transverse process of the cervical spine, cervical rib, abnormal insertion of the first rib, congenital fibromuscular bands, or narrowing of the costoclavicular space from the depression of the shoulder [3,10].
Their treatment included thoracic outlet decompression via complete anterior and middle scalenectomy, brachial plexus neurolysis, excision of subclavius muscle tendon, and resection of the first rib.
Further detail is provided in Gray's Anatomy (Standring 2005), which states that the clavicle, subclavius, SCM and omohyoid, lateral part of the carotid sheath, phrenic nerve, transverse cervical, suprascapular and ascending cervical arteries, subclavian vein, prevertebral fascia, and phrenic nerve are all anterior to scalenus anterior.
Damage can express itself not only in soreness, but in headaches when the rhomboids, trapezius, subclavius and pectoralis minor are overused.
Subclavius posticus is a rare anatomic variation of the subclavius muscle, which is almost invariably inserted on the first costal cartilage and runs dorsally and posteriorly over the cords of the brachial plexus and subclavian vessels.

The upper trunk was giving suprascapular nerve and nerve to subclavius. Both upper and lower trunks divide into ventral and dorsal divisions.
The sternocleidomastoid and the subclavius muscles also have points of attachment to the clavicle.
