The clavicular fossa is divided into the supraclavicular fossa, which has no tendons, and the infraclavicular fossa, which has some tendons, mainly the clavicular ligament, which can be divided into the trapezius and conus ligaments that stabilize the acromioclavicular joint and hold the clavicle in its normal anatomic position. The clavicular fossa is a depression with subcutaneous tissue beneath the skin and no other soft tissue. Some people have a more pronounced clavicular fossa, others less so, and they usually do not cause significant pathologic changes and do not require specific treatment. If the patient’s clavicular ligament is torn and broken after trauma, it can easily cause a dislocation of the acromioclavicular joint and can easily lead to strain and edema of the clavicular ligament after excessive pressure. There will be significant pain in the area of the subclavian fossa when pressure is applied, and there will also be pain in the subclavian area and pain in the subclavian fossa when the shoulder is lifted.
