Protruding bones below the neck may be due to the following reasons: 1. Normal bony protrusions. There are relatively prominent bony protrusions in the lower part of the neck itself, such as the sternal head of the bilateral clavicles and the cervical spine spine at the back of the neck. These bony protrusions are more obvious when the patient is thin or in a particular position.2. Misalignment of the small joints of the cervical spine, if the small joints of the cervical spine are disturbed due to trauma to the neck or prolonged sitting and standing with the head down, then it is possible to see abnormal bony protrusions in the neck.3. Old injuries to the neck, such as old fractures and dislocations of the cervical spine, may be seen during the recovery process.4. Then there may be excessive osteophytes during its recovery process, which then leads to abnormal bony protrusions.4. Degenerative changes in the cervical spine, such as straightening of the physiological curvature of the cervical spine, retroflexion, or osteophytes in the cervical spine, can lead to abnormal bony protrusions in the cervical spine.
