Cervical rib syndrome is a complex clinical syndrome caused by the compression of important vascular nerves in the thoracic outlet area, also known as cervicothoracic outlet syndrome, anterior oblique muscle syndrome, pectoralis minor syndrome, rib lock syndrome, excessive abduction syndrome, etc. It is a general term for a series of vascular and neurological symptoms of the upper limbs caused by the compression of the brachial plexus nerve and subclavian artery at the outlet of the upper thoracic outlet for some reasons. The main clinical manifestations are pain and numbness in the shoulder, arm and hand, or even muscle atrophy and weakness, cold and purple hands, and weakened radial artery pulsation. X-ray is an electromagnetic wave with a certain wavelength and frequency, and has wave-particle duality. X-ray imaging takes advantage of the energy conversion that occurs when it interacts with matter, highlighting the particulate nature. About 0.5%-1.0% of the population has cervical ribs, about half of them are bilateral, more common in women, cervical ribs are ribs growing on both sides or on one side of the 7th cervical vertebra, sometimes symptoms of brachial plexus nerve compression can occur, including the whole cervical vertebra or the whole thoracic vertebra, cervical ribs are often thin and short, sometimes fused with transverse processes, their edges are not very neat, but cervical ribs can also be shaped like normal The cervical ribs are often thin and short, sometimes fused with the transverse process, and their edges are not very neat.
