Cervical spondylosis can cause numbness in the little finger. Cervical spondylosis is divided into 4 types: spinal cord type cervical spondylosis, vertebral artery type cervical spondylosis, nerve root type cervical spondylosis and sympathetic nerve type cervical spondylosis, and the symptoms are different for different types. Among them, neurogenic cervical spondylosis can cause numbness in the little finger, mainly because the cervical 8 nerve roots are compressed, which affects the sensation of the little finger and causes the corresponding symptoms of numbness in the little finger. The numbness of different fingers will be produced by different stages of compression. The compression of cervical 6 nerve root will produce numbness of the thumb and index finger, the compression of cervical 7 nerve root will produce numbness of the middle finger, and the compression of cervical 8 nerve root will produce numbness of the little finger. When this symptom occurs, it is recommended to go to the hospital for a detailed examination and then take appropriate treatment.
