We saw a 55-year-old male patient in our clinic who presented with a complaint of right shoulder and back pain and difficulty in movement. The patient complained that he had been diagnosed with “frozen shoulder” and had been treated with shoulder joint closure, physical therapy, and topical ointment. After each treatment, the condition improved, but the symptoms would reappear soon afterwards. Through further questioning, we learned that the patient had no history of overuse of the shoulder joint due to her ambulatory work. Physical examination revealed that the patient’s shoulder joint signs were not obvious, and although the active mobility was reduced, the passive activity was not significantly limited. Moreover, the patient had pressure pain in the muscles of the cervical spinous process, paraspinal process, and medial border of the scapula, and the brachial plexus nerve pull test was weakly positive. Therefore, we recommended that the patient take an X-ray of the shoulder joint and cervical spine, which showed degenerative changes in the cervical spine and narrowing of the right intervertebral foramen of C4-6, but no significant changes in the shoulder joint. This patient was finally diagnosed with cervical spondylosis and cervicogenic frozen shoulder. The patient was instructed to brake the neck, take methylcobalamin capsules and cervical relief pellets orally, add celecoxib or aminoglycoside enteric tablets when the pain was obvious, and treat the neck and shoulder with topical blood-activating and pain-relieving cream, etc. After 1 week, the patient’s condition improved significantly, and the non-steroidal anti-inflammatory drugs were stopped and nerve-nourishing drugs continued to be given.
