The purpose of this study was to evaluate 4 patients with marked atrophy of the shoulder girdle muscles caused by degenerative processes of cervical spine.4 patients presented themselves with deltoid paresis with the absence of sensory deficits or myelopathy. The patients were 3 males and one female. Their age at treatment was from 49 to 74 years-old with an average of 61.7 years old. Their mean follow-up period was 17months (17-29).3 cases underwent a cervical anterior decompression and one case was treated conservatively. The severity of deltoid paralysis was classified into five grades according to the manual motor power test and swallow tail sign. Theclinical outcome of each case was evaluated at pretreatment and at followup with JOA scores. Of 4 patients, three had C4/5 cervical spondylosis and one had C4/5 and C5/6. In the all cases, muscle power had improved significantly from MMT 2 to MMT 5. The JOA scores averaged 65.8 points at pretreatment and 98.8 points at follow-up. It is important for the differential diagnosis of shoulder girdle damage in cervical spondylotic syndrome of rotator cuff tears. The swallow tail sign in diagnosis and treatment was effective for a cervical spondylotic amyotrophy.
