The sternoclavicular syndrome: experience from a district general hospital and results of a national postal survey.
OBJECTIVE
To report our local experience of the sternoclavicular syndrome and sample the experience of other rheumatologists in the UK.


METHODS
We studied case records of 23 patients referred to the Southend rheumatology clinic and data obtained from a postal questionnaire survey of British rheumatologists.


RESULTS
We describe 58 cases (20 males and 38 females, mean age 47.2 yr). The disease was unilateral in 40 patients. Shoulder and/or arm pain (38 cases) with limitation of shoulder movements was an important presenting feature; other presenting features were anterior chest wall pain (14 cases) and neck pain (15 cases). Peripheral joint involvement was seen in 12 cases. Skin rash was reported in 12 cases (psoriasis, 6; acne, 2; none had pustulosis). No patients had symptoms or signs of sacroiliitis, and HLA-B27 was negative in 22 out of 23 patients. 99Technetium scintiscanning showed increased uptake in the sternoclavicular region in 31/34 patients (91.1%), but not in the sacroiliac areas. Plain radiographs were abnormal in 18 cases (sclerosis, 9; erosions, 2; soft tissue swelling, 2; bony expansion, 5). CT and/or MRI scans (available in 27 cases) showed erosions in 12 and osteitis in 18. Available histology showed a variable picture, including inflammation, bone erosion, sterile osteomyelitis and fibrosis. The majority of patients (45) were treated with non-steroidal anti-inflammatory drugs: 12 received steroids and 10 received disease-modifying anti-rheumatic drugs (methotrexate, 4; sulphasalazine, 6). Follow-up information was available for 38 patients, of whom 14 became asymptomatic and 24 had chronic disease with intermittent flares.


CONCLUSIONS
Sternoclavicular disease is not uncommon in the UK. It can present with pain in the shoulder, neck or anterior chest wall, and may be underdiagnosed. Our results do not show a link with acne or pustulosis. Features of spondyloarthropathies, such as sacroiliitis and HLA-B27 positivity, were rare in this survey.
