A radiographic technique is described for the symmetrical visualization of the sternoclavicular joints in the anteroposterior projection. A short focal-spot patient distance is used with an ultra-fine focal-spot tube, so that differential magnification projects the sternoclavicular joints to either side of the thoracic spine. The supine position is comfortable for the symptomatic patient. Motion studies are made.
Among the joints of the shoulder region, the sternoclavicular joint (SJ) is under the most stress. Dragging pains emanating towards the neck and the lateral parts of the shoulder are typical complaints, although swelling of the SJ is rarely observed. Degeneration of the fibrocartilagenous disc should be considered when swelling is present, especially in the case of recurrent pains lasting for several months and swelling excluding inflammatory diseases, rheumatism and degenerating arthrosis. Above all we are interested in examining discopathy of the SJ joint and, in case of unsuccessful conservative measures, effective surgical therapy. We recommend the opening of the SJ, the resection of the degenerated disc and, finally, a tight capsulorrhaphy. Six patients operated in this way showed very positive post-operative results.
Symptomatic recurrent anterior dislocation of the sternoclavicular joint is a rare but sometimes painful condition. A novel technique of extrathoracic reconstruction using tendon autograft is presented in this case report. When spontaneous ankylosis of an anterior dislocation of the sternoclavicular joint does not occur, and the patient remains symptomatic, surgical reconstruction using this procedure may be a viable alternative.
Chronic anterior sternoclavicular joint (SCJ) instability may cause pain and persistent functional limitation in active patients. Although SCJ reconstruction and medial clavicular resection have been advocated in these situations, the results of surgical treatment are not well characterized. The purpose of this investigation was to determine the functional outcome of surgical treatment in adolescent and young adult patients with chronic recurrent anterior SCJ instability. Fifteen patients with chronic recurrent anterior SCJ instability refractory to nonoperative therapy who underwent joint reconstruction or medial clavicular resection were evaluated for pain and function using the American Shoulder and Elbow Surgeons (ASES) Standard Shoulder Assessment Form and the Simple Shoulder Test (SST). At average follow-up of 55 months, the mean ASES score was 85 and the mean SST score was 10.9. Sixty percent of patients reported stable, pain-free joints, although 87% (n = 13) reported some limitations of athletic or recreational activity. There were no surgical complications, and no patient underwent subsequent revision procedures. Although subsequent activity modification is often required, surgical treatment of chronic anterior SCJ instability in adolescents and young adults can provide near-complete pain relief and return of shoulder and upper extremity function.
OBJECTIVE: The sternoclavicular joint (SCJ) is commonly affected by rheumatological conditions. Case reports suggest that it may refer pain to distant areas, potentially leading to delays in diagnosis and inappropriately targeted investigations. Therefore, we studied the patterns of pain referral from the SCJ of nine healthy volunteers. METHODS: Hypertonic saline was injected into the SCJ of nine normal volunteers and the location of any resulting pain was noted, as was the effect of resisted shoulder abduction and flexion. Composite pain maps were then constructed from individual pain diagrams. RESULTS: An unpleasant, deep aching pain was produced locally in eight subjects and referred to distant sites in all subjects. Tests of shoulder movement had varied and inconstant effects. CONCLUSIONS: We demonstrated that the SCJ is capable of referring pain to areas distant from the joint. Knowledge of these referral patterns will enable the SCJ to be considered in patients with pain in these areas.
We describe the first reported instance of sternoclavicular pyarthrosis caused by Streptococcus anginosus-constellatus. Infections caused by this organism are unusual in a nonimmunocompromised host. Common conditions predisposing to sternoclavicular joint infection were not present. A possible mechanism for the infection is offered.
Traumatic injuries of the acromioclavicular and sternoclavicular joints are discussed. Treatment of acromioclavicular trauma is symptomatic, except for type III injuries with marked prominence of the clavicle, for which open reduction and internal fixation are recommended. Sternoclavicular injury with no instability requires only symptomatic treatment; acute dislocations should be reduced.
Septic arthritis of the sternoclavicular joint (SCJ) is a rare disorder, and is usually associated with predisposing factors such as contiguous foci of infection, heroin addiction, rheumatoid arthritis and diabetes mellitus. Three cases in previously healthy adults are reported here. The aetiology, clinical manifestations and treatment are briefly reviewed. The considerable difficulty in diagnosing this disorder in adults is emphasized. In summary, diagnosis of septic arthritis of the SCJ in adults requires a high index of suspicion, and must be considered not only in patients with predisposing factors, but also in previously healthy adults.
The rare case of limited range of motion of the shoulder due to ankylosis of the sternoclavicular joint in SAPHO syndrome is presented. The symptoms and the resection arthroplasty of the sternoclavicular joint are discussed.
The sternoclavicular (SC) joint can be affected by a wide variety of pathologic conditions. Imaging is usually needed for diagnosis and staging. Although the use of magnetic resonance (MR) imaging has become indispensable in the evaluation of most joints, MR has received little attention in SC joint evaluation. Recently, however, it has been shown that detailed MR images of the normal SC joint can be obtained. This pictorial essay explores the differential diagnosis of the abnormal SC joint and helps to determine the role of MR imaging in the SC joint imaging algorithm.
Injuries to the sternoclavicular (SC) joint are infrequently encountered. However, retrosternal SC joint dislocations are potentially life-threatening injuries which must be recognized by the examining physician and treated as soon as possible. Plain radiography often fails to fully distinguish SC joint injuries, and computed tomography has emerged as the diagnostic modality of choice for defining the injury complex and surrounding injuries. We have encountered 6 cases of SC joint injuries over the past 3 years and describe their presentation and management.
A 60-year-old man in good health with no history of intravenous drug abuse was hospitalized for sternoclavicular joint pain and swelling. His complicated course required extensive debridement of the sternoclavicular joint. An insidious course, negative blood culture and requirement for surgery is common in infections of this joint.
Computed tomography (CT) was used to examine 17 patients with various pathologic conditions (trauma, neoplasm, infection, or arthropathy) involving the sternoclavicular joint or sternum. CT required less time to perform and caused less discomfort to the patient than did conventional linear tomography. CT also demonstrated abnormalities better or provided additional useful diagnostic information in the majority of patients. When plain radiographs are not conclusive, CT is the preferred radiologic modality for the evaluation of the sternoclavicular joint and sternum.
Primary open reduction and fixation with Kirschner wires and/or fascia lata or PDS is recommended in the treatment of acute traumatic luxations of the sternoclavicular joint. If not bent or secured against migration, K-wires may be the reason for lethal postoperative complications. We report on 7 own patients with luxation of the sternoclavicular joint and discuss the problems in diagnosis, operative and postoperative treatment of this rare lesion.
Posterior dislocation of the sternoclavicular joint is an uncommon injury. Since 1824, when Sir Astley Cooper described the injury, little more than 100 cases have been described, and the majority of these have been in the last decade, identified by computed tomography. The significant morbidity and mortality associated with this injury is based upon serious damage to important anatomical structures found in the vicinity of the joint. We present a case report, describe the relevant clinical anatomy of this region, and review associated complications.
An adult patient with isolated septic arthritis of the sternoclavicular joint (SCJ) caused by Staphylococcus aureus is described. The patient had no underlying diseases other than paronychia, which might have served as the portal of entry. Antibiotic therapy resulted in clinical cure but x-ray revealed progression of the destructive process.
A 45-year-old woman presented with one-year history of a mass on her chest. Computed tomography and magnetic resonance imaging demonstrated a tumour near the sternoclavicular joint. The tumour was diagnosed as osteolipoma histologically after resection. Osteolipoma is a rare tumour and this may be the first report of osteolipoma arising adjacent to the sternoclavicular joint.
