Compared with acromioclavicular dislocation, dislocation of the clavicle at its sternal end is uncommon and accounts for 3% of all injuries to the shoulder girdle. Furthermore, the posterior dislocation of the sternoclavicular joint is relatively a rare injury compared to the other types of sternoclavicular dislocation. We report this case since we have experience with similar cases of traumatic posterior dislocation at the sternoclavicular joint, which were successfully treated with x-ray guided reduction.

Dislocation of the clavicle at its sternal end is relatively rare, as compared with acromioclavicular dislocation. Among them, the posterior dislocation of the sternoclavicular joint was extremely rare. So, not more than fifty cases had been reported in the literature. Of these three main typesanterior, superior, and posterior-the anterior one is by far the most common. Most authors have stressed the difficulty in confirming the diagnosis with routine radiographs. We experienced a case of traumatic posterior dislocation of the sternoclavicular joint treated successfully by manipulative reduction. So, we report it with review of literature.

Bipolar clavicular dislocation is simultaneous dislocation of both poles of the clavicle (mainly an anterior dislocation of the sternoclavicular joint and a posterior dislocation of acromioclavicular joint) and rarely reported. We report a case of bipolar claviclular dislocation after a seat belt injury and describe its presumed mechanism and treatment with a review of literature.

PURPOSE: To assess the clinical features and the outcomes of conservative treatment of condensing osteitis of the medial end of the clavicle. MATERIALS AND METHODS: We reviewed 24 patients among 44 patients with pain and protrusion on the medial clavicle, who were diagnosed as condensing osteitis and followed over one year between April 2003 and August 2008. Plain radiograph and laboratory examination (24 cases), bone scan (12 cases), computed tomography (3 cases), MRI (1 case) and biopsy (1 case) were performed. Patients were followed with UCLA score, VAS (Visual Analogue Scale) and change of protrusion. RESULTS: In all cases, mild sclerosis and expansion were seen at the medial clavicle and sternoclavicular joint was preserved. Laboratory examination showed nonspecific results but various abnormal findings. Protrusion was not changed in 20 cases (83%) and decreased in 4 cases (17%). VAS for pain was improved from 3.4 to 1.2 and VAS for function was improved from 25.5 to 29.1. UCLA score was improved from 28.8 points to 33.7 points. CONCLUSION: Physical and radiologic examination was important for diagnosis of condensing osteitis and laboratory exmination was useful to differentiate it from other diseases. Conservative treatment with rest and nonsteroidal anti-inflammatory drugs showed satisfactory result.

Sternoclavicular joint posterior dislocations are considered a very uncommon, and type of injury where if esophagus or airway injury occurs behind the clavicle, it poses a high risk to the patient. In addition, if epiphyseal fracture occurs as a result of the sternoclavicular joint posterior dislocation, surgical treatment is often required. However, in the absence of a complete ossification of the clavicle, it is difficult to differentiate between a simple dislocation and epiphyseal fracture-dislocation solely based on simple radiographs or computed tomography scans. In this case report, the authors present a case in which a sternoclavicular joint posterior dislocation was diagnosed in a 14-year-old male athlete. The case report discusses how the posterior dislocation without epiphyseal fracture was diagnosed using an ultrasound and subsequently treated with successful outcomes using manual reduction. The case report presents our findings along with discussion that includes a literature review of relevant research.

Ganglion cysts are most common on the dorsum of the hand or wrist, but they can occur in any part of the body. There have been few papers reporting ganglion cysts originating from the sternoclavicular joint, with most of these cases developing in children. A 76-year-old woman was referred to our department because of a painless mass over the right sternoclavicular joint. The mass was excised along with the portion of the sternoclavicular joint capsule surrounding the stalk. Histopathologic examination showed the cyst wall to be composed of compressed collagen fibers without evidence of an epithelial or synovial lining, which was consistent with ganglion cyst. To our knowledge, this is the first report of such a cyst in an adult. We consider this to be a useful report for surgeons that treat mass lesions occurring in almost any part of the body surface.

Reactive arthritis or Reiter's syndrome characteristically affects the joint of the lower limb in an asymmetrical pattern. Usually it does not affect the axial skeleton or upper limbs. Although cases of atraumatic atlantoaxial subluxations have been reported, no case of spontaneous sternoclavicular dislocation in Reiter's syndrome has been reported. This paper describes a case of a 26 year old male patient who developed a spontaneous posterior sternoclavicular joint dislocation. No attempt of reduction was made and the patient was managed conservatively with good results.

PURPOSE: Currently, biomechanics and function comparison of the reconstruction of structures play important roles in the sternoclavicular joint stability is not much. In order to confirm the improvement in the functional aspects of the sternoclavicular joint after the three most widely used reconstruction methods, we measured the degree of anterior translation of the sternoclavicular joint after the operation using cadavers. MATERIALS AND METHODS: We studied 24 sternoclavicular joints in the cadavers. First, we measured the anterior translation of the clavicle, which was compared with the sternum in 24 normal sternoclavicular joints. We divided the cadaver into three groups and performed each of the three current operations: figure of eight hamastring tendon reconstruction operation (Group 1), subclavius tendon reconstruction operation (Group 2), and hamstring tendon reconstruction operation (Group 3); then we compared the degree of anterior translation in each group. We did the measurement by adding 10 degrees to the glenohumeral joint each time from 0 degrees to 90 degrees. RESULTS: In the normal joint, the clavicle was significantly ascended compared with the sternum. The Group 1 had a 1.68±0.25 mm anterior translation while the Group 2 had 1.81±0.23 mm and Group 3 had 2.8±0.58 mm (Group 1: p=0.004, Group 2: p=0.001, Group 3: p=0.002). The Group 1 showed a low ascending rate of up to 60 degrees, which showed no significant difference with that of the normal joint. However, after 60 degrees, the ascending rate showed a significant increase. In the case of Group 2, there was no significant difference with normal joint of up to 50 degrees. Group 3 showed significant anterior ascending from 20 degree. CONCLUSION: Through measuring the anterior translation of subjects that underwent three representative sternoclavicular joint reconstructions, we found that the result from the Group 1 was most comparable normal translation of the sternoclavicular joint.

A 50-year-old male patient was admitted due to right ventricular and aortic foreign bodies with ascending aortic pseudoaneurysm. The patient had a history of Kirschner wire fixation of right sternoclavicular joint 3 months ago. Under cardiopulmonary bypass, two K-wires were removed and injured pulmonary valve leaflet and aortic wall were repaired successfully. The postoperative course was uneventful and the patient was discharged on the 14th postoperative day.
