Manubriosternal joint dislocation in contact sport.

A 17 year old man developed chest pain and shortness of breath immediately after a scrummage while playing rugby football. A lateral chest radiograph showed a dislocated manubriosternal joint, with no associated injuries. This has not been previously reported in a sporting setting. This injury should be considered in flexion-compression injury of the thorax.

The ribs: anatomic and radiologic considerations.

The ribs are essential structures of the osseous thorax and provide information that aids in the interpretation of radiologic images. Techniques for making precise identification of the ribs are useful in detection of rib lesions and localization of lung lesions. The big rib sign and the vertical displacement sign can be used to differentiate the right and left ribs on lateral chest radiographs. The clavicle, the xiphoid process, and the sternal angle may be used as anatomic landmarks for rib counting on computed tomographic scans. For rib counting on lateral chest radiographs, the sternal angle or the 12th rib may be used. Anatomic rib variants include developmental deformities, cervical rib, and short rib and may mimic true rib diseases. Detection of thoracic deformities such as funnel chest (pectus excavatum) and barrel-shaped thorax requires an awareness of the strong correlation between the transverse appearance of the thorax and costal shape. Shadows around the rib cage (eg, rib companion shadows, sharp lines along the lower margin of the ribs, rib overlying shadows) may mimic pleural and extrapleural disease on frontal chest radiographs. It is imperative that the radiologist be familiar with normal rib anatomy, normal rib variants, and the radiologic appearance of the ribs to prevent misdiagnosis.

Trisomy 21 in newborn infants: chest radiographic diagnosis.

Chest radiographs of 30 infants with trisomy 21 and 881 unaffected infants were evaluated for the following findings common in trisomy 21: multiple manubrial ossification centers, 11 rib pairs, and a bell-shaped chest. Radiographs were obtained in the first 48 hours of life. Of the 881 unaffected infants, 85 (9.6%) exhibited multiple manubrial ossification centers; 46 (5.2%), 11 rib pairs; and 208 (23.6%), bell-shaped chest. Of the 30 infants with trisomy 21, 24 (80%) exhibited multiple manubrial ossification centers; ten (33%), 11 rib pairs; and 24 (80%), bell-shaped chest. The probability of trisomy 21 in routinely radiographed newborn infants is 0.05% when none of the three findings is present, 1.6% with multiple manubrial ossification centers alone, 0.2% with 11 rib pairs alone, and 0.7% with bell-shaped chest alone. The probability of trisomy 21 increases in patients with two findings and reaches 58.4% in patients with all three findings.

Sternal-manubrial separation as a complication of marrow aspiration in a patient with protein-calorie malnutrition and osteoporosis.

A simple needle aspiration of marrow from the sternum was performed in a middle-aged woman with severe protein-calorie malnutrition and osteoporosis. Though carefully performed, a separation of the sternal-manubrial junction occurred with pain but no other serious sequelae. The subject of complications from marrow aspiration for diagnostic and therapeutic purposes is discussed.

Thymic abscess with bacteremia and manubriosternal pyarthrosis in a geriatric patient.

We describe a geriatric patient with acute substernal chest pain thought to be due to coronary heart disease, who was subsequently found to have Staphylococcus aureus bacteremia associated with infection of the thymus and manubriosternal joint. To our knowledge, this is the first report of (1) a thymic abscess in a geriatric patient, (2) a thymic abscess associated with bacteremia, (3) extra-articular extension of manubriosternal pyarthrosis, and (4) manubriosternal pyarthrosis in the geriatric age group.

The manubriosternal joint in rheumatoid disease.

Manubriosternal joint abnormalities are often undetected causes of chest pain. Twenty-five normal patients and 40 cadaver specimens were evaluated to establish the normal radiographic anatomy of this articulation. Analysis of the manubriosternal joint was carried out in rheumatoid diseases in order to ascertain the incidence and variety of abnormalities. Twenty-seven of 100 manubriosternal joints were abnormal in rheumatoid arthritis. Of 25 patients with ankylosing spondylitis 20 (80%) revealed abnormalities either with erosions or fusion. None of 25 patients with psoriatic arthritis and none of 20 with Reiter syndrome showed erosions or ankylosis. The articulation should be evaluated in rheumatoid diseases and in non-arthritic patients with chest and/or shoulder pain.

A unified approach to symptomatic juxtasternal arthritis and enthesitis.

Symptomatic arthritic and enthesopathic conditions of the sternum and its articulations have not been studied well as a group, despite previous reports of individual diseases and radiographic abnormalities that affect these structures. The lack of a unified clinical approach has been partly due to the absence of a name for the clinical condition, which we propose to call juxtasternal arthro-osteitis. Although juxtasternal arthro-osteitis may be caused by septic arthritis, this study was based on 24 adult patients with noninfectious juxtasternal arthro-osteitis, collected retrospectively from records of patients who had sternal tomography and from rheumatology clinic populations. Twelve of the patients had an underlying systemic arthropathy that met standard diagnostic criteria; three patients had an unclassifiable systemic arthropathy; and nine patients had the idiopathic localized disease, which has been termed sternocostoclavicular hyperostosis. Radiographic findings in the various diseases followed definite trends, but were not sufficiently distinct to provide the sole basis for diagnosis. Initial failure to correlate dermatologic, rheumatologic, radiographic, and laboratory findings led to prolonged delays in diagnosis in many cases. When juxtasternal arthro-osteitis is encountered, a thorough evaluation should be made for systemic disease. Idiopathic sternocostoclavicular hyperostosis can be diagnosed only after systemic arthropathy or enthesopathy has been excluded.

Pyarthrosis of the manubriosternal joint.

This is a case report of primary osteomyelitis of the sternum, the only case of pyarthrosis of the manubriosternal joint the authors are able to find in the American literature. The diagnosis was established by tomogram and open biopsy. The treatment was thorough and specific antibiotic coverage.
