[Anatomoclinical forms of fractures of the sternum. Role and methods of osteosynthesis of unstable fractures].

In general, fractures of the sternum are of little interest. This is unfair since unstable fractures may be the cause of paradoxical respiration and hence respiratory distress. Fractures often result from automobile accidents and occur in passengers wearing seat belts. In these circumstances, the seat belt in fact replaces the steering wheel as the causative agent. With reference to several cases this variety of injury is studied from the anatomo-pathological, clinical and therapeutic viewpoints. Osteosynthesis using a plate and screws limited to the sternum or including neighbouring rib fractures would appear to be the method of choice. Surgical fixation of the fracture site, the methods of which are discussed, is of value for both isolated lesions of the thoracic cage, and also in the context of single stage surgery in certain patients with multiple trauma.

An alternative to the standard radiographic position for the sternum.

Radiography of the sternum can be difficult to perform in an ambulatory patient experiencing acute pain. This article describes an alternative positioning method of demonstrating the sternum utilizing the standing position. The technique enables the production of optimal radiographs and increases patient comfort.

[Spontaneous fracture of the sternum].

Spontaneous fractures of the sternum are unusual. They can simulate cardio-thoracic emergencies. A case of stress fracture of the sternum and of the femoral neck in a patient with corticosteroid induced osteoporosis is reported and the peculiar value of CT assessing the absence of tumoral mass is emphasized.

[Surgical treatment of pectus excavatum by "turn over" of the sternum].

Operations were performed on 20 children for Pectus excavatum in five years. 'Turn over' of the sternum was chosen as surgical approach. About five years have passed from those operations, and results still are better than those obtained from earlier methods based on stabilisation of the sternum.

Spontaneous lesions in the sternums of growing rats.

Pathologic examination of sternums from young growing rats revealed a number of skeletal lesions involving both cartilage and bone elements. Degeneration or aseptic necrosis of the intersternebral cartilage was a frequent finding in most rats that were examined either at 130 or 180 days of age. Thickening of the sternal cortices and trabeculae containing prominent cement lines were less frequently occurring lesions in these sternums. These changes were absent in rats of 70 days of age. The etiology of the lesions is not understood, although several factors may be incriminated.

Primary osteomyelitis of the sternum due to Salmonella hirschfeldii.

The case of a 71 year-old man with primary osteomyelitis of the sternum caused by Salmonella hirschfeldii is reported. The diagnosis was confirmed by culture, the bony defect was curetted to remove all dead bone and the patient was successfully treated with 6 weeks of high-dose ampicillin (2 g q6h). The treatment is particularly important because inadequate treatment may result in death and overtreatment may cause deformity and instability of the chest wall. Primary osteomyelitis of the sternum is a rare entity and this is apparently the first such case to be reported in the English literature.

Bone scintigraphy in patients with breast cancer: malignant involvement of the sternum.

The cause of malignant involvement of the sternum is thought to be hematogeneous seeding as well as direct invasion from parasternal lymph node metastasis. The purpose of this study was to examine the pattern of metastasis to the sternum in patients with breast cancer and to evaluate the usefulness of postoperative irradiation for controlling sternal metastasis. Of 306 consecutive cases that were retrospectively reviewed, 16 (5.2%) were found to have sternal metastasis. Six cases had only the sternal lesion as the initial site of bone metastasis, and the others had a sternal lesion as part of multiple metastases. Three of 5 cases with a solitary sternal lesion were found by follow-up bone scintigraphy to have expanded to multiple bone metastases. The incidence of sternal metastases in patients with postoperative irradiation was significantly lower than that in nonirradiated patients (p < 0.001). Although the incidence of sternal involvement in patients with breast cancer was not low, it might be diminished by postoperative irradiation.

[Simple, complete, and comminuted fractures of the sternum. Analysis of 14 cases with osteosynthesis].

The authors report 14 cases of fractured sternum operated upon in thoracic surgery at United Hospital in Foggia. Most of the ostheosynthesis of the sternum were done with two Patellar set sutures. The follow-up revealed good stabilization of the thoracic cage and good alignment of the fractured site. Postoperative respiratory distress was never noted, neither was thoracotomy ever required.

The management of severe adherence of mediastinal structures to the sternum during cardiac reoperations.

The author's method for sternal re-entry in cases of extremely dense mediastinal adhesions is described. The anterior lamina and the spongiosa of the sternum is cut with an osteotome and the posterior lamina is divided using the Lebsche knife so as to leave the densely adhered patch of the posterior lamina on the underlying soft tissue. These bone fragments may be left in loco or, if the course of the operation requires it, they may be gently raised and peeled off. Removal of such a portion or portions of the posterior lamina does not appreciably weaken the sternum and safe sternal closure may be accomplished without difficulty.

[Reoperation of a pseudoaneurysm eroding the sternum under hypothermic arrest of the brain through left thoracotomy].

Reoperation of a pseudo aneurysm eroding the sternum was carried out in a 76-year-old female, using partial cardiopulmonary bypass and hypothermic circulatory arrest of the brain through left thoracotomy. The pulsating aneurysm protruding over the sternum was about 3.5 x 3.5 cm in size. Therefore, median sternotomy was thought to be risky. Cardiopulmonary bypass was established with left atrium and pulmonary artery for venous cannulation and femoral artery for arterial one. The patient was cooled and then the bypass discontinued. Previous patcth of the aneurysm was partially splitting and new patch was sutured. She awaked without cerebral injury of the operative day. This technique can be used as one of an alternative surgical method in the treatment of the distal aortic arch aneurysms.

Repair of ascending aortic aneurysm in a patient with fibrosarcoma over sternum.

The combination of an ascending aortic aneurysm and suprasternal soft tissue tumor is rarely reported in the literature. This case involves a 62-year-old man diagnosed with an ascending aortic aneurysm and a fibrosarcoma over the sternum that was successfully treated by surgery. The patient underwent an aortic replacement operation with a Dacron graft and a muscle flap transposition procedure to cover the defect over the sternum.

The heart is under the lower third of the sternum. Implications for external cardiac massage.

Current guidelines for cardiopulmonary resuscitation in children state that the heart lies under the midsternum in infancy and descends with age. To verify this statement, we studied 55 patients, aged 1 day to 19 years, including eight premature infants, during either routine chest x-ray films or right-sided heart angiography. Using a Cartesian coordinate system determined by radiopaque markers placed on the chest, and computer digitization, we located the center of each patient's cardiac silhouette and/or right ventricle. Using descriptive statistics, we found that the heart lay under the lower third of the sternum in all age groups. Analysis of variance indicated that there was no significant difference in this location between age groups. These results suggest that recommendations for external cardiac massage in infants and children may need to be revised.

Ectopia cordis and cleft sternum: evidence for mechanical teratogenesis following rupture of the chorion or yolk sac.

We present case material and a literature survey to document the association between ectopia cordis and band disruption anomalies. The occurrence of thoracic ectopia cordis with a cephalic-pointing cardiac apex suggests an arrest of cardiac descent at 3 weeks of development, consistent with our finding of ectopia cordis in a 28-day human embryo. Mechanical compression secondary to rupture of the chorion and/or yolk sac at 3 weeks of gestation would interfere with normal cardiac descent and compress the chest, yielding thoracic and pulmonary hypoplasia. Congenital heart defects associated with ectopia cordis may represent deformations secondary to mechanical distortion of the developing heart following early rupture of the chorion and/or yolk sac. As is illustrated by our clinical specimens, tethering of the heart to periumbilical structures by bands could yield thoracoabdominal ectopia cordis. The milder anomaly of cleft sternum, which is also associated with band disruptions, may occur later in development following rupture of the chorion, yolk sac, or amnion.

Primary Ewing's sarcoma of the sternum: a case report.

A 12 1/2-year-old female presented with Ewing's sarcoma of the manubrium sterni which extended into the anterior mediastinum. At presentation there was no evidence of metastatic disease. Her initial treatment consisted of radiation therapy and chemotherapy. The residual tumor was subsequently resected and the sternal defect was repaired with Marlex mesh. Postoperatively, she was maintained on chemotherapy consisting of BCNU, cyclophosphamide, and adriamycin. The adriamycin was discontinued after she developed sterile fibrinous pericarditis. She remains free of her disease two years after diagnosis. Although extremely rare, Ewing's does occur in the sternum and this area is amenable to wide local resection without severe functional disability.

A case of ovarian cancer with metastasis to the sternum and costae.

This report describes a case of ovarian cancer with metastases to the sternum and costae. Sternal and costal metastases from ovarian cancer are extremely rare. We introduce a case of sternal metastasis from ovarian cancer that occurred over 7 years after initial diagnosis which was successfully treated with local resection and systemic chemotherapy. Possible metastatic routes are discussed.

Radiology of postnatal skeletal development. II. The manubrium and sternum.

Thirty-six manubriosternal composites from skeletally immature cadavers were examined morphologically and radiographically. Sternebral ossification followed certain patterns. The manubrium (first sternebra) usually had one primary ossification center and one or two smaller centers. These usually were caudad to the major center (longitudinally bifid). The second sternebra invariably had only one ossification center. The third and fourth sternebrae had latitudinal (right-left) bifid ossification centers, undoubtedly a result of the original formation of the sternum from two longitudinal mesenchymal anlagen. Occasionally the fourth sternebra exhibited longitudinally bifid ossification. The usual pattern was ossification of four sternebrae, although a fifth was intermittently present. The xiphisternum (not a true sternebra) was infrequently ossified.

Osteoblastoma of the sternum.

Osteoblastoma has become a well defined bone tumor since its first description by Jaffe and Mayer in 1932. This tumor was considered to occur in almost any bone of the skeleton. Only one previous case of sternal osteoblastoma was described in the literature. Herein we report, as far as we know, the second reported case of osteoblastoma in the sternum, as an isolated tumor.
