A man with a quiescent Reiter's disease presented with abrupt upper chest pain. This symptom resulted from a septic arthritis of the manubriosternal joint due to staphylococcus aureus cultured from the synovial fluid.
This report describes the case history of two patients who showed a hyperactive midsternal area on bone scintigraphy due to a persistent sternal synchondrosis. Whereas this anatomical variant is diagnosed infrequently, midsternal hotspots can sometimes be related to arthrotic degeneration of these extra joint spaces. In the differential diagnosis of midsternal hotspots on bone scintigraphy, persistent sternum synchondroses should be considered.

We describe the imaging procedures for the diagnosis of manubriosternal joint arthritis in a 64 years old man with psoriatic arthritis. Involvement of the manubriosternal joint (synchondrosis sternalis) in psoriatic arthritis is a rare manifestation. The findings of bone-scintigraphy, conventional radiography and arthrosonography of the manubriosternal joint arthritis are compared and discussed.
The anterior aspect of the upper thoracic spine is a difficult region to approach in spinal surgery. Many vital structures including osseus, articular, vascular and nervous ones hinder the exposure. With increasing frequency, spine surgeons are being asked to provide decompression and stabilization in patients with spinal tumors. The traditional exposure is between the esophagus and trachea medially and the left common carotid or the brachiocephalic artery (BCA) laterally, and the disadvantages were that the ligation and section of the left innominate vein is proposed to reach T4 and the injury of the thoracic duct could occur. The right space of the BCA or the ascending aorta (AA) (the exposure between the right brachiocephalic vein and the BCA or between the AA and superior caval vein) is recommended in exposing the upper thoracic vertebrae; this new space is technically feasible; the exposure is sufficient for vertebral body resection and reconstruction and fixation. Twenty-eight patients with upper thoracic spine tumors underwent surgery by the use of this new space between June 2000 and October 2005. A strut graft was fixed anteriorly after decompression of the spinal cord. Levels C7-T5 can be well exposed through this new space, allowing complete vertebral body removal at level T1-T4. After body removal, the posterior longitudinal ligament is well exposed, allowing complete release of the spinal cord. Curettage was performed in one case of aneurysmal bone cyst and three cases of bone giant cell tumors. For other tumors, vertebrectomies or sagittal resections were performed. Four patients underwent surgery by a combination of anterior and posterior approach.
Symptomatic manubriosternal arthritis, occasionally encountered with spondyloarthropathies, may not be adequately controlled by systemic therapy. Local corticosteroid injections make a potential contribution to symptomatic management. Three patients with acute inflammation of the joint as documented by MRI and fluoroscopy-guided therapy are presented. Topical treatment with triamcinolone acetonide (40 mg) was well tolerated and induced rapid and complete relief of pain for between 3 weeks and 3 months. In spite of the clinical improvement, the signs of inflammation in MRI did not decrease. Local steroid application seems to be an underused therapeutic modality in managing rheumatic involvement of the anterior chest wall.
We present a 40-year-old woman complaining of worsening chest pain. She was previously treated with a prolonged course of antibiotics for suspected sternal osteomyelitis. Radiological investigations were suggestive of ongoing inflammation within the manubriosternal joint. Formal surgical debridement yielded evidence corroborating the diagnosis although microbiological samples were negative. Prolonged empirical treatment with intravenous antibiotics leads to a complete resolution of symptoms. Primary culture-negative manubriosternal septic arthritis is rare, and suboptimal treatment, particularly if confused with other conditions such as synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) syndrome, compounds its considerable morbidity.

The shape of the tympanic membrane is fairly complex and seems to be of significant importance in the coupling of the acoustic sound pressure in the external ear canal to the motion of the middle ear ossicles. A moiré shift interferometer was used to measure with great precision the shape of the external surface of human tympanic membrane. The dense matrix of z(x,y) values thus obtained is used to calculate different geometrical parameters (area, curvature, ...). We show further how the same data can be used to specify exactly the shape of the tympanic membrane in a mathematical finite-element model of the middle ear.
Deceleration injuries combined with hyperflexion of the torso as seen in motor vehicle accidents can result in combination of sternal and spinal fractures. This type of injury is associated with abnormalities of the soft tissue structures of the thorax. This publication reviews a case report of a deceleration injury and emphasizes the imaging modalities necessary to evaluate this constellation of abnormalities.
OBJECTIVE: In a prospective study, the effect of thymectomy on the pulmonary status of 50 consecutive patients with myasthenia gravis was evaluated over a time range of 4 years in the Chest and Chest surgery departments in the Cairo University Clinics and Thoracic Surgery Department of the Evangelisches Krankenhaus Duisburg-Nord. METHODS: The patients were divided into two groups: Group I included 26 patients who underwent thymectomy through median sternotomy. The mean age of the patients in this group was 24.8+/-10.5 (5-41) years. They were 19 females and seven males. Thirteen of the patients were in Myasthenia Gravis Foundation of America (MGFA) class IIa, and 12 were in class IIb, and one was in class IIIa. Group II included 24 patients who underwent thymectomy through manubriotomy. The mean age of the patients in this group was 25.2+/-9.2 (12-41) years. They were 13 females and 11 males. Eight of the patients were in MGFA class 2a, 14 were in class IIb, and two were in class IIIa. RESULTS: When compared to group I in which postoperative ventilation was required in 15.4% of patients, postoperative ventilation was not necessary in patients of group II with a statistically significant difference (P=0.04). The mean duration of stay in the intensive care unit was 111.4h in group II, and 169.7h in group I (P=0.03). The peak inspiratory flow rate and the forced vital capacity were also statistically significantly better in group II. There was no mortality in both groups, and the morbidity was higher in the median sternotomy group. CONCLUSION: Thymectomy through a manubriotomy, which allows extensive removal of ectopic thymic tissue in addition to the thymus through a less invasive approach than a full median sternotomy, is associated with a significantly smoother postoperative course and less pulmonary complications, when compared with thymectomy through a full median sternotomy.

Osteoarthritis of the manubriosternal joint is rare. The diagnosis is not easy to make, and more serious causes of chest pain have to be ruled out first. We report one case that was treated with arthrodesis of the manubriosternal joint using double locking screw compression plating (LCP) with excellent results. Pre-operative CT-scan images with 3D reconstruction were used to measure the screw length and the drill stop depth. In this case report, we have shown that arthrodesis can be an effective way of treating osteoarthritis of the manubriosternal joint, when other measures fail. Furthermore, the use of a locking compression plate with appropriate and careful pre-operative planning affords a safe surgical technique, rapid pain relief and ultimately sound and asymptomatic union of the joint.
BACKGROUND: Although patients with pectus carinatum (PC) often experience moderate to severe symptoms, there are sparse published data about the indications for correction, the newer techniques of surgical repair, and the results. This study reviews clinical experience with new, less extensive, open operative techniques for repair of PC. STUDY DESIGN: Since 1970, 154 patients (119 men and 35 women) with symptomatic PC (mean severity index 1.76) underwent correction at the UCLA Medical Center using modifications of the Ravitch repair. The last 60 consecutive patients had a less extensive open repair with resection of only small chips of cartilage medially and laterally, and suture reattachment of the remaining costal cartilages to the corrected sternum and ribs. For patients with chondromanubrial protrusion, two or three sternal osteotomies were used, and for those with concomitant lower sternal depression, a lower sternal wedge osteotomy was used. For most patients, a temporary support bar anterior to the sternum and cartilages was used for 6 months. RESULTS: Each of the 154 patients with reduced endurance or dyspnea with mild exercise experienced marked improvement within 6 months. There were no major recurrent deformities; six patients underwent minor surgical revision of localized persistent costal cartilage protrusion or depression. Postoperative complications in the last 60 patients were minor and less frequent, pain was less severe, hospitalization was shorter (mean 2.5 days), and postoperative results were better than when more extensive repairs were used in previous years. With a mean overall followup of 7.9 years, more than 97% of all patients experienced a very good or excellent result. CONCLUSIONS: New, less extensive, open techniques for repair of PC have low morbidity, short hospital stay, and very good physiologic and cosmetic results.
Claviculectomy has been described for primary or metastatic tumors of the clavicle. In 11 patients, claviculectomy was used as a technical expedient for the exposure and en bloc resection of large, underlying nodal metastases from melanoma (7 patients) and soft tissue tumors (4 patients). There were no wound complications. Three patients developed moderate edema of the arm. There was little limitation at the shoulder, and the use of the upper extremity has been essentially normal. Claviculectomy is well tolerated, provides good exposure of the underlying neurovascular structures, and, in some patients, provides a method of limb salvage for underlying tumors in preference to forequarter amputation.
The transmanubrial approach allows excellent unilateral exposure of the thoracic outlet. However, selected patients may require a bilateral cervicomediastinal exposure to completely resect the neoplasm. We report the use of a "double" transmanubrial approach for the resection of a giant mediastinal mass requiring bilateral vascular dissection and superior vena cava system resection and replacement.
The transclavicular approach improved the treatment of apical chest tumors. However, removing the internal half of the clavicle and sectioning its muscular insertions led to serious postoperative alterations. We propose a transmanubrial approach, through a manubrial L-shaped transection and first costal cartilage resection, which allows retraction of an osteomuscular flap including but sparing the clavicle and all its muscular insertions. The elevation of the osteomuscular flap affords excellent access to the subclavicular region with safe control and resection of neurovascular outlet structures during the resection of apical chest tumors. Shoulder articulations and stability of the scapular girdle are respected, thus avoiding functional and cosmetic consequences of clavicle resection.
