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.

Sclerosis and hyperostosis of the manubrium sterni.

Seven females and one male with almost identical sclerotic and hyperostotic changes of the manubrium sterni are reported. The clinical course was prolonged and characterized by intermittent periods of exacerbation followed by improvement. Malignancies, bacterial inflammatory processes, and Paget disease, which were first suspected, could be excluded. Pustulosis-palmoplantaris was present in four patients and one had psoriasis vulgaris. None of the patients had sacroiliitis or peripheral joint changes, but the three youngest patients had sclerotic changes of other bones, including the lumbar spine, the pubic bone, and the clavicle. This may indicate that this is an adult disease analogous to "chronic recurrent multifocal osteomyelitis", a disease mainly present in children and adolescents.

Tassier cleft no 30 (median cleft from lower lip to manubrium).

One-year-old female presented with cleft of lower lip, mandible, fissured tongue, absent hyoid bone, cleft of manubrium sterni, later is detected clinically by suprasternal bulge at suprasternal region while crying. It is radiologically detected by wide apart medial end of clavicle. This is extremely rare anomaly known as Tassier Cleft no 30.

Radiation dose by spiral CT and conventional tomography of the sternoclavicular joints and the manubrium sterni.

UNLABELLED: OBJECTIVE DESIGN AND PATIENTS: Conventional frontal tomography of the sternum has to some extent been replaced by spiral computed tomography (CT). The objective of this study was to analyse this change of procedure in terms of dosimetry by measurement of the radiation dose to individual organs using an anthropomorphic Rando Alderson phantom. RESULTS: The total effective radiation dose in examination of the sternoclavicular joints and the manubrium sterni was found to be lower using spiral CT than conventional tomography, the values being 0.6 and 0.8 mSv, respectively. CONCLUSION: As spiral CT is diagnostically comparable and in some respects superior to tomography, its use is recommended for studies of the sternum.

Manubrium-sparing sternotomy and off-pump coronary artery bypass grafting in patients with tracheal stoma.

The presence of a tracheal stoma in patients with previous total laryngectomy who require cardiac operations is associated with an increased risk of wound complications and tracheal injuries when a full sternotomy is used. The aim of this report is to describe a technique of manubrium-sparing sternotomy, which can be used in patients undergoing coronary artery bypass grafting without cardiopulmonary bypass.

Median cleft of the lower lip, mandible and manubrium. A case report.

There is a wide variation in the severity of median clefts of the lower lip and mandible. We report a severe case demonstrating clefts of the lower lip and mandible together with lack of supporting structures in the neck and upper sternum. Since a case with a cleft of the manubrium sterni is very rare, the literature is reviewed and discussed.

An anterior approach to the cervicothoracic junction of the spine (modified osteotomy of manubrium sterni and clavicle).

Standard anterior approaches to the cervicothoracic junction of the spine provide inadequate exposure. For this reason, various techniques of exposure are developed. One of these is Sundaresan's technique in which a part of the manubrium sterni and medial clavicle is resected. This technique provides good visibility and working area at the lesion level but causes a significant bony defect. We modified Sundaresan's technique and did not damage the sternoclavicular joint. After decompression and fusion was completed, the osteotomized segment was replanted. We performed this technique in a case of Pott's disease and had no problem with union at the osteotomy sites.

Chondrosarcoma of the manubrium. Resection and reconstruction with pectoralis major muscle.

Chondrosarcomas of the sternum are best treated by resection with tumor-free margins. Reconstruction of the manubrium and superior aspect of the sternum is one of the most difficult challenges for the reconstructive surgeon. In the past, most of the structural stability following resection of this area has depended on the formation of dense fibrous tissue and scar. We presented a case of reconstruction of the bony defect with autogenous bone grafting in conjunction with transposition of the pectoralis major muscle for increased protection and stability of the chest wall as well as for nourishment for the bone graft.

[Case of aneurysmal bone cyst in sternal manubrium].

A 27-year-old female who suffered from aneurysmal bone cyst in sternal manubrium, which is histologically confirmed, underwent sternal manubriumectomy. Tumor was totally resected. Manubrial defect was replaced with two metal plates, which joined both stumps of the second ribs and both sternal ends of clavicles, respectively, and wide Marlex mesh. Using non-absorbable sutures, two metal plates were fixed to the mesh, and the mesh was also secured to surrounding structures, to hold the normal function of thorax and shoulder joints.

Manubrium sterni stress fracture: an unusual complication of non-contact sport.

Tremendous force is usually required to cause sternal fractures. Normally this is caused either by a direct blow to the chest or by an indirect injury from hyperflexion of the torso. A case is presented of a fracture of the manubrium sterni in a young man as a complication of body building exercises-a non-contact sport. It appears that this has not been reported before.

[Channel fixation of a fascial graft to the manubrium mallei in tympanoplasty].

Long-term results of tympanoplasty with channel fixation of the fascial graft to the manubrium mallei (MM) is described. For better contact of the fascia with the malleus, a blind channel in the graft is created and the graft is put on the MM. The above operation was performed in 86 patients. The results were compared to those of 51 tympanoplasties when the MM was passed through the hole created in the graft. Better late results were obtained in tympanoplasty with channel fixation. The tympanic membrane healing rate was 92%, no lateralization occurred. The average pure air conduction threshold at frequencies 0.5-2 kHz has become 22.1 +/- 1.64 dB (before operation 37.7 +/- 1.60 dB; p < 0.001), average bone conduction threshold 11.8 +/- 1.21 dB (before operation 13.7 +/- 1.25 dB; p > 0.05) and air-bone gap was 10.4 +/- 0.9 dB.

Heterodyne interferometer measurements of the frequency response of the manubrium tip in cat.

A heterodyne interferometer proved to be a very accurate tool to measure amplitude and phase of the malleus response during acoustical stimulation. It was shown that to obtain equal accuracy in the acoustical pressure measurements, pressure response must be remeasured at short time intervals. At frequencies above 4 kHz various gross resonances are apparent on the frequency response curves. The resonances are, depending on the animal, more or less pronounced. As a result of the improved accuracy changes of the malleus vibration response with time could clearly be discriminated. These changes can be related to shifts in frequency of the position of these resonances. Comparison of experimental frequency response and lumped parameter model predictions from literature shows that these resonances are not present in the model responses.
