Congenital pseudarthrosis of the clavicle.

This is a report of 5 cases of congenital pseudarthrosis of the clavicle, a rare disorder of the shoulder girdle. Little more than 100 cases have been reported in the literature; 3 of our 5 cases represent a very rare form of left side involvement with dextrocardia. The pseudarthrosis mass generally protrudes under the skin and may need surgical correction. When unilateral, there is marked and unexplained predominance for the right side. Three cases required no treatment; 2 were successfully treated by excision of the bone ends, bone grafting and internal fixation.

[Treatment of thoracic outlet syndrome following fracture of the clavicle with resection of the 1st rib (author's transl)].

The resection of the first rib with a transaxillary approach has been used in the operative treatment of this condition. This approach is though to have more advantages over the anterior (supraclavicular) or posterior (parascapular) ones. The segment resection of the middle third of clavicle would not seem to be justified in these cases. A case is reported in details, where the results support their concept.

[Solitary plasmacytoma of the scapula and clavicle].

A 59 year old female patient with a large solitary medullary plasmocytoma of two years duration of the right scapula and clavicle is presented. The patient refused operation and received telecobalt radiation therapy. The palpable swelling and pain disappeared. Bone marrow puncture, blood and urine analyses were quite normal. An individualized therapeutic procedure is recommended for such cases.

[Aneurysmal cyst of the clavicle : an uncommon lesion and a difficult diagnosis (author's transl)].

The authors describe a case of anevrysmal cyst of the clavicle seen in a five-year-old girl. Both clinical and radiological diagnosis proved impossible. Complementary investigations did not settle the question. surgical excision was decided on. In spite of an unfavorable macroscopic aspect, histological examination determined the nature of the tumor. The authors emphasize the great value of resorting to all branches of medical investigation when dealing with bone tumors. Before affirming a good prognosis, or, on the opposite, suggesting extensive and mutilating surgery, the utmost caution is required.

Hyperostosis of the clavicle and ossification of the costoclavicular ligament in association with ankylosing spondylitis.

A patient with ossification of the ligaments of the entire vertebral column has shoulder difficulties due to ossification of the right costoclavicular ligament. The speculation is that the sclerotic changes in the clavicle were caused by the same inflammatory process that has involved the ligaments of the vertebral column and of the sacroiliac joints. In some cases reported in the literature, although not in ours, vascular structures in the costoclavicular space were involved, resulting in venous obstruction or phlebitis. The patient's therapy currently consists of rehabilitation exercises. Nonsteroidal antiinflammatory medication was prescribed in the past without any marked benefit.

Retrosternal dislocation of the clavicle. Observations on three cases.

The writers report three cases of retrosternal dislocation of the clavicle which exemplify the three fundamental anatomical variants and the consequent different therapeutic approach. A review of the literature indicates that this condition is extremely rare, although it may sometimes be related to severe and even fatal complications.

Osteomyelitis of the clavicle after Swan-Ganz catheterization.

Osteomyelitis of the clavicle is an uncommon complication of Swan-Ganz catheterization. The diagnosis should be suspected when the clinical features of fever and sterno-clavicular pain are present. Traditional roentgenograms may be falsely normal early in the disease. Radioactive isotope scanning may be helpful in establishing the diagnosis sooner, followed by tomography or computed tomography to better define the abnormality. Therapy should include long-term parenteral antibiotics and possible surgical removal.

Acromioclavicular dislocations: treatment by transfer of the conjoined tendon and distal end of the coracoid process to the clavicle.

A retrospective study of 23 acute and 6 chronic acromioclavicular dislocations treated by surgical transfer of the distal 1/2 inch of the coracoid process with the attached conjoined tendon of the coracobrachialis and short head of the biceps to the clavicle revealed 14 excellent, 14 good and one fair result. Results were determined according to symptoms, range of motion at the shoulder and elbow, strength, anatomic reduction, and return to previous activities. Although most patients with this injury are treated conservatively, this procedure is reserved for the athlete or manual laborer below age 45 years, especially with involvement of the dominant-extremity. The 29 cases were evaluated 20--108 months following surgery. Thirteen additional cases with less than 18 month follow-up have also been good or excellent. Weakness and pain have not been as pronounced following this procedure in vigorous individuals as have been noted after conservative treatment. Few postoperative complications developed, and early return to competitive athletics was possible.

[Congenital pseudarthrosis of the clavicle: roentgenographic appearance and discussion of the aetiological and pathogenetical theories [author's transl].

The authors briefly reviewed the anatomic and radiological pattern of the congenital pseudarthrosis of the clavicle, with the main aetiological and pathogenetical theories. They also report their personal experience about 2 patients, stressing the peculiarity of this affection compared with others similar in their radiological pattern. They underline the coexistence, in one of the two cases, of the Ehlers-Danlos syndrome, suggesting a single vascular aetiology and pathogenesis.

Pathologic fracture of the clavicle caused by arteriovenous malformation.

An anusual pathologic fracture of clavicle was caused in a 48-year-old woman by an arteriovenous malformation. The lesion radiologically mimicked a neoplastic process. Arteriography disclosed the vascular cause. Treatment was achieved by interrupting the feeding vessels and resecting the involved bony segment.

[Supraclavicular nerves perforating the clavicle. Study of 10 cases].

The present study concerns a report on the observations of supraclavicular nerves with abnormal passage though one or several intraclavicular bone canals. The explanation of the formation of interclavicular canals is found by the normal development of the clavicle. In most of the cases the bone canals are situated in the central part of the clavicule and rarely at the acromial end. The canals are either superficial or deep. Often bone bridges are formed. The bone canals and the supraclavicular nerves are barely visible on X-ray photographs. Polarising microscope analysis shows that the intraclavicular canals do not have the structure of the perforating canals of Volkmann. It can be deduced that the supraclavicular nerves have not pierced the bone substance already formed but, that they have been enclosed during later bone formation. Of the 254 cases studied (189 male and 65 female) the incidence of the described abnormality was 4% (10 cases) of which 3% were male.

Congenital pseudarthrosis of the clavicle. Histologic examination for the etiology of the disease.

The etiology of congenital pseudarthrosis of the clavicle remains obscure. The authors treated a 5-year-old boy with this rare disease. Clinical history and radiographs confirmed the diagnosis. Surgical treatment of resection of the pseudarthrosis, autologous bone graft, and internal fixation with a small AO plate led to successful bone union. Histologic analysis of the pseudarthrosis showed that there were cartilaginous caps on the proximal and distal bony ends. The appearance of the cartilaginous caps were equivalent to that of developing physes. They were adding new bone to the bony ends, which also was confirmed by preoperative tetracycline labeling. These observations support the hypothesis that the pseudarthrosis is caused by failure of 2 ossification centers to fuse, as was previously proposed by others.

[Osteochondroma of the clavicle and pain syndrome of the shoulder. Apropos of a case. Review of the literature].

INTRODUCTION: Osteochondroma, a frequent benign tumor of the bone, is in most cases asymptomatic. Localization in the clavicle is extremely rare. The authors report an isolated case occurring in the coraco-clavicular area responsible for a painful shoulder syndrome evoking rotator cuff tendinitis. METHODS: A 47 years female patient consulted for painful shoulder syndrome. Pain occurred following an effort and at night. On clinical examination, the area around the coracoid process was tender as was the supraspinatus fossa. Passive anterior elevation of the shoulder was limited to 150 degrees. She had a positive Job's sign as well as a painful << Gross armtest >>. Initial Radiological assessment showed no anomalies. Arthrographic CT scan revealed an expansive process compatible with osteochondroma. The lesion was in contact with the supraspinatus muscles and the coracoid process. Extraperiosteal resection was performed through a delto-pectoral approach. Recovery of a painless mobile joint was rapid. DISCUSSION: Clavicular embryology is not yet well understood. The appearance of an exostosis at this localization seems to confirm that the clavicular cartilage behaves as an epiphyseal bone plate. The exostosis, which has a congenital origin, can appear, when it reaches a certain size or when it mechanically interferes with surrounding muscles and tendons. In our observation, the lesion led to irritation of the supraspinatus muscle leading to tendinitis. Diagnosis is usually made on standard roentgenographic evaluation. CT scan and MRI show a cartilaginous coating which should not exceed 10 mm in the case of a benign tumor. There exists a possibility of sarcomatous degeneration, but this is rare on the peripheral skeleton. Treatment should be performed by complete extraperiosteal resection of the exostosis along with its perichondral cover. CONCLUSION: Clavicular localization of an osteochondroma is very rare. This case report illustrates the possibility of a painful shoulder syndrome associated with this lesion. This report also seems to suggest the hypothesis that the cartilage at this level behaves as an epiphyseal bone plate.

The incidence of fractures of the clavicle.

The age- and gender-specific incidences were calculated in 2035 cases of fracture of the clavicle. The fractures were classified in three groups according to the Allman system. Each group was further divided into undisplaced and displaced fracture subgroups, with an extra subgroup of comminuted midclavicular fractures in Group I. Seventy-six percent of the fractures were classified as Allman Group I. The median age in this group was 13 years. There were significant differences in age- and gender-specific incidence between the undisplaced, displaced, and comminuted fracture subgroups. Twenty-one percent were classified as Allman Group II. The median age of the patients was 47 years, and there was no difference in age between the undisplaced and displaced fracture subgroups. Three percent were classified as Allman Group III, and the median age of the patients in this group was 59 years. All three groups were characterized by a significant preponderance of men, and there was a significant increase in the incidence of clavicular fracture, both overall and sports-related, between 1952 and 1987.
