a 5-day-old female holstein calf was necropsied because of lethargy, recumbency and anorexia. at necropsy, multiple gross defects were evident in several organs, including unclosed sutures of skull bones, asymmetrical orbits, doming of the skull bones, hydrocephalus, hydranencephaly, cleft palate, brachygnathia, ventricular septal defect, mitral valve dysplasia and rudimentary lungs. on microsc...

A case of congenital pseudarthrosis of the clavicle is presented. Congenital pseudarthrosis of the clavicle is an entity that has rarely been recorded in the radiological literature. The etiology of the condition remains obscure. The radiographic appearance is characteristic.

The purpose of this paper is to describe a monarticular, non-infective subacute arthritis of the sterno-clavicular joint which occurs in middle-aged women. The clinical features are so typical and the course is so predictable that this condition can be considered a specific entity. This report is based on twelve patients. Seven were studied by the author throughout their illness; the other five...

We describe the case of a 47 year old patient with proven primary IgA nephropathy who presented with osteomyelitis of the medial end of the right clavicle. The patient was not on immunosuppressive medications. He underwent aspiration curettage and CT scan of the clavicle which yielded pus that grew Pseudomonas aeruginosa. Following treatment with appropriate antibiotic therapy the patient prese...

Plasmacytoma is a localized collection of malignant plasma cells. The disease is divided into Solitary plasmacytoma of the bone (SPB) and extramedullary plasmacytoma (EMP) which are both distinct entity. SPB usually occur in the bones characteristically affected in multiple myeloma and EMP was most frequently located in the oronasopharynx and paranasal sinuses, with a 15-30% incidence of region...

Clavicle fractures are frequent injuries in athletes and midshaft clavicle fractures in particular are well-known injuries in Ironman triathletes. In 2000, Auzou et al. described the mechanism leading to an isolated truncular paralysis of the musculocutaneous nerve after a shoulder trauma. It is well-known that nerve palsies can lead to an atrophy of the associated muscle if they persist for mo...

Endometrial adenocarcinoma metastasizing to bones is rare, and isolated metastasis to clavicle is even more uncommon. We report a case of a 60-year-old woman diagnosed with endometrial adenocarcinoma found to have isolated metastasis to the clavicle during adjuvant radiotherapy. Following radiation therapy to the clavicle, patient was started on injection zoledronic acid. She was then planned f...

The differential diagnosis of a fractured clavicle includes acute traumatic fracture, stress fracture, pathologic fracture secondary to radiation exposure, neoplasm, infection, or metabolic bone disease, and fracture-like conditions such as infection and bony dysplasias. An appropriate workup should identify most of these underlying conditions. We report a case of concurrent bilateral nontrauma...

ABSTRACT We present here a technique of fracture stabilization using the Tightrope procedure in a patient with a widely displaced Neer type IIB distal clavicle fracture. The Tightrope system, typically used for stabilization of acromioclavicular joint dislocation, has not been widely described for distal clavicle fractures. The patient achieved satisfactory results after surgery; we feel that t...

Pain and impaired function in the shoulder can result from a variety of conditions. Dysplasias of the shoulder girdle are usually asymptomatic; previous literature reports on shoulder malformation have focused on glenoid dysplasia or complete agenesis of the clavicle. We report the case of an 11 year old patient with severe shoulder pain after strenuous physical exercise. Physical inspection sh...
