[Histomorphological studies on the development of the radial condyle fracture of the humerus in the growth years].

The dislocation of the lateral humeral condyle represents a typical fracture in childhood. Possible mechanisms of the traumatic displacement of the lateral humeral condyle got investigated by several publishers recently. Our examinations were concerned with the microarchitecture of the growing distal humeral cartilage. Here we discovered a bundle of collagenous fibers reaching in an angle of 15 to 30 degrees from the capitulum to the trochlea. The described fracture follows this collagenous bundle as we could demonstrate. It is evident that the microarchitecture of the cartilage paves the way for the dislocation of the lateral humeral condyle.

Ewing's sarcoma of the humerus mimicking fibrous dysplasia on imaging and biological behavior.

We present the case of a 12-year-old girl who presented with a pathological fracture through a benign-appearing osteolytic lesion that was presumed to represent fibrous dysplasia. The fracture healed, and over the next 2.5 years there was further refracturing and healing with progressive osteolysis. A biopsy was performed and revealed Ewing's sarcoma. The disease was locally controlled by neoadjuvant chemotherapy and radiation therapy. The patient is disease free with excellent function 6 years following the discovery of the lesion. We illustrate and discuss the sequence of events.

Discrete synchronous multifocal osteoid osteoma of the humerus.

A 24-year-old patient is described who had a 4-year history of pain in the right upper arm, with distinct night pain, that responded to salicylates. From the findings on conventional radiography, bone scintigraphy and MRI a multifocal osteoid osteoma was suspected, with one focus in the cancellous region of the greater tuberosity and a second cortical focus at the proximal humeral diaphysis. The resection "en bloc" of both tumors and histological examination confirmed the diagnosis. The patient was painfree after the curative resection of the two osteoid osteomas. Osteoid osteoma is a frequently found benign bone tumor, accounting for approximately 11% of cases. In rare cases a multicentric occurrence has been described. A possible occurrence of more than one osteoid osteoma in a single bone, not verified histologically, has been reported only three times in the literature. In patients with scintigraphic and radiographic findings of two foci, discrete synchronous multifocal osteoid osteomas should be suspected.

Severe toxic osteoblastoma of the humerus associated with diffuse periostitis of multiple bones.

Toxic osteoblastoma is a rare variant of an uncommon primary bone tumour that has been described only once before in the world medical literature. It is characterised by systemic features including fever, weight loss and a striking diffuse periostitis in association with an osteoblastoma, resulting in delayed diagnosis. Early recognition of this condition could prevent inappropriate therapies and reduce morbidity.

Tossed on the horn of humerus: a legal case report.

Radiological cases constituted 2% of the total number of legal cases in Sweden during 1996. The young man in this report accused a radiologist of having missed a fracture 7 years earlier based on a new radiology examination and report. In reality the latter report was incorrect and the patient had a rare exostosis that explained the clinical signs and symptoms. The alleged fracture was an epiphyseal line to a non-unified ossification centre at the tip of the unique exostosis.

A rare case of Salmonella osteomyelitis in the humerus as a differential diagnosis to a malignant bone tumor.

Salmonella osteomyelitis without predisposing factors is seldom seen and thus difficult to diagnose. We report on a 14-year-old healthy boy with Salmonella osteomyelitis which occurred 2 years after trauma. Radical operative debridement is recommended. Intravenous ciprofloxacin has proved to be effective because of good tissue penetration and sensitivity towards Salmonella.
