We present a case of subperiosteal giant-cell reparative granuloma followed over six years showing the complete evolution from the early phase of subperiosteal haematoma to the end stage of an ossified haematoma. Such lesions, although they are histologically similar to true giant-cell tumours, can be distinguished by the patients' age, their location on the diaphysis, and by their radiological...

Fibrous dysplasia is a common benign skeletal lesion that may involve a single bone or multiple bones. Although fibrous dysplasia can affect any bone, monostotic fibrous dysplasia of the long bone typically occurs in the diaphysis or metaphysis. We report a very rare case of monostotic fibrous dysplasia involving the epiphysis of the distal femur in a young man.

The effects of clodronate administered p.o. on bone mineral density (BMD), bone geometry and strength of bone were investigated in 6-month-old ovariectomized rats. Sixty Sprague-Dawley rats were randomized into four groups. Three groups were ovariectomized (OVX) and one group was sham-operated (SHAM). The OVX groups were given p.o. either clodronate (100 mg/kg/d or 500 mg/kg/d) or a vehicle. Th...

OBJECTIVE To analyze the validity of measurements of medial rotation (MR) of the shoulder, using vertebral levels, according to the variation in the position of the humeral diaphysis, and to test the bi-goniometer as a new measuring instrument. METHODS 140 shoulders (70 patients) were prospectively evaluated in cases presenting unilateral shoulder MR limitation. The vertebral level was evalua...
