Diagnosis of bone and joint infection by leucocyte scintigraphy. A comparative study with 99mTc-HMPAO-labelled leucocytes, 99mTc-labelled antigranulocyte antibodies and 99mTc-labelled nanocolloid.
Fifty-five patients with 60 suspected infections of bones or joints were studied with 99mTc-hexamethylpropyleneaminooxine- (HMPAO-) labelled leucocytes and 99mTc-labelled antigranulocyte antibodies, in part supplemented with 99mTc-labelled nanocolloid. The findings using the different procedures were in good agreement. ⋯ Spondylitis usually shows as non-specific cold lesions. A subtraction technique with computer assisted analysis of HMPAO and nanocolloid scans provides a more precise diagnosis of this condition.

Effect of direct-current stimulation on the growth plate. In vivo study with rabbits.
Electrical stimulation of 8 microA direct current was applied to the femoral distal growth plate of young rabbits for periods of 1, 2, and 3 weeks to examine the effect on bone growth. The results were analyzed using X-ray measurement, histological observation including tetracycline labeling, and glycosaminoglycans analysis. No obvious differences between the stimulated side and the control side were observed in the morphological and biochemical studies, but characteristic thickening of the growth plate caused by the accumulation of hypertrophic cells was found in the group stimulated for 2 weeks. Electricity affects the cell behavior of the growth plate, but it is necessary to find more appropriate conditions to stimulate obvious bone growth.

Aseptic osteonecrosis of the humeral trochlea (Hegemann's disease).
A differential diagnosis of diseases affecting the elbow joint in children should also give due consideration to osteonecroses. They are very rare in the context of the humeral trochlea, the case with which we are concerned being one of a total of 15. In the light of this syndrome's relative rarity, we will report on the case of a 7-year-old boy. This is also the first time that a MR image of Hegemann's disease has been shown.

Review Case ReportsBrachial artery injury in closed elbow dislocation. Case report and review of literature.
A case of elbow dislocation with injury to the brachial artery is described. The rarity of the complication makes the treatment controversial. Conservative treatment should be the first line of management of this vascular complication.

To realize the new concept of biological internal fixation the limited contact dynamic compression plate was developed. It minimizes vascular damage to the plated bone segment. It should lead to a more versatile and efficient application of internal fixation using plates.
