Calibration of the NPL secondary standard radionuclide calibrator for 192Ir brachytherapy sources.

Safe and effective treatment with brachytherapy sources requires an accurate knowledge of the local tissue absorbed dose rate derived from the source reference air kerma rate. It is desirable that these air kerma rate measurements be traceable to national standards. The NPL has embarked on a programme that will enable the user to assay brachytherapy sources in a convenient manner prior to treatment. Calibration figures have been derived for the NPL secondary standard radionuclide calibrator for 192Ir brachytherapy sources manufactured by Amersham International plc. The calibration figures enable the user to accurately estimate the reference air kerma rate and activity of such sources by measuring the ionization chamber response. Calibration figures for other brachytherapy sources are also being derived.

Intramedullary supracondylar nailing of femoral fractures. A preliminary report of the GSH supracondylar nail.

From 1987 through 1990, 34 acute supracondylar femoral fractures in 33 patients were treated with an interlocking closed-section intramedullary nail inserted retrograde into the femur through the intercondylar notch. Follow-up data of at least five months were available for 25 of these fractures. The patients suffered injuries more extensive than comparable patients reported in the literature. All fractures healed clinically and radiographically. The average arc motion at the most recent evaluation was 100 degrees. The average operative time was 156 minutes and the average estimated blood loss was 224 ml. Complications related to this treatment were successfully resolved. The genucephalic nail is a good treatment for supracondylar femoral fractures.
