RESUMO
We studied 43 patients with ipsilateral femoral shaft and femoral neck fractures who had dynamic hip screw fixation alone or in combincation with dynamic compression plate. All patients except two were diagnosed early; 37 patients had other associated injuries. There were 41 males and two females. The follow-up ranged from eight months to four years (mean 2-1/2 years). Six patients were lost to follow-up. Fracture of the neck of the femur healed in all 37 patients. Four patients had delayed union and two patients developed nonunion of the shaft of the femur. The aim of this paper is to show our experience and results using one technique for the treatment of such fractures.
RESUMO
The characteristics of laser lithotripsy of biliary calculi are compared for a flashlamp pumped dye laser (lambda = 640 nm) and a Cr:Tm:Ho-YAG laser (lambda = 2.1 microns). Data on fragmentation efficiency with respect to laser power and pulse repetition rate are presented for different types of stones. It is shown that both lasers can produce effective stone fragmentation. The laser power required for efficient fragmentation characteristics is significantly less for the visible wavelength laser. However, the problems associated with damage to the fiber tips of the delivery system during operation were found to be less with the near infrared wavelength. The laser power for efficient fragmentation with the dye laser varies significantly for different types of stones while the power for efficient fragmentation with the holmium laser is the same for all stones.
