Objective To study of long-stem proshetic replacement of comminuted intertrochanteric fracture of femur in the elderly patients. Method Fifteen consecutive patiens who were more than 70 years old and had an unstable intertrochanteric fracture were treated with long-stem proshetic replacement from 2001 to 2003.The average hospital stay ,the average time to amblulation with full-weith bearing on the operated limb after operation and complication were observed. Result The average hospital stay of the patiens was 16 days,,the average time to amblulation was 14 days , the pain of the hip was two cases. Conclusion Long-stem proshetic replacement of comminuted intertrochanteric fracture of femur in the elderly pateins may be a suitable alternative to internal fixation because the prothesis provides for early full weigh-bearing and rapid rehabilitation.

Objective To analyze the effect of clavicular hook plate(CHP) in treating distal clavicular fracture and acromioclavicular joint dislocation. Methods Eighteen patients with distal clavicular fracture(NeerⅡ) and acromioclavicular joint disclocation(Tossy Ⅲ) were treated by CHP. Results Sixteen patients were observed after operation,according to Lazzcano curative effect standard, fifteen cases were excellent, take 93.75 percent,1 case was good, with 6.25 percent, the excellent and good rates were 100.00 percent. The phenomenon such as the steel plate fracture,loose,escape hook and acromioclavicular joint re-dislocation were not happened. Conclusion CHP is an effective,scientific and convenience way for distal clavicular fracture and acromioclavicular joint dislocation,it worth being promoted.
