[Abstract] Objective To explore the role of hollow bit in DHS treating intertrochanteric fracture. Methods 52 cases were divided into two groups according to the different operation methods from January to June 2007,conventional group of 28 cases,hollow bit group of 24 cases, contrast parameters including the average times of feeding needle and X-ray exposure, operation time,amount of bleeding. Results It had no significant difference (P>0.05) in feeding needle times, but the average of X-ray exposure times,operation time and amount of bleeding in hollow bit group were obviously less than conventional group(P<0.05). Conclusion DHS with hollow bit was a feasible and effective method in treatment of intertrochanteric fracture, which could shorten the operation time, decrease the amount of bleeding, reduced the radiation dose of doctors and patients, so it was worthy of promotion.

動力髖螺釘(dynamic hip screw,DHS)是專門為股骨轉子間骨折設計的內固定器,因具有靜力性加壓及動力性加壓作用而廣泛應用于各種類型的股骨轉子間骨折。由于傳統的DHS內固定手術具有切口大、手術時間長、術中出血較多[1-3]等缺點,為縮短手術時間及減少出血,筆者于2007年1月~2012年6月將52例DHS內固定患者按術中不同的操作方法分為常規組與應用空心鉆頭組,通過對兩組的術中情況進行對比,自覺應用空心鉆頭組術中的效果明顯要優于常規組,現報道如下。
