目的 通過比較閉合復位與切開復位髓內(nèi)針內(nèi)固定治療老年股骨粗隆間骨折的療效，探討影響髓內(nèi)針內(nèi)固定治療老年股骨粗隆間骨折療效的主要因素。方法 將股骨粗隆間骨折患者隨機分為實驗組與對照組，實驗組進行閉合復位髓內(nèi)針內(nèi)固定術治療，對照組進行切開復位髓內(nèi)針內(nèi)固定術治療，比較兩組的手術時間、住院時間及生活能力得分。結果 實驗組的手術時間短于對照組，差異具有統(tǒng)計學意義（P＜0.05），而在住院時間和生活能力得分上，兩組之間的差異不具有統(tǒng)計學意義（P＞0.05）。結論 切開或閉合復位方式不是影響髓內(nèi)針內(nèi)固定治療老年股骨粗隆間骨折療效的主要因素，髓內(nèi)針內(nèi)固定運用的中軸性固定效應，是影響療效的主要因素之一。因此在臨床可根據(jù)老年患者的具體情況選擇合適的復位方式，以達到更好的治療效果。 |

Objective To investigate the main factors in the intramedullary nail fixation of intertrochanteric fractures in elderly patients by comparing the curative effects of closed reduction and open reduction in the intramedullary nail fixation of intertrochanteric fractures. Methods The femoral intertrochanteric fracture patients were randomly divided into experimental group and control group. The experimental group was treated with closed reduction and intramedullary fixation, and the control group was treated with open reduction and internal fixation. The parameters of operation time, days in hospital, and the scores of activities of daily living were compared. Results The operation time of the experimental group was shorter than that of the control group (P<0.05), the differences of hospitalization time and the scores of activities of daily living were not significant (P>0.05). Conclusions Reduction mode does not affect the efficacy of intramedullary nail fixation for the intertrochanteric fracture, however the axial fixed effect of intramedullary fixation is one of the main factor for the curative effect. Therefore, the doctor may select the proper reduction mode according to the patient’s condition for a better therapeutic effect. |
