摘要：

目的通過(guò)對(duì)股骨前弓角在股骨粗隆間骨折（intertrochanteric fracture,IF）髓內(nèi)釘內(nèi)固定的生物力學(xué)分析，探討股骨前弓角在股骨粗隆間骨折臨床治療中的意義。方法對(duì)股骨粗隆間骨折進(jìn)行生物力學(xué)分析，然后對(duì)2013年1月至2019年1月民航總醫(yī)院骨科收治的股骨粗隆間骨折手術(shù)患者266例進(jìn)行回顧性研究。患者分為70歲以上年齡組和70歲以下年齡組，均行髓內(nèi)釘內(nèi)固定手術(shù)治療，對(duì)股骨前弓角、股骨大粗隆頂點(diǎn)至股骨前弓角頂點(diǎn)的距離（頂尖距）及術(shù)后恢復(fù)Harris評(píng)分進(jìn)行統(tǒng)計(jì)學(xué)分析。結(jié)果股骨前弓角及Harris評(píng)分兩組比較有統(tǒng)計(jì)學(xué)意義（P<0.05），頂尖距兩組比較無(wú)統(tǒng)計(jì)學(xué)意義（p>0.05）。70歲以上年齡組女性股骨前弓角（7.71±1.94°）大于男性股骨前弓角（6.41±2.05°）（P<0.05），而男性頂尖距（184.65 cm±19.31cm）大于女性頂尖距（176.50 cm±17.83cm）（P<0.05），術(shù)后恢復(fù)harris評(píng)分未見(jiàn)明顯差別（p>0.05）。結(jié)論股骨前弓角在股骨粗隆間骨折髓內(nèi)釘內(nèi)固定生物力學(xué)固定中具有重要意義，臨床治療中股骨前弓角和頂尖距可作為重要參考以取得最佳的臨床效果。

Objective To study the main factors influencing the curative effect of intertrochanteric fracture （IF）through the biomechanical analysis of the fixation of the anterior arch angle of femur with intramedullary nail. Methods The biomechanical analysis of intertrochanteric fracture was carried out. From January 2013 to January 2019, 266 patients with intertrochanteric fracture in orthopaedic ward of civil aviation general hospital were studied retrospectively. All patients were treated with intramedullary nail fixation, divided into the age group over 70 years old and the age group under 70 years old. In the age group over 70 years old, the anterior arch Angle of femur was greater than that of male femur, while the distance between the apex of femur greater trochanter and the apex of femoral anterior arch angle of male femur was greater than that between the apex of femur greater trochanter and the apex of femur anterior arch angle of female femur.No significant difference was found in postoperative recovery Harris score. Results There was significant difference in anterior femoral arch angle and Harris score between the two groups (P < 0.05), but there was no significant difference in apical distance between the two groups (P > 0.05).Conclusions The angle of anterior arch of femur is of great significance in the biomechanical fixation of intramedullary nail for intertrochanteric fracture of femur. It can be used as an important reference to select the appropriate intramedullary nail in the clinical treatment to obtain the best clinical effect.
