To analyze the gender, age, fracture classification and variation trend of adult intertrochanteric fractures treated in a single-center hospital in ten years.
The data of adult (age ≥ 16 years) intertrochanteric fractures admitted to the Third Hospital of Hebei Medical University from January 2003 to December 2012 were collected retrospectively. All the fractures were acute and the pathological or periprosthetic fractures were excluded. The radiography of fracture were classified by same experienced orthopedic resident and verified by two orthopedic deans and one radiologist. The gender, age and fracture classification were analyzed and compared between January 2003 to December 2007 and January 2008 to December 2012.
A total of 3 201 cases were collected. The adult intertrochanteric fractures accounted for 2.97% of all adult fractures and 43.76% of adult proximal femoral fractures. Of all fractures 64.98% were elderly ( ≥ 60 years) and 35.02% were middle-aged (16-59 years). In elderly, female were common (57.78%) while in middle-aged were male commonly (79.13%). According to Evans classification, instable fractures were more common (68.92%). According to AO classification, the most common type was A2 (49.67%) and the least was A3 (15.93%). Comparing between January 2003 to December 2012 and January 2008 to December 2012, the proportion of intertrochanteric fracture of adult fracture was decreased by 0.31% (χ² = 9.29, P = 0.002)and the proportion of intertrochanteric fracture of adult proximal femoral fractures was decreased by 3.15% (χ² = 7.35, P = 0.007). The proportion of elderly patients, female and stable fractures was increased by 14.35% (χ² = 71.98, P < 0.01), 4.04% (χ² = 8.16, P = 0.004) and 5.62% (χ² = 11.7, P = 0.001), respectively. The proportion of AO classification was not significantly verified (χ² = 3.24, P = 0.198).
The intertrochanteric fractures are most common in elderly patients, A2-type of AO Classification and stable (Evans III, IV, V) in Evans classification. Compared with the previous five years, the proportions of female, elderly and stable (Evans I, II) fracture increase in last 5 years.
分析某单中心医院十年间收治的成人股骨转子间骨折患者的性别、年龄、骨折分型及变化趋势。
回顾性收集2003年1月至2012年12月在河北医科大学第三医院收治的成人（年龄≥16岁）股骨转子间骨折患者资料。所有骨折均为急性骨折，排除病理性骨折及假体周围骨折。由同一名经验丰富的骨科住院医师对骨折X线片进行分型，并经两名骨科主任及一名放射科医师核实。分析并比较2003年1月至2007年12月与2008年1月至2012年12月患者的性别、年龄及骨折分型。
共收集到3201例患者。成人股骨转子间骨折占所有成人骨折的2.97%，占成人股骨近端骨折的43.76%。所有骨折患者中，64.98%为老年人（≥60岁），35.02%为中年人（16 - 59岁）。老年人中女性居多（57.78%），中年人中男性居多（79.13%）。按Evans分型，不稳定骨折更为常见（68.92%）。按AO分型，最常见类型为A2型（49.67%），最少见为A3型（15.93%）。比较2003年1月至2012年与2008年1月至2012年，成人骨折中股骨转子间骨折的比例下降了0.31%（χ² = 9.29，P = 0.002），成人股骨近端骨折中股骨转子间骨折的比例下降了3.15%（χ² = 7.35，P = 0.007）。老年患者、女性及稳定骨折患者的比例分别增加了14.35%（χ² = 71.98，P < 0.01）、4.04%（χ² = 8.16，P = 0.004）及5.62%（χ² = 11.7，P = 0.001）。AO分型比例差异无统计学意义（χ² = 3.24，P = 0.198）。
股骨转子间骨折在老年患者中最为常见，AO分型中以A2型多见，Evans分型中以稳定型（Evans III、IV、V型）多见。与前五年相比，近五年女性、老年及稳定型（Evans I、II型）骨折的比例增加。
