对比骨科手术机器人辅助微创治疗股骨粗隆间骨折手术与传统手术的疗效。

回顾分析50例股骨粗隆间骨折患者的临床资料，机器人手术组21例，常规手术组29例。其中男26例，女24例，平均年龄（70±15）岁；低能量生活伤44例、车祸伤4例、高处坠落伤2例，记录分析两组患者平均住院日、术前住院日、术中出血量、切口长度、手术时间以及围手术期输血量。所有手术均由经验丰富的骨伤同一团队完成，记录手术并发症，评价手术的效果。

两组平均住院日、术前住院日、手术时间无统计学差异；术中出血量（t=-5.159，P<0.001）、围手术期输血量（t=-3.123，P=0.003）、主钉切口长度（t=-8.877，P<0.001）、Hb（t=-2.285，P=0.033）及Hct下降方面（t=-2.064，P=0.052），机器人手术组较常规手术组有优势。所有患者3个月复查时均达临床愈合，术后DR示两组术后内固定优良率差异无统计学意义。术后4例患者出现深静脉血栓，2例患者骨折复位不良，7例内固定位置不佳。

本研究发现机器人辅助下精准、微创完成PFNA手术，较常规手术术中出血更少、主钉切口更小，在降低了临床用血量的同时在相同的住院时长下取得良好的疗效，该术式在患者高龄、基础条件差或临床用血量不足的情况下的稳定型骨折推荐使用。

Comparative orthopaedic surgery Robot-Assisted minimally invasive surgery and conventional surgical treatment of femoral intertrochanteric fracture effect.

Retrospective analysis of 50 cases of intertrochanteric fractures in patients with clinical information, including robotic surgery group 21 cases, general surgery group 30 Cases. 26 male and 24 female, with an average of (70±15) years. The injury mechanism was low energy injuries 44 cases, car accident injuries 4 cases and falling 2 cases. The the recorded average length of stay, preoperative hospital day, intraoperative blood loss, length, operation time and the amount of perioperative Blood transfusions were analyzed. All operations are done by experienced doctor and complications records, assessment of the effectiveness of the operation were recorded.

There was no statistical difference in the average hospitalization days, preoperative hospitalization days, and operation time between the two groups; intraoperative blood loss , perioperative blood transfusion, and length of the main staple incision , Hb and Hct decrease in robotic surgery group were better than the general surgery group. All patients reexamined at 3 m and all achieved clinical healing. Postoperative DR showed no statistically significant difference in the rate of internal fixation between the two groups. Deep venous thrombosis occurred in 4 patients after surgery, fracture reduction was poor in 2 patients, and internal fixation was poor in 7 patients.

This study found that robotic-assisted PFNA surgery can be performed accurately and minimally invasively, with less bleeding and smaller staple incisions compared with conventional surgery. It reduces clinical blood volume and achieves good results with the same length of hospital stay. Stable fractures are recommended for patients with advanced age, poor basic conditions, or insufficient blood for clinical use.
