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.
