To investigate robot-assisted percutaneous cannulated screw fixation for treating slipped capital femoral epiphysis, including acute, chronic, and acute-on-chronic slips. Our study included all stable and unstable slips.
Thirty-one children with unilateral SCFE were treated from October 2019 to October 2021. All 31 patients were followed up for 12-36 months, with an average follow-up time of 24.56 ± 6.73 months. The femoral epiphysis was fixed with a percutaneous cannulated screw assisted by a surgical robot.
All 31 femoral head epiphyses underwent successful fixation in one attempt. The average operation time and bleeding were 98.25 ± 15.13 min and 21.65 ± 11.25 ml, respectively. The average distance between the actual and planned entry points was 1.13 ± 0.58 mm and 0.91 ± 0.72 mm in the anteroposterior (AP) and lateral views, respectively. The actual insertion trajectory deviated from the planned position by 3.61 ± 1.34° and 2.33 ± 1.32° in the AP and lateral views, respectively. The average fluoroscopy time was 6.56 ± 3.23 times per screw. The Non-Arthritic Hip Score improved from 28.53 ± 9.17 preoperatively to 67.34 ± 6.21 at the last follow-up ( < 0.05), and the Harris hip score improved from 46.47 ± 15.34 to 89.63 ± 7.52 ( < 0.05). The wounds healed without avascular necrosis or chondrolysis of the femoral head.
Robot-assisted percutaneous cannulated screw fixation is effective for treating pediatric SCFE. Screw fixation was accurate and safe, and clinical outcomes were satisfactory.

探讨机器人辅助经皮空心螺钉固定术治疗股骨头骨骺滑脱，包括急性、慢性以及急性加重慢性型滑脱。我们的研究纳入了所有稳定型和不稳定型滑脱。
2019年10月至2021年10月，对31例单侧股骨头骨骺滑脱患儿进行了治疗。所有31例患者均随访12 - 36个月，平均随访时间为24.56 ± 6.73个月。在手术机器人辅助下，采用经皮空心螺钉固定股骨头骨骺。
31例股骨头骨骺均一次性成功固定。平均手术时间和出血量分别为98.25 ± 15.13分钟和21.65 ± 11.25毫升。在前后位（AP）和侧位片上，实际进针点与计划进针点的平均距离分别为1.13 ± 0.58毫米和0.91 ± 0.72毫米。在AP位和侧位片上，实际插入轨迹与计划位置的偏差分别为3.61 ± 1.34°和2.33 ± 1.32°。每颗螺钉的平均透视时间为6.56 ± 3.23次。非关节炎髋关节评分从术前的28.53 ± 9.17提高到末次随访时的67.34 ± 6.21（P < 0.05），Harris髋关节评分从46.47 ± 15.34提高到89.63 ± 7.52（P < 0.05）。伤口愈合，未发生股骨头缺血性坏死或软骨溶解。
机器人辅助经皮空心螺钉固定术治疗儿童股骨头骨骺滑脱有效。螺钉固定准确、安全，临床效果满意。
