摘要
目的：评价和比较智能骨折复位机器人系统在股骨干骨折闭式复位髓内钉治疗中的效果与常规透视辅助人工复位固定的效果。方法：在这项前瞻性、非随机对照研究中，纳入30例新诊断的股骨干骨折患者，实验组（机器人辅助）15例，对照组（常规）15例。实验组采用骨科手术导航系统辅助闭合复位和髓内钉，对照组采用透视辅助手工复位和固定。比较两组复位时间、总手术时间、术中透视计数、出血量、复位误差。结果：两组的基线特征相似。实验组术中透视次数明显少于对照组（36.67±25.41 vs. 117.26±61.28）P结论：机器人辅助入路骨折复位更精确，术中x线透视次数更少，与常规微创治疗股骨骨折方法相比具有明显优势。
Robot-assisted closed reduction of femoral shaft fractures: a prospective controlled study.
Purpose: To evaluate and compare the effectiveness of an intelligent fracture reduction robotic system in assisting closed reduction and intramedullary nailing of femoral shaft fractures with that of conventional fluoroscopy-assisted manual reduction and fixation.
Methods: In this prospective, non-randomized controlled study, 30 patients with newly diagnosed femoral shaft fractures were enrolled, with 15 cases in the experimental group (robot-assisted) and 15 cases in the control group (conventional). The experimental group utilized an orthopaedic surgical navigation system to assist in closed reduction and intramedullary nailing, while the control group underwent fluoroscopy-assisted manual reduction and fixation. The reduction time, total operation time, intraoperative fluoroscopy count, blood loss, and reduction error were compared between the two groups.
Results: Baseline characteristics were similar across both groups. The experimental group required significantly fewer intraoperative fluoroscopies (36.67 ± 25.41 vs. 117.26 ± 61.28, P < 0.001). Postoperative femoral length discrepancy (1.74 ± 1.37 mm) and anteversion difference (3.66 ± 3.37°) were significantly smaller in the experimental group compared to the control group (4.16 ± 2.67 mm, P = 0.004; 13.81 ± 9.58°, P = 0.001). Intraoperative blood loss was comparable between groups (experimental group: 207.33 ± 119.91 mL vs. control group: 240.00 ± 139.13 mL, P = 0.497). Reduction time was not statistically significant (experimental group: 74.27 ± 27.38 min vs. control group: 69.73 ± 34.10 min, P = 0.691).
Conclusions: The robot-assisted approach provided more precise fracture reduction, required fewer intraoperative X-ray fluoroscopies, and offered significant advantages over the conventional method for the minimally invasive treatment of femoral fractures.
期刊介绍：
International Orthopaedics, the Official Journal of the Société Internationale de Chirurgie Orthopédique et de Traumatologie (SICOT) , publishes original papers from all over the world. The articles deal with clinical orthopaedic surgery or basic research directly connected with orthopaedic surgery. International Orthopaedics will also link all the members of SICOT by means of an insert that will be concerned with SICOT matters.
Finally, it is expected that news and information regarding all aspects of orthopaedic surgery, including meetings, panels, instructional courses, etc. will be brought to the attention of the readers.
Manuscripts submitted for publication must contain a statement to the effect that all human studies have been approved by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted.
Reports of animal experiments must state that the "Principles of laboratory animal care" (NIH publication No. 85-23, revised 1985) were followed, as well as specific national laws (e.g. the current version of the German Law on the Protection of Animals) where applicable.
The editors reserve the right to reject manuscripts that do not comply with the above-mentioned requirements. The author will be held responsible for false statements or for failure to fulfil the above-mentioned requirements.
