目的:探讨TiRobot骨科机器人导航外固定支架固定在肘关节松解术中的应用效果。方法:回顾性分析2018年4月至2019年8月于北京积水潭医院创伤骨科术中使用TiRobot机器人导航辅助肘关节外固定支架固定治疗11例因肘关节僵硬行肘关节松解术的患者资料。男9例，女2例；年龄21~66岁，平均39.3岁；记录患者末次随访时肘关节活动度并与术前进行比较，同时记录疼痛视觉模拟评分（VAS）、Mayo肘关节功能评分（MEPS）及并发症发生情况。结果:11例患者术中机器人导航辅助下定位肘关节旋转中心轴，入点偏差平均0.21 mm（0.05~0.41 mm），出点偏差平均0.23 mm (0.06~0.38 mm)。术后所有患者获平均25.8个月（16~32个月）随访。末次随访时11例患者屈伸、旋转活动度分别为133.0°(134.9°，138.7°)、164.6°±17.5°，均较术前[0.8°(0°，33.7°)、122.9°±49.0°]显著提高，差异均有统计学意义（n P<0.05）。末次随访时VAS评分平均为0.2分（0~1分），MEPS评分平均为96.8分（85~100分），其中9例为优，2例为良。无患者出现桡神经损伤、固定针松动或断裂、针道感染、固定针周围骨折等并发症。n 结论:肘关节松解术中行TiRobot骨科机器人导航辅助肘关节外固定支架固定，旋转中心轴定位精确，患者能获得较为满意的功能预后。“,”Objective:To investigate the efficacy of TiRobot navigation for hinged external fixation in elbow arthrolysis.Methods:The 11 patients were retrospectively analyzed who had been treated by elbow arthrolysis at Department of Traumatology and Orthopedics, Beijing Jishuitan Hospital using TiRobot navigation for hinged external fixation. There were 9 males and 2 females with a mean age of 39.3 years (from 21 to 66 years). Their elbow range of motion (ROM) was compared between preoperation and the final follow-up. Their visual analogue scale (VAS) and Mayo elbow performance score (MEPS) and complications were documented at the final follow-up.Results:The rotation axis of the elbow joint was positioned with the aid of intraoperative robot navigation in 11 patients.The deviation of entry point averaged 0.21 mm (from 0.05 to 0.41 mm) and the deviation of exit point 0.23 mm (from 0.06 to 0.38 mm). The follow-up time for the 11 patients averaged 25.8 months (from 16 to 32 months). Their elbow flexion and extension was 133.0° (134.9°, 138.7°) and rotation 164.6° ±17.5° at the final follow-up, significantly improved compared with their preoperative values [0.8°(0°, 33.7°) and 122.9°±49.0°] (n P<0.05). Their VAS averaged 0.2 (from 0 to 1) and MEPS 96.8 (from 85 to 100) at the final follow-up, giving 9 excellent and 2 good cases. There was no case of radial nerve injury, pin instability, pin breakage, pin infection or peri-pin fracture.n Conclusion:When TiRobot navigation is used for hinged external fixation in elbow arthrolysis, the axis of rotation can be accurately located, leading to satisfactory functional outcomes for the patients.

慢性骨髓炎是一种常见疾病。骨髓炎传统治疗疗程是在彻底清创后使用4~6周的静脉注射抗生素治疗。然而，并没有确凿的证据证实，这一疗程相较于其他疗程的抗生素治疗具有优越性。近年来，随着对该疾病的认识愈发深入，各项治疗技术不断发展，抗生素的使用方案也发生了改变。本文就慢性骨髓炎抗生素应用疗程的最新进展作一综述。“,”Chronic osteomyelitis is a common disease. Traditionally, osteomyelitis is treated with parenteral a
随着计算机、导航和机器人技术的革新，临床应用机器人辅助骨科的手术越来越多，如关节置换手术、脊柱手术、骨肿瘤手术、关节镜检查和骨折固定手术，为实现临床疾病微创、精准、个性化治疗提供了一个新的方向。TiRobot是我国自主研发的骨科机器人系统，在脊柱、创伤等骨科手术中得到了广泛的应用。本文对TiRobot在骨折手术中的应用及远程手术的实施进行综述，介绍TiRobot辅助脊柱颈椎骨折、胸腰椎骨折、骨盆髋臼骨折、髋部骨折以及手足部骨折手术的应用进展。“,”With technological innovation
