A 51-year-old patient surnamed Jiang raises his legs after more than a year of treatment following an eight-hour operation at Suzhou Ruihua Orthopedic Hospital in 2024 to reattach both legs, which had been completely severed at the thighs. Photo: Yangtze Evening PostChinese doctors have completed what they called as the world's first replantation involving the complete severing of both legs at thigh level, with the patient now able to walk indoors using a walker following a nearly eight-hour operation, according to a recent report by the Yangtze Evening Post.
The patient, a 51-year-old surnamed Jiang, had both legs completely severed at the thighs in a machinery accident at a factory on December 2, 2024. A multidisciplinary team from the trauma orthopedics and joint surgery departments at Suzhou Ruihua Orthopedic Hospital, in East China's Jiangsu Province, worked through the night for nearly eight hours to reattach the two limbs, the report said.
Li Changsong, head of a trauma orthopedics team at the hospital, told the Yangtze Evening Post on Tuesday that Jiang can now walk indoors with a walker and manage most daily activities without assistance. Sensation in his lower limbs has also recovered to the area above his ankles.
"He is still recovering and is expected to gradually stop using crutches and eventually walk independently," Li was quoted as saying by the Yangtze Evening Post on Wednesday.
In March last year, shortly after the external fixators were removed from both legs, Jiang could already lift his legs freely while lying in bed. Sensation had returned as far down as the middle of his lower legs, and he was discharged from the hospital on March 5. His main goal at the time was to stand and walk again through rehabilitation, according to the report. 
More than a year later, Jiang has moved from being confined to bed to lifting his legs and then standing and walking, the report said, noting that his rehabilitation is still ongoing.
The recovery process has not been without complications. Jiang developed localized skin necrosis after the operation and underwent flap reconstruction surgeries. He later required bone grafting and reinforced internal fixation of both femurs after severe open comminuted fractures resulted in femoral nonunion.
Li said Jiang is now in good overall condition, with his legs approximately equal in length.
"A novelty assessment conducted by the Jiangsu Institute of Medical Information confirmed this as the world's first case of replantation following the complete severing of both thighs," Li said. 
Li said the case was considered a world first primarily because both legs were completely severed at thigh level simultaneously, an extremely rare injury. The hospital had previously accumulated extensive experience in replanting single limbs and lower legs, while its expertise in fracture fixation, vascular anastomosis and nerve repair provided an important technical foundation for the operation, according to the report.
Li did not give a timetable for when Jiang might be able to stop using a walker completely.
"Recovery varies from person to person. We still need to monitor his muscle strength, nerve sensation and fracture healing," Li said. Based on his current progress, however, Jiang's walking ability could continue to improve, the Yangtze Evening Post reported.

。      记者从8月20日交通运输部召开的例行发布会上获悉，我国正加快人工智能在交通运输领域的应用，持续推进典型应用场景创新，已发布首批41个重点典型场景建设指引。到2030年，将开放一批高价值应用场景，形成一批高水平算法模型，涌现一批“人工智能+交通运输”新基础设施、新技术装备、新服务模式、新产业形态，推动人工智能更好地引领交通运输领域新质生产力的发展。

二 |   近年来，随着人工智能成为新一轮科技革命和产业变革的核心引擎，交通运输领域也成为人工智能落地和规模化应用的主阵地。去年9月，交通运输部联合六部门出台了《关于“人工智能+交通运输”的实施意见》，明确了人工智能在交通运输领域的重点应用方向。今年6月，交通运输部又会同四部门印发了《“人工智能+交通运输”典型应用场景创新行动方案》，全面启动典型应用场景创新行动，依托人工智能技术驱动交通强国建设。  “目前，我们已围绕智能驾驶、智慧公路、智能铁路、智能邮政等10大方向，发布了第一批41个重点典型场景建设指引，正式启动首批典型应用场景项目创建工作。”交通运输部科技司司长徐文强表示，将依托人工智能技术补齐行业短板，推动成熟技术规模推广、集成技术示范融合、核心场景集中攻关，培育自主可控的交通人工智能产业生态。  具体来看，在智能邮政方面，国家邮政局政策法规司副司长徐华荣介绍，邮政业聚焦邮政快递生产、服务等方面，推广应用智能安检系统，可自动识别并剔除违禁物品，检测范围覆盖管制器具、烟花爆竹等100多个品类；试点应用无人派送技术，在全国多个地区投用超1.6万台无人快递车，投放400多架无人机，开展末端配送服务，提升了山区、海岛等交通不便地区寄递服务质效。  在智能铁路方面，国家铁路局科技与法制司副司长刘燕介绍，铁路部门强化平台建设，加强高速列车智能运维、BIM软件等人工智能技术相关的铁路行业重点实验室和工程研究中心建设；推动安全管理，在高铁沿线采用高铁线路环境安全管控平台，通过视频和雷达融合的人工智能分析，自动识别侵入轨道的人员和异物。

三 | 目前，我国高铁沿线已接入5.6万路摄像机，覆盖隧道口、桥头等重点处所，截至2026年4月，已累计处置近31万条有效报警。  展望未来，随着“人工智能+交通运输”典型应用场景加速落地，交通运输领域“一网四化”建设有望得到进一步支撑。  “‘一网四化’是当前及今后一个时期，综合交通运输高质量发展的主题主线。‘人工智能+交通运输’典型应用场景创新行动，是支撑‘一网四化’落地的核心技术引擎。”徐文强表示，未来将以数据融通促进一体化融合；以模式变革赋能安全化提升，以人工智能推动安全治理从“事后处置”转向“事前预警”，从“人防为主”转向“技防和智防”；以系统重构赋能数智化升级，人工智能将重构交通系统，实现设施、装备等方面的升级；以降本增效促进绿色化转型，人工智能将在运输组织、设施运维等多个环节动态优化资源配置，实现节能降碳。  此外，相关专家认为，随着人工智能典型应用场景加快落地，交通运输领域的数智化转型将进一步提速。人工智能与交通运输业务深度融合，有望推动行业从单一环节的数字化改造转向全链条、全要素的智能化升级，进而提升交通领域的基础设施运行效率、运输组织协同能力和安全治理水平。
