Patient with both legs severed at thigh level walks again after doctors perform rare replantation surgery in East China’s Jiangsu_我的网站

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.

四 | 单亩每年电费从80元降到50元；4人一天可以完成600亩施肥作业，以前30人一天都做不到100亩。”　　在采收环节，机械化作业的降本优势同样凸显。杨学算了一笔账：传统人工砍收、装车，以园区亩产7吨甘蔗、按每吨160元计算，成本超1100元；换成机械化收割，每亩约200元国家机收补贴，连片蔗田农户承担每亩50元至80元机收费，规模越大效益越可观。

五 | 园区推行蔗叶粉碎还田技术，每亩还可节省三四十元的复合肥支出。图为广西崇左市扶绥县渠黎镇甜蜜之光现代甘蔗产业园种植的甘蔗。陈沿佑 摄　　从一株健康种苗到一片高产蔗田，科技创新正在不断重塑甘蔗产业发展模式。近年来，中国热带农业科学院热带生物技术研究所持续面向甘蔗产业发展需求，联动广西农业科学院等科研单位，围绕甘蔗品种改良、种苗繁育、病虫草害综合防控、绿色高效栽培、机械化收获等方向开展关键技术攻关，推动科技成果从实验室走向田间。　　“广西是全国甘蔗核心产区，种植面积1200多万亩，产糖量占全国六成以上。”中国热带农业科学院热带生物技术研究所甘蔗中心研究员吴期滨介绍，中国甘蔗栽培技术历经传统经验积累、现代技术奠基、绿色高效智能化转型三个阶段。

六 | 眼下业内重点聚焦两大攻关方向：选育适配机械化采收的优质甘蔗品种，研发适配优良品种的专用农机，推动农机与农艺深度融合。
