When a factory accident completely severed both of Jiang’s legs at the thighs, the injury appeared to leave almost no path back to walking.

The 51-year-old worker was critically injured on Dec. 2, 2024, after becoming caught in industrial machinery. Both legs were completely separated from his body at the thigh level.

What followed was not a simple emergency operation.

A multidisciplinary surgical team at Suzhou Ruihua Orthopedic Hospital in China worked through the night for nearly eight hours, attempting something extraordinarily difficult: reattaching both legs and restoring enough circulation, nerve function and structural stability for them to survive.

The surgery was only the beginning.

Jiang would endure complications, additional procedures and nearly 20 months of rehabilitation before reaching the milestone that once seemed almost unimaginable.

He can now walk indoors with the help of a walker.

The Accident Left Both Legs Completely Severed

Jiang’s injuries were far beyond ordinary fractures or even severe crush injuries.

Both legs had been completely severed at the thighs by factory machinery.

In such an injury, surgeons are not simply repairing broken bones.

They must try to reconstruct multiple systems at once.

Bone has to be stabilized.

Major blood vessels must be reconnected quickly enough to restore circulation.

Muscles and tendons have to be repaired.

Nerves must be carefully joined in hopes that sensation and motor control can gradually return.

And all of those repairs must survive the immediate danger of blood loss, tissue damage, infection and other potentially life-threatening complications.

According to reports about Jiang’s case, more than 20 medical specialists became involved in his treatment.

The medical team decided to attempt bilateral leg replantation rather than accept permanent loss of both limbs.

It was an enormous gamble.

Surgeons Worked for Nearly Eight Hours

The operation lasted almost eight hours and continued through the night.

One of the first priorities was reconstructing the legs in a way that restored their basic physical alignment while also minimizing the amount of time the tissues remained without blood flow.

Surgeons worked on the bones, blood vessels, nerves and muscle structures.

The technical challenge was multiplied by the fact that they were not trying to save one completely severed limb.

They were trying to save two.

Restoring circulation was essential. Without adequate blood supply, reattached tissue cannot survive.

But reconnecting vessels is only one part of the process.

Even if the legs survived the initial operation, nobody could guarantee that Jiang would eventually regain enough nerve function, strength or coordination to stand and walk again.

Successful reattachment and useful recovery are two very different outcomes.

Jiang still faced a long and uncertain road.

The First Surgery Did Not End the Crisis

Stories about dramatic medical rescues can sometimes make recovery sound almost immediate.

Jiang’s experience was nothing like that.

The successful overnight operation was followed by months of treatment.

He experienced complications and needed additional procedures as doctors continued managing the condition of the replanted limbs.

External fixation devices were used during the recovery process and were eventually removed.

The challenge was not simply keeping Jiang alive or keeping the legs attached.

The real long-term question was whether his muscles, nerves and joints would recover enough function to support meaningful movement.

Nerves regenerate slowly.

Muscles weaken dramatically after major trauma and prolonged immobility.

Scar tissue can restrict movement.

Pain, swelling and limited sensation can complicate even basic rehabilitation.

For Jiang, every improvement required time.

Rehabilitation Became the Next Major Battle

Once his condition allowed it, rehabilitation became central to the recovery.

After such a devastating injury, walking could not simply resume when the wounds healed.

Jiang had to rebuild strength and retrain his body to use legs that had been completely detached and surgically replanted.

Over roughly 20 months, his progress accumulated gradually.

Eventually, he reached the point where he could stand and move indoors using a walking frame or walker.

He has also regained enough function to perform many daily activities.

Doctors have reported that sensation has returned down his legs to near the ankle area.

That detail is especially significant because nerve recovery after such an injury can take a very long time and may remain incomplete.

His current ability to walk with assistance does not mean his recovery is finished.

Independent walking remains a future goal.

But compared with the condition in which he arrived at the hospital, the change is extraordinary.

Why Reattaching Both Legs Is So Difficult

Limb replantation has been performed for decades, particularly involving fingers, hands and some arms or legs.

But the higher the amputation occurs on the body, the more complicated the operation becomes.

A complete thigh-level amputation involves large muscles, major arteries and veins, large nerves and a considerable amount of tissue.

The amount of muscle that can be damaged by interrupted circulation is especially important.

When circulation is cut off, tissue begins to deteriorate.

Restoring blood flow can itself create additional physiological stress as substances that accumulate in damaged tissues suddenly enter the circulation.

Performing the procedure on both legs increases those risks and dramatically expands the amount of reconstruction required.

That helps explain why Jiang’s case has attracted international attention.

Doctors and Chinese medical reports have described it as the first documented case in which complete bilateral thigh replantation ultimately resulted in the patient recovering walking ability.

Because that “first” designation comes from the hospital and reporting around the case, it is best understood as their assessment rather than an independently established worldwide record.

Even without that label, the outcome remains remarkable.

His Legs Did More Than Survive

The most important part of Jiang’s story is the difference between anatomical success and functional recovery.

A limb can technically survive replantation without ever returning to useful function.

Jiang’s progress went further.

Nearly 20 months after the accident, he is not merely living with two replanted legs.

He is using them.

He can move around indoors with assistance.

He can carry out much of his daily routine.

Sensation continues to return.

And his doctors believe further improvement may still be possible.

That does not erase the severity of what happened or guarantee a complete recovery.

He continues to require rehabilitation, and walking independently remains something he is working toward rather than something already achieved.

But the direction of his recovery is dramatically different from what the original injury might have suggested.

Twenty Months Changed the Meaning of the Accident

On Dec. 2, 2024, both of Jiang’s legs were completely severed by factory machinery.

Within hours, more than 20 medical professionals were involved in a race to reconstruct what had been destroyed.

They worked for nearly eight hours.

Then came more procedures, complications, healing and month after month of rehabilitation.

There was no single moment when the impossible suddenly became possible.

The outcome was built slowly — operation by operation, nerve by nerve, movement by movement.

Now, almost 20 months later, Jiang can use a walker to move through his home on the same two legs that were once completely separated from his body.

The surgery saved the limbs.

The months that followed are what taught them to support him again.
