Chapter 1649: 1593 Hidden Dangers Left by Failed Ceramic Joint Implantation

The Wang family elder walked into the conference room, saw a stainless steel tray on the table with a blazing fire inside, and froze for a moment.

Zheng Ren and Su Yun were smoking.

Is the way they light their cigarettes really that unusual?

He muttered a complaint to himself, then recalled Zheng Ren smiling, grabbing Song En's head, speaking gently while asking him questions and simultaneously making the motion of hitting the wall.

His heart turned cold, and all his complaints vanished into nothing.

"Zheng Boss, what's this?" he asked with a chuckle.

"Song En put a worm on my body, I dug it out and burned it—did you smell it?" Zheng Ren said, cigarette in mouth, while Xie Yiren disinfected his arm.

"..." The Wang family elder was truly stunned.

He avoids contact with gu masters because they often place gu in unseen places.

Zheng Boss is so badass? They planted a worm, yet he dug it out.

"Anything?" Zheng Ren asked.

"Zheng Boss, this is the commander-in-chief of the National Guard." The Wang family elder regained some of his former dignity, introducing the elderly man in military uniform beside him to Zheng Ren.

"Hello." Zheng Ren greeted in English.

"Because bandits have appeared here, for everyone's personal safety, the subsequent security work will be handled by the National Guard."

"Do you have guns?" Zheng Ren asked after exhaling a puff of smoke.

"Yes."

"Lao Fan, squad leader, what are you used to using?" Zheng Ren asked.

The two reported a gun model.

The Wang family elder's expression was somewhat awkward.

"Perimeter security will be handled by the National Guard, and this conference room by our people." Zheng Ren said without hesitation: "Mr. Wang, what do you think?"

His words were polite, but his tone was extremely firm.

The Wang family elder was troubled, but recalling Zheng Boss's recent threat, he immediately agreed.

This person appears honest and simple, but is actually malicious, splashing dirty water on himself without blinking. He seems not to care who harmed his father, only caring about the safety of those who came with him.

After exchanging a few words with the National Guard commander-in-chief, the uniformed guards left unhappily. A few minutes later, the firearms requested by Fan Tian Shui and Zhu Fengyu were delivered.

Zheng Ren didn't understand and didn't go to look.

"Zheng Boss, is there anything else you need on your side?" the Wang family elder asked considerately.

"Su Yun, let's continue." Zheng Ren said.

"Okay." Su Yun glanced at Fan Tian Shui, saw him fiddling with his firearms, and said skillfully: "Lao Fan, we've said hello abroad; anyone who barges in after that will be dealt with lethally."

Fan Tian Shui grinned, indicating he understood.

It had been a long time since he touched a gun; feeling the metal texture, he was as happy as meeting an old friend.

"No problem, right?" Su Yun still felt uneasy.

Fan Tian Shui ran his finger over the magazine, smiling: "Enough ammo—I could kill everyone in this hospital."

"..." Su Yun today witnessed Fan Tian Shui's true combat capability, knowing this guy wasn't bragging.

He whistled, then followed Zheng Ren out.

"Zheng Boss, is the poisoning you mentioned earlier true?"

After going out, the Wang family elder cautiously asked.

"Hmm, considering it's a heavy metal poisoning that would cause your father's current condition." Zheng Ren regained his composure, returning to doctor mode: "We need a blood analysis to confirm; also, he had a hip replacement three years ago—I will personally perform a 64-slice CT three-dimensional reconstruction."

"What else needs to be checked?" The Wang family elder, having lost his own opinions, felt some regret.

He originally just wanted to invite a doctor to see the illness, but who knew they'd brought a killing star.

Returning to the operation room outside the ward, looking through the transparent glass, he saw Old Mr. Wang still lying on the bed. Zheng Ren remarked that the glass was likely bulletproof; otherwise, just now Song En's head would surely have smashed it.

He took a sheet of paper, wrote down several metal element symbols, and said: "Test the levels of these metals. Also, which hospital's doctor performed the old man's hip replacement? What material is the hip joint made of? I need the full report."

"Also, are there any other metal implantation surgeries?"

The Wang family elder dared not waste words, denied any metal implantation surgery, noted Zheng Ren's requests, and arranged for people to carry them out.

"Boss, do you suspect someone implanted poison in the hip joint?" Su Yun asked.

"There's no poison." Zheng Ren pointed at the image, saying: "Here, judging by imaging density, it's definitely not postoperative local tissue adhesion, but fragments left over from the initial attempt to implant a ceramic hip joint."

"..." Su Yun was stunned.

Zheng Ren's speculation was incredibly unbelievable.

"There was nothing like that in the early cases, but when I just looked up Old Mr. Wang's medical history, the surgical record noted: 'Ceramic hip implant failed, removed and replaced with a full-metal structure hip joint.'"

"In the early 1960s, Sir John Charnley pioneered low-friction joint replacement surgery, thereby launching a revolution in the field of artificial joint replacement."

"The first total ceramic hip joint was fixed on the acetabular side without bone cement, while on the femoral side the ceramic head was fixed to the femoral stem with bone cement."

"Although the friction performance of alumina ceramic was praised from the start of its application, problems remain in practice. Ceramic material is very brittle, with a risk of fracture."

"Old Mr. Wang used either a ceramic-on-ceramic mode or the latest porcelain, which is sturdier than the previous generation's yellow ware. Unfortunately, the surgery failed. Thus we surmise the surgeon should have removed the ceramic at that time and replaced it with a total metal hip joint."

"Mr. Wang? Was there such a situation back then?" After speaking, Zheng Ren turned to look at the Wang family elder, saying: "I think the surgery, according to the record, was done at Massachusetts General Hospital."

"Hmm." The Wang family elder suppressed his surprise and said: "Initially it was indeed said to use the latest porcelain artificial hip joint. But during the operation, a doctor came to explain that my father's physical condition didn't allow it, so they switched intraoperatively to a full-metal structure artificial hip joint."

Su Yun was astonished.

This isn't something that can be solved with X-ray vision.

It requires strong medical knowledge as background, keen observation, and meticulous analysis.

The strongest aspect is the boss's image-reading ability.

This is a test of comprehensive ability, and the boss scored full marks in it.

"Hmm," we can't say that yet; at least we must wait for the test results before speaking.

Now the eldest son of the Wang family brimmed with confidence; he already tended to believe Master Yan's claim of a ten‑year lifespan extension. Zheng Lao Ban himself reconstructed the truth of what happened during the hip joint replacement Shou Bing 3 years ago—this could practically be called a miracle.

Blood was drawn and sent for testing, an assistant made contact, and then they pushed Mr. Wang to undergo the slice CT three-dimensional reconstruction.
