The bone in the shoulder area is “eaten†by the tumor. Is the entire shoulder joint cut off or the necrotic shoulder blade replaced? Recently, Shenzhen Second People’s Hospital used 3D printing technology to prepare a titanium alloy prosthesis that perfectly matches the patient's shoulder blade. Replace the scapula of the original tumor necrosis and create a new "iron shoulder". According to reports, this is the first "shoulder bone 3D printing titanium alloy prosthesis implantation" in Shenzhen and even in South China.
Who moved my shoulder blade?
The patient, Ms. Li, is a Jieyang person. Last year, she had pain in her left shoulder. After that, her left scapula began to swell and the pain was unbearable. Finally, life was disturbed. "It is very inconvenient to comb your hair and wear your hands.
In March of this year, she came to Shenzhen to inspect and found that she had an invasive giant scapular tumor.
"Fortunately, it is timely to cure, or it may be amputated after 2 months." Zhang Shiquan, deputy director of the Department of Bone and Joint and Oncology, Shenzhen Second People's Hospital, said that most of the invasive scapular tumors of Ms. Li will develop into malignant tumors. And there is osteolytic destruction, which will slowly "eat" the good bones of the human body. The bones of her shoulders 3/4 have been “eaten†by the tumor. If not operated in time, more bones will be “smashed†into the muscle tissue, even if the surgery can not completely remove it, 1-2 After the month, Ms. Li may have to face the risk of amputation.
How does the shoulder blade "print" out?
Zhang Shiquan said that for the scapular tumor, the traditional method is resection. After the whole shoulder joint is cut off, the operation is not only risky, but the patient can no longer take care of himself after being restored and become disabled.
The hospital decided to conduct a therapeutic study with 3D Hi-Tech, and for the first time, Ms. Lin's treatment used 3D printing technology to prepare a titanium alloy prosthesis that was completely consistent with the patient's shoulder blade and implanted in a bone tumor patient.
So how exactly does the shoulder blade "print" out?
Step1:
The collected data of the size and shape of the left shoulder blade of Ms. Li was printed by 3D technology to produce a completely consistent model.
Step2:
The surgical plan was designed according to the model, and the screw holes and the resection boundary of the operation were marked on the model to achieve accurate operation.
Step2:
The surgical plan was designed according to the model, and the screw holes and the resection boundary of the operation were marked on the model to achieve accurate operation.
Step4:
Complete resection of the tumor for Ms. Li
Step5:
A titanium alloy artificial scapula is implanted into a patient.
Since the 3D printing achieves “tailoringâ€, the titanium alloy artificial shoulder blade can be accurately matched.
It is reported that the cost of artificially customized joint surgery is about 100,000. Tan Jifeng revealed that after Ms. Li’s replacement surgery, she is in good physical condition and can be discharged after one or two days. After half a year, she can fully recover her life.
