3D printing technology is a cutting-edge innovation that can create complex and customized objects layer by layer from digital models. In recent years, 3D printing technology has been widely applied in various fields, especially in surgery and medical industry. 3D printing technology can provide personalized and precise solutions for patients with different needs and conditions, and improve the quality and efficiency of surgical procedures and outcomes.<\/p>\n
In this post, we will share with you three cases of metal 3D printing applications in surgery and medical industry, which demonstrate the advantages and potential of this technology. These cases are:<\/p>\n
\n
Case 1: A new type of 3D printed porous tantalum metal device for spinal fusion surgery without bone grafting<\/li>\n
Case 2: A novel surgery using 3D printed porous vertebral fusion device for spinal cord compression<\/li>\n
Case 3: A successful revision surgery using 3D printed porous artificial acetabulum for hip joint prosthesis failure<\/li>\n<\/ul>\n
Case 1: A New Type of 3D Printed Porous Tantalum Metal Device for Spinal Fusion Surgery without Bone Grafting<\/h2>\nDesign and object of a new 3D printed porous tantalum intervertebral fusion device.<\/figcaption><\/figure>\n
Spinal fusion surgery is a common treatment for spinal diseases, but it often requires bone grafting from the patient or a donor. This can cause complications such as infection, rejection, and pain. A team of orthopedic surgeons in China has developed a new solution: a 3D printed porous tantalum metal device that can fuse with the spine without bone grafting.<\/p>\nThe first lumbar spine clinical trial patient was a 55-year-old female patient who was admitted due to \u201clow back pain and numbness in left lower limb for 4 months\u201d. She was diagnosed with lumbar spondylolisthesis (isthmic fracture) and lumbar spinal stenosis. Professor Yang Cao led the team to successfully use the new 3D printed porous tantalum metal interbody fusion device to complete lumbar intervertebral body fusion surgery.<\/figcaption><\/figure>\n
The device is designed to mimic the natural structure and elasticity of bone, and to stimulate bone growth into its pores. This way, the device can achieve a close and firm attachment with the vertebrae, and avoid stress shielding and non-fusion problems that may occur with traditional materials such as PEEK or titanium alloy. The device also eliminates the need for a bone grafting chamber, which reduces the surgery time and cost.<\/p>\nThe first cervical spine clinical trial patient was a 54-year-old female who visited Wuhan Union Hospital Department of Orthopedics due to \u201cneck pain for 10 years, accompanied by pain, numbness and weakness in both upper limbs for 1 year\u201d. She was diagnosed with mixed cervical spondylosis.<\/figcaption><\/figure>\n
The team has successfully implanted the device in two patients with cervical and lumbar spine diseases, respectively. The patients recovered well and showed significant improvement in their symptoms. The team has applied for an invention patent and obtained a product registration certificate for the device. They plan to continue developing personalized 3D printed spinal implants that can benefit more patients with spinal diseases.<\/p>\nProfessor Yang Cao led the team to successfully use the new 3D printed porous tantalum metal interbody fusion device to complete microscopic assisted anterior cervical decompression fusion internal fixation surgery in 2 hours. The patient recovered satisfactorily after surgery and the spinal cord compression symptoms were significantly relieved. Six months later follow-up showed that the patient\u2019s symptoms were relieved and the porous tantalum metal interbody fusion device was stable.<\/figcaption><\/figure>\n
Case 2: A Novel Surgery Using 3D Printed Porous Vertebral Fusion Device for Spinal Cord Compression<\/h2>\n3D printed porous vertebral fusion device and supporting tools.It’s a personalized and innovative implant that can treat spinal cord compression without bone grafting. It has a porous and curved design that stimulates bone growth and integration, provides good stability and contact with the vertebral endplate, and restores the physiological curvature of the cervical spine.<\/figcaption><\/figure>\n
A patient with severe spinal cord compression due to cervical disc herniation underwent a novel surgery in Sichuan, China. The surgery involved removing part of the affected vertebra and implanting a 3D printed porous vertebral fusion device (artificial vertebra). This was the first time such a device was used in the southwest region of China.<\/p>\nThe patient, Mr. Liao, 63 years old, was admitted due to \u201cnumbness and pain in both upper limbs for half a year, aggravated for 2 months\u201d. Cervical MRI examination showed \u201ccervical 5\/6 intervertebral disc protrusion to the left and posterior, and downward free to the posterior of cervical 6 vertebra causing severe spinal canal stenosis, spinal cord compression edema\u201d.<\/figcaption><\/figure>\n
The device was personalized based on the patient\u2019s imaging data and designed to fit the shape of the vertebral endplate. The device had a porous structure that mimicked the natural bone and stimulated bone growth. The device also had a curved surface that increased the contact area with the endplate and avoided stress concentration. The device provided good stability, bone integration, and physiological curvature restoration for the spine.<\/p>\nDirector Chen Longyi and Deputy Director Liu Jinping\u2019s surgical team cooperated closely to perform anterior cervical vertebral subtotal resection, spinal canal enlargement decompression, and 3D printed porous cone fusion device (artificial vertebra) implantation for the patient.<\/figcaption><\/figure>\n
The surgery was performed by a team of neurosurgeons who cooperated with a technical team of medical 3D printing experts. The surgery went smoothly and the patient recovered well. The surgery was a new exploration of 3D printing technology in neurosurgery and a step towards precision surgery for spinal diseases.<\/p>\nThe surgery was successfully completed. Intraoperatively, the 3D printed artificial vertebra had good contact with the vertebral endplate, was firmly fixed, had sufficient bone grafting, and was easy to operate.<\/figcaption><\/figure>\n
Case 3: A Successful Revision Surgery Using 3D Printed Porous Artificial Acetabulum for Hip Joint Prosthesis Failure<\/strong><\/h2>\n
Mr. Luo, 60 years old, suffered from hip joint pain and limited mobility for a long time. He had an artificial hip joint implanted 20 years ago, but it was severely worn out and displaced, causing bone loss and spinal cord compression around the acetabulum. He needed a revision surgery to replace the damaged prosthesis and restore his hip function. He came to Chengdu First Orthopedic Hospital for help.<\/p>\nDirector Yin Yi\u2019s team used 3D printing technology to accurately print the patient\u2019s bone defect situation, and individually designed multiple surgical plans, performed computer simulation, and finally determined the 3D customized artificial prosthesis components.<\/figcaption><\/figure>\n
Director Yin Yi and his team from the Department of Joint Surgery decided to use 3D printing technology to assist in the surgery. They used the patient\u2019s imaging data to design and print a customized porous artificial acetabulum that matched the patient\u2019s anatomy and biomechanics. They also simulated the surgery on a computer and in vitro to ensure accuracy and smoothness.<\/p>\nMr. Luo\u2019s artificial hip joint was worn out abnormally severely. The artificial acetabulum had been \u201cworn through\u201d by the femoral prosthesis, and had shifted significantly, accompanied by a large amount of bone dissolution and bone resorption around the acetabulum.<\/figcaption><\/figure>\n
The team successfully performed the revision surgery with the 3D printed prosthesis. The prosthesis had good contact and stability with the bone, and stimulated bone growth and integration. The surgery restored the physiological curvature and function of the hip joint. Mr. Luo recovered well after the surgery and was able to walk and move freely.<\/p>\n

Conclusion<\/h2>\n
These cases show how 3D printing technology can create metal implants that are more compatible, stable, and functional than traditional methods. 3D printing technology can also reduce the risks of complications, infections, and rejection, and shorten the recovery time and cost for patients. Moreover, 3D printing technology can enable personalized design and simulation based on the patient\u2019s anatomy and biomechanics, ensuring a better fit and function of the implants.<\/p>\n
