use3D printingTechnology to manufacture titanium alloy implants to replace human bones, there have been many cases in China, including hip joints, spine, sternum and so on. So how is India progressing on this front?
On February 10, 2022, a complex operation was carried out at Manipal Hospital, India.
Operation
successfully removed the cancer from the patient, and utilized3D printingTitanium reconstructed his sternum and ribs.
The 50-year-old from Bangladesh has a rare and complex cancer that affects his breastbone and the first eight ribs on the left and right. Even if the cancer could be surgically removed, there was no viable solution to immobilize his sternum and ribs, which are critical for normal breathing.

Chairman and Director Dr. Somashekhar said: “Advanced technology is now available to provide treatment for complex cancer cases that many would otherwise consider incurable. The credit for this case goes to the partnership between Manipal Comprehensive Cancer Centre and the Department of Plastic Surgery. excellent coordination between modern technology and
medicine
Experts in the field, bringing hope to millions of cancer patients around the world. “
a particularly complex operation
The patient was taken to Manipal Hospital, where his MRI showed a 15 x 12.7 cm tumor mass over his lungs and heart that had destroyed the length of the patient’s sternum and the inside of his ribs.Before the operation, the surgeon performed a CT scan of the patient area for the required
Implants
A personalized 3D model was created and then 3D printed in titanium.
Someshekhar explained, “We 3D printed a new titanium sternum, custom-made for this patient based on his size, height, weight and the part of the bone to be removed, and we worked with the company’s technologists, engineers and Manipal Oncology Surgery and The plastic surgery team held several meetings”.
The patient underwent tumor removal surgery and his entire sternum and ribs were removed without much blood loss. This area was then replaced with a custom-made titanium alloy implant, which was held in place using new drilling techniques and titanium wire. Finally, before the skin is sutured, the implant is covered with a muscle flap removed from the patient’s chest to restore normal breathing function.
Someshekhar continued: “The implants are often very heavy, up to 5kg, which is too heavy for the patient to carry on the chest. To correct this, we used a modified honeycomb technique to keep the weight of the sternum and sternum below 250 grams”.
full recovery
After the operation, the patient recovered smoothly, and after physical therapy on the chest, he was able to move gradually. During his discharge from the hospital, he was reported to be able to eat, breathe and walk normally without any complications.
According to Dr. Ashok, Consultant Plastic, Reconstructive and Aesthetic Surgeon at Manipal Hospital, 3D printed implants offer a number of important benefits for patient recovery.
“The implants are strong, durable and lightweight,” he said. In addition, they are well received by the body and are less prone to immune responses and implant rejection. The implants reduce osteoporosis disease, as well as the risk of fracture around the implant due to uneven stress transfer between the implant and surrounding bone tissue”.
The successful placement of 3D-printed titanium alloy implants means that after the tumor and affected part of the bone has been removed, the patient no longer has to permanently rely on mechanical ventilation to breathe.
“New-age technologies and materials are helping patients with complex problems get resolved and recover quickly,” Ashok added.
“This patient is a perfect example, excellent

Service and technology come together. “
