Introduksjon: Ved å bruke 3D-utskriftsteknologi for å produsere titanlegeringsimplantater for å erstatte menneskelige bein, har det vært mange tilfeller i Kina, inkludert hofteledd, ryggrad, brystben, osv. Så hvordan gjør India fremgang på denne fronten?
10. februar 2022 fjernet en kompleks operasjon ved Manipal Hospital i India kreft fra en pasient og rekonstruerte brystbenet og ribbeina ved hjelp av 3D-trykte titanlegeringer. 50-åringen fra Bangladesh har en sjelden og kompleks kreftsykdom som påvirker brystbeinet og de første åtte ribbeina på venstre og høyre side. Selv om kreften kunne fjernes kirurgisk, var det ingen levedyktig løsning for å immobilisere brystbenet og ribbeina, som er kritiske for normal pust.
Dr. Somashekhar, Chairman and Chief of Oncology Surgery at Manipal Hospital, said: "Advanced technologies are now available to provide treatment for complex cancer cases that were otherwise considered incurable by many. The credit for this case goes to Manipal Syndrome. The excellent coordination between the cancer center and the plastic surgery department, which has experts in modern technology and medicine, brings hope to millions of cancer patients worldwide."

en spesielt kompleks operasjon
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 surgery, the surgeon performed a CT scan of the patient area, created a personalized 3D model of the desired implant, which was 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".

After the operation, the patient recovered smoothly, and after physical therapy of 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 patients' 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 parts of the bone have 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 of a combination of excellent medical care and technology."
