Medanta: Indian surgeons successfully implant 3D printed vertebrae in a 32-year-old woman
The team of surgeons led by Dr. V Anand Naik, Senior Consultant Spine Surgery, Bone & Joint Institute from Medanta - The Medicity, Gurugram replaced the damaged vertebrae with a 3D printed titanium vertebrae - to bridge the gap between the first and fourth cervical vertebrae.
As a pending history of infertility, the patient suffered tuberculosis due to high intake of steroid (by quakes) which lowered her immunity to a level where the patient developed TB at 10 different vertebrae in the spine. The first, second and third cervical vertebrae were severely damaged up to an extent that there was no skeletal support available between skull and lower cervical spine (there was disconnect between skull and lower part of the spine) due to which the head was sliding forward and curved in such a way which was causing obstruction to the spinal cord which was causing progressive weakness in all the limbs – inching towards quadriplegia; compression of the respiratory nerves and eventually death.
This 10-hour long surgery is the first of its kind for reconstruction with 3D printed vertebrae in India and probably third in the World, following similar surgeries that were conducted in China and Australia for different parts of the spine.
Dr. V Anand Naik, said, "it was a very complex surgery and the patient's condition was deteriorating each day. It would not have been possible to do it without a 3D printing technology."
"It is comparatively an effective method of surgery since everything is planned before, and also a new dimension to complex spine reconstruction in difficult anatomy and complex Tumors and infections," he added.
Shedding more light on the treatment process, Dr Gopal Kumar, Consultant, Head & neck oncosurgeon at Medanta-The Medicity said,” The challenge for our team was to reach high into the neck without altering the position of the patient. Anterior approach, small working field, in cases such as these is not basis one’s choice but a necessity. Patient being a singer, preservation of laryngeal nerve was of prime importance. Swallowing, chewing and movement of tongue, all was at risk. After mobilisation and retraction of larynx and oesophagus space was created for Dr. Anand to work and perform the implant.”
Dr. SKS Marya, Chairman, Institute of Bone & Joint, Medanta-The Medicity said, “Medanta believes in constant innovation in Medical technology and Healthcare practices. The outcome of the surgery clearly demonstrates our commitment towards improving the standards in patient care. Our team of doctors have introduced a path breaking solution in a complicated case such as this. They have worked very hard and we are extremely happy with the results as the patient is gradually moving back to normalcy.”
Dr. Naik and his team used an intricate computer software to plan every detail of the operation. The titanium cage was customised according to the patient’s original spine. The high-resolution CT & MRI scans of the patient spine were uploaded on the software and a dummy of the patient’s spine was 3D printed to measure the gaps & surgical resection between the first and the fourth cervical vertebrae. Finally, the 3D titanium implant was printed, which was to be placed in the body. The printed 3D titanium vertebrae were further tested for biomechanics and stress risers post receiving inputs from design team in India, Sweden and USA. The standard time to plan and perform the surgery is between three to four weeks. Dr. Naik (Spine) & Dr. Kumar (Head & neck) at Medanta The Medicity, effectively planned the approach and executed the complex upper cervical spine surgical approach and reconstruction, within a week, in a much lesser time citing the emergency of the case.
The patient who is a teacher by profession is recovering fast with newly reconstructed cervical vertebrae. She has recovered from all her weaknesses & radiculopathies in Upper and Lower limbs within 4 days of surgery and is now able to walk. She will be able to lead an independent pain & risk-free life in 2 weeks.
Dr. Naik and his team are now looking forward to a long term result and a decent independent lifestyle for the patient.
