- Damaged vertebrae replaced with 3D-printed titanium vertebrae
- First such surgery in India using 3D-printing technology, third in world
- Woman can walk again after bout of disabling spinal tuberculosis
The team of surgeons 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.
“Given the complexity of this case, the use of 3D-printing technology has helped us in bringing a successful outcome. The patient today on 12 post-operative days is now walking with minimal support, all her pain has gone, her voice and dysphasia has recovered completely and, most importantly, her life was saved by this technique,” Dr V Anand Naik, Senior Consultant (Spine Surgery), Bone & Joint Institute at Medanta who led the team of surgeons, told IANS.
“This is the first such surgery in India and probably third in the world by using 3D-printing technology. These techniques have opened a new avenue wherein any type of complex reconstruction can be done in the spine with less collateral damages,” Dr Naik added.
The first, second and third cervical vertebrae were severely damaged up to an extent that there was no skeletal support available between the skull and the lower cervical spine — a disconnect between the skull and lower part of the spine.
It resulted in progressive weakness in all the limbs and increased the risk of quadriplegia, a condition linked to compression of the respiratory nerves that could lead to death.
The titanium cage was customised according to the patient’s original spine.
Finally, the three-dimensional 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 after receiving inputs from design teams in India, Sweden and the US, Medanta said.
The patient is now recovering fast with the newly-reconstructed cervical vertebrae, according to the doctors.
“We are extremely happy with the results as the patient is gradually moving back to normalcy,” said S.K.S. Marya, Chairman, Institute of Bone & Joint at Medanta.
The patient is expected to lead an independent risk-free life in about two weeks, according to the doctors.
