NEW DELHI: Till a few years ago, deformities in patients' limbs were corrected using traditional methods. These were based on Ilizarov fixator and involved cutting the bone (osteotomy), correcting the angle and fixing it with plates and screws, followed by a plaster cast. But this process was time-consuming and prone to errors. In many cases, it turned out to be not as accurate as expected. Now, with the increasing use of technology, artificial intelligence-assisted “six-axis” systems are working on multiple deformities simultaneously. The software-assisted method takes less time for the procedure and is also more accurate, doctors said. Recently, Aisha, a teenage girl who suffered from bow legs (also known as “crooked legs”), underwent a corrective surgery at a private city hospital. The surgery was performed using an external fixator based on a hi-tech six-axis system. Doctors in the city say the new and improved six-axis correction system is “revolutionary” and should be made available to more people. They say the method, which is currently available only in some private facilities, should be introduced in public hospitals as well. “In the traditional way, if a deformity had to be corrected, it could only be done in two dimensions. For example, if one person had multiple bone deformities, they had to be corrected one by one and the doctor had to do all the work, from calculating the angles to applying them manually. But now we have six-axis correction software, which is a hexapod with six legs that can move in any direction,” said Dr Manish Dhawan, senior deformity correction surgeon at Sir Ganga Ram Hospital. “Doctors had to be very precise while doing the 2D correction. If not done properly, it can lead to a different deformity as the bones move in different directions,” he added. Explaining how the six-axis technology works, Dr Gaurav Prakash Bhardwaj, director of sports injuries, joint preservation and replacement surgery at PSRI Hospital, said, “You make an incision in the bone and place an external device like a hexapod on it. The software calculates and determines the frequency and angle of alignment.” Dr Dhawan said there was a need to create awareness about this new technology, saying, “This technology is expensive and specialized, so it is being done only in a few places now. But we need to encourage its widespread use.” According to Dr Bhardwaj, “Most cases of bone deformity occur among people from low-income groups who usually cannot avail the help of new technology. Government hospitals should use it to correct deformities.”
