In earlier days to operate on the lungs and heart, the chest had to be spread open by cutting the skin all along the back and then spreading the ribs apart. This caused a lot of pain to the patients after the surgery. But in the modern era, due to improvements in technology, we can now operate on the chest with small cuts (2-3 cm) and without spreading or cutting the ribs. It leads to a pain free experience and early discharge from the hospital and avoids large scars.
