WFMY -- Doctors called Jaxx Denny's surgery on Tuesday a huge success.
Four months ago, doctors rebuilt Jaxx's ribcage and straightened his S-shaped spine, using four metal rods.
Jaxx, now 15 months old, has been growing so fast that doctors had to expand the rods to grow with him.
On Tuesday, they expanded all four rods and literally stretched him out.
Doctors also told Pete and Tammy Denny that Jaxx's right lung is growing, now that there is room for it to grow. His right lung is almost the same size as his left lung.
Pete Denny said Jaxx should able to go home on Wednesday.
They thanked everyone for praying for little Jaxx.
