Neuromuscular scoliosis had been approached as a spinal deformity for long time without considering the ribcage geometry/shape for breathing. Esthetical correction through surgery in neuromuscular scoliosis is not a complete solution, a corrected spine with a deformed ribcage will not improve the function of the lungs. Treatment approach for the ribcage is a must if we are looking for a functional treatment. For this reason, I decided to research in the geometrical evolution of the neuromuscular scoliosis compared with idiopathic scoliosis, to see the resembles and differences. Reverse modelling of the ribcage proofed to be a good treatment with results in the esthetic of the spine. The spine it seems to follow the ribcage evolution. For this reason, the big question is that maybe the deformity of the spine is the result of the ribcage collapse.
