Spontaneous Correction of Sagittal Imbalance After Isolated Lumbar Decompression

Sagittal spinal imbalance may be caused by orthopedic problems, compression of the neural structures of the spinal canal, and pain syndrome (functional imbalance). Sagittal imbalance in combination with appropriate clinical symptoms may require surgical correction of the spine with fixation. However, in some cases, patients experience spontaneous correction of sagittal balance after isolated decompression without any correction or fusion. Therefore, it is necessary to clarify whether isolated decompression may cause spontaneous correction of sagittal imbalance in patients with degenerative lumbar stenosis.
