A REVIEW OF FOREIGN LITERATURE ON INSTABILITY OF THE LUMBAR SPINE
Spinal instability is a pathological condition, which is based on the mechanical displacement of the vertebrae relative to each other, accompanied by pain in the corresponding region of the spine. This pathology is often the determining factor in establishing the indications for surgical stabilization of the vertebral-motor segments. Although instability of the lumbar spine, has been discussed in literature it still hasn't been sufficiently studied.
