When chronic pain from a spinal compression fracture persists despite rest, activity modification, back bracing, and pain medication, surgery is the next step. The L3-L4 spinal motion segment, positioned in the middle of the lumbar spine, plays an important role in supporting the weight of the torso and protecting the cauda equina (nerves that descend from the spinal cord). You can shorten your recovery by maintaining a proper lifestyle and cooperating with your doctor. The point at which superior and articular facets meet is known as a facet, or zygapophyseal, joint. Compression fractures of the L1 vertebra are relatively rare, accounting for less than 5% of all vertebral fractures. While the C7 vertebra is similar to C6, it has a few unique features:A lumbar disk replacement is a type of back or spine surgery. Fractured vertebrae are usually caused by osteoporosis and traumas like falls, sports. These discs allow the spine to move freely and act as shock.
