Degenerative spondylolisthesis at L4 is associated with which conditions?

Degenerative spondylolisthesis happens when aging changes in the lumbar spine—disc and facet joint degeneration—let the vertebra slip forward, most often at L4–L5. That forward shift narrows the spinal canal, leading to central canal stenosis and irritation or compression of the nerve roots. The resulting symptoms are classic neurogenic claudication—leg pain or numbness that appears with walking and improves with rest or bending forward. This direct link between the degenerative slip and canal narrowing with claudication is why this option is the best fit. The other options point to different problems: a pars interarticularis fracture and spondylolysis describe isthmic spondylolisthesis, typically in younger individuals, not the degenerative type, and scoliosis can occur but is not the defining association here.
