Learning About Stress Fractures
Noel Gressner, Physical Therapist at Miami Orthopedics and Sports Medicine Institute, explains spondylolysis and spondylolisthesis are terms to refer to a certain area of the spine of the vertebral column that would be fractured. He says it is like an extension and rotation type of mechanism of injury repetitively happening to what's called the pars interarticularis.
According to him, stress fracture can progress into a full-blown fracture and it can also progress into both sides.
