Spondylolysis and Spondylolisthesis

The chapter delves into a comprehensive examination of both diagnosis and treatment strategies for spondylolysis and spondylolisthesis. Spondylolysis, a condition characterized by defects or fractures in the pars interarticularis, presents a significant concern in both general and athletic populations. Spondylolysis warrants careful consideration with an incidence ranging from 3% to 10% in the general population. The prevalence of spondylolisthesis varies across age groups, with a notable presence in athletes experiencing persistent back pain, particularly those engaging in activities placing repetitive stress on the lower spine, such as gymnastics or weightlifting. Spondylolisthesis, often referred to as listhesis, describes the displacement or slippage of a vertebral body in relation to its adjacent counterpart. This displacement can occur either forward (anterolisthesis) or backward (retrolisthesis). It is more commonly found in athletes, especially those experiencing persistent back pain (most commonly observed at the L5-S1 level), with rates reaching up to 50%. Conservative treatment is typically the first line of approach, prioritizing noninvasive methods such as physical therapy and pain management. However, surgical intervention may become necessary if athletes experience persistent, chronic pain or if there is evidence of worsening vertebral displacement over time.
