Spondylolysis occurs mostly at L5 (80-95%). There is increased prevalence in specific ethnic, sports and family groups. The young athletic population has a spondylolysis more frequently. There is an increased risk in gymnasts, football players, cricketers, swimmers, divers, weight lifters and wrestlers. | Spondylolysis occurs mostly at L5 (80-95%).

Definition/Description[edit | edit source]
Spondylolysis is a unilateral or bilateral bony defect in the pars interarticularis of the vertebra. The term derives from the Greek words spondylos (vertebra) and lysis (defect). [1][2]

Epidemiology /Etiology[edit | edit source]
Spondylolysis affects 3-6% of the population.[1][2][3] This condition appears in the first or second decades of life, the frequency of spondylolysis increases with age until 20 years. There is no change in prevalence with increasing age from 20 to 80 years old. Men are affected two times more as women.
Spondylolysis occurs mostly at L5 (80-95%). There is increased prevalence in specific ethnic, sports and family groups. The young athletic population has a spondylolysis more frequently. There is an increased risk in gymnasts, football players, cricketers, swimmers, divers, weight lifters and wrestlers.
Spondylolysis is considered to be a stress fracture that results from mechanical stress at the pars interarticularis. These stress fractures occur due to repetitive load and stress, rather than being caused by a single traumatic event. The stress distributions at the pars interarticularis are the highest in extension and rotation movements. There is a possible genetic tendency for people with lower cortical bone density at the pars interarticularis.
