Spondylolysis
| Classification according to ICD-10 | |
|---|---|
| M43.0 | Spondylolysis |
| ICD-10 online (WHO version 2019) | |
As spondylolysis or spondylolysis the interruption of the pars interarticularis (interarticular, the area between the upper and lower articular process) in the sheet usually of the fifth (80% of cases) or fourth refers to lumbar vertebrae (15% of cases).
causes
There is a genetic predisposition, whereby the spondylolysis is never present at birth, but develops afterwards. Traumatic pathogenesis is also possible. Children who do sports that involve frequent reclining (backward bending), such as gymnastics or butterfly swimming , are at increased risk.
Spondylolysis occurs more frequently in patients with cerebral movement disorder and flexion contractures. There is an association with Scheuermann's disease and Marfan's syndrome .
frequency
After the end of growth, it is found at 7% of the population.
clinic
As a rule, spondylolysis does not cause any discomfort; if so, then when the trunk is tilted backwards.
As a result of spondylolysis, the mobility of the vertebral segment is increased, which can lead to asymmetrical growth of the base and cover plates and thus to the development of vertebral sliding (spondylolisthesis). In rare cases, spondylolysis leads to the vertebral body slipping off completely (spondyloptosis).
