An aetiological study on spondylolysis from a biomechanical aspect
British Journal of Sports Medicine
|September 1, 1982
Summary
Over 60% of athletes experience lumbago, with 27% developing spondylolysis. Biomechanical analysis indicates that the type and direction of loads significantly influence spondylolysis incidence in athletes.
Area of Science:
- Sports Medicine
- Orthopedics
- Biomechanics
Background:
- Lumbar disorders are prevalent in athletes.
- Understanding the biomechanical factors contributing to these injuries is crucial for prevention and treatment.
Purpose of the Study:
- To investigate the clinical presentation and incidence of lumbar disorders in athletes across different sports.
- To determine the relationship between specific sport-related biomechanical loads and the development of spondylolysis.
Main Methods:
- Clinical assessment of lumbar disorders (symptoms, X-ray findings) in athletes from various sports.
- Categorization of sports based on primary lumbar load.
- Biomechanical laboratory analysis using human cadaveric specimens subjected to axial compression and rotational bending.
Main Results:
- Over 60% of surveyed athletes reported "lumbago" (low back pain).
- Spondylolysis was diagnosed in 27% of athletes with lumbago.
- Biomechanical testing demonstrated that the extent and direction of applied loads correlate with spondylolysis incidence.
Conclusions:
- Athletes are at high risk for lumbago and spondylolysis.
- Specific biomechanical forces experienced during athletic activities are key determinants in the development of spondylolysis.
- Further research into sport-specific load management is warranted to reduce injury rates.
