Summary
Javelin throwers experience elbow joint damage, known as "javelin elbow," due to repetitive stress. Future research will assess if changes in throwing technique increase spinal and elbow injuries.
Area of Science:
- Sports medicine
- Orthopedics
- Biomechanics
Background:
- Javelin throwing involves repetitive, high-stress movements.
- Valgus stress at the elbow joint can lead to arthrotic alterations, termed 'javelin elbow'.
- The introduction of a new javelin in 1986 necessitates re-evaluation of injury risks.
Purpose of the Study:
- To analyze the relationship between javelin throwing mechanics and joint alterations.
- To investigate potential increases in elbow and lumbar spine injuries.
- To explore the incidence of spondylolysis and scoliosis in competitive throwers.
Main Methods:
- Observational analysis of javelin throwing biomechanics.
- Review of injury incidence in competitive javelin throwers.
- Assessment of degenerative changes in the elbow and lumbar spine.
Main Results:
- Repetitive valgus stress at the elbow causes arthrotic changes ('javelin elbow').
- Increased explosive force from the new javelin may elevate injury rates.
- Further study is needed to confirm links between throwing and spinal issues.
Conclusions:
- Javelin throwing poses significant risks for elbow joint degeneration.
- The biomechanics of javelin throwing may contribute to lumbar spine pathologies.
- Ongoing research is crucial to understand and mitigate these sports-related injuries.
