HAMSTRING STRAIN

Rheumatology

HAMSTRING STRAIN

1. Commonly occur with forceful eccentric contraction of the hamstring muscles, especially when the muscle is at a mechanical disadvantage near full flexion or full extension.

2. Can be reproduced by passive stretch of the muscle, resistance testing of the muscle, direct palpation of the injured area.

3. Severe hamstring strains will produce visible ecchymosis at and distal to the site of injury.

4. Management - rest (6 weeks if severe), ice, analgesia, gentle ROM & strengthening exercises.

5. Complications - ischial avulsion fracture is common in 15-25yrs of age. May require surgery if very displaced, non-union occurs or in high-performance athletes.
