using a tuning fork to test for lower leg fractures
- Test types
- provocation of pain
- sound conduction
- 128 Hz (256 and 512 Hz also described)
- Vibratory irritation at damaged periosteum
Clinical value of tuning fork test
- sensitivity questionable → poses a problem with use of tests for screening purposes
- may not aid in ID of fracture with mineralized callus
- better ID of transverse fractures than other fracture types
- less accurate for stress fractures
- bone shell more intact in earlier stages
Ultrasound
- Methodology
- provocation of pain
- heat absorbed at damaged periosteum
- Clinical Value
- negative LR and sensitivity questionable → poses a problem with use of tests for screening purposes
