The tuning fork test is a really handy tool but only is useful in superficial fractures for suggesting a likelihood of a fracture e.g. on fingers or metatarsals. So to are srpin tests of the bone and even therpeutic ultrasound to diagnose the fracture e.g. it will elicit pain over the fracture site. Not sure any of that will help with an older injury and one whose issue now is the recurrent bruising. But thanks for mentioning the test as I use it all the time.
