Abstract
Detection of fractures of a bone is still a problem among orthopaedic doctors. Different types of techniques used for the detection of the fracture are discussed here. Two novel sonic diagnostic techniques based on stress wave propagation and shift in resonance of the bone are developed. These techniques are found very useful in the diagnosis of the size and site of a fracture as well as its rate of healing. The techniques are quick, reliable and safe for both the patient and the operator.
