Bone fracture is a common problem in daily life which occurs when high pressure is applied on bone or by simple accident and also due to osteoporosis and bone cancer. Different techniques are used today to detect bone fractures such as X-Ray, Computed Tomography (CT-scan), Magnetic Resonance Imaging (MRI) and Ultrasound. Among these four modalities, X-ray diagnosis is commonly used for fracture detection. However, if the fracture is complicated, a CT scan or MRI may be needed for further diagnosis and operation. In this paper, it is intended to make a low-cost portable device for bone fracture detection of patients, having age between 15 to 45 years using sound waves generated by the vibrator of a mobile phone. FFT technique in MATLAB was applied to the generated sound waves to examine the difference between cracked and healthy bone by applying 200 Hz of the sampling frequency. The device will be useful for doctors and public alike since it is portable, practical, mobile and affordable. It must be noted that the proposed device is not intended for a replacement of standard methodologies like X-Ray but rather will serve to be used as an initial detection phase. It is hoped that a negative scan of this device will discount the need for the more costly and timeconsuming X-Ray procedure.
