Types of fractures are divided into two kinds , one for closed fracture , the other for open fractures . This includes two transverse fracture morphology of fracture , oblique fracture , spiral fracture, compression fracture , rupture fracture, fracture, crack fracture, dislocation fractures. To the patient's chief complaint ( pain, swelling, bone fracture and deformation sound ), and X-rays as a diagnostic . Cases of fracture , because fracture caused by external forces , after the first X-ray examination can not correctly interpret and judge the case caused a miscarriage of justice , do not select the right treatment , and later will lead to poor healing , muscle atrophy, joint stiffness , the length of the foot , such as the aftermath of surgery , the result of repeated surgical treatment , not only time-consuming , laborious, and more waste of medical resources. Therefore we use the histogram to strengthen against the suspected fracture site to positive , flip , crop, capture and formalize the corresponding parts of the normal bone ; normal bone and suspected fractures after normalization with Gaussian smoothing noise ; Sobel filter operands do edge detection , capture edges ; do Morphing normal bone image distortion image processing ; then do the normal bone deformation and fracture site normalization balanced brightness brightness average ; followed by normalization with normal bone fracture site deformed two images do subtraction processing ; Finally, we use a threshold to strengthen the image binary edge image to highlight the position of the mutation to provide important information to be physicians to observe whether the fracture symptoms occur. The study period in the future could help physicians quickly correct interpretation of the fracture X-rays , so that most cases of fracture of the right to accept and appropriate surgical treatment.
