Hi, Today we will talk about the use of ultrasonography in bone fractures I am Mehmet Ali Aslaner, Emergency Medicine Specialist. Love from Cappadocia. Since children and pregnant women are considered radiation sensitive groups, minimum exposure is important for these patients Ultrasonograhy easily can be used instead of X-ray for the diagnosis of fracture If an X-ray was taken and fracture diagnosis still is not clear, It can be used to confirm the diagnosis It is also a very convenient method to evaluate the success of the reduction and environmental aspects. Linear probe is the most commonly used probe in musculoskeletal system Convex probe can also be used according to the condition of the patient In recognition of bony structures, it is enought to recognize the cortex If you can not see anything behind the well-constructed hyperechoic line, you can call it “bone cortex” You need to follow the cortex line to detect fracture Any deterioration and stepping should lead us to a suspected fracture Nasal scans should be performed on top as well as both sides You are more likely to catch lateral fissure fractures that you can skip. Although the fracture diagnosis is sometimes obvious, it is important that the fracture damage which tissues For example, a clavicle fracture may cause artery or ven injury Although the hematoma area is seen around the fracture in this patient, the artery-vein structures appear stable at a certain distance from the fracture Especially protecting the pediatric patient group from radiation has been the subject of study for many physicians Wrist fractures can easily be recognized with the US Recognition of sono anatomy is necessary for accurate diagnosis In this image, radius fracture is seen In case of suspected broken wrist, both Radius and Ulna should be scanned in 3 directions Fractures are most commonly found on dorsal scans In this image, the fractured line is not clearly seen on the volar and lateral scans, whereas the dorsal scan shows cortex irregularity. Epiphysis can be confusing, especially in childhood An epiphyseal line is seen in the view after the broken line. If you can not distinguish between a fracture and an epiphyseal line, the easiest way to do it is to view the other limb of the patient. The age-specific graphs for the epiphysis line are shown here The epiphyseal line is not observed after 18 years of age. US can be used for elbow fractures with 98% sensitivity and 70% specificity , and reduced unnecessary graph request by %48 The use of US in radial fractures reduces recurrent reduction rates and decreases surgical rates. Ankle, more complex than wrist, is easily scanned by US in isolated trauma. To summarize; Ultrasound reduces unnecessary radiological imaging rates and reduces reduction rates in fractures.
