To measure the Cobb angle on scoliosis, x-ray has been the common tool for decades. For teenage girls with idiopathic adolesent scoliosis, the increased exposure to radiation from x-ray can increase their risk of developing breast-cancer or becoming infertile. It is estimated that girls will have an average of 22 x-rays during a three year treatment period. In an attempt to mitigate this risk, radiologists take the x-ray in the posteroanterior position which reduces the risk somewhat. New x-ray systems have also been developed to help reduce the radiation risk further.
In some countries, school based screening programs are in place to assess for scoliosis in children and teenagers. In the US, where these programs are mandated in some states, the value and cost effectiveness is often debated. As scoliosis is a three dimensional deformity, it is important to be able to measure the spine in all three planes, which is why x-ray is a popular choice, however, this also drives cost.
The EasyAngle Digital Goniometer is an effective tool for measuring range of motion of the spinal column in all three planes. EasyAngle can measure the cobb angle on scoliosis in just two clicks. As such, it can be used to reduce costs for school screening programs. As well as measuring the cobb angle, the EasyAngle also performs the same function as a scoliometer, where the patient can fold forward while the device is moved along the spine to assess for deformities. Kyphosis and lordosis angles can also be easily measured using EasyAngle.
