The investigated group comprised 207 patients treated at the spondylologic consulting centre of the orthopaedic clinic where 576 assessment were made with subsequent computer evaluation. Mathematically the correlation between the angle of the costal hunch assessed by a scoliosometer and Cobb's angle on the X-ray picture was calculated. The value of the correlation coefficient was 0.8049. For statistical processing of the results of measurements the authors used the method of robust regression and an equation was calculated according to which the prediced values of Cobb's angle Y were calculated. These results were listed in a table for the extent of measurements from 1 to 16 on the scoliosometer which corresponds to idiopathic scoliosis grade 1 and 2. The scoliosometer is a pendular gravitational instrument which can be replaced by a plummet suspended on a protractor. Assessment of the costal hunch by a scoliosometer can partly reduced check-up examinations of scolioses by X-ray examination of the spine. Key words: scoliosis, scoliosometer, assessment of the costal hunch.
