ABSTRACT. Roentgen stereophotogrammetry is a new method for short term analysis of growth rate. Growth is measured over the growth zone in the distal fibula and is a fraction of the total statural growth. Normal growth rate in the distal fibula is about 15 μm/day at a total growth rate of 5 cm/year. The method was used to follow growth six months before and six months after surgery in six growth retarded children with Crohn's disease. Growth rate increased significantly ( p <0.01) within three months after surgery from 5.8 μm/day before operation to 15.8 μm/day three months after operation and six months postoperatively had reached 18.0 μm/day. Improved growth could be recorded as early as four weeks after operation. The Roentgen stereophotogrammetric analysis (RSA) gives a unique possibility to follow short‐term changes in growth rate in children with disturbed growth and to use growth rate as a quick assessment of response.
