Low back pain in adolescents is a frequent reason for consultation in rheumatology and is due to different causes. A clinical case of a 14-year-old adolescent from rural origin who comes to the clinic reporting pain and volume increase in both knees of three months of evolution accompanied by low back pain of more than two years of evolution that had required treatment is presented. with non-steroidal anti-inflammatory drugs and rest, without other accompanying systemic symptoms, physical examination revealed knee arthritis, increased physiological kyphosis in the thoracic spine and positive sacroiliac points. In the complementary tests, the presence of HLA-B27, synovitis in the bilateral sub quadriceps bursa on ultrasound of the knees, findings in the radiographs at the level of the bodies of the lumbar vertebrae characteristic of Scheuermann’s disease, and sclerosis of both sacroiliacs’ characteristic of juvenile idiopathic arthritis, it is concluded that the patient suffers from two conditions, which by different mechanisms cause low back pain.
