BACK PAIN IN ADOLESCENT PATIENTS WITH ADO LESCENT IDIOPATHIC SCOLIOSIS (AIS)

Current knowledge on the association between back pain and idiopathic scoliosis is often contradictory. The presence, localisation and impor tance of pain was evaluated for a cohort of 426 adolescents with AIS. Patients were recruited from a scoliosis clinic in a pediatric hospita l. A questionnaire and an analogue visual scale graduated from 0 (no p ain) to 100 (maximal pain) were used in order to verify more precisely , the importance of the association between AIS and back pain. Chi-squ are, linear regression and Student T-test were used for statistical an alysis. 239 patients with right thoracic and left lumbar curves (RTLL) had a prevalence of pain of 54%. The mean of maximum pain intensity w as 49 mm +/- 20. No relation was found between the severity of the sco liosis and back pain. The two groups (with and without pain) were comp arable. Cobb angles were about the same for the thoracic and lumbar re gions, as well as kyphosis and lordosis, weight, height and age. Risse r sign, sex, brace and pelvic tilt were the only variables associated with pain (p<0.0001). Association between AIS and pain is more frequen t than generally reported. Pain appears to be more related with pelvic tilt than severity of the scoliosis.
