OBJECTIVE: Clinical characteristics of @entity85 that commonly occur in @entity1 with @entity1152 ( @entity1152 ) are unclear. The objective of this study was to assess the incidence and natural history of @entity154 and @entity1635 in @entity1 with @entity1152 . METHODS: A population-based cohort of 100 adults who had an operation for @entity1152 in our hospital were examined clinically and radiographically for @entity85 . The results were compared with data obtained from normal population-based controls. RESULTS: @entity3574 were observed in 45 @entity1 , predominating in the cervical spine in 38 @entity1 . Any additional anomaly was the most significant risk factor (odds ratio [OR]: 27 [95% confidence interval (CI): 8-100]) for the occurrence of @entity3574 . Scoliosis of >10 degrees was observed in 56 @entity1 , >20 degrees in 11 @entity1 , and >45 degrees in 1 @entity1 . The risk for @entity1635 of >10 degrees was 13-fold (OR: 13 [95% CI: 8.3-21]), and the risk for @entity1635 of >20 degrees was 38-fold (OR: 38 [95% CI: 14-106]) compared with those in the normal population. Thoracotomy-induced rib fusions (OR: 3.6 [95% CI: 0.7-19]) and other associated anomalies (OR: 2.1 [95% CI: 0.9-2.9]) were the strongest predictive factors for @entity1635 . The general clinical course of @entity85 was mild, and none of the @entity1 had undergone spinal surgery. CONCLUSIONS: The risk of @entity1635 is 13-fold after repair of @entity1152 in relation to general population. Nearly half of the @entity1 have @entity3574 predominating in the cervical spine. Most of these deformities were not diagnosed primarily or during growth. Spinal surgery is rarely indicated.
