Résumé

BACKGROUND: Several reports have suggested low bone mineral density (BMD) in patients with adolescent idiopathic scoliosis (AIS). We determined bone mineral status in patients with AIS to evaluate the effect of brace treatment on BMD. METHODS: BMD was measured in 46 patients (mean age, 17.8 +/- 4.9 years) with AIS (17 with brace and 29 without brace) by dual-energy X-ray absorptiometry scan and compared the results to an age-matched (mean age, 16.6 +/- 3.9 years) control group (n = 54). RESULTS: The AIS group had significantly lower bone mass at the lumbar spine (Z-score, -1.500 vs. -0.832) and hip (Z-score, -1.221 vs. -0.754) except at the femoral neck. No difference in BMD was found between patients with AIS who used a brace and those who did not. CONCLUSIONS: The results confirmed that BMD was low in AIS patients and it was not affected by brace treatment.

Résumé

Congenital scoliosis occurs because of either the failure of formation or the failure of segmentation or both. Evaluation of the incidence and the types of occult intraspinal abnormalities in congenital scoliosis is the subject of this study. During a period of 29 years, 103 patients with congenital scoliosis were studied. MRI was used in 46 patients, myelography or CT myelography was used in 64 patients and both MRI and myelography or CT myelography were used in 7 patients for intraspinal abnormalities. In the MRI group, among the 46 patients, 19 patients [41.3%] had intraspinal abnormalities consisting syringomyelia in 9 [19.5%] diastematomyelia in 8 [17.4%], tethered cord syndrome in 6 [13%], low conus in 5 [10.8%] and diplomyelia in 3 [6.5%] of the patients. In the myelography group, among the 64 patients, 17 [26.5%] had intraspinal abnormalities and diastematomyelia was the most common one found in 14 [21.8%] patients. Intraspinal abnormalities are frequent in congenital scoliosis. Syringomyelia may be associated with congenital scoliosis. In congenital scoliosis, rib fusion may be an indicator of intraspinal abnormalities in MRI. A significant difference between clinical findings and intraspinal anomalies [P<0.05] was noted. Moreover, we believe that total spinal MRI with coronal, sagittal and axial views is a valuable tool in determining the intraspinal abnormalities in congenital scoliosis. This method is highly recommended for detection and neurosurgical intervention before corrective surgeries.
