OBJECTIVECervical sagittal alignment (CSA) is related to function and quality of life, but it has not been frequently studied in patients with adolescent idiopathic scoliosis. This study aimed to reveal the change in CSA following corrective surgery, compare the cervical sagittal parameters according to curve types, and assess related factors for postoperative aggravation of CSA.METHODSThe authors studied 318 consecutive patients with adolescent idiopathic scoliosis who underwent corrective surgery at a single center. Occiput–C2 and C2–7 lordosis, C2–7 sagittal vertical axis (SVA), T-1 slope, thoracic kyphosis, and lumbar sagittal profiles were measured preoperatively and postoperatively. Scoliosis Research Society Outcomes Questionnaire (SRS-22) scores were used as clinical outcomes. Each radiological parameter was compared preoperatively and postoperatively according to curve types (double major, single thoracic, and double thoracic curves). Patients were grouped based on preoperative CSA: the lordotic group (group L) and the kyphotic group (group K). Each radiological parameter was compared between the groups. Related factors for postoperative aggravation of CSA were assessed using multivariate logistic analysis.RESULTSOf the total number of patients studied, 67.0% (213 of 318) and 54.4% (173 of 318) showed cervical kyphotic alignment preoperatively and postoperatively, respectively. C2–7 lordosis increased (from −5.8° to −1.1°; p < 0.001) and C2–7 SVA decreased (from 24.2 to 20.0 mm; p < 0.001) postoperatively regardless of curve types. Although group K showed improvement in C2–7 lordosis (from −12.7° to −4.8°; p < 0.001), group L showed no difference (from 9.0° to 6.9°; p = 0.115) postoperatively. Clinical outcomes were not related to the degree of cervical kyphosis in this cohort. C2–7 lordosis (p < 0.001) and pelvic tilt (p = 0.019) were related to postoperative aggravation of CSA.CONCLUSIONSRegardless of the trend of improvement in CSA, many patients (54.4%) still showed cervical kyphotic alignment postoperatively. C2–7 lordosis and C2–7 SVA improved postoperatively in all curve types. However, postoperative changes in C2–7 lordosis showed different results based on preoperative CSA, which could be related to T-1 slope and thoracic kyphosis. However, clinical outcomes showed no difference based on CSA in this study cohort. Greater C2–7 lordosis and proximal thoracic curve preoperatively were risk factors for postoperative aggravation of CSA (p < 0.001 and p = 0.019, respectively).

The authors studied the radiological findings of compression on the posterior wall of the stomach due to nodal involvement by malignant lymphomas. Compression is nearly always seen when the pathological node are peripancreatic and around the splenic vessels and perigastric (near the lesser curvature on the posterior wall). The para-aortic lumbar nodes do not usually cause compression, because they He nearer the midline. They are usually shown by means of lower limb lymphangiography. The present study describes the most characteristic aspects of these lesions and it outlines the radiological findings in numerous cases of biopsy proven malignant lymphomas. The radiological diagnosis of nodal involvement was confirmed by the clinical evolution of the disease, by repeated X-ray examinations after chemotherapy and cobalt therapy and by exploratory laparotomies in the last two years. Because of the above data and their extensive experience in this field, the authors suggest that lateral gastric X-ray examinations could indicate in a high numer of involved cases the presence of lymphoma in this area. These data supply a new radiological parameter to help classify and plan the treatment of these systemic diseases more correctly.
