目的:我们评估疗效,单阶段后释放的安全性和适应症,reduction,并固定基底内陷(BI)伴不可复性寰枢椎脱位(IAAD)。
方法:17例BI和IAAD患者连续接受一期释放,reduction,在2000年7月至2015年6月期间,患者接受了至少12个月的随访.有8个男性。平均年龄为5635.2±13.8岁(范围12-56)。记录患者的临床症状和体征。进行术前、术后影像学检查。使用日本骨科协会(JOA)和Ranawat评分评估神经功能。
结果:平均随访时间为47.4个月(12-97个月)。JOA评分由术前4-10分(8.06±2.52)增加至术后13-16分(15.20±0.62)。术前张伯伦线,麦克雷线,Wackenheim线,亚特兰大间隔,颈髓角为12.52±5.17毫米,6.59±3.04mm,6.96±4.32mm,9.88±1.93mm,115.35±12.40°,分别。术后数值为2.0±3.67mm,-3.06±1.85mm,-1.76±2.88mm,1.17±1.18mm,136.76±11.44°,分别。
结论:一阶段发布,reduction,并且通过后路固定BI和IAAD患者是安全有效的。
UNASSIGNED: We evaluate the efficacy, safety and indications of single stage posterior release, reduction, and fixation of basilar invagination (BI) with irreducible atlantoaxial dislocation (IAAD).
UNASSIGNED: Seventeen patients with BI and IAAD consecutively underwent one-stage release, reduction, and fixation by a posterior approach from July 2000 to June 2015 were followed up for at least 12 months. There were 8 males. Mean age was 56 35.2 ± 13.8 years (range 12-56). The clinical symptoms and signs of the patients were recorded. Pre- and postoperative imaging examinations were performed. Neurological function was assessed using the Japanese Orthopedic Association (JOA) and Ranawat scores.
UNASSIGNED: Average follow-up time was 47.4 months (12-97 months). The JOA score increased from preoperative 4-10 (8.06 ± 2.52) to postoperative 13-16 (15.20 ± 0.62). The preoperative Chamberlain line, McRae line, Wackenheim line, atlantodens interval, and cervico medullary angle were 12.52 ± 5.17 mm, 6.59 ± 3.04 mm, 6.96 ± 4.32 mm, 9.88 ± 1.93 mm, and 115.35 ± 12.40°, respectively. The postoperative values were 2.0 ± 3.67 mm, -3.06 ± 1.85 mm, -1.76 ± 2.88 mm, 1.17 ± 1.18 mm, and 136.76 ± 11.44°, respectively.
UNASSIGNED: One-stage release, reduction, and fixation for patients with BI and IAAD through a posterior approach is safe and efficient.
