Results MPR and SSD techniques can acquire lots of important information:(1)rule out the diagnosis of fracture and dislocation and its type can be patient has been injured so badly that cannot take X-ray examination.(2)detect the secret fracture and missing fracture in X-ray examination because of overlap.(3)diagnose the missing transverse fracture in routine CT scan.(4)diagnose the atlantoaxial joint luxation without fracture.
结果 MSCT扫描MPR、SSD技术在寰枢椎外伤中可:(1)对于外伤后病情不适合拍平片者,MSCT能快速、准确地明确骨折、脱位的有无及其类型;(2)MSCT轴位扫描结合MPR能排除因平片结构重叠漏诊的骨折以及平片不易发现的隐匿骨折;(3)MPR对椎体发生的常规轴位扫描易漏诊的水平型骨折线能明确诊断;(4)对于没有骨折的寰枢关节半脱位能提供可靠的依据。

Results In 7 cases of odontoid process fracture, X-ray demonstrated 4 cases and CT demonstrated 5 cases, whereas the spiral CT reconstruction diagnosed 7 cases, which could display the displacement of fracture clearly. The X-ray and CT showed asymmetric space between left and right gaps of atlantoaxial joint in 6 cases, while spiral CT reconstruction showed normal and excluded the possibility of atlantoaxial dislocation. There was one case of lateral atlantoaxial joint dislocation, which was demonstrated by the spiral CT reconstruction clearly but not by the X-ray and CT scan. There were 3 cases of atlantoaxial congenital deformity (1 case of absence of both posterior arch of atlas and odontoid process and 2 cases of maldevelopment of the odontoid process), which were displayed clearly by spiral CT reconstruction, but misdiagnosed as odontoid process fracture and atlantoaxial subluxation by X-ray and CT scan.
结果 7例齿状突骨折中,X线显示4例,CT显示5例,CT重建确诊7例,且清楚显示骨折移位情况;6例X线、CT显示寰枢椎左右间隙不对称,通过CT重建排除寰枢关节半脱位;寰枢外侧关节脱位1例,CT重建可清楚显示,而X线片和CT平扫均未能显示;寰枢椎畸形3例,分别为齿状突、后弓缺如1例,齿状突发育不良2例,CT重建均能清楚显示,而X线、CT均误诊为齿状突骨折、寰枢椎半脱位。

The peak of the bulge accorded with the vertical line through the posterior convexity of superior articular surface of atlas. The superimpose rate of the vertical line with the M line were 48% to left and 65% to right. The surplus existed in l~2mm to lateral of M line. The exit point of screw was the median point of vertical line on the anterior cortex of lateral mass. The superimpose rate of BB line the line linked with the

Methods: Injured patients of cervical spine was cayyied on X-ray inspection.,then according to the result of ADI and LADS ,next to CT or MRI inspection ,and that was to guide clinical diagonosis and treatment.To observe atlanto-dental interval (anterior arch of atlas posterior border to odontoid process anterior border) and odontoid process caster(included angle between axis of ordinate of odontoid process and axis of ordinate of odontoid vertebra) on the X-ray lateral projection.
对有颈部外伤史的病人常规行X线检查,然后根据寰齿间距和齿突侧块间隙的结果,行下一步CT检查或者MRI检查,指导临床治疗方法的选择。X线侧位片观察寰齿前间隙(为寰椎前弓后缘与齿突前缘距离),齿状突后倾角(齿突纵轴与枢椎体纵轴的夹角);开口正位片上测定齿突侧块间隙。

[Objective] To analyze the outcome of internal fixation for occipitalization with atlantoaxial joint dislocation by posterior decompression and occipitocervical fusion [Method] From December 2005 to June 2007,8 patients with occipitalization and atlantoaxial joint dislocation received removal of the posterior arcus of atlas and the enlargement of the posterior edge of the foramen magnum after skull traction performing for an average of 135 daysAll patients were operated on by posterior craniocervical fusion using cervifix internal fixation system and autologous ilium graftsThe clinical efficacy after operation was analyzed by Japanese Orthopaedic Associationneural function score [Result] All the patients were followed up from 6 months to 2 years, average of 15 monthsNo complication was foundAtlantodental interval was 5~9 mm before and 4~6 mm after skull tractionAtlantoaxial joint dislocation didn't completely reducedThe neurological defects were improved to some extents according to the JOA scoreImageology showed all patients had full decompression and bony fusionThe loosening or broken internal fixation was not found [Conclusion] Posterior decompression and fusion is a feasible method for the treatment of occipitalization with atlantoaxial joint dislocation,and the clinical effect is satisfactory
分析后路减压枕颈融合内固定术治疗合并寰枢关节脱位的寰椎枕骨化临床疗效。[方法]2005年12月至2007年6月间,对8例合并寰枢关节脱位的寰椎枕骨化患者在行颅骨牵引治疗一段时间(12~16 d,平均135 d)后采用枕骨大孔后缘扩大,寰椎后弓切除减压取自体髂骨枕颈融合Cervifix系统内固定术,手术后采用日本骨科学会神经功能评分分析临床疗效。[结果]8例患者随访6个月~2年,平均为15个月。8例患者无一例出现术后并发症,术前寰齿前间隙为5~9 mm,经颅骨牵引后为5~7 mm,寰枢关节脱位未能完全复位。手术前后JOA评分示神经症状均有不同程度恢复,影像学检查示枕颈区减压充分植骨区获得骨性融合,无一例出现内固定松动或断裂。[结论]合并寰枢关节脱位的寰椎枕骨化患者术前仔细评估影像学改变,采用颅骨牵引一段时间后行后路减压枕颈融合内固定术的治疗方案是合理可行的,且临床效果满意。
