Effects of the adjustive tractor in treatment of cervical dislocation

Objective To observe the clinical effects of the adjustive tractor for cervical dislocation.Methods Forty-seven patients were included between September 2007 and November 2011.There were 36 males and 11 females with age ranged from 7 to 62 (mean,35 years).The mean interval from injury to admission was 8.6 h (range,0.5-72 h).There were atlanto-occipital dislocation in 2 cases,C1.2 in 2 cases,C2.3 dislocation in 5 cases,C3.4 dislocation in 2,C4.5 in 9,C5.6 in 13,C6.7 in 14.Thirty cases were complicated by fracture.No facet locking occurred in sixteen cases.Facet locking was found in ten cases and bilateral facet locking was in 21 cases.After reduction,brace or internal fixation followed.According to American Spinal Injury Association (ASIA) spinal function impairment scale standard,there were 4 cases in level A,10 cases in level B,18 in C,10 in D,and 5 in E.According to Japanese Orthopaedic Association (JOA) spinal function rating standard,the mean JOA score was 9 (range,2-14).Results All 47 cases were reduced successfully without neuronal function aggravation.Traction power ranged from 7 to 60 kg (mean,25.6 kg),the mean time of traction was 8 min (range,3-10 min).The mean follow-up was 38 (range,6-48) months.All the patients achieved normal alignment and intervertebral height.The intervertebral body fusion was observed in all of cases,the mean fusion time was 3.3 months (range,3-6 months).One patient who experienced nonunion of vertebral arch fracture didn't receive further treatment because of absence of symptoms.At last follow-up,there were 3 cases in level A,1 in level B,4 in C,8 in D,and 31 in E according to ASIA scale.The mean JOA score was 12 (range,2-17).Conclusion The adjustive tractor is simple and safe for prompt reduction.

Effects of bedside rapid skull traction in treatment of cervical dislocations with locked facet

目的 探讨床旁快速牵引复位在治疗颈椎关节突脱位交锁中的作用,以期找到快速牵引的适用情况.方法 回顾性分析1992年6月～2004年3月颈椎外伤致关节突脱位交锁术前行颅骨牵引快速复位的33例患者的临床资料.双侧关节突脱位交锁21例,单侧关节突交锁12例.常见脱位节段:C4.58例、C5,6 15例和C6,7 10例.所有患者均采用床旁颅骨牵引快速复位法,牵引复位成功者均采用颈椎前路间盘切除植骨融合;复位失败者行颈后路切开复位内固定术.结果 双侧颈椎关节突脱位交锁者牵引复位成功率为85.7%,单侧颈椎关节突脱位交锁患者牵引复位成功率为16.6%,两组间差异有统计学意义(P＜0.01).23例患者获平均21.6个月(13～36个月)随访.随访病例中植骨融合者均获骨性愈合,颈椎序列良好.结论 床旁颅骨快速牵引复位法适用于双侧颈椎关节突脱位交锁患者;双侧关节突脱位交锁患者可先行颅骨快速牵引复位,复位后行颈前路间盘切除植骨融合术;单侧颈椎关节突脱位交锁患者宜行后路切开复位。

Treatment of cervical dislocation with locked facets

Lower cervical dislocation with locked facets is common in cervical injury. The locked facets include unilateral and bilateral types. Different successful closed reduction rates has been achieved between unilateral and bilateral types by using rapid skull traction, which was commonly used to reduce the cervical dislocation. It is important to investigate a suitable management specific to patients with different types of cervical locked facets. A total of 38 patients with cervical dislocation with locked facet due to cervical injury treated by rapid skull traction and operation from 1988 to 2005 were reviewed. Rapid skull traction was used in all the patients. Successful closed reduction rate was 88.0% in patients with bilateral cervical locked facets and that was 15.4% in those with unilateral cervical locked facets. These data were then statistically compared by Chi-square test. Patients who were reduced successfully underwent anterior cervical discectomy and fusion at the injured level, and those who failed in closed reduction received posterior open reduction and fixation. In this series, there was statistically significant difference (P < 0.05) in the rate of successful closed skull traction reduction between unilateral and bilateral locked facets dislocation. Unilateral cervical locked facets dislocation was not easily reduced by skull traction which was suitable for reduction of bilateral cervical locked facets dislocation. However, unilateral cervical locked facets dislocation can be reduced by posterior open reduction. Unilateral cervical locked facets dislocation should be treated immediately with posterior open reduction and instrumentation. Bilateral cervical locked facets dislocation can be reduced by rapid skull traction firstly and anterior cervical discectomy and interbody fusion later.

REDUCTION OF CERVICAL DISLOCATIONS

1. The trends in treatment of cervical dislocation are reviewed. 2. Seventeen patients treated by manual reduction under general anaesthesia are reported. 3. The evidence is that reduction in this way is not dangerous and has advantages over other methods.
