目的:探讨颈椎病与中医分型的辨证关系。方法:对100例该病的影像表现与中医分型进行系统分析。结果:主要临床表现颈部活动受限,颈、肩、背部疼痛,常伴头痛、头晕、视物模糊、耳鸣等症状。风寒型以软组织所致颈曲改变为主。肝肾亏虚型、痰湿交阻型以骨质增生、椎间隙及椎间孔狭窄为主。结论:X线、CT是本病首选检查方法,能与中医辨证有机结合,对中西医治疗有重要意义。     

Spinal canal narrowing during simulated frontal impact

Between 23 and 70% of occupants involved in frontal impacts sustain cervical spine injuries, many with neurological involvement. It has been hypothesized that cervical spinal cord compression and injury may explain the variable neurological profile described by frontal impact victims. The goals of the present study, using a biofidelic whole cervical spine model with muscle force replication, were to quantify canal pinch diameter (CPD) narrowing during frontal impact and to evaluate the potential for cord compression. The biofidelic model and a sled apparatus were used to simulate frontal impacts at 4, 6, 8, and 10 g horizontal accelerations of the T1 vertebra. The CPD was measured in the intact specimen in the neutral posture (neutral posture CPD), under static sagittal pure moments of 1.5 Nm (pre-impact CPD), during dynamic frontal impact (dynamic impact CPD), and again under static pure moments following each impact (post-impact CPD). Frontal impact caused significant (P<0.05) dynamic CPD narrowing at C0-dens, C2-C3, and C6-C7. The narrowest dynamic CPD was observed at C0-dens during the 10 g impact and was 25.9% narrower than the corresponding neutral posture CPD. Interpretation of the present results indicate that the neurological symptomatology reported by frontal impact victims is most likely not due to cervical spinal cord compression. Cord compression due to residual spinal instability is also not likely.     

歼击机飞行员颈椎X线分析

目的探讨我国歼击机飞行员受过载作用对颈椎及周围软组织的影响及其有效预防措施.方法对155名歼击机飞行员和127名地方人员颈椎异常发生率和各类颈椎X线表现进行对比分析.结果歼击机飞行员颈椎异常发生率与地方人员有非常显著差异,各类X线表现：椎体不稳、骨质增生、椎间隙变窄有非常显著差异,项韧带钙化、生理曲度异常有显著差异.结论持续性过载作用可致颈椎退变加剧.     

针刺推拿中药综合治疗颈性眩晕疗效观察

目的观察针刺推拿中药综合治疗颈性眩晕的疗效。方法设综合组80例、电针组42例、推拿组68例和中药组36例,进行疗效比较分析。结果综合组有效率为93.8%,电针组有效率为73.8%,推拿组有效率为86.8%,中药组有效率为69.4%,综合组有效率与其他几组比较差异均有统计学意义（P〈0.05）。结论采用电针、推拿、中药相结合的综合疗法治疗颈性眩晕集诸单一疗法之精华,避免单一疗法的局限性,可提高有效率。     

经皮穿刺颈椎髓核成形术治疗多间隙颈椎间盘突出症

目的:探讨经皮穿刺颈椎髓核成形术(percutaneous cervical nucleoplasty,PCN)治疗多间隙颈椎间盘突出症的临床疗效及其对颈椎稳定性的影响。方法:对我院2003年7月～2005年6月因颈椎间盘突出症住院行PCN治疗的64例患者进行回顾性研究,根据手术间隙分为两组:单间隙组(A组)34例,多间隙组(B组)30例。临床效果评价采用JOA评分标准(17分制并计算改善率),颈椎稳定性评价采用Katsumi标准。比较两组的临床效果及颈椎稳定性。结果:随访6～24个月,A组平均14.1±3.7个月,B组平均13.9±3.8个月,A组术前JOA评分为9.19±2.64分,术后为14.37±1.42分,改善率为66.3%;B组术前JOA评分为8.89±2.31分,术后为14.33±1.28分,改善率为67.1%,与术前比较均有显著性差异(P<0.001),两组患者的JOA评分改善率无显著性差异(P>0.05)。两组患者术后颈椎稳定性与术前比较均无显著性差异(P>0.05)。结论:PCN治疗多间隙颈椎间盘突出症效果优良,对颈椎稳定性影响小,不会造成颈椎失稳。     

Subakute Verlegung der Atemwege infolge eines retropharyngealen H?matoms nach Halstrauma

Mechanical airway obstruction secondary to retropharyngeal bleeding is rare. In most cases such a complication is described after head and neck trauma. Complicating factors include anticoagulant therapy, tumour, aneurysm, infection or major cervical spine injury. A precise initial diagnosis is necessary to avoid a life-threatening situation. Lateral X-ray and computed tomography is essential for safe management. Treatment depends upon size of the haematoma as well as the clinical course of the patient. Smaller haematomas may be observed. Lager haematomas and those that fail to reabsorb should undergo drainage.      

经后路钛网椎板成形侧块内固定术治疗脊髓型颈椎病的疗效观察

目的 观察后路钛网椎板成形侧块内固定加植骨术治疗脊髓型颈椎病的临床效果。方法 自1999年至今，共有16例脊髓型颈椎病患者经后路钛网椎板成形侧块内固定加植骨术治疗，对治疗结果进行临床及X线评定。结果 通过平均2年5个月的随访，所有病例都得到了改善，其中优6例、良8例、可2例，优良率为93．8％；术后椎管矢状径平均增加4．2mm，钛网无位置变化，并已被再生骨固定。结论 在进行后路减压的同时，钛网椎板成形及侧块内固定，尤其适用于有节段性不稳的脊髓型颈椎病并椎管狭窄、后纵韧带骨化症的治疗。     

中下段颈椎的应力松弛特性及前、后路手术对其的影响

目的 研究中下段颈椎的应力松弛特性，并评估椎间盘切除植骨术与椎板切开术对其影响。方法 6例新鲜尸体完整颈椎及手术后颈椎，在模拟生理状态下进行屈曲及伸展位的应力松弛实验。结果 在恒应变条件下，绘制术前及不同术式后的中下段颈椎的应力松弛函数及曲线；术后的中下段颈椎的应力和初始化应力比值G(t)比术前明显增大，前路椎间盘切除植骨术后的G(t)值比椎板切开术大，两者均有统计学意义。结论 在恒应变条件下，颈椎具有快速应力松弛敏感性，屈曲位比伸展位大。椎板成形术及颈椎前路椎间盘切除植骨术都使颈椎的应力松弛能力减弱，前路椎间盘切除植骨术的影响更大。
