Fracture separation of the articular pillar of C5 following brass knuckles trauma

We report the case of a fracture separation of the articular pillar at the lower cervical spine. The trauma, following a brass knuckles, repeats almost in an experimental way the rotation and extension mechanism given in literature for the genesis of such injuries. From the admission in the orthopaedic service to the surgery, the development went in a characteristic way towards a rotatory displacement.

颈椎椎体次全切除钛网钉板系统的临床应用

目的探讨颈椎前路椎体次全切除钛网钉板植骨融合的临床效果。方法自2001年3月～2003年3月间应用颈前路椎体次全切除钛网植骨融合及钉板固定治疗颈椎管狭窄性疾病22例，其中4例患者行2椎体次全切除3节椎间隙减压手术。术后观察减压、固定、融合及神经功能恢复情况，并行X线摄片或CT扫描检查。结果患者获6～12个月随访，神经功能得到不同程度改善，无加重情况。椎间隙高度无丢失、无成角，均获得骨性融合。术后3d在颈围领固定下下床活动，4周后可恢复较轻工作。结论此术式可避免传统手术方法的缺点，即不取自体髂骨，融合率高，稳定性好，并减压彻底，疗效好，是一种值得推广的新技术。     

The trajectory of the sympathetic nerve fibers to the rat cochlea as revealed by anterograde and retrograde WGA-HRP tracing

Wheat germ agglutinin-horseradish peroxidase conjugate was injected in the unilateral superior cervical ganglion (SCG), and the projection pathways of postganglionic sympathetic nerve fibers innervating the cochlea were traced in the rat. The labeled axons advanced along the internal carotid artery (ICA), and a few advanced caudally in the major petrosal nerve (MPN) and entered the facial nerve, while the majority ran rostral to the pterygopalatine ganglion at the point where they crossed the MPN in the carotid canal. The rest of the labeled fibers remained on the surface of the ICA and advanced to the cranial cavity. Most of the labeled fibers along the facial nerve joined the cochlear nerve and finally reached the osseous spiral lamina through the spiral ganglion. Some of the labeled fibers ran along the anterior inferior cerebellar artery from the basilar artery which was previously thought to have been the only pathway. We could not find any labeled fiber on the modiolar artery from anterior inferior cerebellar artery in the cochlea. These observations are consistent with our hypothesis that the sympathetic fibers innervating the neural tissues or related structures follow nerve fibers and meninges as matrices of projection pathways rather than arteries.     

用尿谷胱甘肽过氧化物酶评定颈椎病的康复疗效

测定了44例颈椎病患者康复前后尿液中谷胱甘肤过氧化物酶(GSH-Px)活力的变化。患者在治疗前,尿中GSH-Px活力为1080±310U/L((?)±s),与健康对照组相比差异有高度显著性(P<0.001)。推拿和颈牵治疗后尿中GSH—Px活力平均下降38.8%,且下降幅度和疗效之间有着明显的平行关系。据此,我们认为颈椎病的发病可能和体内自由基代谢紊乱有关,同时认为,无创伤的尿GSH—Px活力测定可以作为颈椎病康复疗效评定的客观指标,从而为颈椎病康复疗效的评定提供科学的生化依据。     

亲水性聚氨酯宫颈扩张棒在引产中的应用

初产妇30例,用亲水性聚氯酯泡沫宫颈扩张棒(简称“扩张棒”)作人工剥膜与破膜加催产素引产前扩张宫颈,同时以条件类同初产妇30例进行对照。扩张棒组置棒前宫颈成熟度评分为2.93±0.91,对照组为3.7±0.88,两组无显著差异:扩张后宫颈评分为6.13±1.22,与扩张前有显著差异(P<0.05)。扩张棒组引产成功率为92.6%,而对照组为64.3%,差异非常显著(P<0.01),同时能缩短产程。本组用扩张棒组引产的30例,无一例发生产时、产后感染。     

肩肱皮瓣修复颈部瘢痕挛缩畸形疗效分析

目的:探讨颈部瘢痕挛缩畸形的有效外科治疗手段。方法:采用瘢痕广泛松解、双侧或单侧肩肱皮瓣转移,同时用全厚皮片移植修复供瓣区创面。结果:本组21例中,17例手术一次性完成,4例分两次完成。不但改善了患者的上肢功能,还可进一步改善患者颈部的活动度。结论:瘢痕广泛松解、双侧或单侧肩肱皮瓣转移,同时用全厚皮片移植修复供瓣区创面是颈部瘢痕挛缩畸形的有效外科治疗手段。     

颈前路带锁钛板在脊髓型颈椎病手术中的应用

目的评价脊髓型颈椎病前路减压后应用带锁钛板内固定的价值。方法对51例脊髓型颈椎病患者采用前路减压、取自体髂骨植骨和颈椎带锁钛板内固定治疗。结果随访43例,平均随访时间2a,术后3个月植骨块获得骨性融合,颈椎椎间高度和生理曲度维持满意,感觉、肌力明显恢复,钛板及螺钉无松动及断裂现象。结论脊髓型颈椎病前路减压术后应用带锁钛板内固定能促使植骨块融合,有效地维持椎间高度和颈椎生理曲度,有较高的应用价值。     

Asynchronous blepharospasm, facial and cervical dystonia, and bilateral asynchronous hemifacial spasm.

We present a patient with a facial movement disorder that has characteristics of both blepharospasm and bilateral asynchronous hemifacial spasm. Because of the increased incidence of blepharospasm in patients with hemifacial spasm, our patient's clinical presentation is probably not a chance occurrence, but rather a manifestation of some predisposition for these two movement disorders. This unusual constellation of signs and symptoms challenges the current diagnostic criteria and suggests that some of these facial movement disorders may lie on a spectrum, rather than represent distinct entities.     

头环牵引外固定架治疗颈椎外伤的临床研究

[目的]探讨头环牵引外固定架治疗颈椎外伤的临床疗效。[方法]从1997年2月~2005年7月共收治129例颈椎外伤性骨折脱位患者。将129例病例随机分成2组,1组70例行头环牵引,其中31例头环牵引加背心带支架保守治疗,39例头环牵引加手术治疗(前路手术18例,后路手术17例,前后路联合手术4例);另1组59例行颅骨牵引,其中13例颅骨牵引加支具保守治疗,46例颅骨牵引加手术治疗(前路手术22例,后路手术20例,前后路联合手术4例)。[结果]随访6~48个月,平均12个月。头环牵引与颅骨牵引对上颈椎骨折脱位的复位作用无明显差异;对下颈椎骨折脱位的复位作用,统计学处理显示头环牵引组要明显好于颅骨牵引组,复位所需时间比颅骨牵引组短,完全复位率高,减压充分,更有利于脊髓功能恢复,治疗后离床时间头环牵引组要短于颅骨牵引组,2组患者治疗前后脊髓功能Frankel分级均有改善。[结论]头环牵引外固定架可改善复位功能,对颈椎的牵引固定作用较颅骨牵引更为坚强稳定,使用安全方便。
