颈椎骨折类型与脊髓损伤关系之临床观察

通过对９２例颈椎骨折病例的分析，发现屈曲型损伤最多见（５３％），其次为过伸型（２６％），压缩型（２１％）。屈曲型和压缩型多见于年轻人，而屈曲损伤导致的脱位及过伸型则多见于年龄较大者。爆裂骨折引起的神经损害最重，其次为屈曲型、过伸型及压缩（非爆裂）骨折。神经功能改善率以爆裂型骨折最差，死亡率亦最高，以压缩（非爆裂型）骨折最好，其次为过伸型及屈曲型。文内对各型的特点进行了详细讨论。     

Long-term follow-up by video of cervical dystonia treated with botulinum toxin

We have analysed video recordings of 21 patients with cervical dystonia treated with botulinum toxin. Fourteen patients have a record both of their response shortly after injections were commenced and between four years five months and six years seven months later. Our analysis shows that the long term outcome is often better than the initial response. We suggest that chronic treatment with botulinum toxin allows different muscles to those initially injected to be identified as contributors to the dystonia. Subsequent injection of these muscles leads to further improvement. It implies that cervical dystonia is a more widespread disorder of motor control, rather than simply limited to a few muscles.     

Case-control study of risk factors for cervical neoplasia in Denmark. II. Role of sexual activity,reproductive factors,and venereal infections

Sexual, reproductive and venereal risk factors for cervical neoplasia were investigated in a population-based case-control study of 586 women with histologically verified, cervical squamous-cell carcinoma in situ, and 59 women with invasive squamous-cell cervical cancer, diagnosed from 1985 to 1986 in Copenhagen. Cases were identified from the computerized Danish Cancer Registry. An age-stratified control group (n=614) was drawn at random from the female population in the study area by means of the Danish Central Population Register. A structured questionnaire was mailed to cases as well as controls. Increasing number of sexual partners exerted a significant effect on the risk both for carcinoma in situ, and invasive cancer, independently of age at first intercourse and other potential confounders. Conversely, the association with early age at first intercourse became statistically insignificant after allowance for other risk factors, although an increasing risk was still observed with decreasing age at sexual debut. Early age at first episode with genital warts was a significant risk factor for carcinoma in situ, perhaps indicating a possible increased susceptibility of the cervix epithelium during adolescence. A history of genital warts was a good predictor of risk for carcinoma in situ, whereas a history of previous gonorrhea was associated with an increased risk for invasive carcinoma. Women with multiple births had a significantly increased adjusted risk, especially for carcinoma in situ, although some association was also observed with invasive cervical cancer. The study supports the hypothesis of cervical neoplasia being a sexually transmitted disease, and that carcinoma in situ and invasive cervical carcinoma, to a high degree, have similar patterns of risk factors.Drs Kjaer, Engholm, and Lynge are with the Danish Cancer Registry.

对AF系统整复压缩爆裂骨折椎体高度及椎管横截面的观测

目的 :量化评价AF系统恢复胸腰段压缩爆裂椎体高度椎管截面积的效果。方法 :测量AF系统治疗的 72例胸腰段压缩爆裂骨折术前后影像。统计椎体前后缘高度、Cobb角、椎管截面积资料。结果 :术后伤椎前缘高度恢复至 ( 96.5± 2 .3 ) %后缘高度恢复至 ( 98.2± 0 .9) % ,Cobb角恢复至 ( 5 .4± 1.5 )° ,椎管截面积恢复至 ( 97.2± 2 .1% ) ,各项指标与术前比较有非常显著性差异 (P <0 .0 0 1)。术后随访 0 .5～ 3 .5年 ,神经功能按Frankel评定 :60例提高 1～ 3级。结论 :AF系统能恢复或基本恢复胸腰段压缩爆裂骨折椎体的前后缘高度、Cobb角、椎管容积 ,为脊髓神经功能的恢复提供一个良好的环境。是治疗脊柱胸腰段压缩爆裂骨折较好的内固定器。     

腰椎管狭窄症的手术减压与内固定选择(259例临床分析)

目的：探讨腰椎管狭窄症的手术减压指征、减压范围及内固定选择。方法：回顾性分析腰椎管狭窄症患者259例，平均年龄52．2岁，平均病程4年1个月。根据病情分别采用椎板间节段开窗潜行减压术139例，腰椎管内径扩大成形术63例，全椎板切除减压、椎间植骨融合内固定术57例。结果：221例获得平均4年2个月随访。三种手术方法优良率分别为91．53％、87．50％和85．45％；手术并发症发生率为13．69％、15．87％和20．11％。结论：对严重的腰椎管狭窄症若手术适应证和减压范围掌握恰当，不论采取何种手术方式的神经减压术，均可取得满意疗效。正确选择病例和熟练的外科技术是应用内固定器械的重要条件。     

前路减压Z-plate内固定治疗胸腰段爆裂性骨折伴不全性截瘫

颈椎前路钢板椎间融合器系统治疗颈椎间盘突出症

颈椎前路手术在颈椎间盘疾病中已广泛应用，手术方法主要为颈前路减压加椎间植骨融合术。但不管是早期的自体骨融合的颈前路手术，还是后来进一步发展的颈前路钢板以及椎间融合器技术，都存在着诸如融合失败率高、植骨块移位、塌陷、螺钉断裂、钢板松动等并发症，造成手术疗效不佳以致于二次手术。自2002年2月-2004年1月采用颈椎间盘摘除、颈椎前路钢板椎间融合器（PCB）系统内固定、植骨融合术治疗颈椎间盘突出症后均无前述并发症的发生，疗效满意，现报道如下。
