颈椎后纵韧带骨化的治疗方法

从１９８３年８月至１９９１年３月，手术治疗６３例颈韧后纵韧带骨化（ＯＰＬＬ）的患者。手术方法包括前路椎间减压融合，椎体次全切除植骨融合、后路全椎板切除。单开门椎板成形椎管扩大手术、双开门椎板成形椎管扩大手术，及前后路两次手术。随诊６到９６个月，疗效为３９例代。１６例良，优良率８７．２％。本文讨论了前路椎间减压、椎体次全切除及后路椎板成形椎管扩大手术的方法。作者认为对ＯＰＬＬ伴广泛性椎管狭窄者以后路双开门椎板成形椎管扩大手术较为合理。     

重型颅脑损伤持续颅内压及脑灌注压监护与预后关系

作者对５０例重型颅脑损伤患者（ＧＣＳ３－８分），及５０例伤情与诊断和手术方式基本相似的另一组患者进行颅内压（ＩＣＰ）与脑灌注压（ＣＣＰ）连续监测对比研究。结果表明，监护组除８例ＩＣＰ压力＜２．００ｋＰａ，ＣＰＰ＞９．３３ｋＰａ外，余４２例均有不同程度ＩＣＰ增高与ＣＰＰ降低。这些患者分别为创伤性颅内血肿、广泛性脑挫裂伤、继发性脑水肿或脑肿胀等，均采取积极的手术及综合治疗。死亡率为１４％。非监护组治疗方法与监护组相同，预后较差且并发症多，死亡率为２８％。作者认为，对重型颅脑损伤患者施行连续ＩＣＰ、ＣＰＰ监护，是降低并发症和死亡率，提高疗效的有力措施，具有重要的临床应用价值。     

Mandibular fracture not shown by axial computed tomography: Benefit of computed reformation

A 36-year-old man was brought to the emergency department after being assaulted. A mandible series showed a nondisplaced fracture through the angle of the mandible extending through the left third molar tooth. Axial slices from a nonhelical computed tomographic (CT) examination of the head as well as a helical CT examination of the mandible failed to demonstrate the fracture. The fracture was well shown, however, on sagittal CT reformations. Although CT is generally regarded as more sensitive than plain radiography for the detection of fractures, fractures may be overlooked by CT if examination in only one plane is performed.     

手部创伤性骨关节缺损的处理

治疗手部骨关节缺损常采用植骨内固定、关节融合、关节成形及关节置换等方法．为总结经验，对１９８９年以来１０１例手部创伤性骨与关节缺损进行分析。单纯掌、指骨缺损３９例，行直接短缩对位，克氏针内固定６例，１例发主骨不连；对３３例缺损较大者用自体骨块植入克氏针交叉内固定，部分病例同时植人ＲＢＸ或异体骨粒，１０例发生延迟愈合，余全部正常愈合。骨与关节部分或完全缺损６２例，采用关节成形术４６例，其中以肋软骨移植效果最好，骨膜移植次之，筋膜衬垫或硅胶膜植入法较差；行关节融合术１１例．均达顺利融合；采用自体关节置换５例，均成活，术后关节活动度均＞７０°。我们认为：自体骨块植入克氏针交叉内固定，必要时植入ＲＢＸ骨粒．是治疗手部创伤性骨缺损的有效方法。关节缺损应按关节的重要性，分别采用关节融合术、关节成形术或关节置换术。     

Arthroscopic all-inside repair techniques of lateral meniscus anterior horn tear: a technical note

Although the conventional outside-in technique is especially useful for repairing tears in the anterior portion of the meniscus, it has a disadvantage of making an additional 1–2 cm sized skin incision and tying knots subcutaneously over the capsule. Therefore we devised two all-inside repair techniques of lateral meniscus anterior horn tear according to the site of meniscal tear, meniscosynovial junction or red–red zone. Because these techniques are modified methods of the outside-in meniscal repair using a spinal needle, they are as simple as conventional outside-in technique. In addition they have advantages of vertical mattress suture, which is an important characteristic of the all-inside repair, and no additional incision. We recommend these techniques as an alternative method for repairing an anterior horn tear of the lateral meniscus.     

Recurrent locking of knee joint caused by intraarticular migration of bioabsorbable tibial interference screw after arthroscopic ACL reconstruction

Two cases are reported in which, after ACL reconstruction with autologous hamstring grafts, tibial polylactide interference screws migrated into the knee joint. Clinically, both patients presented with recurrent locking of the joint. In one case, a broken 15 mm-long tip of the screw was found intra-articularly. In the other case, the whole screw had migrated into the joint cavity. The degradation process of polylactic acid, operative technique and bone quality are discussed as possible reasons for these complications.     

超声检查在男性创伤性尿道狭窄诊断中的价值

目的探讨超声检查对男性创伤性尿道狭窄的诊断价值。方法对21例男性创伤性尿道狭窄患者进行超声检查,14例同时联合尿道造影检查,结果与术中所见进行对比分析。结果21例超声结果与术中所见一致。14例联合检查中,造影检查有2例前尿道狭窄漏诊,2例狭窄近侧结石未发现,2例正常后尿道误诊为狭窄,2例后尿道狭窄长度不能估计;2例会阴部瘘管造影清晰显示而超声显示不佳。结论超声在狭窄定位、长度测量、瘢痕范围估测及显示继发结石等方面优于造影,造影显示瘘管清晰,必要时两者应联合应用。     

多发伤患者外周血降钙素原及C反应蛋白的动态变化及意义

目的探讨多发伤患者外周血降钙素原(procalcitonin,PCT)与C反应蛋白(C reac- tive protein,CRP)的动态变化及其临床意义。方法将96例多发伤患者按照ISS、输血量的多少、有无MODS、感染、脓毒血症及预后情况进行分类,分别检测不同类别患者外周血PCT、CRP浓度。结果与对照组相比,多发伤患者PCT和CRP均明显升高,其峰值分别出现在伤后2 d (PCT),5,7 d(CRP)。发生MODS、感染及脓毒血症时,PCT和CRP均明显升高。此外,PCT还与患者ISS评分、预后和输血量具有相关性。结论联合检测PCT、CRP有助于多发伤患者伤情的诊治及预后判断,其中PCT较CRP更具有敏感性。     

关节镜下采用四股和八股腘绳肌肌腱双束重建前十字韧带的比较研究

目的比较关节镜下采用四股和八股腘绳肌肌腱双束重建前十字韧带的临床效果。方法2001年9月至2002年8月,将76例陈旧性前十字韧带损伤患者随机分为两组进行双束重建。一组采用四股腘绳肌肌腱移植物:取同侧半腱肌肌腱,做成两个两股肌腱移植物,分别重建前十字韧带前、后束;一组采用八股腘绳肌肌腱移植物:取同侧半腱肌肌腱做成一个四股肌腱移植物重建前束,取同侧股薄肌肌腱做成另一个四股肌腱移植物重建后束。按照IKDC、Lysholm和Tegner膝关节评分标准评价疗效。结果四股肌腱移植物组有33例、八股肌腱移植物组有35例获得随访,随访时间1～3年,平均16个月。四股肌腱移植物组KT-1000检查示,双侧膝关节前向松弛度差异<3mm者25例(75.8%,25/33),3～5mm者5例(15.2%,5/33),6～10mm者3例(9.1%,3/33);轴移试验阴性28例(84.8%),阳性5例(15.2%)。八股肌腱移植物组KT-1000检查示,双侧膝关节前向松弛度差异<3mm者33例(94.3%,33/35),3～5mm者2例(5.7%,2/35);轴移试验阴性34例(97.1%),阳性1例(2.9%)。根据IKDC检查标准,四股肌腱移植物组有29例(87.9%,29/33)、八股肌腱移植物组有34例(97.1%,34/35)为正常或者接近正常,Lysholm评分分别为(90.2±2.9)分和(97.3±1.7)分,两组比较差异有统计学意义(P<0.05)。结论关节镜下采用八股腘绳肌肌腱较采用四股腘绳肌肌腱双束重建前十字韧带能够明显提高膝关节稳定性。
