Structural vertebral changes in the horizontal plane in idiopathic scoliosis and the long-term corrective effect of spine instrumentation

Summary The rotation and structural changes of the apex vertebra in the horizontal plane as well as of the thoracic cage deformity were quantified by measurements on computed tomography (CT) scans from patients with right convex thoracic idiopathic scoliosis (IS). The CT scans were obtained from 12 patients with moderate scoliosis (mean Cobb angle 25.8°, r 13°–30°) and from 33 with severe scoliosis (mean Cobb angle 46.2°, r 35°–71°). In addition, CT scans of thoracic vertebrae from 15 patients without scoliosis were used as reference material. Ten of the scoliotic cases had had Cotrel-Dubousset instrumentation (CDI) and posterior fusion and had entered a longitudinal study on the effect of operative correction on the re-modelling of the apical vertebra. An increasingly asymmetrical vertebral body, transverse process angle, pedicle width and canal width were found in the groups with scoliosis as compared with the reference material. Vertebral rotation and rib hump index were significantly larger in patients with early and advanced scoliosis than in normal subjects. The modelling angle of the vertebral body, the transverse process angle index and the vertebral rotation in relation to the middle axis of the thoracic cage were significantly greater in patients with severe than with moderate scoliosis. The results of this longitudinal study suggest that the structural changes of the apical vertebra regress 2 years or more after CD instrumentation.     

The callous elbow and aging of the upper arm

The author describes his surgical approach to the problems of the aging upper arm and elbow region. Surgery at an appropriate age can prevent the progressive wrinkling of the elbow which is further aggravated by aging of the upper arm. The author's operation is aimed at correcting both portions of the arm anatomy at the same time.

内眦赘皮与重睑成形同期手术的一种新方法

目的 探索适合同时行重睑成形术和内眦赘皮矫正术的新方法。方法 根据内眦赘皮深部眼轮匝肌结构上的异常特点，遵循内眦赘皮的上睑（倒向性内眦赘皮除外）内侧睑缘处皮肤短缺和尽量减少局部皮肤瘢痕的原则，设计适合同时行重睑成形术的新内眦赘皮矫正术（反Stallard法）。结果 临床应用86例，进行了为期6个月以上的随访，结果所有患者的重睑为稳定性平行型重睑，内眦已完全或大部分开大，手术效果满意。结论 此内眦赘皮矫正术能够充分矫正内眦部结构上的异常，而且适合与重睑成形术同期施行，是一种效果稳定，结果满意的术式。     

多层螺旋CT尿路造影对上尿路梗阻性疾病的诊断价值

目的 探讨多层螺旋CT尿路造影（MSCTU）在上尿路梗阻性疾病诊断中的价值。资料与方法 搜集经静脉肾盂造影（IVU）或其他影像学检查提示上尿路梗阻而原因不明的患者58例，均行MSCTU检查，在图像工作站对获得图像进行最大密度投影（MIP）、多平面重建（MPR）及容积再现（vRT）等三维后处理，获得泌尿系立体图像。结果 58例中上尿路结石20例，先天性畸形14例，输尿管癌11例，输尿管炎性狭窄3例，输尿管息肉2例，副肾血管压迫肾盂输尿管交接处2例，邻近器官疾病导致上尿路梗阻2例，以上病例均经手术或输尿管镜检查证实。另有4例无法确诊，诊断准确率为93．10％。结论 MSCTU通过MPR、MIP、VRT技术多角度观察能够更加清晰地显示出导致上尿路梗阻的病变及其形态，在上尿路梗阻病变诊断方面有独特的优势。

Upper thoracic myelopathy caused by vertebral collapse and subluxation in rheumatoid arthritis: report of two cases

We report two cases of rheumatoid arthritis (RA) with upper thoracic myelopathy and a review of the literature. Clinical data of a 47-year-old woman (case 1) and a 54-year-old woman (case 2) are described. Case 1 showed a transverse-type myelopathy at the T2 segment level of the spinal cord and case 2 had the same type of myelopathy at the T4 segment level. Case 1 had anterior vertebral subluxation of C7 due to marked vertebral collapse and Case 2 had subluxation of T2 with vertebral destruction. These two patients had the mutilating type of RA with multilevel spontaneous fusion in the cervical spine. The lesions in the thoracic spine might be caused by the severe destructive inflammation that is characteristic in mutilating disease. The vertebral collapse might lead to subluxation of the upper thoracic vertebra, resulting in spinal cord compression. Upper thoracic subluxation might be caused by vertebral collapse due to RA and the increased motion as a compensation for decreased mobility caused by spontaneous fusion in the cervical spine.     

两种术式治疗甲状腺相关眼病上睑退缩的比较

目的对比两种术式矫正甲状腺相关眼病上睑退缩的临床疗效。方法将22例(32只眼)甲状腺相关眼病上睑退缩患者,随机分为A、B两组。A组11例18只眼采用上睑提肌中央腱膜切断术矫正;B组11例14只眼采用上睑提肌和Muller肌延长术矫正。术后随访6个月,评价其临床疗效。结果所有患者术后自觉症状均明显减轻或消失,A组及B组各自术前与术后疗效相比,均有统计学意义(P<0.01),组间比较无统计学意义(P>0.05)。术后6个月A组有4例6眼,B组有1例1眼上睑回退,经卡方检验,回退率组间比较有统计学意义(P<0.05)。两组均无一只眼过矫。结论两种术式均可有效矫正静止期甲状腺相关眼病的上睑退缩,但上睑提肌和Muller肌延长术回退率低。
