腰椎间盘突出合并椎管狭窄的手术治疗

报告手术治疗腰椎间盘突出症合并退行性腰椎管狭窄症１０４例。术后随访９０例，随诊时６个月～６年。优良率８６．５％，无腰椎不稳和腰椎滑脱等并发症。为获得优良效果，作者强调在处理椎间盘突出的同时必须彻底解除侧隐窝及神经根管，黄韧带肥厚对神经根的压迫，才能彻底根除症状     

胶原酶溶解术治疗腰椎间盘突出症

采用国产胶原酶行腰椎间盘内注射治疗腰椎间盘突出症９０例。有效率为９３％，优良率为８４％。作者体会该方法创伤小，无出血，对椎管内无干扰。只要严格选择适应症，掌握正确的操作方法，无疑是一种有效的治疗方法。

开放手术观察腰椎间盘突出症溶核失败45例分析

目的 通过开放手术观察分析椎间盘髓核化学溶解术治疗腰椎间盘突出症失败原因。方法 收集溶核失败的腰椎间盘突出症45例行开放手术治疗。结果 术中见45例硬膜外脂肪完全消失，43例髓核未见溶解，2例髓核溶解呈糊状但未被吸收，21例伴有侧隐窝狭窄，15例突出物与神经根粘连，20例黄韧带增厚，2例椎管骨性狭窄，14例突出物钙化。结论 腰椎间盘突出症病变间隙合并有侧隐窝狭窄、神经根粘连、椎管狭窄、突出物钙化等，不是溶核治疗的适应证。     

Gd-DTPA-enhanced MR in thoracic disc herniations

Summary The Gd-DTPA-enhanced magnetic resonance findings in two patients with herniated thoracic intervertebral discs are reported. The first patient was a 56-year-old woman with a small subligamentous T6-7 disc herniation, slightly lateralized to the right. The second patient was a 51-year-old man with a central and right posterolateral disc herniation, including a large calcified fragment, at the T8-9 level. The nonenhanced MR examination revealed the presence of an extradural mass lesion in both patients, impinging upon the dural sac and compressing and displacing the spinal cord posteriorly. The lesion was slightly hypointense on both T1- and T2-weighted spin echo sequences. Following intravenous injection of Gd-DTPA in a dosage of 0.1 mmol/kg body weight, enhancement of the posterior longitudinal ligament was noted and triangular areas of contrast uptake were seen to occur in the epidural space above and below the herniated disc. At surgery, they were found to correspond to dilated and congested epidural veins.     

超声引导胶原酶治疗外侧型腰椎间盘突出症

目的探讨超声引导胶原酶治疗外侧型腰椎间盘突出症的疗效及安全性.方法在相应椎间盘突出的棘突间,旁开1.5～2.5cm处经皮穿刺,采用超声引导定位,穿刺成功后,先进行加压试验,再进行麻醉试验,无腰麻征象后,将胶原酶注入到突出的椎间盘内或周围.结果 231例病人出院时的优良率为92.21%,有效率为99.57%;随访1～5年的优良率为92.65%,有效率为99.58%.近期与远期疗效比较无显著性差异(χ2=0.129,P＞0.05).结论利用超声引导监测、定位,注射胶原酶治疗外侧型腰椎间盘突出症,安全性强、有效率高.     

小切口椎板间开窗治疗腰椎间盘突出症

目的　探讨小切口椎板间开窗髓核摘除术的疗效及适应证。方法　从 1998年 5月～ 2 0 0 1年 9月采用小切口椎板间开窗髓核摘除术治疗腰椎间盘突出症 72例。全部患者都有腰痛和一侧或双侧下肢疼痛及麻木。结果　获得随访 65例 ,随访时间最长 2 6个月 ,最短 6个月 ,平均 13个月 ,按Nakai标准评定治疗优良率为 93 .8%。结论　小切口椎盘间开窗髓核摘除术具有适应证较广、手术时间短、出血少、创伤小、手术优良率高、后期并发症少、不损害脊柱稳定性等优点 ,是治疗腰椎间盘突出症较为有效和可靠方法之一     

腰椎间盘突出症和马尾神经综合征

本文报告３２例腰椎间盘突出症导致的马尾神经综合征。除腰痛及坐骨神经痛外，本组所有病人均存在鞍区麻木和括约肌功能障碍。根据尿便功能障碍发作程度和持续时间，本组有四种不同的临床表现类型，预后差。异较大。脊髓造影具有诊断和鉴别诊断价值，应用Ｏｍｎｉｐａａｕｅ较Ｃｏｎｒａｙ安全。早期诊断和手术治疗，对括约肌功能、肌力和鞍区浅感觉最大程度地恢复甚为重要。     

VASCULAR COMPLICATIONS OF ELECTIVE LOWER LUMBAR DISC SURGERY

Lower lumbar disc surgery is an extremely common operation from which vascular complications are reported rarely. However vascular injury can occur with perforation of the anterior longitudinal ligament. External haemorrhage is uncommon and the true cause of the patient's hypotension may be misdiagnosed. If the hypotension is severe or prolonged laparotomy is indicated, to prevent exsanguination and to effect a repair of the vascular injury. Alternatively, if the injury is missed, an arteriovenous fistula may develop; this diagnosis may be delayed for months or years. One case of severe haemorrhage following lower lumbar disc surgery is reported and a further 69 cases of similar arterial injury have been reviewed from the world literature.     

PARS INTERARTICULARIS STRESS AND DISC DEGENERATION IN CRICKET'S POTENT STRIKE FORCE: THE FAST BOWLER

Cricket fast bowlers are the potent strike force in a multidiscipline team. They subject their spines to repetitive sagittal plane and rotatory movements over many years. The effect of this repetitive stress has not previously been analysed. This study examined 20 former fast bowlers to determine the incidence of spondylolysis, spondylolisthesis and degenerative change. Fast bowlers are noted to have an increased incidence of spondylolysis. A mixed front/side bowling style involving more lumbar hyperextension or rotation has significant association with spondylolysis when compared with side-on bowling styles. There was a high incidence of radiological thoracolumbar degenerative facet joint and disc disease in former fast bowlers.
