Nonoperatively treated burst fractures of the thoracic and lumbar spine in adults: a 23- to 41-year follow-up

BACKGROUND CONTEXT: Several studies report a favorable short-term outcome after nonoperatively treated two-column thoracic or lumbar burst fractures in patients without neurological deficits. Few reports have described the long-term clinical and radiological outcome after these fractures, and none have, to our knowledge, specifically evaluated the long-term outcome of the discs adjacent to the fractured vertebra, often damaged at injury and possibly at an increased risk of height reduction and degeneration with subsequent chronic back pain. PURPOSE: To evaluate the long-term clinical and radiological outcome after nonoperatively treated thoracic or lumbar burst fractures in adults, with special attention to posttraumatic radiological disc height reduction. STUDY DESIGN: Case series. PATIENT SAMPLE: Sixteen men with a mean age of 31 years (range, 19-44) and 11 women with a mean age of 40 years (range, 23-61) had sustained a thoracic or lumbar burst fracture during the years 1965 to 1973. Four had sustained a burst fracture Denis type A, 18 a Denis type B, 1 a Denis type C, and 4 a Denis type E. Seven of these patients had neurological deficits at injury, all retrospectively classified as Frankel D. OUTCOME MEASURES: The clinical outcome was evaluated subjectively with Oswestry score and questions regarding work capacity and objectively with the Frankel scale. The radiological outcome was evaluated with measurements of local kyphosis over the fractured segment, ratios of anterior and posterior vertebral body heights, adjacent disc heights, pedicle widths, sagittal width of the spinal canal, and lateral and anteroposterior displacement. METHODS: From the radiographical archives of an emergency hospital, all patients with a nonoperatively treated thoracic or lumbar burst fracture during the years 1965 to 1973 were registered. The fracture type, localization, primary treatment, and outcome were evaluated from the old radiographs, referrals, and reports. Twenty-seven individuals were clinically and radiologically evaluated a mean of 27 years (range, 23-41) after the injury. RESULTS: At follow-up, 21 former patients reported no or minimal back pain or disability (Oswestry Score mean 4; range, 0-16), whereas 6 former patients (of whom 3 were classified as Frankel D at baseline) reported moderate or severe disability (Oswestry Score mean 39; range, 26-54). Six former patients were classified as Frankel D, and the rest as Frankel E. Local kyphosis had increased by a mean of 3 degrees (p<.05), whereas the discs adjacent to the fractured vertebrae remained unchanged in height during the follow-up. CONCLUSIONS: Nonoperatively treated burst fractures of the thoracic or lumbar spine in adults with or without minor neurological deficits have a predominantly favorable long-term outcome, and there seems to be no increased risk for subsequent disc height reduction in the adjacent discs.     

上胸椎骨折手术治疗方法的探讨

延迟性脑脊液鼻漏病理机制及诊治探讨

目的总结15例经手术治疗的延迟性脑脊液鼻漏的临床资料,探讨脑脊液鼻漏的病理机制及其与诊断治疗的关系。方法本组共15例脑脊液鼻漏患者,其中颅底骨折13例,自发性1例和垂体瘤术后1例。重点分析术前CTMRI扫描,术中所见,以及疗效三者之间的关系。结果术中见14例患者神经组织疝入鼻窦,垂体瘤术后鼻漏为鞍上池下疝,其中后7例的CT扫描显示骨缺损,MRI显示神经组织下疝与术中所见完全一致。15例术后14例治愈,1例无效,无手术并发症。结论神经组织或鞍上池经颅底缺损疝入鼻窦为外伤后或自发性脑脊液鼻漏不能自愈的病理机制的重要环节,由于上述组织的疝入,导致粘膜、硬膜、蛛网膜难以修复。冠状CT扫描和MRI可确定瘘口部位,如果冠状CT有骨缺损,MRI检查相应部位有脑组织下疝,应积极早期手术治疗。     

纸夹板内收位固定与石膏外展位固定治疗Bennett骨折的随机对照试验

目的：研究比较纸夹板内收位固定与石膏外展位固定治疗Bennett骨折的疗效差异。方法：选择2005年10月至2007年4月门诊就诊的70例Bennett骨折患者，按区组随机的方法分为试验组35例（纸夹板内收位固定）和对照组35例（石膏外展位固定）进行治疗。骨折达到临床愈合拆除固定后，对患者进行为期6个月的随访观察。分别于骨折后6、8、12、16、20及24周按改良的Gabriele评分系统对其患手功能进行量化评分比较。结果：两组的优良率在8、12、16及20周时比较试验组优于对照组，差异有统计学意义（P〈0．05）；6周和24周时比较差异无统计学意义（P〉0．05）。两组在功能评分方面，8、12、16、20及24周时比较试验组高于对照组，差异有统计学意义（P〈0．05）；6周时积分差异无统计学意义（P〉0．05）。结论：在Bennett骨折的治疗中，纸夹板内收位固定与石膏外展位固定相比能明显加快患手功能的恢复，而且固定轻便、舒适，患者易于接受，可以作为一种有效的固定方法在临床推广。
