股骨远端骨折术后骨不连原因分析及处理

目的探讨股骨远端骨折术后骨不连的原因及处理方法。方法分析11例股骨远端骨折术后骨不连的原因,均再次手术、植骨、解剖钢板内固定。结果10例获1年1个月-3年8个月随访,骨不连均愈合,愈合时间11.6-19.8个月（平均16.9个月）。无钢板、螺钉松动断裂。膝关节功能按Kolment评分标准：优3例,良5例,差2例。结论内固定不当、骨缺损尤其是内侧骨缺损未充分植骨修复、术后管理不当等是导致骨不连的重要因素。植骨、解剖钢板内固定是治疗股骨远端骨折术后骨不连较适宜的方法。

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.

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。
