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.

经食管超声心动图在胸主动脉瘤介入治疗中的应用

血管内修复术创伤性小，可应用于治疗多种主动脉疾病，如动脉瘤和主动脉夹层。经食管超声心动图(TEE)对主动脉疾病很敏感。术前可通过TEE找到撕裂的内膜片、发现内膜破口、区分类型、区分真假腔及了解心脏状况。术中TEE用于引导导管插至正确位置、观察支架放置过程、监测心功能和室壁运动状况、评价手术疗效。术后随诊通过TEE观察支架内血流情况、检出并发症如内漏等。     

椎弓根固定结合椎体成形术治疗胸腰椎爆裂骨折

目的探讨椎弓根固定结合经椎弓根椎体内植骨行椎体成形术治疗胸腰椎爆裂骨折的疗效。方法采用椎管环形减压、短节段椎弓根螺钉系统固定结合经椎弓根椎体内植骨治疗胸腰椎爆裂骨折116例,其中93例获得随访。术前及术后随访行X线和CT检查,测量伤椎椎体中央高度值,比较植骨后椎体高度的恢复程度,同时观察植骨融合情况。采用配对t检验方法进行统计学分析。结果93例患者术后平均随访24.2个月,90%以上患者伤椎椎体高度恢复并维持良好,无塌陷。伤椎椎体中央高度值犤T12(3.14±0.41)cm,L1(3.33±0.34)cm犦与正常值犤(T12(3.26±0.38)cm,L1(3.47±0.61)cm)犦比较,差异无显著性意义(P>0.05)。未出现植骨操作引起的神经血管并发症。CT显示椎体内植骨块边缘模糊,融合良好,植骨块无吸收现象。结论后路椎管环形减压及内固定时,经伤椎椎弓根进行椎体内植骨行椎体成形术可恢复伤椎椎体高度,重建前、中柱的稳定性,预防术后椎体塌陷的发生。
