Objective To compare the navigational and traditional dynamic hip screw (DHS) fix-ations in the treatment of intertrochanteric fractures in elderly patients. Methods A retrospective study was conducted to analyze the elderly patients with intertrochanterie fracture who had been treated in our de-partment from April 2005 to April 2007 and whose clinical data were complete. Enrolled in the present study were 25 cases that had received navigational DHS fixation and 31 cases who had received traditional DHS fixation. In navigational group, there were 10 males and 15 females, with an average age of 82. 1 years. They were 14 eases of Evans type Ⅰ and 11 Evans type Ⅱ. In traditional group, there were 12 males and 19 fe-males, with an average age of 82. 8 years. They were 16 cases of Evans type Ⅰ and 15 Evans type Ⅱ. The 2 groups were compared in incision length, operation time, bleeding volume, X-ray exposure time, bed-ridden time, medical and implant complications, and one-year functional recovery. Results In navigational group, 23 patients were followed for 11 to 20 (average, 14) months and 2 were lost. In traditional group, 30 patients were followed up for 14 to 23 (average, 18) months and 1 died from cardiovascular disease within 1 year. Compared with traditional group, navigational group had a smaller incision, less blood loss, shorter bed-ridden time and less X-ray exposure time, a higher rate of fracture healing at 3 months, with statistically significant differences (P <0.05). The Harris hip function scores at postoperative 1 year were of no significant difference between the 2 groups (P > 0.05) . In navigational group there were 3 medical and 1 implant complications. In traditional group there were 9 medical and 5 implant complications. There was no significant difference between the 2 groups (P > 0.05). Conclusion In the treatment of intertrochanteric fractures for the elderly patients, the navigational DHS fixation is superior to traditional DHS fixation due to its ad-vantages of smaller incision, less blood loss, shorter bed-ridden time, faster fracture healing and betterfunctional recovery. 相似文献

目的 探讨胸腰椎压缩骨折经伤椎或者跨椎椎弓根钉内的固定效果.方法 对本院收治的25例胸腰椎压缩骨折患者,利用椎管的环形减压以及短节段的椎弓根螺钉系统实行固定,采取在经伤椎单侧或者双侧椎弓根固定方法.结果 随机访问术后1~4年25例患者状况,术后均未出现伤口感染或神经损伤等问题.距患者术后7d的X线检查显示,脊柱Cobb's已经从损伤后的24°恢复到术后7d的2.8°.经CT显示,患者伤椎周边的骨皮质较为完整,且椎管内的骨块恢复较好,解除椎管狭窄问题.术后VAS评分由8分到2分(P<0.05).结论 通过实行胸膜椎压缩骨折经伤椎或跨椎椎弓根钉内固定方法,对于骨折复位治疗效果良好,可重新恢复椎体高度,提高脊柱抗压性与稳定性,减少一系列并发症的产生,减轻患者痛苦,具有临床应用价值. 相似文献
