多层螺旋CT对胫骨平台骨折的诊断价值

目的:评价MSCT在胫骨平台骨折的分类及制定合理的治疗方案方面的价值。方法:对24例常规X线平片或临床诊断为胫骨平台骨折的患者进行MSCT扫描,并对图像进行MPR、SSD和VR重建,对骨折的部位、范围、碎骨片的数量或骨折程度、胫骨平台受累情况、手术入路、骨质疏松程度及骨组织的缺损等做出评价。骨折的分型根据Swiss AO-ASIF法。结果:24例患者中有19例进行了手术治疗,术中所见与轴位MSCT和MPR、SSD及VR重建图像综合做出的诊断一致。结论:MSCT及其MPR、SSD、VR重建技术对于胫骨平台的骨折分型及术前评价有重要意义。     

16层螺旋CT及其三维重建与多平面重组在胫骨平台骨折诊断中的应用

目的探讨16层螺旋CT(16层SCT)及其三维重建(3-D)与多平面重组(MPR)在胫骨平台骨折诊断中的应用价值。方法39例胫骨平台骨折病例经膝关节常规X线平片检查后，采用16层SCT进行膝关节的多层面螺旋CT扫描，在工作站上作3D及MPR影像后处理，就胫骨平台骨折的平片与16层SCT影像进行比较及综合分析。结果39例胫骨平台骨折中，X线平片漏诊1例髁间隆突骨折、1例内髁骨折及1例双髁骨折，此3例(7．69％)平片漏诊的骨折均为16层SCT予以诊断。16层SCT的3-D影像可清晰显示胫骨平台骨折的立体形态；MPR影像则可明确显示胫骨平台内部的骨质损伤情况如骨折的具体部位、关节面碎裂及塌陷程度、骨折移位距离。结论16层SCT能够显示X线平片难于诊断的胫骨平台隐匿性骨折；3-D及MPR成像技术十分有利于全面观察胫骨平台骨折的形态变化，是16层SCT横轴位扫描的重要补充。     

有限切开固定治疗复杂胫骨平台骨折

目的探讨采用有限切开固定治疗复杂胫骨平台骨折的临床效果。方法采用间接复位有限切开固定治疗复杂胫骨平台骨折37例,SchatzkerⅣ型骨折采用前内侧小切口,T型钢板固定,SchatzkerⅤ、Ⅵ型骨折采用前外侧小切口联合后内侧切口,后内侧用1/3管型钢板固定支撑,外侧以高尔夫棒型钢板固定。结果随访6-30个月,37例均于12周内骨折愈合。所有患者均恢复了患肢的正常力线及患膝的骨性稳定。采用Sanders膝关节评分法评估疗效：优13例,良20例,可4例。结论有限切开固定治疗复杂胫骨平台骨折是一种安全有效的生物学固定方法,创伤小,骨折愈合快,可早期功能锻炼,膝关节功能恢复满意。     

螺旋CT三维重建影像在胫骨平台骨折诊疗中的价值

目的探讨螺旋CT三维重建影像在胫骨平台骨折诊断和治疗中的临床使用价值。方法2001年8月～2005年4月收集38例胫骨平台骨折分别行X线片和螺旋CT三维重建影像检查,对照术中所见,分析比较螺旋CT三维重建影像在临床诊断和治疗中的作用。结果X线片检查2例无法明确诊断,骨折分型错误6例;螺旋CT三维重建诊断、分型均正确。X线片与螺旋CT三维重建影像在确立诊断方面未见明显差异,但在分型和指导治疗方面,螺旋CT三维重建影像明显优于前者。结论螺旋CT三维重建影像能直观、立体地显示胫骨平台骨折的形态,有助于骨折的分型及治疗。     

Surgical treatment of complex tibial plateau fractures by closed reduction and external fixation. A review of 32 consecutive cases operated

Abstract Complex tibial plateau fractures are a challenge in trauma surgery. In these fractures it is necessary to anatomically reduce the articular part of the fracture and to obtain stable fixation. The aim of this study is to review the results of a surgical technique consisting of fluoroscopic closed reduction and combined percutaneous internal and external fixation. Thirty-two complex tibial plateau fractures in 32 patients were included. Twenty-one fractures were closed, 4 were open Gustilo grade I, 3 were Gustilo grade II and 4 were Gustilo grade III. The mean age was 37.8 years (range 21–64 years). Surgery was performed with patients in transcalcaneal traction and the knee flexed at 30° was used. Through a 1-cm incision centred over the tibial metaphysis of the tibia, a 3.2-mm hole was drilled in the antero-medial tibial aspect. The tibial plateau fracture fragments were elevated using either 1 or 2 curved Kirschner wires under fluoroscopy to control the reduction. Then the fragments were fixed with 2 cannulated AO screws inserted through small incisions into the medial aspect of the tibial plateau. Knee rehabilitation started postoperatively. Weight bearing started after 8–12 weeks depending upon the radiographic appearance. All external fixators were removed in outpatient facilities. All patients were clinically and radiographically evaluated at a mean follow-up of 48 months (range 38–57 months). Clinical results were evaluated according to the Knee Society clinical score. Average healing time was 24 weeks (range 18–29 weeks). In 1 patient a non-union occurred. This patient was treated with open reduction and plate fixation. In 2 patients a varus knee deformity occurred and a surgical correction was performed. There were no surgical complications. Mean knee range of motion was 105° (range 75–125°) and mean Knee Society clinical score was 89. Twenty-five results were scored as excellent, 4 good, 2 fair and 1 poor. Using this technique there is limited soft tissue damage and virtually no periosteum damage to the fracture fragments. However anatomical reconstruction of the joint can be obtained. Furthermore knee rehabilitation can be started immediately after surgery. We think that these factors were responsible for the optimal clinical long-term results.
