【摘要】:目的 分析并探讨多层螺旋CT及后重建技术在胫骨平台骨折中的诊断及对Schatzker分型的应用价值,并对DR平片、螺旋CT、 MPR、VR后处理图像在胫骨平台骨折诊断中的价值进行比较、分析,为临床治疗提供更加可靠、直观的依据。 材料与方法 收集泰山医学院附属医院2010年2月-2013年2月经手术证实的胫骨平台骨折病例211例,其中男126例,女85例,年龄11-77岁,平均年龄40岁。右侧胫骨平台骨折81例,左侧胫骨平台骨折129例,,双侧胫骨平台骨折1例。所有病例均行膝关节正侧位DR平片(其中1例伤势较重,无法转动体位,只拍摄正位片)、螺旋CT平扫检查及其MPR、VR图像后处理,由放射科2位高年资医师分别进行Schatzker分型,比较不同影像学检查对胫骨平台骨折Schatzker分型的差异,分析CT及MPR、VR后处理检查在胫骨平台骨折的诊断价值。同时对各型胫骨平台骨折合并髁间隆突骨折、腓骨小头骨折进行比较。 结果 在所有211例212侧胫骨平台骨折中,DR平片Schatzker分型正确169侧,分别是Ⅰ型19侧;Ⅱ型31侧;Ⅲ型13侧;Ⅳ型27侧;Ⅴ型52侧;Ⅵ型27侧。多层螺旋CT Schatzker分型正确205侧,Ⅰ型31侧;Ⅱ型41侧;Ⅲ型22侧;Ⅳ型32侧;Ⅴ型52侧;Ⅵ型27侧。DR平片、多层螺旋CT胫骨平台骨折分型总符合侧数分别为169侧、205侧,占手术后分型比率分别为79.7%、96.7%,DR平片与多层螺旋CT相比较,χ2=25.338,P0.001,差异有统计学意义,因此,对胫骨平台骨折Schatzker分型,多层螺旋CT准确率明显比DR平片高;DR平片与多层螺旋CT正确分型侧数占术后诊断比分别为,Ⅰ型:9.0%、14.6%,两种检查方法比较P=0.001,P0.05有显著差异,Ⅱ型:14.6%、19.3%,两种检查方法比较P=0.001,P0.05有显著差异,Ⅲ型:6.1%、10.4%,两种检查方法比较P=0.005,P0.05,有显著差异,Ⅳ型:12.7%、15.1%,两种检查方法比较P=0.020, P0.05,有显著差异,Ⅴ型、Ⅵ型没有改变;因此多层螺旋CT对胫骨平台骨折Schatzker分型的Ⅰ型、Ⅱ型、Ⅲ型、Ⅳ型敏感性最高,优势明显。比较I~Ⅵ型各分型组间伴髁间隆突骨折的差异性(P0.001)和合并腓骨小头骨折的差异性(P0.001),差异有显著性意义。 结论 普通X线平片的诊断经验丰富,使用起来快捷、方便,能显示胫骨平台骨折的大体情况,对大多数的胫骨平台骨折能够诊断,一直是胫骨平台骨折影像学检查的首选方法。但是胫骨平台骨折十分复杂,普通X线平片不能提供临床需要的尽可能完善的信息,需要多层螺旋CT等其他影像检查方法的辅助;多层螺旋CT平扫及重建技术能全面的、多方位及立体的显示胫骨平台骨折,有效地避免漏诊,能更准确的对胫骨平台骨折进行Schatzker分型,可以发现X线平片不能发现的腓骨小头及髁间隆突等伴随骨折,为临床医师制定合适的治疗方案及治疗后复查提供依据。
[Abstract]:PurposeThe value of multi-slice spiral CT and post-reconstruction in the diagnosis of tibial plateau fracture and its application to Schatzker classification were analyzed. The value of Dr flat-film, spiral CT and MPR VR post-processing images in the diagnosis of tibial plateau fracture were compared and analyzed.To provide a more reliable and intuitive basis for clinical treatment.Materials and methodsFrom February 2010 to February 2013, 211 cases of tibial plateau fracture confirmed by operation in affiliated Hospital of Taishan Medical College were collected, including 126 males and 85 females, aged 11-77 years with an average age of 40 years.81 cases of right tibial plateau fracture, 129 cases of left tibial plateau fracture and 1 case of bilateral tibial plateau fracture.All the patients underwent Dr plain radiography (one of them was seriously injured, unable to turn his body position), only positive position film was taken, helical CT plain scan and post-processing of MPR-VR images were performed. Schatzker typing was performed by two senior radiologists in radiology department.To compare the difference of Schatzker classification of tibial plateau fracture with different imaging examination, and to analyze the diagnostic value of CT and MPR VR postprocessing in tibial plateau fracture.At the same time, the fracture of tibial plateau combined with intercondylar protuberance fracture and fibular head fracture were compared.ResultIn all 211 patients with 212 sides of tibial plateau fracture, the Schatzker typing of Dr plain film was correct in 169 sides, including 19 of type 鈪
