【摘要】:目的 分析并探討多層螺旋CT及后重建技術(shù)在脛骨平臺(tái)骨折中的診斷及對(duì)Schatzker分型的應(yīng)用價(jià)值,并對(duì)DR平片、螺旋CT、 MPR、VR后處理圖像在脛骨平臺(tái)骨折診斷中的價(jià)值進(jìn)行比較、分析,為臨床治療提供更加可靠、直觀的依據(jù)。 材料與方法 收集泰山醫(yī)學(xué)院附屬醫(yī)院2010年2月-2013年2月經(jīng)手術(shù)證實(shí)的脛骨平臺(tái)骨折病例211例,其中男126例,女85例,年齡11-77歲,平均年齡40歲。右側(cè)脛骨平臺(tái)骨折81例,左側(cè)脛骨平臺(tái)骨折129例,,雙側(cè)脛骨平臺(tái)骨折1例。所有病例均行膝關(guān)節(jié)正側(cè)位DR平片(其中1例傷勢(shì)較重,無(wú)法轉(zhuǎn)動(dòng)體位,只拍攝正位片)、螺旋CT平掃檢查及其MPR、VR圖像后處理,由放射科2位高年資醫(yī)師分別進(jìn)行Schatzker分型,比較不同影像學(xué)檢查對(duì)脛骨平臺(tái)骨折Schatzker分型的差異,分析CT及MPR、VR后處理檢查在脛骨平臺(tái)骨折的診斷價(jià)值。同時(shí)對(duì)各型脛骨平臺(tái)骨折合并髁間隆突骨折、腓骨小頭骨折進(jìn)行比較。 結(jié)果 在所有211例212側(cè)脛骨平臺(tái)骨折中,DR平片Schatzker分型正確169側(cè),分別是Ⅰ型19側(cè);Ⅱ型31側(cè);Ⅲ型13側(cè);Ⅳ型27側(cè);Ⅴ型52側(cè);Ⅵ型27側(cè)。多層螺旋CT Schatzker分型正確205側(cè),Ⅰ型31側(cè);Ⅱ型41側(cè);Ⅲ型22側(cè);Ⅳ型32側(cè);Ⅴ型52側(cè);Ⅵ型27側(cè)。DR平片、多層螺旋CT脛骨平臺(tái)骨折分型總符合側(cè)數(shù)分別為169側(cè)、205側(cè),占手術(shù)后分型比率分別為79.7%、96.7%,DR平片與多層螺旋CT相比較,χ2=25.338,P0.001,差異有統(tǒng)計(jì)學(xué)意義,因此,對(duì)脛骨平臺(tái)骨折Schatzker分型,多層螺旋CT準(zhǔn)確率明顯比DR平片高;DR平片與多層螺旋CT正確分型側(cè)數(shù)占術(shù)后診斷比分別為,Ⅰ型:9.0%、14.6%,兩種檢查方法比較P=0.001,P0.05有顯著差異,Ⅱ型:14.6%、19.3%,兩種檢查方法比較P=0.001,P0.05有顯著差異,Ⅲ型:6.1%、10.4%,兩種檢查方法比較P=0.005,P0.05,有顯著差異,Ⅳ型:12.7%、15.1%,兩種檢查方法比較P=0.020, P0.05,有顯著差異,Ⅴ型、Ⅵ型沒(méi)有改變;因此多層螺旋CT對(duì)脛骨平臺(tái)骨折Schatzker分型的Ⅰ型、Ⅱ型、Ⅲ型、Ⅳ型敏感性最高,優(yōu)勢(shì)明顯。比較I~Ⅵ型各分型組間伴髁間隆突骨折的差異性(P0.001)和合并腓骨小頭骨折的差異性(P0.001),差異有顯著性意義。 結(jié)論 普通X線平片的診斷經(jīng)驗(yàn)豐富,使用起來(lái)快捷、方便,能顯示脛骨平臺(tái)骨折的大體情況,對(duì)大多數(shù)的脛骨平臺(tái)骨折能夠診斷,一直是脛骨平臺(tái)骨折影像學(xué)檢查的首選方法。但是脛骨平臺(tái)骨折十分復(fù)雜,普通X線平片不能提供臨床需要的盡可能完善的信息,需要多層螺旋CT等其他影像檢查方法的輔助;多層螺旋CT平掃及重建技術(shù)能全面的、多方位及立體的顯示脛骨平臺(tái)骨折,有效地避免漏診,能更準(zhǔn)確的對(duì)脛骨平臺(tái)骨折進(jìn)行Schatzker分型,可以發(fā)現(xiàn)X線平片不能發(fā)現(xiàn)的腓骨小頭及髁間隆突等伴隨骨折,為臨床醫(yī)師制定合適的治療方案及治療后復(fù)查提供依據(jù)。
[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
