【摘要】：背景:T?nnis分型是發(fā)育性髖關(guān)節(jié)發(fā)育不良脫位程度的常用分型方法,但其應(yīng)用受股骨頭骨骺核是否骨化的限制。針對(duì)這一缺點(diǎn),國(guó)際髖關(guān)節(jié)發(fā)育不良協(xié)會(huì)(International Hip Dysplasia Institute,IHDI)提出了新的分型方法(IHDI分型),但I(xiàn)HDI分型與相對(duì)應(yīng)的發(fā)育性髖關(guān)節(jié)發(fā)育不良病理改變?nèi)绾?尚無(wú)報(bào)道。目的:分析IHDI分型與髖關(guān)節(jié)MRI病理形態(tài)的相關(guān)性。方法:回顧性分析發(fā)育性髖關(guān)節(jié)發(fā)育不良患兒的術(shù)前影像資料共65例(89髖),平均年齡20.4個(gè)月。按IHDI標(biāo)準(zhǔn)進(jìn)行分型,并在MRI圖像上,觀察頭臼關(guān)系、盂唇的形態(tài),并測(cè)量軟骨性髖臼指數(shù),分析IHDI分型與髖關(guān)節(jié)病理形態(tài)的相關(guān)性。結(jié)果與結(jié)論:(1)IHDI分型與年齡呈正相關(guān)(r=0.456,P0.001);(2)隨IHDI分型的增加,頭臼關(guān)系由部分形成關(guān)節(jié)逐漸過(guò)度到完全不形成關(guān)節(jié),軟骨髖臼指數(shù)也明顯增大(P=0.028);(3)Ⅰ型髖盂唇均為外翻形,而內(nèi)翻或騎跨形的盂唇在Ⅱ型髖中占60%,Ⅲ型中占86%,Ⅳ型髖為97%;(4)結(jié)果表明,發(fā)育性髖關(guān)節(jié)發(fā)育不良隨IHDI分型的增加,頭臼間的覆蓋率逐漸減小,軟骨性髖臼緣發(fā)育不良及盂唇內(nèi)翻程度逐漸加重。了解IHDI分型與髖關(guān)節(jié)病理形態(tài)的相關(guān)性對(duì)指導(dǎo)發(fā)育性髖關(guān)節(jié)發(fā)育不良治療具有重要意義。
[Abstract]:Background: T?nnis classification is a common method for the classification of developmental dysplasia of hip, but its application is limited by whether the femoral head epiphyseal nucleus is ossified or not. In order to overcome this shortcoming, the International Association of Hip dysplasia (International Hip Dysplasia Institute,IHDI) proposed a new classification method (IHDI classification), but there is no report on the pathological changes between IHDI classification and the corresponding developmental hip dysplasia. Objective: to analyze the correlation between IHDI classification and MRI histopathology of hip joint. Methods: the preoperative imaging data of 65 cases (89 hips) with developmental dysplasia of hip were retrospectively analyzed, with an average age of 20.4 months. According to IHDI criteria, the relationship between head and labium and the shape of labium were observed on MRI images. The articular acetabular index was measured, and the correlation between IHDI classification and pathological morphology of hip was analyzed. Results and conclusion: (1) there was a positive correlation between IHDI classification and age (r = 0.456P 0.001); (2) with the increase of IHDI classification, the acetabular relationship between the head and the acetabulum increased gradually from partial joint formation to no joint formation, and the acetabular index of cartilage increased significantly (P0. 028). (3) the pelvic lips of type 鈪，
