摘要
背景:全髋关节置换髋臼杯的位相、大小型号选择不当可导致髋臼假体固定失败。目的:运用多层螺旋CT分析髋臼位相与开口形态学参数的关系。方法:选择髋关节正常者63例126髋,在CT三维重组VR图像上去除股骨头观察髋臼前后壁的形态,在MPR标准冠状位和横轴位上测量髋臼中心层面髋臼前后壁高度差、前后径、前倾角、上下径、横径、外展角,比较左右侧、男女性别及相同性别不同年龄参数的差异,通过相关和回归分析得出髋臼位相与开口形态学参数的关系。结果与结论:髋臼前唇形态分为曲线型(54/126,44.44%)、平直型(30/126,23.80%)、不规则型(22/129,17.46%)及成角型(18/126,14.28%)。不同侧别和不同年龄髋臼位相及开口形态学参数差异无显著性意义(P>0.05)。男性的髋臼上下径、前后径明显大于女性(P<0.01),但前倾角和外展角在不同性别间差异无显著性意义(P>0.05)。男女性前倾角与髋臼前后壁高度差、上下径与前后径均呈显著正相关,外展角与横径呈明显负相关。前倾角与前后壁高度差高度相关,与前后径呈明显低相关,数值上前倾角≈前后壁高度差;男性前后径与上下径、横径呈明显正相关,女性外展角与前后径呈明显正相关。其余参数相关不明显。髋臼位相与开口形态学参数有一定相关性,两者的相互匹配,对髋臼假体的设计及全髋关节置换计划的制定具有指导意义。
BACKGROUND： The improper selection of phase and sizes of acetabular cup of total hip arthroplasty can cause fixation failure of the acetabular component.OBJECTIVE： To analyze the interrelationship between location phase and opening morphologic parameters of acetabular with multislice CT.METHODS： The normal hip joints of 63 patients （126 hips） were selected in the study, removed the femoral head to observe the morphology of the acetabular anterior and posterior wall on CT reformation VR image,the center of the acetabulum levels of the MPR standard coronal and axial CT image were measured, including acetabular ridge height difference posterior and anterior, anteroposterior diameter, anteversion angle, suprainferior diameter, transverse diameter, the abduction angle, and the difference between left and right side, male and female, as well as the parameters with the same gender and different ages were analyzed. The correlation and regression analysis was used to draw the interrelationship between location phase and opening morphologic parameters of acetabular rim.RESULTS AND CONCLUSION： Anterior acetabular ridge shapes were divided into curved type （541126, 44.44%）, linear type （30/126, 23.80%）, irregular angles type （22/129, 17.46%） and angled type （18/126, 14.28%）.There was no significant difference of the location phase and opening morphologic parameters of acetabular rim between different sides and ages （P 〉 0.05）. The suprainferior diameter and anteroposterior diameter of male patients were significantly larger than those in female patients （P 〈 0.01 ）, but there were no significant differences of abduction angle and anteversion angle between different genders （P 〉 0.05）. The anteversion angle of male and female patients was positive correlated with acetabular ridge height difference posterior and anterior and suprainferior diameter, but the abduction angle was negative correlated with the transverse diameter. The anteversion angle and the acetabular ridge height difference posterior and anterior was highly correlated, significantly lowly correlated with the anteroposterior diameter, and the anteversion angle≈acetabular ridge height difference posterior and anterior numerically; the male anteroposterior diameter was positive correlated with suprainferior diameter and transverse diameter, the female abduction angle was significantly positive correlated with anteroposterior diameter. The remaining parameters were not obvious. There was correlation between acetabular opening morphological parameters and location phase which matched with each other and had guidance effect on the design of acetabular prosthesis and formulation of total hip arthroplasty.
