[目的]研究Graf超声检查方法在诊断婴幼儿发育性髋关节异常中的临床价值。[方法]选择2010年8月～2012年9月来本院就诊临床疑似发育性髋关节异常的婴幼儿108例(216个髋关节),其中男婴幼儿35例,女婴幼儿73例;年龄8 d～6个月,平均45 d;依据Graf常规超声检查法,通过测量α、β角度,评估双侧髋关节髋臼形态、股骨头位置,髋臼与股骨头的关系,并对髋关节进行分型。[结果]I型186个(86.1%),Ⅱa型10个(4.9%),Ⅱb型12个(6.0%),Ⅱc型2个(1.1%),Ⅲ型4个(1.9%),IV型2个(1.0%),D型未见。骨顶线夹角α≥60°时,说明髋关节的骨性关节凹发育较好,关节凹较深,股骨头不易脱出关节,骨顶线夹角α﹤60°时,说明髋关节骨性关节凹发育不良,关节凹较浅或较平,股骨头易脱出关节,另外,男婴幼儿髋臼α角度较女婴幼儿大,两者差异有统计学意义(P﹤0.05),提示性别对骨性髋臼发育有影响,双侧比较左侧和右侧髋关节α角右侧较左侧大(P﹤O.05),提示左侧较右侧髋臼发育差。[结论]超声检查法能够早期准确评价婴幼儿髋关节发育情况,并对髋关节发育不良的治疗过程进行随访观察。
[Objective] To study the clinical value of Graf ultrasonography in the diagnosis of developmental hip dysfunction in infants and toddlers. [Methods] From August 2010 to September 2012, 108 infants and toddlers (216 hips) with clinically suspected developmental dysplasia in our hospital were selected. Among them, 35 were male infants and 73 female infants; age 8 d ~ 6 months, an average of 45 d; according to Graf routine ultrasound examination, by measuring the angle of α, β acetabulum bilateral acetabulum assessment of the shape, the position of the femoral head, acetabulum and femoral head, and the hip For typing. [Results] 186 (86.1%) were type I, 10 (4.9%) were type IIa, 12 (6%) were type IIb, 1.1% were type IIc and 1.9% 2 (1.0%), D-type did not see. Osteoclampsia angle α ≥ 60 °, indicating good development of hip joint osteoarthritis, deep joint recess, the femoral head is not easy to prolapse, the angle between the top of the bone α <60 °, indicating that the bony osteoarthritis Joint concave dysplasia, shallow or flat joint recess, femoral head easy to prolapse of the joint, in addition, baby boy infant acetabular angle α is larger than infant girls, the difference was statistically significant (P <0.05), suggesting that gender Osteoid acetabular development is affected, both sides of the left and right hip angle α right than the left side of the larger (P <0.05), suggesting that the left side of the right side of the acetabular poor development. [Conclusion] Ultrasonography can accurately evaluate the development of hip joint in infants and young children early and follow-up observation of the treatment of hip dysplasia.
