髋臼

Acetabula are outlined, and center of graity is at X. B, Center of graity, X, is anterior to S2 ertebra, although center of graity is not fixed and changes with moement of upper body with respect to pelis.

髋臼已标出，重心位于X点。B：重心X位于S2椎体前方，尽管重心并不固定，可随躯干相对于骨盆的运动发生改变。

Methods From March 1994 to December 2002, on the basis of the ordinary operative method, Pemberton method was improved for 48 cases of DDH 49 articulatio coxae which had superficial and small acetabula but big heads of femur. Osteotomy points were moved higher to enlarge area of bone flap turned over. A piece of full thickness ilium including periosteum was removed as a free bony graft. Capsula articularis growing thicker was made into 2 layers, of which the inner layer was used to tighten articularis and the outer layer was used to stabilize bone flap.

1994年3月～2002年12月，对DDH髋臼浅而小、股骨头大的48例49个髋关节，在通常术式的基础上，对Pemberton截骨术式进行改良，将截骨点上移，扩大翻转骨瓣面积；取髂骨全层骨板连带附着的骨膜植骨；增厚的关节囊制成两层，内层紧缩关节，外层稳定骨瓣。

Results All patients were followed up for 18 months to 5 years, the function of articulatio coxae and degree of bony union, inclusion area to head of femur and ischemic necrosis of femoral head were observed through X-ray.

术后观察髋关节功能，X线片显示的截骨愈合程度、髋臼对股骨头包容程度及有无股骨头坏死等。

The osteotomies around the acetabulum hae been described5,9,10 Fig.

在图2中描述了围绕髋臼所做的截骨术。

Methods Along acetabular turn osteotomies with downward turn.

目的 探讨治疗成人髋臼发育不良的新方法。

Methods Twelve half pelvises were classified into 3 groups randomly.

笔者选用髋臼横断骨折常用的3种内固定方法进行生物力学稳定性比较。

Infection must be suspected if part of the subchondral bone of the acetabulum or femoral head is eroded or if bone has been resorbed about an internal fixation deice.

如果髋臼或股骨头软骨下骨被侵蚀或内固定物周围骨质吸收，应除外感染。

Remove the death bone of the femoral head,repair acetabulum,three Kirschner or lag screw bore into from the head of femur,parallel to neck of femur,present equilateral triangle.Filling up the bone cement in the bipolar hemiarthroplasty,set enters neck of femur,form the new head of femur.

清除股骨头死骨，修整髋臼，从股骨头与股骨颈平行呈品字型钻入3枚克氏针或拉力螺钉，在人工股骨头中填满骨水泥后套入股骨颈形成新的股骨头。

Objective: To study anatomical basis for the placement of lag screw in the acetabular anterior column.

目的：探讨髋臼前柱拉力螺钉内固定的解剖学基础。

Objective:To study the best entry points, direction and length of screw in acetabular anterior column lag screw technique.

目的：研究髋臼前柱拉力螺钉内固定技术中螺钉的最佳进钉点、方向和长度。
