COLUMN FRACTURES The anterior column extends from the pubic symphysis, along the superior pubic ramus, across the acetabulum to the anterior part of the ilium. On the x-ray it is shown in profile by the iliopectineal line in the oblique view. Anterior column fractures are uncommon, do not involve the weightbearing area and have a good prognosis. The posterior column extends from the ischium, across the posterior aspect of the acetabular socket to the sciatic notch and the posterior part of the innominate bone. In an iliac oblique x-ray it is seen in profile as the ilioischial line. A posterior column fracture usually runs upwards from the obturator foramen into the sciatic notch, separating the posterior ischiopubic column of bone and breaking the weightbearing part of the acetabulum. It is usually associated with a posterior dislocation of the hip and may injure the sciatic nerve. Treatment is more urgent and usually involves internal fixation to obtain a stable joint. ---from 《Apley’s System of Orthopaedics and Fractures》 重点词汇整理： profile /ˈproʊfaɪl/n. 侧面；轮廓；外形；剖面；简况 iliopectineal line 髂耻线 Anterior column fractures are uncommon, do not involve the weightbearing area and have a good prognosis.前柱骨折不常见，不累及负重区，预后良好。 ischium /'ɪskɪəm/n.
