In the surgical treatment of acetabular fractures, the anterior approach is used widely for anterior column fractures with or without posterior column fractures. This paper reviews the anterior approach for the anatomical reduction and rigid fixation of acetabular fractures: traditional ilioinguinal approach, modified Stoppa approach, and new Pararectal approach.

PURPOSE: The purpose of this study was to compare the two-dimensional with three-dimensional radiographic measurements of polyethylene liner wear in the Harris-Galante II acetabular cup. MATERIALS AND METHODS: We measured the polyethylene liner wear amount and the wear rate of 64 hips with Harris-Galante II acetabular cup by two methods: Livermore's method and modified Devane's method. We evaluated the relationships between the two methods. RESULTS: The average total amount of wear and the average wear rate are 0.86+/-1.01 mm and 0.18+/-0.20 mm/year using the two-dimensional method and 0.99+/-1.01 mm and 0.21+/-0.2 mm/year using three-dimensional method respectively. The amount of wear and the wear rate by the three-dimensional method was larger than those by the two dimensional method. CONCLUSION: The amount of polyethylene liner wear can be measured by the two-dimensional method because it is highly correlated with the amount that is measured by the three-dimensional method, since there was no differences between the two methods.

PURPOSE: To evaluate the configuration of the anterior column of the acetabulum and to develop a safe path for screw placement for it. Materials and methods: Ten embalmed cadaveric adult bony-hemipelvis specimen were obtained. Each specimen was sectioned at 1cm intervals, beginning at the level of the inferior border of the acetabulum. The plane of the cross-section was perpendicular to the anterior column. The projection of the medial acetabular boundary on the anterior column was determined by analysis of each cross-section. RESULTS: The average width of the anterior column at 1.0, 2.0 and 3.0 cm superior to the inferior acetabular boundary was 27.9+/-4.3, 31.7+/-3.6 and 35.2+/-4.9 mm, respectively. At 1.0 cm superior to the inferior margin of the acetabulum, the average medial angulation for 0.5, 1.0 and 1.5 cm entry points lateral to the pelvic brim were 26.7+9.1 degree, 37.9+/-6.5 degreeand 46.1+/-5.0 degree, respectively. At 2.0 cm superior to the inferior acetabular margin, the corresponding average medial angulation for 0.5, 1.0 and 1.5 cm entry points were 20.4+/-6.2 degree, 30.4+/-5.6 degree and 41.0+/-5.0 degree, respectively. At 3.0 cm superior to the inferior acetabular margin, these angles were found to be 19.5+/-3.8 degree, 30.5+/-5.1 degree and 40.8+/-4.6 degree, respectively. CONCLUSIONS: This anatomical analysis of the acetabulum shows that it is possible to develop a safe path for screw placement into the anterior column. And the data could be a useful guide line for plate and screws fixation of the anterior column of the acetabulum.
