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.

Component fixation on the acetabular side is not as much of a problem because of the simpler geometry and loading configuration. It is generally accepted that hemispheric component design is preferable and immediate implant stability can be achieved by using screws or spikes in the porous coated implants. The authors reviewed 130 primary noncemented porouscoated, press fit acetabular component in 110 patients; 84 were AML (Anatomical Medullary Locking) and 46 were HarrisGalante acetabular component. Radiologic analysis at a minimum of 3 years(average 4.5 years) was done with special regards to the vertical and medial migration, screw size and numbers, change of the radiolucent line and its zone with its fate and acetabular cup angles on the acetabular component by the 2 observers. Progressive radiolucent line at the component-bone intersurface were found in 14 cases(11%), frequently located in zone I and zone I & II. No significant vertical, medial migration and change of the acetabular cup angle were found. No screw and spike failure had occurred. No component had to be revised because of loosening. As a whole, in our 3-years experience we report excellent results with porous coated acetabular component although it dose not ensure long-term sucess.

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.
