An 82-year-old man sustained an acetabular fracture on the left side involving the anterior and posterior columns after falling from a bicycle (Figures 1 and 2).
Three-dimensional computed tomography scan of the fracture showing displacement of both columns and impaction of the femoral head.

An 82-year-old man sustained an acetabular fracture on the left side involving the anterior and posterior columns after falling from a bicycle (Figures 1 and 2).
Postoperative radiographs. Both columns have been reduced and plated.

We then used the Kocher-Langenbeck approach to access the posterior column, wherein the overall fixation was neutralized by the reconstruction plate contoured to accommodate the shape of the posterior column (Figure 3).

At the time of the final follow-up, 18 months postoperatively, the patient was able to perform stair climbing without pain and the radiograph showed stable fixation without osteoarthritic change (Figure 4).
Pre- and postoperative coronal computed tomography scans. (a) There are extensive bone defects on the acetabular loading surface. (b) Immediately after surgery. (c) Three months after surgery: the scan shows that Affinos  transplanted into the bone defect area has not been absorbed (arrow). (d) Eighteen months after surgery: absorption and bone fusion around the artificial bone were observed (triangle).
