Central Fractures of the Acetabulum

¹ Campbell Foundation and the University of Tennessee College of Medicine, Memphis

1. Open reduction of central fractures of the acetabulum is technically feasible. The primary objective is to restore the weight-bearing vault. Improvement of symmetry of the pelvis or reduction of the posterior portion of the acetabulum, if achieved as well, is a dividend.

2. Detailed classification of these fractures is neither possible nor necessary. A simple working rule divides them into two major types: horizontal, and vertical. The horizontal type is approached through an anterior incision ; the vertical, through a posterolateral incision.

3. Stereoscopic anteroposterior roentgenograms are essential to the correct interpretation of the fracture and to the correct choice of approach.

4. Following open reduction, after-care is greatly simplified, and morbidity is greatly diminished.

5. The results after open reduction are, to date, generally superior to those obtained in the past by the older methods of manipulation and traction.

6. Long-term studies of large series of patients will be necessary before the method can be fully evaluated.
