Reconstruction of acetabular deficiencies- Paprosky classification

Reconstruction of acetabular deficiencies- Paprosky classification 


Paprosky et al. developed a classification system based on preoperative radiographs andintraoperative findings with the various classes determinedby the position of the acetabular component relative to the host acetabulum and with the status of the host bone defined by bony landmarks. This system is helpful in preoperativeplanning, because the defects encountered at surgery often can be predicted by the class of deficiency (Fig. 3-154 and Table 3-7)

Anteroposterior and lateral radiographs, Judet views, and CT scans are often helpful in evaluating the acetabulardeficits preoperatively. Ultimately, the degree of deficiency isdetermined intraoperatively when loose components are removed and trial revision components are placed. Preoperative templating is useful to anticipate the size of the component required and the need for bone grafts after the new component is placed in the proper location.
