The Paprosky system uses preoperative radiographs to classify defects by the amount of acetabular component migration and the status of the acetabular supporting structures including the anterior and posterior columns, the superior weightbearing dome, …

The Paprosky classification offers a simple categorization of proximal femoral bone loss founded on clinical and biomechanical evidence. However, even with such a system, the severity of bone loss can be underestimated.

2016年11月30日 · • The Paprosky classification is based on the anteroposterior (AP) pelvis radiograph. It uses four separate criteria to determine the classification: superior migration of the cup, the amount of ischial osteolysis, the amount of teardrop osteolysis, and the position of the cup relative to Kohler’s line.

- Classifications: - type I: rim is intact w/ no significant distortion of the rim - acetabulum is hemispherical but there may be small focal areas of contained bone loss; - anterior and posterior columns are intact; - hemispherical cementless implant is almost completely supported by native bone and has full inherent stability;

1, 14] (Fig. 2; Table 1). The Paprosky classification is divided into three types with increasingly severe degrees of bone loss; Types 2 and 3 are further divid d into subtypes (Fig. 1). Type 1 defects have minimal focal bone loss with maintenance of the hemispheri

2022年11月23日 · We asked two major questions: (1) What are the clinical and radiological results of the iliac extended fixation technique in patients with Paprosky type III superior acetabular defects? (2) Are there any preoperative, intraoperative, and postoperative differences between the two groups of IIEF and EIEF patients?

The objective of this study was to review mid-term cases of severe bone defect (Paprosky type III) treated with a bone allograft and ring Bursch-Schneider anti-protrusion cage (BSAC). Methods: A retrospective consecutive series review of the first 23 complex acetabular reconstructions performed between 2006 and 2011 was conducted.

We propose a novel classification system with the goal of simplifying and standardizing the management of protrusio acetabuli in the context of modern total hip arthroplasty.
