Total Hip Arthroplasty with a Cementless Acetabular Component and Impaction Bone Grafting for Dysplastic Osteoarthritis Complicated by Multiple Myeloma

Figure 2

Coronal computed tomography (CT) images prior to surgery (a–d) reveal  mm cortical defect of the quadrilateral plate and massive bone absorption lesions of the cancellous bone in the supraacetabular region, medial wall, and ischium. The roof and anterior/posterior walls of the acetabulum are intact. The acetabular bone loss was classified as a Harrington class II defect. Axial CT images (e) 13 years prior to surgery and (f) 1 month prior to surgery reveal that bone absorption lesions existed 13 years ago.
