USE OF HELICAL COMPUTED TOMOGRAPHY FOR THE ASSESSMENT OF ACETABULAR OSTEOLYSIS AFTER TOTAL HIP ARTHROPLASTY

Abstract

Helical computed tomography with metal-artifact minimization is more sensitive for identifying and quantifying osteolysis after total hip arthroplasty than is plain radiography. Since computed tomography scans show both the extent and the location of lytic lesions, they are useful to guide treatment decisions as well as to assist in planning for surgical intervention, when needed, in patients with suspected osteolysis.
