Sa. Jacobsson et al., STEM LOOSENING MORE COMMON WITH ITH THAN LUBINUS PROSTHESIS - A 5-YEAR CLINICAL AND RADIOGRAPHIC FOLLOW-UP OF 142 PATIENTS, Acta orthopaedica Scandinavica, 66(5), 1995, pp. 425-431
Out of a consecutive series of 169 cemented total hip arthroplasties,
77 Lubinus SP 2 and 65 ITH prostheses, were followed-up after 5 years
with clinical and radiographic assessments. Radiolucencies were common
er around the ITH titanium stem than around the Lubinus cobalt-chrome
stem. 6 of the ITH stems were considered as definitely loose, as compa
red to none of the Lubinus stems. Hitherto, 5 patients in the ITH grou
p have had revisions and 2 need revision because of loosening. The poo
rer performance of the cemented ITH stem may be due to an unfavorable
combination of design and material properties.
