Abstract
We performed transesophageal echocardiography on 88 patients treated with cementless or hybrid total hip arthroplasty (THA). We observed a significantly higher frequency of severe embolic events among patients without cup holes during insertion of press-fit cups (46.0%) than in patients with holes (15.6%) (P<.005). During stem insertion, severe embolic events occurred in 61.5% of hybrid operations and 5.9% of cementless operations. PaO2, systolic blood pressure, and arterial oxygen saturation decreased significantly in severe embolic events (P<.05). The results indicate that embolic events may occur during THA whether or not cement is used. Based on these findings, we make several recommendations for technique modifications during insertion of both femoral and acetabular components in THA. Copyright 2003, Elsevier Science (USA).
