Περίληψη:
Between January 1998 and December 1998, 82 consecutive patients (86
hips) underwent total hip arthroplasty using a trabecular metal
monoblock acetabular component. All patients had a clinical and
radiological follow-up evaluation at six, 12 and 24 weeks, 12 months,
and then annually thereafter. On the initial post-operative radiograph
25 hips had a gap between the outer surface of the component and the
acetabular host bed which from 1 to 5 mm. All patients were followed up
clinically and radiologically for a mean of 7.3 years (7 to 7.5). The 25
hips with the 1 to 5 mm gaps were studied for component at two years
using the Einzel-Bild-Roentgen-Analyse (EBRA) digital measurement At 24
weeks all the post-operative gaps were filled with bone and no
acetabular had migrated. The radiographic outcome of all 86 components
showed no radiolucent lines and no evidence of lysis. No acetabular
implant was revised. There were no dislocations or other complications.
The bridging of the interface gaps (up to 5 mm) by the trabecular metal
monoblock acetabular component indicates the strong osteoconductive, and
possibly osteoinductive, properties of trabecular metal.
