Experiences with the BiCONTACT revision stems with distal interlocking.
The first consecutive 68 revision total hip arthroplasties of a cementless distal interlocking femoral stem (BiCONTACT; Aesculap AG, Tuttlingen, Germany) are included in this study. Average follow-up time was 40 months (range, 36-49 months). At follow-up evaluation, one patient had died, and one could not be located. The average Harris hip score improved from 60 points to 88 points. All cases showed radiographic evidence of a bone ingrown prosthesis, and no subsidence was seen. No osteolysis and no radiologic loosening were noted. No repeat revision was needed during the follow-up period. The results of the distal interlocking femoral stems (BiCONTACT) in cementless revision total hip arthroplasty were satisfactory. These findings suggest that a diaphyseal fixation of the revision femoral stem with distal interlocking screws can provide primary axial and rotational stability of the prosthesis in revision surgery.
