Modified Exeter technique in revision hip surgery: does distal fixation of the stem affect allograft transformation?

Promising results have made the Exeter technique a valuable alternative in hip replacement revision. However, even with this technique, subsidence remains a difficult problem because it may lead to additional revision if it is not mild and self-limited. We propose a technical modification that achieves primary stability by cementing the distal portion of the stem directly to the host bone. We conducted a prospective study on 45 hips. After an average of 46 (range, 18-72) months of follow-up monitoring, no hips required or underwent revision for aseptic loosening of the prosthesis. Four stems subsided
