We have studied the feasibility of isolated endo-medullar extraction of the stem. 19 patients (6 infections, 6 neck fractures, 3 stems with risk of fracture, 3 head fractures, and 1 recurrent dislocation) were subjected to the removal of a stable and bone integrated implant at a mean of 4.5 years after surgery. The 19 cases represent the entire population of Aura cementless integrated stem requiring revision during the period of 2003 through 2011, excluding periprosthetic bone fracture cases. The technique consisted of a careful release of the metaphyseal part of the implant with thin osteotomes, followed by the use of a highly efficient extractor. The re-implanted procedure always utilised standard stems : 17 cementless stems full HA coated (13 had the same size as the removed implant, 4 cases had larger sizes) and two received cemented stems. The 19 stems were extracted by simple endo-medullary approach, without the need for additional action. Several complications were encountered, 1 intraoperative diaphyseal fracture, requiring a wiring, 1 fracture of the lesser trochanter at 15 days post-surgery, requiring a revision and 2 postoperative dislocations. Except for the early revision due to fracture, no other stem was revised. There was no recurrence of infection and the functional results were satisfactory (PMA 15-18). 3 patients showed metaphyseal lucent lines on X-Ray leading us to advise the use of a standard stem with larger size after distal reaming, combined with preventive circulate of the calcar. The use of dedicated instrumentation allows successful extraction of full HA coated short stem by endomedullary approach.
