Revising short-stem THA with either a new short stem or a primary stems: A feasible and durable strategy - 10/03/26
Abstract |
Background |
Short-stem total hip arthroplasty (THA) has gained popularity due to its bone-preserving design, reduced stress shielding, and facilitation of future revisions. However, concerns persist regarding a higher incidence of complications especially during the learning curve. The feasibility of revising Fitmore short stems using either a new short or a standard primary stem, rather than dedicated revision implants, remains debated.
Methods |
We retrospectively reviewed 44 consecutive revisions following primary implantation of a Fitmore® metaphyseal short stem. Revision femoral components were classified as short, primary, or revision stems. Indications for revision, stem choice, and outcomes were analyzed.
Results |
Revision was performed using a short stem in 11 cases, a standard primary stem in 26 cases, and a revision stem in 7 cases. Mean follow-up was 69 months. The mean Harris Hip Score was 82.3 ± 8.4. Two patients (4.5%) required re-revision, one due to traumatic periprosthetic fracture and the other for hematogenous infection.
Conclusion |
Revision of failed short-stem THA using new short stem or standard primary stems is feasible in the vast majority of cases, with excellent mid-to long-term outcomes and a low re-revision rate. These findings challenge the notion that short stem revisions inherently require complex revision implants.
Level of evidence |
IV; Retrospective consecutive case series.
