Abstract Background: Revision total hip arthroplasty is frequently accompanied by bone loss. The purpose of this study is to evaluate mid- to long-term results of revision total hip arthroplasty for massive femoral bone loss using cementless modular, fluted, tapered stems.Methods: During the period of 2007 to 2015 at a single hospital, 34 hips (33 patients) underwent primary revision surgery with cementless modular, fluted, tapered stems due to massive bone loss, and patients with prosthetic joint infection (PJI) or tumours were excluded. The hips were revised with the LINK MP (Waldemar Link, Hamburg, Germany) prosthesis. Bone loss was categorized by the Paprosky classification for prosthesis loosening and Vancouver classification for peri-prosthetic fracture. All revision bearing surfaces were ceramic-on-ceramic (CoC). Clinical outcomes, radiographic outcomes and survivorship were evaluated.Results: The mean follow-up was 9.1±2.5 years (range, 5-13 years). The Harris hip score was 43.6±11.5 preoperatively and maintained at 86.5±6.6 at the time of latest follow-up (p<0. 05). The X-ray showed bone ingrowth fixation in 30 hips (88%), fibrous stable fixation in 3 hips (9%) and instability in 1 hip (3%). The average stem subsidence was 3.9±2.2 mm (range, 1 to 10 mm). The survivorship of prostheses with re-revision for any reason was 95% (95% CI, 12.0 to 13.0) at the 10-year follow-up. Three (9%) re-revisions were needed, including 1 for aseptic loosening, 1 for dislocation and 1 for infection.Conclusions: The mid- to long-term results of revision total hip arthroplasty with the cementless modular, fluted, tapered stem (LINK MP stem) are encouraging for massive femoral bone loss.

<p><strong>Introducción: </strong>El objetivo de este estudio retrospectivo fue observar el comportamiento de un tallo modular de fijación proximal y anclaje distal en revisiones de cadera con defectos femorales II y IIIA (Praposky), evaluando la estabilidad protésica y articular, la restauración del off-set y la discrepancia de longitud.</p><p><strong>Materiales: </strong>Analizamos 22 RRTC de los cuales 12 (56,5%) fueron mujeres y 10 varones con un promedio de edad de 62,38 años. El seguimiento promedio fue de 62 meses. El tallo femoral utilizado fue el S-ROM<strong> ®</strong> (Depuy – J&amp;J). Los defectos óseos femorales fueron 15 tipo II y 7 IIIA de Praposky. Para la evaluación clínica se utilizó el Score de cadera de Harris (HHS). Radiológicamente se analizó el comportamiento del tallo, su integración, la discrepancia de longitud y el off-set femoral, considerándose como correcto una diferencia menor a 5mm.</p><p><strong>Resultados: </strong>el offset fue restaurado en 16 (72,3%) casos y la longitud de miembros se restauró en 15 (68,2%). Hubo un solo hundimiento del tallo, y de acuerdo con Engh se observaron 17 (77,27%) uniones óseas. Hubieron 7 (31,8%) complicaciones, 2 luxaciones que requirieron revisión, 4 fracturas intra-operatorias y una paresia de CPE.</p><p> </p><p><strong>Conclusión</strong> este tallo impresiona ser una alternativa valida para resolver un problema complejo. Por su versatilidad, permite resolver mecánicamente el defecto óseo, devuelve la longitud al miembro y el off set a la articulación, presentando un índice de complicaciones aceptables.</p><p> </p>
