Vástagos monobloque de recubrimiento completo en cirugía de revisión femoral. Resultados a largo plazo de 80 casos.

Bone stock lost and anatomical changes in the proximal femur make femoral revision surgery a complex procedure where the implant chooses will be essential. With the aim of evaluating the clinical and radiological results of the fully coated monoblock stems, we retrospectively studied 80 consecutive cases of femoral revision surgery operated by our hip team. The mean follow-up was 8.6 years. The average score on the Harris Hip Score was 81,2 points. We achieved better results in patients with less bone defects (Paprosky I, II and IIIA) in contrast to those with Paprosky type IIIB defects (p=0.005), in patients with a single previous surgery (p=0.031), in patients under 65 years (p=0.009) and in those who did not suffer complications (p=0.024). The survival rate was 96.1% at 10 years if we consider as failure the removal of the stem due to aseptic loosening and 89.9% if we consider revision of the stem as a failure due to any cause. After the results obtained, we think that fully coated stems provide a solid and stable fixation in femoral revision surgery. However, worst results obtained in patients with bigger bone defects make other options to be considered
