Rougher stem surface finish may contribute to high levels of osteolysis and stem failure
The addition of a rougher surface finish to a modular stem may contribute to high levels of osteolysis and stem failure, according to study results. Read more

Abstract

We prospectively followed 112 hips, undergoing THA with a Spectron EF stem. At mean follow-up of 11.2years, 21 patients had died. We obtained radiological follow-up in 99% and clinical follow-up in 100% of the surviving 91 hips. Fifty-four percent demonstrated osteolysis in at least one Gruen zone. Twenty-two hips required revision for all causes, with a further five stems radiologically loose. With endpoint being stem revision for aseptic loosening or radiological failure, survivorship at 11years was 0.783. We believe the addition of a rougher surface finish has contributed to the high levels of osteolysis and stem failure seen with the Spectron EF.





Analizó la evolución de 112 caderas, sometidos a la ATC con un Spectron EF tallo. Enmedio de seguimiento de 11,2 años, 21 pacientes habían muerto. Obtuvimosseguimiento radiológico en el 99% y el seguimiento clínico en el 100% de los que sobreviven 91 caderas. Cincuenta y cuatro por ciento demostró osteolisis en al menos una zona de Gruen. Veintidós caderas requeridos revisión por todas las causas, conotros cinco tallos radiológicamente suelto. Con punto final siendo revisión tallo por aflojamiento aséptico o fracaso radiológico, la supervivencia a 11 años era de 0,783.Creemos que la adición de un acabado de superficie más rugosa ha contribuido a los altos niveles de osteolisis y el vástago insuficiencia visto con el Spectron EF.
