Objetivo

Estudio prospectivo, controlado, diseñado para determinar el remodelado periprotésico de un vástago femoral anatómico, no cementado y de anclaje metafisario, mediante densitometrías de la masa ósea femoral en los primeros tres años de evolución.

Material y método

En 69 pacientes se efectuó el seguimiento densitométrico de la cadera intervenida y de la contralateral, sana, utilizada como control. Las densitometrías se realizaron en el preoperatorio, a los 12 y 36 meses en ambas caderas, con un estudio adicional de la cadera intervenida a los 6 meses.

Resultados

La densidad mineral ósea mostró, a los 3 años, un incremento en las zonas 2 y 6, de 7,05 y 5,92%. Las zonas 1 y 7 mostraban un descenso de 8,26 y 16,81% por atrofia proximal. Las diferencias en peso, edad y posición del implante no causaron diferencias en el patrón de remodelado. Únicamente el sexo de los pacientes influyó de forma significativa.

Conclusiones

El vástago femoral anatómico consigue un anclaje eficiente a nivel metafisario, con transmisión de cargas que minimizan la pérdida ósea a ese nivel y determinan un estímulo a largo plazo que permite la conservación ósea en zonas más distales.

Aim

To carry out a prospective, controlled study designed to determine the periprosthetic remodeling of an anatomic, non-cemented, femoral stem anchored in the bone metaphysis, using femoral bone mass densitometry studies during the first three years of evolution.

Materials and methods

A densitometric followup was carried out in 69 patients who had one operated hip and a healthy contralateral hip that was used as a control. The densitometries were performed on both hips, preoperatively, at 12 and at 36 months. An additional densitometry of the operated hip was done at 6 months.

Results

At 3 years bone mineral density had increased in zones 2 (7.05%) and 6 (5.92%), and had decreased in zones 1 (8.26%) and 7 (16.81%) due to proximal atrophy. No differences in the remodeling pattern were seen due to differences in weight, age or position of the implant. Only patient gender had a significant influence.

Conclusions

The anatomic femoral stem achieves efficient fixation in the bone metaphysis, and a load transmission pattern that minimizes bone loss at this level and causes a long-term stimulus that allows bone preservation in more distal areas.
