[Trabecular metal box for acute acetabular fracture in an elderly patient]

We are currently observing an increase in the incidence of acetabular fractures in elderly patients due to the increase in this population age group. These fractures represent a challenge to the traumatologist because in some cases there is the surgical alternative of combining fixation with total acute hip arthroplasty. In this paper we explore the use of trabecular metal combining the stability provided by a cage with potential bone incorporation, applying the principles of revision surgery to speed-up the healing process without the limitations resulting from the restrictions in the load of the operated limb.

We assessed the clinical and radiological results, with a 2-year follow-up, after total hip arthroplasty for the acute treatment of an acetabular fracture of the anterior column, with involvement of the quadrilateral lamina in an elderly 85 year-old patient.

Important pain relief occurred, with functional improvement and an appropriate range of motion using the Merle d'Aubigné system. Radiologically, the graft areas in the particles surrounding the acetabular component were uniformly integrated. No loosening, screw rupture or implant migration occurred.

This indication using a revision technique based on a trabecular metal reconstruction cage should be considered as an alternative to bear in mind in these patients.
