Boneloc versus Simplex Cement for Fixation of Femoral Components. An Interim Report of a Prospective Randomized Study of THRs with a 2,5 Year Mean Follow-Up Time
A prospective randomized study of femoral stem fixation comparing Boneloc and Simplex cements was carried out. A collarless double-tapered femoral component was used in all cases. The material consisted of 94 patients representing 97 THRs (3 bilateral cases). Their mean age was 76 years (range 58-88). Clinico-radiographic follow-ups were carried out after 3 months, 12 months and 2 to 3 years. The mean follow up time was 2.5 years.
Clinically there was no difference between the groups. Radiolucencies at the bone-cement interface and metal-cement interface, cement cracks, and subsidence of the femoral component were compared. No significant differences could be proven between the fixation patterns of the bone cements during this short-term follow-up.
