Randomized Controlled Trial Comparative Study Clinical Trial
[Reduction of severe cardiac complications during implantation of cemented total hip endoprostheses in femoral neck fractures].
Intraoperative circulatory and pulmonary problems occuring during the repair of femoral neck fractures with cemented hip arthroplasty are a common problem, that cannot be ultimately explained. As a possible reason for this problem is air embolism during the polymerisation of the methylmethacrylat discussed. We started a prospective randomised clinical examination with 72 patients to prove the efficiency of palacos mixed in vacuum, with respect to the reduction of severe cardiovascular complication during endoprosthetic repair of femoral neck fractures. ⋯ Mortality in the control group amounted to 13.8% in the vacuum group to 2.8%. Through the use of methylmethacrylate mixed in vacuum for surgical repair of femoral neck fractures with cemented hip arthroplasty, the incidence of severe cardiac complications could be reduced significantly. Patients with increased pulmonal arterial pressure have the highest risk for cardiac complications.
