[Arthrodesis of the hip using a cobra plate. Comments on preliminary reports].

Authors report 50 arthrodesis of the hip joint with AO cobra-plate, and consider that it's a difficult procedure that will be performed by capable surgeons. The complications are infections (26 per cent), inestability after surgery with bend and break of implants occasioned by bad surgery. The most important badness was found by modifying the steps of the precise technique and our opinion is to perform exactly the arthrodesis of the hip joint as the AO group to obtain successful results (88 per cent).
