Abstract
The influence of threee different fixation devices on late healing complications after femoral neck fractures was studied in a large patient group from three different hospitals. Except for the choice of device, which was unique to each hospital, all other factors having a potential influence on the late outcome, such as sex and age of the patients, initial degree of fracture dislocation and quality of surgical reduction were similar among the three groups. Within a 2-year observation period the incidence of late segmental collapses (14%–19%) was not related to choice of device, but a higher number of non-unions (27%–30%) occurred after adaptive non-rigid methods using screws (von Bahr) or a flanged nail (Rydell) than after a more rigid osteosynthesis (8%, Deyerle). Using such a rigid fixation, the complication rate could be reduced by one-third and the need for revision surgery halved. A device providing stable fixation should be preferred for treatment of femoral neck fractures in the elderly to prevent the healing complications related to insufficient stabilization.
