We have been treating femoral neck fractures using cannulated cancellous screws, in accordance with individual cases. The clinical results of 43 patients treated between 2003 and 2009 were reviewed retrospectively, with the aim of clarifying any problems with our therapeutic algorithm.
The mean age of the patients at surgery was 70.0 (range 27-96) years ; 31 patients had a non-displaced fracture and 12 had a displaced fracture. Patients aged less than 65 years (group U) mostly had displaced fractures, whereas patients aged 65 years or more (group O) mostly had non-displaced fractures. All patients were followed radiographically for a mean period of 19.0 (range 6-58) months.
There were no cases of non-union in the non-displaced fracture group, and 4 cases of non-union in the displaced fracture group.
The patients in whom operative reduction was good had a 94.9% union rate, but those in whom reduction was poor had a 50.0% union rate.
Although we were relatively satisfied with these results, we conclude that the type of fracture and reduction during surgery need to be given sufficient consideration.
