Clinical results of surgical treatment for femoral neck fractures with the Targon® FN

Abstract

84 cases (male 15 cases, female 69 cases) of intracapsular femoral neck fractures treated with the Targon^® FN (TFN) were available for review. Mean patient age was 74.0 years (range 36-100 years). 55 fractures were undisplaced whereas 29 were displaced. Mean follow-up term was 16.4 months. We surveyed patient mobility before injury and after operation as well as postoperative complications. On a four-stage mobility scale we found 3/55 patients with undisplaced fractures loosing mobility by more than one grade (5.5%), whereas 5/29 (17.2%) displayed this kind of functional decline after displaced fractures. Overall postoperative complication rate was 10.7% (9 cases). These complications included nonunion (1 case), avascular necrosis (7 cases) and peri-implant fracture (1case). Internal fixation with the TFN seems to have an acceptable complication rate in both undisplaced and displaced fractures compared to other recent studies.
