Displacement in femoral neck fractures: A numerical analysis of 200 fractures

Abstract

We measured the proximal-distal and anterior-posterior displacement of the femoral head in 200 femoral neck fractures. The numerical data were compared with the Garden classification. The average displacement of the Stages I and II fractures were almost equal. Moreover, the displacement of the Stage III fractures did not differ from the displacement of the Stage IV fractures. The Garden Stages I and II fractures displayed a more posterior position of the femoral head than did the normal hips. The femoral heads of Stages III and IV were situated more posterodistally than those of the Stages I and II fractures. Classification of femoral neck fractures into two groups without (Stages I and II) and with (Stages III and IV) proximal displacement is probably sufficient for clinical use.

Outcome of undisplaced and moderately displaced femoral neck fractures

“…This study provides evidence of the usefulness of classifying the fractures as being undisplaced or moderately displaced. Previous studies have shown that the Garden classification system is unreliable (Eliasson et al 1988, Frandsen et al 1988, Thomsen et al 1996, Bjorgul and Reikeras 2002, but the interobserver reliability may be acceptable when distinguishing between displaced and undisplaced fractures (Eliasson et al 1988, Frandsen et al 1988, Thomsen et al 1996, Bjorgul and Reikeras 2002. The significant difference in healing complications in our study indicates that moderately displaced fractures behave differently from undisplaced fractures.…”

Redisplacement of nailed femoral neck fractures: 4-year follow-up of 110 cases

“…We have previously measured the preoperative displacement of femoral neck fractures in the proximaldistal and anteroposterior directions (Eliasson et al 1988). Meaningful differences were found only if the Garden (1961) classification was condensed to two groups; one consisting of Stages I and TI (undisplaced fractures) and the other of Stages III and IV (displaced fractures).…”

Trochanteric advancement for premature arrest of the femoral-head growth plate: 6-year review of 30 hips

“…Preoperatively, passive range of motion and Trendelenburg's sign were recorded, and the articulo-trochanteric distance on frontal radiographs was measured according to Edgren (Edgren 1965, Gage and Cary 1980, Eliasson et al 1988). …”
