Table 2 Distribution of clinical prognoses of the three fixation groups after at least 2 years of follow-up

From: Enhanced interfragmentary stability and improved clinical prognosis with use of the off-axis screw technique to treat vertical femoral neck fractures in nongeriatric patients

Outcome, n (%) G-TRI (n = 107) G-ALP (n = 65) G-DHS (n = 32) P value*
Fixation failure 42 (39.3%) 12 (18.5%) 12 (37.5%) 0.015*
Nonunion 13 (12.1%) 2 (3.1%) 4 (12.5%) 0.111

  1. *p < 0.05
  2. aCut-out is defined as protrusion of the screw out of the femoral head
  3. bHHS was significantly different between G-ALP and G-ITR (p = 0.037)
