The current study was conducted to compare the therapeutic effects of proximal femoral nail antirotation (PFNA-II) and artificial total hip arthroplasty (THA) on elderly Chinese patients with unstable intertrochanteric femoral fracture combined with severe osteoporosis. There were 60
people in each group. The duration of surgery, blood loss, and weight-bearing period when standing on the floor were compared between the two groups (P > 0.05). Harries function scores of both groups increased over time. Scores of THA group were significantly higher than those of
PFNA-II group during six- and twelve-months follow-up visit (P < 0.05). In addition, excellent and good rates of hip joint function in THA group were higher than those of PFNA-II group during twelve-month follow-up visit (P < 0.05). The occurrence rates of follow-up complications
in both groups showed no statistical significance (P > 0.05). Thus, both PFNA-II and THA have good effects on Chinese elderly patients with unstable intertrochanteric femoral fracture combined with severe osteoporosis.
