Abstract:

BACKGROUND: Dynamic hip screw (DHS) is the gold standard for clinical fixation of intertrochanteric fractures, and achieves certain effect. But proximal femoral nail anti-rotation (PFNA) blade is a new modified proximal femoral fixation system, which is used to solve the deficiencies of previous fixation.
OBJECTIVE: To compare the clinical effect of DHS and PFNA blade for intertrochanteric fractures.
METHODS: Totally 76 patients with intertrochanteric fractures were selected including 36 cases treated with DHS and 40 cases with PFNA. All the patients received operative treatment with common operative route.
RESULTS AND CONCLUSION: Incidence rate of medical complication and deformity rate of hip joint in the PFNA group were lower than those in the DSH group (P < 0.05). The excellent and good rate of the hip function recovery was 78% (28/36) in the DSH group, and which in the PFNA group was 82% (33/40). The results showed that both the two method of DHS and PFNA have good clinic curative effect for the treatment of intertrochanteric fractures, but the PFNA has the advantages of simple operation, less bleeding, and reliable fixation.
