Introduction. Trochanteric fractures are frequent and generally associated with bone fragility. There is still debate on the best fixation device to treat stable or rather stable trochanteric fractures: we report our clinical and radiological results of fixation with Proximal Femoral
Nail “antirotation” (PFNa) in a population of patients compared to a control group treated by Sliding Hip Screw (SHS).
Materials and methods. A prospective study was conducted in 71 consecutive patients treated by PFNa (group A), and 69 by a SHS (group B), with a mean age of 81.6 and 83.4 years respectively. Short Form 12 was administered to check postoperative results, and the following parameters were evaluated: range of motion, evaluation of pain, gait ability, X-rays, and Tip Apex Distance Index.
Results. A minimum follow-up was conducted in 128 patients: 66 subjects belonging to the PFNa group and 62 to the DHS group. All patients in the group A were able to reach partial or full weight-bearing on the operated leg before leaving the hospital. Forty-four patients (63.8%) of the group B were able to walk with partial weight-bearing before discharge.
We recorded 17 complications with a final overall percentage of 17.2% on the overall study population with one single case of failure in both the two groups.
Discussion. A statistical significance (p<0.01) of superiority for PFNa was demonstrated regarding surgical time, amplioscope time, intraoperative blood loss, hospital stay, recovery of weight-bearing before discharge.
Less significant results (p<0.05) were found for walking ability at the three-months follow-up and patients’ satisfaction 6 months after surgery.
Conclusions. PFNa may be considered an useful choice for the treatment of stable or rather stable trochanteric fractures as well as DHS. The light superiority of PFNa may be principally related to its mechanical advantages.
