Abstract

PURPOSE
The aim of this study is to investigate the clinical performance and safety of Zimmer® natural nail cephalomedullary nail (ZNN CM nail) in the treatment of proximal femur fractures.
MATERIALS AND METHODS
The following research was conducted as a prospective, non-comparative, single center outcome study. Upon providing written informed consent, enrolled patients' data were collected and analyzed. Postoperative follow-up visits were scheduled at 6 weeks, 3 months, 6 months, and 1 year. Follow-up evaluation included radiographic assessment, physical examination, and quality of life and adverse events reports.
RESULTS
Thirty-nine patients were available for evaluation at one year postoperative. The patients reported the mean EuroQol-5 Dimension score increased after surgery: from 0.4 points at discharge (n=49) to 0.6 points at 1-year post-surgery (n=39). The mean Harris hip score also increased after surgery: from 56.3 points at discharge (n=49) to 72.1 points at 1 year (n=12). Bone union was seen in 64% (n=16) in 6 months and 95% (n=37) in 1 year.
CONCLUSION
The results of this 1-year follow-up study affirmed the effectiveness and safety of the ZNN CM nail in the treatment of proximal femur fractures.
