Abstract
Purpose
Intertrochanteric femoral fractures (IFF) are one of the most common traumatic conditions, but there are no established treatment methods for this condition due to implant failure and re-operation rates. The proximal femoral bionic nail (PFBN), which is a new design of the cephalomedullary nail, was developed by our team. The objective of this study was to assess the clinical and radiographic outcomes of PFBN in patients with unstable IFF.
Methods
From October 2020 to August 2021, 12 patients diagnosed with unstable IFF (31-A2, 3) were treated with PFBN at the Third Hospital of Hebei Medical University. We evaluated the clinical therapeutic effects of this treatment by measuring peri-operative indicators and post-operative complications. Clinical outcomes, specific radiographic parameters, and post-operative complications were collected and analyzed within the first post-operative year.
Results
The average age of the patients was 72.4 ± 16.1 years (five males and seven females). The mean operation time was 90.4 ± 16.0 min, whereas the operation time of 31-A2 fractures (83.1 ± 12.2 min) was shorter than that of 31-A3 fractures (105.0 ± 12.9 min) (p < 0.05). The blood loss was 175 ml (range: 50 to 500 ml), and the length of hospitalization was 10.0 ± 1.9 days. The prognosis evaluation was assessed at three, six and 12 months after the operation; for these time points, the Harris hip scores were 69.6 ± 4.1, 77.8 ± 3.8, and 82.6 ± 4.6, respectively, and the Parker-Palmer scores were 5.3 (5.0, 7.0), 6.3 (5.3, 7.0), and 7.8 (7.0, 8.0), respectively.
Conclusion
PFBN has shown advantages in the treatment of unstable IFF (particularly in geriatric patients) and possesses both stability and safety. This innovative method may provide a new option for treating unstable IFFs.
