Background: Segmental femur fractures often pose management challenges regarding the optimal fixation choice and sequence of surgical events.
Methods: Retrospective review of clinical records and radiographic data of adult patients with segmental femur fractures treated by a conceptual radiographic cover-up test to determine the ideal fixation method between January 2019 and December 2020.
Results: Forty patients with 84 individual fractures underwent fracture fixation. The most consistent fracture combinations were intertrochanter-diaphysis (AO31A-AO32) fractures (25%, n = 10) and femur neck-diaphysis (AO31B-AO32) fractures (20%, n = 8). Compared to evidence-based fracture management, the gold standard treatment was used for the fixation of 78 fractures (93%). One patient required revision for fixation failure of a diaphyseal fracture, and two fractures, both open diaphysis injuries, developed fracture-related infections.
Conclusion: Anatomical alignment and high union rates are possible for segmental femur fractures treated by evidence-based fracture fixation principles. A conceptual radiographic cover-up test assists in matching the best possible implant for each fracture.
