Abstract EN
Objective.
Unstable pertrochanteric fractures are usually treated with internal fixation, and the integrity of the anteromedial cortex is an important factor for stability and healing.
In this study, we described and analyzed the three-dimensional mapping technology and morphological characteristics of pertrochanteric fractures.
Methods.
Fifty-nine pertrochanteric fractures (OTA/AO 2007 types 31A2) were retrospectively reviewed.
Computed tomographic (CT) images for all fractures were superimposed on a standard template.
Medial wall integrity was analyzed, and three-dimensional fracture maps were created.
Results.
Pertrochanteric fractures always have a posterior defect in the medial cortex.
The mean width of the defect, in our study, was 21.5 mm (SD: 6.1 mm, range: 10–40 mm), 56.3% (SD: 13.7%, range: 27.5-100%).
Bone segments that contact by the anteromedial cortex were 16.5 mm (SD: 5.3 mm, range: 0-29 mm).
Conclusion.
The integrity of the anteromedial cortex should be considered during internal fixation of femoral trochanteric fractures.
These morphological characteristics could be used to form postoperative cortical contact and improve stability of the fixation.
Three-dimensional mapping technology can help establish a typical fracture model, thereby improving doctors’ understanding of fracture characteristics.
