Abstract
Navicular fractures are rare and pose significant surgical challenges. This study aimed to define the location and frequency of fracture lines using both two-dimensional (2D) and three-dimensional (3D) computed tomography (CT) mapping. We hypothesized that fracture mapping could reveal constant fragments, as well as patterns of impaction and comminution, to help optimize surgical management.
A retrospective analysis of CT scans from 44 patients was performed. Fractures were classified according to the Sangeorzan system. Three-dimensional reconstructions were used to identify key fracture patterns, zones of impaction, and the presence of a constant plantar fragment, based on a 360-degree quadrant mapping approach.
Type 1 fractures (n = 8) were simple transverse fractures with no reproducible pattern. Type 2 fractures (n = 10) followed an oblique dorsolateral-to-plantar-medial trajectory, with 43% showing impaction in the lateral quadrant. Type 3 fractures (n = 26) were associated with comminution in 96% of cases and impaction in 81%, with fracture lines converging at the talonavicular joint. A constant plantar fragment was identified in 56% of Type 2 and 73% of Type 3 fractures.
3D navicular fracture mapping may improve understanding of fracture morphology and injury mechanisms. By identifying consistent fracture features, this technique may assist in preoperative planning and inform reduction and fixation strategies.
