Background:
Calcaneal fractures have complex morphology, which brings great challenges to clinical treatment. The primary fracture lines could help us simplify the fracture. Fracture mapping technology can help surgeons understand the fracture morphology more intuitively. This study aims to develop a further understanding of calcaneal fractures by delineating the primary fracture lines through the fracture mapping technology.
Methods:
Ninety cases of intra-articular calcaneal fractures were reviewed between March 2016 and January 2019 at a level 1 trauma centre. The CT data of these cases were reconstructed and reduced using software. We superimposed the primary fracture lines on a standard model and created the distribution and heat map of the intra-articular calcaneal fractures. SPSS 18.0 was used to count the differences between the different groups.
Results:
The primary fracture lines concentrated at the Gissane angle and the posterior articular surface, which could be summarized in two ring structures. There were 43 cases of fracture involving calcaneocuboid joint, including 32 cases of joint-depression fracture and 11 cases of tongue-type fracture. The area ratio of lateral fragment of simple tongue-type fracture is larger than joint-depression fracture.
Conclusion:
The primary fracture lines of calcaneus were distributed in two rings on the surface of calcaneus. Based on the distribution of primary fracture rings, we integrated the classification of calcaneal fracture and proposed some treatment recommendations.
