The Sangeorzan classification of navicular body fractures provides a comprehensive categorisation of navicular body fractures, segmenting them into three distinct types:
Type 1 – Coronal Fracture with No Dislocation: In this classification, Type 1 navicular fractures occur in a coronal pattern, involving a break without any accompanying joint dislocation. While the injury itself can be painful and debilitating, the absence of dislocation suggests a relatively more favorable prognosis. Medical intervention and treatment are essential, but the outcome might be less severe compared to other types.
Type 2 – Dorsolateral to Plantomedial Fracture with Medial Forefoot Displacement: Type 2 fractures present a more complex scenario. Here, the fracture extends from dorsolateral to plantomedial, leading to a displacement of the medial forefoot. This misalignment can cause significant discomfort and hinder mobility. Medical attention is crucial, as proper treatment can play a pivotal role in minimizing the impact of displacement and promoting proper healing.
Type 3 – Comminuted Fracture with Lateral Forefoot Displacement: Among the three types, Type 3 carries the most challenging prognosis. A comminuted fracture involving the navicular body leads to a fragmented pattern, often accompanied by lateral forefoot displacement. This type poses the highest risk of complications, demanding prompt and thorough medical intervention. Specialists may need to devise comprehensive treatment plans to address both the comminution and displacement.
