In Hawkins classification, what characterizes a Type 2 talar neck fracture?

• A. Nondisplaced fracture
• B. Fracture with STJ dislocation/subluxation
• C. Fracture with ankle dislocation/subluxation
• D. Fracture with T-N dislocation/subluxation

Answer: (B)

In Hawkins classification, a Type 2 talar neck fracture is characterized by a fracture accompanied by subluxation or dislocation of the subtalar joint (STJ). This classification scheme helps in understanding the severity of talar neck fractures and the associated complications. When the talar neck is fractured, the extent of associated joint injuries is crucial since it can affect prognosis and treatment strategy. In Type 2, the presence of dislocation or subluxation at the subtalar joint highlights a more severe injury that typically also increases the risk for complications such as avascular necrosis of the talus. The other options do not accurately represent the characteristics of a Type 2 fracture within this classification system. For instance, a nondisplaced fracture would fall under a different classification, and dislocation or subluxation involving the ankle or talonavicular joints are indicative of other types in Hawkins classification. Thus, the defining feature of a Type 2 talar neck fracture is indeed its association with subtalar joint dislocation or subluxation.
