With the numbers studied, the timing of reduction was not related to the development of osteonecrosis. Forty-six fractures were treated with urgent open reduction and internal fixation (ORIF) at a mean of 10.1 hours, primarily for open fractures or irreducible dislocations. Osteonecrosis occurred after 30% of open fractures versus 21% of closed fractures (p = 0.55). Osteonecrosis never occurred in fractures without subtalar dislocation (Hawkins type I and IIA), but 25% of Hawkins type-IIB patterns developed osteonecrosis (p = 0.03), and 41% of Hawkins type-III fractures developed osteonecrosis (p = 0.004). After a mean of thirty months of follow-up, sixteen of sixty-five fractures developed osteonecrosis, but 44% of them revascularized without collapse. One deep infection, two nonunions, and two malunions occurred. Open fractures occurred in twenty-four patients (30%).

The fractures included two Hawkins type-I, forty-four type-II (twenty-one type-IIA and twenty-three type-IIB), thirty-two type-III, and three type-IV fractures.

The cases of eighty patients with eighty-one talar neck and/or body fractures who had a mean age of 36.7 years were reviewed. We investigated the possibility of dividing the Hawkins type-II classification into subluxated (type-IIA) and dislocated (type-IIB) subtalar joint subtypes. We hypothesized that delay of definitive fixation would not increase the rate of osteonecrosis, but that the amount of initial fracture displacement, including subtalar and/or tibiotalar dislocations, would be predictive. Osteonecrosis and posttraumatic arthritis are common after talar neck fracture.
