Abstract

Considerable controversy surrounds the management of talar neck fractures regarding the rate of post-traumatic arthrosis, secondary procedures, avascular necrosis, and the effect of the interval to surgery on these variables. A data search using PubMed was performed with the keywords "talus" and "fracture." The search found 1280 studies. Ultimately, 21 reports involving 943 talar neck fractures were analyzed. Data concerning open fractures, the interval to surgery and its relationship to the incidence of avascular necrosis, and the rates of malunion and nonunion, post-traumatic arthrosis, secondary salvage procedures, and functional outcomes were collected and analyzed. The variables examined were not uniformly reported in all studies. The overall rate of avascular necrosis was 33%, with no demonstrated relationship between the interval to surgery and the rate of avascular necrosis. Malunion occurred approximately 17% of the time, with nonunion occurring approximately 5% of the time. Post-traumatic arthrosis occurred in 68% of patients, although secondary salvage procedures were only performed in 19% of patients. Functional outcomes were difficult to assess, given the variability of reported outcomes and unvalidated measures. The optimal management of talar neck fractures has yet to be determined. Although the present review has improved understanding of these difficult fractures, additional studies that use validated outcomes measures are warranted to determine the effect of delayed surgery on final outcomes and optimal treatment methods.
