Retrospective review of 71 talar neck fractures from the Campbell Clinic with average 12.7-year follow-up. The study validates Hawkins' classification, quantifies AVN risk by fracture type, and introduces the Type IV fracture and the Canale radiographic view. It also provides the longest published outcome data on conservative AVN management.
Every talar neck fracture you see in the trauma bay should immediately prompt AVN risk stratification by Hawkins type, because the management conversation with the patient is entirely different for a Type I (13% AVN, near-certain good result) versus a Type III (84% AVN, only 48% satisfactory outcomes).
For displaced Type II and III fractures, anatomic reduction is the priority. The reduction threshold is strict: less than 5 mm displacement and less than 5 degrees of malalignment. If closed reduction fails, proceed to ORIF. When you check your post-reduction films, add the Canale view (maximum equinus, 15° pronation, 75° cephalad X-ray tube) — varus malreduction is invisible on a standard AP and is the leading cause of poor outcomes in Type II fractures.
When you diagnose AVN, do not rush to salvage surgery. This paper's 15-year follow-up data shows that none of 23 conservatively managed AVN patients needed an operation. Protect the talus with non-weight-bearing for approximately 8 months; if full non-weight-bearing is not feasible, a patellar tendon-bearing brace is the next best option.
If salvage becomes necessary, match the procedure to the joints involved. Tibiocalcaneal fusion outperforms talectomy alone when both ankle and subtalar joints are affected. Before fusing any one joint, assess both. Fusing the subtalar joint in a patient with coexisting ankle arthritis will transfer stress to the ankle and worsen the result.
