The rate of subtalar arthrodesis based on a computed tomography (CT) scan after open reduction and primary subtalar arthrodesis for acute, displaced, intra-articular calcaneal fractures yielded better outcomes.

A retrospective chart review was performed to identify patients who sustained an acute, displaced, intra-articular calcaneal fracture and underwent open reduction and primary subtalar arthrodesis. 35 patients participated in the study.

All patients were evaluated with CT for arthrodesis of the posterior facet of the subtalar joint, which was quantitated. Other outcome measures included radiographic parameters, the Veterans RAND Item Health Survey, and the Foot and Ankle Ability Measure.

Results:
--The median patient age was 47.8 years (range 21.5–79.5 years). The median patient follow-up was 34.4 months.

--The Sanders classification was as follows: 3% (1/35) type II, 40% (14/35) type III, and 57% (20/35) type IV.

--Based on a CT scan, primary subtalar union occurred in 94.3% of patients.

Finally, for acute, displaced, intra-articular calcaneus fractures, open reduction and primary subtalar arthrodesis has a high rate of union and good pain and function outcomes. Patients with substantial cartilage damage and posterior facet comminution should definitely consider it.
