Résumé
Calcaneal fracture-dislocations are rare but potentially disabling injuries that are regularly overlooked at first presentation. To date, only about 50 cases have been reported in the literature. Over a period of 8 years, 10 patients (average age 61.7 years) with acute fracture-dislocations of the calcaneus were treated at 2 level 1 trauma centers. The calcaneocuboid joint was involved in 9 patients. There was a concomitant fracture of the lateral talar process and of the tip of the distal fibula in 7 patients each. Open reduction and internal fixation was performed in 9 of 10 patients via an oblique lateral dislocation approach. One patient underwent primary subtalar fusion. All patients were seen for clinical and radiographic follow-up at an average of 3 years using patient-reported outcome scores. Anatomic fixation was achieved in all patients as judged by postoperative computed tomographic imaging. In the 9 patients treated with internal fixation, the Foot Function Index averaged 12.8, the EuroQol 5D score averaged 0.89 and the visual analog scale score for patient satisfaction averaged 79.3 at final follow-up. Signs of mild subtalar arthritis were seen in 6 patients. No secondary subtalar fusions were needed. When recognized and treated early, prognosis of calcaneal fracture-dislocation was favorable. A dislocation approach starting over the distal fibula, continuing over the sinus tarsi, and extending toward the calcaneocuboid joint allowed for adequate visualization of the subtalar joint and treatment of all components of the injury. Level IV, retrospective case series.

BACKGROUND
BACKGROUND
Calcaneal fracture-dislocations are rare but potentially disabling injuries that are regularly overlooked at first presentation. To date, only about 50 cases have been reported in the literature.
METHODS
METHODS
Over a period of 8 years, 10 patients (average age 61.7 years) with acute fracture-dislocations of the calcaneus were treated at 2 level 1 trauma centers. The calcaneocuboid joint was involved in 9 patients. There was a concomitant fracture of the lateral talar process and of the tip of the distal fibula in 7 patients each. Open reduction and internal fixation was performed in 9 of 10 patients via an oblique lateral dislocation approach. One patient underwent primary subtalar fusion. All patients were seen for clinical and radiographic follow-up at an average of 3 years using patient-reported outcome scores.
RESULTS
RESULTS
Anatomic fixation was achieved in all patients as judged by postoperative computed tomographic imaging. In the 9 patients treated with internal fixation, the Foot Function Index averaged 12.8, the EuroQol 5D score averaged 0.89 and the visual analog scale score for patient satisfaction averaged 79.3 at final follow-up. Signs of mild subtalar arthritis were seen in 6 patients. No secondary subtalar fusions were needed.
CONCLUSION
CONCLUSIONS
When recognized and treated early, prognosis of calcaneal fracture-dislocation was favorable. A dislocation approach starting over the distal fibula, continuing over the sinus tarsi, and extending toward the calcaneocuboid joint allowed for adequate visualization of the subtalar joint and treatment of all components of the injury.
