Association of pre-treatment radiographic characteristics of calcaneal fractures on patient-reported outcomes

Purposes Calcaneal fractures are known to influence patients’ quality of life negatively. The type of calcaneal fracture might have a relation with the patient outcome. To inform patients in an early stage on how their calcaneal fracture may affect their lives, knowledge of the fracture characteristics is necessary. This study evaluates the association of type of calcaneal fracture, measurement of conventional radiograph angles, and the Sanders classification with patient-reported outcomes. Material and methods This is a retrospective study based on a prospective trauma database including all patients aged 16 years or older with a calcaneal fracture admitted in one of the participating trauma level I or II hospitals. Patients, trauma, and fracture characteristics were collected. The conventional radiographs were evaluated in which type of fracture, and Böhler’s, Gissane’s, and calcaneal compression angles were determined. Also, the CT images were classified according to Sanders. In addition, displaced intra-articular calcaneal fractures were separately analyzed. A questionnaire was sent to the included patients that consisted of the EQ-6D, patient-specific characteristics, satisfaction with foot appearance and wearable shoe range, complications, and capability to work. Results A total of 396 patients with 442 calcaneal fractures were eligible for follow-up. Two hundred fifteen patients with 246 calcaneal fractures participated. Patients with a calcaneal fracture into the talar surface reported a worse quality of life ( p = 0.010), were less satisfied with their feet ( p
