Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To study the biomechanical and anatomical characteristics in patients treated surgically after traumatic calcaneal fracture, and compare these data to healthy subjects, patients after arthrodesis of the subtalar and talar joint. - Is there a relation between the postoperative functional subtalar axis and the clinical functional outcome? - Is there a relation between the functional subtalar axis and the anatomical subtalar axis? | — |
Secondary
| Measure | Time frame |
|---|---|
| To investigate whether the changes in biomechanical and anatomical characteristics determines the post-operative outcome and patient satisfaction. Research questions: - What are the changes in biomechanics after surgery for calcaneal fractures if compared to healthy persons? - What are the changes in biomechanics after calcaneus surgery if compared to patients after arthrodesis of the subtalar joint? - What are the changes in biomechanics after calcaneus surgery if compared to patients after arthrodesis of the talar joint? - Does patient satisfaction after operative treatment correlate with changes in biomechanics? - Have the changes in biomechanics and difference in treatment an effect in the patient satisfaction? | — |
