Background:
In this study kinematic parameters, radiographic findings and PROM in pilon fractures after operative treatment were compared with healthy subjects.
Methods:
16 patients treated with osteosynthesis after pilon fracture underwent kinematic analysis with the OFM. Fractures were evaluated for post-operative step-off and gap on CT-scans and PROM were collected. Results were compared to 10 healthy persons.
Results:
Range of motion (ROM) crural was lower in the flexion/extension for pilon fractures (10.03 vs. 13.15, p = 0.017). The ROM in the inversion/eversion was low, but ROM in the abduction/adduction was higher. Correlations were found between flexion/extension and AO-classification (r = -0.357 p < 0.05), PROM score of the AOFAS (r = 0.445 p < 0.01), post-operative gap and step-off in the tibia plafond.
Conclusion:
Pilon fractures showed decreased ROM between the hindfoot and tibia in the sagittal and transverse plane, but increased ROM in the frontal plane during push-off phase as compensatory kinetics. ROM showed significant correlations with PROM and intra-articular step-off and gap in the tibia plafond.
