Aims: A study was undertaken using foot pressure analysis, to assess the biomechanical outcomes following calcaneal fractures using the HR Mat and to assess their correlation with function.

Methods: Twenty four individuals who had been treated for unilateral, intra-articular comminuted calcaneal fractures performed 4 walking trials. 14 patients had operative treatment and 10 were treated conservatively.

Results: There was significant restriction in subtalar and ankle movements on the affected side in both groups. Peak pressures in the midfoot and fifth metatarsal head were significantly higher in the injured foot compared to the normal side. Peak values of forces transmitted by the fractured foot were significantly lower (ANOVA < 0.001). Hindfoot movements, foot pressure and force measurements did not correlate with the AOFAS and Bristol scores.

Conclusions: Calcaneal fractures cause significant alteration of loading in the foot. Altered loading patterns do not appear to have an influence on the functional outcome.
