Analysis reveals significant improvement in foot function through surgical treatment of malunited calcaneal fractures, suggesting effective methods like calcaneal osteotomy and subtalar fusion.
Depending on the severity of residual deformity malunited calcaneal fractures may lead to significant restrictions of daily life and to invalidization of patients. Pathophysiology of malunited calcaneal fracture, diagnostics, classifications and current methods of surgical treatment are discussed in the article. Essential for proper pre-operative planning are weightbearing radiograms (hindfoot alignment view and lateral projection of the ankle and foot), which provide important information of the degree of deformity and the direction of the axial malalignments. Surgical treatment is aimed to pain-free function of the foot, what can be achieved by the restoration of correct height of the calcaneus and restoration of the correct axial alignment. Depending on the severity of the deformity, surgical treatment may include marginal calcaneal osteotomy, subtalar fusion in situ, different modifications of correcting subtalar fusion and/or calcaneal osteotomies. Current treatment modalities provide significant improvement of the functional condition of the foot with acceptable rate of complications.
