CURRENT ISSUES IN SURGICAL TREATMENT OF HINDFOOT DEFORMITIES

Abstract

Abstract. Introduction. The review analyzes and summarizes the results of studying the surgical treatment of traumatic and non-traumatic hindfoot deformities with subtalar joint osteoarthritis. Relevance of this issue is supported by highly frequent unsatisfactory results achieved in primary care, which often lead to post-traumatic subtalar arthrosis, high percentage of the disablement of mostly working-age patients, and economic costs associated with their further treatment and rehabilitation. Subtalar arthrodesis, in combination with bone grafting augmentation with auto-, allo- or xenograft and internal fixation, is the most common surgical technique for patients of this category. Aim. To study the advantages and disadvantages of the known surgical techniques used in treatment of posttraumatic hindfoot deformities. Materials and Methods. To perform the literature analysis, we used international databases, such as Web of Science, Scopus, and PubMed, as well as the domestic library system, eLibrary. Results and Discussion. Despite good surgical treatment outcomes presented in the publications, some failures were registered, such as insufficient deformity correction, arthrodesis nonunion due to the bone graft migration, bone graft osteolysis, metal structure instability, and infectious complications. According to the authors, the key reason for some unsatisfactory results in non-infectious cases was the lack of preoperative planning, including accurate calculations of the necessary hindfoot deformity correction and of the optimal extent of bone grafting.
