Surgical Correction of Dysplastic Coxarthrosis and Endoprosthesis Replacement by TiNi-based Implants

Dysplastic coxarthrosis is predominating among children orthopedic cases and its surgical correction continues to be an urgent issue. Despite the application of advanced therapies and medical treatment, such patients constitute a significant percentage of the total patient number, i. e. from 19 to 35%. In this article a detailed literature review of surgical correction methods for missing acetabular roof by applying different implants has been described. The authors have proposed applying titanium nickelide materials in surgical correction method, as such materials possess the following properties: high corrosion stability, full compatibility with the body tissues, as well as, high porosity to provide radial border structure regeneration of the acetabular roof, which in its turn, improves the support ability of extermity. In the event of coxarthrosis progression iliac segment is reserved for the replacement

Surgical Correction of Child Pectus Excavatum by TiNi-based Materials

This article describes the serious and urgent issue of surgical treatment of congenital child pectus excavatum and the approaches in the surgical correction of this children pathology. The authors propose an original surgical treatment method in applying TiNi-based materials possessing shape memory in OP treatment of pectus excavatum. Plain integral TiNi-based plasty creates supplemental correction force due to the material isoelastic properties, providing stable fixation of corrected chest section throughout the immobilization period

Surgical Correction of Child Planovalgus Deformity by Porous TiNi-based Implants

The question of child degenerative-dystrophic diseases is predominate in orthopedic pathology, where the problem of its treatment is very acute. Excluding the modern treatment methods, the number of children suffering planovalgus deformity is comparably more to total orthopedic patients. This article describes a surgical treatment method of child planovalgus deformity by applying porous biocomposite materials from TiNi alloy. The method involves inserting porous frustoconical composite TiNi implant into subtalar joint, which, in its turn, could correct the deformation and shape the arch of foot eliminating planovalgus deformity
