Summary

Relevance The first metatarsophalangeal joint (MPJ) has an important function in the
 biomechanics of human gait, especially in the toe and thrust phases, as the full range of
 motion at this joint provides the body with smooth horizontal acceleration. The flattening of
 the arches of the foot and, as a result, the overload of its anterior section occupy a
 leading place in the etiology of deforming osteoarthritis (Hallux rigidus). Hallux rigidus is
 a disease associated with degenerative changes in the articular cartilage of the first
 metatarsophalangeal joint. The relevance of the treatment of arthrosis of the first
 metatarsophalangeal joint is determined by the high incidence and functional significance of
 the joint.
 
 At the 3rd and 4th degrees of arthrosis, arthrodesis, resection arthroplasty and arthroplasty
 of the first metatarsophalangeal joint are used.
 
 To date, the most optimal methods of surgical treatment of severe arthrosis of the first
 metatarsophalangeal joint are arthroplasty and arthrodesis of the joint. These operations are
 preferred because they achieve good clinical and radiological results. Long-term follow-up
 studies are needed to confirm the current findings.
 
 Uncoupled endoprostheses are characterized by satisfactory mobility, the ability to withstand
 high loads, and ligament structures are preserved during their implantation. Of the existing
 types of non-bonded endoprostheses, zirconium ceramics has a number of advantages, such as:
 good ingrowth ability, no wear, no rejection reactions. The main advantages of this type of
 surgical treatment are: rapid pain relief, improved function and stability, individual
 adaptation of prostheses. Endoprosthetics is recommended for patients of working age with
 high functional demands.
 
 Thus, the development and implementation of new design solutions in clinical practice is
 relevant and promising.
 
 task in the surgical treatment of patients with deforming osteoarthritis of the first
 metatarsophalangeal joint.
 
 Purpose of the study:
 
 To develop and introduce into clinical practice a new method of surgical treatment of
 patients with deforming osteoarthrosis of the first metatarsophalangeal joint using an
 anatomically adapted endoprosthesis.
