Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.

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.
On average, this disease occurs, according to different authors, in 2.5-7.8% of the world population.
Hallux rigidus is a complex disease and numerous conservative and surgical treatments have been developed and described for its treatment. The doctor is faced with the difficult task of choosing an intervention method, for which it is necessary to pay attention to certain criteria: the degree of arthrosis, the age and level of activity of the patient, and the expectation of the result. Conservative treatment can lead to satisfactory performance in selected patients with grade 0 and grade I arthrosis of the first metatarsophalangeal joint with low functional requirements. In the middle stages of arthrosis, an isolated cheilectomy or osteotomy of the proximal phalanx and metatarsal bone is performed, which, despite their differences, for the most part does not lead to a significant increase in the range of motion in the joint. At the 3rd and 4th degrees of arthrosis, arthrodesis, resection arthroplasty and arthroplasty of the first metatarsophalangeal joint are used.
