Chronic lateral ankle instability is an extremely common disease in the active working population. Unfortunately, the study of this pathology in children and adolescents receives very little attention in the modern literature, although they also suffer from manifestations of ankle instability. We present a clinical example of surgical treatment of a 15-year-old patient suffering from chronic lateral ankle instability. The result of treatment after one year of observation was regarded as excellent. The symptoms of the disease were stopped, the patient has no restrictions in household activities and returned to the level of motor activity that was before the injury.

In the structure of injuries among patients with fractures of the patella, patients of working age prevail, placing high demands on the functional results of surgical treatment and terms of recovery. Given the low incidence of this pathology in the structure of all injuries of the musculoskeletal system, the authors are of the opinion that patients with patella fractures should receive specialized care that meets the requirements for certain types of fractures in trauma hospitals of any level. The described clinical example describes the medium-term results of treating a patient using a patented method of osteosynthesis of the patella that meets both the requirements of patients and the basic principles of osteosynthesis of intra-articular fractures. The data provided is characterized as good, the use of the patented method is regarded as expedient.

Abstract. Patients (n = 66) were divided into 2 groups. In the main group, tendon-muscle plasty was performed in the form of transposition and tenodesis of the tendon of the anterior tibial muscle in the cleft of the navicular bone, and in the control, a combination of this type of tendon-muscle plasty and subtalar arthroeresis. In the period from 2016-2021, the ortho-paediatric department of Clinic of the Samara State Medical University carried out a comprehensive treatment of 66 children with plano-valgus deformity of the feet, which included surgical correction, immobilization of the limb in the postoperative period and rehabilitation treatment for all periods of postoperative observation. Our results indicate the need for an integrated approach in the treatment of flat-valgus deformity of the feet, which includes the formation of an anatomically correct installation of all elements that make up the child's foot and ankle joint, correction of biomechanics and the development of the correct walking skill in the postoperative period.

This article presents a clinical example of treatment of a patient with secondary post-traumatic deformity of the proximal femur due to a solitary bone cyst. The cyst cavity was filled with spongeous bone homograft LYO-57, which served as a substrate for a consistent bone regeneration. The quality of the formed bone made it possible to perform corrective osteotomy of the proximal femur with stable osteosynthesis for the secondary deformity. The results of treatment allow us to recommend this type of homotransplant for the treatment of patients with solitary bone cysts.
