Aim - to reveal the dynamics of somatosensor disorders in patients with coxarthrosis after primary hip joint prosthesis. Materials and methods. 33 patients, average age - 54 ±-7 years, who undergone primary hip joint endoprosthesis were examined. 15 persons without coxarthrosis were enrolled in first group. Our own technique was used for proprioceptive activity determination; “Trust-M” complex for diagnosis, treatment and rehabilitation of patients with locomotive pathology was used for precise estimation of motion amplitude in hip joint and for the obtained data registration. It allowed to register angle magnitude in joints simultaneously in three planes. The examination was conducted before the operation and also in three, six and twelve months after arthroplasty.Results. The increase of proprioceptive insufficiency in 3 months after operation was detected in all patients with coxarthrosis in spite of its etiology and manifestation. Disorders in avascular whirlbone necrosis and in posttraumatic coxarthrosis were more significant than in idiopathic and dysplastic joint injury. In six months the deficiency of proprioceptive insufficiency had no distinctions from its level before the operation in patients with dysplastic and idiopathic coxarthrosis but in patients with posttraumatic coxarthrosis and whirlbone necrosis the distinctions were kept. In one year after the operation in all groups there were no distinctions in comparison with preoperation results. In the comparison of the parameters which were obtained six and twelve months after the operation the author marked the lack of the distinctions in dysplastic and primary coxarthrosis.Conclusions. Proprioceptive regulation was broken in degenerative-dystrophic hip joint diseases in spite of their causes. Somatosensor insufficiency alterations in patients with dysplastic and idiopathic coxartrosis were minimal because nervous system was able to adapt having reinforced the load on the receptors. In fast coxarthrosis progression the adaptation mechanism had no time to develop and it reflected on more significant proprioceptive deficiency after arthroplasty.
