title: [Biorhythmical characterization of exacerbations of the degenerative-dystrophic process in patients with the impaired hip joint].
abstract: The age-dependent structure of the contingents treated conservatively at the local outpatient clinics (197 women aged 17-82 and 59 men aged 25-85) and patients subjected to operations of total endoprosthesis of the hip joint for coxarthrosis (663 women aged 19-89 and 304 men aged 22-82) was investigated. The structure of the indices under study was found to fluctuate with the average period length 10.7 years (sigma = 2.7 years), 8.2 years (sigma = 3.5 years), 7.3 days (sigma = 3.0 years), 9.5 years (sigma = 2.1 years) respectively. A comparison of the fluctuation curves of the age-dependent structure of the women treated conservatively and operated upon showed the coincidence of the maximums in 35, 43, 60, 65, 69, 74-74 years of age, in men--in 34-35, 41, 75-76. It can be supposed that the revealed age-dependent fluctuations of activity of the inflammatory process and the pain syndrome correspondingly might be considered as an element of the periodic disease in pathogenesis of degenerative-dystrophic lesions of the hip joint.
