Treatment of aseptic osteonecrosis of the talus. A draft of clinical guidelines

Clinical guidelines are an algorithm adapted for use in our country, based on the works systematized by the level of evidence, reflecting current approaches to the diagnosis and treatment of aseptic bone necrosis (osteonecrosis) of various localizations. Purpose of the study Creation of an algorithm for diagnosis and treatment of osteonecrosis based on the assessment of the evidence level of literature data. Material and methods The Guidelines are a systematized algorithm based on the level of evidence for the management of patients with osteonecrosis, reflecting current approaches to diagnosis, treatment and rehabilitation, which are based on literature data and the authors' own experience. Electronic databases of Medline, Embase, Web of Science, and Cochrane Library platforms were searched for related sources. Preference was given to the works with high levels of evidence. References to information sources are given in the order of their appearance in the text. The search depth was 50 years due to the availability of systematic literature reviews in the framework of previous international clinical guidelines. When specific medical procedures related to the diagnosis, conservative or surgical treatment of osteonecrosis were included in the clinical recommendations, their level of evidence was reliability, the appropriateness of their use, taking into account the unified scale for assessing the quality of evidence and the strength of the recommendations for application of medical technologies GRADE. Results The Guidelines reflect aspects of clinical, instrumental and laboratory examination of patients with osteonecrosis, treatment options depending on the location of the process and disease stage. Conclusion Clinical recommendations on the medical assistance to patients with aseptic osteonecrosis have been compiled according to the requirements imposed on clinical recommendations developed by medical professional non-profit institutions.
