Studies reporting the outcomes for these procedures generally rely on a combination of radiographic and clinical outcomes. However, there is not currently a standardized radiographic scoring system that allows for objective reporting of radiographic outcomes following these procedures. This article introduces a novel scoring system (Beijing University of Chinese Medicine X-ray evaluation, BUCMXE) based on Anteroposterior (AP) hip radiographs to allow for objective evaluation and comparison of postoperative outcomes following joint-preserving treatments for ONFH.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>The proposed scoring system utilizes AP radiographs of the hip and consists of a total score (0-10) derived from the sum of subscores in 3 domains: femoral head morphology, osteonecrotic lesion, and degree of osteoarthritis. Each radiographic parameter is scored from 0 (normal) to 3 or 4 (advanced disease). The scoring model was retrospectively applied to a cohort of patients who had undergone core decompression and cancellous bone grafting procedures by the principal investigator.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The BUCMXE provided a clear and reproducible means of quantifying and communicating radiographic changes over the course of follow-up in our study cohort. Statistical analysis demonstrated that the BUCMXE was sensitive to detect the radiographic changes associated with the index procedure. The median total score was reduced from 3 preoperatively to 2 at the initial (3-month) follow-up for this cohort. This change was attributable to the obvious improvement of osteonecrotic lesion in patients who had more advanced disease at the time of their procedure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The BUCMXE system allowed for objective quantification of radiographic changes following joint-preserving hip surgery in our cohort.
