The MRI findings were compared with those in anatomic sections and histological preparations. A total of 459 patients with lateral epicondylitis from 3 hospitals\u2009were included\u2009and divided into a nonoperative treatment failure group (n = 138) and a nonoperative treatment success group (n = 321). The prognostic prediction model for nonoperative treatment was developed using the logistic regression method. Model 1 was based on logistic regression results, and model 2 was model 1 with the parameter of RHSP syndrome removed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The RHSP is contiguous with the radiohumeral articular capsule and subtly mingles with the lateral collateral ligament (LCL) complex and common extensor tendon (CET), forming an enthesis. Furthermore, the authors found that patients in the nonoperative treatment failure group had greater RHSP dimensions and a higher prevalence of RHSP syndrome (all\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .05). In addition, sex, RHSP syndrome, size of CET tear, grade of LCL complex abnormality, and muscle edema were independent predictors of failure for nonoperative treatment. The AUC of model 1 (0.839; 95% CI, 0.796-0.881) was significantly higher than that of model 2 (0.805; 95% CI, 0.760-0.851) (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .024).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The authors developed a model to predict the failure of nonoperative treatment in patients with lateral epicondylitis.
