The purpose of this study was to evaluate the effect of the WISH brace on radiographic images of the hip joints of patients with hip arthrosis and to examine the factors that may cause changes in radiographic images after one year of treatment.
The CE angle and Kellgren and Lawrence classification (K-L classification) were evaluated from X-ray images taken in the supine position with both hip joints in 10-15° internal rotation in the front and rear views at the time of brace creation (before brace: 0 months) and one year after brace application (12 months). Height, age, weight, BMI, and HHS were measured at 0 and 12 months to evaluate hip function.
The CE angle was significantly smaller on the braced side at 12 months than on the orthotic side at 0 month. HHS improved significantly at 12 months on both the braced side and unbraced side.
The narrowing of the joint crease and outward displacement of the head were progressive during conservative treatment with the WISH-type hip orthosis, suggesting that it would be difficult to control or improve the abnormal position of the head. However, the WISH-type hip brace is an option for conservative treatment because it significantly improved hip function by reducing hip pain within one month after the brace was applied, and this improvement lasted for at least one year.
The results will be reflected in physiotherapy patient management.
