The hips were divided into four groups according to the Tonnis radiographic dislocation classification. Groups were also classified according to the baseline acetabular index (AI): 30\u00b0\u201335\u00b0, 36\u00b0\u201340\u00b0, and\u2009&gt;\u200940\u00b0.

After 3 months of orthosis fixation, the results were satisfactory in 264 hips (77.88%). Hip function was rated as \u2018excellent\u2019 or \u2018good\u2019 in 43 of 51 (84.31%) Tonnis type 1 hips, 125 of 155 (80.65%) type 2 hips, 70 of 90 (77.78%) type 3 hips, and 34 of 43 (79.07%) type 4 hips. The higher the baseline AI, the lower the rates of \u2018excellent\u2019 and \u2018good\u2019 hip function. Favourable radiological results (Severin types I and II) were found in 266 of 339 (78.47) hips.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
