Following institutional ethics approval, a total of 57 patients (49 Female, eight Male) with ASD underwent surgery fused to sacroiliac bone (S1, S2, or ilium) from March 2014 to January 2019 were included. All of those patients were followed up for at least 2\u2009years. Demographic, radiographic and surgical data were recorded. The maximum range of flexion motion (F\u2010ROM) and extension motion (E\u2010ROM) actively of hip joints was measured and recorded at pre\u2010 and postoperation. The sum of F\u2010ROM and E\u2010ROM was defined as the range of hip motion (H\u2010ROM). Receiver operating characteristic (ROC) curve analysis was used to obtain the cut off value of parameters for PJF. A Kaplan\u2013Meier curve and log\u2010rank test were used to analyze the differences in PJF\u2010free survival.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In all, 14 patients developed PJF during follow\u2010up. Comparisons between patients with and without PJF showed significant differences in immediate TK (<jats:italic>P<\/jats:italic> &lt;\u20090.001) and AA (<jats:italic>P<\/jats:italic> =\u20090.027) postoperatively. ROC curve analysis determined an optimal threshold of 13\u00b0 for immediate AA postoperatively (sensitivity\u00a0=\u00a074.3%, specificity\u00a0=\u00a085.7%, area under the ROC curve [AUC] =\u20090.806, 95% <jats:italic>CI<\/jats:italic> [0.686\u20130.926]). Nineteen patients with post\u2010AA \u226413\u00b0 were assigned into the observational group, and 38 patients with post\u2010AA &gt;13\u00b0 were being as the control group. Patients in the observational group had smaller H\u2010ROM (<jats:italic>P<\/jats:italic> =\u20090.016) and F\u2010ROM (<jats:italic>P<\/jats:italic> &lt;\u20090.001), but much larger E\u2010ROM (<jats:italic>P<\/jats:italic> &lt;\u20090.001). There were 10 patients showing PJF in the observational group and four in the control group (10\/9 <jats:italic>vs<\/jats:italic> 4\/34, <jats:italic>P<\/jats:italic> &lt;\u20090.001). PJF\u2010free survival time significantly decreased in the observational group (<jats:italic>P<\/jats:italic> =\u20090.001, log\u2010rank test). Furthermore, patients in the observational group had much larger TK (post\u2010TK, <jats:italic>P<\/jats:italic> =\u20090.015). The optimal threshold for post\u2010TK (sensitivity\u00a0=\u00a085.7%, specificity\u00a0=\u00a076.7%; AUC\u00a0=\u00a00.823, 95% <jats:italic>CI<\/jats:italic> [0.672\u20130.974]) was 28.1\u00b0 after the ROC curve was analyzed. In the observational group, those patients with post\u2010TK \u226528.1\u00b0 had significantly higher incidence of PJF (9\/2 <jats:italic>vs<\/jats:italic> 1\/7, <jats:italic>P<\/jats:italic> &lt;\u20090.001) than those with post\u2010TK &lt;\u200928.1\u00b0.
