<p> <strong> Abstract </strong></p><p> <strong> Background: </strong>To evaluate proximal junctional segment changes in Adolescent Idiopathic </p><p> Scoliosis(AIS) the posterior spinal fusion and also instrumentation also and </p><p> finding of probable risk factors, were all considered in this study. </p><p> <strong> Methods: </strong>We retrospectively reviewed radiographs of 121 consecutive patients </p><p> who underwent posterior spinal fusion for AIS from T3 or below, with a mean follow- </p><p> up of 32.8 months(range,24-83). All coronal and sagittal measurements including </p><p> the proximal junctional kyphosis (PJK)angle recorded on standing anteroposterior </p><p> and lateral radiographs preoperative, early postoperative and on follow-up radiographs. </p><p> The data were analyzed using the Spss 10.0 software. Dependent(paired) </p><p> samples student t-test was used for analysis between the groups </p><p> <strong> Results: </strong>There was PJK angle above normal for the same junctional segment preoperatively in 13 patients (10.7%) and the incidence of the PJK postoperatively was </p><p> 7.4% (9 patients, 7 female and 2 male), all detected until 2 years postoperation.The </p><p> mean increase in the PJK angle from pre-operation until 6 weeks postoperation was </p><p> 5.9° (range,0-13°)(P=0.02) and until 2 years post operation was 14.3° (range, 2- </p><p> 16°)(p=0.000). The mean proximal junctional angle increased 1.6° until 2 years postoperation in non-PJK group(n=112). </p><p> <strong> Conclusion: </strong>The prevalence of Proximal Junctional Kyphosis was low and a </p><p> silent radiographic problem. In some cases is preventable with perfect pre-operative </p><p> planning. There is no specific demographic or radiographic variables or instrumentation </p><p> types associated with developing PJK . </p>
