Object: To investigate The rehabilitative guidance via wechat platform on postoperative dirigation of children with DDH. Methods: After plaster immobilization, 32 children with a comprehensive nursing intervention are compared to 37 with traditional nursing. X-ray is employed to examine and record the therapeutic effect based on the evaluation standard of DDH. The clinical outcome, X-ray results, overall acceptance rate, compliance and the subluxation rate are compared between the two groups. SPSS 17.0 statistical software is applied for statistical analysis. Results: 1. The compliance in the intervention group in the 6th week is significantly better than the traditional group (p<0.05). 2. The clinical outcome, X-ray results, overall acceptance rate, and compliance in the intervention group in the 3th and 4th month are significantly better than the traditional group (p<0.05). 3. The clinical outcome, X-ray results, overall acceptance rate, compliance and subluxation in the intervention group in the 5th and 6th month are significantly better than the traditional group (p<0.05).Conclusion:A comprehensive intervention in hospital and postoperative rehabilitative guidance via WeChat can not only improve the clinical evaluation, X-ray evaluation, but also the compliance of children with family members, thus improve children's overall crop. Introduction Developmental dislocation of the hip joint is a common ailment. For moderate and severe children aged from 1.5 to 8, the sooner the operation is made, the better the result will be. On clinical stage, hip-shelf procedure femoral rotational osteotomy orthopedy will be performed, postoperative plaster immobilization will last for 6 weeks. However, the stitches will be taken out 14 days after the operation, while the plaster will be remained when leaving the hospital. Literally, the clinical stage is terminated. Large space is left for rehabilitative guidance on how to provide assistance to the child, which has great influence on dirigation of the hip joint as well as his gait. Research Subject and Methodology Research Subject. Children with developmental dislocation of the hip joint who are in hospital between Jan. 2013 to May 2014 and meet the requirements of research are chosen as the subjects. Research requirements are: 1. Children who are diagnosed as developmental dislocation of the hip joint; 2. Children who will be performed hip-shelf procedure femoral rotational osteotomy orthopedy, and postoperative plaster immobilization will last for 6 weeks, the stitches will be taken out 14 days after the operation, while the plaster will be remained when leaving the hospital; 3. Children who are unilaterally operated and initially operated, aged from 1.5 to 8; 4.
