Clinical Study Of Acetabular Development After Closed Reduction Of Developmental Dislocation Of The Hip

Objective: This study through the retrospective study,observation after closed reduction method is used in henan luoyang bonesetting hospital clinical curative effect,treatment of DDH analysis of DDH after closed reduction and the characteristics and regularities of the variation of the acetabulum development,explore the factors which influence the development of acetabulum after reset and its feasibility of treatment of DDH,summarizes the advantages and disadvantages of closed reduction method,find out the cause of the reduction of complications after and prevention method,for improving DDH treatment curative effect to provide the reference.Methods: Follow-up in January 2010-December 2014 in henan province,luoyang bonesetting hospital a total of 50 cases with closed reduction method of treatment for children with DDH in all unilateral illness,age of 3 to 24 months,with age group for the unit,a total of four groups of three to six months,respectively,7 to 12 months,13 to 18,19-24 months group,with the same period the contralateral hip with control group,side hip function to evaluate the clinical curative effect evaluation of level 4.Dynamic measuring the healthy side of each age group of children and the acetabulum index(AI)of the hip and acetabulum depth and width ratio(D/W)(AI)numerical changes of follow-up time is one year,once every three months measurement(reset,reset after 1 to 3 months before,4 to 6 months,7-9 months,10-12 months).Analysis of each age group,each observation period between the healthy side,the same characteristics and laws of the development of acetabulum compare all age groups and the time to watch the healthy,the differences of acetabulum development of side.All the data statistics processing adopts SPSS19.0 to complete.Results: A total of 50 cases of children with DDH with closed reduction and 12 months after the function of the evaluation results,27 cases,14 cases,3 cases,6 cases,poor overall fine rate was 82.00%.Average dropped from 37.48 ° of AI to 26.77 °,by an average of 10.07 °,AI(D/W)average of 20.34% and 30.43%,grew by an average of 9.20%,the rate of decline in the affected AI,AI(D / W),the growth rate faster than the contralateral.Average decline of AI and AI(D/W)rise in the average degrees of comparison: 1-3 months,falling speed of 10 to 12 months of AI and AI(D/W)are growing significantly faster than the other,with 1-3 month4-6,7-9 months between rate of descent and AI AI(D/W)growth compared with significant difference(P<0.01),10-12 months between 4-6,7-9 month rate of descent and AI AI(D/W)growth compared with significant difference(P<0.01).Year average decline in each age group of AI and AI(D/W)average growth level comparison: 3-6 months of age group,7 to 12 months of the rate of descent and AI AI(D/W)are growing significantly faster than the other months group,3-6 months and 13 to 18 months of age groups,19-24 months of age group of rate of descent and AI AI(D/W)growth compared with significant difference(P<0.05),7-12 months and 13 to 18 months of age group,19-24 months of age group of rate of descent and AI AI(D/W)growth compared with significant difference(P<0.05),3-6 months of age group and 7 to 12 months,13 to 18 months of age groups and 19 to 24 months of age group rate of descent and AI AI(D/W)compared the growth rate of no significant difference(P>0.05).Conclusion: The closed reduction and conservative therapy has a better clinical therapeutic effect of conservative treatment is still worthy of popularization and application.The speed of the ipsilateral acetabular developmental dislocation of the hip is significantly faster than the healthy side.1 to 3 months after closed reduction,10-12 months is the same height of the development of acetabulum within 12 months of age children with bilateral acetabulum fastest development,of children older than 12 months of acetabulum development is relatively slow.In general the smaller the age of acetabulum development speed faster.The better therapeutic effect,new age,degree of dislocation,whether concentric reduction are the main factors influencing the acetabulum development speed.
