- Abstract:
- Objective To compare the clinical outcomes after open reduction with and without femoral shortening for children aged 2 to 3 years with Tonnis grade Ⅱ developmental dysplasia of the hip(DDH).Methods From January 2016 to December 2017,48 children aged 2 to 3 years with Tonnis grade ⅡDDH(48 hips)were retrospectively reviewed.There were 21 hips in femoral non-shortening group and 27 hips in femoral shortening group.The average age was 28.6(25-34)months.The Severin criteria were used for evaluating the imaging scores.And avascular necrosis(AVN)and redislocation rate were employed for judging the therapeutic outcomes.Results The mean follow-up period was 22.1(17-27)months.Femoral non-shortening group:2 AVN cases(2/21,9.5%),the outcomes were excellent(n=19)and decent(n=2)using the modified McKay criteria,excellent(n=17)and decent(n=4)using the Severin scale,no redislocation;femoral shortening group:3 AVN cases(3/27,11.1%),excellent(n=23)and decent(n=4)using the modified McKay criteria,excellent(n=20)and decent(n=7)using the Severin scale and no redislocation.No statistically significant differences existed in modified McKay criteria,Severin score or AVN rate.Conclusion Femoral shortening is not recommended for children aged 2-3 years with Tonnis gradeⅡ DDH.
