title: The effect of Dega acetabuloplasty and Salter innominate osteotomy on acetabular remodeling monitored by the acetabular index in walking DDH patients between 2 and 6 years of age: short- to middle-term follow-up.
abstract: BACKGROUND
  The surgical management of neglected developmental dysplasia of the hip (DDH) in walking children has always been a challenge to orthopedic surgeons. The aim of this study was to evaluate the short- to middle-term clinical and radiographic results of the management of DDH.
  
  
  METHODS
  Patients less than 6 years old using two of the most commonly used osteotomies, namely, Salter innominate osteotomy and the Dega acetabuloplasty. Special attention was paid to acetabular remodeling after concentric reduction, which was monitored by the acetabular index, that, in turn, was measured preoperatively, immediately postoperatively, every 6 months, and at the final follow-up examination.
  
  
  RESULTS
  The final overall clinical end results were favorable (excellent or good) in 93 hips (85.3 %). There was a marked improvement of the acetabular coverage during the follow-up period, which proved the good remodeling potential of the acetabulum for this particular age group after concentric reduction was achieved and maintained.
  
  
  CONCLUSIONS
  Both osteotomy types were found to be adequate for the management of neglected walking DDH patients under the age of 6 years.
