Is the extensive anterolateral approach for the treatment of developmental dysplasia of the hip more favorable than conventional surgical methods?
Radiological results of extensive anterolateral approach for the treatment of 16 hips with developmental dysplasia of the hip were reported. The mean age of the patients was 13.3 months at the time of the operation and they were followed up for a mean of 75.6 months. Only one (6.3%) hip was redislocated as a complication. At the final follow-up, 14 (87.5%) hips were classified as class I or II according to the Severin classification 1.
We reported previously long-term outcome of medial open reduction of 110 hips with developmental dysplasia of the hip 2. The mean age of the patients was 17.71 months at the time of the reduction and the mean duration of follow-up was 13.97 years. Four (3.6%) hips required secondary surgery for redislocation. We obtained class I or II results in 86.37% of hips according to the Severin classification 2. Similar results could be obtained with smaller and less extensive approaches such as the medial approach.
We thank Sugawara and colleagues, but would like to conclude that their results were not more favorable than conventional methods, and the patient numbers and follow-up period were limited for such a conclusion.
