Pavlik Harness treatment may help accelerate development of acetabulum in patients less than 6 months old
Yong Liu et al conducted a study to investigate the impact of failed Pavlik harness (PH) treatment on the outcomes following closed reduction (CR) or open reduction (OR) in developmental dysplasia of the hip (DDH). They found that PH treatment, even if failed, may have the ability of accelerating the development of the acetabulum and increasing the rate of successful CR. Thus the authors advocate a trial of PH treatment for all DDH patients less than 6 months of age.
The primary goal of the treatment in DDH is to achieve a stable and concentric reduction as early as possible so as to facilitate normal development of all structures of the hip while avoiding complications. Failure of PH treatment and late-diagnosed DDH are still commonly encountered. Usually, in these patients, a closed or open reduction is considered for further treatment.
Ninety-three DDH patients treated with CR or OR were enrolled. One group of which received previous PH treatment (F group) and the other (L group) not. The clinical outcomes were evaluated according to McKay's criteria. Radiographs were evaluated for acetabular index (AI) and the degree of dislocation of the hips.
