Comparison between the Pavlik harness and the Tübingen hip flexion splint for the early treatment of developmental dysplasia of the hip

The Pavlik harness and the Tübingen hip flexion splint (Tübingen hip flexion splint) are two effective options for the early management of patients younger than 6 months of age with developmental dysplasia of the hip (DDH). The main objective of this study was to evaluate the clinical and radiological outcomes of patients younger than 6 months of age with type IIb to IV DDH managed by Pavlik harness or Tübingen hip flexion splint. The Pavlik harness and Tübingen hip flexion splint groups were comparable regarding the affected side (P = 0.09), Graf grade (P = 0.635), and age at initial treatment (P = 0.77). Overall, failure rates were 12 and 33% in Pavlik harness (4/33 hips) and Tübingen hip flexion splint groups (14/43 hips), respectively (P = 0.038). No cases of avascular necrosis (AVN) were found in either group. In the Tübingen hip flexion splint group, the failure rate was significantly higher in bilateral cases (66.6%; P = 0.004), in severe forms (Graf grade IV hips; P ≤ 0.0001), and in patients with lower age at initial treatment (67.7 ± 39.3 days; P = 0.005). The average follow-up time was 30.35 ± 3.58 months (range: 24–36). At the last follow-up visit, no statistically significant differences were found between the Pavlik harness and Tübingen hip flexion splint group...
