AIM: Hip dysplasia is one of the most common skeletal disorders. As a late consequence 20-25% of the patients are at risk to develop secondary osteoarthritis and may require total hip replacement early in life. The treatment principles of hip dislocation are (1) concentric reposition, (2) retention, i.e., plaster in human post or Pavlik harness and (3) maturation in abduction flexion orthesis. The Tübingen splint was introduced as a further development of abduction devices for the treatment of (residual) hip dysplasia with stable hips. The advantages are easy handling, adjustment according to growth and safe limitation of abduction. The aim of this study was to determine the success of treatment of unstable hips with use of the Tübingen splint from early diagnosis until final end of therapy hence normal ultrasound findings. METHODS: From January 2003 to August 2016 79 children with 109 sonographic unstable hips were treated with the Tübingen splint initially consequently 24 h/day. Inclusion criteria were diagnosis of type D, type III a/b or type IV hips according to Graf and beginning of treatment at an age of less or equal 6 weeks, without limitation of abduction on clinical examination. RESULTS: At the time of diagnosis 51 type D (46.8%), 46 type III (42.2%) and 12 type IV (11.0%) hips were noticed. In 30 patients (38.0%) bilateral hip dysplasia (type D-IV) was diagnosed. 104 of 109 hips (95.4%) treated with the Tübingen splint could be transferred in a type I hip after a mean treatment period of 88.9 days (SD ± 26.0). In 5 cases (4.6%, 1 type III and 4 type IV hips) the treatment failed. CONCLUSION: Our data show, that successful treatment of unstable hips in neonates with the Tübingen splint is a comparably successful treatment modality relative to the Pavlik harness and Fettweis plaster.
