The purpose of this study was to analyse the complications using the Bailey-Dubow expanding intramedullary rods in patients with osteogenesis imperfecta. Between 1985 and 1996 intramedullary rodding of 107 long bones with expanding Bailey-Dubow rods was performed in 29 patients suffering from osteogenesis imperfecta. Indications for using rods included osseous deformities and bone deformities in combination with fractures. The average follow-up was 3.5 years (range 2 months to 9 years). The total complication rate in these patients was 63.5% (68 rods). The main complication was rod migration often combined with perforation of joint, bone and soft tissue. Additionally, there was a high incidence of new fractures as well as refractures. Other complications like infections, pseudarthrosis, lack of elongation or over-elongation of the rods, and loosening of the T-piece were only rarely seen. Based on our experience and the information available in the literature, the Bailey-Dubow rod is currently the most successful way to stabilize the growing long bones of patients suffering from osteogenesis imperfecta. However, when using this device, the surgeon as well as the parents of the patient must be aware of the high incidence of complications.
EinleitungCa. 50 % aller Gelenkluxationen betreffen das weichteilgeführte Schultergelenk, das beweglichste Gelenk des menschlichen Körpers. Die passiven und aktiven Stabilisatoren haben die fehlende knöcherne Formgebung zu kompensieren. Der kapsulo-labro-ligamentäre Komplex stabilisiert mechanisch und führt über neurophysiologische Reizimpulse von Mechanorezeptoren und freien Nervenendigungen zur Aktivierung der aktiven Stabilisatoren -Deltamuskel, Rotatorenmanschette und lange Bizepssehne.Die Schulterinstabilität wird von Gerber [2] als der Verlust der Kontrolle über die Zentrierung des Humeruskopfes in der Gelenkpfanne definiert.Die Instabilität kann nach ihrer Ursache unterteilt werden in die Expert opinion of traumatic shoulder instability for health insurance companies Abstract To answer the question, if the complaints of a patient with an instability of the shoulder are related to an accident, it is important to know something about the possible causes of an instability and the clinical, radiological and (if
