简要总结

The researchers propose a prospective, randomised partially-blinded study to investigate the clinical and radiological outcome, effect on quality of life and socio-economic impact of non-union of diaphysary tibial fractures treated with BMP-7 in adjunct to fresh frozen allograft, in comparison to treatment with allograft together with DBM (demineralised bone matrix).

入选标准

  • Diaphysary tibial non-unions will be included (9 months after first surgery)
  • Major surgery includes exchange nailing, bone grafting, internal fixation, amputation and soft-tissue coverage procedures, such as delayed primary closure and free flaps
  • Surgery is classified as minor for removal of external fixator pins for local infection and removal of a static locking screw from intramedullary nails, a procedure known as dynamization
  • ASA 1 and ASA 2
  • Gap length/bone contact detected (1-5 cm): largest cortical gap in any radiographic incidence
  • Subject or legal guardian is willing and able to understand, sign and date the study specific Patient Informed Consent, which has been approved by the Institutional Review Board
  • Agrees to participate in post-operative evaluations and required rehabilitation regimen

排除标准

  • Patients with known hypersensitivity to the active substance or collagen
  • Gap more than 5 cm
  • Immature skeleton
  • Known auto-immune disease, including rheumatoid arthritis, systemic lupus erythematosus, scleroderma, Sjögren's syndrome and dermatomyositis/polymyositis
  • Active infection on unhealed site or active systemic infection
  • Non-healing resulting from pathological fractures, tumours or metabolic bone diseases
  • Presence of tumour in vicinity of non-union
  • Patients receiving chemotherapy, radiotherapy or immunosuppressant treatment or excessive steroids
  • Patients with severely compromised soft tissue coverage or vascularisation at the non-union site, sufficient to impair bone healing
  • Patients with congenital non-union
  • Pregnancy and lactation
  • Non-union of multiple bones interfering with walking
  • Patients with neuromuscular diseases or conditions interfering normal weight bearing
  • Patients who, judged by the surgeon, are candidates for just internal fixation alone
