Trial Title: A Prospective Randomized Controlled Trial on the Use of Bone Morphogenetic 7 (BMP-7) (OP-1®) and Demineralized Bone Matrix in Tibial Non-union

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT

- Phase: PHASE4
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* 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~Exclusion Criteria:~* 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

Study Arms:
- 2 (Type: ACTIVE_COMPARATOR): non-union of diaphysary tibial fractures will be treated with allograft together with DBM
- 1 (Type: EXPERIMENTAL): non-union of diaphysary tibial fractures will be treated with BMP-7 in adjunct to fresh frozen allograft

Based on this trial design, predict the completion outcome and termination type (if applicable).
