A study to evaluate if the patients own stem cells combined with biomaterial will be effective and safe in bone healing in patients with fractures in the leg or arm, that did not heal with conventional treatment.

Evaluation of safety and feasibility of autologous MSCs combined to biomaterial to enhance bone healing in patients with delayed consolidation after long bone defects requiring graft apposition or alternative orthobiologics - Behandling, Orto

Inclusion criteria

Inclusion criteria: The inclusion criteria are: - Age 18 to 65, both sexes - Traumatic isolated closed or open Gustilo-Anderson I, II or IIIa humerus, tibial, ulna or femur - diaphyseal or metaphysodiaphyseal fracture with a bone loss of 2-10 cm. - Able to provide informed consent, and signed informed consent - Patients (by themselves) should have medical health care coverage to be included in a research study. - Able to understand and accept the study constraints To further standardize the inclusion, patients to be included will be those that alternatively would have received bone autograft and/or BMPs, thus avoiding (excluding) segmental defect patients to be treated with large allografts. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 10 F.1.3 Elderly (>=65 years) no F.1.3.1 Number of subjects for this age range

Exclusion criteria

Exclusion criteria: The non-inclusion criteria are: - Pregnancy, breast feeding women and women who are of childbearing age and not practicing adequate birth control - Participation in another therapeutic trial in the previous 3 months - Delayed union or non-union related to iatrogeny - Segmental bone loss requiring specific therapy (bone transport, large structural allograft, megaprosthesis, etc) - Vascular or neural injury - Other fractures causing interference with weight bearing - Infection: skin, soft-tissue, bone or any remote infection (dental, pulmonary, gynecological) - Visceral injuries of diseases interfering with callus formation - (craneoencephalic trauma, etc.) - History of bone harvesting on iliac crest contraindicating bone-marrow aspiration - Corticoid or immunosuppressive therapy more than one week in the three months prior to study inclusion - History of prior or concurrent diagnosis of HIV-, Syphilis, Hepatitis-B- or Hepatitis-C-infection (confirmed by serology or PCR) - Subject legally protected, under legal guardianship, deprived of their liberty by judicial or administrative decision, subject of psychiatric care, or admission to a health facility. - Impossibility to meet at the appointments for the follow up - Insulin dependent diabetes - Obesity (BMI > 30) - Autoimmune inflammatory disease - Current treatment by biphosphonate or stopped in the three months prior to study inclusion.

Design outcomes

Primary

MeasureTime frame
Main Objective: To assess the safety of apposition of biomaterial with autologous MSCs at the fracture site.;Secondary Objective: To obtain consolidation, without increasing the complication rate, of diaphyseal and/or metaphysodiaphyseal fractures (femur, tibia, humerus) status delayed union (after 3 months) treated by standard care procedures plus apposition of biomaterial with autologous MSCs at the fracture site.;Primary end point(s): Proven bone healing ;Timepoint(s) of evaluation of this end point: 12 and 24 weeks

Secondary

MeasureTime frame
Secondary end point(s): - Amount of radiological callus at 12 weeks, and 26 weeks. - Clinical consolidation at weeks 12, 24. - No reoperation done or scheduled at 26 weeks. - Changes in serum levels of bone turnover markers (in a centralized laboratory) at 6, 12 and 26 weeks after treatment: the following markers will be evaluated by immunoenzymatic assays on serum samples on all recruited patients ;Timepoint(s) of evaluation of this end point: 6, 12 and 24 weeks
