Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Umbilical cord blood mononuclear cells are a type of cell group containing hematopoietic stem cells, mesenchymal stem cells, neural stem cells, endothelial cells, immune cells, etc.In this study ,umbilical cord blood mononuclear cells will be used in promoting traumatic fracture healing,and the effectiveness and safety of the treatment plan was evaluated by twelve months of follow-up after treatment.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 71 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Traumatic long bone fracture.
  • Noninfectious bone nonunion, delayed bone union.
  • 3 months after the operation of the fracture, the examination showed no callus growth, no signs of progressive repair at the fracture site, fracture piece space < 5mm.
  • No shortening, angulation and displacement.
  • There was no obvious callus growth 8 months after local bone grafting.

Exclusion Criteria:

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Bone formation
Time Frame: 1 month to 1 year after treatment
If there is no bone formation, 0 points. Bone formation accounts for 25% of the fracture area, 1 point. Bone formation accounts for 50% of the fracture area, 2 points. Bone formation accounts for 75% of the fracture area, 3 points. Bone filled the gap between fracture ends, 4 points.
1 month to 1 year after treatment
Bone defect connection
Time Frame: 1 month to 1 year after treatment
0 points for complete fracture lines, 2 points for partial fracture lines, 4 points for lack of fracture lines.
1 month to 1 year after treatment
Bone reconstruction
Time Frame: 1 month to 1 year after treatment
0 points for no manifestations of reconstruction,2 points for intramedullary cavity can be reconstructed , and 4 points for the cortical bone can be completely reconstructed. A total score of 11 points or more achieves a good healing effect.
1 month to 1 year after treatment

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
