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.

Detailed Description

Quality assurance plan：All the investigators will receive uniform training. Standard cases follow-up,collection,management systems will be established.The process of cases follow-up,collection,management will be supervised by the third party.Data entry will be in the manner of independent parallel entry.The endpoints events are judged by third party.Statistical analysis are implemented by the statistics institutions of the third party.In order to control the bias,this study takes multicenter,random,control study design.

Sample size assessment:Under the condition of multicenter,random,control design, computational formula takes the rate comparisons of two groups.The key endpoints event is soft tissue width of vertebral side measured by computed tomography. The incidence of the key endpoints event in two weeks group is 30%.The incidence of the key endpoints event in four weeks group is 15%.When alpha value is 0.5 and power value is 0.9,the sample size is 161 patients.If loses visit rate is 20%,the sample size is 194 patients.

Statistical analysis plan:The key events are analyzed by chi-squared test.The statistical significance factors among them are calculated by relative risk.

Data checks and source data verification are supervised by a third-party organization (contract research organization，CRO).

Standard Operating Procedures:Investigator's brochure has explained in detail about the standard operating procedures of everything.Data dictionary can be found in standard operating procedures.

Plan for missing data: The investigators Set a 20% rate of lost to follow-up.

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.

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
Time Frame
Vertebral side width of soft tissue is measured by CT after operation.
Time Frame: up to 3 months
up to 3 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Amount of bone trabecula between bone graft surfaces is measured by X-ray after operation.
