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
Measure Description
Time Frame
Fusion rates
Time Frame: up to 5 year after operation
This is assessed by postoperative computed tomography at 1 year after surgery
up to 5 year after operation

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
Measure Description
Time Frame
Visual Analog Pain Scale (VAS)
Time Frame: 3, 6, and 12, months, and every year, up to 5 year after operation
VAS is a measurement score that indicates pain severity status. VAS score comprised a 10-cm line with ''none'' (0) on one end of the scale and ''disabling pain'' (10) on the other.
3, 6, and 12, months, and every year, up to 5 year after operation
Oswestry Disability Index (ODI)
Time Frame: 3, 6, and 12, months, and every year, up to 5 year after operation
The ODI is based on a self-administered questionnaire measuring ''back-specific function.'' The questionnaire comprises 10 items, each with 6 levels of response. Each item is scored from 0 to 5, and the total summation is converted to a 0-100 scale.20 The ODI scores ranges from 0 to 100, with higher scores indicating severe symptoms.
3, 6, and 12, months, and every year, up to 5 year after operation
EQ-5D
Time Frame: 3, 6, and 12, months, and every year, up to 5 year after operation
EQ-5D is a standardized instrument developed by the EuroQol Group as a measure of health-related quality of life that can be used in a wide range of health conditions and treatments. The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. This can be used as a quantitative measure of health outcome that reflects the patient's own judgement. The scores on these five dimensions can be presented as a health profile or can be converted to a single summary index number (utility) reflecting preferability compared to other health profiles.
3, 6, and 12, months, and every year, up to 5 year after operation
PainDETECT
Time Frame: 3, 6, and 12, months, and every year, up to 5 year after operation
The painDETECT Questionnaire (PDQ) is a screening tool designed to detect neuropathic pain in patients with chronic low back pain (LBP) based on self-reported pain characteristics. The degree of the seven types of pain quality, the type of pain pattern, and the presence of radiating pain. From the three components of the PDQ, a total score is calculated; a high score indicates that the pain is likely to have a neuropathic component. Scoring is performed using a scoring manual, and results in a final screening score: a score of 0-12 indicates nociceptive pain, 19-38 indicates neuropathic pain, and 13-18 indicates mixed pain.
3, 6, and 12, months, and every year, up to 5 year after operation
Fusion rates
Time Frame: every year, up to 5 year after operation
This is assessed by postoperative simple radiography at 1 year after surgery
every year, up to 5 year after operation
Number of participants with treatment-related adverse events as assessed by CTCAE v4.0
Time Frame: every year, up to 5 year after operation
Device related adverse events (fracture, translation, subsidence, osteolysis), Surgery related adverse events (incidental durotomy, wound infection, re-operation, re-admission)
every year, up to 5 year after operation

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Operation duration
