Correlation Between the Lower Extremities and Lumbar Degenerative Diseases of the Elderly and Formulation on Treatment Principles

The study has before mentioned the concept of "knee - spine syndrome" domestically, on the basement of which, the new study intends to perform another further study on the relationship between lumbar and lower extremity degenerative diseases.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

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

A prosepective, single-center, factorial design, randomized study will be performed. In this study, the 120 participants with degenerative lumbar and knees disease coped with the standard were included, then were assigned into 4 groups randomly. The patients in 3 operation groups were treated with posterior lumbar interbody fusion(PLIF or PLF) or total knee arthroplasty (TKA) or both of them in one stage respectively and the forth group with no surgery. The comparison between observation and operation group and the difference on self-control pre-and post-operatively in operation group within 6 months were measured and valuated. The result will be formed by the correlation and causal relationship on sagittal parameters on photograph, biomechanics, neuroelectrophysiology and molecular biology and the conclusions drawn by the use of modern medical basic research methods will formulate the treatment principles on it.

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

50 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

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
Body angle
Time Frame: 6 months
Body angle is defined an angle of the shoulder and femoral trochanter connection and the greater trochanter and knee lateral condyle connection.
6 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
Measure Description
Time Frame
Lumbar lordosis angle (LL)
Time Frame: 6 months
Lumbar lordosis angle
6 months
Lumbar spinal area
Time Frame: 6 months
measured by CT(GE light speed QX/i)
6 months
knee extension angle
Time Frame: 6 months
The angle of knee extension the angle between the line connecting the greater trochanter of the femur and the lateral condyle of the femur and the line connecting the lateral condyle of the knee and the lateral condyle of the ankle.
6 months
