The Cross-sectional Area of the Long Head of the Biceps Tendon and the Rotator Cuff Tear Position

July 27, 2022 updated by: RenJi Hospital

The Correlation Between the Cross-sectional Area of the Long Head of the Biceps Tendon and the Tear Position in Patients With Rotator Cuff Tears

The main aim and scope of this study is making measurement and comparison of the cross-sectional area of the long head of the biceps tendon(LHBT) in the patients suffered form rotator cuff tear with different tear positions, and making observation and comparison of the impairment type of the LHBT in the patients suffered from rotator cuff tear with different tear positions. The results may identify the influence of the tear position on the LHBT.

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

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.

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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Anterior tear group
The rotator cuff was divided into three parts according to the arthroscopic discovery: (1) the anterior part which contained the subsacpularis and one third of the suprascapularis forward; (2) the middle part which contained the two thirds of the suprascapularis backward and one third of the subscapularis forward; (3) the posterior part which contained two thirds of subscapularis backward and teres minor. The patients with rotator cuff tear at the anterior part were categorized in the anterior tear group.
Procedure: Arthroscopic rotator cuff repair
The rotator cuff tears were repaired under arthroscopy. A subacromial decompression was performed in all patients. Then the long head of the biceps with severe lesions were treated by tenotomy while the others were reserved according to the surgeon's judgment during the surgery.
Experimental: Middle tear group
The rotator cuff was divided into three parts according to the arthroscopic discovery: (1) the anterior part which contained the subsacpularis and one third of the suprascapularis forward; (2) the middle part which contained the two thirds of the suprascapularis backward and one third of the subscapularis forward; (3) the posterior part which contained two thirds of subscapularis backward and teres minor. The patients with rotator cuff tear at the middle part were categorized in the middle tear group.

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
Pre-operative measurement of the cross-sectional area of the long head of bicep tendon
Time Frame: Pre-operative
According to the pre-operative MRI scan, two sites of the long head of biceps tendon were measured by the Image-Pro Plus 6.0 software. One was the plane that passed the center of the glenoid cavity, the other one was the plane that passed the distal border of the glenoid cavity. The contour of the long head of biceps tendon was traced and the area was calculated by the software according to the MRI's scale.
Pre-operative

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
Post-operative measurement of the cross-sectional area of the long head of bicep
Time Frame: 2 months after the surgery
According to the MRI scan 2 months after the surgery, two sites of the long head of biceps tendon were measured by the Image-Pro Plus 6.0 software. One was the plane that passed the center of the glenoid cavity, the other one was the plane that passed the distal border of the glenoid cavity. The contour of the long head of biceps tendon was traced and the area was calculated by the software according to the MRI's scale.
