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

Not Applicable

• Conditions: Rotator Cuff Tears
• Interventions: Procedure: Arthroscopic rotator cuff repair

• Registration Number: NCT05477771
• Lead Sponsor: RenJi Hospital

Brief Summary

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.

Arm && Interventions

Group	Intervention	Description
Anterior tear group	Arthroscopic rotator cuff repair	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.
Middle tear group	Arthroscopic rotator cuff repair	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.
Posterior tear group	Arthroscopic rotator cuff repair	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 posterior part were categorized in the posterior tear group.

Primary Outcome Measures

Name	Time	Method
Pre-operative measurement of the cross-sectional area of the long head of bicep tendon	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.

Secondary Outcome Measures

Name	Time	Method
Post-operative measurement of the cross-sectional area of the long head of bicep	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.
