About

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.

38 participants in 3 patient groups

Anterior tear group

Experimental group

Description:

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.

Treatment:

Procedure: Arthroscopic rotator cuff repair

Middle tear group

Experimental group

Description:

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

Experimental group

Description:

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.
