Few reports of latissimus dorsi tendon avulsion, with or without teres major
involvement, exist, highlighting the rare nature of this injury.
The MRI showed an isolated avulsion of the teres major
Various muscle transfers such as trapezius, pectoralis major and teres major
, latissimus dorsi, combined biceps and triceps, gracilis, and combined muscle transfers have been used in the secondary reconstruction of the shoulder.
First, we concentrate on the PHCA passing under the fused tendons of the teres major
(musculus teres major
, TM) and the latissimus dorsi (musculus latissimus dorsi, LD).
It can also be done through the posterior approach by releasing the muscle on the anterior surface of the scapula (5, 11-13) and releasing the teres major
and the pectoral major.
Thus teres major
, latissmus dorsi and pectoral muscles are never involved and the shoulder block will cover most or all of the surgical pain.
* Teres major
-- adducts and laterally rotates the arm.
Other muscles like the teres major
, infraspinatus, anterior and posterior latissimus dorsi, pectoralis major and the anterior and posterior deltoids are called upon to support the failing muscles.
The boundaries of the triangular space (above by the teres minor, below by the teres major
and laterally by the long head of the triceps brachii) of the upper limb are well known.
Sometimes the teres major
tendon is transferred in addition to the latissimus dorsi tendon (LDT) in order to obtain better external rotation of the shoulder [4, 5].
The computer model included seven muscles that were simulated as three lines from origin to insertion: anterior deltoid, middle deltoid, posterior deltoid, subscapularis, infraspinatus, teres major
, and teres minor.
