BioMed Central | Full text | Does preoperative abduction value affect functional outcome of combined muscle transfer ... (3717 words)
Subscapularis muscle was released from the anterior surface of the scapula subperiostally from a small incision at the lateral side of the scapula carefuly, in order to prevent injury to the pedicle of lattisimus dorsi and teres major muscles (Figure 6).
The importance of transferring the teres major and latissimus dorsi as one conjoined tendon and anchoring into the posterior aspect of the greater tuberosity at the insertion of the infraspinatus similar to Hoffer method is augmentation of the weakened infraspinatus.
In that condition, the levator scapulae muscle is utilised as an intrinsic stabilizer of glenohumeral joint and trapezius muscle is used as a prime mover for shoulder abduction with or without latissimus dorsi and teres major transfers [9].
