Teres major muscle - insertion footprint

Teres major muscle – insertion footprint

Teres major muscle (TM) and latissimus dorsi muscle (LD) are frequently used in muscle transfers around the shoulder girdle. Some authors have suggested harvesting techniques in which the muscle is detached in continuity with a bone segment. Information on the bony attachment footprint of these muscles is lacking. The purpose of this study was to investigate the region of attachment of the TM t...

Variant insertion of the teres major muscle

The teres major (TerMa) muscle has a clinical significance for tendon transfer procedures in patients with massive rotator cuff tears. Individually, it originates from the dorsum of the inferior angle of scapula and inserts into the medial lip of bicepital groove of the humerus. Functionally, TerMa in cooperation with latissimus dorsi (LD) adducts arm, medially rotates arm, and assists in arm e...

The function of the teres major muscle: an electromyographic study.

Imaging features of desmoid-type fibromatosis in the teres major muscle.

Desmoid-type fibromatosis is a locally aggressive fibroblastic neoplasm with a tendency for local recurrence, despite adequate surgical resection. Its clinical presentation, biological behavior, and natural history can vary considerably. We present a unique case of desmoid-type fibromatosis arising in the left teres major muscle of a 62-year-old female. Physical examination showed a 7-cm, elast...

Teres major muscle activation relates to clinical outcome in tendon transfer surgery.

BACKGROUND In massive rotator cuff tears a teres major (TMj) tendon transfer to the insertion of the supraspinatus (SSp) reverses its adduction moment arm into abduction which is supposed to be an adequate salvage procedure. Analysis of muscle function to find biomechanical ground of such success is scarce. METHODS We compared pre- and postoperative clinical outcome of TMj transfer, i.e. Rang...
