Connective Tissue of Pectoralis Major Muscle: Anatomical Study

The delto-pectoral tendon (DPT) is a new tendon recently identified. It completes the insertion of the pectoralis major and perfectly explains the different injuries encountered.

The objective of this observational study is to visualize this new tendon, the DPT, using ultrasound, to measure it, to characterize its role in the overall architecture of the pectoralis major muscle and to analyze its relationship with its main tendon and the anterior and posterior laminae.

Other

Through systematic ultrasound visualization of the pectoralis major muscle, we seek to directly visualize and characterize the different intra- and extra-muscular connective structures of the muscle - Delto Pectoral Tendon (DPT) , Distal Pectoralis Major Tendon (PMT), Anterior Deltoid Tendon (ADT), Anterior Pretendinous Lamina of the Pectoralis Major (ALPM), Posterior Pretendinous Lamina of the Pectoralis Major (PLPM) and Deep Fascia of the Pectoral Major (DFPM) - constituting its connective skeleton, with particular attention to its distal portion near the humerus and on the search for this DPT tendon.

Other names: Shoulder ultrasound with focus on pectoralis major muscle connective skeleton and distal tendon

  2. Measurement of ADT by ultrasonography (height, length and thickness in mm)

    Time frame: Day 1

  3. Measurement of PMT by ultrasonography (height, length and thickness in mm)

    Time frame: Day 1

  4. Measurement of the distances in mm between the PMT humeral insertion and the different connective structures: ADT, DPT, ALPM, PLPM and DFPM

    Time frame: Day 1

  5. Ultrasound visualization of the clavicular and sternal portions of the pectoralis major.
