About this 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
UltrasoundOther
Also called Shoulder ultrasound with focus on pectoralis major muscle connective skeleton and distal tendon
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.

Questions about this trial
What is this clinical trial studying?
An observational study of Tendon Injury - Upper Limb, run by CMC Ambroise Paré at 1 site in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 8 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Ultrasound visualization of Delto Pectoral Tendon (time frame: Day 1). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06441903, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Apr 2026.
