Summary
30 MRI investigations of shoulders and 20 dissections of non embalmed cadaveric shoulders allowed us to demonstrate a particular organization of the supraspinatus muscle. In the anterior part of the muscle is an important fibrous frame with obliquely inserted muscle fibers. This organization suggests that this part of the supraspinatus muscle works as a “contractile tendon”.
Résumé
30 dossiers d'IRM d'épaule et 20 dissections sur sujets non embaumés ont permis d'établir l'existence d'une structure fibreuse importante parcourant le tiers externe de la portion antérieure du muscle supra-épineux. Une telle organisation suggère un rôle de “ligament actif” pour cette portion du muscle.
