3D Printed Upper Limb Skeleton and Ligaments

3D Printed Upper Limb Skeleton and Ligaments This 3D printed specimen presents the entire upper limb skeleton and ligaments from the pectoral girdle to the hand. In the pectoral girdle, the ligaments spanning the clavicle and scapula (acromioclavicular, coracoclavicular, coracoacromial) as well as the superior transverse scapular ligament spanning the suprascapular notch, are visible. A small portion of the supraspinatus muscle belly and tendon are preserved to demonstrate the passage of the muscle deep to the coracoacromial ligament, which is a very clinically relevant area of anatomy. The tendon of the subscapularis muscle has been reflected slightly to expose the anterior aspect of the glenohumeral joint capsule, and the tendon of the long head of triceps brachii, teres major, and latissimus dorsi are preserved surrounding the capsule and proximal humerus. The tendon of the long head of biceps brachii is visible within the intertubercular groove, and exposed within the su
