If you are interested in uploading your CT scans and converting these to 3D-printable STL format, the democratiz3D® Quick Start Guide will help you to quickly get up and running. Register with embodi3D® today! Technologies like these were recently featured in the journal Société Internationale de Chirurgie Orthopédique et de Traumatologie (SICOT), where models of a 3D scapula, humerus, and soft tissues are being used in preoperative planning. It's absolutely free to sign up and you can take advantage of many of the features found on the embodi3D® website, including standard resolution democratiz3D® conversions. In this week's embodi3D® Top Ten, we are bringing you some of the best 3D scapula, clavicle, and humerus models which comprise the majority of the human shoulder joint.īefore you dive into this week's Top 10 and start printing your own 3D anatomical models, you must first register with embodi3D®. But, these features also make the shoulder prone to overuse injuries, subluxation, dislocation, and ligament tears. In fact, the shoulder has the most extended pivot range of any joint within the body. Your glenohumearal joint (shoulder) is a ball-and-socket joint that is able to move in so many positions due to the relatively small size of the glenoid fossa, as well as the laxity ('wiggle room') of the joint capsule.

These include humerus (bone in the upper arm), scapula (shoulder blade), and the clavicle, which we commonly refer to as the 'collarbone.' Bones of the shoulder work together with the transverse humeral ligament, synovial membrane of the bicep, bursa sac, and the superior transverse ligament to perform a complex range of motions.

Shoulders are comprised of three main bones.
