Fig. 4From: Anteroinferior bundle of the acromioclavicular ligament plays a substantial role in the joint function during shoulder elevation and horizontal adduction: a finite element modelSchematic representation of the footprint area of the acromioclavicular ligament in a right shoulder. The registration nodes are arranged and paired according to the clock model [15]. The green area represents the bone attachment of the AC ligament. A Anterior view of the ACJ. B Superoposterior view of the ACJ. C Posterior view of the ACJ. D Parasagittal view of the clavicle showing the PSB, AIB, and the clock model.
