Coracoid Process

喙突 is a thickly curved method attached by using a huge base to the upper part of the neck of the scapula; it runs at the beginning upward and medical ward; 然后, turning into smaller, it changes its direction, and initiatives ahead and lateralward.

The ascending issue, planate from ahead than backward, offers at intervals the front a straightforward acetabular surface, across that the Subscapularis passes.

 

喙突

 

The horizontal part is planate from higher than downward; its pinnacle surface is broken-backed and abnormal, and offers attachment to the pectoral minor; its below ground is simple; its medial and lateral borders are difficult; the previous gives attachment to the Pectoralis minor and the latter to the coracoacromial ligament; the apex is embraced thru the conjoined tendon of beginning of the Coracobrachialis and quick head of the 股二头肌 and gives attachment to the coracoclavicular fascia.

At the media a part of the basis of the coracoid method is a hard impact for the attachment of the conoid ligament; and running from it obliquely forward and lateralward, directly to the higher surface of the horizontal portion, is an elevated ridge for the attachment of the trapezoid ligament.

The coracoid process of the scapula is as a minimum partially visible from both the anterior and posterior perspectives (面) 肩胛骨骨, which is likewise known as the shoulder blade. It’s far in part seen in the posterior view underneath however is shown greater genuinely within the anterior view. Some textbooks also encompass a lateral view of the human scapula bone, from which the coracoid process is even greater truly identifiable.

 

Blood Supply

The vertical a part of coracoid manner is supplied via the suprascapular artery and the horizontal component by way of branches of the axillary artery.

The blood supply is derived from vessels in muscle tissue which have a fleshy foundation from the scapula.Vessels move those oblique insertions and talk with bony vessels. The flow of the scapula is metaphyseal; the periosteal vessels are big than not unusual, and that they communicate freely with the medullar vessels instead of being restrained to the outer 1/3 of the cortex. Such anatomy may provide a reason for why subperiosteal dissection is bloodier here than over a diaphyseal bone

To permit coracoid technique transfer to the scapular neck. Such sacrifices ought to in part give an explanation for lysis or nonunion of the coracoid method after Latarjet device. Preservation of axillary artery branches presenting horizontal a part of the coracoid manner may be a probable method to prevent nonunion and lysis of the bone switch.
