Table Of Ossification Of The Bones Of The Shoulder

Bone	Centres	Time of appearance of centre	Union of primary and secondary centres; remarks.
Clavicle	Diaphysis	6th week	There are two centres in the shaft, a medial and a lateral. These blend on the 45th day (Mall). Shaft and epiphysis unite between the 20th and 25th years.
	Sternal epiphysis	18th to 20th year
Scapula	Primary centres:		The chief centre appears near the lateral angle. The subcoracoid centre appears at the base of the coracoid process and also gives rise to a part of the superior margin of the glenoid fossa. The coracoid process joins the body about the age of puberty. The acromial epiphysis centres (two or three in number) fuse with one another soon after their appearance and with the spine between the 22nd and 25th years (Quain); 20th year (Wilms). The subcoracoid and the epiphysis of the coracoid process, the glenoid fossa, the inferior angle, and the vertebral margin join between the 18th and 24th years in the order mentioned (Sappey).
	1. That of the body, the spine, and the base of the glenoid cavity.	8th week (Mall) 1
	2. Goraooid process	1st year
	3. Subcoracoid	10th to 12th year
	Epiphyses:
	Acromial epiphyses	15th to 18th year
	Epiphysis of the inferior angle.	16 to 18th year
	Epiphyses of the vertebral border.	18th to 20th year
	Epiphyses of upper surface of coracoid.	16th to 18th year.
	Epiphysis of surface of glenoid fossa.	16th to 18th year.
