Bone Of The Upper Limb Flashcards
Upper limb is consist of
- Pectoral girdle: clavicle and scapula
- Free part ( pars libera membri superioris) : A humerus, F radius, ulna, H carpal bone, metacarpal bone, phalange
What is clavicle
Is elongated S shape bone which is contoured by many muscles which attach to if
clavicle extend btw
Btw the manubrium of the sternum and the acromion of the scapula
What is the most fracture bone in the upper limb
Clavicle
What are the three main functions of clavicle
Attaches
Protect
Transmit
What does it call the two end of clavicle
Acromial
Stern Al
What are the two fancies of the acromial and sternal
Facies articulatris sternalis
Facies articularis acromialis
Is quite rough and has many prominent lone indicating site where the muscle and ligaments may attach to the bone
Inferior surface of clavicle
- Attachment point of trapezoid ligaments
- For subclavius muscles
- The site where the conoid ligament attaches
- Impression of
- Trapezoid line
2 subclavian groove - Conoid tubercle
- For costalclavicular ligaments
Where is mist common fracture in the clavicle
The middle third of clavicle
Which muscle get damage
Sterbocleidomastoid muscle
What are the three types of the fracture of lateral third of clavicle
Fracture with no disruption of ligament and therefore no displacement
Fracture with tear of Cora coracoclavicura ligament and upward displacement of medial fragments
Fracture through acromioclavicular joints no displacement and it may course painful osteoarthritis requiring resection arthoplasty
Posterior surface of scapula
Articulate with humerus at the glenohumeral join and clavicle at the acromiiclvicular joints
Where the scapula located
At the back of the trunk and resides over the posterior surface of rib 2 to 7
Explain the attachment of 1. Glenoid cavity 2. Infraglenoid tubercle 3. Supraglenoid tubercle
1 part of scapula articulation with head of humerus
2 the place at attachment of the long head of the triceps brachii
3 the place of attachment of long head of the biceps brachii
Suprascpular notch
Is converted into foremen by transverse scapular ligament and its serves as passage for suprascapularnerve and suprascapular artery over the ligaments
Coracoid process
Allow the attachment of various muscles and ligaments
