-
Bones of the Schoulder Girdle
Scapula, clavicle and sternum
-
Clavicle
- Last bone to ossify (21 years)
- attaches to sternum and Scapula
- Transmits shocks from upper limb to the axial skeleton
- medial 2/3 or convex anteriorly
-
how does clavical differ from other long bones
- ossifies with cartilage
- no marrow cavity
- no medullary cavity
- spongy bone shell of compact bone`
-
ligaments attached to Clavical
- sternoclavicular
- interclavicular
- costoclavicular
- coracoclavicular
- acromioclavicular
-
Muscles attached to Clavical
- Deltoid
- trapezius
- pectoralis major
- sternocleidomastoid
- subclavius
-
fracturing of clavical
- common site is junction between two curves
- lateral fragment displaced downward
- subclavian vien and artery can lie close in relation to fracture site and be damaged
-
Cleidocranial dysostosis
- condition in which clavicals are congenitally absent , or imperfectly developed.
- shoulder droop, and can be approximated anteriorly in front of chest
-
Scapula
- between 2nd and 7th rib
- triangular flat bone
-
Articulations of Scapula
- Acromioclavicular (AC)
- Coracoclavicular
- Glenohumeral (shoulder)
-
Ligaments attached to Scapula
- Acromioclavicular
- Coracoclavicular
- glenohumeral
- superior transverse scapular
- spinoglenoid (inferior transverse scapular)
- Costocoracoid (part of the clavipectoral fascia)
-
Scapula Bursae
- subscapular- communicates with shoulder joint
- subacromial- communicate with subdeltoid bursa
-
Glenoidal Labrum
a fibrocartilaginous rim attached around the margin of the glenoid cavity. it deepends the articular cavity, and protects the edge of the bone
-
winged Scapula
- scapula sticks out back
- caused by damage to the long thoracic nerve by weakness in in the serratus anterior muscle
-
Bones thsat make up upper limb
- Humerus
- Ulna
- Radius
- Carpal
- Metacarpals
- Phalanges
-
Parts of the Humerus
- Upper (Proxmal) end
- Shaft
- Lower (distal) end
-
Anatomical Neck
- slight constriction at margin of articular surface and head
- attaches to capsular ligament of shoulder
-
Surgical Neck
- it is constricted at the upper end of shaft just below tubercles
- common site of fracture
- axillary nerve and Posterior Circumflex Humeral Artery lies medial
-
intertubercular sulcus contains
- Long head of the biceps tendon
- synovial sheath of bicep
- Ascending branch od anterior circumflex humeral artery
-
Muscles attached to greater tuberosity
- supraspinatus
- infraspinatus
- teres minor
- transverse ligament
-
Muscles attached to lesser tubercle
- subscapularis
- transverse ligament
-
Muscles in Intertubercular Sulcus
- Pectoralis Major
- Teres major
- Latissimus dorsi
-
Muscle attachments to the anterior surface of Humerous
- Caracobrachialis
- Deltoid
- Brachialis
-
Attachment to the posterior surface
- Lateral head of triceps brachii
- Medial head of triceps brachii
- long head of triceps brachii
-
Surgical Neck fracture (clinical)
Axiallary Nerve
-
Middle shaft fracture (clinical)
radial nerve (saturday Night[cruthch] palsy)
-
Supracondyla (distal) fracture (clinical)
Median Nerve
-
Medial epicondyle (clinical)
Ulnar nerve
-
Avulsion fracture fo greater tubercle of humerus (clinical)
Medial rotation
-
Neurovascular Bundles that associate with the upper limb
- Axillary nerve / posterior circumflexhumeral artery
- Radial Nerve & profunda brachii
- Median Nerve and brachial artery
- ulnar nerve and superior ulnar collateral artery
- Musculocutanous
-
3 parts of shoulder joint
-
what joints facilitate shoulder movement
- Acromioclavicular (AC) Joint
- glenohumeral (shoulder) Joint
-
what structure keeps the ball and socket joint together, provides mobility, and strength
rotator cuff
-
2 slimy sac-like structures that help provide smooth gliding between bone, muscle, and tendon
Bursae
-
why is the shoulder subject to easy injury?
ball is too large for socket
