Q

What are the three types of the fracture of lateral third of clavicle

A

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

18
Q

What is humerus

A

Is the longest and largest bone of the upper limb which extends from shoulder to elbow

19
Q

Humerus articulated with

A

Scapula at the glenohumeral joint and radius and ulna at the elbow joint

20
Q

What does it consist of

A

Proximal end
Shaft

Distal end

21
Q

Anterior view has

A

Greater and Lester tuberosity
Radial and coronoid fossa
Medial and lateral epicondyle
Capitulum and trochlea
Deltoid tuberosity
Bicipitak groove

22
Q

Explain greater and lesser tuberosity

A

Greater is consist of three smooth and flat impression at the posterosuperior aspect for the attachment of roraroe cuff muscles
Lessrer it provides attachment for tge subscapularis

23
Q

Explain radial and coronoid fossa

A

Radial. Named as the margin of the head of the radius lodges there full flexion
Coronoid. During flexion of the elbow it’d lodges into the coronoid fossa

24
Q

Explain lateral and medial epicondyle

A

Lateral. The Common extensor origin for muscle of the posterior forearm
Medial. The common flexor origin for muscle of the anterior forearm

25
Q

Explain capitulum and trochlea

A

Capitulum. Articulate with the head of radius
Trochlea . Articulate with trochlear notch of the ulna

26
Q

Explain deltoid tuberosity and bicipital groove

A

Deltoid. Roughened v shaped region located laterally on the mid-shaft of the humerus’s
Bicipital groove. Narrow groove located btw greater and lesser tubercles of the humerus

27
Q

Posterior view of humerus

A

Head of the humerus: it articulate with the glenoid fossa of the scapula
Anatomical neck: the site of attachment of the joint capsule
Surgical neck: found inferior to the head of humerus
Radial groove: radial deep brachial artery
Olecranon fossa: is deep hollowed area on the posterior surface, superior to the trochlea
Groove for ulnar nerve: where the ulnar nerve runs

28
Q

Radius

A

Is lateral and shorter of the two forearm bones and is long bone in forearm

29
Q

What is the proximal end of the radius and distal end

A

Proximal: has head which articulates with both the distal humerus and the proximal ulna
Distal: articulate with the head of the ulna and carpal bone at wrist

30
Q

Articular circumference

A

Is place within the radial notch of the ulna

31
Q

Ulnar notch

A

Articulate with the head of ulna

32
Q

Explain the head of radius and neck of radius

A

Head: articulates with the Capitulum of the humerus as part of the elbow joint
Neck: lie btw the radial head and radial tuberosity

33
Q

Radial tuberosity

A

Located on the middle side of proximal radius
The place of the attachment of the biceps brachii muscle

34
Q

Radial styloid process

A

Is larger than ulnar styloid process and extend farther dismally
Because of the the rand of wrist abduction (radial deviations) is lees the wrist abduction range of ( ulnar deviation)

35
Q

Carpal articular surface

A

Articulations face for carpal bone . Scaphoid laterally and lunate medially

36
Q

What is ulna

A

Is the medial bone of the forearm and the longer of the two parallel forearm bones

37
Q

Ulna proximal articulate where

A

Proximal articulate with the humerus proximally and the head if radius laterally

38
Q

Olceranon

A

The triceps brachii muscle attaches to its superior surface

39
Q

Radial and trochlea notch explanations

A

Radial : articulate with the circumference of the radial head
Trochlea: formed by olcranon and coronoid process

40
Q

Coronoid process and ulnar styloid process

A

Coronoid: is accommodated by the coronoid fossa in the anterior aspect of the distal humerus during flexsion
Styloid process: projecting from the posterior side of the ulnar head

41
Q

Ulnar tuberosity and head of ulna

A

Tuberosity: it’s where brachialis muscle attaches
Head of ulna: articulate with ulnar notch of distal radius

42
Q

Manus or hand bone

A

Provide support and flexibility to the soft tissue

43
Q

What is the distal and proximal raw of manus bone

A

Proximal: scaphoid, lunate triquertrum, pisiform
Distal: traperzium, trapezoid, capitate, hamate
