Bone - Post ICA Flashcards
What are the joints related to the clavicle?
Sternoclavicular joint.
Acromioclavicular joint.
Which end of clavicle is convex forwards?
Medial 2/3rd (convex forwards).
Lateral 1/3rd (concave).
What does the lateral end of clavicle articulate with?
Scapula - Acromion process of scapula.
What are the parts of scapula?
2 surfaces.
Acromion process.
Coracoid process.
Spinous process.
What notch does the superior border of scapula have?
Suprascapular notch.
What does the spinous process do?
Divide the supraspinous fossa and infraspinous fossa.
What does the lateral angle of scapula contain?
Glenoid fossa - articulates with head of humerus. Shoulder joint.
What are the tubercles that are related to the glenoid?
Supraglenoid.
Infraglenoid.
Which ligament supports shoulder joint?
Coracoacromion ligament.
What are the parts of humerus.
Upper end - Head: Anatomical and surgical neck. Greater and lesser tubercles. Intertubercular sulcus.
Shaft: Medial and lateral supracondylar ridges. Deltoid tuberosity. Spiral Groove.
Lower end: Capitulum. Trochlea.
What is behind the surgical neck of humerus?
Axillary nerve.
What happens if there is a fracture of surgical neck?
Damage to axillary nerve and artery
What lies in the spiral groove?
Radial nerve.
What is a benefit of having a carrying angle?
Creates a angle that is helpful in carrying stuff. Created because of trochlea.
What are the nerves related to humerus?
Axillary - surgical neck.
Radial - spiral groove
Ulnar - medial epicondyle.
Proximal end of ulna
Hook like process - olecranon process an coronoid process.
Trochlear notch - accommodates trochlea of humerus.
Ulnar tuberosity - roughened area.
Styloid process.
Radius
Disk like head - articulate capitulum
Neck of radius.
Radial tuberosity.
Lower end - Ulnar notch on medial surface.
Inferior surface - scaphoid and lunate.
Lateral surface - Radial styloid.
What action does the radioulnar joint provide?
Pronation and supination.
What is cleidocranial dysplasia?
When the patient has no clavicle.
If there is a dislocation at the elbow, which nerves can be stretched?
Ulnar and median.
