STERNOCLAVICULAR JOINT
the only articulation between upper limb & axial skeleton
Articulation between Sternum &clavicle
Saddle type functions as a ball-and-socket joint
Articular disc
Sternal end of clavicle v.s. Manubrium & 1st costal cartilage
3
LIGAMENTS OF THE
STERNOCLAVICULAR JOINT
1. Anterior and posterior sternoclavicular ligaments
2. Interclavicular ligament
3. Costoclavicular ligament
4
MOVEMENTS OF THE
STERNOCLAVICULAR JOINT
Strong but mobile
Raising the clavicle (60°) during full elevation of the limb
Once elevation is completed via flexion; rotation of the clavicle
around itslongitudinal axis
Anterior and posterior movements of the clavicle
5
ACROMIOCLAVICULAR JOINT
2-3 cm from the “point” of the shoulder formed by the lateral part of the acromion
Articulation between Acromion of scapulae & clavicle
Plane type
Articular disc
Acromial end of clavicle v.s. Acromion of scapula
6
LIGAMENTS OF THE
ACROMIOCLAVICULAR JOINT
Intrinsic ligament
Acromioclavicular ligament
Extrinsic ligament
Coracoclavicular ligament
conoid ligament (medial)
trapezoid ligament (lateral)
7
MOVEMENTS OF THE
ACROMIOCLAVICULAR JOINT
Acromion rotates on the acromial end of the clavicle.
associated with motion @ physiological scapulothoracic joint
8
GLENOHUMERAL (SHOULDER) JOINT
more freedom of movement than any other joint in the body
Articulation between humeral head v.s. glenoid cavity of the scapula
Ball-and-socket type
Glenoid labrum (L., lip)

LIGAMENTS OF THE
GLENOHUMERAL (SHOULDER) JOINT
1. Glenohumeral ligaments
2. Coracohumeral ligament
3. Transverse humeral ligament
4. Joint
Coracoacromial
stability ligament
10
MOVEMENTS OF THE
GLENOHUMERAL (SHOULDER) JOINT
Flexion & extension of the humerus
Abduction & adduction of the humerus
Medial & lateral rotation of the humerus
Circumduction
11
BURSAE AROUND THE
GLENOHUMERAL (SHOULDER) JOINT
12
ELBOW JOINT
2-3 cm inferior to the epicondyles of the humerus
Articulation between Humerus, ulna and radius
Hinge type
Trochlea of humerus v.s. Trochlear notch of ulna
Capitilum of humerus v.s. Head of radius
13
LIGAMENTS OF THE ELBOW JOINT
Medial (ulnar) and lateral (radial) collateral ligaments
14
MOVEMENTS OF THE ELBOW JOINT
Flexion and extension occur at the elbow joint.
The long axis of the fully extended ulna
makes an angle with the long axis of the humerus.
forearm angles away from the body when something is carried.
more pronounced in women than in men
15
BURSAE AROUND THE ELBOW JOINT
16
PROXIMAL (SUPERIOR) RADIO-ULNAR JOINT
Articulation between Radius and ulna proximally
Pivot type
Head of radius v.s. Radial notch of ulna
Anular ligament
MORE IMAGES

17
DISTAL (INFERIOR) RADIO-ULNAR JOINT
Articulation between Radius and ulna distally
Pivot type
Articular disc
head of ulna v.s. ulnar notch of radius
Anterior and posterior ligaments
Supination & pronation
Radius moves around relatively fixed
distal end of ulna.
18
WRIST (RADIOCAPRAL) JOINT
Articulation between Radius and proximal row of carpal bones
Condyloid (ellipsoid) type
Articular disc
Distal end of the radius ,disc of the distal radio-ulnar joint
v.s.
proximal row of carpal bones, except for the pisiform
19
LIGAMENTS OF THE
WRIST JOINT
1. Dorsal and palmar radiocarpal ligaments
2. Ulnar collateral ligament
3. Radial collateral ligament
20
MOVEMENTS OF THE WRIST JOINT
Proximal
&
Distal
Radioulnar
joints
Most adduction @ wrist joint
Abduction from the neutral position
21
occurs @ midcarpal joint.
INTERCARPAL JOINTS
Joints between carpal bones of the proximal row
Joints between carpal bones of the distal row
Midcarpal joint between proximal &distal rows of carpal bones
Anterior, posterior, and interosseousligaments
22
CARPOMETACARPAL &
INTERMETACARPAL JOINTS
carpometacarpal joint of the
thumb
between trapezium & base of 1st metacarpal
