JOINTS OF THE UPPER LIMB Victoria Gugenheim Body Art Kaan Ycel M.D., Ph.D. 03.March.2014 Monday JOINTS OF THE UPPER LIMB
Acromioclavicular joint & Sternoclavicular joint Glenohumeral (Shoulder) joint Elbow joint Proximal (Superior) and Distal (Inferior) radio-ulnar joints Radiocarpal (Wrist) joint Intercarpal joints Carpometacarpal and intermetacarpal Interphalangeal 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 LIGAMENTS OF THE STERNOCLAVICULAR JOINT
Anterior and posterior sternoclavicular ligaments Interclavicular ligament Costoclavicular ligament STERNOCLAVICULAR JOINT
MOVEMENTS OF THE STERNOCLAVICULAR JOINT Strong but mobile Raisingthe clavicle (60) during full elevation of the limb Once elevation is completed via flexion; rotation of the clavicle around its longitudinal axis Anterior and posterior movements of the clavicle 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 LIGAMENTS OF THE ACROMIOCLAVICULAR JOINT
Intrinsic ligament Acromioclavicular ligament Extrinsic ligament Coracoclavicular ligament conoid ligament (medial) trapezoid ligament (lateral) MOVEMENTS OF THE ACROMIOCLAVICULAR JOINT
Acromion rotates on the acromial end of the clavicle. associated with physiological scapulothoracic joint 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) MORE IMAGES GLENOHUMERAL (SHOULDER) JOINT
LIGAMENTS OF THE GLENOHUMERAL (SHOULDER) JOINT Glenohumeral ligaments Coracohumeral ligament Transverse humeral ligament 4. Coracoacromial ligament Joint stability coraco-acromial arch GLENOHUMERAL (SHOULDER) JOINT
MOVEMENTS OF THE GLENOHUMERAL (SHOULDER) JOINT Flexion & extension of the humerus Abduction & adduction of the humerus Medial & lateral rotation of the humerus Circumduction GLENOHUMERAL (SHOULDER) JOINT
BURSAE AROUND THE GLENOHUMERAL (SHOULDER) JOINT 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 LIGAMENTS OF THE ELBOW JOINT
Medial (ulnar) and lateral (radial) collateral ligaments 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 BURSAE AROUND THE ELBOW JOINT Head of radius v.s. Radial notch of ulna
PROXIMAL (SUPERIOR)RADIO-ULNAR JOINT Articulation between Radius and ulna proximally Pivot type Head of radius v.s. Radial notch of ulna Anular ligament Supination & pronation MORE IMAGES head of ulna v.s. ulnar notch of radius
DISTAL (INFERIOR)RADIO-ULNAR JOINT Articulation between Radius and ulna distally Pivot type Articular disc head of ulna v.s. ulnar notchof radius Anterior and posterior ligaments Supination & pronation Radius moves around relatively fixed distal end of ulna. 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 LIGAMENTS OF THE WRIST JOINT Dorsal and palmar radiocarpal ligaments Ulnar collateral ligament Radial collateral ligament MOVEMENTS OF THE WRIST JOINT
Proximal & Distal Radioulnar joints Most wrist joint Abduction from the neutral position midcarpal joint. Flexion of the hand> Extension of the hand Adduction of the hand > Abduction of the hand Anterior, posterior, and interosseous ligaments
INTERCARPAL JOINTS Plane type 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 interosseous ligaments CARPOMETACARPAL & INTERMETACARPAL JOINTS
carpometacarpal joint of the thumb between trapezium & base of 1st metacarpal INTERPHALANGEAL JOINTS
METACARPOPHALANGEAL & INTERPHALANGEAL JOINTS MORE IMAGES Metacarpophalangeal joints condyloidtype biaxial plane : flexion-extension and adduction-abduction Interphalangeal joints hinge type uniaxial flexion-extension only
