JOINTS OF THE UPPER LIMB Victoria Gugenheim Body Art Kaan Yücel M.D., Ph.D. • 06.January.2014 Monday
JOINTS OF THE UPPER LIMB Joints of the pectoral girdle 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
JOINTS OF THE UPPER LIMB Joints of the pectoral girdle 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
STERNOCLAVICULAR JOINT the only articulation between upper limb & axial skeleton Articulation between Sternum & clavicle Saddle typefunctions as a ball-and-socket joint Articulardisc Sternalend of clavicle v.s. Manubrium& 1st costal cartilage
LIGAMENTS OF THE STERNOCLAVICULAR JOINT Anterior and posterior sternoclavicular ligaments Interclavicular ligament Costoclavicular ligament
MOVEMENTS OF THE STERNOCLAVICULAR JOINT Strong but mobile Raising theclavicle(60°) duringfullelevation of thelimb Onceelevation is completedviaflexion; rotation of theclavicle arounditslongitudinalaxis 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 Articulardisc Acromialend of clavicle v.s. Acromionof scapula
LIGAMENTS OF THE ACROMIOCLAVICULAR JOINT Intrinsic ligament Acromioclavicularligament 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 motion @ physiological scapulothoracicjoint
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 Glenoidlabrum(L., lip) • MORE IMAGES • 114-122
LIGAMENTS OF THE GLENOHUMERAL (SHOULDER) JOINT Glenohumeralligaments Coracohumeral ligament Transverse humeral ligament 4. Coracoacromialligament Jointstability coraco-acromialarch
MOVEMENTS OF THE GLENOHUMERAL (SHOULDER) JOINT Flexion & extensionof the humerus Abduction & adductionof the humerus Medial &lateral rotation of the humerus Circumduction
BURSAE AROUND THE GLENOHUMERAL (SHOULDER) JOINT
ELBOW JOINT 2-3 cm inferior to the epicondyles of the humerus Articulation betweenHumerus, ulna and radius Hinge type Trochleaof humerusv.s. Trochlearnotch of ulna Capitilum of humerusv.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
PROXIMAL (SUPERIOR) RADIO-ULNAR JOINT Articulation between Radius and ulna proximally Pivot type Headof radius v.s. Radialnotch ofulna Anularligament Supination & pronation • MORE IMAGES • 133 -134
DISTAL (INFERIOR) RADIO-ULNAR JOINT Articulation between Radius and ulna distally Pivot type Articular disc headof ulna v.s. ulnar notch of radius Anterior and posterior ligaments • Supination & pronation Radiusmoves around relatively fixed distal end of ulna.
WRIST (RADIOCAPRAL) JOINT Articulation between Radius and proximalrow of carpalbonesCondyloid(ellipsoid) type Articular disc Distalend 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 Mostadduction @ wristjoint Abduction from the neutral position occurs @ midcarpaljoint. Flexion of thehand> Extension of thehand Adduction of thehand > Abduction of thehand
INTERCARPAL JOINTS Planetype • Joints between carpal bones of the proximal row • Joints between carpal bones of the distal row • Midcarpal jointbetween proximal &distal rows of carpal bones • Pisotriquetral jointpisiform with palmar surface of triquetrum Anterior, posterior, and interosseous ligaments
CARPOMETACARPAL & INTERMETACARPAL JOINTS carpometacarpal joint of the thumb between trapezium & base of 1st metacarpal
CARPOMETACARPAL & INTERMETACARPAL JOINTS Palmar and dorsal carpometacarpal ligaments Palmarand dorsal intermetacarpal ligaments Interosseus metacarpal ligaments Superficial and deep transverse metacarpal ligaments
METACARPOPHALANGEAL & INTERPHALANGEAL JOINTS • MORE IMAGES • 135-138 Metacarpophalangealjoints condyloidtype biaxialplane: flexion-extension and adduction-abduction Interphalangealjoints hinge type uniaxialflexion-extension only
