2 The joints of the bones of limbs SHANDONG UNIVERSITY Liu Zhiyu

3 一、 The joint of upper limb

4 (一) The joints of shoulder girdle 1 、 Sternoclavicular Joint : Characteristic : , articular disc Articular disc Composition: Sternal end of clavicle Clavicular notch of sternum

5 (一) The joints of shoulder girdle Movements: forwards and backwards (20-30 ° ) elevation and depression (60 ° ) circumduction

6 Composition : 3 、 Coracoacromial Ligament Coracoacromial arch : Coracoacromial Ligament 2 、 Acromioclavicular Joint acromion coracoacromial lig. coracoid process Acromion coracoid process

7 (二) The joints of free upper limb 1 、 Shoulder Joint Glenoid cavity Head of humorus 肱骨头 Characteristic : head of humerus glenoid cavity of scapula Composition :

8 Accessory structures 1)Glenoid labrum : 2)Coracohumeral ligament

9 Movements: flexion and extention, adduction, abduction, medial and lateral rotation, circumduction

10 2 、 Elbow Joint ① Humeroulnar joint : formed by trochlear of humerus and troclear noch ② Humeroradial joint : formed by capitulum of humerus and head of radius ③ Proximal radioulnar joint : formed by articular circumference of radius and radial notch of ulna Composition:

11 Character : ① capsule: ② l igament : Radial collacteral ligament 、 Ulnar collacteral ligament 、 Annular ligament of radius Annular ligament of radius Radial collacteral ligament Ulnar collacteral ligament

12 Movements: flexion and extension, pronation supination

13 3 、 Joints between radius and ulna ( 1 ) Interosseous membrane of forearm ( 2 ) Proximal radioulnar joint ( 3 ) Distal radioulnar joint movement Pronation supination

14 4 、 Joints of Hand ( 1 ) Radiocarpal Joint Composion Articular fossa —— Carpal articular surface of radius and articular disc below the ulna Articular head —— Proximal row of carpal: scaphoid, lunate, and triquetral bones, but not pisiform Characteristic : Capsule is lax and strengthened by surrounding ligament Movements : flexion , extension , adduction , abduction circumduction

15 4 、 Joints of Hand ( 2 ) Intercarpal joints ( 3 ) Carpometacarpal joints : Carpometacarpal joint of thum Carpometacarpal joint of thumb Composition: trapezium and base of first metacarpal Movement: flexion, extension, adduction, abduction, and opposition

16 ( 4 ) Metacarpophalangeal joints ( 5 ) Interphalangeal joints
