3 joints of elbow |
Humeroulnar Humeroradial Proximal Radioulnarra |
|
Radioulnar joint |
Pivot joint, radius articulates with head of ulna. Pronation and supination |
|
Muscles of elbow and radioulnar joints |
Anterior (elbow): biceps brachii brachialis, brachioradialis, pronator teres Anterior (wrist): pronator quadratis Posterior; triceps brachii, aroneus, supinator |
|
Biceps brachii |
Flexes and supinates the forearm |
|
Brachialis |
Flexion at elbow |
|
Brachioradialis |
Contributes to elbow flexion |
|
Pronator teres |
Primates the forearm, assists in elbow flexion |
|
Pronator quadratus |
Pronation of forearm |
|
Triceps brachii |
Powerful elbow extension |
|
Supinator |
Supinator of forearm |
|
Aconeus |
Works with triceps to extend forearm |
|
Flexion of elbow |
Brachialis involved in all movements. Biceps brachii most active in supination, least with pronation |
|
Radiocarpal joint |
Condyloid joint 4 ligaments: Volare radiocarpal, dorsal radiocarpal, ulnar collateral, radial collateral Flexion, extension, radial and ulnar deviation |
|
Midcarpal and intercarpal joints |
Proximal row of 4 carpal bones articulate with 4 carpal bones of distal row. Permits only slight gliding. |
|
Carpometacarpal and internet carpal joints |
Thumb is prime example of a saddle joint. Joints between the bones are irregular |
|
Movements of thumb |
Back (Definition) |
|
Movements of carpometacarpal and intermetacarpal joints |
Because of short ligaments, motion is almost non existent. Limited to slight gliding. 5th carpometacarpal joint is slightly more mobile |
|
Metacarpophalangeal joints |
Joints at bases of four fingers. Condyloid joint. Protected by collateral ligaments. Also a dorsal ligament. Movements: adduction/Abduction, flexion/extension |
|
Metacarpophalangeal joints |
Joints at bases of four fingers. Condyloid joint. Protected by collateral ligaments. Also a dorsal ligament. Movements: adduction/Abduction, flexion/extension |
|
Movements of metacarpophalangeal joints of thumb |
Flexion: volar surface of thumb approaches base of thumb Extension: return movement |
|
Interphalangeal joints |
Joints between adjacent phalange of any of the five digits. All are hinge joints, flexion and extension Strengthen by collateral ligaments and in front by volar ligament |
|
Flexor carpi radialis |
Flexes wrist Radial deviation |
|
Flexor carpi ulnaris |
Flexes wrist Ulnar deviation |
|
Palmaris longus |
Weakly flexes wrist |
|
Extensor carpi radialis |

Result of direct blow or falling on outstretched hand. Usually both ulna and radius fracture |
|
Fractures |
Result of direct blow or falling on outstretched hand. Usually both ulna and radius fracture |
|
Elbow dislocation and fracture |

|
Elbow dislocation and fracture |
Falling on outstretched hand. Most common is backward displacement of ulna and radius in relation to humerus |
