| Question | Answer |
| How many degrees of freedom does the glenohumeral joint have ? | 3 |
| What are all the possible osetokinematic motions for the gelnohumeral joint? | Flexion Extension ABD ADD Medial rotation External rotation Horizontal ABD/ADD |
| What is the close pact position for the gelnohumral joint? | ABD Lateral rotation |
| What is the open pact position for the gelnohumeral joint? | 55 degrees ABD 30 degrees horizontal ADD |
| What is a capsular pattern? | Refers to the limitation of a joint due to inflammation, OA, etc. Every joint has predictive limitations. |
| What is the capsular pattern of the gelnohumeral joint? | Lateral rotation ABD Medial rotation |
| How many degrees of freedon does the sternocalvicular joint have? | 3 |
| What are all the possible osetokinematic motions for the sternocalvicular joint? | Elevation Depression Upwards rotation Downwards rotation Protraction Retraction |
| What is the loose pack position for the sternocalvicular joint? | Arm resting by side |
| what is the close pack position for the sternocalvicular joint? | Maximum shoulder elevation |
| How many degrees of freedom does the acromiocalvicular have? | 3 |
| What are all the possible osetokinematic motions for the amcromiocalvicular joint? | Anterior tilt Posterior tilt Upward rotation Downward rotation Protraction Retraction |
| What is the loose pack position for the acromiocalvicular joint? | Arm resting by side |
| What is the close pack position for the acromiocalvicular joint? | Arm ABD at 90 degrees |
| What are all the possible osetokinematic motions for the radiohumeral joint? | Flexion Extension Pronation Supination |
| What is the loose pack position for the radiohumeral joint? | Full extension and supination |
| What is the close pack position for the radiohumeral jonit? | 90 degrees of flexion 5 degrees of supination |
| What is the capsular pattern for the radiohumeral joint? | Supinaion Pronation extension Flexion |
| What are all the possible osetokinematic motions for the ulnohumeral joint? | Flexion Extension |
| What is the loose pack position for the ulnohumeral joint? | 70 degrees elbow flexion 10 degrees of supination |
| What is the close pack position for the ulnohumeral joint? | extension |
| What is the capsular pattern for the ulnohumeral joint? | flexion extension |
| What are all the possible osetokinematic motions for the radioulnar joint? | Pronation Supination |
| What is the loose pack position for the radioulnar joint? | 70 degrees of elbow flexion 35 degrees of supination |
| What is the close pack position for the radioulnar joint? | 5 degrees of supination |
| What are the capsular pattern for the radioulnar joint? | supination Pronation |
| Where is the lateral collateral ligament of the eblow? and the other term for it? | Radial collateral ligament Lateral epicondyle of the humerus to the olecranon process. |
| What is the medial collateral ligament of the elbow? and the other term for it? | Ulna collateral ligament Medial epicondyle of the humerus to the proximal portion of the ulna |
| What is the function of the lateral collateral ligament of the elbow? | Prevents ADD of the elbow |
| What is the function of the medial collateral ligament of the elbow? | Prevent ABD of the elbow |
| What is most common mechanism of elbow injury? | Over stretch of ligaments in the elbow due to overuse. This is common in athletes. Over time small tears occur in the ligament till it finally ruptures. |
| Where is the annular ligament and it's purpose? | It covers the radial head and it allows the radial to rotate while keeping in contact with the ulnar notch. |
| What are all the possible osetokinematic motions for the radiocarpal joint? | flexion extension radial deviation unlar deviation |
| What is the loose pack position of the radiocarpal joint? | neuteral with slight unlar deviation |
| What is the close pack position for the radiocarpal joint? | extension with redial deviation |
| What is the capsular pattern for the radiocarpal joint? | flexion extension |
| What is the purpose of the dorsal radiocarpal ligament? | Prevents excessive wrist flexion |
| What is the purpose of the palmar radiocarpal ligament? | Prevent hyperextension of the wrist |
| What is the purpose of the radial collateral ligament of the wrist? | Prevents excessive ulnar deviation |
| Where is the interosseous membrane and it's purpose? | Between the shaft of the radius and ulnar which stabilizes against forces to the wrist. |
