Elbow |
Elbow aka: -humeroulnar joint -Also huneroradial joint -Superior radioulnar joint |
|
|
The elbow joint is... |
Synovial Compound joint -distal humerus -proximal radius -proximal ulna Single capsule Hinge joint for flexion and extension |
|
|
Proximal Radioulnar joint |
Part of elbow joint complex -not needed for flexion/extension Radial notch of ulna (+) radial head (+) annual ligament Allows pronation and supination |
|
|
Movement ROM's |
Flexion: 150 Extension: 0 or beyond Pronation: 0-90 Supination:0-90 |
|
|
Medial (ulnar) collateral ligament |
-provides protection against valgus stresses to the elbow |
|
|
Lateral (ulna) collateral ligament |
-provides protection against varus stresses to the elbow |
|
|
Annular ligament |
Holds radial head in place |
|
|
Biceps Beachii |
O: Long Head: Glenhoid and labrum. O: Short Head: Coracoid process I: Proximal Raidus A: Shoulder Flexion, Elbow Flexion, Wrist Supination |
|
|
Brachialis |
O:Humerus I:Ulna A:Elbow Flexion |
|
|
Brachioradialis |
O:Humerous I:distal Radius A: Elbow Flexion |
|
|
Tricep Brachii |
O: Long head: Glenoid O: Lateral Head: Upper part of posterior Humerous O: Medial Head: Middle part of posterior humerus I: Olecranon process of ulna A: Elbow extension |
|
|
Anconeus |
O:Lateral Humerous I: Olecranon and Ulna A: Elbow Extension |
|
|
Pronator Teres |
O: Medial Epicondyle of Humerous I: Middle Radius A:Wrist pronation, elbow flexion |
|
|
Supinator |
O: Lateral Epicondyle of humerous and lateral ulna I: Radius A:Supination |
|
|
Elbow Bursitis |
Bursa sac of fluid to protect the olecranon process -Allows skin to move freely -can get injured: Trauma Prolonged pressure Infection |
|
|
Humerus and Ulna become disarticulated |
Extreme trauma -fall at high speed -MVA |
|
|
Elbow Dislocation |
Can be open or closed. May sever artery or nerve. Reduction may be painful May or may not require surgery -may not regain full motion |
|
|
Elbow Arthrofibrosis |
-Unable to regain full ROM -Loss of Elbow extension -May be permanent |
|
|
Elbow fracture |
Due to trauma May or may not require surgery Depends on alignment |
|
|
UCL |
Stressed with valgus force at the elbow -Pitchers, Throwers -May rupture -May require surgery |
|
|
Distal Biceps tendon rupture |
-Sharp pain in arm -Black and blue -Popeye sign -Usually does not require surgery |
|
|
Elbow Arthritis |
Disruption of the articular cartilage of the humerus or ulna. - may or may not have pain |
|
|
Elbow Joint Replacement |
-End stage orientation -for pain relief -hard to regain full motion |
