2 Elbow Anatomy Elbow joint is made of 3 bones 2 joints One capsule Hinge jointFlexion(145) and extension
3 Elbow AnatomyElbow joint- where the radius and ulna articulate with the humerus.Flexion and extension-hinge joint
4 Elbow Anatomy Radialulnar joint- where the radius and ulna articulate. How many of this joint are there???
5 Elbow Anatomy Radioulnar joint is a pivot joint. It allows supination and pronation.
6 Elbow Anatomy The ulna does not move. The radius moves around the ulna.The ulna is locked in place by theproximal end at the olecranon process.
7 Elbow AnatomyInfraglenoid tubercle- inferior lip of the glenoid fossa, where the long head of triceps attaches.
8 Elbow AnatomySupraglenoid tubercle- superior portion of the glenoid fossa. Where the long head of biceps attaches.
9 Elbow AnatomyCapitulum- lateral side of joint, it articulates with the radius.
10 Elbow AnatomyMedial epicondyle- medial side of humerus at distal end just above trochlea. Pronator teres attachment.
11 Elbow AnatomyLateral epicondyle- located on lateral side of distal end above capitulum. Anconeus and supinator attach.
12 Elbow AnatomyOlecranon fossa- posterior surface of the humerus between the medial and lateral epicondyles.
13 Elbow AnatomyOlecranon process- proximal end of ulna, on posterior surface. The point of elbow where triceps attaches.
14 Elbow AnatomyTrochlea- located on the medial side of the distal end of the humerus. Articulates with ulna.
15 Elbow AnatomyCoronoid Process- just below the trochlear notch and next to the radial notch. Attachment for brachilis.
16 Elbow AnatomyStyloid Process- distal end of the lateral/medial surface at the ulna or radius.
17 Elbow AnatomyUlnar head- distal end on the lateral surface, radial head pronates around it.
18 Elbow AnatomyRadial head- proximal end, where it articulates with the capitulum.
19 Elbow AnatomyRadial tuberosity- attachment for the biceps muscle. On medial side of radius just distal to the radial head.
20 Elbow LigamentsMedial Collateral Ligament- runs from medial epicondyle of humerus to the medial side of coranoid process and olecranon process.
21 Elbow LigamentsLateral collateral ligament- attaches proximally to the lateral epicondyle and distally to the lateral ulna and annular ligament.
22 Elbow LigamentsAnnular Ligament- encompasses radial head at the radial notch and hold it against the ulna. (red)
23 ElbowInterosseous membrane- broad flat membrane is located between the radius and ulna for most of their length.
24 EpicondylitisOveruse of the tendon attached to the epicondyle of the humerus.Faulty technique/mechanics, weak muscles or improper equipment.Can be on lateral side- tennis or golfers elbowCan be on the medial side- pitcher’s elbow
25 Epicondylitis Signs and Sx Treatment Pain over epicondyle Increase pain with wrist flexion or extensionElbow contractureTreatmentProper techniqueProper equipmentGood warm up with slow increase in intensityStretchingRICE
26 Young Athlete’s Elbow Injury Little Leaguer’s elbow-repetitive action resulting in elbow pain in youngThe elbow area is the last epiphyseal center to close so injuries can occur.
27 Young Athlete’s Elbow Injury Little Leaguers elbow can result in in varies fractures or bone growths.
28 Dislocations Elbow is the second most commonly dislocated major joint. Most often the ulna/radius dislocate posterior to the humerus.MOI- fall of outstretched arm with elbow locked in extension.
29 Dislocations Signs and Sx Treatment Obvious deformity Check circulation and nerve functionTreatmentImmobilizationWrist strengthening and then progress to elbowRICE
30 Fractures to Elbow/Forarm Often occurs due to a direct blow or a fall on outstretched arm.Most common childhood injury, often involves the epiphysis.
31 Fractures to Elbow/Forarm Signs and SxPoint tendernessPossible deformitySwellingLimited ROMTreatmentImmobilizationRICEStrengthening of the joints surrounding and then whole arm when cast is removed.Splinting?
32 Elbow/Forearm Muscles Brachialis- attaches distal half of the humerus to the coronoid process and ulnar tuberosity of ulna.
33 Elbow/Forearm Muscles Biceps BrachiiLong head-supraglenoid tubercle, through bicipital groove, joins with theShort head- comes from the coracoid processBoth combine to inset onto the radial tuberosity.
