Elbow Joint 1 Flashcards
Joints of the Elbow (3)
- Humeroradial
- Humeroulnar
- Radioulnar
Main ligaments of the Elbow (3)
- Annular ligament
- Ulnar collateral
- Radial collateral
Carrying angle in Men and Women
Men: 11-14 degrees
Women: 13-16 degrees
What is the disorder of an increased cubital angle?
Ulnar palsy
Humeroradial: Close-packed position
Elbow flexed to 90, forearm supinated to 5
Humeroradial: Capsular patterns
Flexion, Extension, Supination, Pronation
Humeroulnar: Close-packed position
Extension with supination
Humeroulnar: Capsular patterns
Flexion, extension
Radioulnar: Closed-packed position
5 degrees supination
Radioulnar: Capsular patterns
Equal limitation of supination and pronation

Syndromes: Anterior (4)
- Ant. Capsular strain
- Biceps rupture

Syndromes: Medial (4)
- Med. Epicondylitis
- MCL injury
- Ulnar neuritis
- Fracture
Syndromes: Posterior (3)
- Olecranon bursitis
- Olecranon process stress fracture
- Triceps tendinitis
Syndromes: Lateral (6)
- Lat. Epicondylitis
- LCL injury
- Capitulum fracture
- Osteochondral degenerative -Osteochondritis dissecans
- Radial head fracture
Trauma vs. Overuse injuries
- Trauma: FOOSH, Fall on the tip of elbow, Ligament injury
- Overuse: Epicondylitis, Little Leaguer’s elbow
Epicondylitis
Inflammation of one of the epicondyles, which includes both the periosteum and the tendons
Lateral epicondylitis is more common than medial epicondylitis
Lateral epicondylitis is known as:
Tennis elbow
Medial epicondylitis is known as:
Golfer’s or Thrower’s elbow
Lateral epicondylitis
-Inflammation of the insertion of the extensor carpi radialis brevis (ECRB) and extensor carpi radialis longus (ECRL)
Symptoms of L. epicondylitis
Lateral elbow pain with insidious onset, pain with wrist extension, weakened grip strength
Stage 1 - L. Epicondylitis
Inflammation w/o alteration in the tendons
Stage 2
Associated with pathological changes in the tendon or angiofibroblastic degeneration
Stage 3
Pathological changes in the tendon and partial rupture
Stage 4
Characteristics of the stage 2 and 3 plus fibrosis, soft matrix calcifications, and faint calcifications along the epicondylar margins
Chair test is used for:
L. epicondylitis
Lift chair with pronated hand
Special tests for L. Epicondylitis
- Finger extension
- Mill’s test (more like a stretch)
- Cozen’s test (more like strength test)
Ther Ex for L. Epicondylitis
- Extensor eccentric exercises (with bendy stick)
- Towel wrings
Medial Epicondylitis
Inflammation of the insertion of the Flexor carpi radialis (FCR) and Pronator teres
M. Epicondylitis - Symptoms
- Medial elbow pain
- Pain with wrist flexion and pronation
M. Epicondylitis - Special tests
- Resisted wrist flexion
- Passive stretch (elbow and wrist extension)
Little Leaguer’s elbow (6)
- Osteochondritis dissecans of the radial head
- Growth plate fractures
- Apophysitis or fracture of the medial epicondyle
- Ulnar CL tear
- Anterior capsular injury
- Olecranon trauma
MOI: Little Leaguer’s
- Excessive valgus stress and hyperextension and overuse
- High pitch volume
- Early use of the curve and slider
- Inadequate biomechanics
