Flashcards in Elbow Deck (16):
1

- most common overuse injury of elbow
- usually chronic and degenerative - repeated microtrauma leads to disruption of the tendon's internal structure
- angiofibroblastic hyperplasia
- involves ECRB, ECRL, ECU, EDM

lateral epicondylitis/osis
tennis elbow

2

- age 30-60
- oft associated with repetitive work, such as typing

lateral epicondylitis/osis
tennis elbow

3

- ℅ activity-induced dull, aching, lateral pain
- pain with resisted wrist extension and/or activities that involve extension with pronated forearm
- grip weakness
- ttp .5-1 inch distal to lateral epicondyle

lateral epicondylitis/osis
tennis elbow

4

- pain during active wrist extension
- pain with stretch of extensor muscles
- pain with passive elbow extension in more involved cases
- ttp over ECRB

lateral epicondylitis/osis
tennis elbow

5

differential dx
- referred pain from C nerve roots
- chronic irritation of radiohumeral joint
- bursitis at conjoined tendon
- radial neck fx
- little league elbow
- OCD of the elbow

lateral epicondylitis/osis
tennis elbow

6

- repetitive stress causes microtears to flexor tendons
- chronic inflammation
- involves pronator teres and FCR origins at medial epicondyle
- abn FCU and palmaris longus may also be present

medial epicondylitis/osis

7

- athletes: tennis, throwing, golf, etc
- degenerative: tendon fails to heal properly after repetitive microtrauma
- UCL doesn't stabilize valgus force properly - strains tendon

medial epicondylitis/osis

8

- decreased grip strength
- possible ulnar neuropathy
- localized tenderneds to medial epicondyle and muscle masses

medial epicondylitis/osis

9

- gradual onset medial epicondyle pain
- agg: serve and forearm strokes in sports, resisted/active wrist flexion and pronation

medial epicondylitis/osis

10

- inflammation of subcutaneous bursa overlying olecranon process

olecranon bursitis (student's elbow)

11

- can be caused by acute injury with direct blow
- can be chronic irritation with gradual fluid accumulation
- greater risk with repetitive movement or computer work involving leaning on elbow

olecranon bursitis (student's elbow)

12

- pain
- limited ROM at elbow, esp with flexion
- swollen posterior elbow
- if caused by infection, may be warm and red
- can appear spontaneously
- elbow at 70˚ flexion at rest

olecranon bursitis (student's elbow)

13

- UCL valgus overload (aka VEOS)
- chronic UCL insufficiency - microscopic tears to ligament
- acute rupture - most commonly to anterior oblique band

UCL injuries

14

- common in OH throwing athletes
- progressive discomfort after throwing
- significantly decreased speed
- sudden onset of pain or elbow giving way during throwing
- acute pop may be heard

UCL injuries

15

- pain and soreness over medial epicondyle, especially in late cocking to early acceleration phase
- ℅ instability

UCL injuries

16

- limited ROM
- may have painful arc
- decreased strength of flexion
- ulnar nerve signs may be present
- ttp at sublime tubercle
