1

Elbow instability subluxation & dislocation presents with?

FOOSH
may have: deformity, neural involvement, vascular involvement

2

Elbow instability fractures present with?

fat pad/effusion
inability to fully extend elbow
history of trauma

3

Common fracture of the elbow?

medial/lateral epicondyle
olecranon
radial head
coronoid process

4

Complications from fractures?

loss of extension
mild to moderate pain
popping/locking suggest loose body
ulnar neuritis
Heterotrophic ossificans
Complex regional pain syndrome

5

Heterotrophic ossificans present with?

pain with progressing loss of ROM

hyperemia, swelling, need for DD of septic arthritis, thrombophlebitis

may show increase serum alkaline phosphatase sedimentation rate and white blood count

xray may not show HO until 5th wk

6

Posterolateral rotatory instability presents with?

vague elbow pain
lateral elbow pain
clicking, clunking, with supination
pt. reports of something wrong with extention/supination, elbow giving out with loading flexed elbow into supination

7

Posterolateral rotatory instability MOI?

axial compression
valgus stress
supination, rotation at humeroulnar joint

8

Valgus instability presents with?

medial elbow pain
pop felt at time of injury
tender UCL

9

Valgus instability MOI

acute FOOSH or insidious overuse excessive valgus

10

Lateral tendinitis/osis presents with

point tenderness distal to humerus
difficulty gripping
pain with wrist flexion & active wrist extension
more common in: 30-50 yo, women>men increase level of work

11

Medial tendinitis/osis presents with

primary: prontator teres, FCR, palmaris longus
secondary: FCU, Flexor sublimis
male=female, 75 % dominant arm

12

Biceps tendon rupture presents with

pop at injury
acute weakness
deformity present

13

Bicepts tendon rupture MOI

rapid eccentric load with elbow supinated

14

Ulnar nerve- cubital tunnel syndrome

2nd most common nerve entrapment in UE
parasthesia along ulnar distribution
clumsiness/loss of coordination of hand
popping/snapping during active flexion/extension

15

Median nerve- pronator syndrome

anterior elbow pain
pain volar proximal forearm
sensing loss @ palmar surface of 2,3, quarter of 4
positive compression @ pronator border

16

Median nerve- anterior interosseous syndrome

pain volar proximal forearm
no sensory loss @ fingers, motor weakness: FPL, FDP, thenar sparing
negative compression @ pronator border
inability to make ok sign

17

Radial nerve- radial tunnel syndrome

deep ache distal to lateral epicondyle
pain at belly of brachioradialis
pain with resisted supination, repetitive wrist flexion/pronation
no motor/sensory loss

18

RAdial nerve-posterior interosseous syndrome

lateral forearm/elbow pain
weak wrist extension & radial deviation (loss of ECU)
loss of ED, EDM, weak extensors of finger
motor loss only, thumb extension produces pain @ lateral epicondyle

19

Osteoarthritis

males>female, 40-60yo
hx of repetitive use of UE in weight bearing occupation
loss of terminal extension, painful locking, pain @ end of flexion/extension
ulnawr neuropathy in 26-55% of pt. who go into surgery

20

Forearm compartment syndrome

increase forearm pressure due to exertional activity
chronic, gradual onset
weakness, numbness, pain that doesn't subside

21

Olecranon bursitis

acute onset, unexplained swelling
septic, slightly more in males
hx of recent abrasion, repetitive trauma, hx of diabetes
