1

Spear Tackler's spine results in:

1) Loss of physiologic cervical lordosis
2) Cervical stenosis
3) Arthritic Changes

2

What is a stinger?

Symptoms are burning or skocking pain down the arm.
Cause: Brachial Plexus stretch
May get arm numbness or weakness
* C-5 is most common: Biceps, Deltoid, supraspinatus, infraspinatus

3

Most common level of cervical spine fracture

C5-6 (C4-5 and C6-7) next most common

4

Most common cause of cervical spine fracture

Leading with the head ( called Axial load(

5

Most common cause of lower thoracic spine fracture

Fall, axial load increase

6

Lumbar spine fracture location?

PARS (between the superior and inferior facets)

7

What muscles make up the rotator cuff

SITS

8

Weak empty can test?

Supraspinatus injury

9

Are most shoulder dislocations anterior or posterior?

Anterior- 90%

10

What is a sublexation?

Partial dislocation where humerus was just barely out of the glenoid fossa

11

What is a SLAP tear?

Labral tear

12

Acromiclavicular joint separation cause

Usually a fall on the tip of the shoulder

13

How many grades of AC joint separation are there?

Grade 1- ligaments are just stretched, tender on AC joint b/c of partial tear to AC ligament
Grade 2- tearing of Acromioclavicular ligament, but coracoclavicular still in tact. Clavicle will rise
Grade 3- all ligaments torn
Clavicle will rise all the way up

14

Most frequently fractured bone in the body is

clavicle

15

Criteria for surgery of clavicle fracture?

Must be skeletally mature
Fragmentation of the fracture site is a bad thing
More than 100% displacement
More than 2cm of bone overlap

16

Osteochonditis descicans

Little leaguers elbow. Lateral part of elbow

17

Symptoms of OCD

poorly localized elbow pain, aggravated with use, loose body-catching of elbow

18

Cause of OCD?

articular forces during throwing, compressive loads

19

How much flexion strength do you lose with a proximal biceps rupture>

about 10%

20

What about a distal biceps rupture?

about 15% but you lose 50% of supination strength

21

Pain over the medial side of the elbow?

Ulnar collateral Ligament injury
- pain is intensified with throwing maneeuver
-swelling and bruising occur
- numbness and tingling of ring and little finger
-weakened grip

22

UCL repair?

Tommy John Surgery

23

Scaphoid fracture

Tenderness in the snuff box, often hard to see on x-ray

24

Scaphoid bone is difficult to heal because it is mostly cortical bone, not much marrow capacity

true.

25

Jersey finger symptoms

cant flex the DIP. Usually a tear at the flexor digitorum profundus insertion

26

Mallet finger

Extensor tendon injury . Cant extend the DIP

27

Most common cause of Lumbar spine stress fracture of the PARS

Inappropriate weight lifting in young adolescent males

28

Most common sites of Lumbar disk herniation

L4/L5 and L5/S1

29

Which direction of shoulder dislocation is more common, anterior or posterior?

Anterior>>>>>>>>Posterior

30

What stabilizes the humerus from dislocation?

Anterior Inferior Glenohumeral LIgament
