What Causes...

 

1. Medial elbow pain 

2. Lateral Elbow Pain 

3. Tennis & golfer's elbow

1. UCL (Tommy-John Ligament)

2. RCL or annual lig abt radial head

3. Lateral(tennis) & medial epicondylitis (golf)

 

 

3

1. What forms carrying angle? 

 

2. What does increasing it cause...

Decreasing it....

1. Angle formed at the elbow b/w2 lines ...

1st along long axis of humerus 

2nd median aspect of forearm  in valgus position 

 

2. Inc= wrist aDduction

Dec= wrist ABduction 

(i like to remember this as Decrease already has a D in it so it adds a B)

4

1. normal degrees for men & women 

 

2. Greater than

 less than normal

1. women 10-15 °   

men 5°

 

2. Cubitus Valus ... If >

Cubitus varus -aka- Gun Shot..If <  

 

5

Parallelogram of Forearm 

As Olecranon of the ulna

1. aBducts ...the wrist--> 

2. aDucts ....the wrist-->

 

Oppostite...

The wrist

1. aDducts (movement of wrist toward pinkie)

 

2. aBducts (mvmt of the wrist toward thumb)

as the olecranon....

6

Somatic Dysfunction of Elbow

-aka-

 Olecranon (ulnohumeral) Dysfunction

1. Clincial

2. Primary & Secondary cause

1. Cause- Subtle Add or Abd elbow

 

2. Primary- Olecranon (ulnohumeral) joint SD

Secondary- radiohumeral joit 

 

7

Olecranon  (ulnohumeral) SD

aBduction 

 

1. Type of Glide

2. Carrying angle

3. Distal forearm prefers (Da same)

4. Radial head is..

5. Hand (wrist) may prefer... (Hoppostie)

1. Medial Glide

 

2. Increased Carrying angle 

 

3. Distal Forearm Prefers -aBduction

 

4. Radial Head- compressed on the capitulum of humerus

 

5. Hand (wrist) aDduction at radiocarpal joing

8

Olecranon  (ulnohumeral) SD

aDduction 

 

1. Type of Glide

2. Carrying angle

3. Distal forearm prefers (Da same)

4. Radial head is..

5. Hand (wrist) may prefer... (Hopposite)

1. Lateral Glide

 

2. Gunshot -aka- Decreased carrying angle 

 

3. Distal Forearm- aDduction 

 

4. Radial Head gapped at capitulum & drawn into annular lig

 

5. Hand (wrist)- aBduction at radiocarpal joint

9

Muslces of Supination and Pronation

Supinate- Supinator

 

Pronate- Pronator teres & pronator quadratus 

10

Radial Head Dysfunction

  • Radius has Reciprical motion 

 

  • Pronate hand= Posterior glide of Radial head

 

  • Supinate hand= Anterior glide of Radial head 

11

Pronation 

 

1. Radius crosses....

2. Creates...

3. Distal Radius moves___ causes Radial Head to  move__

1. Radius crosses - Ulna

2. Creates Fulcrum

3. Distal radius moves anteriorly ... causes radial head to move 

Posteriorly 

 

12

SUPINATION 

 

At endpoint distal radius moves _______

 

______causes raidal head to glide _____

 

At endpoint distal radius moves _______ (posteriorly)

 

______(interosseous lig) causes raidal head to glide _____ (anteriorly)

13

Cause of SD

Hand is in..

1.  Pronation

2. Supination

 

 

1. Pronation- Fall forward & bracing with hands

Result: Posterior radial head

 

2. Supination- Backward fall & Bracing with hands

Result: anterior radial head

 

14

 

RAIDAL HEAD MNEMONIC 

 

SAPP 

Supination of Forearm= Anterior radial head

 

Pronation of forearm= Posterior radial head 

15

16

Falling Forward onto palm

with out stretched palm causes...


1. The hand is in a pronated position

2.  forward force vector pushes the distal radius into greater anterior rotation

3. causing the radial head to move posteriorly
 

17

FALLING BACKWARD ONTO PALM 

w/ Extended Arm

 

  1. ¨The hand is in a supinated position

 

2. impacting force vector pushes the distal radius into greater posterior rotation

 

     3. causing the radial head to move anteriorly.
 

18

When evaluating Joints look for SD always look in....

 

 

1 joint up and 1 joint down

19

SD WRIST 

  • Pain in wrist -- small gliding motion

 

  • look at elbow- might have large motion loss in flex & ext

 

  •  Compression compenent - if cause by fall

20

SD CMC (Carpometacarpal) Joint

 

Almost always have a _______component

especially if  motion is restricted in _____and/or ______

Almost always have a _______( compression) component

especially if  motion is restricted in _____(dorsal) and/or ______(ventral) GLIDE 

21

1st CMC (thumb) most like to have.......

  • compression strain or true sprain (NOT SD)

 

  • Due to freedom of motion 

22

MCPs or IPs SD in  (3 things)

accompanied by______

 

  1.  AP glide
  2. Mediolateral glide
  3. Rotational Glide (internal/external)

 

Accompanied by___________(compression)
