Forearm, Wrist and hand - Masterson Flashcards
What Causes…
- Medial elbow pain
- Lateral Elbow Pain
- Tennis & golfer’s elbow
- UCL (Tommy-John Ligament)
- RCL or annual lig abt radial head
- Lateral(tennis) & medial epicondylitis (golf)
- What forms carrying angle?
- What does increasing it cause…
Decreasing it….
- Angle formed at the elbow b/w2 lines …
1st along long axis of humerus
2nd median aspect of forearm in valgus position
- Inc= wrist aDduction
Dec= wrist ABduction
(i like to remember this as Decrease already has a D in it so it adds a B)
- normal degrees for men & women
- Greater than
less than normal
- women 10-15 °
men 5°
- Cubitus Valus … If >
Cubitus varus -aka- Gun Shot..If <
Parallelogram of Forearm
As Olecranon of the ulna
- aBducts …the wrist–>
- aDucts ….the wrist–>
Oppostite…
The wrist
- aDducts (movement of wrist toward pinkie)
- aBducts (mvmt of the wrist toward thumb)
as the olecranon….
Somatic Dysfunction of Elbow
-aka-
Olecranon (ulnohumeral) Dysfunction
- Clincial
- Primary & Secondary cause
- Cause- Subtle Add or Abd elbow
- Primary- Olecranon (ulnohumeral) joint SD
Secondary- radiohumeral joit
Olecranon (ulnohumeral) SD
_aBduction _
- Type of Glide
- Carrying angle
- Distal forearm prefers (Da same)
- Radial head is..
- Hand (wrist) may prefer… (Hoppostie)
- Medial Glide
- Increased Carrying angle
- Distal Forearm Prefers -aBduction
- Radial Head- compressed on the capitulum of humerus
- Hand (wrist) aDduction at radiocarpal joing
Olecranon (ulnohumeral) SD
aDduction
- Type of Glide
- Carrying angle
- Distal forearm prefers (Da same)
- Radial head is..
- Hand (wrist) may prefer… (Hopposite)
- Lateral Glide
- Gunshot -aka- Decreased carrying angle
- Distal Forearm- aDduction
- Radial Head gapped at capitulum & drawn into annular lig
- Hand (wrist)- aBduction at radiocarpal joint
Muslces of Supination and Pronation
Supinate- Supinator
Pronate- Pronator teres & pronator quadratus
Radial Head Dysfunction
- Radius has Reciprical motion
- Pronate hand= Posterior glide of Radial head
- Supinate hand= Anterior glide of Radial head
Pronation
- Radius crosses….
- Creates…
- Distal Radius moves___ causes Radial Head to move__
- Radius crosses - Ulna
- Creates Fulcrum
- Distal radius moves anteriorly … causes radial head to move
_Posteriorly _
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)
Cause of SD
Hand is in..
- Pronation
- Supination
- Pronation- Fall forward & bracing with hands
Result: Posterior radial head
- Supination- Backward fall & Bracing with hands
Result: anterior radial head
RAIDAL HEAD MNEMONIC
**SAPP **
Supination of Forearm= Anterior radial head
Pronation of forearm= Posterior radial head
Falling Forward onto palm
with out stretched palm causes…
- The hand is in a pronated position
- forward force vector pushes the distal radius into greater anterior rotation
- causing the radial head to move posteriorly
FALLING BACKWARD ONTO PALM
w/ Extended Arm
- ¨The hand is in a supinated position
- impacting force vector pushes the distal radius into greater posterior rotation
- causing the radial head to move anteriorly.
When evaluating Joints look for SD always look in….
1 joint up and 1 joint down
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
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 _
1st CMC (thumb) most like to have…….
- compression strain or true sprain (NOT SD)
- Due to freedom of motion
MCPs or IPs SD in (3 things)
accompanied by______
- AP glide
- Mediolateral glide
- Rotational Glide (internal/external)
Accompanied by___________(compression)
