2. WRIST & HAND ANATOMY Fingers named by #1-5 starting at the thumb
Joints named after the bones that come together
Muscles:
Wrist extensors are posterior on the forearm
Wrist flexors are anterior on the forearm

3. WRIST & HAND ANATOMY Ligaments: Triangular fibrocartilage complex
Every finger has 2 collateral ligaments
Radial/lateral collateral ligament
Ulnar/Medial collateral ligament
Triangular fibrocartilage complex

4. Anatomical Snuff Box The boundaries
The posterior border of the snuffbox is the tendon of the extensor pollicis longus.
The anterior border are the extensor pollicis brevis and the abductor pollicis longus.[1]
The proximal border is formed by the styloid process of the radius
The floor of the snuffbox varies depending on the position of the wrist, but both the trapezium and primarily the scaphoid can be palpated.

5. TFCC The Triangular fibrocartilage complex (TFCC) is formed by:
Triangular fibrocartilage discus (TFC)
Radioulnar ligaments (RUL’s)
Ulnocarpal ligaments (UCL’s).

6. DeQuervain’s Tendonitis
Tendonitis of the abductor pollicus longus and extensor pollicus brevis (muscles that move that thumb)
AKA as “Trigger Finger”
MOI: Repetitive motion (radial deviation) of the wrist
Signs/Symptoms:
Pn with abduction
Swelling
Crepitus
Treatment:
RICE
NSAIDS
Strengthening of hand muscles

7. Mallet Finger MOI: Hit at the tip of the finger
Extensor tendon tears from bone
Signs/Symptoms:
Finger is in flexion
Cannot straighten finger because tendon is unattached
Management:
Pain
Swelling
Splint in extension
Surgery to reattach

8. Jersey Finger Flexor tendon tears away from fingertip
MOI: DIP jt is in flexion and is suddenly forced to extend (i.e. grabbing a jersey)
Signs/Symptoms:
Pain
Swelling
DIP jt is unable to flex
Management:
Splint
Ice
Surgery

9. Wrist Sprain Management: MOI: FOOSH Excessive radial/ulnar deviation
Signs/Symptoms
Pain
Decreased ROM
Decreased grip strength
Swelling
Laxity
Management:
RICE
Splint
Rehab to strengthen hand muscles

10. Ganglion Cyst
Occurs when the sheath covering the muscles becomes filled with fluid
A.K.A. “Bible’s cyst”
Signs/Symptoms:
Bubble develops on wrist
Painful at times
Management:
Ice with compression
If persistent, needs to be drained by physician

11. Gamekeeper’s Thumb
MOI: Injury to medial collateral ligament of thumb due to forced abduction
(i.e. catching a basketball)
Signs/Symptoms:
Pain
Swelling
Loss of ROM
Management:
Ice
Splint
Xray to r/o fx

12. Interphalangeal Collateral Ligament Sprain
MOI: Joint is stressed beyond normal limits
I.e. finger hits a ball, land with fingers extended or curled
Signs/Symptoms:
Pain
Swollen
Ecchymosis
Loss of ROM
Management:
XRAY to r/o fx
Ice in ice cup
Splint

13. Dislocation of Interphalangeal or Metacarpophalangeal Joints
MOI: Bones of joint are forced in opposite directions
Signs/Symptoms:
Obvious deformity
Pain, Swelling
Ecchymosis
Loss of ROM
Management:
Refer to physician for reduction
