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
WRIST & HAND ANATOMY Ligaments:
Every finger has 2 collateral ligaments
Radial/lateral collateral ligament
Ulnar/Medial collateral ligament
Triangular fibrocartilage complex
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.
TFCC
The Triangular fibrocartilage complex (TFCC) is formed by: Triangular
fibrocartilage discus (TFC)
Radioulnar ligaments (RUL’s)
Ulnocarpal ligaments (UCL’s).
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
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
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
Wrist Sprain MOI:
FOOSH Excessive radial/ulnar
deviation Signs/Symptoms
Pain Decreased ROM Decreased grip strength Swelling Laxity
Management: RICE Splint Rehab to strengthen
hand muscles
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
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
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
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
