HAND INJURIES
FINGER AND THUMB ABNORMALITIES
FRACTURED PHALANGE
ANATOMY OF THE PHALANX
• DIP versus PIP
MALLET FINGER
• Distal Phalanx is
forcefully flexed
and tears the
extensor tendon at
the DIP joint
MALLET FINGER
TREATMENT FOR MALLET FINGER
• Splint is slight
hyperflexion for 6-8
weeks
• DO NOT REMOVE
RUPTURE OF EXTENSOR TENDON PIP
JOINT
BOUTONNIERE FINGER
• MOI: forceful blow
to bent finger
• Laceration that cuts
extensor tendon
• Arthritis – 1/3 of
patients
• TX – splint – 6wks or
surgery to repair
tendon.
SWAN NECK DEFORMITY
SWAN NECK DEFORMITY
SWAN NECK DEFORMITY
• MOI – arthritis /
imbalance of
muscle forces on
the PIP joint
• Treatment –
splinting and PT to
align the two joints
SWAN NECK AND BOUTONIERRE
GAME KEEPERS THUMB
• Tear of the ulnar
collateral ligament
of the MP joint of
the thumb
• MOI – abduction
and hyperextension
• Skiing
TX: SPLINT OR POSSIBLE SURGERY
METACARPAL FRACTURES
• MOI – direct blow
• S&S-ecchymosis in
palm
• TX – x-ray - splint
ECCHYMOSIS OF PALM
WRIST SPRAIN
• MOI – FOTOSA with
hyperextension (
land on palm) or
hyperflexion (land
on back of hand –
wrist flexed)
WRIST SPRAIN
• S&S – loss of ROM
and strength
• TX- RICE, splint, tape
for activity
NAVICULAR/SCAPHOID FRACTURE
• S&S – point tender
in anatomical
snuffbox, pain with
compression of 1st
and 2nd
metacarpals
SCAPHOID/NAVICULAR FRACTURE
• MOI –
hyperextension of
wrist while falling
• Commonly missed –
mimics a sprain
SURGICAL SCREW – SCAPHOID
FRACTURE
COMPLICATIONS
• Non-displaced –
cast
• Non-union fracture
is common due to
disrupted poor
blood supply- bone
necrosis.
• Non-union usually
occurs when
unrecognized.
FINGER DISLOCATION
• MOI – high speed
force to distal
phalanx
• Most common – PIP
joint – proximal
interphalangeal joint.
• S&S – visual deformity,
immobility
• Complication –
fracture, Boutonneire
deformity
