2. WHAT IS CLAW HAND ?
Claw Hand is a condition in which your fingers are noticeably curved or
bent. This condition can affect one or more of your fingers, on one or both
hands.
The condition gets its name from the curvature of fingers, which makes the
hand resemble a bear’s claw.

present at birth) or it may be due to certain disorders
or injuries.

previous slide indicates

NERVE
INJURY/DAMAGE.

6. TYPES OF CLAW HAND
Partial or Ulnar Claw Hand Complete Claw Hand

7. PARTIAL OR ULNAR CLAW HAND
A hand in ulnar claw hand position will have the 4th and 5th fingers hyperextended at
the metacarpophalangeal (MCP) joints and flexed at the interphalangeal (PIP) joints.
How to check for ulnar claw hand ?
Patient will able to make full fist but when they extend their finger they won’t be able
to do it.

10. REASONS FOR ULNAR NERVE INJURY ARE:
•Entrapment of ulnar nerve
•Bone fracture or dislocation
•Swelling of soft tissue
•Wrist Injury
•Paralysis of ulnar nerve due to any kind of trauma
•Even some daily activities like: cycling, desk job (elbow leaning), screw tightening
action, etc.

11. PATHOGENESIS
An ulnar claw may follow an ulnar nerve lesion which result in the partial or
complete denervation of the 2 medial LUMBRICALS of the hand.
Their denervation causes these joints to become extended by now unopposed
action of the EXTENSOR DIGITORUM
LUMBRICALS and ITEROSSEI also extend the IP joint of the fingers, their paralysis
result in weakened extension
The combination of hyper extension at the MCP and flexion at the IP joints gives
the hand it’s claw like appearance.

15. COMPLETE CLAW HAND
A hand in Complete claw
hand position will have
the all 4fingers and
thumb hyperextended at
the metacarpophalangeal
(MCP) joints and flexed
at the interphalangeal
(PIP) joints.

17. PREVENTION
•Physical exercise
•Stretching
•Massaging the muscles
•Take a break

18. TREATMENT
Physical Therapy
Hand and finger exercises like squeezing the ball
Surgery
To repair damaged nerve, ligament or muscle
Skin graft in case of scar tissue
Medication
Antibiotics in case of leprosy

19. SURGICAL TREATMENT
Nerve repair or
decompression where
