Study Notes

Hand Occupational Therapy

Hand Occupational Therapy focuses on the anatomy, function, and clinical conditions of the hand.

Hand Anatomy

Hand structures are categorized into bones, joints, ligaments, tendons, muscles, nerves, and blood vessels.

Hand Function

The hand is described by its range of motions, including wrist extension, flexion, ulnar deviation, radial deviation, finger extension, flexion, abduction, adduction, thumb extension, flexion, abduction, adduction, and opposition.
Various hand grasp types, such as hook, cylinder, spherical, digital, and lateral prehension, are also noted.

Clinical Conditions

Clinical implications cover several hand conditions:
- DeQuervain's stenosing tenosynovitis: Irritation, or inflammation, in a tendon sheath affecting the tendons of the thumb
- Hand Fractures: Bone breaks affecting the hand (shaft, articular, or comminuted fractures) with diverse treatment options (casts, braces, internal/external fixation).
- Trigger finger: Inflammation of the tendon sheath that restricts movement of a finger.
- Carpal Tunnel Syndrome: Nerve compression in the wrist, causing pain, numbness, and tingling in the hand.
- Mallet Finger: Injury to the tendon in the fingertip, preventing straightening of the finger
- Boutonnière Deformity: Damaged extensor tendon, resulting in a characteristic bent finger appearance.
- Dupuytren's Contracture: Thickening of the fascia in the palm, pulling fingers toward the palm.
- Sprains: Injuries to the ligaments surrounding joints in the hand, particularly the thumb (skier's thumb).
Illustrations and anatomical diagrams of different conditions and treatments also exist.
The 27 bones of the wrist and hand are listed and categorized (carpals, metacarpals, phalanges).
