About This Presentation

Description : Check out this medical PowerPoint presentation titled "Wrist and Hand” by John T. Capo, MD.

This medical PowerPoint presentation is about the wrist and hand, parts of the upper extremity, located between the forearm and the fingers. The wrist joint connects the two bones of the forearm, the radius and ulna, to the eight small carpal bones in the hand. The hand itself consists of the palm (or the metacarpus) and the fingers (or the digits).

The wrist and hand are important for performing a wide range of daily activities, including grasping, holding, typing, writing, and manipulating objects. They are also essential for many sports and hobbies, such as playing musical instruments, drawing, and sports that require gripping or throwing.

Injuries or conditions that affect the wrist and hand can cause pain, weakness, and limited mobility. Common problems include carpal tunnel syndrome, tendonitis, fractures, and arthritis. Treatment options may include rest, physical therapy, medication, splinting, or surgery, depending on the specific condition and severity of symptoms.

Transcript

Slide 1-

Wrist and Hand Wrist is the most complex joints of the body due to the numerous joints combined to create one.
Slide 2-

Wrist and Hand Anatomy Carpal bones- Create a Mnemonic for them. S-L-T-P-T-T-C-H
Slide 3-

Wrist and Hand Anatomy Two rows of bones starting on the thumb side. Scaphoid, lunate, triquetrum, pisiform
Slide 4-

Palpate the Scaphoid You would palpate the scaphoid in the anatomical snuff box.
Slide 5-

Wrist and Hand Anatomy Second row of carpals bones, is more proximal Trapezium, trapezoid, capitate, Hamate.
Slide 6-

Wrist and Hand Anatomy Medial and Lateral epicondyle are where many of the wrist and hand muscles originate.
Slide 7-

Wrist and Hand Anatomy Styloid process- projection at distal end of radius and ulna where the collateral ligaments attach.
Slide 8-

Wrist and Hand Joints Radiocarpal Joint- distal end of the radius and scaphoid, lunate, and triquetrum. There is a radioulnar disk in between the radius and other bones. It is a condyloid joint.
Slide 9-

Wrist and Hand Joints Midcarpal joint- between the two rows of carpal bones. Plane joints that allow gliding motion, but assist with wrist motions.
Slide 10-

Wrist and Hand Joints Carpometacarpal joint- between the distal row of carpal bones and proximal end of the metacarpal bones. Provide more stability than mobility.
Slide 11-

Ligaments of hand Palmar radiocarpal ligament-broad band attaches anterior surface of distal radius and ulna to anterior surface of the proximal carpal bones and the capitate. Limits wrist extension. So repeated falls in extension would injur it.
Slide 12-

Wrist and Hand Injuries Fractures of the Wrist and Hand Finger Fractures Boxer’s Fracture- fracture of 5th metacarpal. Hitting something with fisted hand.
Slide 13-

Wrist and Hand Injuries Fractures of the Wrist and Hand Finger Fractures Scaphoid Fracture- fracture of scaphoid which you call palpate in anatomical snuffbox. Occurs with fall on hand in extension.
Slide 14-

Wrist and Hand Injuries Wrist Fractures Colles’s fracture- fracture of the radius just above the wrist. A result of a fall with wrist extended.
Slide 15-

Tendon Injuries Mallet Finger- hitting something with the tip of a finger and causing the extensor tendon to tear. Jersey Finger- grabbing something and tearing the flexor tendon.
Slide 16-

Tendon Injuries Boutonniere deformity- extensor tendon injury affecting two joints of the finger. It is an injury to the central tendon on top of the finger. It may appear as a “jammed finger” that cannot be extended from the PIP joint. Treatment should be in an extended position so the tendon can heal.
Slide 17-

Dislocations/Subluxations Dislocations occur in the fingers and wrist bones. Point tenderness and swelling, possible deformity. Physician intervention may be necessary.
Slide 18-

Wrist and Hand Muscles Extensor Carpi Ulnaris- superficial muscle that arises from the common extensor tendon on the lateral epicondyle. It runs the medial side of the posterior arm and attaches to the fifth metcarpal. What does it do?
Slide 19-

Wrist and Hand Muscles Flexor carpi radialis- superficial muscle running from the medial epicondyle diagonaly across the anterior forearm to attach to lateral base of second and third metacarpal. What is the motions?
Slide 20-

Wrist and Hand Muscles Palmaris Longus- superficial muscle running down the anterior surface of the forearm from common flexor attachment of medial epicondyle to the midline of the palmar fascia. Missing in 21% of people. Flexor
Slide 21-

Wrist and Hand Muscles Flexor Digitorum superficialis- deep to the wrist flexors and palmaris longus muscle. Starts at the common flexor tendon of medial epicondyle and coranoid process, inserts to the sides of digits 2-5.
Slide 22-

Wrist and Hand Muscles Abductor pollicis brevis- proximal attachment is the scaphoid, trapezium and inserts to the base of the proximal phalange of the thumb.
Slide 23-

Hand Grips Grasps Power grip is when an object needs to be held forcefully and then moved by more proximal muscles. Precision Grip is when an object is manipulated with fingers
Slide 24-

Hand Grips Power grips Cylindrical grip is fingers flexed around an object. Thumb on one side fingers on other, like gripping a hammer or racquet. Spherical grip is fingers and thumb are together around an object. Like grabbing an apple or doorknob.
Slide 25-

Hand Grips Power Grip Hook grip involves the second through fifth fingers flexed around an object in a hooklike manner. Thumb is extended and not involved at all. Only possible grip for someone with no thumb or median nerve ability.
Slide 26-

Hand Grips Precision Grips- Pad to pad Pinch grip is the thumb and one finger gripping Three jaw chuck is holding a pencil, three fingers and thumb.
Slide 27-

Hand Grips Precision Grips Tip to Tip grip Pincer grip is tip of thumb against tip of a finger, like to pick up a coin. Difficult with long fingernails
Slide 28-

Hand Grips Precision Grips Lumbrical grip or plate grip has the MCP and PIP joint flexed and the DIP extended. The thumb opposes and this grip is used to hold something horizontal like a plate. Lumbricals is used they flex the MCP joint.
