When making a tight fist, which muscle group is most active?
Flexors
Extensors
Supinators
Pronators
Differentiate between a sprain and a fracture in the wrist. What structure is injured in each?
Jersey Finger typically involves a flexor tendon tear, preventing the individual from fully flexing the fingertip.
True
False
An athlete jams their finger while catching a ball. Name one common sign that might indicate a jammed finger versus a fracture.
Which muscle rotates the forearm from palm-down to palm-up?
Pronator Teres

Extensor Carpi Ulnaris
Why might the thumb require different treatment than the other fingers in cases of sprains or fractures?
Which of the following injuries is most commonly associated with punching or striking an object incorrectly?
Mallet Finger
Boxer’s Fracture
Jersey Finger
Distal Radius Fracture
A student falls on an outstretched hand and complains of severe wrist pain: Suggest one special test to help determine if there is a ligament sprain vs. a bone fracture.
Mallet Finger is typically caused by damage to the:
Extensor tendon at the distal phalanx
Flexor tendon at the distal phalanx
Thumb’s collateral ligament
Forearm pronators
Which muscle primarily rotates the forearm palm-down (pronation)?
Biceps Brachii
Pronator Teres
Supinator
Extensor Carpi Radialis Longus
Describe a simple test you could do to evaluate the strength of the wrist extensors.
Which muscle is the primary supinator besides the biceps when the elbow is extended?
Supinator
Pronator Quadratus
Flexor Carpi Ulnaris
Extensor Carpi Ulnaris
An individual complains of wrist pain only when extending their wrist against resistance: Name one muscle or tendon group that might be injured.
Which statement is true about Boxer’s Fracture?
It typically affects the 2nd metacarpal.
It involves a fracture of the 5th metacarpal
It usually results from hyperextension of the DIP joint.
It’s another term for a jammed finger.
Provide two signs that might indicate a severe wrist sprain.
“Mallet Finger” often presents as:
Inability to extend the fingertip (DIP joint)
Inability to flex the MCP joint
Fracture of the 5th metacarpal
Tear in the thumb’s UCL
After repetitive backhand strokes in tennis, a player experiences forearm pain on the lateral side near the elbow. Which wrist muscle group is likely overworked?
If someone can’t fully flex their fingertip at the distal joint, which common tendon injury is suspected?
Differentiate Jersey Finger from Mallet Finger in terms of which tendon is affected (flexor or extensor) and the resulting motion loss.
A patient struggles to extend their wrist after a fall: Mention one test or observation you might do to determine if it’s a tendon injury vs. a sprain.
Which muscle is a key wrist extensor?
Flexor Carpi Radialis
Flexor Pollicis Longus
Extensor Carpi Radialis Longus
Brachialis
Why do flexors and extensors both engage while typing on a keyboard?
A wrist sprain primarily involves:
A tear in the muscle belly
A break in the bone
Ligament damage
Nerve compression
Provide one sign that indicates a thumb sprain might need more urgent care than a simple finger sprain.
Which muscle group helps with stabilizing the wrist when the fingers are flexed to grip an object?
Pronators
Extensors
Supinators
Hip flexors
You’re checking for a possible distal radius fracture after a fall: Describe one test or sign indicating a fracture rather than a sprain.
A student can’t fully extend their ring finger at the DIP joint. Which common finger injury might they have?
A sprain in the wrist involves injury to the:
Muscle belly in the forearm
Ligaments supporting the wrist joints
Extensor tendons at the elbow
Pronator muscle only

Which muscle is a deep forearm muscle specializing in forearm supination?
Extensor Carpi Radialis Brevis
Supinator
Pronator Teres
Palmaris Longus
Why might a thumb sprain be more debilitating than a similar sprain in the little finger?
