Hand Conditions Quiz

A tear or strain to the ulnar collateral ligament (UCL) in the thumb, often caused by jamming the thumb or forceful bending.

A condition where a thickened tendon sheath in the finger prevents the tendon from gliding smoothly, causing snapping or catching.

A nerve compression disorder that occurs when the median nerve in the wrist is squeezed, causing numbness, tingling, and pain in the hand and fingers.

An injury to the extensor tendon at the tip of a finger, often caused by a forceful bending or impact to the fingertip.

A physical examination maneuver where tapping on the median nerve at the wrist provokes tingling and numbness in the hand, suggesting carpal tunnel syndrome.

A surgical procedure to repair or reconstruct a torn ulnar collateral ligament in the thumb.

A treatment option for carpal tunnel syndrome that involves injecting steroids into the carpal tunnel to reduce swelling around the median nerve.

Treatment for carpal tunnel syndrome and other hand conditions that involves resting the wrist in a neutral position to reduce pressure on the median nerve.

De Quervain's tenosynovitis is a painful condition affecting the tendons of the thumb. It causes irritation and swelling in the sheath that surrounds the tendons as they pass from the wrist to the thumb.

The Finkelstein test is a common way to diagnose De Quervain's tenosynovitis. It involves making a fist with the thumb tucked in and bent towards the little finger. Pain worsens with this movement.

Dupuytren's contracture is a condition that causes thickening of the fascia (tissue beneath the skin) in the palm. This thickening can lead to bands that pull the fingers into the palm.

The main treatment for Dupuytren's contracture is surgery. This is recommended when the bands cause progressive contracture and pull the fingers into the palm.

Thumb sprains occur from injuries like sports or falls, where the thumb is jammed into another player, the ground, or a ball. Symptoms include pain, swelling, and bruising.

The ulnar collateral ligament is the most common ligament to be injured in a thumb sprain. This injury is known as 'skier's thumb' due to its occurrence in skiing falls.

Thumb sprains can be caused by twisting the thumb into an extreme position. This usually occurs due to the force of a fall, impact, or sudden movement.

Treatment for thumb sprains typically involves immobilizing the thumb with a brace or splint to allow the ligament to heal properly.

A condition where the extensor tendon is injured, causing the middle joint of the finger to bend downwards.

The thin tendons on the back of the hand and fingers, responsible for finger extension.

A type of injury to the extensor tendons where they are torn away from the bone, often caused by jamming the finger.

A type of treatment for extensor tendon injuries involving placing the injured finger in a rigid support.

The time required for an extensor tendon injury to fully heal, typically ranging from 4 to 8 weeks.

Cuts that split the extensor tendon may require stitches, but tears caused by jamming injuries are often treated with splints.

The location of extensor tendons on the back of the hand and fingers makes them vulnerable to injury even by minor cuts.

Splints that have no moving parts and are primarily used to provide support and immobilization.

Splints that use devices like rubber bands, velcro strips, or springs to control joint movement.

Splints are used to prevent deformities by supporting weakened muscles, often after nerve injuries.

Splints can be used to correct existing deformities, such as a bent finger or a crooked wrist.

Splints can provide directional control and be used as a base for attaching other devices to improve hand function.

The area at the base of the fingernail, where the nail is attached to the skin.

The middle joint of the finger, between the middle and top bones.

The joint at the tip of the finger, between the top bone and the fingernail.

The joint at the base of the finger, where the finger connects to the hand.

Injuries to the tendons on the back of the hand that extend the fingers, making it difficult to straighten the fingers.

A type of splint used for tendon injuries that allows for some finger movement while protecting the healing tendon.

The area on the finger where the flexor tendons are most commonly injured, between the middle of the middle phalanx and the fingertip.

The area on the finger where the flexor tendons are injured, between the middle of the middle phalanx and the distal palmar crease.

The area on the finger where the flexor tendons are injured, between the distal palmar crease and the edge of the flexor carpal ligament.

The area under the carpal ligament where flexor tendon injuries can occur.

The area proximal to the wrist joint where flexor tendon injuries can occur.

Tough, fibrous rings that guide the tendons and keep them close to the bones, allowing for efficient movement of the joints.
