Colles' fracture

What is it called when both bones in the forearm are broken?

Colles' fracture

Aseptic Necrosis in the wrist

Dislocated Intra-phalangeal joint

Deformed finger. Refer for xray.

Colle's Fracture

Distal fx of Radius and Ulna

Mallet Finger

Which of these best describe boutonniere deformity?

PIP joint flexion and DIP joint hyperextension

Jersey Finger

Torn distal flexor tendon from finger getting caught in jersey.

Which injury in the wrist involves compression of the median nerve resulting in tingling and numbness in the fingers and thumb?

carpal tunnel syndrome

Tendinitis that affects the abductor pollicis longus and extensor pollicis brevis is commonly known as

Which tendons of the thumb are involved in De Quervains' syndrome?

extensor pollicis brevis & abductor pollicis longus

What is the most common injury mechanism for wrist injuries?

falling on an outstretched arm

Boxers Fracture

fracture of the 5th metacarpal

The carpal bone most likely to fracture due to compression or contusion is called the

hamate

What is the common treatment for a gamekeeper's thumb injury?

When a flexor tendon is torn from the distal phalanx, resulting in an inability to straighten the finger, it is called

A sprain to the medial collateral ligament of the thumb is called

skier's thumb or gamekeeper's thumb

Dequervain's syndrome (tenosynovitis)

This geometric structure, abbreviated TFCC, is located on the medial aspect of the wrist, between the ulna and carpal bones. It serves to cushion this area, but it is sometimes injured, especially with wrist hyperextension injuries.

triangular fibrocartilage complex

The most commonly sprained ligament in the thumb is called the
