Wrist/Hand Disorders

What can be a complication of severely displaced distal radius fractures?

• Ulnar nerve compression

• Median nerve compression

• Radial nerve compression

• Tibial nerve compression

What type of X-ray finding is associated with a Colles' Fracture?

• Volar displacement/angulation of the distal radius fragment

• Dorsal displacement/angulation of the distal radius fragment

• No displacement, only angulation of the distal radius fragment

• Medial displacement/angulation of the distal radius fragment

What is the characteristic displacement/angulation in a Smith's Fracture?

• Dorsal displacement/angulation of the distal radius fragment

• Medial displacement/angulation of the distal radius fragment

• Lateral displacement/angulation of the distal radius fragment

• Palmar/volar displacement/angulation of the distal radius fragment

What is the most common type of carpal fracture?

• Lunate fracture

• Capitate fracture

• Scaphoid (navicular) fracture

• Hamate fracture

How does the blood supply to the scaphoid bone travel?

• From proximal end to distal end

• From distal end to proximal end

• From medial end to lateral end

• From lateral end to medial end

What risk is increased when a scaphoid fracture disrupts the blood supply?

• Risk of infection

• Risk of arthritis

• Risk of nonunion

• Risk of carpal tunnel syndrome

What is the initial treatment for a scaphoid fracture when x-rays are negative but suspicion for fracture is still high?

• Immediate surgical intervention

• Treat like a sprain with compression bandage

• Treat like a fracture with thumb spica splint and repeat x-ray in 1 week

• Cast immobilization for 3 weeks without further imaging

What is a possible next step in diagnosis if a lunate fracture is not visible on an X-ray?

• CT scan

• Ultrasound

• Blood test

• Physical therapy

What is a Boxer's fracture?

• Fracture of the 1st or 2nd metacarpals

• Fracture of the 4th or 5th metacarpals

• Fracture of the wrist bones

• Fracture of the phalanges

What antibiotic is suggested for a Boxer's fracture when there is a punch to teeth resulting in an open wound?

• Cephalexin

• Amoxicillin/Clavulanate

• Metronidazole

• Doxycycline
