Anatomy and Nerves
Most flexor muscles of the forearm are innervated by this nerve.
What is the median nerve?
This is the most common wrist injury caused by abnormal forced movement.
What is a wrist sprain?
This test involves tapping over the transverse carpal ligament.
What is Tinel’s sign?
This common mechanism (falling on an outstretched hand) is abbreviated as this.
What is FOOSH?
Pain, swelling, possible loss of ROM, and hematoma are classic signs of this injury.
What is a contusion?
These two arteries supply blood to the forearm and hand.
What are the radial and ulnar arteries?
Compression of the median nerve in the wrist results in this condition.
What is carpal tunnel syndrome?
This test requires holding wrist flexion for ~1 minute to reproduce symptoms.
What is Phalen’s test?
A Colles fracture is typically caused by this mechanism.
What is a fall on an outstretched hand with hyperextension?
Tingling and paresthesia in the hand suggest involvement of this.
What is nerve compression?
This nerve controls most extensor muscles of the forearm.
What is the radial nerve?
This fracture occurs at the distal radius and shows a “dinner fork deformity.”
What is a Colles fracture?
This test is used to diagnose deQuervain’s syndrome.
What is Finkelstein’s test?
A hamate fracture commonly occurs when an athlete is doing this.
What is holding an implement (like a bat or racket)?
Severe pain in the anatomical snuffbox indicates this injury.
What is a scaphoid fracture?
These three major nerves supply the hand.
What are the median, ulnar, and radial nerves?
This condition involves inflammation of tendon sheaths due to overuse.
What is tenosynovitis?
This test assesses circulation by occluding radial and ulnar arteries.
What is the Allen’s test?
This injury results from violent twisting and affects the ulnar side of the wrist.
What is a TFCC injury (triangular fibrocartilage complex)?
A claw hand deformity is associated with damage to these nerves.
What are the ulnar and median nerves?
The carpals are wedged between the radius and ulna in this deformity.
What is Madelung deformity?
This condition involves loss of blood supply to the lunate bone.
What is Kienböck’s disease?
This test assesses scapholunate instability by applying pressure to the scaphoid.
What is the Watson test?
This injury occurs from repetitive pulling of wrist flexors like flexor carpi radialis.
What is tendinitis?
Snapping, locking, and a palpable nodule in the finger indicate this condition.
What is trigger finger?
