What is the pathomnemonic sign for DeQuervain?
Positive Finklestein test
Describe the Finklestein test
Quick ulnar deviation of the wrist by grabbing onto the patients thumb
What is the specificity of the Finklestein in diagnosing DeQuervain
100%
Which muscles are involved in interssection syndrome
Abductor pollicis longus and extensor pollicis brevis
You see a 20 y/o professional skiier with wrist swelling, radial-sided pain and crepitus of the distal forearm. His pain is exacerbated with wrist flexion and extension and you notice intense tenderness about 4cm proximal to the radiocarpal joint. What is your most likely diagnosis?
Interssection syndrome
- distal forearm pain
- Increased with wrist extension
- possible crepitus
- 4cm proximal to radiocarpal joint
- visible swelling

What imaging modality would you order for a patient who you suspect has an interssection syndrome?
Ultrasound
A 45 y/o female presents with radial sided pain.Her pain is worsened with movements of the thumb. On exam you notice crepitus and tenderness over the radial syloid. What is your most likely diagnosis?
DeQuervain Tenosynovitis
- Inflammation of 1st compartment
- Pain with thumb movements
- Specific tests: Finkelstein test, Eichoff test
A 82 y/o female presents to your office complaining of radial sided wrist pain. She says that the pain is worst when grasping objects and opening jars. On exam you notice a dorsoradial prominence and adduction of the thumb metacarpal. What is your most likely diagnosis?
Thumb CMC arthritis
- most common site of symptomatic arthritis of the hand
- throbbing pain radial hand/wrist
- thenar pain
- increased symptoms with pinch, grasp or twisting
- shoulder sign: dorsoradial prominence of thumb MC base
- Flexion and adduction of thumb metacarpal
- Specific tests: grind, adduction stress, extension, lever test
What is the grind grind test?
Specific to CMC arthritis
Description: Compression of metacarpal on trapezium and rotating the metacarpal.
What is the adduction stress test?
Specific test for CMC arthritis
Description: pressure is placed on dorsal aspect of metacarpal and the thumb metacarpal is brought paralled to the index with adduction
