Week 1 Lecture Flashcards
List the muscles in the superficial compartment of the arm (5)
- Pronator teres
- Flexor Carpi Radialis
- Palmaris Longus
- Flexor Carpi Ulnaris
- Flexor Digitorum Superficialis
List the muscles in the deep layer of the forearm (3)
- Flexor Pollicus Longus
- Flexor Digitorum Profundus
- Pronator Quadratus
What is ‘Trigger Finger’
Insidious onset of a Nodule in flexor tendon - this nodule gets caught as it passes through the pulley (fibrous bands) and prevents extension
At what ‘Pulley” does trigger finger commonly occur?
A1 - at the MCP
List four common wrist/forearm injuries/conditions related to the extensor tendon compartment
- De Quervain’s Tenosynovitis
- EPL rupture
- EDM Rupture
- Subluxation of ECU
What is extensor expansion
The input of the Interossei muscles, which aids the ED in middle and distal phalanx extension
What two muscle tendons are involved in De Quervains Tenosynovitis
- EPB
2. APL
Two Special tests for De Quervains Tenosynovitis
- Finklesteins
2. WHAT
3 special tests for carpal tunnel syndrome
- Tinels sign
- Phalens test
- Reverse Phalens test
Special test for the ulnar nerve
Fromonts sign
What is a Galleazi fracture
An isolated fracture of the junction of the distal or middle third of the radius, with associated subluxation or dislocation if the distal radio-ulna joint
Minimum functional ROM for i) flexion ii) extension
i) 10 degrees
ii) 35 degrees
Optimal ROM for i) flexion ii) extension
i) 50-55
ii) 60
Optimal ROM for i) UD ii) RD
i) 40 degrees
ii) 17 degrees
List 4 common acute injuries of the wrist
- distal radial fracture
- Scaphoid fracture
- Wrist ligament sprain
- Scapholunate injury
What does a Terry Thomas sign on an X-ray indicate
Scapholunate dissociation
What is a colles fracture?
complete # radius with dorsal displacement of the distal fragment
List 5 clinical signs of a Scaphoid #
- report of FOOSH
- Snuff box tenderness
- Poor grip
- swelling
- painful RD
What two movements are especially problematic for someone with scapholunate dissociation
extension
UD
List 4 clinical signs of a TFCC tear
- MOI; compression and UD
- Pain with resisted UD
- clicking
- reduced grip strength
2 tests for TFCC tear
- Press test
2. Compression test
What is skiers thumb
Ulnar collateral ligament of the 1st MCP joint - sprain or tear
5 common causes of gradual onset wrist pain
- De quervains tenosynovitis
- Tendinopathies
- Carpal tunnel syndrome
- OA
- TFCC
What 4 muscular tendons are involved in intersection syndrome
- APL
- EPB
- ECRL
- ECRB
Pins and needles in the 4th and 5th digit may be indicative of what pathology
Guyons canal syndrome
Where is OA most likely in the hand/wrist/fingers?
1st CMC
Phalen’s test is performed in wrist…?
sustained wrist flexion
Reverse phalen’s test is performed in wrist…?
sustained wrist hyperextension
