NEW ALL PATHOLOGIES FOR MS 1 FINAL EXAM
WITH Q&A NEWLY MODIFIED EXAM!!
What goes through the Tunnel of Guyon?
ulnar nerve
Where is the tunnel of Guyon?
between the hook of hamate (radial border) and pisiform (ulnar border)
What are different ways that the tunnel of Guyon can become irritate or injured?
-sustained pressure (handwriting, biking)
-repetitive gripping action of 4th or 5th digits
-Trauma
-space occupying lesions (ganglion or aneurysm of ulnar nerve)
What are the clinical findings with an irritated tunnel of Guyon?
-paresthesia in the little finger and ulnar side of hand
-atrophy of hypothenar eminence and intrinsic (partial claw hand posture) -(+) tinels sign at
tunnel of Guyon
What are the common tendinitis/tenosynovitis of the wrist and hand?
-wrist/finger extensors
Page 1 of 145
,-wrist/finger flexors
-trigger finger
-De Quervain's tenosynovitis
What is Tendonitis? inflammation of the tendon or tendon-muscle attachment
-overuse syndromes
What is tenosynovitis?
inflammation of the tendon sheath
-common with inflammatory rheumatic diagnosis, DM , and hypothyroidism conditions
(deeper inflammatory problems)
What are the common sites of tendonitis and tenosynovitis of compartment 2?
-intersection of ECRL and ECRB (compartment 2) (radial wrist extensors) as they cross
under APL and EPB (compartment 1) pain site is different the DeQuervain
What is the common site for tendonitis and tenosynovitis for the EPL?
-common with RA
-pain, swelling, and crepitus at Lister's tubercle
What is the common site for tendonitis and tenosynovitis for the EI?
-hypertrophy or swelling from repetitive exercise
Page 2 of 145
,-increased pain with resistance to active index finger extension with the wrist held in flexion
What is the common sites for tendonitis and tenosynovitis for the ECU? aggravated by
supination and ulnar deviation
-repetitive motions
What is the common sites for tendonitis and tenosynovitis for the FCU? aggravated by wrist
flexion and ulnar deviation
-repetitive motions
What is a Reverse Colles (Smith) fracture? complete fracture of distal radius with anterior
displacement of distal fragment -from FOOSH injury with wrist flexed
What is the most common wrist injury for all age groups?
distal radius fractures
-typically from a FOOSH
What is the common loss of ROM following a distal radius fracture? full
pronation/supination of forearm
Page 3 of 145
, What is a Barton fracture? dorsal or volar distal radius fracture resulting in a wrist
subluxation
How can a Barton's fracture occur?
direct or aggressive injury to the wrist or a sudden pronation of the distal forearm on a fixed
wrist
-must reduce scaphoid to correct position
What is a Buckle fracture?
an incomplete, undisplaced fracture commonly seen in children
What do we have to consider when we see a buckle fracture?
possibility of abuse should be considered for children
What is the most common fractured carpal bone? scaphoid fracture
What fracture is most commonly missed on X-rays?
scaphoid fracture because it may not show up
-sometimes require bone scan or CT scan
