Chapter 12 wrist/hand & injuries
Gamekeepers thumb
AKA skiers thumb. Rupture of the Thumbs ulnar collateral ligament
Mallet finger
Acclaim of the EPL or EDC tendon from the base DIP joint
Guyon canal
An owner nerve compression at the wrist results in a positive Tinnels sign and guyon on the canal
pamlar radiocarpal ligament
if a person repeatedly falls on an outstretched hand (extended wrist) while snowboarding, they are increased risk for a sprain to which of the following ligments?
emphasis on the "down" position
if the emphasis is eccentric strengthening, how would you instruct your client to pace the exercise?
extension
if you are instructed to work on closed-chain upper extremity activity and you have your patient stand and place her ond on a table with her fingers facing forward and rock forward to touch an object with the other hand, which motion is occuring at the wrist that is on the table?
ulnar nerve
paralysis of the flexor carpi ulnaris muscle could indicate trauma to which nerve?
extension
the PT plan of care directs you to do ISOM strengthening of the wrist extensors in a shortened position. To do this you would place the wrist in which of the following positions?
medial condyle
the bony landmark located on the distal mediaside of the humerus is
flexion
the flexor carpi radialis and flexor carpi ulnaris are agonists in what motion?
radial collateral ligament
the ligament that attaches to the styloid process of the radius and to the scaphoid and trapezium bones is the
radial nerve
the three wrist extensors are innervated by which nerve?
seated with forearm on table, thumb up
when teaching a client strengthening exercises for wrist radial deviation, which of the following is the BEST position to place him in to start the exercise?
flexion and extension of the wrist
when the extensor carpi ulnaris and flexor carpi ulnaris contract simultaneously, which motions are neutralized?
wrist radial deviation
when the flexor carpi radialis and the extesor carpi radialis longus contract simultaneously, which motion results?
extensor carpi ulnaris
which muscle originates on the lateral epicondyle and inserts on the base of the fifth meacrpal?
extensor carpi radialis brevis
which muscle originates on the lateral epicondyle of the humerus and inserts at the base of third metacarpal?
pamaris longus
which muscle originates on the medial epicondyle f the humerus and inserts on the palmar fascia?
flexor carpi radialis
which muscle originates on the medial epicondyle of the humerus and inserts on the base of the second metacarpal?
extensor carpi radialis brevis
which wrist muscle is the direct antagonist of the palmaris longus?
Superficial group forearm compartment
Branch of the anterior compartment included flexor digitorum superficialis flexor carpi ulnaris, flexor carpi radialis, palmaris longus, pronator teres.
Complex regional pain syndrome CRPS
Caused by vasomotor dysfunction. Characterized by pain in edema, discoloration in temperature changes. Sensitive to touch and movement.
Colles fracture
Dinner fork deformity. Fracture of distal radius with radial deviation of the distal fragment. Styloid of ulna maybe Avulsed.
Deep group forearm compartment
FDP, FPL, Pronator quadratus
Froment's sign
Injury to the owner nerve in which the adductor pollicis affected. Have patient hold paper between thumb and index finger. Positive test includes patient unable to hold paper between thumb and webspace of first finger.
DeQuervain's syndrome
Pain May radiate into some and pain with grasping. Information of the EPB sheath and APL sheath. + finkelstein
Trigger finger
Tenosynovitis of the finger flexors due to repetitive forceful gripping. Tendon gliding through the A1 pulley and work with modification to prevent further collagen building
Dupuytran's contracture
Thickening of the fascia under the palm and fingers. May initially be present as tiny nodules under the skin. Causes flexion contractures of the fingers involved
extension
a person needing to stretch the wrist flexors need to put the wrist in what position?
