Varus/Valgus Stress Tests § The varus test (see text Figure 208) applies forces laterally at the elbow, medially at the wrist. The valgus test (see text Figure 20 -9) is exactly the opposite. Copyright © 2004 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 5
Scaphoid Fracture Test § The anatomical snuff box is where pressure is exerted over the scaphoid bone. A pain response indicates the presence of a fracture. Copyright © 2004 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 6
Gamekeeper’s Thumb Test § The first metacarpal is stabilized while thumb is passively abducted. Taping can keep the thumb from moving laterally. Copyright © 2004 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 7
Collateral Ligament Test § The PIP joint is gently stressed in a varus direction, then the valgus direction. Pain and/or excessive laxity indicates injury. Copyright © 2004 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 8
Finkelstein’s Test § This tests for de. Quervain’s tenosynovitis. With the thumb within a fist, move the wrist into ulnar deviation. Pain on the radial side is a positive sign. Copyright © 2004 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 9
Tinel’s Sign § Tap a reflex hammer on the carpal tunnel. Tingling or shooting pain in the palm, thumb, index finger, and often the long finger indicates carpal tunnel syndrome. Copyright © 2004 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 10
Phalan’s Test § Hold the position (see text Figure 20 -27) figure for 60 seconds or less. Tingling or shooting pain in the palm, thumb, index, and long fingers indicates carpal tunnel syndrome. Copyright © 2004 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 11
Modified Phalan’s Test § Holding the position for 60 seconds produces tingling or shooting pain in the median nerve branches of the hand with carpal tunnel syndrome. (See text Figure 20 -28. ) Copyright © 2004 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 12
Elbow/Forearm Nerve Injuries § Injury to the three nerves of the elbow and forearm produces different effects. Copyright © 2004 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 13
Ulnar Nerve § Weakness of wrist flexion and ulnar deviation § Flexion loss of DIP joints of the little and ring fingers § Loss of flexion and extension of fingers § Inability to abduct or adduct fingers § Inability to adduct thumb Copyright © 2004 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 14
Median Nerve § Weakness with flexion and radial deviation § Loss of pronation § Loss of thumb opposition § Loss of flexion at MCP joints Copyright © 2004 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 15
Radial Nerve § Loss of wrist extension and supination § Loss of extension at MCP joints § Inability to extend abduct the thumb § Loss of triceps reflex § Weakness of elbow flexion § Ulnar and radial deviation Copyright © 2004 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 16
Wrist Strengthening § These exercises are used to strengthen the wrist after a wrist or hand injury has healed. Copyright © 2004 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 17
Wrist Flexion § Use weights and a padded bench to strengthen the forearm flexor muscles. Copyright © 2004 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 18
