11/4/2013 Sensory Exam Sensory Exam � What nerves provide sensation to the hand? � Median � Palmar cutaneous branch � Digital nerves to thumb, index, and middle and radial half of ring fingers � Ulnar � Dorsal and palmar cutaneous branches � Digital nerves the small, ulnar half of ring finger � Radial � Sensory branch Sensation: quick and dirty 4

11/4/2013 Motor exam Sensory exam: 2-point discrimination � Median � Normal= 2.5-6 mm � Anterior Interosseous � In kids, see if hand � Recurrent motor branch wrinkles when placed in � Radial water � Posterior Interosseous � Ulnar Motor exam: quick and dirty � Median- thumb palmar abduction (touch tip of small finger) � AIN- OK sign � Ulnar- spread index and long finger apart (peace sign) ) � Radial/PIN- retropulse thumb (palm flat on table, extend thumb) 5

11/4/2013 Specific Tests- FDS/ FDP ER Cases… ER Management The ER Hand Exam � Patient Stabilization � Evaluation for other injuries � Complete but brief assessment � Tetanus, Antibiotics, Irrigation � History � Physical Exam � Imaging 6

11/4/2013 ER History The ER Hand Exam Inspect � Age, Hand Dominance, Occupation � � Document wound location (finger, volar/dorsal, radial/ulnar), size � Mechanism of Injury Sensory Exam � � 2PD � Onset/Location/Duration � Its OK to do a digital block after sensory exam is done!! � Exam Motor exam � � FDP/FDS, extensors, EPL � Range of motion/Rotation Vascular � � Digital Allen’s, Doppler Imaging � Is there a fracture? � Is there a dislocation?

11/4/2013 Choosing the right imaging… Case 1 � Case 2 Case 3 8

11/4/2013 Hand Emergencies � Replants � Revascularizations � Flexor Tenosynovitis � Compartment Syndrome � Acute Carpal Tunnel Syndrome Amputations: Field E&M Field E&M � Control with Save all parts!!! � Direct pressure � Place parts in moist (Ringers) gauze and into a plastic bag � Rare tourniquet (temporary use only) � Bag is placed on ice. NO dry ice! � No clamps � Urgent transfer to ED- Surgical emergency � Elevate arm Wilhelmi BJ, Lee WP, Pagenstert GI, Pagensteert GI, May JW Jr. Replantation in the mutilated hand. Hand Clin. Feb 2003;19(1):89-120 9

11/4/2013 ER Management The bleeding arm that won’t stop � Patient Stabilization � Please LET THE TOURNIQUET DOWN and assess the wound � Evaluation for other injuries � Direct pressure stops bleeding MUCH better � Complete but brief assessment � Tetanus, Antibiotics, Irrigation � History � Physical Exam � Imaging Hand Emergencies: Revascularizations Hand Emergencies: Flexor Tenosynovitis 10

11/4/2013 Hand Emergencies: Compartment Flexor Tenosynovitis: Kanavel Signs Syndrome � Flexed resting position of the digit � Rare entity � Fusiform swelling � Does not include flexor tenosynovitis � Tenderness to � 10 compartments of the hand palpation of the flexor � Dorsal and palmar IO tendon sheath � Thenar, hypothenar � Pain on passive � Adductor digital extension � Carpal Tunnel First Image: Essentials of Hand Surgery 2002 Second Image: Regional Review Course 1998 Acute Carpal Tunnel Syndrome High Pressure Injection Injuries � 1-10% incidence with distal radius fractures � Typically high-energy injury � Peri-lunate, lunate dislocations � Document 2PD prior to reduction and post-reduction � Elevate, check again within 1-hour after reduction 11

11/4/2013 What about the artery that just won’t Conclusions stop bleeding? � Hand Anatomy � Ex: Isolated ulnar or radial artery � Radiographs � In a perfused hand: � Physical Exam � Direct pressure…. Up to 1 hour of compression � Specific ER Cases � Likely a shear injury to vessel � Obtain the correct radiographs � If doesn’t stop, OR to ligate vs repair � Do sensory exam first, then OK to do a block!
