Sensory Exam

What nerves provide sensation to the hand?

Sensory Exam

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

Sensory exam: 2-point discrimination

Normal= 2.5-6 mm In kids, see if hand

wrinkles when placed in water

Motor exam

Median

Anterior Interosseous Recurrent motor branch

Radial

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)

)

Specific Tests- FDS/ FDP ER Cases… ER Management

Patient Stabilization Evaluation for other injuries Complete but brief assessment Tetanus, Antibiotics, Irrigation History Physical Exam Imaging

ER History

Age, Hand Dominance, Occupation Mechanism of Injury Onset/Location/Duration Exam

The ER Hand Exam

  • Inspect

Document wound location (finger, volar/dorsal, radial/ulnar), size

  • Sensory Exam

2PD Its OK to do a digital block after sensory exam is done!!

  • Motor exam

FDP/FDS, extensors, EPL Range of motion/Rotation

  • Vascular

Digital Allen’s, Doppler

Imaging

Is there a fracture? Is there a dislocation?

Hand Emergencies

Replants Revascularizations Flexor Tenosynovitis Compartment Syndrome Acute Carpal Tunnel Syndrome

Amputations: Field E&M

Control with

Direct pressure Rare tourniquet

(temporary use only)

No clamps Elevate arm

Field E&M

Save all parts!!!

Place parts in moist (Ringers) gauze and into a

plastic bag

Bag is placed on ice. NO dry ice! Urgent transfer to ED- Surgical emergency

The bleeding arm that won’t stop

Please LET THE TOURNIQUET DOWN and

assess the wound

Direct pressure stops bleeding MUCH better

Hand Emergencies: Revascularizations

Hand Emergencies: Flexor Tenosynovitis

Flexor Tenosynovitis: Kanavel Signs

Flexed resting position of the digit Fusiform swelling Tenderness to

palpation of the flexor tendon sheath

Pain on passive

digital extension

First Image: Essentials of Hand Surgery 2002 Second Image: Regional Review Course 1998

Hand Emergencies: Compartment Syndrome

Rare entity Does not include flexor tenosynovitis 10 compartments of the hand

Dorsal and palmar IO Thenar, hypothenar Adductor Carpal Tunnel

Acute Carpal Tunnel Syndrome

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

High Pressure Injection Injuries

What about the artery that just won’t stop bleeding?

Ex: Isolated ulnar or radial artery In a perfused hand:

Direct pressure…. Up to 1 hour of compression Likely a shear injury to vessel If doesn’t stop, OR to ligate vs repair

Conclusions

Hand Anatomy Radiographs Physical Exam Specific ER Cases

Obtain the correct radiographs Do sensory exam first, then OK to do a block!
