Study of Nerve Repair and Reconstruction Associated With Major Extremity Trauma

Inclusion Criteria:

1. Ages 18-65

2. Sustained a peripheral nerve injury (including iatrogenic injuries and partial nerve
injuries) resulting from upper extremity trauma meeting the following criteria:

1. Involves injury or dysfunction to motor, or motor and sensory function of the
axillary, radial, median, ulnar, or musculocutaneous nerve with injury localized
distal to the brachial plexus cord level and proximal to the distal flexion
crease of the wrist

2. Involves a "mixed" nerve segment (i.e. involves a location of any of the above
specified nerves that can be expected to have both sensory and motor axons
present) but does not include sensory only distal terminations of the same
nerves.

3. Receiving surgical treatment (i.e. exploration, neurolysis, repair or reconstruction,
nerve or tendon transfer) within 6 months of the initial injury.

Exclusion Criteria:

1. Injuries to the brachial plexus roots, trunks, divisions and cords

2. Injuries to the nerves distal to the distal flexion crease of the wrist

3. Injuries that involve a distal extension of the parent nerve that is considered
sensory only (superficial radial nerve, lateral ante brachial cutaneous nerve, etc)

4. Previous motor or sensory deficit prior to injury (e.g. resulting from trauma, stroke,
muscular, neurologic, neuromuscular disorder, etc.)

5. Documented psychiatric disorder that limits ability to consent and maintain follow-up

6. Unable to speak either English or Spanish

7. Severe problems with maintaining follow up (e.g patients who are prisoners or homeless
at time of injury or who are intellectually challenged without adequate family
support).
