Be familiar with the nuero anatomy of the upper extremity

Cranial nerves – remember they are contra lateral

Dermatomes – sensory innervation to the upper extremity

If it is intact distal, it is intact proximal. Start distal and work proximal

Brachial Plexus – 11 min

Latisimus dorsi is the ladder climbing muscle

Subscapular – don’t let them pull their hands off their belly

Supraspinatus – starts abduction until the deltoid takes over.

Hornblower test – teres minor

Ulnar nerve (C7/C8-T1)

Median Nerve (C5-C8, T1) tip of fingers, the palm of the hand

Anterior Interosseous Nerve (AIN) 22 min

Radial nerve – extension nerve (C5-T1)

Posterior interosseous nerve – supinator

Most of the extensors

Nerve Entrapment -24 min

When nerves get entrapped they get irritated.

IF YOU CATCH THEM EARLY YOU CAN PREVENT THE NERVE DESTRUCTION PROGRESSION.

If they are having weakness then we need to really push to have that person looked at

Median nerve entrapment

Pronator syndrome is similar to carpal tunnel syndrome.

Carpal tunnel – positive tinels or phalens

Pronator teres syndrome.

Do not be afraid to ask your athlete to provide copies of imaging and reports.

Case #1

16-year-old football player who presents with bilateral hand pain. Pushed from behind during a game and landed face down with his hands in front of his body.

During further questioning of his hands symptoms he states that both of his middle fingers were tingling.

Due to the fact that the patient is experiencing bilateral symptoms, you must go to the source in which would be the spine (C7 nerve)

Ulnar nerve splits the 4th digit.

If you have someone who presents with tingling and numbness on the inner aspect of the hand you know that is C8.

Radial nerve does not go to the tip of the fingers.

Case #2

Saddle bronc rider came off his horse and landed on his head. He walked out of the arena and did not complain of neck, head, or arm symptoms. After driving from Colorado to Texas he went to the sports medicine room stating that he had started to experience bilateral middle finger tingling sensations.

Worse thing to do when you have bilateral symptoms, trauma, and numbness and tingling would be to compress the neck.

Range of motion, neurological testing, and gentle palpation are appropriate to perform in the exam. Orthopedic testing would not be appropriate for this exam.

During exam in both case 1 and 2:

Flexion/extension movements caused finger sensations.

Palpation produced “unusual neck pain” at this point your exam is done

Both cases were referred for immediate cervical xrays.

Case #1 Xray findings: Flexion tear drop fracture of the C5 vertebral body with grade 1-11 retrolisthesis of C5 and C6.

Both of them had surgery the next day.
