What is the treatment of choice for the majority of clavicle fractures?
A simple arm sling is the treatment of choice. A figure 8 splint is not indicated or recommended anymore.
When does a clavicle fracture require surgical correction?
Most will heal well without surgical correction. Surgery is indicated when there is complete displacement.

Nurse maid elbow. Reduction will cause immediate pain relief.
What is the most common mechanism for schaphoid fractures?
FOOSH: Fall on outstretched hand.
What anatomical location needs to be palpated when evaluating a schaphoid frac- ture?
The anatomic snuffbox will elicit pain when palpated. Generalized wrist pain will be noted. Swelling may or may not be present.
What is the major complication associated with an untreated scaphoid fracture?
The main worry is avascular necrosis. Patients with a suspicion for fracture should be kept in a thumb spica splint until this can reliably be excluded.

NSAIDs and rest! This is simply an overuse syndrome. Stop using it and the symptoms resolve.
What digits are affected in patients with carpal tunnel syndrome?
The first 3 digits and the radial half of the 4th digit will be affected.
When is surgery indicated for a boxers fracture?
Surgery is indicated if there is any degree of rotation. Surgery is also indicated if neurovascular impairment or an open fracture is seen. Psuedoclawing can occur at 30 degrees of angulation and these should be reduced and placed in an ulnar gutter splint.
What is a finklestein test and when will it yield a positive result?

Patients with spinal stenosis will notice relief of symptoms with what type of position?
They will present with the shopping cart sign: relief with forward bending.
What X-ray views are needed when evaluating avascular necrosis?
All patients should be evaluated with a frog leg lateral view.
