True or False
In medial epicondylitis wrist flexion and pronation is limited by pain
True
Is the history and physical exam enough to diagnose medial/lateral epicondylitis?
Yes
What imaging may be warranted in cases of medial/lateral epicondylitis not responding to conservative management?
Ultrasound/MRI
Are plain radiographs needed in patients with elbow pain and no history of trauma?
Nope
What is the treatment for Medial/lateral epicondylitis?
- LLD
a. limit repetitive activity - NSAIDS
- Tennis elbow strap for comfort
- Pain free stretching and forearm strengthening
- PT consult if conservative management fails
- Ortho consult if no improvement
- Steroid injections
What is located superficially on the extensor side of the elbow making it susceptible to irritation and inflammation?
Olecranon Bursa
What disease process of the elbow may occur secondary to trauma, inflammation, or infection?
Olecranon Bursitis
Can rheumatoid arthritis (RA), gout or other systemic inflammatory processes cause Olecranon Bursitis?
Yes
True or False
Olecranon bursitis
Elbow flexion and extension may be limited by pain
……Yes
What diagnostic tests may be required for a patient with olecranon bursitis?
- aspiration (may be diagnostic and therapeutic)
a. test aspirate for WBC count, crystals, gram stain, and culture - X-ray to rule out fracture of olecranon process
Light duty for patients with olecranon bursitis should be focused on activity modification to include avoiding what?
hyperflexion against hard surfaces
What is the treatment for mild cases of olecranon bursitis?
- NSAIDS
- Pressure wraps
- Ice
What is the treatment for moderate to severe cases of olecranon bursitis?
- aspiration of fluid
2. refer to ortho for evaluation
What are the more common forms of nerve compression syndrome of the upper extremities?
- cubital tunnel syndrome
- median nerve compression
a. occurs in the wrist/hand (carpal tunnel)
What are the less common forms of nerve compression syndrome of the upper extremities?
- Posterior interosseous nerve compression
- Pronator syndrome
- Radial tunnel syndrome
Cubital tunnel syndrome is caused by the compression of what nerve?
Ulnar nerve
Compression of the ulnar nerve is second only to what as a source of nerve entrapment in the upper extremities?
Carpal tunnel syndrome
True or False
Cubital tunnel syndrome
The most common site for nerve compression is where the ulnar nerve passes in the groove on the posterior aspect of the medial epicondyle (cubital tunnel)
True
These are all potential causes of what nerve compression syndrome?
- direct blow to the cubital tunnel
- nerve stretched from flexed elbow for prolonged periods of time
- Cubitus valgus (carrying angle greater than 10 degrees)
- Osteophytes or scar tissue
Cubital tunnel syndrome
A patient experiencing the following symptoms may have what form of nerve compression of the upper extremities?
- numbness/tingling of the 4th and 5th digits
- elbow pain/ache
- may radiate proximally to shoulder and neck
- activities of daily living (ADL) such as opening jars or turning keys in doors are late signs
- intrinsic muscle atrophy implies nerve compression for months
Ulnar nerve compression (cubital tunnel syndrome)
Physical exam: Ulnar nerve compression
Visual exam is usually unremarkable, but a carrying angle greater than ___ degrees may be aggravating findings for ulnar nerve neuritis; and visible muscle wasting implies ulnar nerve compression of ____ to ____ in duration
- 10 degrees.
2. several months to years
Ulnar nerve compression
Vibration and light touch will be affected in the ____ digit and the ulnar half of the ___ digit
- 5th digit
2. 4th digit
True or False
Ulnar nerve compression
Two point discrimination will be affected with progressive nerve degeneration
True
What special test would be used to identify ulnar nerve compression?
Tinnel sign: firm percussion over the ulnar nerve in the ulnar groove over the cubital tunnel
Positive if it reproduces the symptoms
Nerve compression syndrome
Electromyographic/nerve conduction velocity(EMG/NCV) study with velocity reduction of ____% or more suggests ulnar nerve compression
30%
When are radiographs indicated for cubital tunnel syndrome?
history of elbow trauma
What is the treatment for Ulnar Nerve Compression?
- Limiting elbow flexion and direct pressure on the ulnar nerve is the MOST IMPORTANT STEP IN TREATMENT
