Orthopaedics Flashcards
What can cause spinal cord compression?
Bone displacement
Bone collapse
Disc prolapse
Local tumour or abcess
What is the pattern of distribution of root pain?
Lower motor neurone signs occur at the level of the lesion.
Upper motor neurone signs and sensory changes below the lesion (spastic weakness, brisk reflexes, upgoing planters and loss of co-ordination, joint position, vibration, temperature and pain)
Which tracts lesions affect which sensations on which side of the body?
Dorsal column - light touch, proprioception, vibration - same side as the insult
Spinothalamic - pain and temperature - opposite side 2-3 dermatomes lower than the insult
What does a sharp or dull shoulder pain indicate?
Sharp - capsulitis
Dull - osteroarthrosis
What does pain on movement in the shoulder indicate?
Trauma
Impingement
If young, dislocation
What are the two types of recurrent shoulder dislocation?
Atraumatic
Traumatic
What is an atraumatic recurrent shoulder dislocation?
Atraumatic - no history of trauma, general joint laxity BRAA Bilateral Rehabilitation (treatment) Atraumatic All directions (dislocation direction)
What is a traumatic recurrent shoulder dislocation?
Usually anterior and secondary to trauma (may be mild) BUST Bankard lesion Unidirectional Surgical treatment Traumatic
What is a Bankard lesion?
The capsule is attached to the neck of the scapula but detached from the glenoid labrum
What may cause a rotator cuff tear?
Degeneration
Less commonly a sudden jolt
What are the symptoms of a complete and partial rotator cuff tear?
Complete - limit shoulder abduction to 45-60 degrees
Partial - Painful arc syndrome
There should be full range of passive movement.
Pain is felt at the shoulder tip and upper arm, tenderness at the acromion
How would you investigate a rotator cuff tear?
US, MRI or arthrography reveals communication between joint capsule and subacromial bursa
How would you treat a rotator cuff tear?
Tendon repair may be successful, particularly if done early
What is painful arc syndrome?
Pain on abduction between 45 and 160 degrees.
What are the causes of pain on abduction?
Supraspinatus tendinitis
Calcifying tendinitis
Acromioclavicular joint osteoarthritis
