Shoulder conditions Flashcards
What is impingement syndrome?
When the tendons of the rotator cuff are compressed in the subacromial space - the rotator cuff tendons insert on the greater tuberosity of the humerus
What can cause impingement syndrome?
Anything that reduces the subacromial space:
- rotator cuff tear that has hooked
- tendonitis (tendon will swell)
- osteoarthritis (osteophytes etc)
How does impingement syndrome present?
Painful arc on abduction (60-120 degrees)
pain radiating to deltoid and upper arm
Positive Hawkins-Kennedy test
How is impingement syndrome managed?
Rest & physio
NSAIDs
Up to 3 subacromial steroid injections
If still not improving - decompression surgery
What is another name for adhesive capsulitis?
Frozen shoulder
What is adhesive capsulitis?
disorder characterised by progressive stiffness and pain in the shoulder which slowly resolves over 18-24 months
Which conditions are people more likely to get adhesive capsulitis in?
Diabetes
Hypercholestereamia
Dupytrens contracture
What is the typical presentation of adhesive capsulitis?
Loss of external rotation
Pain will subside after a few months as stiffness increases, then stiffness begins to thaw after about a year
Management of adhesive capsulitis?
Physio and steroid injections
What is the classic history of a rotator cuff tear?
> 40 year old with pain and weakness following a sudden jerk e.g. holding the rail on the bus and it suddenly stopping
if supraspinatus, infraspinatus or Subscapularis was affected by a rotator cuff injury which movement would be lost?
Supraspinatus = initiation of abduction Infraspinatus = external rotation Subscapularis = internal rotation
What can confirm a rotator cuff tear?
MRI/ultrasound
Management options for rotator cuff tears?
Conservative = physio + steroid injections Surgical = rotator cuff repair +/- subacromial decompression
Which type of shoulder dislocation is most common and which age group is most commonly affected?
Anterior dislocation
Teens-30 yrs
What is the relation between age of first shoulder dislocation and chances of recurrent dislocations?
The younger you are the more likely you are to dislocate it again - 80% if under 20 and 20% if under 30
