Shoulder pathologies Flashcards
Impingement syndrome - definition
Tendons of the rotator cuff become inflammed as they are compressed in the tight subacromial space during movement
Impingement syndrome - which rotator cuff muscle is most commonly affected?
Supraspinatous
Impingement syndrome - epidemiology
age
Middle aged
Impingement syndrome - causes
Rotator cuff tear
Tendonitis
Osteophytes from AC joint
Subacromial bursitis
Impingement syndrome - clinical features
Pain originating in the subacromial space which radiates to the deltoid and upper arm
Deep pain
Pain felt when arm is abducted
Impingement syndrome - examination
Look:
contour, muscle wasting, deformity, scapula position
Feel:
Tenderness
Move:
Pain on abduction
- this pain subsides once they abduct their arm pst a certain height
Impingement syndrome - painful arc angle
60-120 degrees of abduction
as inflammed area of supraspinatus tendon passes through the subacromial space
Impingement syndrome - investigations
X-ray
- fluffy dots floating outside (calcium)
US
MRI
Impingement syndrome - management
NSAIDs
Analgesia
Physio
Subacromial injection (can administer up to 3)
Severe:
subacromial decompression surgery (wait at least 6 months first)
Adhesive capsulitis - definition
Frozen shoulder. Inflammation of the capsule and glenohumeral ligament of the shoulder resulting in tightness due to contraction
Adhesive capsulitis - epidemiology
Middle age
Commoner in females
Adhesive capsulitis - cause
Can occur after shoulder surgery
Diabetes
High cholesterol
Adhesive capsulitis - clinical features
FREEZING
- progressive severe pain, constant pain, pain at night
FROZEN
- pain eventually subsides as stiffness increases
- limitation of movement
THAWING
- stiffness gradually disappears over time and shoulder recovers
- patient gets movement of their arm back
Adhesive capsulitis - examination
Restriction of range of movement (unable to externally rotate arm)
Adhesive capsulitis - investigations
X-ray
- should be normal
Adhesive capsulitis - management
Non operative - physio, analgesia - intra-articular glenohumeral injections Operative - arthroscopic capsular release
Rotator cuff tear - definition
Tears can be partial or full thickness
Lack of muscular stability
Rotator cuff tear - causes
Tendon degeneration
Sudden jerk
