Shoulder Flashcards
Two bursae associated with the shoulder
Subacromial bursa
Subascapular bursa
Name for the shoulder joint
Glenohumeral joint
Ligament round the shoulder joint
Capsular ligament
What forms the rotator cuff?
The tendons of the SITS muscles
Night pain and shoulder impingement?
Night pain not common
When will shoulder impingement hurt?
Pain on movement
Painful arc
Hawkins test
PAINFUL CRECENDO NOT ASSOCIATED WITH SHOULDER IMPINGEMENT
Differential diagnosis for shoulder impingement?
Shoulder impingement
Frozen shoulder
Shoulder instability
Bigliani acromial grading
flat inferiorly
curved
parallel to the humeral head with concave undersurface
considered most common type 3
hooked
most anterior portion of the acromion has a hooked shape
associated with increased incidence of shoulder impingement
convex (upturned)
most recent classification of acromion process shape
the undersurface of the acromion is convex near the distal end 4
no convincing correlation between a type 4 acromion and impingement syndrome exists 4, 5
OS acromiale
Unfused acceossory ossification centre
Rotator cuff tear signs & symptoms
Night pain
Weakness
Muscle wasting
Surgical ways of fixing shoulder problems
Cuff repair (feeding tendon through hole drilled in bone)
Suture anchor
Shoulder arthroplasty
Injection you could give into the shoulder
-From GPPC lecture
Steroid
Medrone with lignocaine (medrone is a steroid)
Which shoulder problem is more common in diabetics?
Frozen shoulder
Which bones form the shoulder girldle?
The scapula, the acromopn and the humerus and the supporting muscles including the deltoid and the muscles of the rotator cuff
Where do the supraspinatous, infraspinatous and teres minor attach to?
The greater tuberosity
Supraspinatous is responsible for initiating abduction
Infraspinatous and teres minor are external rotators
What does the subscapularis do?
Internal rotation
Subscapularis attaches to the lesser tuberosity
Shoulder condition with painful arc?
Shoulder impingement
Which tendons of the rotator cuff are usually compressed in shoulder impingement?
Supraspinatous
Where does pain of shoulder impingement typically radiate to?
The upper arm and deltoid
Pain may be felt under the lateral edge of the acromion
Which test can be used to re-create the pain of shoulder impingment?
Hawkins-kennedy test
Treatment for shoulder impingement
Treatment is conservative in the first instance with the majority of cases settling with NSAIDs, analgesics, physiotherapy and subacromial injection of steroid. Up to 3 subacromial injections may be required. Cases which do not improve with these interventions may benefit from subacromial decompression surgery to create more space for the tendon to pass through. This procedure can be done as an open procedure (through an incision large enough to visualise the subacromial space) or with minimally invasive arthroscopic techniques (when small instruments and a keyhole camera are inserted into the subacromial space to perform the surgery) .
The tendons of which muscle are usually involved in a rotator cuff tear?
Supraspinatous
Large tears can extend into the infrapinatous and subscapularis
How do you confirm a rotator cuff tear?
Ultrasound or MRI
What does supraspinatous do?
Initiation of abduction
