Shoulder Flashcards
Internal rotation of arm
Posterior shoulder dislocation
Serratus anterior pathology
Ask patient to push against wall
Scapular winging
jobes test is testing for
Supraspinatus
Jobe’s test
Patient internally rotates arm whilst in 45 degree abduction and 30 degree forward flexion with an extended elbow
Attempts to further abduct against resistance on the elbow results in pain
Belly-press test and Gerber’s test
Test for subscapularis
Belly press test
Patient presses on their abdomen
Positive if elbow drops posteriorly as there is pain on internal rotation of the shoulder
Gerber’s test
Patient holds hand behind their back with palm facing outwards
Push on patient’s hand while they resist movement
Positive if unable to lift hand away from back
Infrasponatus and Teres minor
Flex elbow to 90 degrees and externally rotate against resistance
Rotator cuff tear
Drop arm sign
Rotator cuff tear movement
Patient lowers arm slowly from 160 degree abduction
Positive if patient can’t control the arm, and it drops quickly to the side
Treatment of rotator cuff tear
Analgesia and physio
Tears may need surgical repair
Winging
Long thoracic nerve
Pain on 0-20 of abduction
Full thickness tear (rupture) of the supraspinatus tendon 0-20
Pain on 20-40 abduction
Auxiliary nerve damage
Deltoid not working
Pain on abduction 40-60
Adhesive capsulitis
Frozen shoulder
Pain on 60-120 abduction arc
Subacromial painful arc
Pain on 120-180 abduction
Acromioclavicular painful arc
Painful arc test
60-120 abduction
Painful arc test results
Pain exacerbated by thumb pointing down (empty can sign)
Pain better with thumb pointing up (full can)
Painful arc between 160-180
Acromioclavicular joint pathology e.g. OA
neer’s test
Passive flexion of the shoulder with a pronated arm, whilst scapula is stabilised
hawkin’s test
Shoulder and elbow both flexed to 90 degrees
Pain on passive internal rotation as the rotator cuff rubs on the undersurface of the acromion- external rotation may relieve pain
Treatment of subacromial impingement syndrome
Analgesia
Physio
Steroid injection
Surgery (arthroscopic acromioplasty) if this fails
Biceps tendinopathy
Speeds test
Speeds test
Ask patient to place arm out in front of them with elbow flexed at 30 degrees and palm facing up
Push down on patients palm while they resist movement
Positive if pain felt at bicipital groove
treatment of biceps tendinopathy
Analgesia (+/- steroid injection but risks tendon repture)
Acromioclavicular joint pathology
Scarf test
Scarf test
Ask patient to place hand over opposite shoulder as if putting on a scarf
Push lightly at the elbow to force abduction
Positive if pain at ACJ
Shoulder stability
Crank shoulder apprehension test
Patient holds their hand out like they’re giving a high-five
Then pull back elbow and push proximal humerus forward
Function for shoulder
Combing their hair
Put on jacket
Adhesive capsulitis (frozen shoulder) symptoms
Reduced active + passive ROM in all directions +/- pain in painful phase
Treatment of adhesive capsulitis
Analgesia and physio (if tolerated)
Surgery (manipulation under GA or open/arthroscopic release of adhesions)
OA of shoulder history
Often secondary to chronic shoulder instability or chronic rotator cuff tear
Treatment of OA
Analgesia and physio +/- steroid injection +/- surgery
proximal biceps rupture
Rupture of long head tendon
Proximal biceps rupture history
Discomfort after something has ‘gone’ when lifting or pulling
Proximal biceps rupture example
‘Ball’ appears in the muscle on elbow flexion like a ‘popeye’ muscle
Proximal biceps rupture treatment
repair rarely indicated as function remains
However if tendon insertion is ruptured surgical repair will be needed
Distal biceps rupture
Rupture of biceps muscle
Distal biceps rupture history
Men involved in heavy lifting
Sometimes ‘tearing’ or ‘popping’ and pain in antecubital fossa with bruising over medial forearm
Distal biceps rupture treatment
Needs urgent surgical repair
Poly myalgia rheumatica
Pain in shoulders but no weakness, examination of shoulders normal
May be associated with mild polyarthritis, tenosynovitis and carpal tunnel syndrome
Poly myalgia rheumatica treatment
Prednisolone 15mg/d PO
Anterior (glenohumeral) shoulder dislocation history
Usually contact sports with arm forced into abduction, extension, and external rotation
Anterior shoulder dislocation exam
Loss of shoulder contour
Anterior bulge from head of humerous
Anterior shoulder dislocation investigations
XR
Anterior shoulder dislocation treatment
Simple reduction
Acromioclavicular dislocation history
Typically direct blow on top of shoulder in young contact-sport athletes or a fall on outstretched hand
Acromioclavicular dislocation exam findings
Tender prominence over ACJ
Pain on abduction of arm across body
Acromioclavicular investigations
XR
Acromioclavicular dislocation treatment
Broad arm sling if minimal displacement
Open reduction and ligament reconstruction for more severe disruption
Clavicle fracture history
Direct blow on top of shoulder (common in cyclists) or a fall on outstretched hand
Clavicle fracture treatment
Broad arm sling with follow-up on XR at 6 weeks
Inflammatory arthritis history
Pain and stiffness in the morning alleviated by movement
Systemic features
Inflammatory arthritis investigations
Bloods for inflammatory and autoimmune markers +/- XR
Crystal arthropathy history
Acute, extremely painful
Gout presentation
Elderly Male or post-menopausal female HTN CKD Diuretics (spironolactione, furosemide, thiazides) Diet (alcohol, red meat) Myelo/lymphoproliferative disorders
CPPD presentation
Elderly Haemochromatosis Wilson’s disease Acromegaly Hyper parathyroid is Hypophosphataemia Hypomagnesaemia
Gout exam
Monoarthritis
>50% in 1st MTP
Also ankle, foot, hand, wrist, elbow, knee (rare in shoulder)
May be tophi found
CPPD exam
Acute monoarthritis
RA-like polyarthritis
or chronic OA with CPPD flares
Knee, wrist and shoulder most commonly affected
Crystal arthropathy investigations - bloods
Serum urate
Crystal arthropathy investigations - Joint aspirate
To exclude septic arthritis
In gout- negatively birefringent needle-shaped urate crystals
In CPPD- weakly positively birefringent rhomboid-shaped crystals
Crystal arthropathy investigations - XR
Gout- soft tissue swelling, then later ‘punched-out’ erosions
CPPD- soft tissue calcium deposition and chondrocalcinosis
Management of gout
High-dose NSAID/colchicine and rest for acute attack
Allopurinol for prevention
Management of CPPD
Rest and cool packs for acute attack
NSAIDs + colchicine for prevention
Septic arthritis history and exam
Extremely painful, hot, swollen joint of acute onset
Systemic upset
Septic arthritis investigation
Joint aspirate to decompress the joint and send off for Gram stain, MC+s, cytology and polarised light microscopy
Septic arthritis treatment
6-12 weeks antibiotics depending on sensitivities
Start flucloxacillin empirically if in doubt
