MSK Flashcards
Characteristics/quality of pain: Nerve Bone Vascular Muscle
Nerve: sharp, burning, follows a nerve
Bone: deep, localized
Vascular: diffuse, aching, poorly localized, many be referreed
Muscle: dull and aching, poorly localized, may be referred
Referred sites of pain: Neck Back Appendix Heart/diaphragm
Neck: arm
Back: leg
Appendix: (hip) right iliac fossa
Heart/diaphragm: shoulder
Inflammatory versus degenerative pain characteristics
Inflammatory: morning stiffness > 30 min, pain w/ erythema, warmth, swelling, responds to NSAIDS
Degenerative: pain worse at end of day, after activity, morning stiffness < 30 min if present
Neurologic symptoms
cauda equina symptoms, bowel/bladder incontinence or retention, headaches, weakness
Claudication: vascular symptoms
Exercise-induced, no pain at rest, pain stops within 10 min of stopping activity. Calf, buttocks, thigh, foot pain. Must differentiated from neurogenic symptoms (spinal stenosis, sciatica)
SEADS
Swelling Erythema Atrohpy Deformity Skin changes
WETCJ
Warmth Effusion Tenderness Crepitus Joint stability
Causes of hypermobile joints
Ligament
Collegen disorders
Tendinitis
RA
Causes of hypomobile joints
muscle strains
pinched nerves
tendinitis
OA
What is end-feel? What are the different types?
End-feel is felt by the examiners hand at the end of passive ROM.
Bone - bone: cold stop, elbow extension
Soft tissue approximation: muscles coming together like pillows squishing, elbow flexion
Tissue stretch: springy/firm with slight give, tendons stretching, wrist flexion
ADLS (DEATH)
dressing eating ambulating toileting hygiene
Trendelenburg sign
contralateral hip drop (lift good leg)
Trendelenburg gait
waddle
Circumduction gait
leg swings around
Limp
Antalgic
Impingement syndrome (shoulder) characteristics
night pain
dull ache
weakness with arm drop test
atrophy of rotator muscles
Rotator cuff injury
Weakness with arm drop
Atrophy of rotator cuff muscles
Night pain
Subacromial bursitis
Tenderness at anterior-inferior acromion
Limited ACTIVE ROM but full PASSIVE ROM
Bicipital tendon rupture (Proximal)
Asymmetry with bulge deformity
Sharp ache
Hx trauma
Bicipital tendonitis
Overuse injury
Dull ache
Tenderness over biceps groove
Labral tear
Hx trauma (dislocation) or overuse (throwing injury).
Mimics rotator cuff!!
Instability.
Suspect based on demographic, hx, lack of response to conservative treatment.
AC pathology
Painful Arc
Painful and tender over AC
Adhesive capsulitis
Frozen shoulder.
Early phase pain may be the only symptom.
Pain at night or with movements to constant pain.
Later phase global restriction in active or passive ROM
Consider fasting glucose - prevalent in DM.
Axillary nerve mononeuropathy
shoulder flexion/abduction/external rotation (FEAR) weakness. Atrophy deltoid teres minor.
Suprascapular nerve palsy
overhead abduction, external rotation weakness (OAR)
Long thoracic nerve injury
Shoulder flexion and overhead. Scapular winging and atrophy of serrates anterior.
Rotator cuff tear
unable to raise arm overhead, positive arm drop test/empty can test
Cervical nerve root lesion
myotome weakness. Pain and sensation reduction in dermatome distribution, Reduced DTR.
Spinal accessory nerve pathology
Traps, SCM, scapular winging. Reduced flexion and abduction.
SITS
supraspinatus
infraspinatus
teres minor
subscapularis
Shoulder ROM
Forward flexion 180 Backward flexion 60 Abduction 180 Adduction 50 ER 90 IR 70
Shoulder assessment:
Inspection and Palpation
Inspection: contours, clavicles, SC/AC joints, scapulae, SEADS
Palpation: SC/AC/GH joints. Biceps groove, subdeltoid bursa, AC joint and rotator cuff insertion. Check GH for crepitus by palpation of subacromial bursa and passive circumduction
Special tests for: General shoulder instability
o Anterior apprehension: push forwards (anteriorly) on humeral head while externally rotating shoulder passively. Popping or fear of pain/dislocation = positive.
o Relocation test: posterior pressure on humeral head = resolved apprehension (positive)
o Anterior release test: positive if when releasing hand (from postrior pressure above) = pain/apprehension
o Load and shift: compress into glenoid (stabilize) and stabilize scapula then move humeral head anterior/posterior… shift should be < 25% ant and < 50% posterior
o Sulcus: pull arm vertically down (anatomic position), if humeral head slides inferiorly or gap = positive
Special tests for: Glenoid labral pathology
o O’Brien’s: adduct and internally rotate arm, then apply downward pressure against resistance… then repeat w/ externally rotate. Postive = pain with supination, relief with pronation.
o Anterior slide: hands on hips, stabilize clavicle and scapula, push up and forwards on elbow
Special tests for: Rotator cuff tears:
o Drop arm test
o Empty can test: arms 45 degrees, thumbs down, push up against force
o External rotation resistance
o Internal rotation lag: arms behind back, 90 degrees, examiner lifts hand off back. Positive test = patient cannot hold.
o Gerber lift-off test – same set up as internal rotation but patient lifts their hand off back against resistance, pain or cannot lift.
Special tests for: Impingement syndrome:
o Neer’s test: stabalize scapula. Internally rotate and forward flex arm. Anterolateral shoulder pain = positive test.
o Hawkins-Kennedy test – with shoulder and elbow flexed at 90 degrees, passively internally rotate shoulder. Pain = supraspinatus impingement.
o Painful arc test: posive test pain at 60-120 degrees abduction
Special tests for: AC joint pathology
o Scarf test (across body adduction test): adduct on horizontal plane. Positive test: pain in AC
