F – Frozen shoulder exacerbating medications

D – Drugs causing systemic stiffness

R – Relaxants (inappropriate use)

U – Unprescribed painkillers

G – Glucocorticoids (excessive use)

S – Sedatives (limit mobility)


Radiological Features of Frozen Shoulder:


C – Capsular thickening

A – Acromiohumeral distance reduced

P – Periarticular osteopenia

S – Soft tissue shadowing

U – Uniform joint space

L – Loss of subacromial space

E – Erosions absent

X – X-ray often normal in early stages

R – Reduced translucency

A – Arthrography shows reduced volume

Y – Y-shaped capsule on MRI


Diagnostic Tests for Frozen Shoulder:


T – Thermal imaging (for inflammation)

E – Electromyography (for muscle activity)

S – Strength testing

T – Tendon reflex examination

S – Sonography (ultrasound)

H – Hydrodilation (distension arthrography)

O – O’Brien’s test (labral tear)

U – Ultrasound (for soft tissue)

L – Lateral rotation test

D – Dupuytren’s contracture examination

E – Elevation test

R – Range of motion assessment


Laboratory Findings In Frozen Shoulder:


B – Blood glucose (for diabetics)

L – Lipid profile (to rule out other conditions)

O – Osteoarthritis markers (for differential diagnosis)

O – Organ function tests (kidney, liver)

D – D-dimer (to rule out thrombotic conditions)

F – Full blood count (to check for infection)

R – Rheumatoid factor (for autoimmune diseases)

E – Erythrocyte sedimentation rate (ESR for inflammation)

E – Electrolytes (for overall health)

Z – Zinc level (overall nutritional status)

E – Enzyme markers


Complications of Frozen Shoulder:


S – Synovial fluid reduction

T – Tendon tears (secondary)

U – Unresolved pain

C – Capsule fibrosis

K – Knots in muscles (trigger points)

J – Joint degeneration

O – Osteopenia (local)

I – Inflexibility lasting years

N – trauma can also cause spondylolisthesis.
