What are the main causes of ACJP?
- direct trauma to adduced shoulder
How would you investigated
Tenderness on scarf test
What is the scarf test?
passively flex are so it’s parallel with the ground and passively adduct - should be painful
What is the treatment of an AC ligament sprain?
Rest, ice, sling
ROM for strengthening exercises
What are the clinical feature of AC ligament sprain?(T1)
- Mild tenderness
- No deformity
- pain on active ROM
What are the clinical features of a torn AC ligament?
- Significant AC joint swelling
- Minimal tenderness over CC joint
What are the X-ray features of a torn AC ligament? (T2)
Partial elevation of the distal clavicle with minimal widening of the CC (cricoclavicular)

- lateral view may be needed to see posterior dislocation
What are the clinical findings of a complete AC dislocation? (T4)
- displacement of distal clavicle through trapezius
What are the clinical features of T5?
- Superior dislocation which is 1 to 3 times more than normal spacing

- shoulder appears dooped
- Clavicle perched above muscle and does not reduce when shruged
What are the X-ray features of T5?
Clavicle is elevated above acromion approximately 1-3x width of the clavicle
CC distance is increased 2-3x normal range
What are the clinical features of T6?
