Investigation
Film X-Ray
Left anterior shoulder
dislocation with Greater
tuberosity fracture

• On Lt. arm sling

dislocation
Radiological evaluation
Posterior shoulder
dislocation
• Most common shoulder injuries
• Mechanism : anteriorly directed force on
the arm when the shoulder is abducted
and externally rotated
• Associated injury
–Axillary nerve
–Hill Sachs defect
–Bony Bankart lesion
–Greater tuberosity fracture

Anterior shoulder dislocation
Clinical presentation & Physical
examination
• Pain [severe]
• Hold limb with normal limb by side
of body.
• Abduction and external rotation.
• Pt can’t touch apposite shoulder
[Dugar test]
Clinical presentation
Physical examination
• Load and shift test
– Grade I - increased translation, no subluxation
– Grade II - subluxation of humeral head to, but
over, glenoid rim
– Grade III - dislocation of humeral head over
glenoid rim
• Apprehension sign
• Relocation sign
• Reduction
• simple traction-countertraction is
most commonly used.
• relaxation of patient with sedation
and analgesics.
• Immobilization for 3-4 weeks after
shoulder dislocation does NOT change
the prognosis compared with
immediate mobilization
Management
Reduction Maneuvers
• Most Common Techniques
–Kocher (71-100%)
–External Rotation (78-90%)
–Milch (70-89%)
–Stimson (91-96%)
–Traction/Countertraction
–Scapular Manipulation (79-96%)
Reduction Maneuvers
Reduction Maneuvers
• More missed diagnosis .
• Mechanism : flexed, adducted, and
internally rotated arm is a high-risk
position.
Posterior shoulder dislocation
Clinical presentation
• Internal rotation
• Flat front of shoulder
• Prominent coracoid
• Prominent post aspect of shoulder
Management
• Under GA reduction by pulling arm in
adduction to disengage head then
lateraly rotate while pushing head
anteriorly.
• Immobilization in external rotation and
abduction for 3 wks.
