Glenohumeral dislocation vs acromioclavicular separation
GH dislocation:
anterior + inferior displacement of the humeral head from the glenoid fossa of the scapula (see chart)
(traumatic event such as a fall onto an outstretched arm, a direct blow to the shoulder, or forceful twisting of the arm)
AC seperation:
the disruption of the ligaments connecting the acromion of the scapula to the clavicle
(due to a direct impact to the top of the shoulder, such as a fall onto the shoulder or a collision during sports)
Glenohumeral dislocation causes what type of injuries
- Labrum
- Hill-Sachs Lesion
Mechanism of injury for an ACL tear
Hyperextension
Cranial nerve roots/myotomes (cervical + lumbar regions)
C2: cervical flexion and extension
C3: lateral flexion
C4: glenohumeral elevation and depression
C5: glenohumeral abduction
C6: beggar (humeroulnar flexion and radiocarpal extension)
C7: kissing the rings (humeroulnar extension and radiocarpal flexion)
C8: thumb extension and finger flexion
T1: finger abduction
L2: quadricep & tibiofemoral flexion
L3: quadricep & tibiofemoral extension
L4: talocrural dorsiflexion
L5: hallux extension
