ORTHOPEDICSTREATMENT
Traction and reduction of humeral head anteriorly
COMPLICATIONS
Often associated with humerus fractures
INFERIORSHOULDERDISLOCATION(LUXATIOERECTA)
■ Therarestof shoulder dislocations (<2%)
■ Always indicative of serious injury
■ Results from hyperabductionof the shoulder
DIAGNOSIS
Arm is held in a fixed position up over head (180° of elevation). X-ray is con-
firmative (see Figure 4.12).
TREATMENT
Reduction by traction-countertraction
COMPLICATIONS
■ Almost always accompanied by disruption of the rotator cuff and tear
through the inferior capsule
■ High incidence of neurovascular compromise, including axillary nerve,
brachial plexus, and axillary artery injuries
■ Fractures of the proximal humerus
