ACROMIAL-CLAVICULAR
JOINT SEPARATION
Separation of the acromial-clavicular joint results from falls
on the tip of the shoulder. Cases are classified by the amount
of upward displacement of the clavicle (Figure
18.4).
Evaluation
The
acromial-clavicular joint is tender to palpation and
the end of the clavicle is prominent. X-rays are not
essential but confirm the diagnosis and determine if
there is a fracture.
Treatment
| :: |
Apply
an arm sling to support the weight of the arm and
to remove the deforming force from the joint. This
will not keep the joint in the anatomical position,
but the remaining deformity will cause little functional
loss. |
| :: |
Release
the sling daily to allow elbow extension. Begin
hanging arm exercises when comfortable and begin
active muscle strengthening by the second week. |
