Pathology - Shoulder Girdle Flashcards
Hill-Sachs Defect
A compression fracture or defect involving the artciular surface of the humeral head.
Often associated with shoulder trauma and/or anterior dislocations of the shoulder
Impacted Fracture
A bony fragment is wedged into another fragment.
Common in shoulder and hip fractures
Articular Fracture
Involving the joint surface
Pathologic Fracture
Fracture due to bone destruction caused by disease.
Cancer is the primary cause. The fracture may not be caused by trauma, but by routine activities
Fracture Dislocation
A fracture accompanied by a bone out of a joint
AC Dislocation
Distal clavicle is usually displaced superiorly causing widening of the AC joint space
Rotator Cuff Tear
Traumatic injury to one or more of the muscles that make up the rotator cuff
Tendonitis
Inflammatory condition of the tendon
Bursitis
Inflammation of the bursa or fluid-filled sacs enclosing the joints
Dislocation/Luxation
Dislocation of a bone from a joint
Subluxation
Partial dislocation
