What is it indicated for?

noninflammatory degenerative joint disease including osteoarthritis and

avascular necrosis; rheumatoid arthritis; correction of functional deformity;

ravieion procedures where other treatments where devices have failed; and

treatment of nonunion, femoral neck and trochanteric fractures of the

proximal femur with head involvement, which is unmanageable using other
