Care must be taken with this procedure, as there is some chance of interfering with the blood flow to the femur. Ad. There are also different types of hip arthroplasty surgery in common use today. Hemi-arthroplasty is a procedure that is employed when the femoral head is so damaged that it is deemed beyond repair. The damaged head is removed, and a prosthetic is implanted.
