An example of a joint effectively treated using arthroscopy is the hip. Though, in the case of severe impact damage or advanced osteoarthritic degeneration, arthroscopy is used more as a diagnostic tool. Here, the emphasis of arthroscopy is to fine-tune the medical understanding of a condition after completing X-Rays. The more detailed aspects of a hip condition can be gauged by arthroscopic observation and the need for a replacement, enacted on according.
Hip replacement is a surgical intervention appropriate for irreversible conditions. The nature of how a hip replacement is done can vary considerably in the amount of the joint and bone that is removed and then replaced. The two most common variations of hip replacement are the half, (or hemi), hip replacement and the total hip replacement.
The joint bones of the hip are the acetabulum and the femoral head. With a total hip replacement both are removed and replaced with a prosthetic implant: a ball and socket configuration. The medical term for this procedure is arthroplasty. With the half hip replacement, (or hemiarthroplasty), the femoral head is the most common side of the joint to be replaced.
The acetabulum is a concaved formation of bone on the lower, side faces of the hip bone. In anatomical terms, the acetabulum sits almost at the lateral conjunction between the ilium, (which is the upper open planed section of the hip), and the ischium, (comprising the lower and side boundaries of the hip).
The surface area of the opening of the acetabulum would be smaller than the palm of a person’s hand. Within the opening, it forms a neat socket with a narrow extension, or finger of bone, that curls to hug the ball of the femoral head. This bone creates the back and lower lip of the opening.
For the half hip replacement, the femoral head is predominantly the side of the joint replaced first. The femoral head is the highest end of the thighbone, (the femur), and has a distinctive head and neck shape to fit neatly into the joint socket of the acetabulum.
What makes up a hip?:
Both the ilium and the ischium constitute about 40% of the total mass of the hip bone. The pubis region of the hip bone is located at the midline of the hip and makes up the last 20% of the hip bone as a whole.
