Hip calcification and robotic surgery

The hip is one of the most weight-bearing joints in our body. The hip joint is formed by the spherical head of the femur-thigh bone and the hollow part of the pelvis-pelvis bone called the socket-acetabulum. Both the head of the femur and the surface of the socket are covered with cartilage tissue, which allows the joint to move easily. This causes calcification, which is a degenerative joint disorder characterized by the deterioration, wear and tear of the cartilage tissue for various reasons.

Causes of hip joint calcification

Primary joint calcification, also known as “wear and tear”, in which cartilage deteriorates over time with advancing age

Articular calcification resulting from hip joint dysplasia, also known as developmental deformity-deformation of the hip or hip dislocation.

Secondary articular calcification as a result of fractures affecting the hip joint or severe trauma that causes dislocation of the hip

Joint calcification caused by involvement and deterioration of the hip joint in inflammatory rheumatic diseases such as rheumatoid arthritis or gout

Articular calcification, which occurs as a result of avascular necrosis, which causes the bone to deteriorate, collapse in the head and lose its spherical structure, as a result of the inability to carry healthy blood to the head of the thigh bone in the hip joint due to various reasons.

Patients in the first period of osteoarthritis experience mild pain, stiffness, partial strain on some hip movements, inability to run, and inability to do sports. In this early period, if the patient is overweight, it is recommended to weaken and reduce the load on the joint, thus slowing down the wear. In the early period, relief is provided by physical therapy and exercise program, drugs, various injections into the joint. It is important to maintain the strength and flexibility of the muscles around the joint by exercising regularly.
However, as the calcification progresses over time, the limitation of movement, which becomes evident as a result of the deterioration and deformation of the joint structure, causes difficulties even in the daily basic simple movements of the person (such as walking, standing, squatting). As a result, calcification results in the inability of the joint to perform its function in the body, that is, when it is considered as an organ, “joint failure”.

In this case, the surgical treatment to be applied; It is a hip joint prosthesis surgery that will enable the person to perform daily movements painlessly and comfortably.

Robotic hip joint replacement surgery

Hip joint replacement surgery is a surgical procedure in which the hip joint is replaced with artificial implants (prosthetic parts).

Correct placement and alignment of implant parts is the most critical factor in hip replacement surgeries. MAKO hip robotic surgery provides a superior level of accuracy and precision in the placement of prosthetic implants. This technology uses patient-specific anatomical information obtained by preoperative CT scan to adjust the correct position of the implants, reducing the rate of bone collision and implant displacement.

Before robotic hip joint replacement surgery, 3D computerized tomography of the hip is taken. On the basis of the information obtained from tomography, a surgical plan suitable for each patient’s anatomy is prepared. Information is collected by matching the patient’s real bone anatomy with tomography images via a high-resolution camera and transferred to this robotic system. It combines the physical anatomy of the patient with the virtual bone anatomy visible on the CT scan. Afterwards, the robot provides physical, auditory and visual guidance to the surgeon in placing the prosthetic parts at right angles specific to the patient.

The robotic total hip replacement method, performed under the control of the surgeon, minimizes the margin of error and ensures that the postoperative recovery period is shorter, more painless and more comfortable.
