Artificial hip replacement surgery



Hallym University Dongtan Sacred Heart Hospital (Hospital Director Han Sung-woo) is helping patients recover quickly by performing artificial hip arthroplasty to prevent dislocation after hip fracture surgery and preserve hip extraversion.

The hip joint is the joint that connects the acetabulum and the femur. It is involved in many movements of our body, such as walking, sitting, and standing up. However, fractures of the hip joint due to trauma such as falls or traffic accidents can lead to fatal complications. In particular, the elderly, whose bones are weakened due to osteoporosis, can fracture their hip joints even with a small impact.

When hip fractures occur, it is impossible to walk and move for a long time due to severe pain. As a result, immunity is reduced, blood circulation is not smooth, and the risk of developing bedsores, pneumonia, blood clots, and strokes is increased. In the case of the elderly with underlying diseases, cardiopulmonary function is weakened and heart disease and high blood pressure can occur. According to the American Journal of the Bone Joint Association, the mortality rate within a year reaches 36.4%. If you do not undergo surgery after a hip fracture, the mortality rate due to general complications has increased to 84.4%.




For this reason, if the hip joint is fractured, surgical treatment is absolutely necessary. In particular, if a fracture occurs in the femoral neck close to the femoral head, it is difficult to heal naturally, so artificial hip arthroplasty is performed to remove the damaged bone head and change it into an artificial bone head. This is a preferred surgical method for elderly patients because it is simpler and faster to recover than hip arthroplasty, which replaces all pelvic joint cartilage.

Despite these advantages, patients suffer from postoperative recovery because the artificial hip replacement also has a large incision site and incisions major muscles in the hip joint. In particular, hip dislocation occurs up to 10% due to postoperative complications. To prevent these complications, Professor Ko Young-seung of orthopedic surgery at Hallym University's Dongtan Sacred Heart Hospital is performing artificial hip arthroplasty that preserves the external rotator.

In the existing artificial hip arthroplasty, the upper part of the joint sac surrounding the femoral head was incised. As a result, the weight-supporting joint tissue was damaged, and hip dislocation in the upward direction frequently occurred after surgery. In response, Professor Ko preserved the upper joint sac, where dislocation occurred, and allowed the surrounding tissues to recover quickly with a surgical method of incising the lower part of the joint sac. With these surgical methods, no hip dislocation has occurred since artificial hip replacement surgery.




In this regard, Professor Ko Young-seung published a study last year in the SCIE-level international journal on the effectiveness of artificial hip arthroplasty for Bipolar Hemiarthroplasty: Comparison with Superior Capsulotomy' to prevent dislocation after hip surgery.

Recently, in order to secure the surgical site during artificial hip arthroplasty, an external rotator conservation approach is being implemented to preserve the incisional external rotator of the hip. The hip extracorporeal muscles play a role in stabilizing the hip and strengthening the power of movement. Professor Ko Young-seung has shortened the operation time and enables patients to walk faster and independently after surgery with a surgical method that preserves these extracorporeal muscles.

Professor Ko Young-seung said, "The existing artificial hip surgery has been very worried about the long recovery period and hip dislocation, but the new artificial hip arthroplasty can minimize the occurrence of complications and recovery period, so it is highly satisfactory." "If the hip area appears to be swollen or bruised due to a fall accident, and hip pain is felt, rapid treatment is needed. In addition, he explained, "If you continue to do light exercise that is not unreasonable considering your health condition, you can prevent hip fractures."
