Künstliche Hüfte - minimal-invasive OP (Kurzversion) von Prof. Christian Hendrich

Summary

This video script provides an informative overview of hip replacement surgery, focusing on the benefits of artificial hip joints for patients suffering from osteoarthritis. It explains how modern prosthetic joints alleviate pain and restore mobility, highlighting the importance of preserving muscle tissue during surgery. The procedure is described in detail, including the use of minimal invasive techniques, ceramic components, and precise surgical instruments. The video emphasizes the life-changing impact of this surgery, offering patients the potential for improved quality of life, even allowing for continued physical activities like sports.

Takeaways

• 😀 The artificial hip joint is one of the best available surgical options, with 97% of patients willing to undergo the procedure again due to significant pain relief.
• 😀 Hip osteoarthritis causes cartilage damage, inflammation, pain, and restricted movement, which is evident through limping.
• 😀 Modern artificial hips replace the damaged cartilage and can support complex, three-dimensional movements, such as in activities like golf.
• 😀 These artificial joints are durable and suitable for continuous, high-impact activities like jogging.
• 😀 The minimally invasive procedure for hip replacement involves small skin incisions and preserves muscle tissue beneath the skin.
• 😀 Ceramic hip implants are designed for low wear and long-lasting use, allowing patients to engage in sports and other physical activities.
• 😀 During the surgery, the patient is placed on a specialized table, and the leg is positioned for optimal access to the hip joint.
• 😀 The operation involves using a precision saw to remove the femoral head and cartilage, with a special tool to install the new hip joint components.
• 😀 The new joint includes a ceramic liner and is inserted into the pelvis with minimal disruption to surrounding tissues.
• 😀 The final step of the procedure involves securing the femoral stem with a custom-fitting design that locks firmly into place, ensuring stability of the new joint.
• 😀 The surgery is concluded by closing the muscle layers naturally, with only the skin and fascia requiring suturing. The procedure’s success hinges on the level of pain and quality of life impacted by hip discomfort.

Q & A

What is the main benefit of an artificial hip joint surgery?

The main benefit of an artificial hip joint surgery is the significant pain relief it provides. 97% of patients who undergo the surgery report being willing to undergo it again due to the long-term relief from the pain associated with hip osteoarthritis.

What causes pain in hip osteoarthritis?

Pain in hip osteoarthritis is caused by damage to the cartilage, leading to inflammation and restricted movement. This damage is often visible through a limp in the affected patient.

How do modern artificial hip joints work?

Modern artificial hip joints replace the damaged cartilage and can perform complex, three-dimensional movements, such as those required in sports like golf. They are designed for durability and can handle long-term stress, making them suitable for activities like jogging.

What makes the ceramic hip joint implant special?

The ceramic hip joint implant is notable for its low wear characteristics, making it suitable for long-term use. It is also 'dislocation-safe' due to its large head diameter and smooth, ceramic bearing surfaces.

What is minimal invasive surgery in the context of hip replacement?

Minimal invasive surgery involves smaller skin incisions (typically under 12 cm) and focuses on preserving the surrounding muscles. The muscles are gently separated rather than cut, reducing recovery time and postoperative pain.

How is the surgery performed without damaging muscles?

During the surgery, specialized instruments are used to gently move the muscles aside without cutting them. The hip joint is accessed via a precise surgical approach that avoids damaging the surrounding tissue.

What tools are used in the procedure?

The procedure uses a precision oscillating saw to cut the femoral neck, and special instruments like the 'raffelfräse' are used to remove cartilage. Additionally, a 'Pressfit' cup with a ceramic bearing is pressed into the pelvis to replace the damaged joint.

How is the femoral head replaced in the surgery?

The femoral head is replaced by a ceramic ball, which is securely pressed onto the prepared femoral stem. This ceramic component ensures smooth motion and low wear.

What makes the new hip joint resistant to dislocation?

The large diameter of the ceramic femoral head, combined with the specific surgical positioning of the joint, ensures that the new hip joint is 'dislocation-safe' and can remain stable in all positions.

What is the role of the muscles in the success of the surgery?

Preserving the muscles during the surgery is crucial because it ensures faster recovery and minimizes postoperative complications. The muscle integrity aids in maintaining joint stability and helps the body heal quickly after the procedure.
