What are hip replacements?

Hip prostheses are medical implants used to treat hip joint diseases such as osteoarthritis or injuries. They are made of various materials such as metal, plastic, or ceramic and serve to replace damaged or diseased parts of the hip joint.

The function of hip prostheses

The hip joint is one of the largest and most mobile joints in the human body. It enables movements such as walking, running, jumping, and bending. However, if the hip joint is damaged by diseases such as osteoarthritis or injuries, severe pain and restricted mobility can occur. In such cases, a hip replacement can relieve pain and restore the patient's mobility.

Types of hip replacements

There are various types of hip replacements that can be used depending on the individual case and the patient's needs. The most common types include:

• Total endoprosthesis (TEP): In this type of prosthesis, both the femoral head and the acetabulum are replaced by artificial implants.
• Partial hip replacement (HHR): In this procedure, only the damaged part of the hip joint is replaced by a prosthesis, while the healthy part is preserved.
• Surface replacement prosthesis: This type of prosthesis only replaces the damaged surface of the femoral head, while the natural hip socket remains intact.
• 
  

Applications of hip prostheses

Hip replacements are frequently used in patients with advanced osteoarthritis, rheumatoid arthritis, hip fractures, or other serious hip joint diseases. They are used when conservative treatment methods such as medication, physiotherapy, or injections no longer provide sufficient relief from symptoms and the patient's quality of life is severely impaired.

The role of the surgeon

Hip replacement surgery requires careful planning and execution by an experienced orthopedic surgeon. The surgeon selects the appropriate type and size of prosthesis based on the individual patient's case and performs the procedure with the utmost precision to achieve optimal results.

Indications for a hip replacement

The decision to implant a hip prosthesis is usually made by an orthopedic surgeon and is based on various factors. These indications can include both clinical and quality-of-life aspects and vary depending on the individual patient's case. The following are some of the most common indications for a hip prosthesis:

Severe hip pain:

Severe and persistent hip pain can be a significant indicator that a hip replacement is necessary. This pain can be caused by various conditions such as osteoarthritis, rheumatoid arthritis, hip fractures, or avascular necrosis, and often significantly impairs the patient's quality of life.

Limited mobility:

Increasingly limited mobility in the hip joint can be another sign that a hip replacement is needed. Patients who have difficulty moving the affected leg, climbing stairs, bending over, or performing everyday activities could benefit from a hip replacement to restore their mobility.

Impaired quality of life:

Hip pain and restricted movement can significantly impact a patient's quality of life, both physically and mentally. Patients whose quality of life suffers due to hip problems could benefit from a hip replacement to alleviate their pain and restore their quality of life.

Worsening despite conservative treatment:

If conservative treatment methods such as medication, physiotherapy or injections no longer provide sufficient relief from hip pain and the patient's symptoms progress, a hip replacement may be considered as a last resort.

Serious hip injuries:

Patients with severe hip injuries, such as hip fractures that cause permanent damage to the hip joint, may also be candidates for a hip replacement. In such cases, prosthesis implantation can help restore normal hip joint function and prevent long-term complications.

Summary:

The indications for hip replacement are numerous and can vary depending on the individual patient's case. Generally, the decision to implant a hip prosthesis is based on a thorough assessment of the symptoms, the patient's quality of life, and the prospects for a successful recovery. It is important that patients with severe hip problems seek medical help promptly and undergo a comprehensive examination to determine the best possible treatment option.

Hip replacement surgery: procedure and execution

Hip replacement surgery, also known as hip endoprosthetics, is a surgical procedure used to treat serious hip joint conditions such as advanced osteoarthritis or hip fractures. This chapter describes the process and procedure of hip replacement surgery in detail

Patient preparation:

Before the procedure begins, the patient is taken to the operating area and sedated under general or regional anesthesia. The exact type of anesthesia is discussed beforehand with the anesthesiologist and the surgeon and determined according to the individual patient's case.

Patient positioning:

The patient is positioned on the operating table in an optimal position for the surgeon. Usually, the patient lies on their back (supine position), with the affected leg carefully supported and aligned to ensure optimal access to the hip joint.

Access to the hip joint:

The surgeon makes an incision above the hip to access the hip joint. The size and placement of the incision can vary depending on the individual case and are discussed with the surgeon beforehand.

Removal of damaged tissue:

Once access to the hip joint has been established, the surgeon removes the damaged parts of the hip joint, including the damaged femoral head and acetabulum.

Prosthesis placement:

After the damaged tissue is removed, the hip prosthesis is placed in the patient's hip joint. The prosthesis consists of an artificial femoral head and a hip socket, which can be anchored in the bone either by press-fit technique or cementation.

Checking the fit and function:

After placing the prosthesis, the surgeon carefully checks the fit and function of the prosthesis to ensure that it is correctly positioned and works smoothly in the hip joint.

Wound closure:

After the procedure is completed, the wound is carefully closed, and drainage tubes are placed if necessary to remove excess blood and tissue fluid.

Aftercare:

After the procedure, the patient is taken to the recovery room for monitoring and recovery. There, their condition is continuously monitored, and pain medication is administered as needed. The patient is then transferred to a ward where they recover from the surgery and are cared for by an interdisciplinary team of nurses, physiotherapists, and doctors.

Summary:

Hip replacement surgery is a complex surgical procedure that requires careful planning, precise execution, and comprehensive aftercare. A structured process and close collaboration between the surgeon, anesthesiologist, and nursing staff ensure that the procedure is performed safely and successfully, providing the patient with improved quality of life and mobility.

To ensure long-term quality of life after hip replacement surgery, regular monitoring and care by an orthopedic surgeon is necessary. This includes regular follow-up examinations, X-rays, and, if necessary, adjustments to medication or physical therapy to detect and treat potential complications early.

Summary:

Long-term quality of life after hip replacement surgery is significantly influenced by improved mobility, reduced pain and discomfort, increased life satisfaction, and positive effects on mental health. Continuous monitoring and care by the orthopedic surgeon allow for the early detection and treatment of potential complications, ensuring the patient's long-term functionality and satisfaction.

Risks and complications of hip replacements

Although hip replacement is an effective treatment option for hip joint problems such as osteoarthritis or hip fractures, the procedure carries certain risks and complications. This chapter explains in detail the most common risks and complications associated with hip replacements:

Infections:

An infection around a hip prosthesis is a serious complication that can occur. Infections can be caused by bacterial contamination during the procedure or by postoperative infections. An infection can lead to pain, swelling, and redness in the hip area and usually requires antibiotic treatment or, in severe cases, even surgical revision of the prosthesis.

Dislocation:

A dislocation, also known as a luxation, occurs when the prosthetic components slip out of their normal position in the hip joint. This can be caused by awkward movements or traumatic events such as falls. A dislocation causes severe pain and usually requires immediate medical treatment to reposition the prosthesis and prevent further damage.

Loosening of the prosthesis:

Hip prosthesis loosening occurs when the prosthesis components become loose within or detach from the bone. This can happen over time due to wear and tear or insufficient bone integration. Prosthesis loosening can lead to pain, instability, and reduced hip joint function and usually requires surgical revision of the prosthesis.

Thromboses and embolisms:

Thrombosis, also known as blood clots, can occur after hip replacement surgery, particularly in patients with an increased risk of developing thrombosis. If a blood clot breaks loose and travels to the lungs, it can cause a life-threatening pulmonary embolism. To prevent thrombosis, patients are usually given blood-thinning medication and encouraged to become mobile soon after surgery.

Nerve injuries:

During the procedure, surrounding nerve structures can be damaged, which can lead to numbness, tingling, or muscle weakness in the affected area. In most cases, these nerve injuries are temporary and heal on their own over time. However, in rare cases, permanent nerve damage can occur, requiring further medical treatment.

Summary:

The risks and complications associated with hip replacement surgery are serious aspects that must be considered when deciding whether to undergo the procedure. Although most patients experience a successful and complication-free recovery, it is important to be aware of the potential risks and to work closely with the treating orthopedic surgeon to identify and treat any possible complications early on.

Alternatives to hip replacement

Although hip replacement is an effective treatment option for various hip joint problems, there are also alternative treatment methods that can be considered in certain cases. This chapter will discuss some of the most common alternatives to hip replacement in more detail:

Conservative treatment methods:

For patients with early stages of hip joint problems such as osteoarthritis, conservative treatment methods can be considered. These include physical therapy, pain medication, anti-inflammatory drugs, weight loss, and injections of corticosteroids or hyaluronic acid into the affected joint. These treatments can help relieve pain and improve hip joint function without the need for surgery.

Hip realignment surgery:

For patients with certain anatomical abnormalities or deformities of the hip joint, hip realignment surgery can be an alternative treatment option. This procedure alters the position of the femur within the hip joint to reduce stress on the joint and improve functionality. Hip realignment surgery is typically performed on younger patients with hip dysplasia or hip instability.

Resurfacing operations:

Resurfacing surgery, also known as surface replacement surgery, is an alternative form of hip replacement surgery in which the natural bone of the femoral head and acetabulum is preserved, and only the damaged joint surface is replaced. This surgical technique can be considered for younger and more active patients, as it offers greater range of motion and a lower likelihood of complications such as dislocations.

Partial dentures:

Partial hip replacements, also known as hip head replacements, are another alternative treatment option for patients with localized joint problems that do not affect the entire hip joint. In a partial hip replacement, only the damaged part of the hip joint is replaced, while the rest of the joint remains intact. This surgical technique can allow for a faster recovery and less stress on the surrounding tissue.

Summary:

There are various alternative treatment methods for hip joint problems, which can be considered depending on the individual needs and anatomical conditions of the patient. Before deciding on a treatment, it is important to consult thoroughly with an orthopedic surgeon and discuss all available options in order to determine the most suitable treatment for the individual patient.
