3d printed hip replacement
A revolutionary 3D printed hip replacement device, composed of a femoral stem, femoral head, and acetabular cup, is transforming patient care by restoring mobility and alleviating hip joint pain effectively.
3D printed hip replacement
3D printed hip arthroplasty is an implantable medical device consisting of three parts: the femoral stem, the femoral head, and the acetabular cup, which can replace the damaged hip joint, restore the patient's mobility and relieve the patient's pain.
What are the components of a hip replacement?
Femoral stem: The femoral stem is an important component of a 3D printed hip replacement device designed to mimic the natural shape and function of the femur to provide enhanced stability and support for the artificial hip joint. Made from high-quality biocompatible materials, the femoral stem is custom designed to fit each patient's unique anatomy, ensuring a precise and safe fit that promotes healing. After the patient's femoral head is removed, the patient's femoral canal is reamed and the femoral stem is inserted, which can be cemented or not, depending on the patient's age, morphology, bone specificity and physician habits.
Femoral head: A spherical head made of metal materials cobalt-chrome alloy and titanium alloy, polymer material or ceramic is applied to the upper end of the femoral stem, replacing the old damaged femoral head that has been removed, the femoral head is a supplement to the femoral stem, which acts as a "ball" of the hip joint, allowing the artificial joint to move smoothly and without restrictions. Manufactured using advanced 3D printing technology, the femoral head withstands the rigors of daily activities and provides long-lasting durability for patients seeking to regain their quality of life.
Acetabular Cup: The damaged cartilage at the top of the acetabulum, where the old bone is located, is removed and an acetabular implant is used, which can be fixed with screws or bone cement, inside this cup is a plastic, ceramic or metal inlay, the acetabular cup is another component of the 3D printed hip replacement device, which plays a key role in stabilizing the hip joint and promoting weight-bearing activities. Customized to each patient's unique hip anatomy, acetabular cups are designed to promote proper alignment and reduce the risk of dislocation, allowing patients to perform a variety of physical activities with confidence and comfort.
How long does a hip replacement last?
The longevity of a hip prosthesis depends mainly on the following factors:
The patient's age, body mass index and degree of activity, diameter of the prosthetic head, type of frictional moment.
The longevity of the implant is largely dependent on the composition of the implant, when the femoral head and the implant cup are made of metal or ceramic, the wear rate will be very low, and a wider femoral head can be used, limiting the risk of dislocation, it is important to note that when metal and metal, ceramic and ceramic implants are paired, there is a risk of dispersion of debris in the tissues around the implant, and ceramic implants are less damaged than metal implants.
Risks of hip prosthesis:
Risk of dislocation: is a major complication for patients, and the risk varies over time and may be related to the patient, surgery and implants, or postoperative follow-up.
Risk of infection: There is a risk of infection in any surgical procedure, when the implant is implanted, due to the entry of foreign bodies into the body, this risk increases, the immune system is transferred, forming a local immunodeficiency area, and bacteria that cannot survive will grow on the foreign body, which is usually more likely to occur in the elderly because they have lower immunity, and other factors such as diabetes, obesity, smoking, and reduced immunity will increase the risk of infection.
Allergic reactions: Certain prosthetic materials may cause allergic reactions,
Risk of revision surgery: Failure of the prosthesis, wear or tear may require revision surgery.
Patients undergoing hip replacement surgery can expect significant improvements in mobility, pain relief, and overall quality of life. By harnessing the power of advanced technology and personalized medicine, orthopedic surgeons are able to provide patients with a truly transformative approach to hip replacement, tailored to their individual needs and preferences.
In addition to the clinical benefits, 3D printed hip replacement devices have contributed to the development of healthcare services by providing a more cost-effective and efficient solution for patients with hip problems. By streamlining the design and manufacturing process, orthopedic surgeons can now provide patients with a customized hip replacement device that is not only efficient, but also accessible to more people in need.
As the field of orthopedic surgery continues to advance, the use of 3D printed hip replacement devices is expected to revolutionize patient care and redefine the standard of care for patients with hip pain. By employing this innovative method of joint replacement, patients can look forward to a future in which mobility is restored, pain is reduced, and quality of life is significantly improved.
