Hip

A short guide to your upcoming hip arthroplasty.

If your hips hurt, you may be considering undergoing hip replacement surgery.
We'll explain how your hips work and why the joint may wear out over time. Of course, we’ll also explain how hip prosthetic implants are made and what happens during hip arthroplasty.

Hip Anatomy The hip is a ball-and-socket joint made up of two main bones: the femur and the pelvis. The hip’s purpose is to guarantee stability, support, flexibility, and strength.

The femur's upper end, or femoral head, is sphere-shaped. It fits into a cavity, called the acetabulum, in the pelvis. A hip's ligaments limit movement, and the muscles, which insert in the small and large trochanter, join the bones together. A snug capsule surrounds the entire hip joint providing additional strength.

The hip joint is a mix of strength and flexibility. Its job is to give stability to the body and support any load during all activities involving the legs.

Hip Joint-specific
Diseases

Avascular necrosis

Avascular Necrosis occurs after severe trauma to the femoral head. Dislocation, fractures, or infractions can limit blood supply to bones, causing the femoral head to collapse.

Childhood Hip Diseases

Childhood-specific hip diseases, such as dysplastic hip syndrome, can be successfully treated at an early age. However, these diseases increase the risk of osteoarthritis in adulthood.

Hip Prosthetic implants Hip replacements occur because the cartilage in the hip wears away. During hip arthroplasty, the surgeon removes the damaged parts of the joint and replaces them with a prosthesis.

The femoral head implant consists of a metal or ceramic ball attached to a metal stem that fits into the femur. The fitting can be secured by using special cement. A plastic or ceramic liner, fitted into a metal socket, replaces the damaged acetabulum. This implant combination creates a new joint, designed to glide smoothly and painlessly.

Hip Implants can have different designs. Some implants feature special metal alloys, like our TT technology, to aid fixation. On the femoral side, the surgeon chooses the right type and size of the prosthetic stem. Important considerations include a patient’s wishes, their bone quality, and their age.
Hip Arthroplasty
  • The surgeon begins the hip replacement surgery by accessing the joint. The orthopedic approach, whether anterior, lateral, or posterolateral, will depend on the surgeon's preference and experience.
  • The surgeon then dislocates and removes the femoral head from the acetabulum. They will also rework the socket to allow the metal cup to fit perfectly. Finally, dedicated instruments are used to hollow the inside of the femur to insert the metal stem.
  • All components can be cemented or uncemented. The former relies on a special bone cement to anchor the implant to the bone. The latter is ensured by the tightness of the fit and dedicated materials that allow the bone to grow into the implant.
  • Once everything fits in place, the orthopedic surgeon closes the incision with serval layers of stitches or metal staples. A bandage is applied, and the patient is returned to the recovery room.
