HIP

The design of  Surgival  Karey Primary Stems provides an ideal combination of resistance and fixation by minimising the geometry, offering a concept that is respectful of the patient’s anatomy.

Karey Revision Stems Surgival  specially designed for revision surgeries. The quadrangular section design and lengthening of the distal portion stays in line with the philosophy of the Karey Primary Stems.

The  Surgival  Self-locking Stem design is based on the original development made by Maurice E. Müller in 1976, with some of our own features that enhance its performance.

QUARTER® is a new and comprehensive anthropometric acetabular system compatible with total hip replacement and a wide range of circumduction.

Surgival Müller-style cups are based on the original design developed by Maurice Müller decades ago. Fully manufactured in ultra high molecular weight polyethylene (UHMWPE) and featuring a hemispheric design that enables maximum preservation of bone stock and guarantees uniform load distribution to the bone thanks to the close contact with the acetabular bone of less than 0.5 mm.

In 1940, Dr Austin Moore (1899–1963) performed the first metal hip replacement at Columbia Hospital in South Carolina. Moore designed a proximal femoral prosthesis with a large head and an approximate length of 30 cm that was attached with bolts to the end of the femoral shaft.

Since it was first used in 1954, the THOMPSON prosthesis has remained a popular implant for the treatment of hip fractures and its indications for use have changed very little since its advent It is primarily used in patients with intracapsular fracture.

Femoral heads Surgival are used for total and partial hip arthroplasties. Their function is to replace the anatomical joint element, providing the necessary mobility for proper functioning.

The biarticular head, also called a bipolar or bicentric head, was essentially designed  to reduce the friction that occurs, in the majority of cases and early on, in the acetabular cartilage upon direct contact with the metal head of an endoprosthesis in a classic hemiarthroplasty.

The endocephalic head  is indicated for hip hemiarthroplasties. Its design makes it possible to preserve the anatomical acetabulum and joint cartilage, regenerating  the degree of natural rotation that the joint originally had.
