METHOD OF MANUFACTURING A HIP JOINT SPACER IN AN UNSUPPORTABLE ACETABULUM Russian patent published in 2018 - IPC A61B17/00 A61F2/32 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, particularly to traumatology and orthopedics. Access is made to the hip joint with excision of nonviable tissues and fistulas. Remove all components of the endoprosthesis, followed by a thorough sanitation of its bed. Proximal part of sterilized femoral component of the head endoprosthesis is treated with bone cement with an antibiotic for 2–3 cm, set in the femur canal with an anteversion angle of 10–15° and the distance from the center of the head to a small trochanter equal to that on the opposite side. In zone of defect of the iliac body, using a drill with a diameter of 3–3.5 mm, two holes are formed with the passage of the second cortical layer of the ilium and determine their depth. Further spongy screws with a thread diameter of 6–6.5 mm are introduced, so that they protrude above the bone surface by 20–25 mm. In acetabulum a viscous mass of bone cement is laid so that it completely fills the acetabulum with all defects and the protruding parts of the screws. In cement mass femoral part of the spacer is inserted no more than the depth of the head. After polymerization of cement, drainage and suturing of the wound are performed.

EFFECT: method ensures stable fixation of the spacer in the unsupportable acetabulum.
