Definitions

  • the invention is about the femoral components developed for the surgical treatment of human hip fracture and coxofemoral diseases.
  • the invention is especially about the adjustable modular prostheses after the prosthesis' reduction to the acetabulum.
  • prostheses are the metallic formations that ensure the connection and function between the acetabulum in the pelvis and the main femur bone after the reduction of fractured or diseased bone in such cases as proximal femoral fracture and the surgical treatment of coxofemoral diseases.
  • the said prosthesis consists of three main parts. In the acetabulum, it has a spherical head that allows movement. The component which has the control of the head and ensures the movement transmission to the leg is the neck. On the other end of the neck - which is anatomically appropriate, thin-long, and curved at a certain angle - there is the stem fixing the prosthesis to femur. The stem is located in the medulla.
  • the stem In the modals with fixed neck-stem part, the stem is located lengthways in the medulla in femur. As the anteversion angle is set through winding according to the femur, fixing a mistake that might be made shall create a great problem. If there is a problem with the anteversion angle in a cemented prosthesis, you'll need to take the prosthesis out in order to reset the angle. Osteotomy needs to be applied to take out the prosthesis, which shall weaken the bone's strength and create post-treatment problems. It is easier to take out the prosthesis if a cementless stem has been used. However, as the medulla has loosened in that case, a stem of a bigger size needs to be located, and this shall cause the femur's loss of strength.
  • the stem is long especially in revision total hip prostheses -combined hip prostheses replacing the acetabulum and the femoral head- and in trochanteric partial prostheses -replacing the femoral head in the fractures in trochanteric area- (trochanter; the upper part of the femur). As a result of this length, there are many problems in calculating the anteversion angle.
  • Neck length and offset adjustment are performed in two different ways.
  • the neck is long or short according to the size of the stem.
  • the mobile neck part is mounted in the stem.
  • the other way of neck length and offset adjustment is performed at the head part.
  • the head is made for different lengths (small, medium, long, xl).
  • neck lengths of the femoral components that are still used are adjusted before reduction on the acetabulum, no matter what kind of femoral components exist. In that case, it is usually not possible to adjust the patient's anatomic neck length.
  • Reduction is performed hard if the neck length has been adjusted in accordance with the anatomic measures and femoral head cannot skip the edge of the acetabulum during reduction. In that case, if the reduction has been performed, though rarely, it shall cause the partial prosthesis' protrusion in the acetabulum and movement limitation in the hip. However, it depends on the bone structure, too.
  • angle adjustment is made possible through connecting the modular neck to the cylindrical stem.
  • These applications are the modular ones consisting of three parts (head, neck, stem) of different geometries and sizes; and ensuring the adjustability of these components according to each other. After fixing the prosthesis; a bolt, socketed system or a notch is used to connect the three components with their final forms and to prevent movement.
  • the modular orthopedic hip prosthesis consists of three main components -a stem, a proximal body and a neck-, and that these components are demountable and adjustable. It is also stated that the neck can be adjusted through rotating around the stem, the head part is rotatable and can be adjusted as an axis, and the prosthesis is the one with an inner component that ensures the locking of these movable elements with the help of a bolt.
  • an upper body has been improved in order to prevent the negative results of prosthesis.
  • the proximal body is in the form to be connected to and detached from the outer body with a conical socketed stem, a conical upper body narrowing downwards named conic end-piece which is sectionally elliptic has been realized.
  • the purpose of the invention is, with the help of totally new improvements, to eliminate the present disadvantages of femoral components developed for the surgical treatment of hip fractures and coxofemoral diseases.
  • Another purpose of the invention is to decrease the problems that appear during the operations and the postoperative complications related to the prostheses which are still being used.
  • At least one inner thread has been used.
  • This said inner thread makes the adjustment of the said head through rotating possible and is located in the inner hull of a cylindrical hole of which open side is through the inner head part in the form of a thread canal.
  • the neck length and off-set adjustment when the said head is rotated on the neck at least one neck part, the two ends of which have been connected to the head and the stem has been realized.
  • This said neck is in the form of a cylindrical bar with threads all over the surface.
  • At least one proximal part which has been formed on the neck side of the head has been realized.
  • This cylindrical part is in the form of creating degrees in the anatomic dimensions between the head and the neck, and it ensures leaning over the edge of acetabulum. In this way, the head shall not be dislocated from the edge of acetabulum and luxation shall not happen in case of the patient's overmovement. This way, overangled movement of the head (1) and the neck (2) has been limited.
  • the said fixing bolt cap is optionally without a head in the form to be embedded in the bolt hole.
  • At least one locknut which moves on the said neck and fixes the head on the neck has been formed.
  • At least one angled tip which is formed on the stem-side of the said neck, and which ensures movement within the limits of the anatomical angle has been used.
  • At least one neck fixing socket which is formed on the said stem on the neck side, which ensures movement within the limits of the anatomical angle and which ensures the standard head-neck-stem angle of 135° has been realized.
  • this femoral component is placed on the femur, it is easily located on its place (acetabulum) on the pelvis (reduction) and the anteversion angle of the patient can easily be adjusted according to his/her anatomical dimension.
  • the angle between the said neck and the angled tip is characterized with X.
  • the direction of the neck fixing socket is changed to the Q degrees which is the angle between the neck fixing socket and neck axis.
  • connection surface of the said angled tip in order to ensure the connection of the said angled tip and the neck fixing socket that are clamped together, has a longitudinal intricate notch form. In one of the preferred applications of the invention, in order to ensure the connection of the said angled tip and the neck fixing socket that are clamped together, the connection surface of the said neck fixing socket has an intricate notch form.
  • a thread has been opened and a double component prosthesis with a fixed neck-stem and a mobile head part has been formed.
  • the said thread has been opened, the neck (2) and stem (3) anteversion angle is fixed and these components are connected in a way that they can not open.
  • At least one round pinned stem which is connected to the femur, which has lengthwise chamfers to prevent rotation in the femoral medulla has been realized.
  • the neck can be adjusted and connected through rotating.
  • the anteversion angle of the head in order to ensure that the anteversion angle of the head can be adjusted after the said pinned stem has been placed in the medulla and in order to ensure its connection to the pinned stem, at least one rotatable upper body part which has been formed below the said neck, and which ensures connection to the said pinned stem through adjustment. So that this rotatabl ⁇ upper body said can accord with the defect in the femur; the neck is placed over the rotatable upper body.
  • the said prosthesis can become a revision total hip prosthesis or a partial prosthesis for trochanteric fractures when necessary. In this way, the anteversion angle of the head part can be adjusted after the said pinned stem has been placed in the medulla.
  • At least one rotatable lower body which is formed below the neck and which can be connected to the said pinned stem through adjustment has been realized. So that this rotatable lower body can accord with the defect in the femur, it has been placed below the rotatable lower body.
  • the said prosthesis can become a revision total hip prosthesis or a partial prosthesis for trochanteric fractures when necessary. In this way, the anteversion angle of the head part can be adjusted after the said pinned stem has been placed in the medulla.

  • At least one left bolt which is connected to the left bolt fixing socket and which prevents the bolt from loosening has been formed.
  • femur in case of a problem about the anteversion angle or the neck length after the placement of the prosthesis, femur shall not be operated on as the stem isn't taken out of the femur in order to be fixed. For this reason, the durability and the maintainability of the femur shall not deteriorate. Thence, the prosthesis shall create great advantages in preventing complications and shortening the duration of the operation.
