Endoprosthesis of proximal epimethaphysis of femur bone

Valentin Dmitrievich Perepichka

Abstract

The invention relates to medical equipment, namely to traumatology, and can be used for hip joint replacement. The purpose of the invention is to prevent dislocation of the endoprosthesis from the acetabulum. The invention consists of a metal-polymer curved stem 2, placed in the medullary canal of the femur. Several holes are made on its surface in two mutually perpendicular planes, which are filled with plastic. A spherical head 3 is attached to the stem 2 using a thread, the position of which is fixed with additional screws. The head of the prosthesis contains a through channel 6, which then passes through the stem and ends on the femur. A continuous large-mesh lavsan tape 8 is passed through this channel, one end of which is fixed to the bottom of the acetabulum using a washer 10, and the other end, after exiting the channel, is disconnected and passed through additionally drilled holes in the prosthesis stem and bone and ends with wrapping the femur and tying it with a taut knot. The endoprosthesis allows for stable and constant fixation of the prosthesis stem in the medullary canal and prevents possible dislocations of the head from the acetabulum.

Description

The invention relates to medicine, more specifically to traumatology, and can be used for hip replacement in case of femur fractures or joint diseases.

The purpose of the invention is to prevent dislocation of the endoprosthesis from the acetabulum.

Fig. 1 shows the prosthesis after surgery, general view; Fig. 2 - metal-polymer stem and head, general view; 10 in Fig. 3 - acetabulum, front view; in Fig. 4 - section A - A in Fig. 3; in Fig. 5 - washer with holes for fixing lavsan tape in the acetabulum, front view; in Fig. 6 - washer with holes for fixing lavsan tape in the acetabulum, side view.

The endoprosthesis of the proximal epimetaphysis of the femur 1 (Fig. 1) contains a metal-polymer stem 2, to which a spherical head 3 is screwed (Figs. 1 20 and 2). On the surface of the stem 2 a row of holes 4 are made in two mutually perpendicular planes, filled with plastic. The head 3 is fixed in its final position with screws 5. A through channel 6 is made through the head 3, the threaded shank and the metal stem 2, and holes 7 are made in all the holes 4 (Figs. 1 and 2). A double large-mesh lavsan tape 8 with a width of 6 - 7 mm is pulled through the channel 6 and the holes 7, and the tape is tightly fixed on the surface of the acetabulum 9 with the help of a washer 10 (Figs. 5 and 6) with two holes for passing the lavsan tape 8 (Figs. 5 and 6). To do this, a hole 11 is made in the acetabulum 9, where the round ligament itself was located, and a gap 2 is cut (Figs. 3 and 4). The washer 10 is pushed through the hole 11, and the lavsan tape together with the washer O is advanced into the gap 12. Thus, the lavsan tape is tightly fixed in the acetabulum. The hole 11 is closed with a transplant. Through the opening of the channel 6, a through hole 13 is drilled through the bone 1, after which the lavsan tape, fixed on the bottom of the acetabulum, is passed through the channel 6 onto the surface of the bone 1, where it is fixed with a knot 14, through the bone 1 and the leg of the prosthesis in places where it is filled with polymer, holes 7 are drilled in two mutually perpendicular planes, the tape 8 is separated into two parts and passed through the holes 7. At the end, the bone is braided with the tape 8 (Fig. 1) and fixed with a weaver's knot 15 (Fig. 1). The section of the double tape 8 between the head 3 and the acetabulum 9 forms an artificial ligament 16 (Fig. 1). The bone is braided with maximum tension. After 12-14 days, the lavsan tape, as a foreign body of the body, begins to be covered with a connective tissue capsule, which increases the strength of fixation of the prosthesis leg.

The endoprosthesis creates a positive effect, consisting in stable fixation of the prosthesis leg in the medullary canal of the femur, and this is achieved for the first time by fixing it with the help of lavsan tape by tying. Fixation is carried out with a material soft compared to bone, which eliminates the effect of this material on the bone during the life of the patient and does not allow the prosthesis leg to loosen. An important feature of the semi-prosthesis is the creation of an artificial round ligament, which prevents the likelihood of dislocation of the prosthesis and relieves the patient from operations aimed at eliminating these dislocations.

Claims

An endoprosthesis for the proximal epimetaphysis of the femur, comprising a curved metal-polymer stem, on the surface of which, in two mutually perpendicular planes, openings are made, filled with plastic, a spherical head, connected to the stem by means of a thread, characterized in that, in order to prevent dislocation of the endoprosthesis from the acetabulum, a large-mesh tape with a washer is inserted into it for fastening to the bottom of the acetabulum, and a through channel is made in the spherical head for laying the large-mesh tape.

Vertebrates

VERTEBRATES According to the molecular clock, a specific method for dating phylogenetic events, vertebrates (Vertebrata) separated from arthropods (Arthropoda) 976±97 Ma (2004HedgesSB_ShoeJL). The latter began to dominate in species diversity with the Cambrian burst of radiation, which occurred 520 Ma (2010EdgecombeGD). This ratio in the fauna of the Earth is still preserved. Approximately 525 Ma, the phylum Chordates separated from the group of bilaterally symmetrical animals (1995ChenJY_ZhouGQ). In turn, the evolution of chordate organisms led to the formation of the first vertebrates at least 500 Ma, from which the jawed mouths 450-400 Ma descended, becoming the ancestors of the placoderms or "armored" fish (Placodermi) (1979 НаумовНП _ КарташевНН ).

Who, When, and Where Wrote the Book of Genesis?

Who, When, and Where Wrote the Book of Genesis? A Medical Hypothesis By Sergey V. Arkhipov, MD, PhD & Lyudmila N. Arkhipova, BSN CONTENT [i] Abstract [ii] Introduction [iii] Egyptian physician [iv] Asian diviner [v] Conclusion [vi] References [vii] Application [i] Abstract The Book of Genesis is an example of an ancient literary text that contains important medical insights. We propose that it was written in northern Egypt in the late 17th century BCE, approximately ten years after the Minoan eruption. The protograph likely emerged from the collaboration between an Asiatic seer, who rose to the rank of an Egyptian official, and an Egyptian physician-encyclopedist. By refining its dating and authorship, this hypothesis positions Genesis as a credible source of medical and historical data, thereby enhancing its value for interdisciplinary research.
