Method of endoprosthetics of proximal end of femur

Gennady Evtikhievich Dudko

Abstract

Изобретение относится к медицине, а именно к ортопедии и травматологии, и используется при эндопротезировании проксимального конца бедренной кости. С целью профилактики смещения головки протеза и обеспечения движения в раннем послеоперационном периоде производят резекцию измененной части бедренной кости, устанавливают полимер-титановый эндопротез, формируют каналы в области дна вертлужной впадины, в головке и шейке эндопротеза, в большом вертеле, проводят через них ленту и фиксируют ее концы.

Description

In the lateral position, the hip joint area is opened. The proximal end of the femur is exposed. The head of the femur with the remains of the neck is removed. A bed for the endoprosthesis is formed in the medullary cavity of the femur. Two holes are made with an awl in the subtrochanteric region of the femur for the artificial tape. The polymer-titanium prosthesis is installed by inserting the endoprosthesis stem into the medullary cavity of the femur until it stops in the intertrochanteric region. The remains of the round ligament are removed in the area of the bottom of the acetabulum. A channel with a diameter of 6-8 mm is formed at the place of its attachment with a drill, through which the end of the tape with a dumbbell-shaped stop is inserted into the pelvic cavity. The tape is pulled by the ends and it is made sure that the dumbbell-shaped stop rests against the bottom of the acetabulum. The free ends of the tape are passed through a pre-formed Y-shaped channel in the head and neck of the endoprosthesis and the corresponding holes in the greater trochanter using a wire loop. The head of the endoprosthesis is adjusted into the acetabulum, the hip is bent to an angle of 90° and moved outward as much as possible, the tape is pulled by the ends and tied or sutured in the subtrochanteric region. The damaged structures are sutured layer by layer: the joint capsule, muscles, fascia, subcutaneous tissue and skin. The limb is placed on an orthopedic pillow in a mid-physiological position. Movements in the joint are developed from the second day. After 5-7 days, patients learn to walk on crutches without support on the operated limb.

Example. Patient O., a pensioner, was hospitalized for a closed fracture of the right femoral neck. X-ray showed a subcapital fracture of the right femoral neck with displacement. He was treated with skeletal traction for 5 weeks. The treatment was ineffective. An endoprosthetic replacement surgery was performed using the traditional technique with a polymer-titanium endoprosthesis with the formation of a ligament between the head of the prosthesis and the bottom of the acetabulum using the described technique. The postoperative period was uneventful. Movements in the hip joint began on the second day, on the fifth day he was raised on crutches without support on the operated leg. The stitches were removed on the 12th day. He was examined two years later: he walks freely, over long distances without a cane. He fully cares for himself. There is no shortening of the limb. Range of motion in the operated joint: flexion 80°, extension 175°, abduction 35°, outward rotation 35°, inward rotation - 15°. Control radiographs of the right hip joint show no signs of arthrosis, the endoprosthesis stem is in the bone marrow cavity, oriented toward the center of the acetabulum. There are no signs of osteoporosis or subluxation. Five people were operated on using this technique with good results.

Thus, the proposed method prevents displacement of the endoprosthesis head during unipolar endoprosthetics and ensures patient activation in the early postoperative period.

Claims

A method for endoprosthetic replacement of the proximal end of the femur by resecting the altered portion of the femur with subsequent installation of an endoprosthesis, characterized in that, in order to prevent displacement of the head of the prosthesis and ensure movement in the early postoperative period, channels are formed in the area of the bottom of the acetabulum, in the head and neck of the endoprosthesis, a tape is passed through them and its ends are fixed.

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 ).

Fragments of t he book Pollux J. Onomasticum (166-76) edited by E. Bethe (1900). In Greek the author calls ligamentum capitis femoris (LCF) «ἰσχίον», and the concept of «ligament» is designated by the term «νεῦρον / ν εῦρα ». The term «ἰσχίον» was used by Rufus of Ephesus ( 2020ArkhipovSV_ProlyginaIV ). The fragment of the Onomasticum dealing with the LCF was quoted by Giovanni Filippo Ingrassia ( 1603IngrassiaeIP ) .
